Why do most people on dialysis not accept psychological care to increase perceptions of control in life?

Objectives: People with chronic kidney failure (CKF) on dialysis who perceive little control in life are at risk for a reduced well-being. We developed and tested an intervention aiming to enhance their perceptions of control. To gain insight into patients' care needs and acceptance of the intervention, we examined the prevalence of patients perceiving low control, their characteristics, and their reasons for (not) accepting the intervention.

SARS-CoV-2 seropositivity amongst healthcare workers in South Africa during the Omicron wave: natural infection versus vaccination.

Aims: Concerns over population-level immunity have been heightened with each successive wave of COVID-19, prompting questions about whether it is primarily derived from vaccination efforts or from previous natural infections with the virus. We wished to determine the seroprevalence of SARS-CoV-2 antibodies among healthcare workers (HCWs) in Pretoria (Tshwane), South Africa, and to establish whether they were derived from vaccination or natural infection.

Methods: Serum samples were collected from HCWs during the fourth wave of COVID-19 between 1 December 2021 and 13 March 2022.

Unveiling the P-solubilizing potential of bacteria enriched from natural colonies of Red Sea Trichodesmium spp.

Phosphorus (P) is pivotal for all organisms, yet its availability is, particularly in the marine habitat, limited. Natural, puff-shaped colonies of Trichodesmium, a genus of diazotrophic cyanobacteria abundant in the Red Sea, have been demonstrated to capture and centre dust particles. While this particle mining strategy is considered to help evade nutrient limitation, details behind the mechanism remain elusive.

Association Between Chewing Capacity and Mortality Risk: The Role of Diet and Ageing.

Aim: Masticatory dysfunction due to tooth loss is a potentially modifiable risk for mortality, but the pathway behind that remains to be investigated. This prospective study aimed to examine the role of diet and ageing in the associations between chewing capacity and long-term mortality.

Methods: Data were obtained from participants (aged ≥ 20) in the National Health Nutritional and Health Survey (NHANES 1999-2010, n = 22,900).

Electrocortical activity during resistance exercises in healthy young adults-a systematic review.

Introduction: Resistance training (RT) is known to induce both peripheral and central adaptations, resulting in enhanced strength, sports performance, and health benefits. These adaptations are specific to the training stimuli. The acute cortical mechanisms of single sessions resistance exercise (RE) are not yet understood.

Recurrent association between colonies and calcifying amoebae.

Colonies of the N-fixing cyanobacterium spp. constitute a consortium with multiple microorganisms that collectively exert ecosystem-level influence on marine carbon and nitrogen cycling, shunting newly fixed nitrogen to low nitrogen systems, and exporting both carbon and nitrogen to the deep sea. Here we identify a seasonally recurrent association between puff colonies and amoebae through a two-year survey involving over 10 000 colonies in the Red Sea.

Frustrated Radical Pairs: From Fleeting Intermediates to Isolable Species.

We present the design and comprehensive investigation of stable para-substituted triarylamine-2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) radical ion pairs (RIPs) generated via single-electron transfer (SET). We quantified the degree of SET in both solution and solid phases, utilising a suite of spectroscopic techniques including IR, EPR, NMR, and single-crystal X-ray diffraction (SC-XRD). Our findings reveal that the extent of SET is significantly influenced by the nature of the substituents (MeO > Bu > Br) and the polarity of the solvent (MeCN > DCM > toluene).

ERICH4 is not involved in the assembly and secretion of intestinal lipoproteins.

Background And Aims: The small intestine plays a central role in lipid metabolism, most notably the uptake of dietary fats that are packaged into chylomicrons and secreted into the circulation for utilisation by peripheral tissues. While microsomal triglyceride transfer protein (MTP) is known to play a key role in this pathway, the intracellular assembly, trafficking, and secretion of chylomicrons is incompletely understood.

Methods And Results: Using human transcriptome datasets to find genes co-regulated with MTTP, we identified ERICH4 as a top hit.

Antarctic krill sequester similar amounts of carbon to key coastal blue carbon habitats.

The carbon sequestration potential of open-ocean pelagic ecosystems is vastly under-reported compared to coastal vegetation 'blue carbon' systems. Here we show that just a single pelagic harvested species, Antarctic krill, sequesters a similar amount of carbon through its sinking faecal pellets as marshes, mangroves and seagrass. Due to their massive population biomass, fast-sinking faecal pellets and the modest depths that pellets need to reach to achieve sequestration (mean is 381 m), Antarctic krill faecal pellets sequester 20 MtC per productive season (spring to early Autumn).

Necessity and influencing factors for integrating oral health in cancer care for older people: a narrative review.

Purpose: The number of older people with poor oral health diagnosed with cancer is increasing rapidly. However, integration of oral health in cancer care for older people to prevent or minimize oral health complications of cancer treatments is uncommon, except in head and neck oncology. The aim of this review is to describe the need, role of, and factors influencing the integration of oral health(care) into the treatment of older people with cancer.

Impact of increased fishing on long-term sequestration of carbon by cephalopods.

Fish and other metazoans play a major role in long-term sequestration of carbon in the oceans through the biological carbon pump. Recent studies estimate that fish can release about 1,200 to 1,500 million metric tons of carbon per year (MtC year) in the oceans through feces production, respiration, and deadfalls, with mesopelagic fish playing a major role. This carbon remains sequestered (stored) in the ocean for a period that largely depends on the depth at which it is released.

Performance and microbial community composition of full-scale high-rate cascade sludge digestion system via pie-shaped reactor configuration.

A full-scale high-rate cascade anaerobic digestion (CAD) system was evaluated for its ability to enhance enzymatic sludge hydrolysis. The system included a newly built digester, innovatively divided into three pie-shaped compartments (500 m each), followed by an existing, larger digester (1500 m). The system treated a mixture of waste activated sludge and primary sludge, achieving a stable total chemical oxygen demand reduction efficiency (56.

Periodontitis: A Plausible Modifiable Risk Factor for Neurodegenerative Diseases? A Comprehensive Review.

The aim of this comprehensive review is to summarize recent literature on associations between periodontitis and neurodegenerative diseases, explore the bidirectionality and provide insights into the plausible pathogenesis. For this purpose, systematic reviews and meta-analyses from PubMed, Medline and EMBASE were considered. Out of 33 retrieved papers, 6 articles complying with the inclusion criteria were selected and discussed.

Noble Gas Analyses to Distinguish Between Surface and Subsurface Brine Releases at a Legacy Oil Site.

Attributing the sources of legacy contamination, including brines, is important to determine remediation options and to allocate responsibility. To make sound remediation decisions, it is necessary to distinguish subsurface sources, such as leaking oil and gas ("O&G") wells or natural upward fluid migrations, from surface releases. While chemical signatures of surface and subsurface releases may be similar, they are expected to imprint specific dissolved noble gas signatures, caused by the accumulation of terrigenic noble gases in subsurface leaks or re-equilibration of noble gases following surface releases.

In situ incubation of iron(II)-bearing minerals and Fe(0) reveals insights into metabolic flexibility of chemolithotrophic bacteria in a nitrate polluted karst aquifer.

Groundwater nitrate pollution is a major reason for deteriorating water quality and threatens human and animal health. Yet, mitigating groundwater contamination naturally is often complicated since most aquifers are limited in bioavailable carbon. Since metabolically flexible microbes might have advantages for survival, this study presents a detailed description and first results on our modification of the BacTrap© method, aiming to determine the prevailing microbial community's potential to utilize chemolithotrophic pathways.

The predictive value of masticatory function for adverse health outcomes in older adults: a systematic review.

Masticatory function is associated with a variety of health outcomes. The aim of this systematic review is to clarify the predictive value of masticatory function for adverse health outcomes, such as frailty, sarcopenia and malnutrition, in older adults. An online literature search covered articles published in English or Dutch in three databases (PubMed, Embase and CINAHL, last searched November 4th 2022).

Oral health assessment in institutionalized elderly: a scoping review.

When elderly become frail and in need for complex care, they can no longer live independently at home and may be admitted to nursing homes. Various studies have shown that oral health in this population is remarkably poor, which may lead to distressing situations and impacts quality of life. A variety of definitions or descriptions for oral health is used.

Unlocking Deprescribing Potential in Nursing Homes: Insights from a Focus Group Study with Healthcare Professionals.

Background: The nursing home population is characterized by multimorbidity and disabilities, which often result in extensive prescription of medication and subsequent polypharmacy. Deprescribing, a planned and supervised process of dose reduction or total cessation of medication, is a solution to combat this.

Objective: This study aimed to identify barriers and enablers of deprescribing as experienced by nursing home physicians (NHPs) and collaborating pharmacists in the specific nursing home setting.

Oral Health as a Risk Factor for Alzheimer Disease.

In patients with Alzheimer's disease pathophysiological changes of the brain that initiate the onset of Alzheimer's disease include accumulation of amyloid-β plaques and phosphorylation of tau-tangles. A rather recently considered risk factor for the onset of Alzheimer's disease is poor oral health. The aim of this systematic review of the literature was to assess the potential association(s) of oral health as a risk factor for the onset of Alzheimer's disease.

Predictive factors for the treatment success of peri-implantitis: a protocol for a prospective cohort study.

Introduction: Peri-implantitis, a common biological complication of dental implant, has attracted considerable attention due to its increasing prevalence and limited treatment efficacy. Previous studies have reported several risk factors associated with the onset of peri-implantitis (eg, history of periodontitis, poor plaque control and smoking). However, inadequate data are available on the association between these risk factors and successful outcome after peri-implantitis therapy.
