Abstract
ABSTRACT The COVID-19 pandemic impacted the mental health and educational experiences of nursing students in undergraduate and graduate programs. A larger mixed-methods study aimed to understand how COVID-19 impacted personal lives and learning experiences of students across all programs levels. This article reports on qualitative data obtained from focus groups organized by student program level. Six themes emerged, including fear and uncertainty, trust in God, educational and career concerns, concerns about family, mental health issues, and isolation/lack of human touch. Key areas covered are the emotional and psychological effects of COVID-19 and its factors and the role of faith during COVID-19 among nursing students.

Abstract
ABSTRACT The COVID-19 pandemic rapidly transformed nursing education, creating multiple stressors for students. The researchers in this study examined how undergraduate and graduate nursing students at a faith-based university perceived the impact of COVID-19. A multiple linear regression model explored the effect of 17 variables on the Impact of Events Scale-Revised (IES-R) scores. Anxiety level, quality of sleep, and perceived health demonstrated a statistically significant influence on IES-R scores; 27% of students had IES-R scores above 33, indicating high risk for posttraumatic stress disorder. Strategies to help address student stress and anxiety are discussed.

Abstract
Purpose of study: The need for forgiveness education for nursing self-care and forgiveness facilitation has risen. Therefore, the present pilot study tested the efficacy of an 8-week forgiveness bibliotherapy with a small number of undergraduate nursing students. Design of study: Matched pairs of nursing students were randomly assigned to either the experimental group or no-contact control group. The experimental group, using 8 keys to forgiveness by R. Enright (2015) as the treatment manual, read one chapter a week for 8 weeks and provided weekly reflections. Forgiveness and forgiveness-related outcome measures were administered at pretest, posttest, and one-month follow-up. Findings: At the posttest, the experimental group had significantly greater improvement in forgiveness compared to the control group with a large effect size, which was maintained at one month follow-up. There was no other significant difference between the two groups. Within-group comparisons of the experimental group showed improvement in forgiveness, anxiety, depression, and fatigue from pre to post testing periods and forgiveness, anger, anxiety, depression, and fatigue from pre to follow-up testing periods. Conclusion: Use of bibliotherapy may be a cost-effective way to promote the virtue of forgiveness for students in nursing programs.

Abstract
The Helping Babies Breathe (HBB) training program trains providers in effective resuscitation of infants in developing countries. This study evaluated the effectiveness of the HBB training program on midwives' knowledge and skills in Northern Jordan. Using a nonequivalent control group design, 50 midwives (control, n = 25; experimental, n = 25) from 3 public hospitals in Northern Jordan were recruited and their knowledge and skills were evaluated before and after the training. The program has 3 aspects: 2 hours of teaching, 1 hour of testing, and 25 minutes of skills assessment per participant. The skills were tested individually for each participant, and they were reevaluated at 8 months after. The control and experimental groups significantly differed in posttest scores on knowledge, Objective Structured Clinical Examination A and B skills, and bag-mask application after adjusting for covariates. The HBB training program significantly enhanced knowledge of midwives in the experimental group (P < .05) and demonstrated skills. The HBB training program was helpful in improving midwives' knowledge and practices on immediate care of a newborn baby. Therefore, training midwives using the HBB training program can improve their knowledge and skills and thereby improve infant outcomes in Jordan.

Abstract
The diagnosis of childhood cancer is one of the most serious and unexpected experiences a mother can endure. A descriptive phenomenological approach was used to explore the experiences of mothers of children diagnosed with cancer in Jordan. Themes that emerged include (1) Emotional response on knowing the diagnosis (feelings of shock, lack of preparedness, denial, and feelings of "paralysis"), (2) Fear of the dreaded disease (fear of suffering and fear of death), and (3) The challenges of the treatment journey (inadequate financial resources, role transition, and feeling socially isolated). This study describes the experiences of Jordanian mothers who care for their children diagnosed with cancer so that health care providers can develop strategies to provide adequate psychological support to these mothers.

Abstract
Aim To investigate the knowledge and practice of physical restraints (PR) among Jordanian intensive care unit (ICU) nurses. Design A descriptive, observational design was used. Methods A convenience sampling was used to recruit participants. We examined the knowledge of PR in 301 nurses (knowledge check) and the real-time practice of PR in 81 nurses (direct observation) in ICU. A knowledge questionnaire was used to collect data on knowledge about PR use, and data on their practice of PR were observed and documented using an observation checklist. Results The mean scores of nurses' knowledge and practices were 61.5 (SD = 12.1) and 57.4 (SD = 9.7), respectively. More than half of nurses had poor knowledge of PR use and incorrect practice of implementing PR (51.5% and 60.5%, respectively). Results indicated a positive correlation between nurses' knowledge and their use of PR.

Abstract
INTRODUCTION Parenting a child diagnosed with autism spectrum disorder (ASD) is challenging for mothers because of concerns related to behavior, difficulties in accessing specialized care, and lack of community acceptance, yet their stories in Jordanian context are still unknown. Common challenges in Jordan include financial burdens, lack of public awareness, and lack of specialized knowledge even among health care providers, which may lead to delays in obtaining the diagnosis and interventions for ASD. METHOD A phenomenological descriptive approach was used to explore and understand the mothers' everyday lived experiences of raising a child with ASD. Semistructured interviews were conducted with 14 mothers to identify their challenges so that nurses can identify gaps in services, empower families, and facilitate optimum care to these Jordanian families. FINDINGS The main themes that emerged were (1) mothers' journeys with the diagnosis, in which mothers recognized the abnormalities of their children, reported delays in getting the diagnosis and initiation of treatment, and described a wide range of reactions to the diagnosis from grief and guilt to a blessing from God; (2) the burden of care, by which mothers reported physical and emotional exhaustion, financial burdens, and concerns about the quality of available services; and (3) the consequences and the hurdle of having a child with ASD, which affected the family relationships and social life. DISCUSSION Jordanian mothers caring for children with ASD face several challenges, including physical, psychological, financial, and social challenges, in addition to limited specialized services. Identifying their unique challenges and needs are essential to support them, provide appropriate services and resources, and develop policies and guidelines for culturally competent quality services.

Abstract
PURPOSE To explore the relationships between stress, coping, duration of tracheostomy, and quality of life (QOL) of parental caregivers who care for a child with a tracheostomy at home. DESIGN A cross-sectional correlational design was used to study parents who care for a child with a tracheostomy at home. Family Inventory of Life Events, Family Crisis Oriented Personal Evaluation Scale, and Psychological General Well-Being Index were used to measure stress, coping, and QOL, respectively. Data were collected using both online and paper-pencil format. MAIN OUTCOME VARIABLE quality of life. RESULTS Parents who care for their infants/toddlers with a tracheostomy at home were found to be in moderate distress. Mean age of the participants was 33 years (N = 71), and the average duration of the child's tracheotomy was 18.22 (SD = 9.59) months. Multivariate analysis showed a significant inverse relationship between QOL and stress. QOL was significantly associated with coping, B = 19.91, β = .43, p <.001.

Abstract
Assistive reproductive technology has progressed significantly over the past few decades. In spite of the advances, people may still resort to a surrogate for bearing and birthing a baby. Surrogacy, though an altruistic act, has been commercialized in the past few years, leading to emergence of several ethico-legal concerns. Nurses care for the surrogates, the infants, and the intended parents through their journey with sensitivity, advocacy, compassion, and confidentiality. This article intends to explore the implications of surrogacy to individuals, families, nations, and health care.

Abstract
PURPOSE Currently, there is a lack of evidence-based guidelines on the proper protocol for feeding infants with a tracheostomy in the neonatal intensive care unit (NICU). The purpose of this study was to provide preliminary insight into the outcomes of these infants in one mid-Atlantic pediatric hospital. DESIGN AND METHODS Retrospective and descriptive. The study team reviewed 114 patient records, 42 of which met the inclusion criteria. Data were organized based on: 1) general demographics and history; b) feeding-related variables at multiple points; c) speech-related variables, including assessments and swallowing studies; d) respiratory variables at multiple points; and, e) discharge data. Other variables included birth-related information, ventilation settings and feeding modifications. RESULTS Infants were placed into three groups at discharge based on feeding outcomes. Forty-three percent were discharged on full oral feeds, 38% on combined oral and gavage, and 19% of infants were discharged on full gavage feeds. Informal analysis showed that all three categories of infants gained weight during hospitalization, different PEEP pressures and different lengths of hospitalization were observed among the groups, and infant characteristics (e.g., APGAR, gestational ages) were similar across groups. CONCLUSIONS Overall results provide insight into factors that may be predictive of feeding status at discharge for infants with a tracheostomy in an NICU. PRACTICAL IMPLICATIONS Results of this study can provide important insight into the feeding outcomes of infants in a NICU with a tracheostomy and can hopefully lead to additional research to help determine the most efficacious procedures for feeding this patient population.

Abstract
Worldwide, about 15 million infants are born prematurely each year. Technological advances, including invasive mechanical ventilation, play a major role in the survival of extremely preterm babies. Those who survive may have prolonged morbid conditions that result in long-term sequelae. Nurses face several challenges during the hospitalization of these infants. Vigilant care, monitoring, and careful handling of the infants can prevent infections and long-term complications. Newer, less invasive technologies are promising for improved outcomes in extremely preterm infants.

Abstract
Transitioning the care of a previously critically ill infant to home poses many challenges for the parents. Prior to the infant's discharge, the parents undergo rigorous training to continue the care of their infants at home. Even after training, parents may feel overwhelmed by the thought of managing an emergency at home. This evidence-based practice project aims to provide parents with additional hands-on practice of cardiopulmonary resuscitation (CPR) prior to their infant's discharge. Based on this project, a program of teaching CPR regularly is established currently in the NICU at Nemours Alfred I. duPont Hospital for Children.

Abstract
BACKGROUND Subglottic stenosis (SGS) is the most common congenital and/or acquired laryngotracheal anomaly requiring tracheotomy in infants. We sought to determine factors associated with a greater likelihood of tracheotomy in symptomatic infants with SGS who underwent laryngotracheoplasty (LTP). METHODS Retrospective case series with chart review of patients undergoing single-stage LTP for SGS over a 10-year period (2001-2010) in a tertiary-care pediatric hospital. RESULTS Twenty-two children (15 boys, 7 girls), with a mean gestational age of 32.5weeks, underwent LTP with and without interpositional grafting, at a median age of 89days. Ten patients (43%) required postoperative tracheotomy. Of patients weighing <2.5kg, 7 of 8 eventually required tracheotomy, while none weighing >5kg needed tracheotomy (p=0.003). The average length of stay for patients with a tracheotomy was 125days, while those without tracheotomy required only 58days (p=0.011). The grade of SGS (p=0.809), gender (p=0.968), age at surgery (p=0.178), and gestational age (p=0.117) were not significantly associated with the need for tracheotomy. Weight at surgery was significantly correlated with the likelihood of needing tracheotomy (p=0.003). CONCLUSIONS Patients who weighed less than 2.5kg at the time of LTP procedures were more likely to require a postoperative tracheotomy. Children who required tracheotomy had longer lengths of hospital stay.

Abstract
Children with tracheostomies are increasingly discharged home for continued care by their parents. Nurses are responsible for providing these parents with the extensive education required for a smooth and successful transition to home care. This article is intended to help neonatal and pediatric nurses to effectively prepare the parents of an infant with a tracheostomy to provide safe, quality care to their child after being discharged from an acute care setting to their home. This article discusses the knowledge, attitudes, and skills the parents are required to acquire prior to the infant's discharge. Home ventilation, airway management, suctioning, tracheostomy care, emergency management, safe home environment, equipment for continuous or intermittent ventilation, and supplies necessary for care are some of the topics discussed.

Abstract
The purpose of this study was to identify and measure components of perceived stress in fathers of infants in a surgical neonatal intensive care unit (NICU). The Parent Stressor Scale: Infant Hospitalization (PSS:IH) was used to assess perceived stress in 22 fathers. Paternal stress was highest in the domains of "Parental Role Alteration" and "Infant Appearance and Behavior." "Sights and Sounds" did not appear to be associated with self-reported stress. This study demonstrates elevated levels of perceived stress among fathers of surgical NICU babies. Attention to fathers may be assisted by findings.

Abstract
Constitutive expression of the cold-regulated COR15a gene of Arabidopsis thaliana results in a significant increase in the survival of isolated protoplasts frozen over the range of -4.5 to -7 degreesC. The increased freezing tolerance is the result of a decreased incidence of freeze-induced lamellar-to-hexagonal II phase transitions that occur in regions where the plasma membrane is brought into close apposition with the chloroplast envelope as a result of freeze-induced dehydration. Moreover, the mature polypeptide encoded by this gene, COR15am, increases the lamellar-to-hexagonal II phase transition temperature of dioleoylphosphatidylethanolamine and promotes formation of the lamellar phase in a lipid mixture composed of the major lipid species that comprise the chloroplast envelope. We propose that COR15am, which is located in the chloroplast stroma, defers freeze-induced formation of the hexagonal II phase to lower temperatures (lower hydrations) by altering the intrinsic curvature of the inner membrane of the chloroplast envelope.

Abstract
BACKGROUND Mutations in the human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) gene confer resistance to antiviral drugs acting on RT. Current methods employed to detect such resistance require time-consuming culture techniques during which selective pressures may affect the outcome of the test. OBJECTIVES We sought to determine whether drug-susceptible and drug-resistant HIV-1 derived from clinical specimens could be distinguished by the effects of the active form of the drug on the enzyme activity in a quantitative, cell-free RT assay. STUDY DESIGN Polyethylene glycol (PEG)-precipitated virus was obtained from 7-day culture supernatants. RT activity in the lysed viral extracts was measured in the presence of increasing concentrations of the active form of the drug being tested. IC50 (50% inhibitory concentration) values were determined by application of the median effect equation. RESULTS Assays from nine post-nevirapine therapy isolates gave IC50 values at least 2 logs greater than pre-nevirapine isolates. The method also correctly distinguished between isolates sensitive and resistant to 2',3'-dideoxyinosine (ddI), but not between the ZDV-sensitive and ZDV-resistant isolates tested. The results agreed with data obtained by sequencing and by culture-based susceptibility assays.

Abstract
Visualization of arteries using intravenous injections of contrast material requires an imaging system capable of (a) excellent sensitivity to dilute concentrations of contrast media and (b) adequate temporal resolution to minimize the effects of motion during the exposure. A line-scanned radiography system based on a CT fan-beam detector (high-pressure xenon ionization chamber) was used for phantom and animal studies of intravenous arteriography to demonstrate the potential advantages of this method. Even though line-scanned systems require long scan times compared to existing radiographic methods, they are capable of showing rapidly moving arteries without blurring. Concentrations of 3 mg/ml of iodine could be seen in vessels 2 mm in diameter. Phantom studies using kVp switching showed that bone or soft tissue could be selectively cancelled.
