ABSTRACT

OBJECTIVES: This systematic review aimed to evaluate the effectiveness of psychological interventions in improving oral health behaviors and status among adolescents. SOURCES: A comprehensive search was conducted in the following six electronic databases, PubMed, Ovid Medline, Ovid Embase, Cochrane Library, APA PsycINFO (ProQuest) and Web of Science. STUDY SELECTION: The PICO format was used to select eligible studies. Population was adolescents 12 to 18 years old. Intervention was psychological interventions based on psychological theories or models. Comparison was conventional oral health education or negative control. Outcomes were oral health-related behaviors, oral health status, oral health-related quality of life (OHRQoL), self-efficacy and psychological cognitive factors. The risk of bias tool used was RoB 2. DATA: Sixteen papers on 14 studies met the inclusion criteria. The studies were conducted in school or clinic settings. Regarding risk of bias, most studies had some concerns and the others had a high risk. The psychological interventions improved adolescent's oral hygiene and periodontal status in the short-term (up to 6 months), with the overall SMD = -0.97 (-1.45, -0.49) in plaque level and SMD = -1.18 (-2.32, -0.04) in periodontal status. No significant difference in plaque level was found in the long-term (12 to 24 months), with the overall SMD = -0.31 (-0.64, 0.02). There was improvement in OHRQoL in the short-term, with the overall SMD = 1.04 (0.34, 1.73). Additionally, significant differences were found regarding self-efficacy, oral health-related behaviors (tooth brushing and dental flossing) and psychological cognitive factors between the intervention group and control group (all p < 0.05) in the short-term. Due to the heterogeneity of the studies, meta-analysis could not be conducted in the above three outcome measurements. CONCLUSIONS: Low certainty of evidence shows that psychological intervention is effective in improving adolescents' oral hygiene in short-term. In addition, very low certainty of evidence was found in improving periodontal status, self-efficacy, oral health-related behaviors, psychological cognitive factors, and OHRQoL in short-term. CLINICAL SIGNIFICANCE: By targeting the psychological process and cognitive factors of oral health-related behaviors among adolescents, psychological interventions have the potential to improve oral health behaviours and promote oral health among adolescents. Implementing evidence-based psychological interventions in dental practice can lead to more comprehensive and effective dental care for adolescents.

ABSTRACT

In the context of the virosphere, viral particles can compete for host cells. In this scenario, some viruses block the entry of exogenous virions upon infecting a cell, a phenomenon known as superinfection inhibition. The molecular mechanisms associated with superinfection inhibition vary depending on the viral species and the host, but generally, blocking superinfection ensures the genetic supremacy of the virus's progeny that first infects the cell. Giant amoeba-infecting viruses have attracted the scientific community's attention due to the complexity of their particles and genomes. However, there are no studies on the occurrence of superinfection and its inhibition induced by giant viruses. This study shows that mimivirus, moumouvirus, and megavirus, exhibit different strategies related to the infection of Acanthamoeba. For the first time, we have reported that mimivirus and moumouvirus induce superinfection inhibition in amoebas. Interestingly, megaviruses do not exhibit this ability, allowing continuous entry of exogenous virions into infected amoebas. Our investigation into the mechanisms behind superinfection blockage reveals that mimivirus and moumouvirus inhibit amoebic phagocytosis, leading to significant changes in the morphology and activity of the host cells. In contrast, megavirus-infected amoebas continue incorporating newly formed virions, negatively affecting the available viral progeny. This effect, however, is reversible with chemical inhibition of phagocytosis. This work contributes to the understanding of superinfection and its inhibition in mimivirus, moumouvirus, and megavirus, demonstrating that despite their evolutionary relatedness, these viruses exhibit profound differences in their interactions with their hosts.IMPORTANCESome viruses block the entry of new virions upon infecting a cell, a phenomenon known as superinfection inhibition. Superinfection inhibition in giant viruses has yet to be studied. This study reveals that even closely related viruses, such as mimivirus, moumouvirus, and megavirus, have different infection strategies for Acanthamoeba. For the first time, we have reported that mimivirus and moumouvirus induce superinfection inhibition in amoebas. In contrast, megaviruses do not exhibit this ability, allowing continuous entry of exogenous virions into infected amoebas. Our investigation shows that mimivirus and moumouvirus inhibit amoebic phagocytosis, causing significant changes in host cell morphology and activity. Megavirus-infected amoebas, however, continue incorporating newly formed viruses, affecting viral progeny. This research enhances our understanding of superinfection inhibition in these viruses, highlighting their differences in host interactions.

ABSTRACT

OBJECTIVE: Socioeconomic status and race have been found to influence patient outcomes for various cancer subtypes. In particular, minority and economically vulnerable patients present with more advanced disease and experience decreased survival compared to others. The aim of this study was to analyze the association between demographic or socioeconomic variables and rates of postsurgical follow-up after pituitary neuroendocrine tumor (PitNET) resection. METHODS: A retrospective review was completed for patients with PitNETs who underwent surgery between 2018 and 2021. Patient demographics and information related to postoperative appointments and magnetic resonance imagings were obtained. Social vulnerability index (SVI) scores were recorded from the Centers for Disease Control based on nationwide census tracts. RESULTS: One hundred and sixteen patients were included in the analysis (57 males). In this cohort, 50% were Black, 34% Hispanic, 9% White, and 1% Asian. The mean overall SVI score was 0.81 ± 0.23. The mean number of canceled appointments was significantly higher in the moderate-high/high SVI group (P = 0.034). Additionally, 30% of patients with moderate-high/high SVI had ≥2 canceled follow-up visits compared to 0% among patients with low/low-moderate SVI (P = 0.035). On average, White patients were less likely than non-White patients to have at least one canceled follow-up appointment (P = 0.048). CONCLUSIONS: Black patients and those with high social vulnerability have decreased rates of follow-up after PitNET resection. Follow-up delays can lead to failed identification of tumor recurrence, potentially resulting in more advanced disease by the time medical care is reinitiated and increasing rates of patient morbidity and mortality. As a result, further work is needed to address and bridge these care gaps.

ABSTRACT

Background: The Latarjet procedure was developed for the treatment of anterior shoulder instability in young, high-demand patients with attritional glenoid bone loss, whose risk of redislocation following primary dislocation may exceed 90%. Coracoid graft osteolysis and prominent screws are commonly observed in late computed tomography (CT) scans of patients who re-present following the procedure, but the clinical relevance of osteolysis in the overall Latarjet cohort is undetermined. We aimed to evaluate clinical and radiological outcomes in patients who underwent the Latarjet procedure, and to determine if severe coracoid graft osteolysis compromised clinical outcomes. Methods: This was a retrospective analysis of patients who underwent the open Latarjet procedure. Patients were invited via an e-questionnaire that contained a Western Ontario Shoulder Instability Index (WOSI), and queried about redislocation and reoperation since index surgery. Preoperative glenoid bone loss was calculated on CT using the best-fit circle method. Osteolysis was graded (0, screw head buried in graft; 1, screw head exposed; 2, threads exposed; 3, complete resorption/severe osteolysis) at the level of the proximal and distal screws respectively, on axial CT scans performed ≥ 12 months postoperatively. Results: Between 2011 and 2022, a single surgeon performed 442 Latarjet procedures. One hundred fifty eight patients responded to the questionnaire at median (interquartile range [IQR]) 44 (27-70) months postoperatively, among whom the median (IQR) WOSI score was 352 (142-666) points (0 = best, 2100 = worst). Recurrent anterior instability occurred in 3/158 (2%) patients. One patient required reoperation for this indication. Among patients who had CT scans ≥ 12 months postoperatively (median [IQR] 40 [29-69] months), 1 patient developed severe osteolysis around both screws (WOSI = 90), 17/62 (27%) patients developed severe osteolysis around 1 screw, all of which were proximal (median [IQR] WOSI = 235 [135-644]), and 44/62 (71%) patients did not develop severe osteolysis around either screw (median [IQR] WOSI = 487 [177-815]). There were no statistically significant differences in WOSI scores between groups based on the presence of severe osteolysis. Conclusion: The Latarjet is reliable procedure that has a low rate of redislocation and reoperation. Severe coracoid graft osteolysis occurs with time, and always affects the proximal graft first. The presence of severe osteolysis did not compromise clinical outcomes.

ABSTRACT

Photocrosslinking hydrogels are promising for tissue engineering and regenerative medicine, but challenges in reaction monitoring often leave their optimization subject to trial and error. The stability of crosslinked gels under fluid flow, as in the case of a microfluidic device, is particularly challenging to predict, both because of obstacles inherent to solid-state macromolecular analysis that prevent accurate chemical monitoring, and because stability is dependent on size of the patterned features. To solve both problems, we obtained 1H NMR spectra of cured hydrogels which were enzymatically degraded. This allowed us to take advantage of the high-resolution that solution NMR provides. This unique approach enabled the measurement of degree of crosslinking (DoC) and prediction of material stability under physiological fluid flow. We showed that NMR spectra of enzyme-digested gels successfully reported on DoC as a function of light exposure and wavelength within two classes of photocrosslinkable hydrogels: methacryloyl-modified gelatin and a composite of thiol-modified gelatin and norbornene-terminated polyethylene glycol. This approach revealed that a threshold DoC was required for patterned features in each material to become stable, and that smaller features required a higher DoC for stability. Finally, we demonstrated that DoC was predictive of the stability of architecturally complex features when photopatterning, underscoring the value of monitoring DoC when using light-reactive gels. We anticipate that the ability to quantify chemical crosslinks will accelerate the design of advanced hydrogel materials for structurally demanding applications such as photopatterning and bioprinting.

ABSTRACT

Retroclival hematomas are a rare entity, presenting anteriorly to the brainstem in the epidural, subdural, or subarachnoid space. Although those that develop in the epidural space often arise from trauma, subdural retroclival hematomas frequently occur spontaneously in the setting of coagulopathy, aneurysm rupture, or pituitary apoplexy, with many cases having an unknown etiology.1-4 Although most are treated with conservative management, surgical intervention is preferred for those presenting with evidence of brainstem compression, hydrocephalus, worsening neurological deficits, and clinical deterioration.5 In this report, we present the case of a 75-year-old woman with a medical history of mitral regurgitation, nonischemic cardiomyopathy, and atrial fibrillation on warfarin presenting with 4 days of temporoparietal headaches and double vision. On examination, the patient demonstrated right abducens and hypoglossal nerve palsies. Computed tomography revealed a subdural hemorrhage within the retroclival cistern, extending into the dorsal inferior aspect of the C2 vertebral body, resulting in posterior displacement of the pons, medulla, and proximal cervical spinal cord. Spinal and cerebral angiograms did not show evidence of any vascular malformation. An endoscopic transclival approach was selected for hematoma evacuation. Key surgical steps included harvesting of nasoseptal flap, endoscopic transnasal approach to the sellar/subsellar space, transclival drilling, retroclival hematoma evacuation, and clival reconstruction. The patient tolerated the procedure well and was discharged 15 days postoperatively with resolution of prior cranial nerve deficits. Postoperative computed tomography imaging revealed complete retroclival hematoma evacuation. At her 3-month follow-up, the patient remained neurologically intact with imaging confirming no residual subdural hematoma. Institutional Review Board approval was obtained for this submission (2018-9379). Patient consent was not obtained as personal identifying information was kept confidential, following guidelines set forth by Institutional Review Board requirements.

ABSTRACT

Enhanced rock weathering (EW) is an emerging atmospheric carbon dioxide removal (CDR) strategy being scaled up by the commercial sector. Here, we combine multiomics analyses of belowground microbiomes, laboratory-based dissolution studies, and incubation investigations of soils from field EW trials to build the case for manipulating iron chelators in soil to increase EW efficiency and lower costs. Microbial siderophores are high-affinity, highly selective iron (Fe) chelators that enhance the uptake of Fe from soil minerals into cells. Applying RNA-seq metatranscriptomics and shotgun metagenomics to soils and basalt grains from EW field trials revealed that microbial communities on basalt grains significantly upregulate siderophore biosynthesis gene expression relative to microbiomes of the surrounding soil. Separate in vitro laboratory incubation studies showed that micromolar solutions of siderophores and high-affinity synthetic chelator (ethylenediamine-N,N'-bis-2-hydroxyphenylacetic acid, EDDHA) accelerate EW to increase CDR rates. Building on these findings, we develop a potential biotechnology pathway for accelerating EW using the synthetic Fe-chelator EDDHA that is commonly used in agronomy to alleviate the Fe deficiency in high pH soils. Incubation of EW field trial soils with potassium-EDDHA solutions increased potential CDR rates by up to 2.5-fold by promoting the abiotic dissolution of basalt and upregulating microbial siderophore production to further accelerate weathering reactions. Moreover, EDDHA may alleviate potential Fe limitation of crops due to rising soil pH with EW over time. Initial cost-benefit analysis suggests potassium-EDDHA could lower EW-CDR costs by up to U.S. $77 t CO2 ha-1 to improve EW's competitiveness relative to other CDR strategies.

ABSTRACT

The discovery of mimivirus in 2003 prompted the search for novel giant viruses worldwide. Despite increasing interest, the diversity and distribution of giant viruses is barely known. Here, we present data from a 2012-2022 study aimed at prospecting for amoebal viruses in water, soil, mud, and sewage samples across Brazilian biomes, using Acanthamoeba castellanii for isolation. A total of 881 aliquots from 187 samples covering terrestrial and marine Brazilian biomes were processed. Electron microscopy and PCR were used to identify the obtained isolates. Sixty-seven amoebal viruses were isolated, including mimiviruses, marseilleviruses, pandoraviruses, cedratviruses, and yaraviruses. Viruses were isolated from all tested sample types and almost all biomes. In comparison to other similar studies, our work isolated a substantial number of Marseillevirus and cedratvirus representatives. Taken together, our results used a combination of isolation techniques with microscopy, PCR, and sequencing and put highlight on richness of giant virus present in different terrestrial and marine Brazilian biomes.

ABSTRACT

The definitive demonstration of protein localization on primary cilia has been a challenge for cilia biologists. Primary cilia are solitary thread-like projections that have a specialized protein composition, but as the ciliary structure overlays the cell membrane and other cell parts, the identity of ciliary proteins are difficult to ascertain by conventional imaging approaches like immunofluorescence microscopy. Surface scanning electron microscopy combined with immunolabeling (immuno-SEM) bypasses some of these indeterminacies by unambiguously showing protein expression in the context of the three-dimensional ultrastructure of the cilium. Here, we apply immuno-SEM to specifically identify proteins on the primary cilia of mouse and human pancreatic islets, including post-translationally modified tubulin, intraflagellar transport (IFT)88, the small GTPase Arl13b, as well as subunits of axonemal dynein. Key parameters in sample preparation, immunolabeling and imaging acquisition are discussed to facilitate similar studies by others in the cilia research community.

ABSTRACT

Introduction Prolactinomas are a common intracranial neoplasm and constitute most pituitary tumors. Although patients can present with variable hormone dysregulation and symptom severity, the use of dopamine agonists remains a first-line treatment. While bromocriptine has been found to increase tumor fibrosis, the effect of cabergoline on collagen deposition has been disputed. The aim of this article is to understand the influence of cabergoline on tumor fibrosis prior to resection. Case Presentations Four male patients who underwent prolactinoma resection were included in this report. The average age was 39.8 years (range: 26-52 years). Pre-treatment prolactin levels ranged from 957.8 to 16,487.4 ng/mL. Three patients received cabergoline for at least 1 month prior to surgery (treatment range: 1-6 months). One patient had surgery without prior cabergoline use. Pathology reports confirmed each tumor to be of lactotroph origin. For each sample, Masson's trichrome staining was performed and the percentage of sample fibrosis was quantified using an artificial intelligence imaging software. Among those who received preoperative cabergoline, the extent of tumor fibrosis was in the range of 50 to 70%. In contrast, specimen fibrosis was approximately 15% without cabergoline use. Conclusion This report demonstrates that a short duration of preoperative cabergoline can cause significant prolactinoma fibrosis. Understanding the effect of cabergoline on tumor consistency prior to surgery is essential as increased fibrosis can lead to more difficult tumor removal, reduce the extent of resection, and increase surgical complications. Considering these effects, further studies regarding the use of surgery prior to cabergoline for prolactinoma management are warranted.

ABSTRACT

Background: Neurosurgeons face particularly high rates of litigation compared to physicians in other fields. Malpractice claims are commonly seen after mismanagement of life-threatening medical emergencies, such as epidural haematomas. Due to the lack of legal analysis pertaining to this condition, the aim of this study is to identify risk factors associated with litigation in cases relating to the diagnosis and treatment of epidural haematomas. Materials and methods: Westlaw Edge, an online database, was used to analyze malpractice cases related to epidural haematomas between 1986 and 2022. Information regarding plaintiff demographics, defendant specialty, reason for litigation, trial outcomes, and payouts for verdicts and settlements were recorded. Comparative analysis between cases that returned a jury verdict in favour of the plaintiff versus defendant was completed. Results: A total of 101 cases were included in the analysis. Failure to diagnose was the most common reason for litigation (n = 64, 63.4%), followed by negligent care resulting in an epidural haematoma (n = 44, 43.6%). Spine surgery (n = 29, 28.7%), trauma (n = 28, 27.7%), and epidural injection/catheter/electrode placement (n = 21, 20.8%) were the primary causes of haematomas. Neurosurgeons (n = 18, 17.8%) and anesthesiologists (n = 17, 16.8%) were the two most common physician specialties cited as defendants. Most cases resulted in a jury verdict in favour of the defense (n = 54, 53.5%). For cases ending in plaintiff verdicts, the average payout was $3 621 590.45, while the average payment for settlements was $2 432 272.73. Conclusion: Failure to diagnose epidural haematomas is the most common reason for malpractice litigation, with neurosurgeons and anesthesiologists being the most common physician specialties to be named as defendants. More than half of all cases returned a jury verdict in favour of the defense and, on average, settlements proved to be more cost-effective than plaintiff verdicts.

ABSTRACT

High-grade gliomas (HGGs; WHO grade III or IV) are the most common and lethal brain malignancy. Patients of Hispanic ethnicity are diagnosed with HGGs earlier than non-Hispanic patients, but they exhibit improved HGG survival following diagnosis. Either environmental or biological factors could explain this survival benefit. We aimed to determine if post-diagnosis advantages would still be present in Hispanic patients with high social vulnerability, an environmental condition predisposing patients to poor oncologic outcomes. HGG outcomes were retrospectively assessed in a cohort of 22 Hispanic patients and 33 non-Hispanic patients treated for HGGs from 2015 to 2020 at a single institution that serves a highly vulnerable region. Compared to non-Hispanic patients, Hispanic patients demonstrated higher social vulnerability index scores (96.8 + 0.7 vs. 76.3 + 4.6; *** p = 0.0002) and a 14-month longer interval between diagnosis and recurrence (19.7 + 5.9 (n = 13) vs. 5.5 + 0.6 months (n = 19); ** p = 0.001). In only those patients with more aggressive IDH-1 wildtype tumors (glioblastoma), Hispanic ethnicity still related to a longer time before recurrence (15.8 + 5.9 months (n = 9); 5.5 + 0.6 months (n = 18); * p = 0.034), and in a multivariate analysis, Hispanic ethnicity predicted time-to-recurrence (* p = 0.027) independent of patient age, functional status, MGMT gene methylation, or treatments received. Therefore, environmental factors, specifically social vulnerability, did not obscure the post-diagnosis benefits associated with Hispanic ethnicity. In future experiments, basic studies should be prioritized which investigate the cellular or genetic mechanisms underlying this ethnicity effect on HGG progression in the hopes of improving care for these devastating malignancies.

ABSTRACT

Introduction Pituitary abscess is a rare disorder that represents a small fraction of all pituitary lesions. In this report, we present two additional cases with unique features to promote awareness and prompt surgical intervention. Case Presentations A 42-year-old male presented with headache, photophobia, subjective fever, dizziness, imbalance, nausea, and vomiting. A pituitary hormone panel confirmed hypothyroidism and suggested central hypogonadism and secondary adrenal insufficiency. Magnetic resonance imaging (MRI) showed a large sellar mass measuring 2.5 cm × 1.8 cm × 1.6 cm (CC × XT × AP). A 76-year-old woman presented with several months of headaches and unsteady gait in the setting of a known previously asymptomatic sellar lesion, measuring 1.8 cm × 1.2 cm × 1.5 cm (XT × CC × AP). Repeat MRI demonstrated possible hemorrhage within the lesion. In both cases, a preliminary diagnosis of pituitary macroadenoma was made, but transsphenoidal surgery revealed an encapsulated abscess; cultures obtained from the abscesses stained for gram-positive bacteria. Conclusion Pituitary abscess is a rare, potentially life-threatening disorder that may be easily mistaken for other sellar lesions. In this review, we contribute two additional cases of pituitary abscesses to increase awareness and emphasize the importance of proper diagnosis and management.

ABSTRACT

Of the targets for HIV-1 therapeutics, the capsid core is a relatively unexploited but alluring drug target due to its indispensable roles throughout virus replication. Because of this, we aimed to identify "clickable" covalent modifiers of the HIV-1 capsid protein (CA) for future functionalization. We screened a library of fluorosulfate compounds that can undergo sulfur(VI) fluoride exchange (SuFEx) reactions, and five compounds were identified as hits. These molecules were further characterized for antiviral effects. Several compounds impacted in vitro capsid assembly. One compound, BBS-103, covalently bound CA via a SuFEx reaction to Tyr145 and had antiviral activity in cell-based assays by perturbing virus production, but not uncoating. The covalent binding of compounds that target the HIV-1 capsid could aid in the future design of antiretroviral drugs or chemical probes that will help study aspects of HIV-1 replication.

ABSTRACT

Ensuring high standards of animal welfare is not only an ethical duty for zoos and aquariums, but it is also essential to achieve their conservation, education, and research goals. While for some species, animal welfare assessment frameworks are already in place, little has been done for marine animals under human care. Responding to this demand, the welfare committee of the European Association for Aquatic Mammals (EAAM) set up a group of experts on welfare science, cetacean biology, and zoo animal medicine across Europe. Their objective was to develop a comprehensive tool to evaluate the welfare of bottlenose dolphins (Tursiops truncatus), named Dolphin-WET. The tool encompasses 49 indicators that were either validated through peer review or management-based expertise. The first of its kind, the Dolphin-WET is a species-specific welfare assessment tool that provides a holistic approach to evaluating dolphin welfare. Inspired by Mellor's Five Domains Model and the Welfare Quality®, its hierarchical structure allows for detailed assessments from overall welfare down to specific indicators. Through combining 37 animal-based and 12 resource-based indicators that are evaluated based on a two- or three-level scoring, the protocol offers a detailed evaluation of individual dolphins. This approach allows for regular internal monitoring and targeted welfare management, enabling caretakers to address specific welfare concerns effectively.

ABSTRACT

The possibility that the Amazon forest system could soon reach a tipping point, inducing large-scale collapse, has raised global concern1-3. For 65 million years, Amazonian forests remained relatively resilient to climatic variability. Now, the region is increasingly exposed to unprecedented stress from warming temperatures, extreme droughts, deforestation and fires, even in central and remote parts of the system1. Long existing feedbacks between the forest and environmental conditions are being replaced by novel feedbacks that modify ecosystem resilience, increasing the risk of critical transition. Here we analyse existing evidence for five major drivers of water stress on Amazonian forests, as well as potential critical thresholds of those drivers that, if crossed, could trigger local, regional or even biome-wide forest collapse. By combining spatial information on various disturbances, we estimate that by 2050, 10% to 47% of Amazonian forests will be exposed to compounding disturbances that may trigger unexpected ecosystem transitions and potentially exacerbate regional climate change. Using examples of disturbed forests across the Amazon, we identify the three most plausible ecosystem trajectories, involving different feedbacks and environmental conditions. We discuss how the inherent complexity of the Amazon adds uncertainty about future dynamics, but also reveals opportunities for action. Keeping the Amazon forest resilient in the Anthropocene will depend on a combination of local efforts to end deforestation and degradation and to expand restoration, with global efforts to stop greenhouse gas emissions.

ABSTRACT

Many physicians, particularly neurosurgeons, face malpractice claims during their career. The aim of this paper is to identify which factors increase the risk of litigation and influence legal outcomes relating to cerebrospinal fluid shunt management. Westlaw, an online legal database, was used to identify all medico-legal cases pertaining to cerebrospinal fluid shunts. Information regarding plaintiff demographics, defendant specialties, reasons for litigation, and trial outcomes were analysed. Thirty-six cases met criteria for inclusion. Most cases returned a defence verdict (44.4%), with delayed treatment or failure to appropriately treat patients with shunts the most common reason for litigation (66.7%). The average plaintiff verdict payout was $4,888,136.75 and average settlement $1,362,307.69. Delay or failure to treat resulted in the largest average payouts for plaintiff verdicts and settlements ($5,329,299.14 and $1,531,500.00, respectively).

ABSTRACT

OBJECTIVES: Effective health communication can increase intent to vaccinate. We compared 8 messages that may influence parents' intent to vaccinate their children against COVID-19. METHODS: In a cross-sectional survey of adults in the United States administered online in August 2021, 1837 parents and legal guardians were exposed to 8 messages (individual choice, gain/practical benefits, nonexpert, health care provider recommendation, altruism/community good, safety/effectiveness, safety, and effectiveness) to determine message reception and influence on intent to vaccinate their children. Parents responded to 10 questions using a Likert scale. We computed odds ratios (ORs) for each message, with an OR >1.0 indicating greater observed odds of participant agreement with the follow-up statement as compared with a reference message. We compared outcomes individually across messages with ordinal logistic regression fit using generalized estimating equations. RESULTS: The individual choice message had the highest odds of agreement for understanding intent (OR = 2.10; 95% CI, 1.94-2.27), followed by the health care provider recommendation message (OR = 1.58; 95% CI, 1.46-1.71). The individual choice message had the highest odds of memorability, relatability, and trustworthiness. The altruism/community good message was at or near second best. The altruism/community good message had the highest or near-highest odds of increasing parents' intent to vaccinate their children, asking friends and family for their thoughts, and searching for additional information. The message that most motivated parents to vaccinate their children depended on parental intent to vaccinate prior to being exposed to the tested messages. CONCLUSIONS: Messages with themes of individual choice, health care provider recommendation, and altruism/community good may be used in future message campaigns. Further research is needed to refine message concepts related to altruism/community good.

ABSTRACT

OBJECTIVES: We compared characteristics and outcomes of individuals who in the cerebrospinal fluid (CSF) were positive for herpes simplex virus (HSV) or varicella-zoster virus (VZV)-intrathecal antibody index test ([AI]-positive) vs. individuals who were PCR-positive for HSV type 1 (HSV1), type 2 (HSV2), and for VZV. METHODS: Nationwide cohort study of all Danish residents with positive CSF-AI or -PCR for HSV or VZV (1995-2021). We calculated short- and long-term risks as age-, sex-, and comorbidity-adjusted odds ratios (aOR), adjusted hazard ratios (aHR), and absolute risk differences with 95% CIs. RESULTS: Compared with individuals with positive PCR for HSV1 (n = 321), HSV2 (n = 497), and VZV (n = 1054), individuals with a positive AI for HSV (n = 177) and VZV (n = 219) had CSF pleocytosis less frequently (leucocyte count >10/µL: HSV-AI: 39%, VZV-AI: 52%, HSV1-PCR: 81%, HSV2-PCR: 92%, VZV-PCR: 83%), and were less frequently diagnosed with central nervous system infection ([aOR {95%CI}]: HSV-AI vs. HSV1-PCR: [0.1 {0.1, 0.2}], HSV-AI vs. HSV2-PCR: [0.1 {0.0, 0.1}], VZV-AI vs. VZV-PCR: [0.2 {0.2, 0.3}]). Individuals with a positive HSV-AI or VZV-AI had increased risk of demyelinating disease ([aOR {95%CI}; aHR {95%CI}]: HSV-AI vs. HSV1-PCR: [4.6 {0.9, 24.5}; aHR not applicable], HSV-AI vs. HSV2-PCR: [10.4 {2.3, 45.9}; 12.4 {2.3, 66.0}], VZV-AI vs. VZV-PCR: [aOR not applicable; 10.3 {1.8, 58.8}]). Disability pension was less frequent among HSV-AI than HSV1-PCR cohort members (5-year risk difference: -23.6%, 95%CI: -35.2, -11.8), and more frequent among VZV-AI than VZV-PCR cohort members (5-year risk difference: 16.8%, 95%CI: 5.0, 28.7). DISCUSSION: AI-positive individuals differ from PCR-positive individuals in several aspects. AI appears unspecific for current central nervous system infections.
