RESUMEN

AIMS: (a) Quantify frequency of patient moves within a NICU with single patient and semi-private rooms (SPR). (b) Compare staff and parent perceptions of these moves. METHODS: A hospital administrative database was evaluated to quantify the frequency of moves. A Room Change Questionnaire was devised to evaluate perceptions from NICU families and staff. RESULTS: Most families reported experiencing at least 1 patient move (92 percent), with the majority reporting at least 3 moves (58 percent). Staff perceived moves as negative significantly more than parents (p < .01), and overreported negative family perceptions (p < .01). Overall, moves did not bother families (52 percent); however, most families who moved 3 or more times reported at least 1 negative perception (63 percent). CONCLUSION: SFRs increase the number of patient moves. NICU staff's perception is significantly more negative than family's perception; however, most families who were moved frequently reported at least 1 negative perception.

RESUMEN

BACKGROUND: The incidence of tongue cancer in young adults is on the rise. This trend is more pronounced in females. Although the aetiology is still unclear, there is mounting evidence that genetic syndromes can play a key role in development of oral cancers in this patient group. We report the first case of oral squamous cell carcinoma (oSCC) in a young adult with an MYH9-related disorder (MYH9-RD). CASE PRESENTATION: A 19-year-old female with a germline MYH9 variant (missense variant in exon 2: c.287C > T, (p.Ser96Leu)) was referred to the head and neck surgery department for investigation of a painful, thick right tongue ulcer. She was diagnosed with Epstein syndrome, an MYH9-RD, at 12 years of age. Her main phenotypic features were profound thrombocytopenia and marked renal impairment. The tongue biopsy confirmed SCC. Preoperative positron emission tomography (PET) revealed avidity in the right tongue and ipsilateral level 2A neck lymph node. With substantial preoperative multidisciplinary input, she underwent cancer ablation and microvascular free flap reconstruction. Her pathology showed a 35 mm diameter, 14 mm thick moderately differentiated SCC with perineural and lymphovascular invasion. Two out of 38 right neck nodes were positive for metastasis with extranodal extension. None of the 34 left neck nodes was involved. She had an uneventful recovery and was discharged home on day 6 postoperative day. On day 15 postoperative day, she had catastrophic bleeding in the neck with a respiratory arrest after a forceful cough. She required an emergency tracheostomy and returned to the theatre for haemostasis. Following a short inpatient stay, she was again discharged home and underwent adjuvant therapy consisting of external beam radiotherapy of 60Gy in 30 fractions. On clinical examination and PET at 6 months after surgery, she had no evidence of disease recurrence. CONCLUSIONS: MYH9-RD can present with advanced locoregional oral cavity malignancy at an early age. The combination of profound thrombocytopenia and marked renal impairment can impact heavily on routine major head and neck cancer surgery and adjuvant treatment. This rare and challenging condition underlines the importance of early detection of cancer and multidisciplinary team input.

RESUMEN

Introduction: The majority of people diagnosed with MS are of childbearing or child fathering age, therefore family planning is an important issue for both women and men with MS. Fertility and the course of pregnancy are not affected by MS; however, people with MS (pwMS) may have concerns that there will be a greater risk of complications to the mother and/or adverse pregnancy outcomes either due to the disease or to ongoing medication. This survey aimed to understand family planning decision making in pwMS and related unmet educational needs. Methods: A total of 332 pwMS across the USA, UK, France, Germany, Italy, and Spain were recruited from a specialist patient panel agency to participate in a smartphone-enabled standing panel. The 80-question survey focussed on decision making and information sources for pwMS regarding family planning, as well as behavior during and after pregnancy. Male patients with MS did not respond to specific questions on pregnancy. Survey results were directly compared with the 2016 US and 2010 UN census data. Results: pwMS were more likely to have no children than the general population, particularly in the subgroup of patients aged 36-45 years. A total of 56% of pwMS reported that the disease affected, with different degrees of impact, their family planning decision making. Of these, 21% significantly changed their plans for timing of pregnancy and the number of children, and 14% decided against having children. Participants indicated that healthcare professionals were the primary source of information on family planning (81% of responses). The timing of planned pregnancy was not considered when selecting treatment by 78% of participants. Conclusion: MS was found to significantly impact family planning decision making, with pwMS significantly less likely to have children in comparison with the general population.

RESUMEN

In the melanocortin pathway, melanocortin-4 receptor (MC4R) functions to control energy homeostasis. MC4R is expressed in a sub-population of Sim1 neurons (Sim1/MC4R neurons) and functions in hypothalamic paraventricular nuclei (PVN) to control food intake. Mapping sites of hypothalamic injury in obesity is essential to counteract the disease. In the PVN of male and female mice with diet-induced obesity (DIO) there is neuronal loss. However, the existing subpopulation of PVN Sim1/MC4R neurons is unchanged, but has a loss of mitochondria and MC4R protein. In mice of both sexes with DIO, dietary intervention to re-establish normal weight restores abundance of MC4R protein in Sim1/MC4R neurons and neurogenesis in the PVN. However, the number of non-Sim1/MC4R neurons in the PVN continues to remain decreased. Selective survival and recovery of Sim1/MC4R neurons after DIO suggests these neurons as preferential target to restore energy homeostasis and of therapy against obesity.

RESUMEN

Genetic obesity increases in liver phosphatidylcholine (PC)/phosphatidylethanolamine (PE) ratio, inducing endoplasmic reticulum (ER) stress without concomitant increase of ER chaperones. Here, it is found that exposing mice to a palm oil-based high fat (HF) diet induced obesity, loss of liver PE, and loss of the ER chaperone Grp78/BiP in pericentral hepatocytes. In Hepa1-6 cells treated with elevated concentration of palmitate to model lipid stress, Grp78/BiP mRNA was increased, indicating onset of stress-induced Unfolded Protein Response (UPR), but Grp78/BiP protein abundance was nevertheless decreased. Exposure to elevated palmitate also induced in hepatoma cells decreased membrane glycosylation, nuclear translocation of pro-apoptotic C/EBP-homologous-protein-10 (CHOP), expansion of ER-derived quality control compartment (ERQC), loss of mitochondrial membrane potential (MMP), and decreased oxidative phosphorylation. When PE was delivered to Hepa1-6 cells exposed to elevated palmitate, effects by elevated palmitate to decrease Grp78/BiP protein abundance and suppress membrane glycosylation were blunted. Delivery of PE to Hepa1-6 cells treated with elevated palmitate also blunted expansion of ERQC, decreased nuclear translocation of CHOP and lowered abundance of reactive oxygen species (ROS). Instead, delivery of the chemical chaperone 4-phenyl-butyrate (PBA) to Hepa1-6 cells treated with elevated palmitate, while increasing abundance of Grp78/BiP protein and restoring membrane glycosylation, also increased ERQC, expression and nuclear translocation of CHOP, non-mitochondrial oxygen consumption, and generation of ROS. Data indicate that delivery of PE to hepatoma cells under lipid stress recovers cell function by targeting the secretory pathway and by blunting pro-apoptotic branches of the UPR.

RESUMEN

PURPOSE: The American Society of PeriAnesthesia Nurses (ASPAN) is responsible for establishing evidence-based standards to guide perianesthesia nursing practice. The ASPAN model for evidence-based practice acknowledges the potential for the Delphi technique to identify priorities for perianesthesia research. The purpose of this Delphi study was to generate a consensus on pain and comfort among a panel of experts. DESIGN: ASPAN convened a panel of experts to provide recommendations based on seven categories, this led to the development of a questionnaire to build consensus. METHODS: Survey conducted among panel of experts to obtain consensus. Two survey rounds were completed. FINDINGS: A consensus was obtained reaching a 70% benchmark for an acceptance. CONCLUSIONS: The results found a consensus on topics required for education and competency among perianesthesia nurses including transfer and discharge criteria related to pain and comfort, resources for perianesthesia nurses, policy guidelines, and the management of the special needs of perianesthesia patients.

RESUMEN

The hypothalamus is essential for regulation of energy homeostasis and metabolism. Feeding hypercaloric, high-fat (HF) diet induces hypothalamic arcuate nucleus injury and alters metabolism more severely in male than in female mice. The site(s) and extent of hypothalamic injury in male and female mice are not completely understood. In the paraventricular nucleus (PVN) of the hypothalamus, single-minded family basic helix-loop helix transcription factor 1 (Sim1) neurons are essential to control energy homeostasis. We tested the hypothesis that exposure to HF diet induces injury to Sim1 neurons in the PVN of male and female mice. Mice expressing membrane-bound enhanced green fluorescent protein (mEGFP) in Sim1 neurons (Sim1-Cre:Rosa-mEGFP mice) were generated to visualize the effects of exposure to HF diet on these neurons. Male and female Sim1-Cre:Rosa-mEGFP mice exposed to HF diet had increased weight, hyperleptinemia, and developed hepatosteatosis. In male and female mice exposed to HF diet, expression of mEGFP was reduced by > 40% in Sim1 neurons of the PVN, an effect paralleled by cell apoptosis and neuronal loss, but not by microgliosis. In the arcuate nucleus of the Sim1-Cre:Rosa-mEGFP male mice, there was decreased alpha-melanocyte-stimulating hormone in proopiomelanocortin neurons projecting to the PVN, with increased cell apoptosis, neuronal loss, and microgliosis. These defects were undetectable in the arcuate nucleus of female mice exposed to the HF diet. Thus, injury to Sim1 neurons of the PVN is a shared feature of exposure to HF diet in mice of both sexes, while injury to proopiomelanocortin neurons in arcuate nucleus is specific to male mice.

RESUMEN

AIM: Approximately 20-30% of children/adolescents with cancer will not respond to standard therapies. These children are usually offered experimental treatment in the form of an early-phase clinical trial. We examined the perspectives of health-care professionals (HCPs) regarding obtaining informed consent for early-phase trials in paediatric oncology. METHODS: We collected survey data from 87 HCPs working in paediatric cancer centres across Australia and New Zealand. RESULTS: HCPs were, on average, 44 years old (range = 25-74), with 15.8 years' experience in paediatric oncology (range = 1-40). Few HCPs (17.4%) received training for early-phase trial consent; however, most were willing to attend training (77.9%). HCPs (61.6%) reported that they informed families about early-phase trials without any attempt to influence their decision. However, 23.3% of HCPs reported that they informed families that their child would benefit. HCPs' main obstacle in obtaining consent was their perception of parents' eagerness to 'try anything' (52.3%). HCPs perceived that many parents misunderstood key clinical trials concepts, with 25.2% of HCPs believing that not being given clear information influenced parents' decisions. Physicians were more likely than social workers/nurses to inform families that other children will benefit from enrolment in the study. Social workers/nurses appeared to rate the chance of benefits for the patient higher than physicians. CONCLUSIONS: HCPs may experience difficulty conducting early-phase trial consultations and obtaining valid informed consent. Our study highlights the need for formal training for HCPs and additional patient education tools.

RESUMEN

Nursing students traditionally find bioscience difficult and anxiety provoking. This has important ramifications, as anxiety can hinder comprehension and lead to poor exam performance. The aim of the present study was to assess whether there was any difference between the anxiety levels of nursing students during their bioscience laboratory classes compared to their clinical laboratory classes. Students were recruited from a first year Bachelor of Nursing program. The self-report State-Trait Anxiety Inventory (short form) was administered at the start of all classes throughout the semester. Anxiety scores of students between the units were compared using paired t-tests, and repeated-measures analysis of variance was used to measure anxiety scores within units over time. There were no significant differences in anxiety scores in the bioscience and clinical classes; however, the students were significantly more anxious in the theory classes. These findings suggest that nursing students do not find the subject of bioscience any more anxiety provoking than other nursing subjects. Bioscience educators should continue to focus on the integration of bioscience with nursing practice, while broader anxiety-reduction strategies throughout the curriculum should be implemented.

RESUMEN

Melanocortin-4 receptor (MC4R) is a G-protein-coupled receptor expressed in the brain's hypothalamus where it regulates energy homeostasis. MC4R agonists function to lower food intake and weight. In this respect, although obesity promotes hyperlipidemia and hypothalamic injury, MC4R agonists are nevertheless more effective to reduce food intake within hours of administration in overweight, rather than lean, mice. MC4R undergoes constitutive internalization and recycling to the plasma membrane with agonist binding inducing receptor retention along the intracellular route and, under prolonged exposure, desensitization. Here, we found that, in neuronal cells, lipid stress by exposure to elevated palmitate leaves unchanged the rate by which MC4R and transferrin receptor are constitutively excluded from the cell surface. However, lipid stress disrupted later steps of MC4R and transferrin receptor internalization to endosomes as well as traffic of agonist-occupied MC4R to lysosomes and MC4R desensitization. In the lipid-stressed cells, MC4R and clathrin were redistributed to the plasma membrane where they colocalized to sites that appeared by super-resolution microscopy to be modified and to have higher clathrin content than those of cells not exposed to elevated palmitate. The data suggest that lipid stress disrupts steps of endocytosis following MC4R localization to clathrin-coated sites and exclusion of the receptor from the extracellular medium. We conclude that increased effectiveness of MC4R agonists in obesity may be an unexpected outcome of neuronal injury with disrupted clathrin-dependent endocytosis and impaired receptor desensitization.

RESUMEN

Bi-allelic null mutations affecting UNC13D, STXBP2, or STX11 result in defects of lymphocyte cytotoxic degranulation and commonly cause familial hemophagocytic lymphohistiocytosis (FHL) in early life. Patients with partial loss of function are increasingly being diagnosed after presenting with alternative features of this disease, or with HLH later in life. Here, we studied two sisters with lymphocyte degranulation defects secondary to compound heterozygote missense variants in UNC13D. The older sibling presented aged 11 with linear growth arrest and delayed puberty, 2 years prior to developing transient ischemic attacks secondary to neuroinflammation and hypogammaglobulinemia, but no FHL symptoms. Her geno-identical younger sister was initially asymptomatic but then presented at the same age with severe EBV-driven infectious mononucleosis, which was treated aggressively and did not progress to HLH. The sisters had similar natural killer cell degranulation; however, while cytotoxic activity was moderately reduced in the asymptomatic patient, it was completely absent in both siblings during active disease. Following allogeneic bone marrow transplantation at the age of 15, the older child has completely recovered NK cell cytotoxicity, is asymptomatic, and has experienced an exceptional compensatory growth spurt. Her younger sister was also successfully transplanted and is currently disease free. The current study reveals previously unappreciated manifestations of FHL in patients who inherited hypomorphic gene variants and also raises the important question of whether a threshold of minimum NK function can be defined that should protect a patient from serious disease manifestations such as HLH.

RESUMEN

AIM: Haematopoietic stem cell transplantation (HSCT) is a central therapy in the treatment of primary immunodeficiency diseases (PIDs). Over the past 5 years, outcomes have been greatly improved due to earlier diagnosis, improved donor availability, advancements in graft manipulation and the use of less toxic preparative regimens. We present a 5-year audit of HSCT for PID at a single Australian tertiary hospital. METHODS: Retrospective case note review identified diagnosis, pre-transplant medical morbidity, transplant protocol, engraftment, adverse events, post-transplant immune reconstitution and general health. RESULTS: A total of 22 patients with PID underwent 24 HSCTs at our institution between 2012 and 2016. The most common indications were severe combined immunodeficiency, chronic granulomatous disease and familial haemophagocytic lymphohistiocytosis, with a genetic diagnosis in all but two patients. Reduced intensity or reduced toxicity conditioning was used in 91% of cases, and 75% of the donors were unrelated. Transplant-related mortality at day +100 was 9.5%, and cumulative overall survival was 86%. There were three mortalities, all secondary to viral infection, one of which occurred in the context of graft failure. Two patients remained on immune support, with the remainder achieving adequate immune reconstitution. CONCLUSIONS: The outcomes for HSCT for PIDs performed at Sydney Children's Hospital were in line with the world's best practice. HSCT should be considered a potential therapeutic option for all Australian PID patients with a valid disease indication.

RESUMEN

Venous malformations are slow-flow congenital vascular malformations that enlarge as the child ages and may be associated with localised intravascular coagulation, a consumptive coagulopathy characterised by elevated D-dimer and decreased fibrinogen levels. The authors review the known correlations between localised intravascular coagulation and venous malformation number, size and planes involved, and call attention to the concept of the progression of localised intravascular coagulopathy as the child ages and their venous malformations enlarge. The authors also discuss the identified therapeutic options for its investigation, management and treatment, including compression garments, anti-coagulation therapy, sclerotherapy, endovascular laser, surgical excision and sirolimus (rapamycin). Evidence for protocol improvements that may be instigated for the optimal physical and medical therapy of venous malformations complicated by localised intravascular coagulopathy is reviewed.

RESUMEN

Drawing on qualitative interviews with 22 Rwandan women, we describe the lived experiences of women survivors of gender-based violence (GBV) more than a decade and a half after the 1994 Genocide. We argue that the intersection between GBV and human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) has long-term implications: the majority of women interviewed continue to endure trauma, stigma, social isolation, and economic hardship in the postgenocide era and are in need of expanded economic and mental health support. Our findings have implications for the importance of providing integrated psychosocial support to survivors of GBV postconflict contexts.
