Representations of Mental Health in Young Adult Literature: A Cultural Analysis of the Three Ps of Patient, Practitioner and Population

This thesis examines the representations of mental health in young adult literature by categorizing texts into a new framework established by this thesis as the Three Ps of patient, practitioner and population. Looking at the Three Ps from an interdisciplinary, cross-cultural view recognizes ways in which literature with themes of mental health is progressively changing with the times. In analyzing John Neufeld’s Lisa, Bright and Dark (1969), Emily Danforth’s The Miseducation of Cameron Post (2012), and Ned Vizzini’s It’s Kind of a Funny Story (2006), this thesis identifies the changes in mental health visibility and awareness, Sexual Orientation Change Efforts’ false belief in homosexuality as mental illness, and advances in promoting mental illness destigmatization. Employing mental health-based young adult literature in secondary and post-secondary settings, along with mental health education, can increase empathy and mental health awareness

Using the Five Ps: Conceptualizing COVID-19-Related Mental Health Concerns

The COVID-19 pandemic has resulted in rising mental health concerns. As individuals experience loneliness, anxiety, and depression related to the pandemic, counselors-in-training navigate their treatment of clients while also living through the pandemic and its polarization. The authors present the Five Ps, a case conceptualization model that supervisors can use to help beginning counselors consider the history and context of the presenting concerns of clients, in addition to utilizing clients’ strengths in treatment. The authors provide a case illustration using the Five Ps in a supervision setting and discuss implications for supervision and future research

Recombinant tissue plasminogen activator in the treatment of suprachoroidal hemorrhage

Nancy Kunjukunju1, Christine R Gonzales2, William S Rodden21Ochsner Medical Center, New Orleans, Louisiana; 2Retina and Vitreous Center of Southern Oregon, Ashland, Oregon, USABackground: Suprachoroidal hemorrhages are a vision-threatening complication, and poor visual outcome is correlated with increasing hemorrhage complexity. The recommended time of surgical drainage is 10–14 days after the hemorrhage begins to liquefy. We describe a case in which recombinant tissue plasminogen activator (r-tPA), alteplase, is injected within the suprachoroidal space before surgery to assist in the drainage of an organized clot prior to liquefaction. This is a report of a technique in which r-tPA is used in the intrachoroidal space to target the organized clot of suprachoroidal hemorrhage prior to drainage.Case report: A 62-year-old male presented 12 days after retinal detachment repair with sudden ocular pain and vision loss after a Valsalva maneuver. Vision was light perception only, and intraocular pressure was 43 mmHg. Diagnosed with hyphema and suprachoroidal hemorrhage, the patient underwent surgery the following day. An injection of r-tPA 100 µg was given intracamerally, and an additional dose of r-tPA 100 µg was injected into the suprachoroidal space prior to surgery. Liquified by r-tPA, the clot was expressed through the sclerotomies. Best corrected vision in the eye eight months after the drainage procedure was 20/40.Conclusion: To the author’s knowledge, this is the first reported case in which r-tPA was successfully injected in the suprachoroidal space to liquefy and drain a suprachoroidal hemorrhage prior to natural dissolution.Keywords: tPA, suprachoroidal hemorrhage, vision los

Decision-support model to explore the feasibility of using translocation to restore a woodland caribou population in Pukaskwa National Park, Canada

The distribution and abundance of woodland caribou (Rangifer tarandus caribou) have declined dramatically in the past century. Without intervention the most southern population of caribou in eastern North America is expected to disappear within 20 years. Although translocations have reintroduced and reinforced some populations, approximately half of caribou translocation efforts fail. Translocations are resource intensive and risky, and multiple interrelated factors must be considered to assess their potential for success. Structured decision-making tools, such as Bayesian belief networks, provide objective methods to assess different wildlife management scenarios by identifying the key components and relationships in an ecosystem. They can also catalyze dialogue with stakeholders and provide a record of the complex thought processes used in reaching a decision. We developed a Bayesian belief network for a proposed translocation of woodland caribou into a national park on the northeastern coast of Lake Superior, Ontario, Canada. We tested scenarios with favourable (e.g., good physical condition of adult caribou) and unfavourable (e.g., high predator densities) conditions with low, medium, and high numbers of translocated caribou. Under the current conditions at Pukaskwa National Park, augmenting the caribou population is unlikely to recover the species unless wolf densities remain low (<5.5/1000 km2) or if more than 300 animals could be translocated

Alcohol-preferring P rats emit spontaneous 22-28 kHz ultrasonic vocalizations that are altered by acute and chronic alcohol experience

BACKGROUND: Emotional states are often thought to drive excessive alcohol intake and influence the development of alcohol use disorders. To gain insight into affective properties associated with excessive alcohol intake, we utilized ultrasonic vocalization (USV) detection and analyses to characterize the emotional phenotype of selectively bred alcohol-preferring (P) rats; an established animal model of excessive alcohol intake. USVs emitted by rodents have been convincingly associated with positive (50-55 kHz frequency-modulated [FM]) and negative (22-28 kHz) affective states. Therefore, we hypothesized that 50-55 and 22-28 kHz USV emission patterns in P rats would reveal a unique emotional phenotype sensitive to alcohol experience. METHODS: 50-55 kHz FM and 22-28 kHz USVs elicited from male P rats were assessed during access to water, 15 and 30% EtOH (v/v). Ethanol (EtOH; n = 12) or water only (Control; n = 4) across 8 weeks of daily drinking-in-the-dark (DID) sessions. RESULTS: Spontaneous 22-28 kHz USVs are emitted by alcohol-naïve P rats and are enhanced by alcohol experience. During DID sessions when alcohol was not available (e.g., "EtOH OFF" intervals), significantly more 22-28 kHz than 50-55 kHz USVs were elicited, while significantly more 50-55 kHz FM than 22-28 kHz USVs were emitted when alcohol was available (e.g., "EtOH ON" intervals). In addition, USV acoustic property analyses revealed chronic effects of alcohol experience on 22-28 kHz USV mean frequency, indicative of lasting alcohol-mediated alterations to neural substrates underlying emotional response. CONCLUSIONS: Our findings demonstrate that acute and chronic effects of alcohol exposure are reflected in changes in 22-28 and 50-55 kHz FM USV counts and acoustic patterns. These data support the notion that initiation and maintenance of alcohol intake in P rats may be due to a unique, alcohol-responsive emotional phenotype and further suggest that spontaneous 22-28 kHz USVs serve as behavioral markers for excessive drinking vulnerability

Alcohol enhances unprovoked 22-28 kHz USVs and suppresses USV mean frequency in High Alcohol Drinking (HAD-1) male rats

Heightened emotional states increase impulsive behaviors such as excessive ethanol consumption in humans. Though positive and negative affective states in rodents can be monitored in real-time through ultrasonic vocalization (USV) emissions, few animal studies have focused on the role of emotional status as a stimulus for initial ethanol drinking. Our laboratory has recently developed reliable, high-speed analysis techniques to compile USV data during multiple-hour drinking sessions. Since High Alcohol Drinking (HAD-1) rats are selectively bred to voluntarily consume intoxicating levels of alcohol, we hypothesized that USVs emitted by HAD-1 rats would reveal unique emotional phenotypes predictive of alcohol intake and sensitive to alcohol experience. In this study, male HAD-1 rats had access to water, 15% and 30% EtOH or water only (i.e., Controls) during 8 weeks of daily 7-h drinking-in-the-dark (DID) sessions. USVs, associated with both positive (i.e., 50-55 kHz frequency-modulated or FM) and negative (i.e., 22-28 kHz) emotional states, emitted during these daily DID sessions were examined. Findings showed basal 22-28 kHz USVs were emitted by both EtOH-Naïve (Control) and EtOH-experienced rats, alcohol experience enhanced 22-28 kHz USV emissions, and USV acoustic parameters (i.e., mean frequency in kHz) of both positive and negative USVs were significantly suppressed by chronic alcohol experience. These data suggest that negative affective status initiates and maintains excessive alcohol intake in selectively bred HAD-1 rats and support the notion that unprovoked emissions of negative affect-associated USVs (i.e., 22-28 kHz) predict vulnerability to excessive alcohol intake in distinct rodent models

Praying Sitting Position for Pineal Region Surgery : An Efficient Variant of a Classic Position in Neurosurgery

BACKGROUND: The sitting position has lost favor among neurosurgeons partly owing to assumptions of increased complications, such as venous air embolisms and hemodynamic disturbances. Moreover, the surgeon must assume a tiring posture. We describe our protocol for the "praying position" for pineal region surgery; this variant may reduce some of the risks of the sitting position, while providing a more ergonomic surgical position. METHODS: A retrospective review of 56 pineal lesions operated on using the praying position between January 2008 and October 2015 was performed. The praying position is a steeper sitting position with the upper torso and the head bent forward and downward. The patient's head is tilted about 30 degrees making the tentorium almost horizontal, thus providing a good viewing angle. G-suit trousers or elastic bandages around the lower extremities are always used. RESULTS: Complete lesion removal was achieved in 52 cases; subtotal removal was achieved in 4. Venous air embolism associated with persistent hemodynamic changes was nonexistent in this series. When venous air embolism was suspected, an immediate reaction based on good teamwork was imperative. No cervical spine cord injury or peripheral nerve damage was reported. The microsurgical time was CONCLUSIONS: A protocolized praying position that includes proper teamwork management may provide a simple, fast, and safe approach for proper placement of the patient for pineal region surgery.Peer reviewe

Effect of Maternal Exercise on Adverse Cardio-Pulmonary Responses in Offspring Exposed to Post-Natal Chronic Hypoxia

Emerging evidence shows exercise by women throughout pregnancy (i.e., maternal exercise) endows the offspring with positive health benefits and resistance to many diseases later in life. PURPOSE: To determine if maternal exercise reduces unfavorable cardiopulmonary development and improves exercise capacity in offspring after chronic hypoxic exposure throughout early life. METHODS: Female adult C57BL/6J mice were randomly assigned to one of the following groups: high altitude, sedentary (HS), high altitude, active (HE), or the respective, low-altitude conditions (LS or LE). Pregnant females in the exercise groups performed voluntary wheel running during mating and the perinatal period (about 4 weeks). Three days after birth, the pups in the high-altitude groups were exposed to chronic hypobaric hypoxia (450mmHg). When pups were eight weeks old, body size (weight and tail length) was measured and exercise capacity was assessed via a Rotarod test. Terminal procedures were performed to measure right ventricular systolic pressure (RVSP), hematocrit, and heart remodeling (Fulton’s Index: right ventricular weight ratio to bodyweight (RV/BW) and to the left ventricle plus septum (RV/LV+S)). RESULTS: All variables measured had a main effect for altitude (pCONCLUSION: Chronic hypoxia decreases exercise capacity and attenuates growth. This stress also induces potentially harmful cardiovascular changes, such as high blood viscosity, RVSP, and right ventricular hypertrophy. Our results indicate that maternal exercise may attenuate some of the negative effects of chronic hypoxia in the offspring, but does not prevent significant development impairments

Comparative Antimicrobial Activity of Granulysin against Bacterial Biothreat Agents

Granulysin is a cationic protein produced by human T cells and natural killer cells that can kill bacterial pathogens through disruption of microbial membrane integrity. Herein we demonstrate antimicrobial activity of the granulysin peptide derived from the active site against Bacillus anthracis, Yersinia pestis, Francisella tularensis, and Burkholderia mallei, and show pathogen-specific differences in granulysin peptide effects. The susceptibility of Y. pestis to granulysin is temperature dependent, being less susceptible when grown at the flea arthropod vector temperature (26°C) than when grown at human body temperature. These studies suggest that augmentation of granulysin expression by cytotoxic lymphocytes, or therapeutic application of granulysin peptides, could constitute important strategies for protection against select agent bacterial pathogens. Investigations of the microbial surface molecules that determine susceptibility to granulysin may identify important mechanisms that contribute to pathogenesis
