alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

This study evaluates facial and tongue function in patients undergoing side-to-end hypoglossal-to-facial transfer (HFT) with additional techniques.

Methods

Thirty-seven patients underwent a side-to-end HFT. Twelve had additional cross-face grafts, and 9 had an additional masseter-to-facial transfer. Facial was assessed with House–Brackmann (HB), Sunnybrook Facial Grading Scale (SFGS), and eFACE. Martins scale and the Oral-Pharyngeal Disability Index (OPDI) were used to assess tongue function.

Results

Ninety-four percent of cases reached HB grades III–IV. Mean total SFGS score improved from 16 ± 15 to 59 ± 11, while total eFACE score from 52 ± 13 to 80 ± 5. Dual nerve transfers were a predictor for a better eFACE total score p = 0.034, β = 2.350 [95% CI, 0.184–4.516]), as well as for a higher SFGS total score (p = 0.036, β = 5.412 [95% CI, 0.375–10.449]). All patients had Martin's grade I. Mean postoperative OPDI scores were 84 ± 17 (local physical), 69 ± 16 (simple and sensory motor components), 82 ± 14 (complex functions), and 73 ± 22 (psychosocial).

Conclusions

The side-to-end HFT offers predictable facial function outcome and preserves tongue function in nearly all cases. Dual nerve transfers appear to improve the final outcome.

Bad, mad, or glad? Exploring the relationship between leaders’ appraisals or attributions of their use of abusive supervision and emotional reactions

alexandrossfakianakis shared this article with you from Inoreader

Abstract

A large body of research has documented the ill effects of abusive supervision. However, this begs the question of why these behaviors continue to occur. To address this question, we contend that scholars need to understand how leaders – the perpetrators of these actions – make sense of abusive supervision. Specifically, drawing upon theories of appraisal and attribution, this paper examines leaders' cognitions of who is accountable for incidents of abusive supervision (i.e., the leader or the subordinate) and their future expectations (i.e., are individuals likely to engage in the same behaviors subsequently or capable of change) and how these appraisals interact to shape emotional reactions. We conducted three complementary studies: a pilot study to identify relevant emotions, an event-based experience sampling study (Study 1), and a retrospective recall study (Study 2). Accountability appraisals were associated with emotions, such that appraisals that oneself (vs. one's subordinate) was more responsible for the incident were linked to higher levels of guilt and shame. Although growth mindset moderated associations between accountability appraisals and emotions, it did so for different emotions across the two studies (i.e., hostility in Study 1 and shame in Study 2). Implications for theory and practice are discussed.

Longer length of stay, days between discharge/first readmission, and pulmonary involvement ≥50% increase prevalence of admissions in ICU in unplanned readmissions after COVID‐19 hospitalizations

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Hospital readmissions due to COVID-19 are one of the main concerns for the health system due to risks to the patient's life and increased use of health resources. Studies focusing on this issue are important to understand the risk factors and create strategies to avoid readmissions. We evaluated the readmission of patients with confirmed COVID-19 in a private hospital in southern Brazil, between March 2020 and 2021. Also, the characteristics and clinical outcomes of patients admitted to the intensive care unit (ICU) and nonadmitted were compared. Poisson regression models with prevalence ratio (PR) with 95% confidence intervals (95% CIs) were applied to confirm the association between variables and ICU admission. Of the 2084 hospitalized patients with COVID-19, 1806 were discharged alive. Among them, 106 were readmitted for unplanned reasons during one year. Early hospital readmission (≤30 days) occurred in 52.8% of the cases. The main reasons were respiratory, gastroe nterological, kidney, and cardiac disease. The median age was 73.0 years old and women correspond to 52.8%. The presence of at least one comorbidity was detected in 87.7% of patients. Hypertension, diabetes, cardiac, and lung disease were more frequent. The ICU admitted patients (n = 43; 40.5%) mostly had 4–5 comorbidities, pulmonary involvement ≥50%, length of stay (LOS), and days between discharge and first readmission. Longer LOS (PR: 3.46; 95% CI: 1.24–5.67), days between discharge/first readmission (PR: 2.21; 95% CI: 1.15–5.88), and pulmonary involvement (≥50%; PR: 1.59; 95% CI: 1.11–3.54) were independently associated with ICU admission. Longer LOS, longer days between discharge/first readmission, and pulmonary involvement (≥50%) were associated with ICU admission in readmitted patients. Readmissions evaluation is pivotal and may help in ensuring safe care transition and postdischarge follow-up.

Memory impairment and concentration problems in COVID‐19 survivors eight weeks after non‐ICU hospitalization: a retrospective cohort study

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Studies on the SARS-CoV-1 have shown long term effects on health, rehabilitation and quality of life in patients.

Objective

To evaluate effects on recovery and mental health in COVID-19 survivors

Methods

A single centre, retrospective cohort study in (non ICU admitted) adult patients with COVID-19 infection was conducted. Next to baseline characteristics during hospital admission, data on remaining symptoms and radiographic abnormalities were extracted at the 8-week follow-up at the outpatient clinic. The HADS (Hospital Anxiety and Depression Scale) was used to detect anxiety and depression.

Results

211 patients were included, median age 63 years, 61% male, with overweight (average BMI 28.6 kg/m2). At the outpatient clinic 13% of the patients were symptom free, whereas 25% reported more than three symptoms. Persisting physical symptoms were mainly fatigue 68%, dyspnea 56% and cough 26%. Most patients had norma lisation of chest X-ray (61.1%) and oxygen saturation (89.9%). Interestingly, 33% reported memory impairment and concentration problems 28%. 7.8% scored for anxiety and 7.1% for depression on the HADS. Correlations were found between the number of physical symptoms and scores on the HADS.

Conclusion

Only 13% had symptom free recovery after 8 weeks. Besides physical symptoms memory problems were frequently seen. The number of mental and physical symptoms were correlated.

Two conserved amino acids differentiate the biology of high‐risk and low‐risk HPV E5 proteins.

alexandrossfakianakis shared this article with you from Inoreader

Abstract

The high-risk alpha human papillomaviruses (HPVs) are responsible for 99% of cervical cancers. While the biological functions of the HPV E6 and E7 oncoproteins are well-characterized, the function of E5 has remained elusive. Here, we examined gene expression changes induced by E5 proteins from high-risk HPV-16 and low-risk HPV-6b in multiple pools of primary human keratinocytes. Surprisingly, microarray analysis revealed that over 700 genes were significantly regulated by HPV-6b E5, while only 25 genes were consistently and significantly regulated by HPV-16 E5 in three biological replicates. However, we observed that more than thousand genes were altered in individual sample compared to vector. The gene expression profile induced by 16E5 in primary genital keratinocytes was very different from what has been previously published using immortalized HaCaT cells. Genes altered by HPV-16 E5 were unaffected by HPV-6b E5. Our data demonstrate that E5 proteins from the high- and low-risk HPVs have different functions in the HPV-host cell. Interestingly, conversion of two amino acids in HPV-16 E5 to the low-risk HPV-6b sequence eliminated the induction of high-risk related cellular genes.

Examining the role of brooding, distress, and negative urgency in dysregulated behaviors: A cross‐sectional study in treatment‐seeking young people

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objective

Dysregulated behaviors including substance use, disordered eating, and nonsuicidal self-injury (NSSI) have significant negative implications for individuals and health systems. It is therefore paramount to understand factors influencing behavioral dysregulation, to inform prevention and treatment approaches. The literature suggests that distress and rumination (brooding) prompt individuals to engage in behavioral dysregulation for distraction (Emotional Cascade Model), although these concepts have limited investigation in clinical, treatment-seeking samples, particularly alongside negative urgency. This cross-sectional study sought to examine the relationships of brooding, distress, and negative urgency with behavioral dysregulation, as well as the moderating effect of negative urgency between brooding and behavioral dysregulation, in treatment-seeking young people.

Method

A total of 385 treatment-seeking young people completed cross-sectional, self-report measures of distress, rumination, negative urgency, and engagement in dysregulated behaviors (NSSI, alcohol use, drug use, binge eating, and purging) over the past 1−3 months.

Results

Structural equation modeling revealed that only negative urgency, and not brooding or distress, had a significant positive relationship with behavioral dysregulation. Negative urgency did not significantly moderate the relationship between brooding and behavioral dysregulation.

Conclusions

These findings reinforce the importance of considering negative urgency in the conceptualization, prevention, and treatment of behavioral dysregulation, and contribute to the knowledge of the relationship between brooding and various dysregulated behaviors within a treatment-seeking sample.

The moderating role of sexual minority status in the associations of the experience and tolerance of shame‐related emotions to suicide risk

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objective

This study examined the associations of the experience and tolerance of shame-related emotions to suicide risk, as well as the moderating role of sexual minority status.

Methods

Community adults (N = 360) were recruited via MTurk and completed self-report questionnaires. Hierarchical regression analyses examined the main and interactive associations of sexual minority status and shame-related variables to suicide risk.

Results

Results revealed significant positive associations between self-disgust and suicide risk for sexual minority and heterosexual participants, although the magnitude was greater for sexual minority participants. Additionally, tolerance of shame was significantly negatively related to suicide risk only among sexual minority participants. Finally, exploratory analyses examining the three-way interaction of self-disgust, shame tolerance, and sexual minority status revealed a significant negative association between shame tolerance and suicide risk only among sexual minority participants with high levels of self-disgust.

Conclusion

Results highlight the relevance of shame-related experiences to suicide risk among sexual minorities.

Predictors of posttraumatic stress symptom severity and meaning made in treatment‐seeking veterans

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objective

Combat-exposed veterans risk encountering events that disrupt beliefs. To facilitate reduced discrepancy between prior beliefs and current trauma appraisals, veterans may engage in a process of meaning-making. Meaning-making can lead to positive outcomes, such as integrating the traumatic event into one's life narrative or adapting global meaning (meaning made) or elicit distress. Given these potentially different outcomes, this study examined potential correlates of posttraumatic stress symptom (PTSS) severity and meaning made, including relationship attachment dimensions of anxiety and avoidance, and difficulties with emotion regulation, while controlling for combat exposure.

Method

Veterans receiving mental health services at a Veterans Affairs (VA) Medical Center and a VA community-based outpatient clinic (N = 130) completed measures through a paper-and-pencil survey. Almost all participants (92%) were male, with a mean age of 55.92 years.

Results

In terms of meaning made, lower levels of attachment anxiety and emotional clarity (an aspect of emotion regulation) predicted higher meaning made. In terms of PTSS severity, higher attachment avoidance, attachment anxiety, and difficulties engaging in goal-directed behavior (an aspect of emotion regulation) significantly predicted higher PTSS severity.

Conclusion

Aspects of both attachment style and emotion regulation difficulties affect meaning made and PTSS severity. These constructs may be especially relevant for clinicians working with veterans to help PTSS and support meaning made postcombat.

A Novel Spinal Cord Stimulation System with a Battery‐Free Micro Implantable Pulse Generator

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Spinal cord stimulation (SCS) is effective for the treatment of chronic intractable pain of the trunk and limbs. The mechanism of action may be based, at least in part, upon the gate control theory; however, new waveforms may suggest other mechanisms. Although benefits of the SCS technology generally outweigh the complications associated with SCS, some complications such as infection and skin erosion over the implant can result in device removal. Additional reasons for device removal, such as pocket pain and battery depletion, have driven technological innovations including battery-free implants and device miniaturization. The neurostimulation system described here was specifically designed to address complications commonly associated with implantable batteries and/or larger implantable devices. The benefits of the small size are further augmented by a minimally invasive implant procedure. Usability data show that patients found this novel neurostimulation system to be easy to use and comfortable to wear. What is more, clinical data demonstrate that the use of this system provides statistically significant reduction in pain scores with responder rates (defined as ≥ 50% reduction in pain) of 78% in the low back and 83% in the leg(s). Advances in miniaturization technology arose from the considerable shrinkage of the integrated circuit, with an increase in performance, according to Moore's law (1965). However, commensurate improvements in battery technology have not maintained a similar pace. This has prompted some manufacturers to place the battery outside, against the skin, thereby allowing a massive reduction in the implant volume, with the hopes of fewer device-related complications.

In Silico Finite Element Analysis of Implant‐Supported CAD‐CAM Resin Composite Crowns

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Purpose

The aim of this study was to evaluate the mechanical behavior of an implant-supported crown made using computer-aided design and computer aided manufacturing (CAD-CAM) resin composite (RC) blocks in the posterior region.

Material and methods

Four commercially available CAD-CAM RC blocks were used in this study: Cerasmart 300 (CS300; GC, Tokyo, Japan), Katana Avencia P Block (KAP; Kuraray Noritake Dental, Niigata, Japan); KZR HR3 Gamma Theta (HR3; Yamakin, Osaka, Japan), and Estelite P block (ESP; Tokuyama Dental, Tokyo, Japan). Katana Zirconia STML (ST; Kuraray Noritake Dental) was used as the control group. The elastic moduli of each material were determined by a three-point bending test. After the CAD models were designed, two different loading scenarios (oblique, vertical) were created. 3D finite element analysis was conducted with the prepared models.

Results

The elastic modulus of the material utilized for the implant restorations did not cause any change in the stresses transmitted to the implant or peripheral bone. An important difference was detected in the abutment–crown junction area. The minimum von Mises value at the abutment-crown interface was obtained in ST, which has the closest elastic modulus to the titanium abutment.

Conclusions

The 3D finite element model designed in this study was used to demonstrate that implant-supported crowns fabricated with four different CAD-CAM RCs showed no critical stress concentrations in the bone or implant under all loading conditions. These results suggest that CAD-CAM RC blocks could be used as an alternative material for implant-supported restorations in the posterior region in terms of stress distribution.

Feasibility of face mask spirometry during decannulation in head and neck surgery: prospective cohort study

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objectives

To analyze the relationship between spirometric parameters measured with a face mask versus a mouthpiece, as well as the feasibility of face mask spirometric evaluation in a head and neck surgery (HNS) decannulation context. Furthermore, we examine peak inspiratory flow (PIF) cut-off values before and after decannulation.

Design

Prospective cohort study.

Setting

Otolaryngology HNS Department of a University teaching hospital.

Participants

Twenty-four patients were selected. A maximal flow-volume loop was conducted before (with mouthpiece) and after (with mouthpiece and face mask) decannulation.

Main outcome measures

Recorded outcomes were forced vital capacity (FVC), forced expiratory volume in the first second, peak expiratory flow, PIF, forced expiratory flow at 50% of FVC and forced inspiratory flow at 50% of FVC. Spearman correlation coefficients between spirometric parameters measured with a face mask versus a mouthpiece were calculated. Wilcoxon test was used to check differences between mouthpiece and face mask values.

Results

Correlation between mouthpiece and face mask spirometric values was moderate to high (r = 0.46 to 0.95). All parameters measured by spirometry were significantly lower with a face mask than those obtained with a mouthpiece (p < 0.05). Before decannulation, the lowest PIF value (tested with mouthpiece) that allowed successful decannulation was 1 L/s. After decannulation, the lowest PIF value tested with mouthpiece and face mask for successful completion of the decannulation process were 0.77 and 0.56 L/s, respectively.

Conclusion

Face mask is a feasible option to perform a spirometry when face diseases hinder spirometric evaluation through a mouthpiece in an HNC surgery context.

Tooth as graft material: Histologic study

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

An effective regenerative protocol is key to reestablish and maintain the hard and soft tissue dimensions over time. The choice of the graft material and its properties also could have an impact on the results. To prevent alveolar ridge dimensional changes, since numerous graft materials have been suggested and in the past years, a growing interest in teeth material has been observed as a valuable alternative to synthetic biomaterials.

Aim

The aim of the study was to explore the histomorphometric outcomes of tooth derivative materials as used as bone substitute material in socket preservation procedure.

Methods

After alveolar socket preservation (ASP) procedures using autologous demineralized tooth as graft material prepared by means of an innovative device, was evaluated. A total of 101 histological samples, from 96 subjects, were analyzed by evaluating the total amount of bone (BV), residual tooth material (residual graft, TT), and vital bone (VB). The section from each sample was then split in nine subsections, resulting in 909 subsections, to allow statistical comparison between the different areas.

Results

It was not noticed a statistically significant difference between maxillary and mandibular sites, being the amount of VB in upper jaw sites 37.9 ± 21.9% and 38.0 ± 22.0% in lower jaw sites and the amount of TT was 7.7 ± 12.2% in maxilla and 7.0 ± 11.1% in mandibles. None of the other considered parameters, including defect type and section position, were statistically correlated to the results of the histomorphometric analysis.

Conclusions

ASP procedure using demineralized autologous tooth-derived biomaterial may be a predictable procedure to produce new vital bone potentially capable to support dental implant rehabilitation.
