Patients' perioperative experiences of an opioid-free versus opioid-based care pathway for laparoscopic bariatric surgery: A qualitative study.

Background: Despite recent evidence supporting the adoption of opioid-free anaesthetic and analgesic alternatives in the perioperative context, opioid-based regimens remain standard of care. There is limited knowledge about the patients' perioperative experiences of bariatric surgery, with no study yet investigating their experiences within an opioid-free care pathway. Objective: We aimed to describe similarities and differences in patients' perioperative experiences of undergoing bariatric surgery with either an opioid-free or opioid-based care pathway. Design: A qualitative interview study. Setting: A strategic sample of patients enrolled in an ongoing randomized controlled trial investigating the effects of opioid-free anaesthesia for bariatric surgery were recruited. In the randomized controlled trial, participants were randomized to either opioid-based anaesthesia or opioid-free anaesthesia, including transcutaneous electrical nerve stimulation as primary postoperative pain management. Participants: Twenty patients were interviewed 3 months after surgery: 10 participants in the opioid-free group versus 10 in the opioid-based group. Methods: Semi-structured interviews were conducted between December 2020 and February 2022 and analysed with qualitative content analysis. Results: The analysis yielded four categories and 12 subcategories. In Category 1, participants shared diverse emotions before surgery, including anticipation of a healthier life, but also apprehensions and feelings of failure. In Category 2, describing liminality of general anaesthesia, there were similar descriptions of struggling to remember the anaesthesia induction and struggling to surface when recovering from anaesthesia. However, some participants in the opioid-free group shared descriptions of struggling to keep control, describing accentuated memories of the anaesthesia induction. Category 3, managing your pain, showed similar experiences and strategies but different narrations of pain management, with the opioid-free group stating that transcutaneous electrical nerve stimulation works but not when it really hurts, and the opioid-based group describing confidence in but awareness of opioids. Throughout the overall perioperative time period, participants acknowledged Category 4, a patient-professional presence, stating that preparations boost the feeling of confidence before surgery and that they felt confidence in a vulnerable situation although vulnerability challenges communication. Conclusions: We highlighted the overall similarities in perioperative experiences of patients undergoing bariatric surgery. However, the differences in experiences during opioid-free anaesthesia induction need to be addressed in further implementation and research studies investigating strategies to reduce the sense of loss of control. More research is needed to facilitate the implementation of opioid-free treatment strategies into clinical practice and improve the patient care experience.

Patient-Centerdness in the Perioperative Period-A Rapid Review of Current Research.

PURPOSE: The indication of surgery is a critical moment in a person's life implying different needs, feelings, or fears. The aim of the current literature review was to elucidate the prevailing utilization of the concepts 'patient-centerdness' and 'person-centerdness' within the perioperative period. DESIGN: A rapid review design. METHODS: Literature searches were conducted in the databases PubMed, Scopus (Elsevier), American Psychological Association PsychInfo (Ovid), Embase (Ovid), CINAHL (Ovid), and Cochrane Library in December 2022. Rayyan software was used to assess the articles. Joanna Briggs Institute critical appraisal tools were used to evaluate the quality of the included articles. Thematic analysis was used to identify themes across the articles. FINDINGS: The electronic database searches identified 1,967 articles. A total of 12 articles were assessed in full text against the inclusion and exclusion criteria, and finally, a total of seven articles were included. The articles originated from six countries, employed disparate methodological approaches, and featured a heterogeneous array of participants representing various health care settings. Patient-centerdness held the mantle as the most prominently used concept across the seven articles, whereas person-centerdness emerged as the least frequently explored concept. One theme was identified across the articles; Preparedness. This was related to shared decision-making and information pre, peri- and postoperative. CONCLUSIONS: This rapid review suggests that patient preparedness, particularly through shared decision-making and providing information, is a recurring theme in the limited studies on patient- or person-centerdness in the perioperative context. The fact that only one single study focuses on person-centered care underscores the pressing need for a comprehensive re-evaluation of modern perioperative care.

Evaluating a targeted person-centred pain management intervention programme in lumbar spine surgery - a controlled segment-specific before-and-after interventional design.

BACKGROUND: Postoperative pain management in lumbar spine surgery care remains a challenge. The aim of this study was to evaluate the impact of a person-centred postoperative pain management intervention programme on lumbar spine surgery patients on postoperative pain, shared decision-making, and satisfaction with postoperative pain management. METHODS: The study was performed with a controlled before-and-after interventional design in an orthopaedic unit at a university hospital. Person-centred pain management for patients undergoing spine surgery was developed in co-creation by a multi-professional team and implemented throughout the care pathway. The usual care group (pre-intervention) served as a comparison to the intervention group. Pain intensity, shared decision-making in pain management, and patient satisfaction with results of pain management, served as patient-reported measures, collected using the International Pain Outcomes questionnaire and analysed using descriptive statistics. RESULTS: The intervention showed no benefit for patients' pain and satisfaction, while shared decision-making in pain management was significant lower in the intervention group than in the conventional group. The per-protocol analysis showed no significant differences between groups. CONCLUSION: The initial assumption of the study, that the implementation of a co-created structured person-centred care pathway would improve patient-reported outcomes, was not confirmed. The periodically low fidelity to the intervention due to organizational constraints (due to sub-optimal organizational conditions and managerial support) may have affected the results.

High-frequency, high-intensity transcutaneous electrical nerve stimulation compared with opioids for pain relief after gynecological surgery: a systematic review and meta-analysis.

OBJECTIVES: Opioids are important for postoperative analgesia but their use can be associated with numerous side effects. Transcutaneous electrical nerve stimulation (TENS) has been used for acute pain treatment and has dose-dependent analgesic effects, and therefore presents an alternative to intravenous (iv) opioids for postoperative pain relief. The aim of this meta-analysis was to compare high-frequency, high-intensity (HFHI or intense) TENS to iv opioids with regard to postoperative pain intensity, recovery time in the Post Anesthesia Care Unit (PACU) and opioid consumption after elective gynecological surgery. METHODS: We searched Medline, Embase, Web of Science, Cochrane, Amed and Cinahl for RCTs and quasi-experimental studies (2010-2022), and WHO and ClinicalTrials.gov for ongoing/unpublished studies. Meta-analysis and subsequent Trial Sequential Analysis (TSA) was performed for all stated outcomes. Quality of evidence was assessed according to GRADE. RESULTS: Only three RCTs met the inclusion criteria (362 participants). The surgical procedures involved surgical abortion, gynecologic laparoscopy and hysteroscopy. The applied TENS frequency was 80 Hz and intensity 40-60 mA. There was no difference in pain intensity according to Visual Analogue Scale (VAS) at discharge from PACU between the TENS and opioid group (MD VAS -0.15, 95 % CI -0.38 to 0.09) (moderate level of evidence). Time in PACU was significantly shorter in the TENS group (MD -15.2, 95 % -22.75 to -7.67), and this finding was manifested by TSA (high-level of evidence). Opioid consumption in PACU was lower in the TENS group (MD Morphine equivalents per patient mg -3.42, 95 % -4.67 to -2.17) (high-level of evidence). CONCLUSIONS: There was no detectable difference in postoperative pain relief between HFHI TENS and iv opioids after gynecological surgery. Moreover, HFHI TENS decreases recovery time and opioid consumption in PACU. HFHI TENS may be considered an opioid-sparing alternative for postoperative pain relief after gynecological surgery.

Distinct Chemokine Receptor Expression Profiles in De Novo DLBCL, Transformed Follicular Lymphoma, Richter's Trans-Formed DLBCL and Germinal Center B-Cells.

Chemokine receptors and their ligands have been identified as playing an important role in the development of diffuse large B-cell lymphoma (DLBCL), follicular lymphoma, and Richter syndrome (RS). Our aim was to investigate the different expression profiles in de novo DLBCL, transformed follicular lymphoma (tFL), and RS. Here, we profiled the mRNA expression levels of 18 chemokine receptors (CCR1-CCR9, CXCR1-CXCR7, CX3CR1 and XCR1) using RQ-PCR, as well as immunohistochemistry of seven chemokine receptors (CCR1, CCR4-CCR8 and CXCR2) in RS, de novo DLBCL, and tFL biopsy-derived tissues. Tonsil-derived germinal center B-cells (GC-B) served as non-neoplastic controls. The chemokine receptor expression profiles of de novo DLBCL and tFL substantially differed from those of GC-B, with at least 5-fold higher expression of 15 out of the 18 investigated chemokine receptors (CCR1-CCR9, CXCR1, CXCR2, CXCR6, CXCR7, CX3CR1 and XCR1) in these lymphoma subtypes. Interestingly, the de novo DLBCL and tFL exhibited at least 22-fold higher expression of CCR1, CCR5, CCR8, and CXCR6 compared with RS, whereas no significant difference in chemokine receptor expression profile was detected when comparing de novo DLBCL with tFL. Furthermore, in de novo DLBCL and tFLs, a high expression of CCR7 was associated with a poor overall survival in our study cohort, as well as in an independent patient cohort. Our data indicate that the chemokine receptor expression profile of RS differs substantially from that of de novo DLBCL and tFL. Thus, these multiple dysregulated chemokine receptors could represent novel clinical markers as diagnostic and prognostic tools. Moreover, this study highlights the relevance of chemokine signaling crosstalk in the tumor microenvironment of aggressive lymphomas.

Total opioid-free general anaesthesia can improve postoperative outcomes after surgery, without evidence of adverse effects on patient safety and pain management: A systematic review and meta-analysis.

BACKGROUND: Opioid-based treatment is used to manage stress responses during surgery and postoperative pain. However, opioids have both acute and long-term side effects, calling for opioid-free anaesthetic strategies. This meta-analysis compares adverse events, postoperative recovery, discharge time from post-anaesthesia care unit, and postoperative pain, nausea, vomiting, and opioid consumption between strict opioid-free and opioid-based general anaesthesia. METHODS: We conducted a systematic review and meta-analysis. We searched PubMed, Embase, Cinahl, Cochrane Library, selected reference lists, and Google Scholar. We included randomised controlled trials (RCTs) published between January 2000 and February 2021 with at least one opioid-free study arm, i.e. no opioids administered preoperatively, during anaesthesia induction, before skin closure, or before emergence from anaesthesia. RESULTS: The study comprised 1934 patients from 26 RCTs. Common interventions included laparoscopic gynaecological surgery, upper gastrointestinal surgery, and breast surgery. There is firm evidence that opioid-free anaesthesia significantly reduced adverse postoperative events (OR 0.32, 95% CI 0.22 to 0.46, I2  = 56%, p < 0.00001), mainly driven by decreased nausea (OR 0.27, (0.17 to 0.42), p < 0.00001) and vomiting (OR 0.22 (0.11 to 0.41), p < 0.00001). Postoperative opioid consumption was significantly lower in the opioid-free group (-6.00 mg (-8.52 to -3.48), p < 0.00001). There was no significant difference in length of post-anaesthesia care unit stay and overall postoperative pain between groups. CONCLUSIONS: Opioid-free anaesthesia can improve postoperative outcomes in several surgical settings without evidence of adverse effects on patient safety and pain management. There is a need for more evidence-based non-opioid anaesthetic protocols for different types of surgery as well as postoperative phases.

Preservation of nasal turbinates in endoscopic, anterior skull base surgery-yes, we can!

OBJECTIVE: To evaluate the frequency, type and indications of nasal turbinate (NT) resection during endoscopic, anterior skull base surgery and to analyze factors that may have an impact on the need of NT removal. METHODS: In this retrospective cohort study, 306 subjects (150 males and 156 females, mean age 55.4 ± 15.3 years) who underwent multidisciplinary, transnasal, endoscopic tumor surgery of the anterior skull base using 4-handed techniques between 2011 and 2019 at the Department of Otorhinolaryngology, Medical University of Graz, were included. RESULTS: In the majority of interventions (n = 281/306; 91.8%), all NT were preserved. Significant factors influencing the need of NT resections turned out to be type of endoscopic approach (p < 0.001; V = 0.304), sagittal (p = 0.003; d = 0.481) and transversal (p = 0.017; d = 0.533) tumor diameter, tumor type (p < 0.001; V = 0.355) and tumor location (p < 0.001; V = 0.324). CONCLUSIONS: NT can be preserved in the majority of patients undergoing tumor resection in anterior, transnasal, skullbase surgery and routine resection of NT should be avoided. Variables that have an impact on the need of NT resections are types of endoscopic approaches, sagittal and transversal tumor extension and tumor type. These factors should be considered in planning of surgery and preoperative information of patients.

Comparison of two different intratympanic corticosteroid injection protocols as salvage treatments for idiopathic sudden sensorineural hearing loss.

PURPOSE: We aimed to investigate the effect of interval length and total count of intratympanic steroid (ITS) injections in salvage treatment of patients with idiopathic sudden sensorineural hearing loss (ISSNHL). METHODS: This retrospective case-control study included 64 patients with ISSNHL, who were treated with ITS injections as salvage therapy at a tertiary referral centre. From September 2019 to December 2020, 32 patients received up to four injections every 2-4 days (revised-protocol group). These patients were 1:1 matched to patients, who received up to three injections at 1-week intervals between January 2014 and August 2019 (initial-protocol group). Hearing outcomes of the two groups were compared. RESULTS: Both ITS salvage treatment protocols resulted in a statistically significant hearing improvement (p < 0.05). The initial-protocol declined hearing thresholds by 12 ± 11.7 dB (p < 0.001, d = 1, P = 99%). Mean hearing function was improved by 13.4 ± 19.1 dB in the revised-protocol group [p < 0.001, d = 0.7, P = 98%]. A clinically significant hearing improvement (> 10 dB) was seen in 18 patients (58.1%) in the initial-protocol group and in 14 patients (41.9%) in the revised-protocol group. A comparison of the hearing outcomes between protocol groups revealed no statistically significant differences (p > 0.05). CONCLUSION: These results indicate that a shorter injection interval does not lead to better hearing outcomes in ITS salvage treatment for ISSNHL. Moreover, fewer ITS injections may reduce costs, physical/mental stress of the patients and lower the risk of persistent tympanic perforations.

Opioid consumption in patients undergoing Roux-en-Y bariatric surgery compared with population controls with and without obesity.

BACKGROUND: Patients with obesity are prescribed more opioids than the general population. OBJECTIVES: To compare opioid consumption in patients with obesity who underwent Roux-en-Y bariatric surgery (RYGB) with population controls with and without obesity, not undergoing bariatric surgery, and to identify characteristics associated with opioid use. SETTING: This study included all patients with a principal diagnosis of obesity, aged 18-72 years, with a RYGB surgical code in the Swedish Patient Register between 2007 and 2013. METHODS: RYGB patients (n = 23,898) were age- and sex-matched with 1 control patient with obesity (n = 23,898) and 2 population controls without obesity (n = 46,064). Participants were classified as nonconsumers and consumers based on their opioid dispensations during the 12 months before baseline. Opioid consumption was assessed for 24 months. RESULTS: Nonconsumers. Within 24 months, a significantly higher proportion of RYGB patients (16.6%) started using opioids compared with the controls with obesity (14.3%, P < .0001) and population controls (5.4%, P < .0001). RYGB patients and controls with obesity had higher median daily intake of opioid morphine equivalent (MEQ) (2.8 mg/d) than population controls (2.5 mg/d, P < .0001). Consumers. Within 24 months, the proportion of RYGB patients and controls with obesity that was using opioids were similar (53.1% and 53.4%), but higher compared to population controls (38.0%, P < .0001). The median daily opioid MEQ was higher among RYGB patients than in population controls (10.5 versus 7.8 mg/d, P < .0001). RYGB patients, overall, had higher incidence of bowel surgery and cholecystectomy compared with controls with obesity and population controls, leading to prolonged opioid use in this group. Opioid consumption in general was associated with chronic pain and psychiatric disorder, which were more common in patients with obesity than in the population controls. CONCLUSION: RYGB surgery increased the risk of prolonged opioid use in patients with obesity who were nonconsumers before surgery but had no effect on overall opioid use among prior consumers. RYGB-associated complications requiring surgery influenced opioid use for both nonconsumers and consumers. Regular reassessments of pain mechanisms and specific treatment owing to type of pain could prevent unnecessary opioid use in this patient group.

The impact of implementing a person-centred pain management intervention on resistance to change and organizational culture.

BACKGROUND: Resistance to change and organizational culture are essential factors to consider in change management in health care settings. Implementation of structural change remains a challenge. There is a lack of studies providing information on the impact of implementation processes on the organization. The aim of this study was to describe the impact of implementing a systematic change process concerning postoperative person-centred pain management on resistance to change and organizational culture in an orthopaedic spine surgery unit. METHODS: The study was set in an orthopaedic spine surgery unit at a university hospital. Person-centred bundles of care for postoperative pain management of spine surgery patients were developed in co-creation by a multi-professional expert group and implemented throughout the care pathway. The intervention was underpinned by theories on organizational culture and inspired by principles of person-centred care. Quantitative data were collected using the Resistance to Change Scale and the Organizational Culture Assessment Instrument and analysed using descriptive statistics. RESULTS: The findings showed a low resistance to change decreasing during the study. The organizational culture shifted from a result-oriented to a formalized and structured culture after the implementation. The culture preferred by the staff was team-oriented and participation-focused throughout the study. The discrepancy between the current and preferred cultures remained extensive over time. CONCLUSION: It is challenging to describe the influence of the development and implementation of a postoperative pain management program on organizational culture as well as in terms of resistance to change, in a complex health care setting. In the current study the unit was under organizational strain during the implementation. Albeit, the important discrepancy between the current and preferred organizational culture could imply that structural changes aren't enough when implementing person-centred pain management structures and needs to be combined with relational aspects of change.

Managerial and organisational prerequisites for the integration of palliative care in the intensive care setting: A qualitative study.

AIM: To explore the association of organizational structures when integrating palliative care in intensive care units. BACKGROUND: Palliative care within intensive care settings has been widely recognized as an area requiring improvement when caring for patients and their families. Despite this, intensive care units continue to struggle to integrate palliative care. METHODS: A qualitative descriptive methodology was used. Data were collected through research interviews with 15 managers and 36 health care professionals working in intensive care. The data were analysed adopting constant comparative analysis. RESULTS: This study provides insight into a diverse range of perspectives on organizational structure in the context of facilitation and the challenges posed. Three themes were identified: Do not resuscitate policy as a gateway to palliative care, facilitating family members to enable participation and support and barriers for palliative care in intensive care unit as a result of intensive care organization. CONCLUSIONS: In fostering a sustainable organizational culture and practice development in intensive care, the findings indicate the need for specific palliative care policies and implementation strategies tailored according to context. IMPLICATIONS FOR NURSING MANAGEMENT: Management has a responsibility to facilitate dialogue within any multidisciplinary team regarding palliative care and, in particular, to focus on 'do not resuscitate' policies as a gateway into this conversation.

Sinonasal mucosal melanoma: treatment strategies and survival rates for a rare disease entity : A single center experience and review of literature.

BACKGROUND: Sinonasal mucosal melanoma (SNMM) is a rare disease entity comprising 0.4-1.3% of all melanomas. Surgery with free margins has been the primary treatment over decades. Neither the addition of radiotherapy nor chemotherapy could significantly improve outcome rates of this devastating malignancy. This study presents our clinical experience with SNMM over a 19-year period and summarizes the current body of literature on SNMM. METHODS: This retrospective analysis included 12 patients with SNMM treated from 2001 to 2019 at an academic center. Additionally, a literature review of the last 29 years on treatment and survival data of SNMM was conducted. RESULTS: Main initial symptoms were epistaxis and nasal obstruction. Of the patients 9 underwent endoscopic surgery, 6 received adjuvant therapy. 3 patients who did not undergo surgery, received chemoradiotherapy, radiotherapy alone, and chemotherapy alone, respectively. At the time of diagnosis 2 patients had distant metastases and 4 patients developed distant metastases during the course of the disease. Mean overall survival (OS) was 30.6 months, 3­year and 5­year OS were 25%, and 18.2%, respectively. CONCLUSION: Unspecific symptoms and hidden anatomic locations lead to delayed diagnosis and increased rates of metastatic dissemination. Distant metastasis is the main treatment failure in SNMM. Surgery with free margins remains the primary treatment for SNMM. Adjuvant radiotherapy might improve local control in individual cases but efficient systemic therapy is needed to improve outcome rates. To evaluate and define more effective targeted treatment options and improve outcome rates, homogeneous data and prospective multicentric analysis are needed.

Patients' experiences of everyday living before and after transcatheter aortic valve implantation.

BACKGROUND: Aortic stenosis (AS) is the most common valvular disease in western countries. Unless treated, it is associated with a poor prognosis. Surgical aortic valve replacement, the gold-standard approach, aims to increase survival and improve quality of life. In recent years, though, transcatheter aortic valve implantation (TAVI) has become the treatment of choice in elderly, high-risk patients who are denied open surgery. To date, however, little is known about their personal psychological experience after undergoing TAVI. AIM: This study aimed to explore patients' experiences during everyday life before and after TAVI. METHOD: Altogether, 14 elderly Swedish patients (9 women, 5 men), treated with TAVI, were interviewed between 2 and 6 months after the implantation. The interviews were analysed using qualitative content analysis. RESULTS: Analysis of the participants' experiences was divided into two domains: before and after, that is, life with AS vs. life after TAVI. From these domains, four categories were derived: (1) adapting to the deteriorating self; (2) feeling disconnected; (3) reconstruction of self; and (4) processing disappointment. CONCLUSIONS: Transcatheter aortic valve implantation involves not only adding years to life but also adding life to years. The urge to live an autonomous life in a social context with others is an important argument for undergoing a TAVI procedure. Despite severe illness and demanding rehabilitation, elderly TAVI patients have the ability to regain independence and rebuild their lives when they base their decision to undergo TAVI on personal goals. These findings might be helpful when implementing person-centred care.

Volumetric Investigation of Sphenoid Sinus in an Elderly Population.

The aims of this study were to determine the sphenoid sinus volume in an Austrian population, evaluate the relationship between volume and different types of pneumatization and investigate possible age-related sphenoid sinus volume degeneration in the elderly. A total of 50 human cadaver including 25 male and 25 female samples (=100 sphenoid sinuses, age range 65-100, mean age 84.52 ±â€Š9.50) were selected to obtain volume and anatomical variants of pneumatization by using sphenoid sinus casts, made of quadrofunctional hydrophilic addition reaction silicone. The mean sphenoid sinus volume was 4.79 ±â€Š2.39 cm. Males showed statistically significant larger sinus volumes than females (P = 0.048). The volume differed statistically significant for the different types of pneumatization (P < 0.001). The combined type of sphenoid sinus pneumatization presented the largest volume with 7.20 cm, followed by lateral, clival, sphenoid body, presellar, and conchal sinus type with 5.72, 5.63, 4.25, 2.08, and 0.5 cm, respectively. No significant correlation between age and sphenoid sinus volume was found (P = 0.707). This study highlights the close relationship between volume and morphology of sphenoid sinus and confirms ethnic variability. Moreover, our data shows no age-related volume degeneration.

Preliminary insights into the impact of primary radiochemotherapy on the salivary microbiome in head and neck squamous cell carcinoma.

Squamous cell carcinoma is the most common type of throat cancer. Treatment options comprise surgery, radiotherapy, and/or chemo(immuno)therapy. The salivary microbiome is shaped by the disease, and likely by the treatment, resulting in side effects caused by chemoradiation that severely impair patients' well-being. High-throughput amplicon sequencing of the 16S rRNA gene provides an opportunity to investigate changes in the salivary microbiome in health and disease. In this preliminary study, we investigated alterations in the bacterial, fungal, and archaeal components of the salivary microbiome between healthy subjects and patients with head and neck squamous cell carcinoma before and close to the end point of chemoradiation ("after"). We enrolled 31 patients and 11 healthy controls, with 11 patients providing samples both before and after chemoradiation. Analysis revealed an effect on the bacterial and fungal microbiome, with a partial antagonistic reaction but no effects on the archaeal microbial community. Specifically, we observed an individual increase in Candida signatures following chemoradiation, whereas the overall diversity of the microbial and fungal signatures decreased significantly after therapy. Thus, our study indicates that the patient microbiome reacts individually to chemoradiation but has potential for future optimization of disease diagnostics and personalized treatments.

Factors influencing the integration of a palliative approach in intensive care units: a systematic mixed-methods review.

BACKGROUND: While a palliative approach is generally perceived to be an integral part of the intensive care unit (ICU), the provision of palliative care in this setting is challenging. This review aims to identify factors (barriers and facilitators) influencing a palliative approach in intensive care settings, as perceived by health care professionals. METHOD: A systematic mixed-methods review was conducted. Multiple electronic databases were used, and the following search terms were utilized: implementation, palliative care, and intensive care unit. In total, 1843 articles were screened, of which 24 met the research inclusion/exclusion criteria. A thematic synthesis method was used for both qualitative and quantitative studies. RESULTS: Four key prerequisite factors were identified: (a) organizational structure in facilitating policies, unappropriated resources, multi-disciplinary team involvement, and knowledge and skills; (b) work environment, including physical and psychosocial factors; (c) interpersonal factors/barriers, including family and patients' involvement in communication and participation; and (d) decision-making, e.g., decision and transition, goal conflict, multidisciplinary team communication, and prognostication. CONCLUSION: Factors hindering the integration of a palliative approach in an intensive care context constitute a complex interplay among organizational structure, the care environment and clinicians' perceptions and attitudes. While patient and family involvement was identified as an important facilitator of palliative care, it was also recognized as a barrier for clinicians due to challenges in shared goal setting and communication.

DRH1 - a novel blood-based HPV tumour marker.

BACKGROUND: To date, no studies have successfully shown that a highly specific, blood-based tumour marker to detect clinically relevant HPV-induced disease could be used for screening, monitoring therapy response or early detection of recurrence. This study aims to assess the clinical performance of a newly developed HPV16-L1 DRH1 epitope-specific serological assay. METHODS: In a multi-centre study sera of 1486 patients (301 Head and Neck Squamous Cell Carcinoma (HNSCC) patients, 12 HIV+ anal cancer patients, 80 HIV-positive patients, 29 Gardasil-9-vaccinees, 1064 healthy controls) were tested for human HPV16-L1 DRH1 antibodies. Analytical specificity was determined using WHO reference-sera for HPV16/18 and 29 pre- and post-immune sera of Gardasil-9-vaccinees. Tumour-tissue was immunochemically stained for HPV-L1-capsidprotein-expression. FINDINGS: The DRH1-competitive-serological-assay showed a sensitivity of 95% (95% CI, 77.2-99.9%) for HPV16-driven HNSCC, and 90% (95% CI, 55.5-99.7%) for HPV16-induced anal cancer in HIV-positives. Overall diagnostic specificity was 99.46% for men and 99.29% for women ≥ 30 years. After vaccination, antibody level increased from average 364 ng/ml to 37,500 ng/ml. During post-therapy-monitoring, HNSCC patients showing an antibody decrease in the range of 30-100% lived disease free over a period of up to 26 months. The increase of antibodies from 2750 to 12,000 ng/ml mirrored recurrent disease. We can also show that the L1-capsidprotein is expressed in HPV16-DNA positive tumour-tissue. INTERPRETATION: HPV16-L1 DRH1 epitope-specific antibodies are linked to HPV16-induced malignant disease. As post-treatment biomarker, the assay allows independent post-therapy monitoring as well as early diagnosis of tumour recurrence. An AUC of 0.96 indicates high sensitivity and specificity for early detection of HPV16-induced disease. FUNDING: The manufacturer provided assays free of charge.

Sex-specific differences in patients with nonmelanoma skin cancer of the pinna.

BACKGROUND: Generally, it is known that men are affected more frequently by nonmelanoma skin cancer (NMSC) than women. The aim of our study was to investigate the effect of sex on the characteristics of NMSCs of the pinna at the population that our center serves and to compare it with the international data. METHODS: We analyzed retrospectively the data of 225 patients with NMSC of the pinna. Sex-specific differences were investigated for basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) subgroups. RESULTS: The ratio of BCC to cSCC was determined in male patients at 1:1.3, in contrast in females it was identified at 4:1 (P = .001). CONCLUSION: In our study, a new aspect of the sex-dependent distribution of cSCC and BCC of the pinna was demonstrated. Women are affected four times more frequently by BCC than by cSCC, whereas in men this ratio is approximately equal.

Concordance of tumor infiltrating lymphocytes, PD-L1 and p16 expression in small biopsies, resection and lymph node metastases of oropharyngeal squamous cell carcinoma.

OBJECTIVE: The incidence of oropharyngeal squamous cell carcinoma (OPSCC), especially human papillomavirus (HPV)-associated, is increasing worldwide. Immunotherapy become available for patients with carcinomas in the head and neck region, however without ideal biomarker. Markers like PD-L1 vary in the clone of the antibody used, and the method of evaluation. Adequate and reliable immune cells characterization and evaluation is still not found. Furthermore, studies analyzing representativeness of different tissue samples are scarce. We analyzed small biopsy, lymph node (LN) metastasis and resected OPSCC, in regards of tumor infiltrating lymphocyte (TIL) density, PD-L1 and p16 expression. MATERIAL AND METHODS: Patients with OPSCC diagnosed from 2000 to 2016, with small biopsy, resection specimen and LN metastasis samples were selected. We analyzed TILs on hematoxylin-eosin stain, and PD-L1 and p16 expression in tumor cells. Concordance between different tumor locations was evaluated. RESULTS: 93 patients, with 65 small biopsies, 72 resection specimens, and 70 LN metastases were included. TILs, p16 and PD-L1 demonstrated very high concordance. Additionally, PD-L1 expression in the small biopsies was more representative of the PD-L1 expression in the resection specimens, than the LN samples. CONCLUSION: TILs density can be reliably assessed using hematoxylin-eosin stain with high concordance between the small biopsy, resection specimen and LN metastasis. Evaluation of concordance of p16 expression is very high, nevertheless some cases might be misdiagnosed on a small biopsy or lymph node metastasis. Evaluation of PD-L1 expression is very reliable on the biopsy specimen. Different PD-L1 clones and methods of evaluation still remain to be addressed.

Head and neck cancer in Styria : An epidemiologic and clinical audit.

BACKGROUND: The outcome of patients with cancer of the head and neck is significantly improved by increased interdisciplinary cooperation. The main focus of this study was a comparison of epidemiologic factors (age, sex, origin, staging) of patients with head and neck cancer in Styria, with those for patients throughout Austria. METHODS: A retrospective data analysis of collected archived tumor board protocols of the Comprehensive Cancer Center (CCC) Graz included the patient's age, sex, area of residence, TNM stage, reasons for inoperability, comorbidities and performance status by ECOG (Eastern Cooperative Oncology Group), was performed. This study focuses on 340 patients who presented with a head and neck malignancy for the first time. RESULTS: In the period from January 2014 to December 2015 a total of 252 men (74.1%) and 88 women (25.9%) with malignant head and neck tumors, were presented in the tumor board for the first time. The mean age at diagnosis was 63.4 years. In 45.5% the patients already demonstrated advanced tumor stages (T4 = 27.9%, T3 = 17.6%). Most newly diagnosed neoplasms were cancers of the oropharynx (24.1%), larynx (19.4%) and oral cavity (18.8%) and 36.5% were considered to be inoperable. Curative and palliative treatments were initiated in 83.2% and 16.9%, respectively. CONCLUSION: The region of south Styria showed a higher incidence of T3 and T4 tumors of the oropharynx than the average Austrian population. Measures to increase awareness of this problem should be initiated to support general otorhinolaryngologists and general practitioners in detecting oropharyngeal cancers at an earlier stage.
