Biocompatibility, Surface Morphology, and Bacterial Load of Dental Implant Abutments following Decontamination Protocols: An In-Vitro Study.

The long-term success of dental implant rehabilitation depends significantly on proper peri-implant soft tissue integration. Therefore, decontamination of abutments prior to their connection to the implant is beneficial to enhance soft tissue attachment and to aid in maintaining marginal bone around the implant. Consequently, different implant abutment decontamination protocols were evaluated regarding biocompatibility, surface morphology, and bacterial load. The protocols evaluated were autoclave sterilization, ultrasonic washing, steam cleaning, chlorhexidine chemical decontamination, and sodium hypochlorite chemical decontamination. The control groups included: (1) implant abutments prepared and polished in a dental lab without decontamination and (2) unprepared implant abutments obtained directly from the company. Surface analysis was performed using scanning electron microscopy (SEM). Biocompatibility was evaluated using XTT cell viability and proliferation assays. Biofilm biomass and viable counts (CFU/mL) (n = 5 for each test) were used for surface bacterial load evaluation. Surface analysis revealed areas of debris and accumulation of materials, such as iron, cobalt, chromium, and other metals, in all abutments prepared by the lab and with all decontamination protocols. Steam cleaning was the most efficient method for reducing contamination. Chlorhexidine and sodium hypochlorite left residual materials on the abutments. XTT results showed that the chlorhexidine group (M = 0.7005, SD = 0.2995) had the lowest values (p < 0.001) (autoclave: M = 3.6354, SD = 0.1510; ultrasonic: M = 3.4077, SD = 0.3730; steam: M = 3.2903, SD = 0.2172; NaOCl: M = 3.5377, SD = 0.0927; prep non-decont.: M = 3.4815, SD = 0.2326; factory: M = 3.6173, SD = 0.0392). Bacterial growth (CFU/mL) was high in the abutments treated with steam cleaning and ultrasonic bath: 2.93 × 109, SD = 1.68 × 1012 and 1.83 × 109, SD = 3.95 × 1010, respectively. Abutments treated with chlorhexidine showed higher toxicity to cells, while all other samples showed similar effects to the control. In conclusion, steam cleaning seemed to be the most efficient method for reducing debris and metallic contamination. Bacterial load can be reduced using autoclaving, chlorhexidine, and NaOCl.

A historical review of pain disparities research: Advancing toward health equity and empowerment.

BACKGROUND AND PURPOSE: This theory-guided review draws on 30 years of published data to examine and interrogate the current and future state of pain disparities research. METHODS: Using the Hierarchy of Health Disparity Research framework, we synthesize and present an overview of "three generations" of pain disparities scholarship, while proposing directions for adopting a "fourth generation" that redefines, explains, and theorizes future pain disparities research in a diverse society. DISCUSSION: Prior research has focused on describing the scope of disparities, and throughout the historical context of human existence, racialized groups have been subjected to inadequate pain care. It is imperative that research not only illuminates existing problems but also provides solutions that can be implemented and sustained across varying social milieus. CONCLUSION: We must invest in new theoretical models that expand on current perspectives and ideals that position all individuals at the forefront of justice and equity in their health.

Leveraging community health workers in extending pediatric telebehavioral health care in rural communities: Evaluation design and methods.

OBJECTIVE: The pandemic exacerbated and intensified pediatric behavioral health and access needs in rural and underserved areas due to long-standing workforce shortages, lack of resources, and multigenerational poverty and trauma. Kansas is a predominantly rural and frontier state with 94% of counties designated as mental health professional shortage areas. INNOVATION: The Telehealth ROCKS (THR) program is among the first of its kind to increase the behavioral health workforce capacity by integrating trained school-based community health workers (CHWs) directly into rural communities. CHWs facilitate the coordination of behavioral health appointments and access to social determinants of health needs. METHODS AND RESULTS: We plan to assess the implementation, clinical outcomes, quality of care, and access to care through a mixed-methods design to evaluate the process and impact of expanding the rural behavioral health workforce via CHWs. Preliminary program data suggest CHWs have supported over 90 students/families around social determinants of health in the first 6 months. CONCLUSION: The THR program aims to bring childserving systems of care together, cultivate relationships with rural communities, empower and increase workforce capacity in health care and education, and build trust to enhance acceptance and thus program sustainability.

The Intersection of Pain Outcomes and Social Isolation Among African Americans.

There is increasing evidence suggesting the influence social isolation has on health outcomes and mental well-being. Chronic medical conditions, such as pain, have been shown to impact social relationships and isolation among majority populations, but there is little evidence documenting this relationship among African Americans. To address this lack of scholarly work, the current study aimed to examine subjective and objective social isolation, pain interference with daily life, and problems with pain in a sample of African American adults 18 + years of age. Taken from the National Survey of American Life: Coping with Stress in the 21st Century (NSAL), results showed that participants who were objectively isolated from family only were more likely to have a chronic health problem that was associated with increased pain. Data further showed that those reporting subjective isolation from both family and friends experienced greater interference from pain than those who were not isolated from family and friends. Findings from this study acknowledge a larger issue that addresses the impact social isolation has on health, quality of life, and general well-being. Recognizing the influence of such may allow systems to acknowledge the determinants that perpetuate social isolation, while still recognizing the needs of marginalized groups.

Palliative Care Practice During the COVID-19 Pandemic: A Descriptive Qualitative Study of Palliative Care Clinicians.

CONTEXT: COVID-19 created unprecedented demand for palliative care at a time when in-person communication was highly restricted, straining efforts to care for patients and families. OBJECTIVES: To qualitatively explore the challenges presented by the COVID-19 pandemic from the perspective of palliative care clinicians. Specifically we sought to: 1) Describe the strategies adopted by palliative care clinicians to cope with new challenges including patient and clinician isolation, prognostication of an emergent disease, and rapidly rising numbers of severely ill patients; 2) Identify additions or adjustments to in-person and system-related palliative care training, methods, and tools made during pandemics. METHODS: This descriptive qualitative study utilized a thematic approach for data analysis of individual, semi-structured interviews with palliative care clinicians (n = 25). Codes, categories, and emerging themes were identified through an iterative, comparative method. Methods align with the Consolidated Criteria for Reporting Qualitative Research (COREQ) RESULTS: A theme of "Expanding the reach of palliative care for today and the future" was identified with three subthemes: 1) Redefining attitudes and hardship due to collective uncertainty, 2) Breaking with the past towards integrated concept of palliative care, and 3) Building capacity through primary palliative care training. CONCLUSION: COVID-19 forced hospital systems to consider the inclusion of palliative care in unforeseen ways due to an uncontrollable, unpredictable disease. Faced with unprecedented uncertainty, palliative care clinicians utilized strategies for integration and innovation across hospitals, particularly in intensive care units and emergency departments. A need to build capacity through increased primary palliative care access and training was identified.
