RESUMEN

BACKGROUND: The objective of this study was to identify how - and to what extent - overall symptom severity (OSS) score reflects individual chronic rhinosinusitis (CRS) symptoms and whether it can be measured using alternatives to the standard visual analog scale (VAS). METHODS: CRS patients from four sites across three continents rated their OSS scores, severities of nasal obstruction, nasal drainage, decreased sense of smell, facial pain/pressure and sleep disturbance using a standard VAS, VAS with labeled tick marks at every 1 centimeter, and by writing down their OSS on a scale of 0 - 100 (which was divided by 10), all of which lead to severity scores ranging from 0 - 10 in 0.1 intervals. Quality of life was measured using the SNOT-22 and EQ-5D VAS. RESULTS: In 311 CRS patients, OSS score was significantly correlated with SNOT-22 and EQ-5D VAS. OSS score was most greatly associated with the mean of all individual symptom severity scores. From individual CRS symptoms, OSS was most greatly associated with nasal obstruction followed by nasal drainage and facial pain/pressure severities. These results held true for participants with and without nasal polyps. Measurement of OSS and individual symptom severity scores using a standard VAS, tick-marked VAS, and write-in option had near-perfect consistency. CONCLUSIONS: We demonstrate for the first time that OSS largely reflects the mean of individual CRS symptom severities, although OSS is=== most weighted by nasal obstruction severity. OSS and individual symptom severity scores can be measured using a standard VAS, tick-marked VAS or write-in prompt with near-perfect consistency.

RESUMEN

PURPOSE: The RAS/MEK signaling pathway is essential in carcinogenesis and frequently altered in non-small-cell lung cancer (NSCLC), notably by KRAS mutations (KRASm) that affect 25%-30% of non-squamous NSCLC. This study aims to explore the impact of KRASm subtypes on disease phenotype and survival outcomes. PATIENTS AND METHODS: We conducted a retrospective analysis of the French Epidemiological Strategy and Medical Economics database for advanced or metastatic lung cancer from 2011 to 2021. Patient demographics, histology, KRASm status, treatment strategies, and outcomes were assessed. RESULTS: Of 10 177 assessable patients for KRAS status, 17.6% had KRAS p.G12C mutation, 22.6% had KRAS non-p.G12C mutation, and 59.8% were KRASwt. KRASm patients were more often smokers (96.3%) compared with KRASwt (85.8%). A higher proportion of programmed death-ligand 1 ≥50% was found for KRASm patients: 43.5% versus 38.0% (P < 0.01). KRASm correlated with poorer outcomes. First-line median progression-free survival was shorter in the KRASm than the KRASwt cohort: 4.0 months [95% confidence interval (CI) 3.7-4.3 months] versus 5.1 months (95% CI 4.8-5.3 months), P < 0.001. First-line overall survival was shorter for KRASm than KRASwt patients: 12.6 months (95% CI 11.6-13.6 months) versus 15.4 months (95% CI 14.6-16.2 months), P = 0.012. First-line chemoimmunotherapy offered better overall survival in KRAS p.G12C (48.8 months) compared with KRAS non-p.G12C (24.0 months) and KRASwt (22.5 months) patients. Second-line overall survival with immunotherapy was superior in the KRAS p.G12C subgroup: 12.6 months (95% CI 8.1-18.6 months) compared with 9.4 months (95% CI 8.0-11.4 months) for KRAS non-p.G12C and 9.6 months (8.4-11.0 months) for KRASwt patients. CONCLUSION: We highlighted distinct clinical profiles and survival outcomes according to KRASm subtypes. Notably KRAS p.G12C mutations may provide increased sensitivity to immunotherapy, suggesting potential therapeutic implications for sequencing or combination of therapies. Further research on the impact of emerging KRAS specific inhibitors are warranted in real-world cohorts.

RESUMEN

BACKGROUND: Patients with solid organ transplant (SOT) and solid tumors are usually excluded from clinical trials testing immune checkpoint blockers (ICB). As transplant rates are increasing, we aimed to evaluate ICB outcomes in this population, with a special focus on lung cancer. METHODS: We conducted a multicenter retrospective cohort study collecting real data of ICB use in patients with SOT and solid tumors. Clinical data and treatment outcomes were assessed by using retrospective medical chart reviews in every participating center. Study endpoints were: overall response rate (ORR), 6-month progression-free survival (PFS), and grade ≥3 immune-related adverse events. RESULTS: From August 2016 to October 2022, 31 patients with SOT (98% kidney) and solid tumors were identified (36.0% lung cancer, 19.4% melanoma, 13.0% genitourinary cancer, 6.5% gastrointestinal cancer). Programmed death-ligand 1 expression was positive in 29% of tumors. Median age was 61 years, 69% were males, and 71% received ICB as first-line treatment. In the whole cohort the ORR was 45.2%, with a 6-month PFS of 56.8%. In the lung cancer cohort, the ORR was 45.5%, with a 6-month PFS of 32.7%, and median overall survival of 4.6 months. The grade 3 immune-related adverse events rate leading to ICB discontinuation was 12.9%. Allograft rejection rate was 25.8%, and risk of rejection was similar regardless of the type of ICB strategy (monotherapy or combination, 28% versus 33%, P = 1.0) or response to ICB treatment. CONCLUSIONS: ICB could be considered a feasible option for SOT recipients with some advanced solid malignancies and no alternative therapeutic options. Due to the risk of allograft rejection, multidisciplinary teams should be involved before ICB therapy.

RESUMEN

BACKGROUND AND OBJECTIVE: The effectiveness of biologics in chronic rhinosinusitis with nasal polyps (CRSwNP) is well-established. However, real-world experience on the effectiveness of transitioning between two monoclonal antibodies is scarce. Therefore, we aimed to analyze the safety and efficacy of antibody switching in treatment of chronic rhinosinusitis. METHODS: All patients with CRSwNP or nonsteroidal anti-inflammatory drugs-exacerbated respiratory disease (N-ERD) requiring a switch between biologics were retrospectively studied. Analysis included changes in polyp size, quality of life parameters, asthma control, and side effects. RESULTS: Out of 195 patients treated with biologics for CRSwNP or N-ERD in our center, 23 (11.8%) required transition to a different monoclonal antibody. The majority switched from omalizumab to dupilumab (17/23, 73.9%), mostly due to inadequate symptom control. Nine out of these 17 patients (52.9%) were switched without a washout period. All patients showed significant improvement in nasal polyp score, asthma control test and sino-nasal outcome test-22 after changing to dupilumab. Keratoconjunctivitis sicca was the side-effect (4.3%) reported after the switch from omalizumab to dupilumab, which lead to termination of therapy in one patient. Due to limited sample size, other antibody transitions were reported in a descriptive manner. CONCLUSION: The transition to dupilumab is an effective option in patients with inadequate treatment response or side-effects of omalizumab in nasal polyposis. Our preliminary results indicate that a wash-out period may not be necessary when switching between biologics, however, these findings require further investigations. Other monoclonal antibody transitions also show promising results, but warrant validations in larger cohorts due to small patient samples in our study.

RESUMEN

Dysregulated hyperinflammatory response is key in the pathogenesis in patients with severe COVID-19 leading to acute respiratory distress syndrome and multiorgan failure. Whilst immunosuppression has been proven to be effective, potential biological targets and optimal timing of treatment are still conflicting. We sought to evaluate efficacy and safety of the Janus Kinase 1/2 inhibitor ruxolitinib, employing the previously developed COVID-19 Inflammation Score (CIS) in a prospective multicenter open label phase II trial (NCT04338958). Primary objective was reversal of hyperinflammation (CIS reduction of ≥25% at day 7 in ≥20% of patients). In 184 patients with a CIS of ≥10 (median 12) ruxolitinib was commenced at an initial dose of 10 mg twice daily and applied over a median of 14 days (range, 2-31). On day 7, median CIS declined to 6 (range, 1-13); 71% of patients (CI 64-77%) achieved a ≥25% CIS reduction accompanied by a reduction of markers of inflammation. Median cumulative dose was 272.5 mg/d. Treatment was well tolerated without any grade 3-5 adverse events related to ruxolitinib. Forty-four patients (23.9%) died, all without reported association to study drug. In conclusion, ruxolitinib proved to be safe and effective in a cohort of COVID-19 patients with defined hyperinflammation.

RESUMEN

BACKGROUND & AIMS: Nutrition education is not adequately represented in the medical curriculum, and this prompted the European Society for Clinical Nutrition and Metabolism (ESPEN) to launch the Nutrition Education in Medical Schools (NEMS) Project in 2017. The aim of this original paper was to describe the perspectives of different actors in the promotion of nutrition education in medical schools. METHODS: On 11 November 2021, an online meeting was held on this topic, where nine representatives from different backgrounds participated in the scientific programme. More than 640 participants registered to this webinar. RESULTS: The different models of Nutrition Education in Medical Schools were introduced by Prof. Cristina Cuerda (Spain) and Prof. Maurizio Muscaritoli (Italy). The students' perspective was given by Ms. Alexandra Archodoulakis (Germany) and Ms. Sila Gürbüz (Turkey), representing the European Medical Students' Association. The dietitian's perspective was given by Dr. Kirsten Berk (The Netherlands), whereas Dr. Matti Aapro (Switzerland) gave the medical doctor (oncology)'s perspective. Ms. Clare Farrand (Australia) gave the WHO perspective and Dr. Kristiina Patja (Finland) explained the healthy lifestyle teaching to medical students. Lastly, Prof. Michael Chourdakis (Greece) and Prof. Zeljko Krznaric (Croatia) hosted the round-table discussion. CONCLUSIONS: There was strong agreement among the representatives from different settings joining this ESPEN initiative that increasing nutritional knowledge and skills of young doctors is now possible and will launch a virtuous cycle that will proactively involve all the other healthcare professionals working in the nutritional field.

RESUMEN

Exercise could prevent physical and psychological deteriorations, especially during pandemic times of lock-down scenarios and social isolation. But to meet both, the common exercise protocols require optimization based on holistic investigations and with respect to underlying processes. This study aimed to explore individual chronic and acute effects of continuous and interval running exercise on physical and cognitive performance, mood, and affect and underlying neurophysiological factors during a terrestrial simulated space mission. Six volunteers (three females) were isolated for 120 days. Accompanying exercise training consisted of a continuous and interval running protocol in a cross-over design. Incremental stage tests on a treadmill were done frequently to test physical performance. Actigraphy was used to monitor physical activity level. Cognitive performance, mood (MoodMeter®), affect (PANAS), brain-derived neurotrophic factor (BDNF), insulin-like growth factor 1 (IGF-1), vascular-endothelial growth factor (VEGF), and saliva cortisol were investigated prior to, four times during, and after isolation, pre- and post-exercise on two separate days, respectively. As a chronic effect, physical performance increased (and IGF-1 tended) in the course of isolation and training until the end of isolation. Subjective mood and affect state, as well as cognitive performance, basal BDNF and VEGF levels, were well-preserved across the intervention. No acute effects of exercise were detected, besides slower reaction time after exercise in two out of nine cognitive tests, testing sensorimotor speed and memory of complex figures. Consistently higher basal IGF-1 concentrations and faster reaction time in the psychomotor vigilance test were found for the continuous compared to the interval running protocol. The results suggest that 120 days of isolation and confinement can be undergone without cognitive and mental deteriorations. Regular, individual aerobic running training supporting physical fitness is hypothesized to play an important role in this regard. Continuous running exercise seems to trigger higher IGF-1 levels and vigilance compared to interval running. Systematic and prolonged investigations and larger sample size are required to follow up on exercise-protocol specific differences in order to optimize the exercise intervention for long-term psycho-physiological health and well-being.

RESUMEN

Cutaneous squamous cell carcinoma (CSCC) is the most frequent post-transplant tumour entity resulting from immunosuppression treatment that is needed to prevent organ rejection. Solid organ transplant (SOT) recipients are at higher risk for CSCC and vulnerable for aggressive disease or a fatal course. Here, we report on a case of post-kidney transplant metastatic CSCC, demonstrating efficacy of cemiplimab in achieving complete remission after previous disease progression under cetuximab treatment. Unfortunately, the patient developed severe pneumonia, which was only later diagnosed as cemiplimab-associated pneumonitis. Due to a rapidly evolving septic condition, intensive care treatment was required and resulted in a fatal outcome. The patient's transplant remained intact, yet first-line treatment of advanced CSCC, such as with cemiplimab, should be weighed critically in SOT recipients, as transplant rejection may occur. However, the present case underlines the feasibility of cemiplimab as a second-line treatment option in this patient collective.

RESUMEN

Optoacoustic imaging (OAB) has developed steadily in recent years. By means of partly pulsed light, in a wide variety of wavelengths, different colour carriers (chromophores) are excited to form sound waves. These in turn are detected by the newly developed systems and converted into three-dimensional images by means of various algorithms. The technique is characterised by a good ratio between contrast and penetration depth and can create macro-, meso- and microscopic images due to its scalability. Optoacoustic macroscopy broadly irradiates the area to be examined with laser light. This can produce images with a high penetration depth, but only with a moderate resolution. Clinically interesting fields of application are for example the results of sentinel lymph nodes (SLNs) examined ex vivo using macroscopic optoacoustics. Due to the ability of OAB to visualise melanin, the detection rate of metastases was superior to previous methods, but not to histology. The ability to visualise dermal and epidermal structures, especially vessels, with good resolution makes optoacoustic mesoscopy useful in the examination of inflammatory skin diseases and could contribute to the verification of the success of therapy, e.g., with biologics for psoriasis vulgaris or atopic eczema (AE), in the future. Optoacoustic microscopy, which has so far been limited mainly to preclinical in vivo research, could be used in the future to detect even finer vascular structures and their changes. The clinical possibilities of OAB seem to be of great benefit and continue to be the subject of intensive research.

RESUMEN

Background and Aim: "Social norms" (SN)-interventions are aimed at changing existing misperceptions regarding peer substance use by providing feedback on actual norms, thereby affecting personal substance use. It is unknown whether SN-intervention effects previously demonstrated in US students can be replicated in German students. The aim of the INSIST-study was to examine the effects of a web-based SN-intervention on substance use. Design: Cluster-controlled trial. Setting: Eight Universities in Germany. Participants and Measurements: Students were recruited at four intervention vs. four delayed intervention control Universities. 4,463 students completed baseline, 1,255 students (59% female) completed both baseline and 5-months follow-up web-based surveys on personal and perceived peer substance use. Intervention participants received feedback contrasting personal and perceived peer use with previously assessed use and perceptions of same-sex, same-university peers. Intervention effects were assessed via multivariable mixed logistic regression models. Findings: Relative to controls, reception of SN-feedback was associated with higher odds for decreased alcohol use (OR: 1.91, 95% CI 1.42-2.56). This effect was most pronounced in students overestimating peer use at baseline and under or accurately estimating it at follow-up (OR: 6.28, 95% CI 2.00-19.8). The OR was 1.33 (95% CI 0.67-2.65) for decreased cannabis use in students at intervention Universities and was statistically significant at 1.70 (95% CI 1.13-2.55) when contrasting unchanged and decreased with increased use. Regarding tobacco use and episodes of drunkenness, no intervention effects were found. Conclusions: This study was the first cluster-controlled trial suggesting beneficial effects of web-based SN-intervention on alcohol and cannabis use in a large sample of German University students. Clinical Trial Registration: The trial registration number of the INSIST-study is DRKS00007635 at the "German Clinical Trials Register."

RESUMEN

RATIONALE: Cystic fibrosis (CF), caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, leads to impaired pancreatic function and therefore reduced intestinal absorption of lipids and fat-soluble vitamins especially in patients with CF developing pancreatic insufficiency (PI). Previous studies showed that CFTR modulator therapy with lumacaftor-ivacaftor (LUM/IVA) in Phe508del-homozygous patients with CF results in improvement of pulmonary disease and thriving. However, the effects of LUM/IVA on plasma concentration of the lipid soluble vitamins A and E remain unknown. OBJECTIVES: To investigate the course of plasma vitamin A and E in patients with CF under LUM/IVA therapy. METHODS: Data from annual follow-up examinations of patients with CF were obtained to assess clinical outcomes including pulmonary function status, body mass index (BMI), and clinical chemistry as well as fat-soluble vitamins in Phe508del-homozygous CF patients before initiation and during LUM/IVA therapy. RESULTS: Patients with CF receiving LUM/IVA improved substantially, including improvement in pulmonary inflammation, associated with a decrease in blood immunoglobulin G (IgG) from 9.4 to 8.2 g/L after two years (p < 0.001). During the same time, plasma vitamin A increased significantly from 1.2 to 1.6 µmol/L (p < 0.05), however, levels above the upper limit of normal were not detected in any of the patients. In contrast, plasma vitamin E as vitamin E/cholesterol ratio decreased moderately over the same time from 6.2 to 5.5 µmol/L (p < 0.01). CONCLUSIONS: CFTR modulator therapy with LUM/IVA alters concentrations of vitamins A and vitamin E in plasma. The increase of vitamin A must be monitored critically to avoid hypervitaminosis A in patients with CF.

RESUMEN

BACKGROUND: Bladder cancer cells orchestrate tumour progression by pro-inflammatory cytokines. Cytokines modulate the local tumour microenvironment and increase the susceptibility of tumour distant tissues for metastasis. Here, we investigated the impact of human bladder cancer cell derived factors on the ability to modulate and activate human vascular endothelial cells. METHODS: The pro-inflammatory and pro-coagulatory potential of four different bladder cancer cell lines was accessed by qRT-PCR arrays and ELISA. Modulation and activation of endothelial cells was studied in microfluidic devices. Clinical relevance of our findings was confirmed by immune histology in tissue samples of bladder cancer patients and public transcriptome data. RESULTS: The unbalanced ratio between interleukin (IL)-1 and IL-1 receptor antagonist (IL-1ra) in the secretome of bladder cancer cells converted the quiescent vascular endothelium into a pro-adhesive, pro-inflammatory, and pro-coagulatory surface. Microfluidic experiments showed that tumour cell induced endothelial cell activation promoted leukocyte recruitment and platelet adhesion. Human bladder cancer tissue analysis confirmed that loss of IL-1ra and elevated IL-1 expression was associated with enhanced cancer progression. CONCLUSIONS: Our data indicate that IL-1 and IL-1ra were dysregulated in bladder cancer and could facilitate tumour dissemination through endothelial cell activation. Targeting the IL-1/IL-1ra axis might attenuate tumour-mediated inflammation and metastasis formation.

RESUMEN

BACKGROUND: Keratinocyte carcinoma (KC) is an increasingly important public health problem with an especially high prevalence in outdoor workers. In contrast to other occupations, foresters spend most of their outdoor time under the shade of trees. OBJECTIVES: We aimed to compare the unique sun exposure patterns and sun protection behaviour of foresters with those of other outdoor workers and their relation to the KC risk. METHODS: In July 2018, a cross-sectional study was conducted at an international forestry fair using a questionnaire about health awareness and skin cancer screening by dermatologists to assess the prevalence of KC. RESULTS: A total of 591 participants (78.7% male; mean age 46.8 ± 16.2 years) including 193 foresters were enrolled. Of all foresters, 72% experienced sunburns (solar erythema) within the past year and 50% of them experienced the worst sunburn during work. Foresters were most likely to often/always wear protective clothes (29.0%) but were least likely to often/always avoid midday sun (23.8%) and stay in the shade (31.1%). Having an outdoor profession or spending hours outside for leisure was negatively associated with sun protection. Skin examination revealed an overall KC prevalence of 16.7%, with 16.5% of foresters being affected. CONCLUSION: Despite being protected by trees, the risk of KC for foresters is comparable to that of other professional groups. Shade alone may not provide sufficient protection. Additional sun protection measures are necessary.

RESUMEN

BACKGROUND: Sarcopenia is a muscle disease defined by a loss of muscle strength associated to a decrease in skeletal muscle mass. In addition to aging, many factors may contribute to sarcopenia as cancer and/or androgen deprivation therapy (ADT). OBJECTIVES: The aims of this study are to describe the prevalence of sarcopenia in older prostate cancer patients before initiation of treatment with ADT and radiotherapy, and to evaluate the impact of ADT on the occurrence or aggravation of sarcopenia in this population. DESIGN: longitudinal study. PARTICIPANTS AND SETTING: Sarcopenia was prospectively evaluated in 31 consecutive patients aged 70 to 88 years, referred in one hospital unit of south eastern France, for a comprehensive geriatric assessment (CGA) before cancer treatment initiation. MEASUREMENTS AND RESULTS: CGA, measures of muscle strength and physical performances were performed at baseline (T0) and at the end of cancer treatment (T1). Appendicular skeletal muscle mass was measured by Dual-energy X-ray absorptiometry (DXA) at the end of treatment. At T0, 8 patients (among 31) had a probable sarcopenia according to European consensus, and 18 had altered physical performance. At T1, 15 patients (among 19) had abnormal one leg balance test. Finally, only one patient had a sarcopenia confirmed by DXA. CONCLUSION: This preliminary study showed a high prevalence of muscle disorders before initiation of ADT in a population of elderly cancer prostate patients with intermediate frailty status, and an increased risk of falls at the end of ADT. This highlighted the importance of screening for sarcopenia before treatment initiation, to prevent the occurrence or aggravation of sarcopenia by possible adjustment of treatment, and implementation of appropriate exercise and nutrition interventions.

RESUMEN

BACKGROUND & AIMS: Teduglutide, a GLP-2-analog, has proven effective in two placebo-controlled studies in reducing parenteral support (PS) in patients with short bowel syndrome-associated intestinal failure (SBS-IF) after 24 weeks. The aim of this study was to describe in a real-life situation the effects of teduglutide treatment and their predictive factors. METHODS: We included 54 consecutive SBS-IF patients treated with teduglutide in France for at least 6 months from 10 expert centers. Small bowel length was 62 ± 6 cm and 65% had colon in continuity. PS was 4.4 ±0 .2 infusions per week, started 9.8 ± 1.2 years before. Response (PS reduction ≥ 20%) and PS discontinuation rates were assessed at week 24. Adjusted p values of factors associated with response and weaning were calculated using a multivariate logistic regression model. RESULTS: At week 24, 85% of patients were responders and 24% had been weaned off PS, with a 51% reduction of PS needs and 1.5 ± 0.2 days off PS per week. Response to teduglutide was influenced by a higher baseline oral intake (p = 0.02). Weaning off PS was influenced by the presence of colon (p = 0.04), a lower PS volume (p = 0.03) and a higher oral intake (p = 0.01). There were no differences based on age, bowel length or SBS-IF causes. CONCLUSIONS: Our study confirms the effectiveness of teduglutide in reducing PS needs in SBS-IF patients. We associated reduced parenteral support volume with baseline parenteral volume support, bowel anatomy, and oral intake. These findings underline the role of nutritional optimization when starting the treatment.

RESUMEN

Older adults are at high risk of developing cardiovascular disease (CVD). Pre-clinical studies indicate that resveratrol (RSV), a polyphenol commonly found in grapes and red wine, may help prevent development of CVD. Based on our previous reports where the 300 mg and 1000 mg doses appeared safe and improved psychomotor function in a dose-dependent manner, our hypothesis was that RSV would reduce biomarkers of CVD risk in overweight, but otherwise healthy older adults and that 1000 mg would lower CVD biomarkers >300 mg. This analysis was performed on samples from older participants (65 years and older) who were randomized to a 90 day RSV treatment with 300 mg (n = 10), 1000 mg (n = 9) or placebo (n = 10). We measured levels of CVD risk biomarkers i.e. oxidized low-density lipoprotein (oxLDL), soluble E-selectin-1 (sE-selectin), soluble Intercellular Adhesion Molecule-1 (sICAM-1), Soluble Vascular Cell Adhesion Molecule-1 (sVCAM-1), total plasminogen activator inhibitor (tPAI-1). Statistical significance was set at p < 0.05. Both sVCAM-1 and tPAI increased significantly more in the 1000 mg vs. 300 mg and placebo groups. Other biomarkers (300 mg vs. 1000 mg vs. placebo: oxLDL, sEselectin-1 and sICAM-1) followed the same trend toward higher levels in the 1000 mg group compared to the 300 mg and placebo groups, without reaching statistical significance. This pilot project suggests that a higher dose of RSV may increase the levels of CVD risk biomarkers in overweight older adults. Given no change in the CVD risk biomarkers in response to a lower dose, future studies should test the effects of different doses of RSV to evaluate potential detrimental effects of higher doses on CVD biomarkers and measures of cardiovascular function in older adults at risk for CVD.

RESUMEN

PURPOSE: The "Enhanced recovery after surgery" (ERAS) concept has been continuously developed for many surgical disciplines. Shorter length of stay (LOS) and associated cost savings have been achieved without an increase in the complication or readmission rate. Current guidelines helped to support an increasing standardisation of care. One innovation of the recently published update is the proposal to integrate prehabilitation (PREHAB) into the ERAS concept. On this basis, the authors provide an overview of the current data on ERAS concepts in gynecological oncology and review the evidence of prehabilitation concepts. METHODS: Systematic literature review of all comparative studies on ERAS concepts in gynecological oncology and prehabilitation undergoing abdominal cancer surgery was performed using the standard databases. Outcomes of interest included prehabilitation program composition (exercise, nutritional, and psychological interventions), duration and outcome measures used to determine impact of prehabilitation vs. standard care. RESULTS: Five studies reported on PREHAB programs in gynecology (three RCTs, one study protocol, one pilot study). There is no trial evaluating a pathway for patients with extensive ovarian or cervical cancer. Study protocols were heterogenous, but showed improvements in both physical and psychological parameters. ERAS protocols in ovarian cancer patients were investigated in 12 observational studies, mostly single center and only 1 RCT, in 4 studies patients with ovarian cancer or patients. Most studies showed improvement in complication rate and shorter LOS. DISCUSSION: PREHAB programs seem feasible in abdominal cancer surgery and may improve surgical outcome. However, there is no prospective trial in gynecological oncology so far. Furthermore, there is no concept combining ERAS and PREHAB interventions. Therefore, the authors encourage the further development of both by describing in a novel treatment algorithm.

RESUMEN

BACKGROUND: The use of sunscreen can reduce the risk of UV-induced skin lesions. Health authorities have provided recommendations for the correct use of sunscreen use: Sufficient amount of sunscreen should be applied at least 30 min before the sun exposure and should be reapplied every 2 h. OBJECTIVE: We aimed to research the practice of sunscreen use in a population-based and representative sample in Germany. METHODS: For this cross-sectional survey, 3000 German residents aged 14-45 years were surveyed in standardized telephone interviews in 2018. Survey participants provided data on the frequency of sunscreen use in summer, timing of (re-)application and their skin characteristics. The data were weighted by age, sex, educational level and federal state to ensure the national representativeness of the sample. RESULTS: Overall, 79.4% of respondents used sunscreen always, often or sometimes when being exposed to the sun. However, 87.2% of sunscreen users did not follow the recommendations on timing of application, 59.5% did not comply with the timing of reapplication. We also saw, that people potentially used too little sunscreen. These data did not differ noticeably by skin types of participants. CONCLUSION: Our study revealed deficits in use of sunscreen in Germany, indicating that people here pay little attention to the recommendations of health authorities, regardless of their skin type. There is therefore an urgent need for targeted public information on this issue. Improving public knowledge on correct sunscreen use through educational campaigns or individual counselling by health professionals could be a first step.
