High-sensitivity detection of minute quantities or concentration variations of analytes of clinical importance is critical for biosensing to ensure accurate disease diagnostics and reliable health monitoring. A variety of sensitivity-improving concepts have been proposed from chemical, physical, and biological perspectives. In this review, elements that are responsible for sensitivity enhancement are classified and discussed in accordance with their operating steps in a typical biosensing workflow that runs through sampling, analyte recognition, and signal transduction. With a focus on optical biosensing, exemplary sensitivity-improving strategies are introduced, which can be developed into "plug-and-play" modules for many current and future sensors, and discuss their mechanisms to enhance biosensing performance. Three major strategies are covered i) amplification of signal transduction by polymerization and nanocatalysts, ii) diffusion-limit-breaking systems for enhancing sensor-analyte contact and subsequent analyte recognition by fluid-mixing and analyte-concentrating, and iii) combined approaches that utilize renal concentration at the sampling and recognition steps and chemical signal amplification at the signal transduction step.In 2019 Health Education England supported health care library knowledge service staff in the Northern region to organise a two-day event to share knowledge and expertise, and to develop their networks. The article describes how the event was organised, emphasising the advance planning and development opportunities provided for participants, such as webinars, and randomised coffee trial meetings between participants. Of the 100 participants, 60 delivered a poster, workshop or presentation. Reflective evaluation of the event by the organising committee indicated that networking was actively encouraged, and that a higher proportion of library assistants participated than usual. Concludes that the virtual aspects of the event worked well, and that future events could include a mix of face to face and virtual sessions. D.I.Does sports science librarianship differ from other aspects of health librarianship? Or are sports science librarians more likely to identify as generalist librarians? This editorial introduces the salutogenic approach to sport, factors that support human health and well-being, and highlights the challenge of resourcing the diversity of subjects covered by sports sciences. Highlighting key parallels with medicine and public health, it concludes by advocating for closer alignment between sports and health science librarianship.
Autoimmune processes are now an increasingly recognized cause of acute and chronic pancreatitis. Autoimmune pancreatitis is a rare, benign pathology with two distinct clinicopathologic subtypes. The aim of this study was to compare the presentation, diagnostic considerations and outcomes of patients with biopsy-proven type 1 and 2 autoimmune pancreatitis (AIP).
A retrospective review of the Queensland Health pathology database of histologically proven AIP was conducted. Parameters compared included demographics, diagnostic criterion and post-treatment outcomes.
Twenty-three patients had a confirmed histological diagnosis of AIP (type 1 = 13, type 2 = 10). Patients with type 2 AIP were younger (median age 49 versus 59 years, P < 0.05). There was no significant difference in gender distribution of disease at presentation. Type 2 AIP presented with significant increased focal pancreatic changes on cross-sectional imaging (80% versus 54%, P < 0.05). Serum IgG4 levels were raised (>1.40 g/L) in 69% of patients with type 1 AIP and not detected in type 2 (P < 0.01). Concurrent underlying inflammatory bowel disease was present in a higher proportion of type 2 AIP (40% versus 15%, P < 0.05). A significantly increased proportion of patients with type 2 AIP underwent surgical resection (70% versus 30%, P < 0.05). Conservative management was utilized in more patients with type 1 disease (54% versus 30%). On follow-up, two patients have experienced symptomatic relapse at 6-18 months.
Diagnostic challenges do exist and clinicians must suspect 2 type AIP in young, serum IgG4-negative inflammatory bowel disease patients with recurrent pancreatitis.

Day-only laparoscopic cholecystectomy (DOLC) has been shown to be safe and feasible yet has not been widely implemented in Australia. This study explores the introduction of routine DOLC to Westmead Hospital, and highlights the barriers to its implementation.
Routine day-only cholecystectomy protocol was introduced at Westmead Hospital in 2014. A retrospective review of patients who underwent elective laparoscopic cholecystectomy during a 12-month period in 2014 was compared to a 12-month period in 2018, to examine the changes in practice after implementation of a unit protocol. Data were collected on patient demographics, admission category, outcomes and re-presentations.
A total of 282 patients were included in the study, of these 169 were booked as day procedures, with 124 (73%) successfully discharged on the same day. There was a significant increase in the proportion of patients booked as day-only from 2014 to 2018 (48% versus 73%, P < 0.001). Day-only failure rates (unplanned overnight admissioed outpatient review can be minimized by optimizing both intra- and post-operative pain management. Individual surgeon and anaesthetist preferences remain an obstacle to a standardized protocol in the Australian setting.The article describes Mieczysław Albert Krąpiec's perspective on four classic philosophical images of man and the resulting theoretical and practical implications for the nursing profession. selleck products The first three images, namely man as a set of elements, man as a soul imprisoned in the body and man as a rational animal, are regarded by Krąpiec as reductionist anthropologies and are thus inadequate for nursing. The first image reduces man to a biological element. The second one reduces man to a soul and treats a body as something an obstacle in personal development. The third image absolutizes reason in man. While the body is not rejected in this image, it is viewed as an indifferent mass. The last image, which regards man as a person, is an adequate image for nursing. The exceptional character of man emphasized in this image is determined by the following personal qualities the ability for cognition, freedom, love, religiousness, dignity, subjectivity to law and completeness. These characteristics reveal the specificity of personal being in both the body and the spirit.
