During the initial stages of eye development, optic vesicles grow laterally outward from both sides of the forebrain and come into contact with the surrounding surface ectoderm (SE). Within the region of contact, these layers then thicken locally to create placodes and invaginate to form the optic cup (primitive retina) and lens vesicle (LV), respectively. This paper examines the biophysical mechanisms involved in LV formation, which consists of three phases: (1) lens placode formation; (2) invagination to create the lens pit (LP); and (3) closure to form a complete ellipsoidally shaped LV...

Sarah Ackerman
This paper takes up Romain Rolland's description of a nearly universal "oceanic feeling" and considers Freud's avowed disinterest in this concept. Herman Melville elaborates and expands the concept of the oceanic in the text of Moby Dick, juxtaposing Ishmael's oceanic reverie while up high on the masthead with Ahab's focused determination to destroy Moby Dick. Melville's extension of the concept recasts the oceanic as an aspect of Freud's recommendations about the necessary conditions for psychoanalytic process, inviting a comparison of going to sea with going into analysis...

Near-infrared spectroscopy (NIRS) has been used effectively post-cardiac-arrest to gauge adequacy of resuscitation and predict the likelihood of achieving a return of spontaneous circulation. However, preempting hemodynamic collapse is preferable to achieving ROSC through advanced cardiac life support. Minimizing "time down" without end-organ perfusion has always been a central pillar of ACLS. In many critically ill patients there is a prolonged phase of end-organ hypoperfusion preceding loss of palpable pulses and initiation of ACLS...

BACKGROUND: Trauma is the leading nonobstetric cause of death in women of reproductive age, and pregnant women in particular may be at increased risk of violent trauma. Management of trauma in pregnancy is complicated by altered maternal physiology, provider expertise, potential disparate imaging, and distorted anatomy. Little is known about the impact of trauma on maternal mortality. OBJECTIVE: We sought to: (1) characterize nonviolent and violent trauma among pregnant women; (2) determine whether pregnancy is associated with increased mortality following traumatic injury; and (3) identify risk factors for trauma-related death in pregnant women...

Homicide, suicide, and substance abuse accounted for nearly one fourth of all pregnancy-associated deaths in Illinois from 2002 through 2013. Maternal mortality review in Illinois has been primarily focused on obstetric and medical causes and little is known about the circumstances surrounding deaths due to homicide, suicide, and substance abuse, if they are pregnancy related, and if the deaths are potentially preventable. To address this issue, we implemented a process to form a second statewide maternal mortality review committee for deaths due to violence in late 2014...

INTRODUCTION: Despite the recent promotion of communication guides to improve decision-making with patients nearing the end of their lives, these conversations remain challenging. Deeper and more comprehensive understanding of communication barriers that undermine discussions and decisions with patients at risk of dying from heart failure (HF) are vital for informing communication in healthcare. OBJECTIVES: To explore experiences and perspectives of patients with advanced HF, their caregivers and providers, regarding conversations for patients at risk of dying from HF...

Cutaneous eruptions are among the most common immune-related adverse events (irAEs) associated with anti-programmed cell death protein 1/programmed cell death ligand 1 therapy, and are often clinically and histologically characterized as lichenoid. Nonlichenoid patterns may also occur and are likely to be encountered by surgical pathologists, given the increasing clinical use of these agents. The purpose of this study is to describe the histopathologic features of nonlichenoid cutaneous irAEs from patients receiving anti-programmed cell death protein 1/programmed cell death ligand 1 therapies for a variety of underlying advanced malignancies...

Loss-of-function mutations in SCN1A cause Dravet syndrome (DS), a catastrophic childhood epilepsy in which patients experience comorbid behavioral conditions, including movement disorders, sleep abnormalities, anxiety, and intellectual disability. To study the functional consequences of voltage-gated sodium channel mutations, we use zebrafish with a loss-of-function mutation in scn1lab, a zebrafish homolog of human SCN1A. Homozygous scn1lab(s552/s552) mutants exhibit early-life seizures, metabolic deficits, and early death...

BACKGROUND AND PURPOSE: Flow diverters are emerging as an endovascular treatment alternative for proximally located intracranial aneurysms. However, treatment of aneurysms at and beyond the circle of Willis is not well-established. We assessed the clinical safety and efficacy of the Flow Re-Direction Endoluminal Device Jr (FRED Jr) dedicated to small-vessel diameters between 2.0 and 3.0 mm. MATERIALS AND METHODS: This was a multicenter observational clinical study of 42 patients with 47 aneurysms treated by a flow-direction technique with the FRED Jr...

Marfan syndrome (MFS) is a connective tissue disorder, in which aortic rupture is the major cause of death. MFS patients with an aortic diameter below the advised limit for prophylactic surgery (<5cm) may unexpectedly experience an aortic dissection or rupture, despite yearly monitoring. Hence, there is a clear need for improved prognostic markers to predict such aortic events. We hypothesize that elastin fragments play a causal role in aortic calcification in MFS and that microcalcification serves as a marker for aortic disease severity...

INTRODUCTION: In 2013, 55,000 infants and children, aged 0 to 14, died in the United States. Nearly 7,000 of those deaths were attributed to traumatic causes. A child's death significantly affects emergency service personnel (ESP) caring for children and families. This study explores the lived experience of ESP involved in unsuccessful pediatric resuscitation efforts and how this experience affects them professionally and personally. METHODS: A phenomenologic approach guided this study...

OBJECTIVE: Opioid abuse has become an epidemic in the United States, causing nearly 50,000 deaths a year. Postoperative pain is an unavoidable consequence of most surgery, and surgeons must balance the need for sufficient analgesia with the risks of overprescribing. Prescribing narcotics is often the responsibility of surgical residents, yet little is known about their opioid-prescribing habits, influences, and training experience. DESIGN: Anonymous online survey that assessed the amounts of postoperative opioid prescribed by residents, including type of analgesia, dosage, and number of pills, for a series of common general surgery procedures...

BACKGROUND Splenic injury is the leading cause of major bleeding after blunt abdominal trauma. We examined the clinical and radiological presentations, management, and outcome of blunt splenic injuries (BSI) in our institution. MATERIAL AND METHODS A retrospective study of BSI patients between 2011 and 2014 was conducted. We analyzed and compared management and outcome of different splenic injury grades in trauma patients. RESULTS A total of 191 BSI patients were identified with a mean (SD) age of 26.9 years (13...

BACKGROUND: Neonatal mortality accounts for nearly three quarters of all infant deaths in Vietnam. The nursing team are the largest professional group working with newborns, however do not routinely receive neonatal training and there is a lack of research into the impact of educational provision. This study explored changes in nursing perceptions towards their role following a neonatal educational intervention. Parents perceptions of nursing care were explored to determine any changes as nurses gained more experience...

Memories of Near-Death Experiences (NDEs) seem to be very detailed and stable over time. At present, there is still no satisfactory explanation for the NDEs' rich phenomenology. Here we compared phenomenological characteristics of NDE memories with the reported experience's intensity. We included 152 individuals with a self-reported "classical" NDE (i.e. occurring in life-threatening conditions). All participants completed a mailed questionnaire that included a measure of phenomenological characteristics of memories (the Memory Characteristics Questionnaire; MCQ) and a measure of NDE's intensity (the Greyson NDE scale)...

BACKGROUND: Latinos born in the US, 36 million, comprise 65% of all US Latinos. Yet their cancer experience is nearly always analyzed together with their foreign-born counterparts, 19 million, who constitute a steady influx of truly lower-risk populations from abroad. To highlight specific cancer vulnerabilities for US-born Latinos, we compare their cancer mortality to the majority non-Latino white (NLW) population, foreign-born Latinos, and non-Latino blacks. METHODS: We analyzed 465,751 cancer deaths from 2008 to 2012 occurring among residents of California and Texas, the two most populous states, accounting for 47% of US Latinos...
