Recently, immunochromatography test strips (ICTS) have been fully developed for point-of-care testing (POCT). However, the intrinsic limitations including non-quantitative detection of colloidal gold ICTS and low sensitivity of fluorescence ICTS (FICTS) significantly restrict their further application in clinical diagnosis. Taking advantages of rapid colorimetric qualitative detection and fluorescence quantitation, we designed a kind of sensitive and dual-mode magnetic FICTS (mFICTS) based on PLGA@Fe3O4 super-paramagnetic nanosphere (SPMN) probes quenching multiplex fluorescer on the test line through sandwich immunoreactions...

Background: Chronic migraine (CM) affects about the 2% of the general population and it has been recognized as one of the most-disabling conditions worldwide by the World Health Organization. CM is often associated with the overuse of abortive medication, which determines the worsening of headache itself and the development of a secondary headache called medication overuse headache. The management of these associated conditions is difficult, but a growing amount of evidence is pointing out the effectiveness and the good safety profile of OnabotulinumtoxinA (OnabotA)...

INTRODUCTION: Primary care settings are often the first and only point of contact for persons with mental health and/or substance use problems. However, staff experience and training in this area are often limited. These factors as well as a multitude of other components such as structural and systemic stigma experienced by staff can lead to clients being stigmatised, leading to poorer outcomes. By developing a comprehensive intervention for primary care staff working at community health centres (CHCs) aimed at reducing stigma towards people with mental health and substance use problems (MHSUP), we sought to test an innovative and contact-based intervention consisting of staff training, raising awareness, a recovery-focused art programme and an analysis of internal policies and procedures...

BACKGROUND: HIV self-testing (HIVST) may play a role in addressing gaps in HIV testing coverage and as an entry point for HIV prevention services. We conducted a cluster randomized trial of 2 HIVST distribution mechanisms compared to the standard of care among female sex workers (FSWs) in Zambia. METHODS AND FINDINGS: Trained peer educators in Kapiri Mposhi, Chirundu, and Livingstone, Zambia, each recruited 6 FSW participants. Peer educator-FSW groups were randomized to 1 of 3 arms: (1) delivery (direct distribution of an oral HIVST from the peer educator), (2) coupon (a coupon for collection of an oral HIVST from a health clinic/pharmacy), or (3) standard-of-care HIV testing...

Objectives: Use of point-of-care testing is increasing, however many haematology analysers can only determine granulocyte count without further differentiation into neutrophils, eosinophils and basophils. Since the diagnosis of life-threatening neutropenia in cancer patients requires a distinct neutrophil count, this study aimed to determine the comparative performance between the neutrophil and granulocyte count. Design and methods: A database of 508 646 venous full blood count results measured on a laboratory reference analyser was mined from a large oncology unit...

REVIEW
Ahmad A Aref, Donald L Budenz
Timely detection of glaucomatous progression is crucial in the delivery of glaucoma care. Clinical judgment may be used to make this assessment, but relatively modest agreement among practitioners supports the use of complementary methods. Event-based analyses take into account expected localized test-retest variabilities in sensitivity, and trend-based analyses are helpful for determining and predicting overall visual function. Landmark clinical trials have used various visual field progression criteria as end points with variable performances...

Transfemoral coronary angiography may cause acute and chronic complications. The aim of the present study was to assess the effects of changing the duration of keeping sandbag over the catheter insertion site on the acute complications of coronary angiography. This quasiexperimental study was conducted on 60 patients undergoing transfemoral coronary angiography. Participants were selected using convenience sampling and were randomly assigned to intervention (n = 30) or control group (n = 30). In the intervention group, the sandbag over the insertion site of catheter was taken off at the third hour, whereas in the control group, based on the routine care, sandbag was taken off at the sixth hour after the angiography...

BACKGROUND: Perioperative aspiration leads to significant morbidity and mortality. Standard fasting periods are used to ensure an empty stomach in patients. Anesthesiologists are frequently confronted with cases of dubious adherence to these guidelines. Point-of-care gastric ultrasound is a diagnostic tool that offers information on the type and volume of gastric contents. METHODS: We performed a retrospective analysis of a departmental database containing clinical and sonographic information on elective surgical patients who had been non- compliant to the fasting guidelines...
