The moderating role of psychological resilience in the relationship between fear of COVID-19 and psychological distress, in a cohort of rural and regional healthcare workers. During major lockdowns in Victoria, Australia 2020-2021.

The emergence of the COVID-19 pandemic resulted in substantial pressures for healthcare workers across the world. The association between fear of COVID-19 and psychological distress, and the role of psychological resilience have gained research interest. The current study aimed to investigate the cross-sectional association between fear of COVID-19 and psychological distress, in Australian rural/regional healthcare workers and determine whether resilience modifies this association.

Indicators to support local public health to reduce the impacts of heat on health.

Heat exposure presents a significant weather-related health risk in England and Wales, and is associated with acute impacts on mortality and adverse effects on a range of clinical conditions, as well as increased healthcare costs. Most heat-related health outcomes are preventable with health protection measures such as behavioural changes, individual cooling actions, and strategies implemented at the landscape level or related to improved urban infrastructure. We review current limitations in reporting systems and propose ten indicators to monitor changes in heat exposures, vulnerabilities, heat-health outcomes, and progress on adaptation actions.

The summer indoor temperatures of the English housing stock: Exploring the influence of dwelling and household characteristics.

As the high temperatures experienced during the summer of 2018 may become commonplace by 2050, adaptation to higher indoor temperatures while minimising the need for mechanical cooling is required. A thorough understanding of the factors that influence indoor temperatures can enable the design of healthier and safer dwellings under a warming climate. The aim of this paper is to provide further insight into the topic of indoor overheating through the analysis of the largest recent sample of English dwellings, the 2011 Energy Follow-Up Survey, comprised of 823 dwellings.

Mucins as multifunctional building blocks of biomaterials.

Mucins are large glycoproteins that are ubiquitous in the animal kingdom. Mucins coat the surfaces of many cell types and can be secreted to form mucus gels that assume important physiological roles in many animals. Our growing understanding of the structure and function of mucin molecules and their functionalities has sparked interest in investigating the use of mucins as building blocks for innovative functional biomaterials.

Genetically Engineered Mucoadhesive Spider Silk.

Mucoadhesion is defined as the adhesion of a material to the mucus gel covering the mucous membranes. The mechanisms controlling mucoadhesion include nonspecific electrostatic interactions and specific interactions between the materials and the mucins, the heavily glycosylated proteins that form the mucus gel. Mucoadhesive materials can be used to develop mucosal wound dressings and noninvasive transmucosal drug delivery systems.

Mucin-Inspired Lubrication on Hydrophobic Surfaces.

In the human body, high-molecular-weight glycoproteins called mucins play a key role in protecting epithelial surfaces against pathogenic attack, controlling the passage of molecules toward the tissue and enabling boundary lubrication with very low friction coefficients. However, neither the molecular mechanisms nor the chemical motifs of those biomacromolecules involved in these fundamental processes are fully understood. Thus, identifying the key features that render biomacromolecules such as mucins outstanding boundary lubricants could set the stage for creating versatile artificial superlubricants.

Elective hepatic resection is feasible and safe in a regional centre.

Background: Hepatic resectional surgery remains a highly specialized area of general surgery usually reserved for completion at tertiary metropolitan referral centres. Port Macquarie, on the Mid North Coast of New South Wales, is the only regionally based hospital offering surgery of this nature in mainland Australia. The purpose of this study is to review the data for patients undergoing hepatic resectional surgery in this non-metropolitan centre in order to illustrate that these operations can be carried out safely in a regional setting with comparable results to tertiary-level centres.

Validation of an oncoplastic breast simulator for assessment of technical skills in wide local excision.

Background: Simulation enables safe practice and facilitates objective assessment of technical skills. However, simulation training in breast surgery is rare and assessment remains subjective. The primary aim was to evaluate the construct validity of technical skills assessments in wide local excision (WLE).

Detailed tracking of body and leg movements of a freely walking female cricket during phonotaxis.

We describe a semi-automated tracking system for insect motion based on commercially available high-speed video cameras and freely available software. We use it to collect detailed three-dimensional kinematic information from female crickets performing free walking phonotaxis towards a calling song stimulus. We mark the insect's joints with small dots of paint and record the movements from underneath with a pair of cameras following the insect as it walks on the transparent floor of an arena.

Long-term results of Mitchell's procedure for hallux valgus deformity: a 5- to 20-year followup in 204 cases.

Background: There are limited studies on the long term outcome of Mitchell's osteotomy for hallux valgus deformity. We present the long term results of 204 cases.

Materials And Methods: Postoperative clinical and radiological evaluation with a mean follow up of 12.

A systematic review and meta-analysis of the randomized controlled trials on adjuvant intraperitoneal chemotherapy for resectable gastric cancer.

Background: The purpose of this systematic review and meta-analysis was to determine the effectiveness and safety of adjuvant intraperitoneal chemotherapy for patients with locally advanced resectable gastric cancer.

Methods: Studies eligible for this systematic review included those in which patients with gastric cancer were randomly assigned to receive surgery combined with intraperitoneal chemotherapy versus surgery without intraperitoneal chemotherapy. There were no language restrictions.

Reconstruction of the anterior cruciate ligament using the polyester ABC ligament scaffold: a minimum follow-up of four years.

We carried out a prospective study of 71 patients who had undergone reconstruction of the anterior cruciate ligament with the ABC scaffold. Their mean age was 28 years (18 to 50). All had either sub-acute or chronic traumatic deficiency of the ligament.

Medium-term results with a primary cemented rotating-hinge total knee replacement. A 7- to 15-year follow-up.

We reviewed 100 cemented Endo-model rotating-hinge (Waldemar Link GMBH & Co, Hamburg, Germany) total knee replacements in 80 patients with a mean age of 70 years (56 to 85) at a mean post-operative follow-up of 11 years (7 to 15). Good or excellent results were seen in 91% of knees and survival at 15 years was 96.1%.

Uncemented total hip replacements and thigh pain.

We reviewed 51 uncemented total hip replacements (THRs) in 44 patients (mean age 62 years) and average postoperative follow-up period of 4 years. The evaluation system used was based on that of D'Aubigne-Postel-Charnley, and the excellent and very good results totalled over 90%. There were no revisions or aseptic loosenings, and only one late infection and one death due to cardiac infarction.

Histological alterations in mice induced by Pseudomonas aeruginosa slime glycolipoprotein.

The time course of lesion development in mice induced by a single intraperitoneal (ip) LD50 dose of Pseudomonas aeruginosa slime glycolipoprotein (GLP) was studied. Slime GLP exerted a marked effect on the lungs, liver and kidneys without any microscopic changes in other organs. The first histological lesions were observed in the lungs 7h after ip injection and were characterized by thickening and pleomorphic inflammatory infiltration of the intraalveolar septae leading to focal atelectasis by 28 h.
