Altered extracellular matrix and mechanotransduction gene expression in rat bone tissue following long-term estrogen deficiency.

Osteoporosis is primarily associated with bone loss, but changes in bone tissue matrix composition and osteocyte mechanotransduction have also been identified. However, the molecular mechanisms underlying these changes and their relation to bone loss are not fully understood. The objectives of this study were to (1) conduct comprehensive temporal gene expression analyses on cortical bone tissue from ovariectomized rats, with a specific focus on genes known to govern matrix degradation, matrix production, and mechanotransduction, and (2) correlate these findings with bone mass, trabecular and cortical microarchitecture, and mineral and matrix composition.

Effectiveness of anthocyanin-containing foods and nutraceuticals in mitigating oxidative stress, inflammation, and cardiovascular health-related biomarkers: a systematic review of animal and human interventions.

Cardiovascular diseases (CVDs) are a group of chronic health disorders prevalent worldwide that claim millions of lives yearly. Inflammation and oxidative stress are intricately associated with myocardial tissue damage, endothelial dysfunction, and increased odds of heart failure. Thus, dietary strategies aimed at decreasing the odds of CVDs are paramount.

Association Between Hypoglycemia and the Occurrence of Early Onset Sepsis in Premature Infants.

Background: We examined the association between hypoglycemia and the occurrence of early onset sepsis (EOS) in premature infants admitted to the neonatal intensive care unit (NICU).

Methods: We included infants discharged from 358 NICUs between 1997 and 2020 with gestational age <34 weeks, ≥1 culture collected in the first 3 days of life, and ≥1 serum glucose value recorded on the day of or day prior to culture collection. We used multivariable logistic regression and inverse probability weighting (IPW) and constructed models for three definitions of hypoglycemia: American Academy of Pediatrics (AAP), Pediatric Endocrine Society, and a definition based on neurodevelopmental studies.

Near-Death Experiences and Sleep Disturbance: An Exploratory Study Using Wrist Actigraphy.

Near-death experiences (NDEs) are nonordinary states of consciousness typically occurring on the brink of death. Sleep changes after NDEs have been described, including shorter sleep duration, longer sleep latency, and more sleep disturbances; however, objective verification is lacking. In this exploratory research, 57 participants took part in a 14-day actigraphy study and were assigned to three groups: those who have had an NDE ( n = 26); those who experienced a near-death event but without NDE ( n = 12); and those who had never come close to death ( n = 19).

Using a teach-back intervention significantly improves knowledge, perceptions, and satisfaction of patients with Nurses' discharge medication education.

Background: Evidence indicates that patients desire medication information, but clinicians often fail to teach this information in an understandable way. Teach-Back promotes effective clinician-patient communication and enhances medication adherence, satisfaction with education, and hospital experiences.

Aims: This study examined effects of a nurse-led Teach-Back intervention, Teaching Important Medication Effects (TIME), compared with usual care on patients' knowledge, experiences, and satisfaction with medication education before and after discharge.

Patient-reported outcome measures in third molar surgery: a scoping review.

Despite a surge of interest in patient-centred outcomes (PROMs) in healthcare settings, they remain an underutilised resource in third molar surgery. Clinicians and researchers in the field of oral surgery who are interested in incorporating PROMs into their clinical practice may face challenges in instrument selection with as yet no consensus registry available. PROMs have undoubtedly transcended their original brief as research instruments, with the collection of PROMs data now a routine undertaking in many healthcare systems.

Autologous platelet concentrates in oral surgery: protocols, properties, and clinical applications.

Autologous platelet concentrates (APCs) are a relatively new phenomenon, with initial reports of their regenerative potential published as recently as 1998. Despite their relative infancy, a huge body of evidence exists in support of their capacity to promote osseous and soft tissue regeneration through the physiologic processes of platelet activation and subsequent growth factor release. APCs have transformed many areas of healthcare and are now considered an essential component of the surgical milieu.

Variations in reporting of clinician-reported outcome measures in third molar surgery: A focused review.

Clinician-reported outcome measures (ClinRO measures) play a fundamental role in quality assurance throughout healthcare systems. With commissioners turning ever more frequently to ClinRO data to evaluate and compare individual hospital performance and casemix, and funding decisions increasingly relying on these data, agreed core outcome sets (COS) are essential for the collection of standardised specialty-specific outcomes. Beyond their role in service commissioning, COS enable standardisation of outcomes in clinical studies, allowing comparisons to be drawn between similar trials as well as pooling of data for systematic reviews and metaanalyses.

Policy implications for awareness gaps in antimicrobial resistance (AMR) and antimicrobial use among commercial Nepalese poultry producers.

Background: Nepal's poultry industry has increased with a growing middle class, which has translated to an increase in antimicrobial consumption and thus a rise in antimicrobial resistance (AMR). Describing and understanding antimicrobial use practices among commercial poultry producers in Nepal may help minimize the risks of AMR development in both humans and animals and determine the effectiveness of relevant policies.

Methods: From July to August 2018, poultry farmers were randomly recruited from Nepal's Chitwan District to participate in a cross-sectional study.

Preference for infant-directed speech in preterm infants.

The current study explores the effects of exposure to maternal voice on infant sucking in preterm infants. Twenty-four preterm infants averaging 35 weeks gestational age were divided randomly into two groups. A contingency between high-amplitude sucking and presentation of maternal voice was instituted for one group while the other group served as a yoked control.

Conservation of the Low-shear Modeled Microgravity Response in Enterobacteriaceae and Analysis of the trp Genes in this Response.

Low fluid shear force, including that encountered in microgravity models, induces bacterial responses, but the range of bacteria capable of responding to this signal remains poorly characterized. We systematically analyzed a range of Gram negative Enterobacteriaceae for conservation of the low-shear modeled microgravity (LSMMG) response using phenotypic assays, qPCR, and targeted mutations. Our results indicate LSMMG response conservation across Enterobacteriacae with potential variance in up- or down-regulation of a given response depending on genus.

A series of IncQ-based reporter plasmids for use in a range of Gram negative genera.

Many studies require expression analysis of the same gene/promoter across a range of bacterial genera. However, there is currently a lack of availability of reporters based on the broad host range IncQ replicon, which is compatible with a popular improved IncP transfer system that is self-transfer defective. We report IncQ lacZ reporter plasmids with features including: (1) compatibility with IncP, IncW, and pBHR/pBBR replicons, (2) a variety of antibiotic markers (Sp-r, Sm-r, Km-r, Cm-r), (3) convenient mobilization via a novel self-transfer-defective IncP conjugation system, and (4) complete DNA sequences.

The undershoot bias: learning to act optimally under uncertainty.

Learning in stochastic environments is increasingly viewed as an important psychological ability. To extend these results from a perceptual to a motor domain, we tested whether participants could learn to solve a stochastic minimal-time task using exploratory learning. The task involved moving a cursor on a computer screen to a target.

Attention during looking and reaching as assessed by heart rate in 7(1/2)-month-old infants.

Attention mediates the acquisition and encoding of information about the world and is central to motor action. Heart rate deceleration and behavioral inhibition are sensitive indices of the attentional process, but it is unknown whether these indices are valid in the context of overt action. The current study investigated the relationship between visual attention, action, and heart rate during reaching in 7(1/2)-month-old infants.
