RESUMEN

INTRODUCTION: Students can expect to experience stressors associated with their studies that can have detrimental effects on their mental well-being if not properly managed. Drawing on a positive psychology paradigm, protective factors can help students to counter study-related stressors and contribute to their mental well-being and academic success. The relationship between protective factors, such as maintaining perspective and building networks, with stress severity and positive mental well-being was examined in a sample of Australian university students undertaking postgraduate coursework. METHODS: Students completed a survey measuring stress from the Depression, Anxiety and Stress Scale (DASS), positive mental well-being from the Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS), and seven protective factors from the Resilience at University (RAU) scale. Bivariate correlations were calculated for the RAU protective factors with stress and mental well-being. ANOVA examined the RAU protective factors in relation to mental well-being and stress severity groupings. RESULTS: All seven protective factors had a positive and significant relationship with positive mental well-being, and six of the seven protective factors had a negative and significant relationship with stress. A statistically significant difference was found for six of the seven RAU protective factors according to mental well-being group, and three of the seven RAU protective factors group according to stress severity group. A linear effect emerged between level of protective factor and mental well-being group, with participants in the high well-being group having the highest level of protective factors. CONCLUSION: Universities should focus on the development of protective factors to support students' well-being and help them to flourish in their studies.

RESUMEN

Situated in critiques of the "moral muteness" of technical rationality, we examine concepts of ethics and the avoidance of ethical language among Australian gas pipeline engineers. We identify the domains in which they saw ethics as operating, including public safety, environmental protection, sustainability, commercial probity, and modern slavery. Particularly with respect to ethical matters that bear on public safety, in the course of design and operational activities, engineers principally advocated for action using technical language, avoiding reference to potential consequences such as death or destruction of property. Within their organizations, they saw themselves as occupying a technical "line of defense". We argue that this focus on technical language is action-oriented. Ethics tells practitioners of unacceptable outcomes, but it does not guide them in what they need to do to avoid that outcome in practice. We observed some cases where engineers had not made the connection between their role and ethics in the sense of public safety. We argue that muteness on ethical matters can obscure the nature of the risk where technical advice is being taken on by non-technical actors, and where technical actors themselves do not have a clear sense of their public safety obligations.

RESUMEN

OBJECTIVE: Nosebleed, also known as epistaxis, is a common problem that occurs at some point in at least 60% of people in the United States. While the majority of nosebleeds are limited in severity and duration, about 6% of people who experience nosebleeds will seek medical attention. For the purposes of this guideline, we define the target patient with a nosebleed as a patient with bleeding from the nostril, nasal cavity, or nasopharynx that is sufficient to warrant medical advice or care. This includes bleeding that is severe, persistent, and/or recurrent, as well as bleeding that impacts a patient's quality of life. Interventions for nosebleeds range from self-treatment and home remedies to more intensive procedural interventions in medical offices, emergency departments, hospitals, and operating rooms. Epistaxis has been estimated to account for 0.5% of all emergency department visits and up to one-third of all otolaryngology-related emergency department encounters. Inpatient hospitalization for aggressive treatment of severe nosebleeds has been reported in 0.2% of patients with nosebleeds. PURPOSE: The primary purpose of this multidisciplinary guideline is to identify quality improvement opportunities in the management of nosebleeds and to create clear and actionable recommendations to implement these opportunities in clinical practice. Specific goals of this guideline are to promote best practices, reduce unjustified variations in care of patients with nosebleeds, improve health outcomes, and minimize the potential harms of nosebleeds or interventions to treat nosebleeds. The target patient for the guideline is any individual aged ≥3 years with a nosebleed or history of nosebleed who needs medical treatment or seeks medical advice. The target audience of this guideline is clinicians who evaluate and treat patients with nosebleed. This includes primary care providers such as family medicine physicians, internists, pediatricians, physician assistants, and nurse practitioners. It also includes specialists such as emergency medicine providers, otolaryngologists, interventional radiologists/neuroradiologists and neurointerventionalists, hematologists, and cardiologists. The setting for this guideline includes any site of evaluation and treatment for a patient with nosebleed, including ambulatory medical sites, the emergency department, the inpatient hospital, and even remote outpatient encounters with phone calls and telemedicine. Outcomes to be considered for patients with nosebleed include control of acute bleeding, prevention of recurrent episodes of nasal bleeding, complications of treatment modalities, and accuracy of diagnostic measures. This guideline addresses the diagnosis, treatment, and prevention of nosebleed. It focuses on nosebleeds that commonly present to clinicians via phone calls, office visits, and emergency room encounters. This guideline discusses first-line treatments such as nasal compression, application of vasoconstrictors, nasal packing, and nasal cautery. It also addresses more complex epistaxis management, which includes the use of endoscopic arterial ligation and interventional radiology procedures. Management options for 2 special groups of patients-patients with hereditary hemorrhagic telangiectasia syndrome and patients taking medications that inhibit coagulation and/or platelet function-are included in this guideline. This guideline is intended to focus on evidence-based quality improvement opportunities judged most important by the guideline development group. It is not intended to be a comprehensive, general guide for managing patients with nosebleed. In this context, the purpose is to define useful actions for clinicians, generalists, and specialists from a variety of disciplines to improve quality of care. Conversely, the statements in this guideline are not intended to limit or restrict care provided by clinicians based on their experience and assessment of individual patients. ACTION STATEMENTS: The guideline development group made recommendations for the following key action statements: (1) At the time of initial contact, the clinician should distinguish the nosebleed patient who requires prompt management from the patient who does not. (2) The clinician should treat active bleeding for patients in need of prompt management with firm sustained compression to the lower third of the nose, with or without the assistance of the patient or caregiver, for 5 minutes or longer. (3a) For patients in whom bleeding precludes identification of a bleeding site despite nasal compression, the clinician should treat ongoing active bleeding with nasal packing. (3b) The clinician should use resorbable packing for patients with a suspected bleeding disorder or for patients who are using anticoagulation or antiplatelet medications. (4) The clinician should educate the patient who undergoes nasal packing about the type of packing placed, timing of and plan for removal of packing (if not resorbable), postprocedure care, and any signs or symptoms that would warrant prompt reassessment. (5) The clinician should document factors that increase the frequency or severity of bleeding for any patient with a nosebleed, including personal or family history of bleeding disorders, use of anticoagulant or antiplatelet medications, or intranasal drug use. (6) The clinician should perform anterior rhinoscopy to identify a source of bleeding after removal of any blood clot (if present) for patients with nosebleeds. (7a) The clinician should perform, or should refer to a clinician who can perform, nasal endoscopy to identify the site of bleeding and guide further management in patients with recurrent nasal bleeding, despite prior treatment with packing or cautery, or with recurrent unilateral nasal bleeding. (8) The clinician should treat patients with an identified site of bleeding with an appropriate intervention, which may include one or more of the following: topical vasoconstrictors, nasal cautery, and moisturizing or lubricating agents. (9) When nasal cautery is chosen for treatment, the clinician should anesthetize the bleeding site and restrict application of cautery only to the active or suspected site(s) of bleeding. (10) The clinician should evaluate, or refer to a clinician who can evaluate, candidacy for surgical arterial ligation or endovascular embolization for patients with persistent or recurrent bleeding not controlled by packing or nasal cauterization. (11) In the absence of life-threatening bleeding, the clinician should initiate first-line treatments prior to transfusion, reversal of anticoagulation, or withdrawal of anticoagulation/antiplatelet medications for patients using these medications. (12) The clinician should assess, or refer to a specialist who can assess, the presence of nasal telangiectasias and/or oral mucosal telangiectasias in patients who have a history of recurrent bilateral nosebleeds or a family history of recurrent nosebleeds to diagnose hereditary hemorrhagic telangiectasia syndrome. (13) The clinician should educate patients with nosebleeds and their caregivers about preventive measures for nosebleeds, home treatment for nosebleeds, and indications to seek additional medical care. (14) The clinician or designee should document the outcome of intervention within 30 days or document transition of care in patients who had a nosebleed treated with nonresorbable packing, surgery, or arterial ligation/embolization. The policy level for the following recommendation, about examination of the nasal cavity and nasopharynx using nasal endoscopy, was an option: (7b) The clinician may perform, or may refer to a clinician who can perform, nasal endoscopy to examine the nasal cavity and nasopharynx in patients with epistaxis that is difficult to control or when there is concern for unrecognized pathology contributing to epistaxis.

RESUMEN

This plain language summary explains nosebleeds, also known as epistaxis (pronounced ep-ih-stak-sis), to patients. The summary applies to any individual aged 3 years and older with a nosebleed or history of nosebleed who needs medical treatment or wants medical advice. It is based on the 2020 "Clinical Practice Guideline: Nosebleed (Epistaxis)." This guideline uses research to advise doctors and other health care providers on the diagnosis, treatment, and prevention of nosebleeds. The guideline includes recommendations that are explained in this summary. Recommendations may not apply to every patient but can be used to help patients ask questions and make decisions in their own care.

RESUMEN

Proinflammatory prostaglandins and cytokines are involved in the initiation of human labor and delivery. Although cyclopentenone prostaglandins regulate the formation of these prolabor mediators via nuclear factor-kappaB (NF-kappaB) and/or peroxisome proliferator-activated receptor-gamma, recent evidence suggests that they do not exist in vivo. Cyclopentenone isoprostanes (IsoPs), which are highly reactive structural isomers of bioactive cyclopentenone prostaglandins, do exist physiologically and have been shown to inhibit the inflammatory response in macrophages. Therefore the aim of this study was to determine the effect of the synthetic cyclopentenone IosP 15-A(2)-IsoP on the expression of prolabor mediators in human gestational tissues. Human placenta and gestational membranes (n=5) were incubated in the absence or presence of 12.5, 25, and 50 microM 15-A(2)-IsoP with 10 microg/ml lipopolysaccharide (LPS). Treatment of placenta and fetal membranes with 15-A(2)-IsoP caused a dose-dependent decrease in LPS-stimulated release of the cytokines IL-1beta, IL-6, IL-8, and TNF-alpha and the prostaglandins PGE(2) and PGF(2)alpha. NF-kappaB p65 DNA binding activity was significantly inhibited by treatment with 50 microM 15-A(2)-IsoP. Collectively, these data suggest that 15-A(2)-IsoP exhibits antiinflammatory properties via antagonism of NF-kappaB activity. Cyclopentenone IsoPs may serve as negative feedback regulators of the inflammatory response in human gestational tissues.

RESUMEN

AIM: Cervico-vaginal fluid (CVF) may provide insight into the biochemical pathways of human reproduction and parturition. The aim of this study was to establish a 2-D electrophoretic map of human CVF in healthy, pregnant women at term. METHODS: CVF was collected, concentrated and processed by routine 2-D polyacrylamide gel electrophoresis using pH 4-7-immobilised pH gradient strips and 8-16% gradient polyacrylamide gels. Imaged gels were analysed, yielding more than 400 proteins. A total of 157 proteins were common to all gels with a subgroup of the most abundant proteins being excised and characterised either by MALDI or by electrospray ion-trap mass spectrometry. RESULTS: Twenty-one proteins were successfully identified, yielding 15 different proteins. These included blood transport proteins (albumin and transthyretin); a structural protein (beta-actin); proteins involved in fatty acid metabolism (fatty acid-binding protein and acetyl-CoA-binding protein); a calcium-binding protein (annexin III); an anti-inflammatory cytokine (interleukin-1 receptor antagonist); proteinase inhibitors (alpha-1-antitrypsin, monocyte/neutrophil elastase inhibitor, squamous cell carcinoma antigen-1 and cystatin A); and enzymes involved in oxidative stress defence (thioredoxin, peroxiredoxin 2, glutathione S-transferase P and copper,zinc superoxide dismutase). CONCLUSION: CVF is a complex body fluid consisting of both endogenous and environmental proteins. The putative role of some of these proteins in the human reproductive tract is discussed.
