Thyroid dysfunction and exudative age-related macular degeneration - A longitudinal nationwide registry-based cohort study.

The association between thyroid dysfunction and exudative age-related macular degeneration (AMD) is unknown. In this Danish longitudinal nationwide registry-based cohort study we included all Danish residents aged 50-100 between 2008 and 2018. Using the Danish national registries, we studied the association between thyroid dysfunction and exudative AMD. Thyroid dysfunction was classified as two consecutive redeemed prescriptions of thyroid hormones (hypothyroidism) or anti-thyroid medication (hyperthyroidism). Exudative AMD was classified as an ICD diagnosis of AMD and a code for anti-VEGF treatment. All patients are treated for exudative AMD in a hospital in Denmark, and we therefore have complete registration of this patient group. We included 2 087 305 individuals, of which 1 072 567 (51.4%) were women; 59 318 (2.8%) had hypothyroidism, and 33 922 (1.6%) had hyperthyroidism. During a median follow-up of 11 years, 26 998 (1.3%) people developed exudative AMD. Hypothyroidism (adjusted hazard ratio [HR]: 1.17; 95% confidence interval [CI] 1.10-1.25; p < 0.001) and hyperthyroidism (HR: 1.23; 95% CI:1.13-1.34; p < 0.001) were both associated with the development of exudative AMD. The age-stratified analyses yielded similar results to the main analyses, except that the risks were exaggerated in the older part of the population. This is the first longitudinal nationwide study showing that both hypo- and hyperthyroidism are associated with an increased risk of exudative AMD. AMD is a quantitative problem in the population and our findings could have a public health impact. Further studies are needed to study the underlying mechanisms of the association.

The mental health toll among healthcare workers during the COVID-19 Pandemic in Malawi

The COVID-19 pandemic has affected the mental health of healthcare workers worldwide, with frontline personnel experiencing heightened rates of depression, anxiety, and posttraumatic stress. This mixed-methods study aimed to assess the mental health toll of COVID-19 on healthcare workers in Malawi. A cross-sectional survey utilising the Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-9), and Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) was conducted among 109 frontline healthcare workers. Additionally, in-depth interviews were conducted with 16 healthcare workers to explore their experiences and challenges during the pandemic. The results indicated a high prevalence of COVID-19-related depression (31%; CI [23, 41]), anxiety (30%; CI [22, 40]), and PTSD (25%; CI [17, 34]) among participants. Regression analysis revealed significantly higher rates of depression, anxiety, and PTSD among healthcare workers in city referral hospitals compared to district hospitals. Qualitative findings highlighted the emotional distress, impact on work and personal life, and experiences of stigma and discrimination faced by healthcare workers. The stress process model provided a valuable framework for understanding the relationship among pandemic-related stressors, coping resources, and mental health outcomes. The findings underscore the urgent need for interventions and support systems to mitigate the mental health impact of COVID-19 on frontline healthcare workers in Malawi. Policymakers should prioritise the assessment and treatment of mental health problems among this critical workforce to maintain an effective pandemic response and build resilience for future crises.

Assessing Direct and Spillover Effects of Intervention Packages in Network-randomized Studies.

Intervention packages may result in a greater public health impact than single interventions. Understanding the separate impact of each component on the overall package effectiveness can improve intervention delivery. We adapted an approach to evaluate the effects of a time-varying intervention package in a network-randomized study. In some network-randomized studies, only a subset of participants in exposed networks receive the intervention themselves. The spillover effect contrasts average potential outcomes if a person was not exposed to themselves under intervention in the network versus no intervention in a control network. We estimated the effects of components of the intervention package in HIV Prevention Trials Network 037, a Phase III network-randomized HIV prevention trial among people who inject drugs and their risk networks using marginal structural models to adjust for time-varying confounding. The index participant in an intervention network received a peer education intervention initially at baseline, then boosters at 6 and 12 months. All participants were followed to ascertain HIV risk behaviors. There were 560 participants with at least one follow-up visit, 48% of whom were randomized to the intervention, and 1,598 participant visits were observed. The spillover effect of the boosters in the presence of initial peer education training was a 39% rate reduction (rate ratio = 0.61; 95% confidence interval = 0.43, 0.87). These methods will be useful for evaluating intervention packages in studies with network features.

An open pilot trial of a behavioural intervention to reduce violence by young adults with early psychosis receiving treatment in an early intervention services setting: A protocol.

Despite the public health impact of violence among young adults with psychosis, behavioural interventions to reduce the risk of engaging in violence remain rare. For young adults with early psychosis, cognitive behavioural therapy (CBT)-based psychotherapy has efficacy in reducing impairment and improving functioning. However, no CBT-based intervention to reduce violence has been formally adapted for young adults with early psychosis. This protocol outlines the first clinical trial of a behavioural intervention to reduce violence for young adults with early psychosis. This study is set in an early intervention services (EIS) setting and seeks to adapt and pilot Psychological Intervention for Complex PTSD and Schizophrenia-Spectrum Disorder (PICASSO), a CBT-based intervention, through an iterative process utilizing mixed-methods assessments. All research will occur at OnTrackNY, the largest EIS program in the United States. This study will consist of an open pilot trial, with four EIS clinicians delivering the intervention to one to two EIS participants per round. In this mixed-methods study, both quantitative measures (acceptability, feasibility and hypothesized mediators of target outcome collected on a weekly basis) and qualitative interviews (with EIS clinicians at weeks 4, 8 and 12) will be conducted. Transcripts will be analyzed using thematic content analysis. Two to three rounds of iterative modifications are anticipated (n = 10-16 EIS participants total). Recruitment began in February 2024 and is expected to continue over a 9-12-month period. Because violent behaviour causes interpersonal disruptions such as incarceration and increased caregiver burden, an innovative intervention to reduce violence risk could have broader health impact for this vulnerable population. Adapting the PICASSO intervention to the EIS setting will optimize its acceptability and feasibility by the intended target population.

Climate change education: exploring knowledge, attitudes, and practices of medical students in a Turkish medical school

ABSTRACT Climate change presents a significant health challenge, emphasizing the need for resilient healthcare systems. This study aimed to explore medical students’ knowledge, attitudes, and practices regarding the climate-health link and their curriculum preferences. Conducted from March to June 2023 at the Medical School of Bahçeşehir University, Turkiye, the cross-sectional study utilized an online questionnaire covering demographic data and climate change-related inquiries. Participation was open to all medical students without class-based distinctions. The response rate was 53.6%, with 439 medical students included (average age: 21.8 years). The majority (74.5%) acknowledged human-induced climate change, with over 87% expressing concerns about its impact on health. Nearly 70% emphasized the importance of physicians understanding climate change’s health effects, while 45.8% perceived a lack of information in their medical education. Most students (70.0%) supported integrating climate change’s health effects into medical education, rating its importance at 7.1 on a scale of 0 to 10. Preferences included electives, team-based learning, case-based learning, problem-based learning, clinical practice in climate-sensitive diseases, and theoretical courses on climate change in basic medical sciences. This study underscores the growing awareness among medical students regarding climate change’s health impact and the need for climate-integrated medical education, emphasizing its importance in preparing future physicians for climate-related health challenges and resilient healthcare systems.

Characteristics of PM2.5 bounded carbonaceous aerosols, carbon dioxide and its stable carbon isotopes (δ13C) in rural households in northwest China: effect of different fuel combustion

In order to fully understand the carbon emission from different fuels in rural villages of China, especially in the typical atmospheric pollution areas. The characteristics of carbonaceous aerosols and carbon dioxide (CO2) with its stable carbon isotope (δ13C) were investigated in six households, which two households used coal, two households used wood as well as two households used biogas and liquefied petroleum gas (LPG), from two rural villages in Fenwei Plain from March to April 2021. It showed that the fine particulate matter (PM2.5) emitted from biogas and LPG couldn't be as lower as expected in this area. However, the clean fuels could relatively reduce the emissions of organic carbon (OC) and element carbon (EC) in PM2.5 compare to the solid fuels. The pyrolyzed carbon (OP) accounted more total carbon (TC) in coal than the other fuels use households, indicating that more water-soluble OC existed, and it still had the highest secondary organic carbon (SOC) than the other fuels. Meantime, the coal combustions in the two villages had the highest CO2 concentration of 527.6ppm and 1120.6ppm, respectively, while the clean fuels could effectively reduce it. The average δ13C values (-26.9‰) was much lighter than almost all the outdoor monitoring and similar to the δ13C values for coal combustion and vehicle emission, showing that they might be the main contributors of the regional atmospheric aerosol in this area. During the sandstorm, the indoor PM2.5 mass and CO2 were increasing obviously. The indoor cancer risk of PAHs for adults and children were greater than 1×10-6, exert a potential carcinogenic risk to human of solid fuels combustion in rural northern China. It is important to continue concern the solid fuel combustion and its health impact in rural areas.

Oral health-related quality of life in implant-supported rehabilitations: a prospective single-center observational cohort study

BackgroundOral Health-Related Quality of Life (OHRQoL) is a comprehensive concept covering daily comfort, self-esteem, and satisfaction with oral health, including functional, psychological, and social aspects, as well as pain experiences. Despite abundant research on OHRQoL related to oral diseases and hygiene, there is limited data on how patients perceive changes after implant-prosthetic rehabilitation. This study aimed to evaluate OHRQoL and aesthetic perception using OHIP-14 and VAS scales respectively, before (baseline-TB), during (provisional prostheses-TP), and after (definitive prostheses-TD) implant-prosthetic rehabilitation. It also explored the impact of biological sex, substitution numbers, and aesthetic interventions on OHRQoL and VAS scores, along with changes in OHIP-14 domains.MethodsA longitudinal prospective single-center observational cohort study was conducted with patients requiring implant-prosthetic rehabilitation. Quality of life relating to dental implants was assessed through the Italian version of Oral Health Impact Profile-14 (IOHIP-14), which has a summary score from 14 to 70. Patients’ perceived aesthetic was analyzed through a VAS scale from 0 to 100. Generalized Linear Mixed Effect Models, Linear Mixed Effect Models, and Friedman test analyzed patient responses.Results99 patients (35 males, 64 females) aged 61–74, receiving various prosthetic interventions, were enrolled. Both provisional and definitive prosthetic interventions significantly decreased the odds of a worse quality of life compared to baseline, with odds ratios of 0.04 and 0.01 respectively. VAS scores increased significantly after both interventions, with estimated increases of 30.44 and 51.97 points respectively. Patient-level variability was notable, with an Intraclass Correlation Coefficient (ICC) of 0.43. While biological sex, substitution numbers, and aesthetic interventions didn’t significantly affect VAS scores, OHRQoL domains showed significant changes post-intervention.ConclusionsThese findings support the effectiveness of implant-prosthetic interventions in improving the quality of life and perceived aesthetics of patients undergoing oral rehabilitation. They have important implications for clinical practice, highlighting the importance of individualized treatment approaches to optimize patient outcomes and satisfaction in oral health care.

Introducing the Occupational Health and Safety Potential Midpoint Impact Indicator in Social Life Cycle Assessment

Occupational health and safety (OSH) is crucial for sustainable development, recognized by corporations, the European Union, and Sustainable Development Goals. This study introduces a characterization model for OSH in the social life cycle assessment (S-LCA) to support the quantification of OHS along product supply chains and sustainable decision making. The characterization model aims to provide a practical approach for assessing OHS at the product level with actual working hours or recommends a secondary approach with monetary data, when working hours are unavailable, to calculate the Occupational Health and Safety Potential (OHSP). The developed model was tested in a theoretical case study on shirt production in Europe and globally. The case study shows that the European shirt value chain resulted in higher OHSP values than the global shirt values chain. In addition, the model shows which life cycle stages and organizations highly contributed to the OHSP results. In both approaches, the shirt production stage contributed highly. Differences in results emerged based on the calculation approach, underscoring the model’s versatility, because increasing the complexity of calculating the CFs with monetary values will affect the results based on sectorial monetary output. Additionally, the study mentions benefits to the operationalization of social impact assessment and limitations when the developed characterized model is employed. Last, this study aids in offering a tool for organizations to meet the demands of the new Corporate Sustainability Reporting Directive by quantifying and publicizing OHS data.

The effect of somatic pain and comorbid mental distress on oral health-related quality of life in orthodontic patients.

The purpose of the present study was to evaluate the prevalence of somatic pain in orthodontic patients and determine whether somatic pain contributes to worsening oral health-related quality of life (OHRQoL) through the mediating effect of psychological discomfort. Scale measurements and analyses were conducted on a cohort of 769 orthodontic outpatients, encompassing Patient Health Questionnaire-15-pain (PHQ-15-P), Hua-Xi Emotional-Distress Index (HEI), Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), and Oral Health Impact Profile-14 (OHIP-14). Among the respondents, 56.3% (N = 433) reported somatic pain and 20.0% (N = 154) had mental discomfort based on PHQ-15-P and HEI scores. Patients with somatic pain symptoms had significantly higher scores of HEI and OHIP-14 (P < 0.001), and higher PHQ-15-P and HEI scores emerged as statistically significant predictors of lower OHIP-14 scores (P < 0.001). HEI scores which assessed anxiety and depression partially mediated the correlation between PHQ-15-P and OHIP-14 scores, of which anxiety accounted for 52.9% of the overall mediation effect, dominating the indirect effect. Orthodontic patients reporting somatic pains were at a significantly higher risk of worsening OHRQoL during treatment, and this adverse effect is partially mediated by anxiety and depression. Our findings highlight the necessity for the assessment of general health and mental well-being during orthodontic interventions. To prevent delays in treating general disorders and the potential failure of orthodontic treatments, we encourage increased attentiveness towards patients with somatic symptoms and consideration of the adverse effects of comorbid mental distress.

Bleaching efficacy of in-office dental bleaching with different application protocols: a single-blind randomized controlled trial.

This randomized controlled trial aimed to evaluate the equivalence in the color change, adverse effects, self-perception (AS) and the impact on oral condition (IO) of participants submitted to different application protocols of in-office dental bleaching. 165 participants were bleached with a 35% hydrogen peroxide gel (Total Blanc Office One-Step, DFL), according to the following protocols: (1) 2 applications of 20-min each (2 × 20min); (2) 1 × 40-min and; (3) 1 × 30-min. The color change was evaluated with the Vita Easyshade spectrophotometer, Vita Classical and Vita Bleachedguide scales. The intensity and risk of tooth sensitivity (TS) and gingival irritation (GI) were recorded using a 0-10 visual analogue scale (VAS). AS and IO was assessed before and after the bleaching procedure using the Orofacial Aesthetic Scale and Oral Health Impact Profile-14, respectively. Equivalent color change were observed (p < 0.001), with no significant difference between groups. The group 2 × 20min presented the highest risk of TS (76%, 95% CI 63 to 85), compared to the 1 × 30min (p < 0.04). The intensity of TS and GI and the risk of GI was similar between groups (p > 0.31). Irrespectively of the group (p = 0.32), significant improvements were observed for all items of AS and IO after bleaching (p < 0.02). The 1 × 30min protocol produced equivalent color change to the other bleaching protocols with reduced risk of TS and shorter application time. A more simplified application regimen of a single application of 30min yields effective bleaching and patient satisfaction while minimizing undesirable side effects and improving patient satisfaction.

Care seeking for childhood illnesses in rural Mtwara, south-east Tanzania: a mixed methods study.

Care seeking was assessed in preparation for a study of the health impact of novel design houses in rural Mtwara, Tanzania. A total of 578 residents of 60 villages participated in this mixed-methods study from April to August 2020. Among them, 550 participated in a healthcare-seeking survey, 17 in in-depth interviews and 28 in key informant interviews. The decision to seek care was based on symptom severity (95.4% [370]). Caregivers first visited non-allopathic healthcare providers or were treated at home, which led to delays in seeking care at healthcare facilities. More than one-third (36.0% [140]) of respondents took >12 h seeking care at healthcare facilities. The majority (73.0% [282]) visited healthcare facilities, whereas around one-fifth (21.0% [80]) sought care at drug stores. Treatment costs deterred respondents from visiting healthcare facilities (61.4% [338]). Only 10 (3.6%) of the households surveyed reported that they were covered by health insurance. Quality of care, related to institutional factors, impacts timely care seeking for childhood illnesses in Mtwara, Tanzania. Ensuring accessibility of facilities is therefore not sufficient.

Accelerating implementation of adolescent digital health prevention programs: analysis of insights from Australian stakeholders

BackgroundChronic disease risk factors are increasing amongst adolescents, globally. Digital health prevention programs, which provide education and information to reduce chronic disease risk factors need to be equitable and accessible for all. For their success, multiple highly engaged stakeholders should be involved in development and implementation. This study aimed to evaluate stakeholders’ support for, and perspectives on potential public health impact of digital health prevention programs for adolescents and potential pathways for future implementation.MethodsQualitative semi-structured online interviews with stakeholders. Stakeholder mapping identified key individuals, groups and organizations across Australia that may influence the implementation of digital health prevention programs for adolescents. Recorded and transcribed interviews were analyzed within the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) Framework, using deductive content analysis.FindingsNineteen interviews were conducted in 2023 with stakeholders from government, health, non-government organizations, youth services, education, community settings and others. Four overarching themes were identified: (i) existing digital health initiatives are not fit for purpose; (ii) the co-creation of digital health prevention programs is critical for successful implementation; (iii) digital health prevention programs must address equity and the unique challenges raised by technology and; (iv) system level factors must be addressed.InterpretationStakeholders broadly supported digital health prevention programs, yet raised unique insights to ensure that future programs create public health impact by improving chronic disease risk factors among adolescents. These insights can be applied in future development of digital health prevention programs for adolescents to strengthen widespread implementation.

Assessing public health implications of free trade agreements: The comprehensive and progressive Trans‐Pacific Partnership Agreement

AbstractIn 2016, the United Kingdom voted to exit the European Union, which was surrounded by political and social uncertainty. The United Kingdom now negotiates its own trade agreements, and in March 2023, it agreed to join the Comprehensive and Progressive Trans‐Pacific Partnership Agreement (CPTPP). A health impact assessment (HIA) was undertaken in 2022–23 to predict the potential impact of the CPTPP on the health and well‐being of the Welsh Population. This paper explores the HIA findings and highlights the value of the approach in engaging with stakeholders and informing policymakers. This HIA followed a standard five‐step approach which involved a literature review to identify potential health impacts, qualitative interviews with cross‐sectoral stakeholders and the development of a community health profile. The HIA identified potential impacts across the wider determinants of health and specific vulnerable population groups. Investor state dispute settlement mechanisms, economic uncertainty and loss of regulatory policy space were identified as key pathways for health impacts. The findings have been beneficial in informing decision‐makers to prepare for the CPTPP in Wales using an evidence‐informed approach. This work has demonstrated the value of a HIA approach that uses a transparent process to mobilise a wide range of evidence, resulting in transferrable learning.

Abstract PO1-09-10: County-level Social Vulnerability and Survival among Women with Inflammatory Breast Cancer

Abstract Purpose: Inflammatory breast cancer (IBC) is an aggressive form of breast cancer with a poor overall prognosis compared to other forms of breast cancer. Advances in treatment have contributed to improvement in IBC survival rates in recent years, yet disparities in outcomes persist. It is unclear whether social determinants of health impact IBC prognosis independent of access to quality cancer care. Thus, the aim of this study was to examine whether the US county-level social vulnerability index (SVI) was associated with IBC stage at diagnosis and overall survival (OS) among women with IBC treated at a single institution. Methods: Patients enrolled in the IBC registry at Dana-Farber Cancer Institute (DFCI) were included in this study. We linked participant’s residential zip codes to the 2020 CDC’s county-level SVI, which is calculated from 15 social determinants of health attributes from the American Community Survey including socioeconomic status, household composition, language and minority status, and housing and transportation factors. The SVI value reflects the percentile of counties in the nation that are less vulnerable than the county of interest. We assessed associations between SVI and stage at diagnosis using t-tests. Kaplan-Meier curves and log-rank tests were used to assess survival across SVI quartiles based on distribution (1st [least vulnerable] and 4th [most vulnerable]). Using hierarchical logistic regression models and Cox proportional hazards models with mixed effects incorporating cluster-specific random effects that modify the baseline hazard function, we assessed whether SVI is associated with the presence of de novo metastatic disease and OS in IBC. Results: A total of 586 women (86% White) enrolled in the IBC registry at DFCI between 1986 and 2021 were included in this study. Of these, 69.1% had stage III and 30.9% had de novo metastatic disease. 280 deaths occurred in the study population over a mean follow-up of 4.1 years. SVI for the counties where study participants resided ranged from 2.6% to 95.8% (median=34.2%). The mean SVI did not significantly differ according to stage at diagnosis (41.6% in non-metastatic and 40.8% in metastatic at presentation; p=0.70). OS did not significantly differ across SVI quartiles (p-value=0.63). In the age-adjusted models, the SVI was not associated with the presence of de novo metastatic disease (odds ratio (OR (95% CI)=0.99 (0.84, 1.16)) or OS (HR (95% CI)=0.79 (0.46, 1.33). Conclusions: Our findings that residing in socially vulnerable US counties is not associated with the presence of de novo metastatic disease or IBC survival among a subset of women accessing high-quality cancer care suggest that improving access to quality cancer care may overcome underlying socioeconomic factors that contribute to disparities in IBC outcomes. Future studies are needed to confirm these findings in other settings.

Abstract PO2-09-10: Addressing Breast Cancer Disparities: Co-Creating Digital Interventions with Patients, Navigators &amp; the Community to Address Social Determinants of Health in the Memphis Statistical Area

Abstract Background: The Memphis Statistical Area, which covers counties in Arkansas, Mississippi, and Tennessee, leads in disparities in mortality rates between Black breast cancer patients compared to White counterparts1. Urban Health Education &amp; Support Services (UHESS), in partnership with RabbleHealth, and West Cancer Center &amp; Research Institute (WCCRI), initiated a solutions-oriented, community-based scalable initiative in January 2023 to measurably address social determinants of health (SDOH), which often drive cancer inequities that disproportionately impact individuals of marginalized communities. By leveraging a community-driven, co-creation sustainable approach, the team sought to measurably improve breast cancer equality utilizing digital enablement and the knowledge of local breast cancer survivors and leading healthcare professionals, including navigators. Methods: A four-phase approach was leveraged to 1. improve access to locally available breast cancer services in communities that are traditionally underserved and 2. measure the public health impact against root causes of breast inequities (i.e., care pathway metrics), and 3. create a repeatable, scalable model to expand to other underserved communities. In Phase 1, UHESS leveraged the Mid-South Regional Breast Cancer Coalition, which convenes ten local breast cancer patient advocacy organizations, to recruit focus groups for co-creation throughout all phases of the initiative. The working group consisted of eight representatives from a variety of Memphis-based cancer organizations, faith-based organizations, navigator programs, and WCCRI. This phase centered around establishing trust with the local patient advocacy community. In Phase 2, an initial patient survey was circulated to identify key resources that reduce health inequities and barriers to access. Human-centered design facilitators supported a series of Listen &amp; Learn workshops with patients to convey root causes of gaps in access to relevant services and with navigators to understand professional needs of navigators and scale the ability improve patient access to resources. To co-create a solution, facilitated patient and navigator workshops were held in Phase 3 to gather patient-centric user experience and design enhancements for a digital patient engagement app. These requirements as well as navigator-defined metrics needs were digitized and organized by SDoH. Phase 4, the Deploy &amp; Measure phase, will begin in September of 2023 and the community-based deployment model focuses on three drivers including: (a) embedding within navigator workflow, (b) activating faith-based organizations, and (c) leveraging societies. Health equity performance data will be analyzed weekly to rapidly target those ZIP codes with the greatest need. Results: Co-design efforts included over 50 members of the Greater Memphis community and final initiative results will be presented at the meeting. Planning for further research regarding community impact and model scalability is already underway. Conclusion: By leveraging a community-driven, co-creation sustainable approach, this model enables a better way to measurably improve breast cancer equality utilizing digital enablement and the knowledge of local breast cancer survivors and leading healthcare professionals, including navigators.

Patient-reported outcomes after oral cancer reconstructions with radial and ulnar forearm-free flaps.

This study aimed to evaluate patient-reported quality of life and incidence of decision regret in patients undergoing radial (RFFF) and ulnar forearm-free flaps (UFFF) reconstruction. Patients undergoing either RFFF or UFFF were assessed with the University of Washington Quality of Life (UW-QOL) and Oral Health Impact Profile (OHIP-14) questionnaires, and the Decision Regret Scale (DRS), both before and at least 12 months post-reconstruction. In total, 40 RFFF and 40 UFFF were included. Harvesting time was longer in RFFF (p = 0.043), and the donor-site defect was significantly larger in RFFF than in UFFF (p = 0.044). Patients with UFFF scored better UW-QOL in the appearance, pain, activity, mood, and social functioning domains (p < 0.05). However, the RFFF group excelled in swallowing and chewing domains. The DRS score revealed a significant difference between RFFF and UFFF, with scores of 36.26 versus 27.36, respectively. Moreover, the mean DRS score reduced at 12 months compared with 6 months, significantly superior for UFFF. Oral cancer patients reconstructed with UFFF exhibited a better appearance, social domain, and mild decision regret compared with RFFF, indicating that the UFFF may contribute to improving postoperative quality of life in oral cancer patients.

Adjuvanted Vaccine to Prevent Respiratory Syncytial Virus in Adults Ages 60 Years and Older

Respiratory syncytial virus (RSV) is a prevalent cause of acute lower respiratory tract illness that disproportionately affects older adults, young children, and infants, which can lead to hospitalizations and death. The health impact on the elderly and infants accentuates the need for effective preventive strategies. Arexvy is the first approved vaccine to prevent lower respiratory tract illness caused by RSV in older adults ages 60 and older. It contains recombinant respiratory syncytial virus glycoprotein F stabilized in the prefusion conformation. Arexvy offers approximately 83% protection in adults and appears to maintain effectiveness for up to two RSV seasons. The vaccine was generally well tolerated in clinical trials, with the most frequently observed and reported adverse events being mild to moderate injection site pain, fatigue, myalgia, headache, and arthralgia. This article includes a description of Arexvy, the target population, contraindications, side effects, and clinical implications when considering the use of this vaccine.

Assessment of Patient Satisfaction and Oral Health-Related Quality of Life Following Full Mouth Rehabilitation with Implant-Supported Prostheses

ABSTRACT Background: The concept of success is typically established by the researcher or the practitioner rather than the patient, who has the greatest stake in the outcome of the prosthodontics therapy. Aim: To assess patient satisfaction and oral health-related quality of life (OHRQoL) in following full mouth rehabilitation with implant-supported prostheses (ISP). Methods and Materials: Thirty-two patients who underwent full mouth rehabilitation with ISP were included in this study. The Oral Health Impact Profile-14 (OHIP-14) questionnaire was used for the assessment of patient satisfaction and OHRQoL following full mouth rehabilitation with ISP. Results: The functional limitation among study participants before, 1 month, and 3 months after ISP was 2.1 ± 1.3, 1.5 ± 0.8, and 1.4 ± 0.9, respectively. There was a significant reduction in functional limitation, psychological disability, and social disability before and 3 months after ISP. Conclusion: There is a significant improvement in patient satisfaction and OHRQoL in following full mouth rehabilitation with ISP.

Risk-based public health impact assessment for drinking water contamination emergencies.

Chemical spills in surface waters pose a significant threat to public health and the environment. This study investigates the public health impacts associated with organic chemical spill emergencies and explores timely countermeasures deployable by drinking water facilities. Using a dynamic model of a typical multi-sourced New England drinking water treatment facility and its distribution network, this study assesses the impacts of various countermeasure deployment scenarios, including source switching, enhanced coagulation via poly‑aluminum chloride (PACl), addition of powdered activated carbon (PAC), and temporary system shutdown. This study reveals that the deployment of multiple countermeasures yields the most significant reduction in total public health impacts, regardless of the demand and supply availability. With the combination PAC deployed first with other countermeasures proving to be the most effective strategies, followed by the combination of facility shutdowns. By understanding the potential public health impacts and evaluating the effectiveness of countermeasures, authorities can develop proactive plans, secure additional funding, and enhance their capacity to mitigate the consequences of such events. These insights contribute to safeguarding public health and improving the resilience of drinking water systems in the face of the ever-growing threat of chemical spills.
