Youths' mental health is at a crisis level, with mental health problems doubling in the US since the pandemic began. To compound the mental health crisis, there is a global loneliness epidemic, with emerging adults worldwide experiencing some of the highest rates. One study with two phases examined the influence of social support and loneliness on mental health in US emerging adults during the pandemic, including changes in these relationships over one year. Emerging adults ( N = 449) completed online questionnaires via Prolific in May 2020 (Phase 1) and again from January to May 2021 ( N = 253; Phase 2). More perceived support was related to reduced loneliness, with family support having the most significant influence. Loneliness mediated the link between perceived support and adverse health outcomes. Higher loneliness predicted more perceived stress and sleep difficulties concurrently and over time. There was a bidirectional relationship between loneliness and depression, such that higher levels of either variable at Time 1 predicted increases in the other over time. Results highlight the detrimental impact of loneliness on emerging adults' mental health.

Evaluation of the implementation process of family nursing in oncology Abstract., Background: The confrontation with a life-threatening cancer disease and the resulting consequences are a great burden for patients as well as for their family members. Family nursing based on the Calgary Model was implemented on a German oncological inpatient unit in order to strengthen the family's ability to self-help., Aim: The objectives were a) to systematically record, evaluate and if necessary to modify the implementation process, b) to highlight promoting and inhibiting factors and c) to derive recommendations for transferability to other oncological units., Methods: The implementation process was examined by means of two group interviews with nurses, five interviews with other members of the treatment team, and observations of, in each case four, family assessments, family interviews and family-related team meetings., Results: Family nursing could be implemented in a modified form. Genograms and ecomaps have become part of the admission interview. In family interviews, needs of the entire family were determined with the help of circular communication. Family-related team meetings were carried out according to an adapted method of the reflecting team. The complete implementation of family nursing was impeded by the lack of professional consulting competences of the nursing staff, the system of nursing care delivery and lack of time., Conclusion: An implementation of family nursing in other oncological units is recommended under modified preconditions.

Objective: Dysphagia and associated aspiration pneumonia are commonly reported sequelae of Parkinson's disease (PD). Previous studies of swallowing in patients with PD have described prolonged pharyngeal transit time, delayed onset of pharyngeal transit, cricopharyngeal (CP) achalasia, reduced pharyngeal constriction, and slowed hyolaryngeal elevation. These studies were completed using inconsistent evaluation methodology, reliance on qualitative analysis, and a lack of a large control group, resulting in concerns regarding diagnostic precision. The purpose of this study was to investigate swallowing function in patients with PD using a norm-referenced, quantitative approach., Methods: This retrospective study includes 34 patients with a diagnosis of PD referred to a multidisciplinary voice and swallowing clinic. Modified barium swallow studies were performed using quantitative measures of pharyngeal transit time, hyoid displacement, CP sphincter opening, area of the pharynx at maximal constriction, and timing of laryngeal vestibule closure relative to bolus arrival at the CP sphincter., Results: Reduced pharyngeal constriction was found in 30.4%, and a delay in airway closure relative to arrival of the bolus at the CP sphincter was the most common abnormality, present in 62% of patients. Previously reported findings of prolonged pharyngeal transit, poor hyoid elevation, and CP achalasia were not identified as prominent features., (© The Author(s) 2015.)

The human amygdala is critical for social cognition from faces, as borne out by impairments in recognizing facial emotion following amygdala lesions [1] and differential activation of the amygdala by faces [2-5]. Single-unit recordings in the primate amygdala have documented responses selective for faces, their identity, or emotional expression [6, 7], yet how the amygdala represents face information remains unknown. Does it encode specific features of faces that are particularly critical for recognizing emotions (such as the eyes), or does it encode the whole face, a level of representation that might be the proximal substrate for subsequent social cognition? We investigated this question by recording from over 200 single neurons in the amygdalae of seven neurosurgical patients with implanted depth electrodes [8]. We found that approximately half of all neurons responded to faces or parts of faces. Approximately 20% of all neurons responded selectively only to the whole face. Although responding most to whole faces, these neurons paradoxically responded more when only a small part of the face was shown compared to when almost the entire face was shown. We suggest that the human amygdala plays a predominant role in representing global information about faces, possibly achieved through inhibition between individual facial features., (Copyright © 2011 Elsevier Ltd.

Background: Surgery is the most effective means of eliminating or reducing seizures in cases of medically refractory epilepsy. As elective surgery, however, there is little tolerance for complications. We have reviewed the early operative experience of a single epilepsy surgeon to identify the presence or absence of a surgical learning curve., Methods: All phase II (diagnostic) and phase III (therapeutic) procedures for epilepsy surgery during the surgeon's first 8 years of practice were retrospectively reviewed. Complications were analyzed and subdivided into major or minor. Trends in complication rates were evaluated., Results: During the first 8 years, there were 96 phase II and 94 phase III cases. Complications occurred in 26 (14%) of 190 cases, including 16 major (8%) and 10 minor (5%) complications. There was a decline in both the number and severity of complications associated with temporal lobectomy over time. Complications involving subdural grids shifted, over time, from those attributed to surgical technique or experience to those felt to be unavoidable risks of the procedure itself. Over time there was a decline in the proportion of major vs minor complications, but the overall complication rate remained stable., Conclusions: There appears to be a surgical learning curve for epilepsy surgery involving complications associated with removal of medial temporal lobe structures, which lessen as the surgeon's experience increases.

The prevalence and economic burden of neuropsychiatric disease are enormous. The surgical treatment of these psychiatric disorders, although potentially valuable, remains one of the most controversial subjects in medicine, as its concept and potential reality raises thorny issues of moral, ethical, and socioeconomic consequence. This article traces the roots of concept and surgical efforts in this turbulent area from prehistory to the 21st century. The details of the late 19th and 20th century evolution of approaches to the problem of intractable psychiatric diseases with scrutiny of the persona and contributions of the key individuals Gottlieb Burckhardt, John Fulton, Egas Moniz, Walter Freeman, James Watts, and William Scoville are presented as a foundation for the later, more logically refined approaches of Lars Leksell, Peter Lindstrom, Geoffrey Knight, Jean Talaraich, and Desmond Kelly. These refinements, characterized by progressive minimalism and founded on a better comprehension of underlying pathways of normal function and disease states, have been further explored with recent advances in imaging, which have allowed the emergence of less invasive and technology driven non-ablative surgical directives toward these problematical disorders of mind and mood. The application of therapies based on imaging comprehension of pathway and relay abnormalities, along with explorations of the notion of surgical minimalism, promise to serve as an impetus for revival of an active surgical effort in this key global health and socioeconomic problem. Eventual coupling of cellular and molecular biology and nanotechnology with surgical enterprise is on the horizon.

The emerging future of cerebral surgery will witness the refined evolution of current techniques, as well as the introduction of numerous novel concepts. Clinical practice and basic science research will benefit greatly from their application. The sum of these efforts will result in continued minimalism and improved accuracy and efficiency of neurosurgical diagnostic and therapeutic methodologies.Initially, the refinement of current technologies will further enhance various aspects of cerebral surgery. Advances in computing power and information technology will speed data acquisition, storage, and transfer. Miniaturization of current devices will impact diverse areas, such as modulation of endoscopy and endovascular techniques. The increased penetrance of surgical technologies such as stereotactic radiosurgery, neuronavigation, intraoperative imaging, and implantable electrodes for neurodegenerative disorders and epilepsy will enhance the knowledge and experience in these areas and facilitate refinements and advances in these technologies. Further into the future, technologies that are currently relatively remote to surgical events will fundamentally alter the complexity and scale at which a neurological disease may be treated or investigated. Seemingly futuristic concepts will become ubiquitous in the daily experience of the neurosurgeon. These include diverse fields such as nanotechnology, virtual reality, and robotics. Ultimately, combining advances in multiple fields will yield progress in diverse realms such as brain tumor therapy, neuromodulation for psychiatric diseases, and neuroprosthetics. Operating room equipment and design will benefit from each of the aforementioned advances. In this work, we discuss new developments in three parts. In Part I, concepts in minimalism important for future cerebral surgery are discussed. These include concrete and abstract ideas in miniaturization, as well as recent and future work in microelectromechanical systems and nanotechnology. Part II presents advances in computational sciences and technological fields dependent on these developments. Future breakthroughs in the components of the "computer," including data storage, electrical circuitry, and computing hardware and techniques, are discussed. Additionally, important concepts in the refinement of virtual environments and the brain-machine interface are presented, as their incorporation into cerebral surgery is closely linked to advances in computing and electronics. Finally, Part III offers insights into the future evolution of surgical and nonsurgical diagnostic and therapeutic modalities that are important for the future cerebral surgeon. A number of topics relevant to cerebral surgery are discussed, including the operative environment, imaging technologies, endoscopy, robotics, neuromodulation, stem cell therapy, radiosurgery, and technical methods of restoration of neural function. Cerebral surgery in the near and distant future will reflect the application of these emerging technologies. As this article indicates, the key to maximizing the impact of these advancements in the clinical arena is continued collaboration between scientists and neurosurgeons, as well as the emergence of a neurosurgeon whose scientific grounding and technical focus are far removed from those of his predecessors.

On 27 May 1999, a big brown bat (Eptesicus fuscus) was discovered on an island exhibit at the Denver Zoo that contained a troop of 15 hooded capuchin monkeys (Cebus apella cay). The monkeys were attacking the bat when it was discovered. The bat was collected and humanely euthanatized without direct handling and submitted to the Colorado Department of Public Health and Environment Virology Laboratory for rabies evaluation. The monkeys had not been vaccinated against rabies virus. The next day, the laboratory confirmed that the bat was positive for rabies. The recommendations from the Colorado Department of Public Health and Environment and the Centers for Disease Control and Prevention were to euthanatize the monkeys or quarantine them and comply with the human nonvaccinated postexposure protocol. A 1-ml dose of a killed rabies vaccine was administered i.m. in the hip on each of days 2, 7, 12, 19, and 33 postexposure, and a single dose of human rabies immune globulin was administered i.m. 5 days postexposure. Blood was collected under anesthesia in order to evaluate the immune response after rabies vaccination from six monkeys 5 days postexposure, six monkeys 19 days postexposure (five of the six monkeys were the same monkeys bled 5 days postexposure), 15 monkeys 67 days postexposure, and 13 monkeys approximately 1 yr postexposure. All of the monkeys developed and maintained levels of rabies virus neutralizing antibody above 0.05 IU/ml by 67 days postexposure. Although a serologic titer of 0.05 IU/ml indicates an adequate human response after rabies vaccination, no similar information is available for nonhuman primates. To date, none of the monkeys has succumbed to rabies.

Background: Shoulder hemorrhage resulting in brachial plexus neuropathy is a rare occurrence most often seen in cases of traumatic injury or anticoagulation therapy. We report a unique case of spontaneous brachial plexus hemorrhage., Case Description: This is the first report of a spontaneous shoulder hemorrhage in which a 48-year-old jackhammer operator presented to the emergency department with a sudden onset of right shoulder pain and upper extremity pain and numbness. Imaging studies revealed a hematoma in the right axilla and chest wall. Without evidence of active bleeding or worsening neurologic deficit, this patient was treated conservatively with pain control and observation and eventually experienced a full recovery. Had there been persistent neurologic deficit, however, surgical evacuation would have been indicated., Conclusions: Cases of nerve compression caused by a hematoma should be analyzed on the basis of the severity of the neurologic deficit and not on the underlying cause of bleeding. Conservative treatment may be indicated in cases of mild or improving neurologic deficit, but regardless of its etiology, a hematoma that results in severe or worsening neurologic symptoms must be surgically evacuated to prevent permanent nerve damage.
