Exploring grandiose narcissism among surgeons: a comparative analysis.

The concept of narcissism encompasses various personality traits, including cognitive, emotional and behavioural characteristics, which often lead to difficulties in maintaining a healthy self-esteem. This study examines the prevalence of narcissism traits (Admiration and Rivalry) in the surgical profession and their association with age, gender and professional experience. A total of 1390 participants (408 women, 982 men) took part in an online survey. The results show that female participants have significantly lower levels of rivalry than male colleagues. Additionally, age was found to be inversely correlated with both facets of narcissism, demonstrating that levels of narcissism decrease as age increases. Participants who are still in education tend to show higher levels of both facets. These results improve our understanding of personality traits in surgery and provide valuable insights for researchers and practitioners.

Evaluation of a Four-Week Online Resilience Training Program for Multiple Sclerosis Patients.

The diagnosis of a chronic disease, such as multiple sclerosis, has both psychological and physical effects. Living with the disease and its uncertain consequences requires a great deal of psychological resilience in order to employ more comprehensive coping strategies in stressful situations. This study investigated the effect of a four-week online self-directed resilience training program on the perception of psychological resilience among multiple sclerosis patients. A total of 94 MS patients were recruited for a randomised controlled trial. The experimental group underwent a 28-day online self-directed training program consisting of daily exercises aimed at strengthening a resilient mindset. Psychological resilience was measured through self-assessment immediately before, immediately after, and three months after the training. A repeated measures ANOVA revealed a statistically significant improvement in the perception of four factors related to stress: perceived worries, tension, joy, and demands. Two resilience coping strategies were measured, of which one, a resilient orientation, improved significantly in the short and long term. The study suggests that online self-directed resilience training might provide an easily accessible, low-cost option for patients with MS to improve their psychological resilience. This is a pilot study to assess the general applicability to people with MS. Future studies should examine the transferability of results in relation to disease stage and co-morbidities.

Comparison of Five Different Treatment Approaches of Mandibular Keratocystic Odontogenic Keratocyst (OKC): A Retrospective Recurrence Analysis of Clinical and Radiographic Parameters.

The odontogenic keratocyst (OKC) is a benign but locally aggressive growing lesion that infiltrates the bone and surrounding tissue. It is characterized by high rates of recurrence along with rapid growth. Different forms of partly successful treatment therapies are reported. The retrospective study at hand examined 114 patients with OKC treated over a period of 20 years. Data extracted includes gender, age, location, previous treatment for the lesion, surgery, outcome, recurrence rate and follow-up. 63.1% of the patients underwent cystectomy, 22.5% by cystectomy and carnoy solution, 7.2% by cystectomy, and curettage, 4.5% by cystostomy and 2.7% by partial resection. In this study, no significant differences could be observed regarding the surgical method. Most recurrences occurred with 91.9% in the mandible with an average size of 5.5 cm2 and increased in women. Within a mean follow-up time of 3.6 years the recurrence rate was 36.9%, on average after 36 months. Recurrences were most frequently diagnosed at the age of 31-50 (43.9%). Despite numerous studies, there is still no unanimous opinion on an effective therapy for OKC. However, precise resection of OKC can be facilitated by preoperative 3D-imaging and virtual planning.

The Effectiveness of a Four-Week Online Mindfulness Training Course on Individual Mindfulness Skills and Personal Perception of Stress in Company Employees Working from Home.

Working from home comes with many benefits. However, employees are often exposed to various stressors when working outside of the traditional workplace environment. The subjective experience of these stressors is related to one's perception of the situation and the perceived resources available. As working from home has become the new normal for many during the COVID-19 pandemic, it is in the interest of companies to provide employees with tools to cope with these stressors. One such tool is online mindfulness training. This study investigates how a four-week online mindfulness training influences an individual's mindfulness skills, subjective perception, and processing of stressors. Forty participants working from home at the time of the study were examined in a pre-test using a pre-post design in which the experimental group participated in a four-week online training course in mindfulness. Since the results showed a significantly reduced subjective perception of stress in the experimental group after mindfulness training, a long-term study was conducted including 40 additional participants. The study revealed a training success of at least three months. It thus introduces new possibilities for effective stress management in all workplace settings.

When Do Narcissists Burn Out? The Bright and Dark Side of Narcissism in Surgeons.

This study addresses narcissism as an important psychological factor for the prediction of burnout. Previous research has produced inconsistent findings on whether narcissism is beneficial or detrimental to the development of burnout which is due to the fact that narcissism is viewed as an overall construct rather than on a dimensional level. This study applied a two-dimensional approach to narcissism in burnout. Three hundred-fifty-two surgeons from Germany were asked to complete the Maslach Burnout Inventory and the Narcissistic Admiration and Rivalry Questionnaire. Linear regression analyses revealed that high scores in admiration predicted high personal fulfillment, low emotional exhaustion, and depersonalization. For rivalry, the opposite picture emerged. The results indicate that admiration seems to have a protecting effect, whereas rivalry appears to promote burnout severity.

Primary Orbital Reconstruction with Selective Laser Melting (SLM) of Patient-Specific Implants (PSIs): An Overview of 96 Surgically Treated Patients.

Contemporary advances in technology have allowed the transfer of knowledge from industrial laser melting systems to surgery; such an approach could increase the degree of accuracy in orbital restoration. The aim of this study was to examine the accuracy of selective laser melted PSIs (patient-specific implants) and navigation in primary orbital reconstruction. Ninety-six patients with orbital fractures were included in this study. Planned vs. achieved orbital volumes (a) and angles (b) were compared to the unaffected side (n = 96). The analysis included the overlay of post-treatment on planned images (iPlan 3.0.5, Brainlab®, Feldkirchen, Germany). The mean difference in orbital volume between the digitally planned orbit and the postoperative orbit was 29.16 cm3 (SD 3.54, presurgical) to 28.33 cm3 (SD 3.64, postsurgical, t = 5.00, df = 95.00; p < 0.001), resulting in a mean volume difference (planned vs. postop) of less than 1 cm3. A 3D analysis of the color mapping showed minor deviations compared to the mirrored unaffected side. The results suggested that primary reconstruction in complex orbital wall fractures can be routinely achieved with a high degree of accuracy by using selective laser melted orbital PSIs.

Optogenetic stimulation of lateral hypothalamic orexin/dynorphin inputs in the ventral tegmental area potentiates mesolimbic dopamine neurotransmission and promotes reward-seeking behaviours.

Reward and reinforcement processes are critical for survival and propagation of genes. While numerous brain systems underlie these processes, a cardinal role is ascribed to mesolimbic dopamine. However, ventral tegmental area (VTA) dopamine neurons receive complex innervation and various neuromodulatory factors, including input from lateral hypothalamic (LH) orexin/hypocretin neurons which also express and co-release the neuropeptide, dynorphin. Dynorphin in the VTA induces aversive conditioning through the Kappa opioid receptor (KOR) and decreases dopamine when administered intra-VTA. Exogenous application of orexin or orexin 1 receptor (oxR1) antagonists in the VTA bidirectionally modulates dopamine-driven motivation and reward-seeking behaviours, including the attribution of motivational value to primary rewards and associated conditioned stimuli. However, the effect of endogenous stimulation of LH orexin/dynorphin-containing projections to the VTA and the potential contribution of co-released dynorphin on mesolimbic dopamine and reward related processes remains uncharacterised. We combined optogenetic, electrochemical, and behavioural approaches to examine this. We found that optical stimulation of LH orexin/dynorphin inputs in the VTA potentiates mesolimbic dopamine neurotransmission in the nucleus accumbens (NAc) core, produces real time and conditioned place preference, and increases the food cue-directed orientation in a Pavlovian conditioning procedure. LH orexin/dynorphin potentiation of NAc dopamine release and real time place preference was blocked by an oxR1, but not KOR antagonist. Thus, rewarding effects associated with optical stimulation of LH orexin/dynorphin inputs in the VTA are predominantly driven by orexin rather than dynorphin.

[Validation of the Düsseldorfer screening tool: a trait-based approach to assess psychological distress of cancer patients]. / Validierung des Düsseldorfer Screeningtools: ein traitbasierter Ansatz zur Erfassung der psychischen Belastung von Krebspatienten.

BACKGROUND: Psycho-oncological screening is a useful tool to ascertain whether patients need special support. Currently, patients are asked mainly about their acute problems. Stable internal and external risk factors and preventive patient characteristics are largely disregarded. The newly developed Düsseldorf Screening Tool (DST) captures distress through stable traits, social support, and the patient's coping style. The aim of this study was to validate the DST using the Distress-Thermometer (DT) and Basic Documentation for Psycho-Oncology (PO-Bado). METHODS: A total of 126 patients with head and neck squamous cell carcinoma were investigated. To determine the cut-off value, receiver operating curves (ROC) curves were calculated. As a measure of quality, area under the curve (AUC) values are given. Sensitivity and specificity were established for each gold standard questionnaire. RESULTS: Compared to the DT and PO-Bado, the discrimination ability of the DST is good, with AUC values of 0.62 to 0.80. With a DT cut-off value of 5, a sensitivity of 84.2% with a specificity of 37.0% can be stated. Compared to PO-Bado, a sensitivity value of 92.9% with a specificity of 43.6% can be reported. CONCLUSION: The results show that a trait-based approach to identify patients' level of psychological distress can purposefully and safely assess cancer patients' stress level. A new approach to screening in psycho-oncology has thus emerged.

Determinants of quality of life from the perspective of the patients: A qualitative analysis of patients with oral cavity cancer.

PURPOSE: The aim of this study was to identify factors from the patient's perspective that influence quality of life and psychological stress after oral cancer, and to find out if these patients would opt for psycho-oncological assistance during further treatment. MATERIALS AND METHODS: Standardized interviews were conducted. All interviews were transcribed and reduced according to previously established rules. Next, the patients' statements were coded, put into one format, and summarized in categories. Each category was described individually so that a rule-based quantitative and qualitative evaluation of the patients' statements was then possible. RESULTS: 50 patients were interviewed. 40 of these patients indicated that their own personality and the social support received through friends and family were the most important predictors for quality of life and coping. Therefore, they suggested a focus on these aspects during psycho-oncological treatment. Nearly every patient stated that psycho-oncological assistance should be available for each of them. CONCLUSION: The results of this study show that patients have clear ideas about the factors that influence their quality of life, and that play a role in coping with disease. Doctors and nursing staff should also understand these factors in order to support patients in the best possible way in the context of psychological first aid.

Does autofluorescence help detect recurrent squamous cell carcinoma? A prospective clinical study.

OBJECTIVE: In oral squamous cell carcinoma (OSCC), 20% of patients experience local recurrences. In this study, the addition of autofluorescence to a standard incandescent light examination was evaluated to enhance detection rates of recurrences in OSCC. STUDY DESIGN: Patients with OSCC who underwent follow-up examinations were included in this prospective cohort study. All patients (with or without recurrences) were examined clinically and with autofluorescence (using VELscope; Mectron, Cologne, Germany) and biopsy was used to examine suspect lesions for recurrences. Variables likely to influence results were analyzed. An analysis of dependencies, a general log-linear analysis, and a binary regression analysis were performed using SPSS version 26 (SPSS Inc., Chicago, IL). RESULTS: The study included 195 patients and in 39 cases a biopsy was performed. Results showed significantly more recurrences with the addition of autofluorescence to the usual clinical examination (P ≥ .5). Sensitivity was 95.2% and specificity was 100%. CONCLUSIONS: This study showed the advantages of adding autofluorescence to routine clinical assessments in OSCC follow-up examinations.

A Systematic Review of Sexual Satisfaction in Prostate Cancer Patients.

INTRODUCTION: Prostate cancer (PCa) treatment has a significant negative impact on sexual function. Because research to this date has mostly focused on the impact of PCa on erectile function, very little is known about the impact of PCa on other relevant sexual outcomes, such as sexual satisfaction. AIM: To conduct a literature review of studies that have examined sexual satisfaction in men diagnosed with and treated for PCa. METHODS: A systematic review was conducted using Scopus and PubMed databases to identify studies that had assessed sexual satisfaction in men with PCa. The main characteristics of each study and results regarding the impact of PCa on sexual satisfaction were extracted and examined. MAIN OUTCOME MEASURE: The main outcome measure was studies that assessed general sexual satisfaction in men with PCa. RESULTS: Thirty-eight articles were found regarding sexual satisfaction in PCa. Most studies did not focus on sexual satisfaction specifically, and methodologic limitations produced very mixed results. Overall, PCa treatments had a low to moderate impact on sexual satisfaction, and psychosocial interventions were more successful at improving sexual satisfaction than medical interventions. Sexual satisfaction was correlated to a large number of sexual, relational, psychological, and medical variables. CONCLUSION: This literature review shows very mixed results about the sexual satisfaction in men with PCa. Differences in research designs, methodologic limitations, and studies conducted atheoretically limit our understanding of the mechanisms that impact sexual satisfaction in men with PCa. We propose an alternative way of conducting research on sexual satisfaction by using solid theoretical models of sexual satisfaction. Santos-Iglesias P, Rana M, Walker L.

Trajectory-guided biopsy of orbital tumor - Technology, principal considerations and clinical implementation.

Intraorbital space-occupying lesions always pose a challenge, both in terms of definite surgical removal as well as preoperative sampling for histopathological examination. Despite the use of modern high-resolution imaging techniques, the dignity of orbital lesions can often not be determined with sufficient certainty preoperatively. As the amount and complexity of treatment possibilities continue to increase, detailed diagnostics in advance of treatment choice are essential. Histological classification of orbital lesions can still be considered the gold standard for reliable diagnoses, leading to appropriate treatment. Over recent years minimally invasive surgical approaches have gained more importance in the treatment and diagnosis of cranio-maxillo-facial tumor and trauma. The aim of our study was to adapt and establish a precise procedure for orbital biopsies. 23 patients suffering from space-occupying lesions of unknown dignity were included. Trajectory-guided procedures were pre-planned for all cases. In most cases minimally invasive procedures were suitable for taking biopsies of the orbit. For only two patients a conventional, non-minimally invasive, lateral orbitotomy had to be performed. Further evaluation of the presented procedure demonstrates clearly that trajectory-guided biopsies of the orbit can be performed correctly and effectively, regardless of the suspected lesion's size.

Screening for psychological distress: A new approach to identify the patient's psychological needs in a pilot study on oral cancer patients.

OBJECTIVE: A new screening tool has been developed to predict the psychological needs of patients with oral cancer. METHOD: The new screening method was developed inductively. Screening was pretested using interviews and implemented with 71 patients with oral cancer. Factor analysis was carried out to shorten the questionnaire. RESULTS: Negative and positive aspects explain forty per cent of the variance in distress, which should be adequate for a first screening. Seventy-nine per cent of the items deal with stable traits such as personality. The patients' objective need for support has to be another important part of this new screening. CONCLUSIONS: Personality and other traits are good predictors for psychological distress. Longitudinal studies need to assess these new aspects of screening cancer patients to find out if they need psycho-oncological support.

Doctors' tacit knowledge on coping processes of oral cancer patients: A qualitative study.

PURPOSE: The implicit knowledge of doctors about coping, quality of life and factors which have an influence on these aspects were investigated. In addition, they were asked about the need for psychological support in clinical practice. MATERIAL AND METHODS: Doctors (n = 40) working in the field of oral and maxillofacial surgery, otorhinolaryngology and oncology were interviewed about coping and quality of life of patients, the course of therapy and experiences in the doctor-patient interaction based on a semi-structured interview. The data were analyzed using qualitative content analysis. RESULTS: Hundred percent of the doctors pointed out that patients with oral cancer are a special clientele which definitely needs to have psycho-oncological support. Eighty seven percent of the doctors divide their patients based on their style of coping into two groups: the one who are depressive and do not cope well and active patients who are able to stand their diagnosis. Ninety five percent of the doctors cite personality and social support as key factors affecting the quality of life and style of coping. Lack of time and lack of support from psychologists were given as the main obstacle for holistic treatment. CONCLUSIONS: Doctors have very specific ideas about the coping mechanisms and problems of their patients. These theories may have an impact on the doctor-patient relationship and should be considered in more detail.

Relevance of psychosocial factors to quality of life in oral cancer and oral lichen planus: a prospective comparative study.

We can improve our understanding of how patients cope with oral squamous cell carcinoma (SCC) by making a comparison with their processes of coping and those used in other conditions. We have therefore compared quality of life (QoL), severity of symptoms, coping strategies, and factors that influence coping between patients with oral SCC and those with oral lichen planus. We asked 104 patients with oral SCC and 51 with oral lichen planus to complete questionnaires about their coping strategies, social support, locus of control, spirituality, QoL, and severity of symptoms. The outcome was that patients with oral SCC were far more likely to resort to coping strategies such as depressive coping, distraction, and self-motivation. The groups also differed regarding QoL and severity of symptoms. Patients with oral SCC had a poorer QoL and higher depression scores, whereas patients with oral lichen planus had better scores in the social support and spirituality categories. Patients with oral SCC generally had more distress than those with oral lichen planus. Not only did the former resort to depressive coping strategies, but they also had poorer QoL and higher values for depression. For the patients with oral lichen planus, social support and spirituality were protective, whereas they were associated with distress by patients with oral SCC.

Increasing the accuracy of orbital reconstruction with selective laser-melted patient-specific implants combined with intraoperative navigation.

PURPOSE: Advances in technology have allowed increasing degrees of accuracy in the treatment of orbital deformities. The purpose of this study was to compare the accuracy of pre-bent titanium mesh (PBTM) and selective laser-melted patient-specific implants (PSIs) in unilateral orbital reconstruction after traumatic injury. The authors hypothesized that selective laser-melted PSIs would more accurately reconstruct the orbit. MATERIALS AND METHODS: A retrospective review of 34 cases of primary reconstruction of unilateral orbital fractures treated using selective laser-melted PSIs (group 1, n = 17) or PBTM (group 2, n = 17) was performed. The primary outcome measurements were orbital volume excess and the anterior, medial, and posterior intraorbital angles. The Mann-Whitney U test was used to assess the difference in orbital volume and angular deviation between the 2 groups. The level of statistical significance was set at .05. All P values were 2-sided. RESULTS: The comparison of mean values for the 2 groups showed significant differences for the anterior angle (PBTM: mean, 11.3; standard deviation [SD], 1.8; PSI: mean, 4.1; SD, 0.7; P = .001), but not the medial (PBTM: mean, 11.6; SD, 2.0; PSI: mean, 8.2; SD, 1.9; P = .170) and posterior (PBTM: mean, 10.8, SD, 2.8; PSI: mean, 8.2, SD, 1.4; P = .760) angles between the unaffected and reconstructed orbits. The postoperative difference in volume between the unaffected and reconstructed orbits differed significantly between the 2 study groups (PBTM: mean, 0.6; SD, 0.1; PSI: mean, 0.4; SD, 0.1; P = .029). CONCLUSION: The results of this study suggest that complex orbital fractures can be reconstructed with an even higher degree of accuracy with selective laser-melted PSIs than with PBTM.

Coping with stroke: a prospective comparative cross-cultural research.

In the present study, the coping strategies of stroke patients were examined. An intercultural comparison between patients from Germany and Pakistan was made to investigate the impact of culture on coping processes and the need to consider these in the therapy of stroke patients. Six self-completed questionnaires were given to 53 stroke patients from Germany and 44 from Pakistan. In addition to coping processes, potential determinants on coping such as religiosity, social support and locus of control were examined. Analysis suggested both samples to be characterized by similar coping processes,but the German and Pakistani patients eventually differ in the extent they use these psychosocial determinants. This study provides modern treatment strategies for coping with stroke.

Development and evaluation of an automatic tumor segmentation tool: a comparison between automatic, semi-automatic and manual segmentation of mandibular odontogenic cysts and tumors.

INTRODUCTION: In the treatment of cancer in the head and neck region, computer-assisted surgery can be used to estimate location and extent by segmentation of the tumor. This article presents a new tool (Smartbrush), which allows for faster automated segmentation of the tumor. METHODS: This new method was compared with other well-known techniques of segmentation. Thirty-eight patients with keratocystic odontogenic tumors were included in this study. The tumors were segmented using manual segmentation, threshold-based segmentation and segmentation using Smartbrush. All three methods were compared concerning usability, time expenditure and accuracy. RESULTS: The results suggest that segmentation using Smartbrush is significantly faster with comparable accuracy. CONCLUSIONS: After a period of adjustment to the program, one can comfortably get reliable results that, compared with other methods, are not as dependent on the user's experience. Smartbrush segmentation is a reliable and fast method of segmentation in tumor surgery.

Religious Confession and Symptom Severity: A Prospective Comparative Study.

Little research has been done on comparing confessions regarding mental health. In the present study, 320 people (78 Buddhists, 77 Catholics, 89 Protestants and 79 Muslims) were compared in terms of their symptom severity. Buddhists and Protestants had lower scores than Catholics and Muslims for obsessive-compulsive behavior and hostility. Muslim group had the highest comparative scores for psychoticism. Buddhists and Protestants had comparatively low scores for paranoid ideation and overall symptom severity, with Catholics and Muslims having high ones. Results reveal that confession should be taken in account in psychological research and diagnosis, since it is explicitly associated with psychological well-being.

Comparison of health-related quality of life of patients with different precancer and oral cancer stages.

OBJECTIVES: Health-related quality of life (HR-QoL) informations are becoming an important tool for the treatment concept for cancer patients. The purpose of this study was to evaluate how the quality of life depends on the disease severity of pre- and oral cancer patients and which factors influence their quality of life. MATERIALS AND METHODS: During this study, 106 patients with a premalignant oral lesion, 174 patients with oral squamous cell carcinoma (OSSC) as well as 21 patients with a recurrence of OSSC were asked about their oral health-related quality of life. Additionally, the UW-QOLv4 was used to record the psychological and clinical symptoms from which the patients of the three groups are suffering. RESULTS: Significant differences with respect to oral HR-QoL of life between the groups could be evaluated. Patients with a recurrence have the lowest and patients with precancer the highest HR-QoL. Within the groups, there is a difference regarding the significance of the psychological factors. The lowest values were achieved for mood within all three groups. Anxiety is of key importance for the precancer group whereas appearance and activity are of importance for the patients having a tumor. The patients of the recurrence group are heavily affected by all factors. CONCLUSIONS: The quality of life differs depending on the disease. The patients of the recurrence group have the lowest oral health-related quality of life for all aspects analyzed, and they are suffering the most with respect to the psychological dimensions of the UW-QOLv4. CLINICAL RELEVANCE: The present study examined the quality of life depending on the severity of the disease of pre- and oral cancer patients and which factors significantly influenced their quality of life. The evaluated findings of relevant variables may have therapeutic relevance for the multidisciplinary treatment of oral cancer patients in the future.
