PURPOSE OF REVIEW: Borderline intellectual functioning (BIF) is a descriptive v-code that is often used, especially in forensic settings, as if it were a full-fledged disorder. Various historical and other aspects of this classification are reviewed, and commentary is made on the question of whether to upgrade BIF to a regular psychiatric category, or to eliminate it by folding it into an already recently expanded category of intellectual developmental disorder (IDD). RECENT FINDINGS: Full-scale intelligence quotient (IQ) is an outmoded concept that is decreasingly being used...

Wildlife conservation and management on military lands must be accomplished in the context of military readiness, which often includes ground-based training that is perceived to conflict with wildlife needs and environmental regulations. From 2008‒2012, we examined territory density, pairing success, and fledging success of the federally endangered golden-cheeked warbler (Setophaga chrysoparia; hereafter warbler) in relation to removal of small-diameter trees from the understory of mature oak-juniper (Quercus-Juniperus) woodland at the 87,890 ha Fort Hood Military Reservation in central Texas...

Interventional radiology (IR) has evolved into a full-fledged clinical specialty with attendant patient care responsibilities. Success in IR now requires development of a full clinical practice, including consultations, inpatient admitting privileges, and an outpatient clinic. In addition to technical excellence and innovation, maintaining a comprehensive practice is imperative for interventional radiologists to compete successfully for patients and referral bases. A structured approach to periprocedural care, including routine follow-up and early identification and management of complications, facilitates efficient and thorough management with an emphasis on quality and patient safety...

How populations and communities reassemble following disturbances are affected by a number of factors, with the arrival order of founding populations often having a profound influence on later populations and community structure. Kasatochi Island is a small volcano located in the central Aleutian archipelago that erupted violently August 8, 2008, sterilizing the island of avian biodiversity. Prior to the eruption, Kasatochi was the center of abundance for breeding seabirds in the central Aleutian Islands and supported several breeding pairs of peregrine falcons (Falco peregrinus)...

BACKGROUND: Mental, neurological and substance use disorders contribute to a significant proportion of the world's disease burden, including in low and middle income countries (LMICs). In this study, we focused on the health systems required to support integration of mental health into primary health care (PHC) in Ethiopia, India, Nepal, Nigeria, South Africa and Uganda. METHODS: A checklist guided by the World Health Organization Assessment Instrument for Mental Health Systems (WHO-AIMS) was developed and was used for data collection in each of the six countries participating in the Emerging mental health systems in low and middle-income countries (Emerald) research consortium...

Bacteria have had a fundamental impact on vertebrate evolution not only by affecting the evolution of the immune system, but also generating complex interactions with behavior and physiology. Advances in molecular techniques have started to reveal the intricate ways in which bacteria and vertebrates have coevolved. Here, we focus on birds as an example system for understanding the fundamental impact bacteria have had on the evolution of avian immune defenses, behavior, physiology, reproduction and life histories...

Thyroid hormones are closely linked to the hatching process in precocial birds. Previously, we showed that thyroid hormones in brain had a strong impact on filial imprinting, an early learning behavior in newly hatched chicks; brain 3,5,3'-triiodothyronine (T3) peaks around hatching and imprinting training induces additional T3 release, thus, extending the sensitive period for imprinting and enabling subsequent other learning. On the other hand, blood thyroid hormone levels have been reported to increase gradually after hatching in altricial species, but it remains unknown how the brain thyroid hormone levels change during post-hatching development of altricial birds...

In vertebrates, exposure to stressful stimuli early in development may alter the activity of the hypothalamo-pituitary-adrenal (HPA) axis, with the potential for fitness consequences later in life. For altricial species, whose young rely on their parents for food, warmth, and protection from predators, adult behavior can modify the impact of some stressors on their offspring after birth or hatching. We have shown that single bouts of cooling that normally occur when brooding females leave the nest elevate corticosterone secretion in very young free-living eastern bluebird (Sialia sialis) chicks...

Conspecific individuals inhabiting nearby breeding colonies are expected to compete strongly for food resources owing to the constraints imposed by shared morphology, physiology, and behavior on foraging strategy. Consequently, colony-specific foraging patterns that effectively partition the available resources may be displayed. This study aimed to determine whether intraspecific resource partitioning occurs in two nearby colonies of Lesser Frigatebirds (Fregata ariel). A combination of stable isotope analysis and GPS tracking was used to assess dietary and spatial partitioning of foraging resources during the 2013 and 2014 breeding seasons...

Patients with cancer who live at home often require help with activities of daily living, basic medical care (eg, injections), social needs, and patient advocacy. Most of that support comes from intimate caregivers, typically members of the patient's family. These family caregivers themselves require support so that they can be effective and maintain their own well-being while caring for the patient with cancer. Research shows that support for caregivers contributes to achieving these goals. We propose a four-part framework for supporting family caregivers: (1) assess caregivers' needs using formal measures, just as the cancer patient's own needs are assessed, (2) educate caregivers for their caregiving roles, most notably, with training in the low-level medical support that cancer patients require at home, (3) empower caregivers to become full-fledged members of the patient's cancer team, all working toward common goals, and (4) assist caregivers proactively in their duties, so that they retain a sense of control and self-efficacy rather than having to react to imminent medical crises without sufficient resources at their disposal...

The effects of acute environmental stressors on reproduction in wildlife are often difficult to measure because of the labour and disturbance involved in collecting accurate reproductive data. Stress hormones represent a promising option for assessing the effects of environmental perturbations on altricial young; however, it is necessary first to establish how stress levels are affected by environmental conditions during development and whether elevated stress results in reduced survival and recruitment rates...

Studies of blood parasite infection in nestling birds rarely find a high prevalence of infection. This is likely due to a combination of short nestling periods (limiting the age at which nestlings can be sampled) and long parasite prepatent periods before gametocytes can be detected in peripheral blood. Here we examine rates of blood parasite infection in nestlings from three Columbid species in the UK. We use this system to address two key hypotheses in the epidemiology of avian haemoparasites: first, that nestlings in open nests have a higher prevalence of infection; and second, that nestlings sampled at 14 days old have a higher apparent infection rate than those sampled at 7 days old...

Poor environmental conditions experienced during early development can have negative long-term consequences on fitness. Animals can compensate negative developmental effects through phenotypic plasticity by diverting resources from non-vital to vital traits such as spatial memory to enhance foraging efficiency. We tested in young feral pigeons (Columba livia) how diets of different nutritional value during development affect the capacity to retrieve food hidden in a spatially complex environment, a process we refer to as "spatial memory"...

This article raises the question of whether in both the United States and in France, an individual's autonomy and private decision-making right(s) in matters of health care and access to reproductive technologies can be conciliated with the general interest, and more specifically, the role of the State. Can a full-fledged right to privacy, the ability to exercise one's autonomy, exist alongside the general interest, and depend neither on financial resources like in the United States nor on centralised government decisions or the medical hierarchy like in France? The contrast between these two modern democracies justify the importance of comparing them...

Telomeres are nucleotide sequences located at the ends of chromosomes that promote genome stability. Changes in telomere length (dynamics) are related to fitness or life expectancy, and telomere dynamics during the development phase are likely to be affected by growth and stress factors. Here, we examined telomere dynamics of black-tailed gull chicks (Larus crassirostris) in nests with and without siblings. We found that the initial telomere lengths of singletons at hatching were longer than those of siblings, indicating that singletons are higher-quality chicks than siblings in terms of telomere length...

Lack 18:125-128 (1967) proposed that clutch size in precocial species was regulated by nutrients available to females during breeding. Drent and Daan 68:225-252 (1980) proposed the individual optimization hypothesis, whereby individual state determines the optimal combination of breeding date and clutch size. Neither hypothesis accounts for variation in nutrients among females at the end of egg laying, strong right truncations in clutch size distributions, or the fact that many species with precocial young are determinate layers...

Breeding mistiming is increasingly frequent in several ecosystems in the face of current climate change. Species belonging to higher trophic levels must employ mechanisms to reduce it. One of these mechanisms is hatching asynchrony, with the eggs in a clutch hatching over a period of several days. Some authors have suggested it to be adaptive when food is unpredictable. However, these birds can also suffer associated costs. We tested whether a species with higher foraging efficiency avoid hatching asynchrony compared to its sister species...

BACKGROUND: Co-evolutionary arms-races result in spatio-temporally dynamic relationships between interacting species, e.g., brood parasites and their avian hosts. However, majority of avian co-evolutionary studies are limited to "snap-shots" of a single breeding season in an open-nesting host. In a long-term study (11 breeding seasons), we explored a unique system between the brood parasitic common cuckoo (Cuculus canorus) and its host, the common redstart (Phoenicurus phoenicurus) which is exceptional among all cuckoo hosts due to being a cavity nester...

We determined mercury (Hg) concentrations in feathers of osprey (Pandion haliaetus), both nestlings (n = 95) and adults (n = 110), across peninsular Florida and the Florida Keys during February-August 2014. Feathers plucked from nestlings, aged 3-7 weeks, contained Hg concentrations that ranged from 0.338 to 45.79 mg/kg and averaged 6.92 ± 7.58 mg/kg (mean ± 1SD). Feathers shed from adults contained significantly higher concentrations ranging from 0.375 to 93.65 mg/kg, with an average of 17.8 ± 16...
