Application of Thyroid Imaging Reporting and Data System (TIRADS) guidelines to thyroid nodules with cytopathological correlation and impact on healthcare costs.

Aims: To assess the application of American College of Radiology Thyroid Imaging Reporting and Data System (ACR-TIRADS) guidelines and the potential reduction of unnecessary fine-needle aspirate (FNA) and cost savings through examination of cytopathological correlation.

Methods: All ultrasound-guided thyroid FNA performed between December 2017 and July 2019 at our institution were included in this study. Prior to performing each FNA, the nodules were scored according to ACR-TIRADS criteria with subsequent cytology scored according to Bethesda criteria.

Effect of Hydrocortisone on Mortality and Organ Support in Patients With Severe COVID-19: The REMAP-CAP COVID-19 Corticosteroid Domain Randomized Clinical Trial.

Importance: Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited.

Objective: To determine whether hydrocortisone improves outcome for patients with severe COVID-19.

Design, Setting, And Participants: An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin.

Bedside ultrasound in the emergency department for reduction and radial manipulation of distal radial fractures.

Objective: Distal radial fracture reduction is a common procedure in the ED. Previous studies have suggested that ultrasound (US)-guided reduction improves outcomes for patients who undergo manipulation and reduction of distal radial fractures in the ED. We aimed to investigate this with the first randomised controlled trial looking at US-guided distal radial fracture reduction.

Engineering neprilysin activity and specificity to create a novel therapeutic for Alzheimer's disease.

Neprilysin is a transmembrane zinc metallopeptidase that degrades a wide range of peptide substrates. It has received attention as a potential therapy for Alzheimer's disease due to its ability to degrade the peptide amyloid beta. However, its broad range of peptide substrates has the potential to limit its therapeutic use due to degradation of additional peptides substrates that tightly regulate many physiological processes.

The influence of age, sex, and posture on the measurement of atlantodental interval in a normal population.

Objective: The atlantodental interval (ADI) is used in assessing atlantoaxial stability. This measurement may potentially be affected by several features encountered during patient examination. This study examined the influence of 3 features: age, sex, and posture, on the measurement of ADI in a normal population.

Salt intake and reproductive function in sheep.

Producers have the possibility to combat human-induced dryland salinity by planting salt-tolerant plants such as saltbush. Saltbush has the potential to be used as a source of food for livestock at a time and place where pasture is not viable. However, saltbush contains high concentrations of sodium chloride salt and some other anti-nutritional factors that have the potential to affect feed and water intake and, directly or indirectly, the reproductive capacity of sheep.

Offspring born to ewes fed high salt during pregnancy have altered responses to oral salt loads.

Prenatal growth is sensitive to the direct and indirect effects of maternal dietary intake; manipulation can lead to behavioural and physiological changes of the offspring later in life. Here, we report on three aspects of how a high-salt diet during pregnancy (conception to parturition) may affect the offspring's response to high oral salt loads: (i) dietary preferences for salt; (ii) response to salt and water balance and aldosterone and arginine vasopressin (AVP) concentrations after an oral salt challenge; (iii) concentrations of insulin and leptin after an oral salt challenge. We used two groups of lambs born to ewes fed either a high-salt (13% NaCl) diet during pregnancy (S lambs; n = 12) or control animals born to ewes fed a conventional (0.

Reproductive capacity of Merino ewes fed a high-salt diet.

An option to increase the productivity of saline land is to graze sheep on salt-tolerant plants, which, during the summer/autumn period, can contain 20% to 25% of their dry matter as salt. This study assessed the impact of coping with high dietary salt loads on the reproductive performance of grazing ewes. From the time of artificial insemination until parturition, 2-year-old maiden Merino ewes were fed either a high-salt diet (NaCl 13% of dry matter) or control diet (NaCl 0.

Rickettsia: an unusual cause of sepsis in the emergency department.

Mediterranean spotted fever (caused by Rickettsia conorii) is one of the tick-borne rickettsioses. It is prevalent in southern Europe, Africa and central Asia and may also be seen in travellers returning from these areas. It presents with various non-specific symptoms, including fever, maculopapular rash, headache, myalgia or diarrhoea and vomiting.
