Background: Excess body weight is a risk factor for the progression of chronic kidney disease (CKD), but weight loss in CKD has been associated with higher mortality. Consequently, blanket weight loss recommendations in this population are controversial. Little data is available on the patterns of weight-change in CKD.

Traces of antibiotics reaching aquatic environment lead to the emergence of antimicrobial resistance (AMR). The efficient removal of antibiotics (ATBs) traces from wastewater is essential to tackle the AMR. In this study, a novel solid-state crosslinking method of alginate (ALG) was developed and applied to specifically remove ATBs from water.

Background: Poor solubility and dissolution rate of drugs are largely responsible for erratic drug absorption and limited oral bioavailability. Etodolac (ETO) is a non-steroidal anti-inflammatory drug (NSAID) that is classified as BCS class II (dissolution rate-dependent absorption). ETO has high safety and efficacy in pain relief and control of inflammation.

Objective: To examine and describe the effect of an oral health education program on school-based nurses' acquisition of oral health knowledge.

Methods: Three-hour synchronous videoconference sessions provided training for nurses to conduct oral health risk assessments, screen for oral diseases, deliver oral health education, apply fluoride varnish, and refer children identified in need of further assessment and treatment to a dentist. Oral health knowledge acquisition was assessed by comparing pre-training and post-training examination scores.

Background: Diabetes mellitus often exists for many years prior to diagnosis, and very little is known about the role of the prediagnosis stage of metabolic impairment in contributing to hand and upper-extremity pathology. The goal of this study is to determine the prevalence of undiagnosed glucose dysregulation in patients presenting with the 2 most commonly treated conditions of the hand and wrist.

Methods: A retrospective study was performed of hand surgery patients with no established diagnosis of prediabetes or diabetes referred for a 2-hour glucose tolerance test according to American Diabetes Association criteria.

Objectives: Derive latent profiles of accelerometry-measured moderate-vigorous physical activity (MVPA) for Hispanic/Latino adults, examine associations between latent MVPA profiles and neurocognition, and describe profiles via self-reported MVPA.

Methods: Complex survey design methods were applied to cross-sectional data from 7,672 adults ages 45-74 years in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL; 2008-2011). MVPA was measured via hip-worn accelerometers.

Background And Objectives: Chronic kidney disease progression to ESKD is associated with a marked increase in mortality and morbidity. Its progression is highly variable and difficult to predict.

Methods: This is an observational, retrospective, single-centre study.

Calciphylaxis has high mortality. Vitamin K deficiency is common in haemodialysis patients and may be a trigger for calciphylaxis due to its role in activating a tissue inhibitor of calcification, matrix Gla protein. We report a second case of a female haemodialysis patient who developed calciphylaxis twice and was successfully treated with vitamin K supplementation on both occasions.

Aim: To examine whether baseline periodontal disease is independently associated with incident prediabetes and incident diabetes in Hispanics/Latinos in the United States.

Materials And Methods: This study examined 7827 individuals, 18-74 years of age without diabetes, from the Hispanic Community Health Study/Study of Latinos. Participants received a full-mouth periodontal examination at baseline (2008-2011), and the disease was classified using the Centers for Disease Control and Prevention/American Academy of Periodontology case definitions.

Rationale & Objective: Recent studies suggest that periodontal disease may be associated with incident chronic kidney disease (CKD). However, studies have focused on older populations, and US Hispanics/Latinos were not well represented.

Study Design: Observational cohort.

The synthesis of a small number of bis(imino)anthracene derivatives is reported. They were evaluated NMR for binding efficacy to the G-quadruplex-forming oligonucleotide sequence (TTGGGTT) and show activity against the HeLa cancer cell line. These novel ligands are compared to previously synthesised G-quadruplex ligands that target telomeres and oncogenes.

Introduction: To assess the safety, efficacy, and calcium flux of an accelerated algorithm for regional citrate anticoagulation in membrane-based plasma exchange.

Methods: This was an observational study in patients receiving citrate anticoagulated, membrane-based plasma exchange at the Canberra Hospital between July 2017 and May 2020. Data were collected prospectively using an electronic medical record and compared to data from our previous published algorithm.

Ring-fused benzimidazolequinones are well-known anti-tumour agents, but dimeric ring-fused adducts are new. The alicyclic [1,2-a] ring-fused dimethoxybenzimidazole-benzimidazolequinone (DMBBQ) intermediate allows late-stage functionalization of bis-p-benzimidazolequinones. DMBBQs are chlorinated and brominated at the p-dimethoxybenzene site using nontoxic sodium halide and Oxone in HFIP/water.

Squamous cell carcinoma is the most common tumor of the hand. This malignancy requires unique treatment considerations; the surgeon and patient must balance retention of maximal functional capacity of the hand and minimization of the risk of recurrence and metastasis. Digital-sparing and digital-sacrificing therapies should be considered.

Objective: To examine the association of social support with dental caries experience in Hispanics/Latinos living in the United States (US) and to assess whether the relationship is modified by nativity status.

Methods: This cross-sectional study analysed data for 4459 dentate men and women aged 18-74 years in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study. At baseline (2008-2011), dentists quantified dental caries experience as the number of decayed, missing, and filled permanent tooth surfaces (DMFS) for all teeth excluding third molars.

Aims: To examine the association of social capital with periodontal disease severity.

Materials And Methods: We analysed data obtained from 3,994 men and women aged 18-74 years in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study (HCHS/SOL SCAS). From 2008 to 2011, dentists assessed periodontitis status with a full-mouth periodontal examination.

Drugs excreted by the kidney require dose reduction in chronic kidney disease. This adjustment depends on the severity of the disease and what proportion of the drug is eliminated by the kidneys The estimated glomerular filtration rate can generally be used to guide dose adjustment in patients with stable kidney function. However, the formula can be misleading in some patient subsets and other approaches are required At extremes of body mass, the estimated glomerular filtration rate can under- or overestimate kidney function.

Background: The American Heart Association's 2020 Impact Goals propose to improve cardiovascular health (CVH) and reduce deaths from cardiovascular diseases and stroke in the US. Targeted health promotion efforts in workplaces and communities are needed to achieve these population-level changes. The present study examined the sex-specific cross-sectional associations between employment status and ideal CVH among Hispanics/Latinos, and whether these associations were modified by age (i.
