ABSTRACT

PURPOSE: The purpose of this systematic review was to explore and identify the factors that influence the accuracy of intraoral scanning in implant dentistry, with a specific focus on scan bodies (ISBs).

METHODS: Following the PRISMA 2020 guidelines, this study conducted a thorough electronic search across MedLine, PubMed, and Scopus to identify relevant studies. Articles were screened based on titles, abstracts, and full texts for relevance. The Robins I tool assessed the risk of bias in various study types. Data extraction occurred based on predetermined parameters for studying specimens and assessing outcomes.

RESULTS: 16 studies met the specified criteria and were consequently included in the systematic review. Due to variations in variables and methods across the selected studies, statistical comparison of results was not feasible. Therefore, a descriptive review approach was chosen, acknowledging the substantial heterogeneity in the reviewed literature.

CONCLUSIONS: The precision of virtual scan results is contingent upon diverse characteristics of ISBs and implants. These factors encompass their placement within the dental arch, structural design, shape, material composition, color, and the manufacturing system, all of which contribute to scan accuracy. Additionally, considerations such as the intraoral scanner (IOS) type, scanning technique, use of scan aids, inter-implant distance, scan span, and the number of implants warrant evaluation. In the context of capturing implant positions, intraoral scanning with ISBs demonstrates comparable accuracy to traditional impression methods, particularly in single and short-span scenarios. However, the existing data lacks sufficient information on in vivo applications to formulate clinical recommendations.

ABSTRACT

PURPOSE: This study is centered on the critical role of anterior fibromuscular stroma (AFS) preservation in prostate enucleation, an emerging strategy aimed at minimizing postoperative urinary incontinence-a common concern in benign prostatic hyperplasia (BPH) surgeries. By focusing on postoperative voiding volumes (VV), our research investigates the efficacy of AFS preservation. This approach, distinct in its methodology, is hypothesized to improve urinary function post-surgery, thereby offering a potentially significant advancement in BPH surgical treatments.

MATERIALS AND METHODS: A retrospective analysis was conducted, comparing patients who underwent prostate enucleation in 2017 without intentional AFS preservation to those in 2019 with this technique. We examined variables including age, BMI, diabetes, hypertension, and preoperative VV to assess their effect on post-catheter removal VV. The study’s methodology includes a thorough review of the primary statistical analysis methods employed.

RESULTS: Our analysis indicates that while the 2017 and 2019 cohorts were similar in most preoperative parameters, the 2019 group that underwent AFS-preserved surgery showed a significant improvement in postoperative VVs. This was less pronounced in the patient group aged over 70, underscoring the importance of this demographic in our study.

CONCLUSIONS: The study concludes that intentional preservation of AFS during prostate enucleation positively impacts early postoperative VVs, with limited improvement in older patients. These findings highlight the potential of AFS preservation not only in enhancing urinary outcomes post-surgery but also in shaping future BPH surgical procedures and research directions.

ABSTRACT

Following the U.S. military’s departure from Afghanistan, a significant number of Afghan refugees have resettled in the United States, presenting complex mental health challenges exacerbated by extensive traumatic exposure. This demographic is particularly affected by collective trauma due to war, genocide, and the loss of homeland. However, detailed investigations into the correlations between collective trauma and mental health outcomes among Afghan refugees are limited. This study sought to explore the relationship between collective trauma and mental health outcomes within the Afghan refugee population in the United States, paying particular attention to the influence of sociodemographic factors. Identifying subgroups at greater risk allows for the development of more targeted mental health interventions. The study surveyed 173 Afghan refugees employing snowball sampling, utilizing a cross-sectional design. Data collection was facilitated through online and in-person surveys in English, Dari, and Pashto. Key measures included the Harvard Trauma Questionnaire for individual trauma experiences, the Historical Loss Scale for collective trauma, the Historical Loss Associated Symptoms Scale for collective trauma symptoms, the Afghan Symptom Checklist-22 for mental health symptoms, and the Post-Migration Living Difficulties Scale for post-migration stressors. Statistical analyses involved Pearson’s correlation for variable associations, with nonparametric Mann-Whitney U and Kruskal-Wallis tests conducted to assess sociodemographic impacts due to data’s non-normal distribution. The analysis revealed significant variations in collective trauma and mental health outcomes across subgroups. Afghan women, minoritized ethnic groups, those who experienced extended displacement, and refugees with uncertain visa statuses reported higher collective trauma levels and worse mental health outcomes. Statistical significance was noted in the correlations between collective trauma and mental health symptoms (r = .53, p < .01) and between post-migration difficulties and mental health (r = .33, p < .01). The disparities in mental health outcomes based on sociodemographic characteristics were significant, with nonparametric tests showing clear distinctions across different groups (Kruskal-Wallis H = 14.76, p < .05 for trauma experience by visa status). This study emphasizes the critical need for mental health interventions that account for the complex experiences of collective trauma among Afghan refugees, especially among identified subgroups. Tailoring mental health services to address the specific needs highlighted through disaggregated data can enhance support for Afghan refugees in the United States. This research contributes to a deeper understanding of the relationship between collective trauma and refugee mental health, advocating for nuanced care strategies in resettlement environments.

ABSTRACT

PURPOSES: Polyglycolic acid (PGA) sheets, fibrin glue, and staple line reinforcement are frequently used to prevent air leakage during lung resection. However, the optimal staple-line reinforcement method remains unclear.

METHODS: Cranial lung lobes of pigs were used to evaluate different staple line reinforcement methods (n = 6). Ventilator-assisted manometry was used to measure the maximum resistance pressure at the time of rupture of the lung tissue after stapling.

RESULTS: The mean maximum resistance pressures at the time of lung tissue rupture after using the stapler alone, stapler with PGA sheet and fibrin glue, and stapler with reinforcement were 38.0 cmH₂O, 51.3 cmH₂O, and 62.7 cmH₂O, respectively. A significant increase in the maximum resistance pressure was observed with stapler reinforcement (P < 0.001), while the differences between the other groups were not statistically significant (P = 0.055, P = 0.111). A histological assessment revealed disruption of alveolar structures near the needle-stitching site in the stapler alone, and in the stapler with PGA sheet and fibrin glue groups. Pleural rupture near the staple line was observed in the stapler with reinforcement group.

CONCLUSIONS: The maximum resistance pressure before air leakage was significantly higher when using a stapler with reinforcement than when using a stapler alone.

ABSTRACT

PURPOSE: To evaluate the effect of adjuvant Mitomycin C (MMC) use on the anatomical and functional success of vitreoretinal surgery (VRS) in severe diabetic tractional retinal detachment (dTRD) patients.

METHODS: A retrospective analysis of consecutive patients undergoing VRS due to severe dTRD was conducted. Patients were categorized into those who received 20 µg/0.1 mL MMC via MMC sandwich method (Group 1) and those who did not (Group 2). Demographics, surgical characteristics, visual outcomes, and complications that may related to MMC were analyzed.

RESULTS: A total of 25 eyes were included, 13 in Group 1 and 12 in Group 2. No statistical difference was observed in baseline characteristics between the groups. The mean best-corrected visual acuity was 1.90 ± 0.43 logMAR and 1.93 ± 0.41 logMAR preoperatively and 1.60 ± 0.78 logMAR and 1.56 ± 0.78 logMAR postoperatively in Groups 1 and 2, respectively (p = 0.154). The postoperative mean intraocular pressure was 16.23 ± 2.55 mmHg and 13.08 ± 4.94 mmHg in Groups 1 and 2, respectively (p = 0.225). The rate of re-surgery was significantly lower in Group 1 (0% vs. 41.7% in Group 2, p = 0.015). Retina was attached in all patients at the last visit. No MMC-related complication was recorded.

CONCLUSION: Intraoperative adjuvant MMC application for severe dTRD significantly reduces re-surgery rates with good anatomical and functional outcomes safely.

ABSTRACT

Most water-borne disease models ignore the advection of water flows in order to simplify the mathematical analysis and numerical computation. However, advection can play an important role in determining the disease transmission dynamics. In this paper, we investigate the long-term dynamics of a periodic reaction-advection-diffusion schistosomiasis model and explore the joint impact of advection, seasonality and spatial heterogeneity on the transmission of the disease. We derive the basic reproduction number $R_0$ and show that the disease-free periodic solution is globally attractive when $R_0<1$ whereas there is a positive endemic periodic solution and the system is uniformly persistent in a special case when $R_0>1$ . Moreover, we find that $R_0$ is a decreasing function of the advection coefficients which offers insights into why schistosomiasis is more serious in regions with slow water flows.

ABSTRACT

BACKGROUND AND OBJECTIVE: Psychological stress has been identified in some observational studies as a potential factor that may modify and affect periodontal diseases, but there are no similar data for peri-implantitis. The aim of this study was to determine the relationship between interleukin (IL)-1β, IL-6, IL-10, interferon (IFN)α inflammatory cytokines and the psychological stress-related markers, glucocorticoid receptor-α (GRα), and salivary α-amylase (sAA) gene expression levels in saliva samples obtained from healthy implants and peri-implantitis patients.

MATERIALS AND METHODS: The study included a total of 50 systemically healthy subjects. Peri-implant clinical parameters were recorded and psychological stress level was evaluated with the hospital anxiety and depression scale (HAD) and state-trait anxiety inventory (STAI) questionnaire forms. Following the evaluations, the patients were divided into 4 groups according their stress and clinical status (Ia, Ib, IIa, IIb). IL-1β, IL-6, IL-10, IFNα, GRα, sAA gene expression levels in the saliva samples were quantified by quantitative polymerase chain reaction (qPCR).

RESULTS: In the group of peri-implantitis who had a high score in stress level assessment scales, significantly higher IL-1β, IL-6, sAA expression levels were observed (p < 0.001). The IL-10 gene expression levels were lower in the groups with a high score in the stress level assessment scales (p < 0.001). GRα gene was expressed at lower levels in the group of peri-implantitis who had a high score in stress level assessment scales but the difference was not statistically significant (p = 0.065).

CONCLUSION: The study findings suggest that psychological stress may increase the inflammation associated with peri-implantitis by affecting cytokine expression levels.

CLINICAL RELEVANCE: To prevent peri-implantitis or reduce its prevalence, it could be beneficial to evaluate stress levels and identify individuals experiencing stress.

ABSTRACT

BACKGROUND: Provoked anger is associated with an increased risk of cardiovascular disease events. The underlying mechanism linking provoked anger as well as other core negative emotions including anxiety and sadness to cardiovascular disease remain unknown. The study objective was to examine the acute effects of provoked anger, and secondarily, anxiety and sadness on endothelial cell health.

METHODS AND RESULTS: Apparently healthy adult participants (n=280) were randomized to an 8-minute anger recall task, a depressed mood recall task, an anxiety recall task, or an emotionally neutral condition. Pre-/post-assessments of endothelial health including endothelium-dependent vasodilation (reactive hyperemia index), circulating endothelial cell-derived microparticles (CD62E+, CD31+/CD42-, and CD31+/Annexin V+) and circulating bone marrow-derived endothelial progenitor cells (CD34+/CD133+/kinase insert domain receptor+ endothelial progenitor cells and CD34+/kinase insert domain receptor+ endothelial progenitor cells) were measured. There was a group×time interaction for the anger versus neutral condition on the change in reactive hyperemia index score from baseline to 40 minutes (P=0.007) with a mean±SD change in reactive hyperemia index score of 0.20±0.67 and 0.50±0.60 in the anger and neutral conditions, respectively. For the change in reactive hyperemia index score, the anxiety versus neutral condition group by time interaction approached but did not reach statistical significance (P=0.054), and the sadness versus neutral condition group by time interaction was not statistically significant (P=0.160). There were no consistent statistically significant group×time interactions for the anger, anxiety, and sadness versus neutral condition on endothelial cell-derived microparticles and endothelial progenitor cells from baseline to 40 minutes.

CONCLUSIONS: In this randomized controlled experimental study, a brief provocation of anger adversely affected endothelial cell health by impairing endothelium-dependent vasodilation.

ABSTRACT

Small headwater streams can mobilize large amounts of terrestrially derived dissolved organic matter (DOM). While the molecular composition of DOM has important controls on biogeochemical cycles and carbon cycling, how stationary landscape metrics affect DOM composition is poorly understood, particularly in relation to non-stationary effects from hydrological changes across seasons. Here, we apply a combination of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) and absorbance spectroscopy to characterize stream DOM from 13 diverse watersheds across the central Canadian boreal forests and statistically relate DOM compositional characteristics to landscape topography and hydrological metrics. We found that watershed runoff across different surface physiographies produced DOM with distinctly different chemical compositions related to runoff pH. Specifically, streams in sandy soil watersheds contained more abundant aromatic, nitrogenated and sulfurized fractions of DOM, likely due to a combination of lower soil capacity to absorb DOM than other soil types and high conifer forest coverage that generated acidic litterfall in more sandy watersheds. In contrast, streams with more neutral pH in watersheds with shallow soils had DOM resembling low oxidized phenolic molecules mainly due to increased brush/alder and deciduous vegetation coverage in relatively steeper watersheds. However, as precipitation and flows increased in the fall, the overall water chemistry of streams became more similar as runoff pH increased, the overall chemical diversity of DOM in streams decreased, and stream DOM resembled fresher, lower molecular weight lignin material likely originating from freshly produced leaf litter. Together, our findings show that during hydrologically disconnected periods, pH and landscape characteristics have important controls on the mobilization of aromatic DOM but that many landscape-specific characteristics in the Canadian boreal forest are less influential on DOM processing during wetter conditions where chemically similar, plant-derived DOM signatures are preferentially mobilized. These findings collectively help predict the composition of DOM across diverse watersheds in the Canadian boreal to inform microbial and contaminant biogeochemical processes in downstream ecosystems.
