Associations Between Social Determinants of Health and Outcomes of Chronic Medical Conditions.

Social determinants of health, such as food insecurity, can significantly impact patient welfare, potentially increasing the prevalence of chronic illnesses while hindering their management, as shown in previous data collected by the National Health and Nutrition Examination Survey. This study aimed to investigate the association between food insecurity and other social determinants of health with hyperlipidemia, type 2 diabetes mellitus (T2DM), and hypertension. To that end, self-reported data on food security from clinical encounters and biological data from medical records were collected. This study utilized electronic medical record data from 349 patients aged between 18 and 85 years who answered two standard food insecurity screening questions. Each patient's current diagnoses and lab values, including blood pressure, fasting low-density lipoprotein (LDL) cholesterol, and hemoglobin A1c (HbA1c), were then collected. Among patients facing food insecurity (n = 48), 55% were diagnosed with hypertension (p = 0.019), 45% with hyperlipidemia, and 27% with T2DM (p = 0.005). By comparison, these values for food-secure patients were 39%, 54%, and 13%, respectively (n = 301, p > 0.05). Regarding control of these chronic illnesses, hypertension (defined as blood pressure >135/85 mmHg per American Academy of Family Physicians (AAFP) guidelines) was observed in 12% of food-secure patients (n = 301, p > 0.05) and 42% of food-insecure patients (n = 48, p = 0.0204), whereas differences in control of hyperlipidemia and T2DM were insignificant. These results suggest that food-insecure patients are more likely to be diagnosed with hypertension and T2DM but are less likely than food-secure patients to be diagnosed with hyperlipidemia. Consistent with previous research, this study highlights the potentially increased health risks for patients experiencing food insecurity and calls for further efforts to screen patients for social determinants of health.

Unlocking the World of Travel for Individuals With Intellectual and Developmental Disabilities.

This editorial explores the challenges faced by families with individuals with intellectual and developmental disabilities (IDD) when it comes to travel, drawing parallels with the difficulties experienced in attending routine doctor's appointments. The disruptions to routine, preparation of supplies, and the fear of unfamiliar environments often make travel seem like an unattainable dream for these families. Despite these challenges, some families showcase resilience and determination, managing to travel with their loved ones. The article emphasizes the inconsistency in experiences across families due to varying levels of cognition, adaptive functioning, financial means, and available support. It discusses the additional complications for families dealing with medical procedures, the scrutiny of strangers, and financial difficulties. The article suggests the crucial role of primary care physicians in facilitating travel for these families by performing pre-travel medical assessments, consulting social workers, and preparing comprehensive emergency plans. It proposes the need for collaboration between governments, the tourism industry, advocacy groups, and the community to address these challenges. Ultimately, the article advocates for the empowerment of families with IDD individuals to enjoy the world as tourists, with the support of their primary care providers.

Pulpotomy for the Management of Irreversible Pulpitis in Mature Teeth (PIP): a feasibility study.

BACKGROUND: Progression of dental caries can result in irreversible pulpal damage. Partial irreversible pulpitis is the initial stage of this damage, confined to the coronal pulp whilst the radicular pulp shows little or no sign of infection. Preserving the pulp with sustained vitality and developing minimally invasive biologically based therapies are key themes within contemporary clinical practice. However, root canal treatment involving complete removal of the pulp is often the only option (other than extraction) given to patients with irreversible pulpitis, with substantial NHS and patient incurred costs. The European Society of Endodontology's (ESE 2019) recent consensus statement recommends full pulpotomy, where the inflamed coronal pulp is removed with the goal of keeping the radicular pulp vital, as a more minimally invasive technique, potentially avoiding complex root canal treatment. Although this technique may be provided in secondary care, it has not been routinely implemented or evaluated in UK General Dental Practice. METHOD: This feasibility study aims to identify and assess in a primary care setting the training needs of general dental practitioners and clinical fidelity of the full pulpotomy intervention, estimate likely eligible patient pool and develop recruitment materials ahead of the main randomised controlled trial comparing the clinical and cost-effectiveness of full pulpotomy compared to root canal treatment in pre/molar teeth of adults 16 years and older showing signs indicative of irreversible pulpitis. The feasibility study will recruit and train 10 primary care dentists in the full pulpotomy technique. Dentists will recruit and provide full pulpotomy to 40 participants (four per practice) with indications of partial irreversible pulpitis. DISCUSSION: The Pulpotomy for the Management of Irreversible Pulpitis in Mature Teeth (PIP) study will address the lack of high-quality evidence in the treatment of irreversible pulpitis, to aid dental practitioners, patients and policymakers in their decision-making. The PIP feasibility study will inform the main study on the practicality of providing both training and provision of the full pulpotomy technique in general dental practice.

The immunomodulatory effects of social isolation in mice are linked to temperature control.

Living in isolation is considered an emerging societal problem that negatively affects the physical wellbeing of its sufferers in ways that we are just starting to appreciate. This study investigates the immunomodulatory effects of social isolation in mice, utilising a two-week program of sole cage occupancy followed by the testing of immune-inflammatory resilience to bacterial sepsis. Our results revealed that mice housed in social isolation showed an increased ability to clear bacterial infection compared to control socially housed animals. These effects were associated with specific changes in whole blood gene expression profile and an increased production of classical pro-inflammatory cytokines. Interestingly, equipping socially isolated mice with artificial nests as a substitute for their natural huddling behaviour reversed the increased resistance to bacterial sepsis. Together these results suggest that the control of body temperature through social housing and huddling behaviour are important factors in the regulation of the host immune response to infection in mice and might provide another example of the many ways by which living conditions influence immunity.

Commonly used terminology in oral surgery and oral medicine: the patient's perspective.

Introduction Dentistry is progressing into person-centred care and away from a paternal approach. Effective verbal and written communication are crucial to allow this collaboration; however, misunderstanding of terminology can lead to confusion, poor decision-making and poor health outcomes.Methods A voluntary questionnaire with multiple-choice and short-answer questions was given to patients attending the NHS Lothian Oral Surgery and Oral Medicine Department over two weeks; 137 were completed. Eighteen terms were assessed, including: ulcer, local anaesthetic, impacted tooth, radiograph, sedation, biopsy, mucosa and benign. Exclusion criteria were non-English speakers who required a translator.Results The multiple-choice questions revealed that terms such as 'blister' and 'local anaesthetic' are relatively well understood. Other terms, such as mucosa, were poorly understood. Over a third of patients confused 'sedation' with general anaesthetic. Short-answer questions revealed a wide range of answers. 'Biopsy' and 'radiograph' were generally better understood compared to other terms. Demographics, educational background and English as a first language appeared to have an influence on understanding.Conclusion Patients had a varied understanding of terminology. Incorrect interpretation of words may lead to ill-informed decision-making or unnecessary concern. It is essential that challenging terminology is identified and explained at an understandable level.

'Childrenese': A Pilot Survey on the Choice of Language in a Paediatric Dental Setting.

To ensure good communication with paediatric patients, members of the dental team typically avoid dental jargon by using appropriate substitution of words. This language of word replacement is sometimes termed 'Childrenese'. This survey was carried out to collect a formulary of perceived effective and ineffective word replacements from paediatric dental team members. It assesses the impact of factors such as age and gender on the respondents' word choice. The formulary aims to aid general dental practitioners in communicating with paediatric dental patients.

Oxidative Stress and Inflammation Induced by Environmental and Psychological Stressors: A Biomarker Perspective.

SIGNIFICANCE: The environment can elicit biological responses such as oxidative stress (OS) and inflammation as a consequence of chemical, physical, or psychological changes. As population studies are essential for establishing these environment-organism interactions, biomarkers of OS or inflammation are critical in formulating mechanistic hypotheses. Recent Advances: By using examples of stress induced by various mechanisms, we focus on the biomarkers that have been used to assess OS and inflammation in these conditions. We discuss the difference between biomarkers that are the result of a chemical reaction (such as lipid peroxides or oxidized proteins that are a result of the reaction of molecules with reactive oxygen species) and those that represent the biological response to stress, such as the transcription factor NRF2 or inflammation and inflammatory cytokines. CRITICAL ISSUES: The high-throughput and holistic approaches to biomarker discovery used extensively in large-scale molecular epidemiological exposome are also discussed in the context of human exposure to environmental stressors. FUTURE DIRECTIONS: We propose to consider the role of biomarkers as signs and to distinguish between signs that are just indicators of biological processes and proxies that one can interact with and modify the disease process.

A novel activation mechanism of avian influenza virus H9N2 by furin.

Avian influenza virus H9N2 is prevalent in waterfowl and has become endemic in poultry in Asia and the Middle East. H9N2 influenza viruses have served as a reservoir of internal genes for other avian influenza viruses that infect humans, and several cases of human infection by H9N2 influenza viruses have indicated its pandemic potential. Fortunately, an extensive surveillance program enables close monitoring of H9N2 influenza viruses worldwide and has generated a large repository of virus sequences and phylogenetic information. Despite the large quantity of sequences in different databases, very little is known about specific virus isolates and their pathogenesis. Here, we characterize a low-pathogenicity avian influenza virus, A/chicken/Israel/810/2001 (H9N2) (Israel810), which is representative of influenza virus strains that have caused severe morbidity and mortality in poultry farms. We show that under certain circumstances the Israel810 hemagglutinin (HA) can be activated by furin, a hallmark of highly pathogenic avian influenza virus. We demonstrate that Israel810 HA can be cleaved in cells with high levels of furin expression and that a mutation that eliminates a glycosylation site in HA(1) allows the Israel810 HA to gain universal cleavage in cell culture. Pseudoparticles generated from Israel810 HA, or the glycosylation mutant, transduce cells efficiently. In contrast, introduction of a polybasic cleavage site into Israel810 HA leads to pseudoviruses that are compromised for transduction. Our data indicate a mechanism for an H9N2 evolutionary pathway that may allow it to gain virulence in a distinct manner from H5 and H7 influenza viruses.

PA residues in the 2009 H1N1 pandemic influenza virus enhance avian influenza virus polymerase activity in mammalian cells.

The 2009 pandemic influenza virus (pH1N1) is a swine-origin reassortant containing human, avian, and swine influenza genes. We have previously shown that the polymerase complex of the pH1N1 strain A/California/04/2009 (Cal) is highly active in mammalian 293T cells, despite the avian origin of both its PA and PB2. In this study, we analyzed the polymerase residues that are responsible for high pH1N1 polymerase activity in the mammalian host. Characterization of polymerase complexes containing various combinations of Cal and avian influenza virus A/chicken/Nanchang/3-120/01 (H3N2) (Nan) by reporter gene assay indicates that Cal PA, but not PB2, is a major contributing factor to high Cal polymerase activity in 293T cells. In particular, Cal PA significantly activates the otherwise inactive Nan polymerase at 37 and 39°C but not at the lower temperature of 34°C. Further analysis using site-directed mutagenesis showed that the Cal PA residues 85I, 186S, and 336M contribute to enhanced activity of the Cal polymerase. Recombinant A/WSN/33 (H1N1) (WSN) viruses containing Nan NP and polymerase (PA, PB1, PB2) genes with individual mutations in PA at residues 85, 186, and 336 produced higher levels of viral protein than the virus containing wild-type (WT) Nan PA. Interestingly, compared to the WT, the virus containing the 85I mutation grew faster in human A549 cells and the 336M mutation most significantly enhanced pathogenicity in a mouse model, among the three PA mutations tested. Our results suggest that multiple mutations in PA, which were rarely present in previous influenza isolates, are involved in mammalian adaptation and pathogenicity of the 2009 pH1N1.
