The synthesis of supramolecular polymers with controlled architecture is a grand challenge in supramolecular chemistry. Although living supramolecular polymerization via primary nucleation has been extensively studied for controlling the supramolecular polymerization of small molecules, the resulting supramolecular polymers have typically exhibited one-dimensional morphology. In this report, we present the synthesis of intriguing supramolecular polymer architectures through a secondary nucleation event, a mechanism well-established in protein aggregation and the crystallization of small molecules...

ISSUE ADDRESSED: While social determinants frameworks are still popular in research about First Nations health in Australia, a growing body of research prefers cultural determinants of health models. Cultural determinants models provide a holistic, strength-based framework to explain connections between health and contextual factors, including the potential role of music and its impact on social and emotional well-being. Given the growing international recognition of links between music, health, and wellbeing through bodies such as the World Health Organisation, this article examines whether and how music practices are acknowledged in First Nations determinants of health literature...

BACKGROUND: Optimal treatment of patients with rib fractures requires identification of those patients at risk of pulmonary complications. It is also important to determine which patients would benefit from Surgical Stabilisation of Rib Fractures (SSRF). This study aims to validate two scoring systems (RibScore and SCARF score) in predicting complications and association with SSRF in an Australian trauma population. Clinical observation suggests that complications and criteria for SSRF is associated with anatomical and physiological factors...

BACKGROUND: Coronavirus disease 2019 (COVID-19) continues to pose a global public health threat. The pandemic overstretched already weak health systems in low- and low-middle-income countries, including Ethiopia. There is a paucity of studies on the impact of COVID-19 on antenatal care access, uptake, and provision in Ethiopia. This study examines the impact of COVID-19 on antenatal care provision in the Sidama region, Ethiopia. METHODS: A concurrent mixed-methods study was conducted between 14 February and 10 May 2022 at 15 public hospitals in the Sidama region...

BACKGROUND: The traditional scarf osteotomy (TSO) has limited ability to correct the first metatarsal pronation. A novel modification that we refer to as a "dovetailed notch scarf osteotomy" (DNSO) has been developed to enhance the ability to correct coronal plane pronation. The study aimed to observe and compare TSO to DNSO in the treatment of moderate to severe hallux valgus deformity. METHODS: This retrospective study included 78 feet that had a TSO and 105 feet that had a DNSO...

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) ravaged the world, and Coronavirus Disease 2019 (COVID-19) exhibited highly prevalent oral symptoms that had significantly impacted the lives of affected patients. However, the involvement of four human coronavirus (HCoVs), namely SARS-CoV-2, SARS-CoV, MERS-CoV, and HCoV-229E, in oral cavity infections remained poorly understood. We integrated single-cell RNA sequencing (scRNA-seq) data of seven human oral tissues through consistent normalization procedure, including minor salivary gland (MSG), parotid gland (PG), tongue, gingiva, buccal, periodontium and pulp...

INTRODUCTION: Achieving the Sustainable Development Goals to reduce maternal and neonatal mortality rates will require the expansion and strengthening of quality maternal health services. Midwife-led birth centres (MLBCs) are an alternative to hospital-based care for low-risk pregnancies where the lead professional at the time of birth is a trained midwife. These have been used in many countries to improve birth outcomes. METHODS: The cost analysis used primary data collection from four MLBCs in Bangladesh, Pakistan and Uganda (n=12 MLBC sites)...

BACKGROUND: Newborn bloodspot screening is a well-established population health initiative that detects serious, childhood-onset, treatable conditions to improve health outcomes. With genomic technologies advancing rapidly, many countries are actively discussing the introduction of genomic assays into newborn screening programs. While adding genomic testing to Australia's newborn screening program could improve outcomes for infants and families, it must be considered against potential harms, ethical, legal, equity and social implications, and economic and health system impacts...

BACKGROUND: Mistreatment of women in maternity care violates human rights, erodes trust and disrupts the continuity of maternal healthcare services. Investigating Health Care Providers' (HCPs) perspectives is indispensable in uncovering drivers and designing targeted interventions. AIM: To identify the roles of HCPs' perceptions of the working environment and levels of empathy on the mistreatment of women during maternity care. METHODS: We conducted a self-administered survey among 148 maternal HCPs practising in ten health centres and four hospitals in the East Wollega Zone, Western Ethiopia, from June to September 2022...

Accidental Foreign body aspiration, especially sharp metallic objects may lead to life threatening complications. A metallic object is identified readily on a Xray chest or CT chest and helps us in ascertaining its location. A straight pin with blunt head in the shape of pearl is used in wearing a head scarf also known as hijab to hold it in place. The head scarf pin (hijab pin) if accidentally aspirated into the airway may lead to grave complications. Hence timely intervention with suitable instrumentation is essential to prevent any lethal complications...

INTRODUCTION: Demographic and health factors are known to predict vaping. Less is known about psychological predictors of vaping uptake, particularly among non-smoking adults using longitudinal designs. We aimed to model how psychological factors related to personality and mental health predicted the likelihood of vaping uptake over time in non-smoking adults ages 18+ using longitudinal data. METHODS: Longitudinal regression models utilised data from the 2018-2020 waves of the New Zealand Attitudes and Values Study to assess how the Big Five personality traits, mental distress and self-control predicted who began vaping over time among non-users (non-vapers and non-smokers), controlling for gender, age, ethnicity and economic deprivation...

Single-shot real-time femtophotography is indispensable for imaging ultrafast dynamics during their times of occurrence. Despite their advantages over conventional multi-shot approaches, existing techniques confront restricted imaging speed or degraded data quality by the deployed optoelectronic devices and face challenges in the application scope and acquisition accuracy. They are also hindered by the limitations in the acquirable information imposed by the sensing models. Here, we overcome these challenges by developing swept coded aperture real-time femtophotography (SCARF)...

BACKGROUND: Mistreatment of childbearing women continues despite global attention to respectful care. In Ethiopia, although there have been reports of mistreatment of women during maternity care, the influence of this mistreatment on the continuum of maternity care remains unclear. In this paper, we report the prevalence of mistreatment of women from various dimensions, factors related to mistreatment and also its association to the continuum of maternity care in health facilities. METHODS: We conducted an institution-based cross-sectional survey among women who gave birth within three months before the data collection period in Western Ethiopia...

BACKGROUND: High-altitude exposure changes the electrical conduction of the heart. However, reports on electrocardiogram (ECG) characteristics and potent prophylactic agents during high-altitude acclimatization and de-acclimatization are inadequate. This study aimed to investigate the effects of ubiquinol on electrophysiology after high-altitude hypoxia and reoxygenation. METHODS: The study was a prospective, randomized, double-blind, placebo-controlled trial. Forty-one participants were randomly divided into two groups receiving ubiquinol 200 mg daily or placebo orally 14 days before flying to high altitude (3900 m) until the end of the study...

Implementation of municipal solid waste (MSW) source segregation leads to a more convenient recycle of combustible MSW components. Textiles, plastics and papers are commonly available combustible components in MSW. Their shredding is conducive to resources recovery. But these components usually have high tensile strengths and are difficult to shred. To understand their mechanical strength changes in their early pyrolysis stage will help to address this problem. In this study, a universal electronic testing machine was used to determine the breaking strengths of the materials including cotton towel, polyethylene glycol terephthalate (PET), ivory board (IB), kraft paper (KP) and wool scarf in the temperature range of 30-250°C under N2 atmosphere, and the mechanisms of their strength changes were explored...

AIM: To develop a short version of the original Hammersmith Infant Neurological Examination (HINE) to be used as a screening tool (Brief-HINE) and to establish if the short examination maintains good accuracy and predictive power for detecting infants with cerebral palsy (CP). METHOD: Eleven items were selected from the original HINE ('visual response'; 'trunk posture'; 'movement quantity'; 'movement quality'; 'scarf sign'; 'hip adductor angles'; 'popliteal angle'; 'pull to sit'; 'lateral tilting'; 'forward parachute reaction'; 'tendon reflexes') identifying those items previously found to be more predictive of CP in both low- and high-risk infants...

BACKGROUND: The minimally invasive chevron Akin osteotomy technique is indicated for the treatment of symptomatic mild to moderate hallux valgus deformities. The aim of the procedure is to restore alignment of the first ray while minimizing soft-tissue disruption. DESCRIPTION: Prior to the procedure, radiographs are utilized to characterize the patient's hallux valgus deformity by determining the hallux valgus angle and intermetatarsal angle. The metatarsal rotation is also assessed via the lateral round sign and sesamoid view...

BACKGROUND: The purpose of this systematic review and meta-analysis was to compare the clinical and radiographic outcomes between patients undergoing scarf osteotomy and scarf-Akin osteotomy for the management of hallux valgus deformity. METHODS: A systematic review of the MEDLINE, EMBASE and Cochrane Library databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies reporting clinical data following scarf osteotomy and scarf-Akin osteotomy for the treatment of hallux valgus were included and assessed...

BACKGROUND: Traditional Scarf osteotomy (TSO) is an effective procedure with a good record in moderate to severe hallux valgus (MSHV) surgery. In order to overcome shortcomings of TSO, Modified Rotary Scarf osteotomy (MRSO) was introduced in this study, which aimed to compare the clinical and radiological outcome in the patients treated with MRSO or TSO. METHODS: Of 175 patients (247 feet) with MSHV, 100 patients (138 feet) treated with MRSO and 75 patients (109 feet) treated with TSO were evaluated according to relevant indicators in twenty-four months follow-up...

The administration of radiolabeled drug candidates is considered the gold standard in absorption, distribution, metabolism and excretion (ADME) studies for small molecule drugs, since it allows facile and accurate quantification of parent drug, metabolites and total drug related material independent of the compound structure. The choice of the position of the radiolabel, typically 14 C or 3 H, is critical to obtain relevant information. Sometimes a biotransformation reaction may lead to cleavage of a part of the molecule...
