Introduction: Telepractice has the potential to align with the directive to reduce inequalities by United Nations Sustainable Development Goal 10. Telepractice additionally addresses a national digital health strategic plan for accessible digitally enabled models of care. To plan improvements, it is essential to understand the experience of telepractice for people with disability, which may be achieved through an approach such as journey mapping.

Article Synopsis
  • The study aimed to analyze how quickly Cutibacterium bacteria repopulate the skin after using chlorhexidine and isopropyl alcohol for surgical preparation.
  • Skin swabs taken from ten shoulders of five male subjects showed that while the bacterial load decreased initially after treatment, it began to increase significantly within 30 minutes and returned to baseline levels by 240 minutes.
  • The findings suggest that even after skin preparation, the sebaceous glands beneath the skin may act as reservoirs for bacteria, potentially increasing the risk of contamination during shoulder surgery.

The dataset derives from a thorough laboratory characterization of all existing stabilization technologies suitable for coarse-graded aggregates. They include two traditional binders (based on cement and bitumen) and eleven nontraditional binders (based on brine salt, clay, organic non-petroleum, organic petroleum and synthetic polymer). The dataset derives from four laboratory test operations: repeated load triaxial test performed both before and after exposing the investigated samples to ten freeze-thaw cycles, weight measurement of Marshall specimens during ten freeze-thaw cycles and a modified version of rolling bottle test.

Human immunodeficiency virus (HIV) viral load (VL) is an important quantitative marker of disease progression and treatment response in people living with HIV infection, including children with perinatally acquired HIV. Measures of VL are often used to predict different outcomes of interest in this population, such as HIV-associated neurocognitive disorder. One popular approach to summarizing historical viral burden is the area under a time-VL curve (AUC).

Introduction: The importance of shared decision making (SDM) for informed consent has been emphasised in the updated regulatory guidelines. Errors of completion, legibility and omission have been associated with paper-based consent forms. We introduced a digital consent process and compared it against a paper-based process for quality and patient reported involvement in shared decision making.

Article Synopsis
  • Antiretroviral therapy (ARV) in HIV-infected children can lead to mitochondrial toxicity, myopathy, and lactic acidosis, prompting a study on metabolic and genetic factors linked to dysfunctional fatty acid oxidation (FAO).
  • In the study involving 74 children on ARV treatment, researchers compared acylcarnitine profiles of those with myopathy against those without, finding a high prevalence of abnormal profiles in both groups but no significant link to myopathy.
  • Results indicated that longer NRTI and protease inhibitor usage correlated with increased odds of ACP abnormalities; additionally, specific genetic variants in the SLC22A5 gene were related to cardiomyopathy, suggesting a complex relationship between ARV exposure,

Article Synopsis
  • This study analyzed how the COVID-19 pandemic affected upper limb referrals and surgeries during the initial lockdown and the subsequent easing of restrictions in Britain.
  • During the 12-week observation, researchers noted a significant increase in upper limb referrals (158%) and operative cases (133%) once the lockdown was eased, with a notable rise in sporting injuries, particularly cycling-related injuries.
  • Results indicate that upper limb surgeries during the pandemic are safe, as no postoperative patients tested positive for COVID-19 within 14 days, highlighting the increased demand and safety of such procedures during this time.

The collected dataset derives from the laboratory testing of bentonite clay investigated as a stabilization technology for the unbound layers of road pavements. The effect of two kinds of bentonite (calcium based and sodium based) are assessed on two aggregate types commonly used as road construction materials. The investigation program, performed by means of repeated load triaxial tests, encompasses the different combinations of bentonite and aggregate types; two replicate specimens are tested dried for each condition.

Background: In persons living with HIV, mitochondrial disease (MD) is difficult to diagnose, as clinical signs are non-specific with inconsistent patterns. Fibroblast growth factor 21 (FGF21) and growth differentiation factor 15 (GDF15) are mitokines elevated in MD patients without HIV, and associated with cardiometabolic comorbidities in adults living with HIV. We assessed relationships of these biomarkers with MD in children living with perinatally-acquired HIV infection (CPHIV).

While veterinarians are instrumental to the welfare of calves (), limited knowledge exists concerning veterinary perceptions towards perioperative pain management in calves. As a part of a larger, nationwide study investigating the perceptions of veterinarians towards calf welfare, the current work sought to quantify veterinary perceptions towards perioperative pain management, including barriers to its use, and investigate demographic influences affecting those perceptions. An electronic mixed-methods survey was completed by 104 veterinarians registered with the Veterinary Council of New Zealand.

Background: Human immunodeficiency virus (HIV)-exposed, uninfected (HEU) infants experience higher rates of morbidity and mortality than HIV-unexposed, uninfected (HUU) infants. Few studies have examined whether particular infections and/or immune responses are associated with hospitalization among HEU infants born in the United States.

Methods: We evaluated a subset of HEU infants enrolled in the International Maternal Pediatric Adolescent AIDS Clinical Trials Group P1025 and/or Pediatric HIV/AIDS Cohort Study Surveillance Monitoring for ART Toxicities studies.

Despite considerable reduction of mother-to-child transmission (MTCT) of HIV through use of maternal and infant antiretroviral therapy (ART), over 150,000 infants continue to become infected with HIV annually, falling far short of the World Health Organization goal of reaching <20,000 annual pediatric HIV cases worldwide by 2020. Prior to the widespread use of ART in the setting of pregnancy, over half of infants born to HIV-infected mothers were protected against HIV acquisition. Yet, the role of maternal immune factors in this protection against vertical transmission is still unclear, hampering the development of synergistic strategies to further reduce MTCT.

Despite recent legislative amendments to address areas of highest risk to the welfare of calves () in New Zealand, there are prevailing concerns that animal welfare science knowledge has not been adopted in practice. As a part of a larger, nationwide study investigating the perceptions of veterinarians towards calf welfare, the aim of the current work was to investigate the perceptions of veterinarians towards the level of welfare protection afforded to young "bobby" calves in New Zealand. This study also explored concerns for welfare compromise and identified barriers to welfare-related change for calves more generally.
