We present a 43-year old female patient, admitted to the intensive care unit, recovering from a Bentall procedure because of a supra-coronary aneurysm and unicuspid aortic valve. Few hours following surgery,a marked lactic acidosis, hypoxemia and increased central venous pressure developed. Pulmonary angio-CT was performed to exclude pulmonary embolism. Because of severe peripheral vasoconstriction, iodine contrast could only be administered through a narrow lumen central venous catheter, which limited the maximum flow rate to 1.5 ml/s. Images were performed with triggering in the pulmonary trunk. Review of the images showed no evidence for pulmonary embolism. Despite the low flow rate, a clear enhancement of the pulmonary artery was observed (up to 460 HU) (Fig. 1). Such an enhancement of the pulmonary artery is normally only achieved when injecting contrast at a flow rate of 4-5 ml/s. These perfect images, obtained at a low contrast flow rate in fact indicate severely impaired right ventricular function.

Intstines ,perforation ,Medical physics. Medical radiology. Nuclear medicine ,R895-920 - Abstract
Patients on glucocorticosteroid therapy are at increased risk of gastrointestinal perforation. The associated morbidity and mortality of perforations in this group is increased, compared with normal groups. This difference is due to the delay between onset of clinical symptoms and treatment. In the presence of steroids, gastrointestinal perforation is more difficult to diagnose clinically because signs and symptoms of perforation are masked by the anti-inflammatory effect of the steroids.

- Abstract
Background: Numerous strategies for preventing abusive head trauma (AHT) have been proposed, but controlled studies failed to demonstrate their effectiveness. Digital tools may improve the effectiveness of AHT prevention strategies by reaching a large proportion of the adult population., Objective: This study aimed to describe the characteristics of videos of AHT prevention published on the internet, including their quality content, and to study their association with popularity., Methods: From a systematic appraisal performed in June 2023, we identified videos addressing the primary prevention of AHT in children younger than 2 years that were published in English or French on the internet by public organizations or mainstream associations. We analyzed the characteristics of the videos; their quality with the Global Quality Scale (GQS); and their association with an index of popularity, the Video Power Index, using multivariable quasi-Poisson modeling., Results: We included 53 (6.6%) of the 804 videos identified. Videos were mainly published by public organizations (43/53, 81%). The median time spent on the web was 6 (IQR 3-9) years, the median length was 202 (IQR 94-333) seconds, and the median GQS score was 4 (IQR 3-4). Infants were often depicted (42/53, 79%), including while crying (35/53, 66%) and being shaken (21/53, 40%). The characterization of shaking as an abuse and its legal consequences were cited in 47% (25/53) and 4% (2/53) of videos, respectively. The main prevention strategies in the videos were to raise awareness of the noxious outcome of shaking (49/53, 93%) and convince viewers of the effectiveness of coping strategies for infants' cries (45/53, 85%). The Video Power Index was positively correlated with the GQS (r=0.38; P=.007) and was independently associated with depicting an infant being shaken (P=.03; β=1.74, 95% CI 1.06-2.85) and the use of text or headers (P=.04; β=2.15, 95% CI 1.08-4.26)., Conclusions: AHT prevention videos had high quality but did not frequently deal with parental risk factors. The characteristics identified as being associated with the popularity of AHT prevention videos could help improve the impact of future prevention programs by enhancing their popularity., (©Luc Goethals, Victoria Prokofieva Nelson, Fabien Fenouillet, Karine Chevreul, Manon Bergerat, Christine Lebreton, Yacine Refes, Flora Blangis, Martin Chalumeau, Enora Le Roux.

- Abstract
In mouse models of myasthenia gravis (MG), anti-acetylcholine receptor (AChR) antibodies can be quantified to monitor disease progression and treatment response. In mice, enzyme-linked immunosorbent assay (ELISA) is the gold standard to quantify these antibodies. However, this method requires antigen purification, which is both time-consuming and expensive. In humans, radioimmunoassay (RIA)-which is more sensitive than ELISA-is commonly used to quantify AChR antibodies. At present, however, no commercial RIA kits are available to quantify these antibodies in mice. The aim of this study was to compare a modified commercial human RIA kit to two ELISA methods to detect AChR antibodies in an experimental autoimmune mouse model of MG (EAMG). C57BL/6 J mice were immunized with purified AChR from Tetronarce californica (T-AChR). Serum samples were analyzed by RIA and two ELISAs (T-AChR and purified mouse AChR peptide [m-AChR]). The modified RIA showed excellent sensitivity (84.1 %) and specificity (100 %) for the detection of AChR antibodies. RIA showed a good agreement with T-AChR ELISA (κ = 0.69) but only moderate agreement with m-AChR ELISA (κ = 0.49). These results demonstrate the feasibility of modifying a commercially-available RIA kit to quantify AChR antibodies in EAMG. The advantage of this technique is that it eliminates the need to develop the entire methodology in-house and reduces inter and intra-laboratory variability., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier B.V.

- Abstract
Objectives: Chlamydia Trachomatis (CT) is the most sexually transmitted infection in France. This study aimed to assess the feasibility of systematic screening for CT among people attending a preventive health examination in Health Examination Centres (HECs) and to compare positive CT cases according to deprivation., Design: A cross-sectional multicentre study in thirteen HECs in France in January 2018., Methods: Self-sampling CT screening was proposed among 18-25 years women and 18-30 years men, who were sexually active and without recent CT treatment. Related data and referred specimens were collected among attendees for the study, including deprivation and health status. CT positivity was estimated by genders. We explored association between CT infection and deprivation by univariate and multivariate modelling., Results: The CT screening was proposed to 1701 eligible young people. 90.1 % [88.6-91.5] accepted and participated with 43.6 % being women, 54.3 % being deprived people. 75.4 % [72.1-78.6] screened women performed self-taken vaginal swabs and others took urinary tests. Screening was conducted in 1486 people. Overall prevalence of CT infection was 4.7 % [3.7%-5.9 %], significantly higher for women than men (6.4 % vs 3.4 %, p=0.009 ). Among women, being deprived increased the likelihood of CT positivity (aOR 4.95; 95 % CI 2.02 to 12.00) more than it did for men., Conclusions: Individual deprivation was significantly associated with having a CT infection among women. The feasibility of CT screening in HECs was demonstrated, with a high acceptance, and led to the implementation of CT screening in all HECs. Promoting access to CT screening to deprived population might contribute to reduce social inequalities in health., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

- Abstract
Although radiotherapy continues to evolve as a mainstay of the oncological armamentarium, research and innovation in radiotherapy in low-income and middle-income countries (LMICs) faces challenges. This third Series paper examines the current state of LMIC radiotherapy research and provides new data from a 2022 survey undertaken by the International Atomic Energy Agency and new data on funding. In the context of LMIC-related challenges and impediments, we explore several developments and advances-such as deep phenotyping, real-time targeting, and artificial intelligence-to flag specific opportunities with applicability and relevance for resource-constrained settings. Given the pressing nature of cancer in LMICs, we also highlight some best practices and address the broader need to develop the research workforce of the future. This Series paper thereby serves as a resource for radiation professionals., Competing Interests: Declaration of interests RK reports receiving support from the University of Utah Huntsman Cancer Institute for attending meetings and for travel.

- Abstract
Studies on the bioavailability, serum levels, and absorption of hydrolyzable tannin compounds are lacking. In this study, we performed a pharmacokinetic trial, measured the serum levels of compounds in broilers that were reared with different feed added or not with tannins, and tested the digestibility of tannins throughout the intestinal tract. Only gallic acid and 4- O -methyl gallic acid were found in the serum. Moreover, gallic acid showed a 41.8% absolute oral bioavailability and a 72.3% relative bioavailability of gallic acid from chestnut extract compared to the standard. The rapid metabolization caused alternating serum levels during the day and night. These patterns were not affected by the feed type or the previous addition of tannins in the feed. The absorption and metabolization in the intestines occurred gradually throughout the intestinal tract. The latter was true for gallic acid as well as ellagic acid, which was not found in the serum. We can conclude that components from chestnut tannins are absorbed throughout all components of the intestinal tract and are eliminated quickly with little interaction from the feed and previous addition of tannins. Moreover, ellagic acid seems to be absorbed but would remain accumulated in the intestinal tissue or be metabolized by the microbiome.

- Abstract
Human epidermal growth factor receptor 2 (HER2) status is used for decision-making in breast carcinoma treatment. The status is obtained through immunohistochemistry or in situ hybridization. These two methods have the disadvantage of necessitating tissue sampling, which is prone to error due to tumor heterogeneity or interobserver variability. Whole-body imaging might be a solution to map HER2 expression throughout the body. Methods: Twenty patients with locally advanced or metastatic breast carcinoma (5 HER2-positive and 15 HER2-negative patients) were included in this phase II trial to assess the repeatability of uptake quantification and the extended safety of the [
68 Ga]Ga-NOTA-anti-HER2 single-domain antibody (sdAb). The tracer was injected, followed by a PET/CT scan at 90 min. Within 8 d, the procedure was repeated. Blood samples were taken for antidrug antibody (ADA) assessment and liquid biopsies. On available tissues, immunohistochemistry, in situ hybridization, and mass spectrometry were performed to determine the correlation of HER2 status with uptake values measured on PET. If relevant preexisting [18 F]FDG PET/CT images were available (performed as standard of care), a comparison was made. Results: With a repeatability coefficient of 21.8%, this imaging technique was repeatable. No clear correlation between PET/CT uptake values and pathology could be established, as even patients with low levels of HER2 expression showed moderate to high uptake. Comparison with [18 F]FDG PET/CT in 16 patients demonstrated that in 7 patients, [68 Ga]Ga-NOTA-anti-HER2 shows interlesional heterogeneity within the same patient, and [18 F]FDG uptake did not show the same heterogeneous uptake in all patients. In some patients, the extent of disease was clearer with the [68 Ga]Ga-NOTA-anti-HER2-sdAb. Sixteen adverse events were reported but all without a clear relationship to the tracer. Three patients with preexisting ADAs did not show adverse reactions. No new ADAs developed. Conclusion: [68 Ga]Ga-NOTA-anti-HER2-sdAb PET/CT imaging shows similar repeatability to [18 F]FDG. It is safe for clinical use. There is tracer uptake in cancer lesions, even in patients previously determined to be HER2-low or -negative. The tracer shows potential in the assessment of interlesional heterogeneity of HER2 expression. In a subset of patients, [68 Ga]Ga-NOTA-anti-HER2-sdAb uptake was seen in lesions with no or low [18 F]FDG uptake. These findings support further clinical development of [68 Ga]Ga-NOTA-anti-HER2-sdAb as a PET/CT tracer in breast cancer patients., (© 2024 by the Society of Nuclear Medicine and Molecular Imaging.)- Published

- Abstract
The Cyberball is the most commonly employed paradigm for the investigation of the effects of social exclusion, also called ostracism. The analysis of event-related potentials (ERPs), short-term stimulus-induced fluctuations in the EEG signal, has been employed for the identification of time-sensitive neural responses to ostracism-related information. Changes in ERPs during the Cyberball are normally attributed to the effect of ostracism, but it has been argued that characteristics of the paradigm, not ostracism, are the driving force for these changes. To elucidate the origin of the ERP changes in the Cyberball, we systematically reviewed the Cyberball-ERP literature of healthy, adult populations, and evaluated whether the social context of ostracism or characteristics of the paradigm are better suited for the explanation of the found results. Our results show that for many components no clear origin can be identified, but that expectancy violations, not ostracism, best explains the results of the P3 complex. Future research should therefore also employ other paradigms for the research into the effects of ostracism on ERPs., Competing Interests: Conflict of interest The authors declare no conflict of interest., (Copyright © 2023 Elsevier Ltd.

- Abstract
Background: The Emergency unit of the hospital (Department) (ED) is the fastest and most common way for most French general practitioners (GPs) to respond to the complexity of managing older adults patients with multiple chronic diseases. In 2013, French regional health authorities proposed to set up telephone hotlines to promote interactions between GP clinics and hospitals. The main objective of our study was to analyze whether the hotlines and solutions proposed by the responding geriatrician reduced the number of hospital admissions, and more specifically the number of emergency room admissions., Methods: We conducted a multicenter observational study from April 2018 to April 2020 at seven French investigative sites. A questionnaire was completed by all hotline physicians after each call., Results: The study population consisted of 4,137 individuals who met the inclusion and exclusion criteria. Of the 4,137 phone calls received by the participants, 64.2% (n = 2 657) were requests for advice, and 35.8% (n = 1,480) were requests for emergency hospitalization. Of the 1,480 phone calls for emergency hospitalization, 285 calls resulted in hospital admission in the emergency room (19.3%), and 658 calls in the geriatric short stay (44.5%). Of the 2,657 calls for advice/consultation/delayed hospitalization, 9.7% were also duplicated by emergency hospital admission., Conclusion: This study revealed the value of hotlines in guiding the care of older adults. The results showed the potential effectiveness of hotlines in preventing unnecessary hospital admissions or in identifying cases requiring hospital admission in the emergency room. Hotlines can help improve the care pathway for older adults and pave the way for future progress., Trial Registration: Registered under Clinical Trial Number NCT03959475.

- Abstract
Purpose: Sufficient radiotherapy (RT) capacity is essential to delivery of high-quality cancer care. However, despite sufficient capacity, universal access is not always possible in high-income countries because of factors beyond the commonly used parameter of machines per million people. This study assesses the barriers to RT in a high-income country and how these affect cancer mortality., Methods: This cross-sectional study used US county-level data obtained from Center for Disease Control and Prevention and the International Atomic Energy Agency Directory of Radiotherapy Centres. RT facilities in the United States were mapped using Geographic Information Systems software. Univariate analysis was used to identify whether distance to a RT center or various socioeconomic factors were predictive of all-cancer mortality-to-incidence ratio (MIR). Significant variables ( P ≤ .05) on univariate analysis were included in a step-wise backward elimination method of multiple regression analysis., Results: Thirty-one percent of US counties have at least one RT facility and 8.3% have five or more. The median linear distance from a county's centroid to the nearest RT center was 36 km, and the median county all-cancer MIR was 0.37. The amount of RT centers, linear accelerators, and brachytherapy units per 1 million people were associated with all-cancer MIR ( P < .05). Greater distance to RT facilities, lower county population, lower average income per county, and higher proportion of patients without health insurance were associated with increased all-cancer MIR ( R -squared, 0.2113; F , 94.22; P < .001)., Conclusion: This analysis used unique high-quality data sets to identify significant barriers to RT access that correspond to higher cancer mortality at the county level. Geographic access, personal income, and insurance status all contribute to these concerning disparities. Efforts to address these barriers are needed.

- Abstract
The quantification of hydrolysable polyphenols such as gallic, ellagic acid and vescalagin by HPLC-DAD is classically run after methanol extraction as a reference solvent. Water extraction is usually discarded because of a lower obtention of total polyphenol content compared to methanol extraction. In our study, methanol was compared to water extraction in both the total polyphenol content method and the HPLC-DAD analysis. Total polyphenol content in water extraction was lower than in methanol extraction, but water extraction gave better results on HPLC-DAD. In conclusion, total polyphenol content cannot be used as reference to choose the solvent of extraction to quantify some polyphenols by HPLC-DAD because of the specific properties of each polyphenol. Indeed, recovery results obtained on hydrolysable polyphenols with water extraction were better and with a lower variability than following methanol extraction., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 Published by Elsevier Ltd.)

- Abstract
Since 2019, EU limits apply to cadmium (Cd) concentrations in cacao-derived food products. The dietary risk assessment leading to that regulation used consumption surveys aggregated to a limited number of chocolate product categories and did not consider differences in Cd bioaccessibility. Here, the cacao-related dietary Cd exposure in the Belgian population was estimated with higher resolution and accounting for bioaccessibility. A food frequency questionnaire and a 24-h recall (N = 2055) were set up for the Belgian population, in combination with ICP-MS analysis of a large subset of cacao-containing products (N = 349). Both the average chocolate consumption (28 g day
-1 ) and the relative contribution of chocolate to the total dietary Cd exposure (7-9%) were higher than previously estimated for the Belgian population, probably because of some selection bias towards chocolate consumers in the cohort. The Cd bioaccessibility in chocolate products was a factor 5 (cacao powder) and 2 (dark chocolate) lower compared to wheat flour, suggesting lower bioavailability in chocolate than in wheat, which is a main contributor to dietary Cd. This study suggests that Cd intake from cacao consumption has been underestimated because of hidden cacao in non-chocolate food categories but, in contrast, may have overestimated the true exposure because of lower bioavailability compared to the main foodstuffs contributing to Cd exposure., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

- Abstract
Amyloidoisis in patients with Waldenström macroglobulinemia (WM) mostly involves the heart, peripheral nerves and kidneys. Retroperitoneal amyloidosis is a rare finding. We describe a 62-year-old man with an incidental finding of a monoclonal gammopathy and elevated inflammatory parameters. Bilateral moderately active retroperitoneal infiltration with punctiform calcifications was found on fluorine-18-fluorodeoxyglucose (
18 F-FDG) positron emission tomography/computed tomography (PET/CT) imaging. Taken together, these findings are suggestive of Waldenström associated amyloidosis. Computed tomography-guided retroperitoneal biopsy confirmed the diagnosis.- Published

- Abstract
Rationale: The ARS finance geriatric hotlines in order to improve the articulation between town medicine and the hospital. The objective of our study is to describe the health status and the care pathway of subjects aged over 75 years hospitalised in a geriatric short stay hospital via a geriatric hotline., Materials and Methods: This prospective multicentre study included 1,451 subjects over 24 months. The primary endpoint was the average length of stay. The secondary endpoints were medico-socio-demographic data., Results: The population hospitalised via a hotline is comparable to that usually found in geriatric short stay services. The length of stay is correlated with the lifestyle and the mode of discharge (p < 0.001). There was a significant excess risk of non-return to the previous place of residence according to age, average length of stay, comorbidities and degree of dependence., Conclusion: The care pathway for elderly people over 75 years old hospitalised through the hotline is optimised, with an average length of stay of 14 days, demonstrating a good link between town medicine and hospital. This approach allows for the early management of elderly subjects in the geriatric care system.

- Abstract
It is known that high doses of various tannins could impair broiler growth, and this seems to be linked to a lowered protein availability. However, effects on protein digestion under the influence of hydrolysable tannins were minimal in previous research and literature. Other possible proposed reasons to explain reduced growth are scarce. In this experiment we studied the effect of hydrolysable tannins on body allometry by using different feeding schemes throughout the rearing period. In total 112 individually reared male Ross 308 broilers received a 3-phase basal diet with chestnut wood extract (+: 2,000 mg/kg) or not (-: 0 mg/kg) (Tanno-SAN
® , Sanluc International NV, Belgium). This resulted in 2 groups during the starter period (S+, S-), 4 groups in the grower period (G++, G+-, G-+, G-) and 8 groups in the finisher period (F+++, F++-, F+-+, F+--, F-++, F-+-, F--+, F--). Similar to previous studies, growth reduction was also observed in this study. Effects were the largest in broilers that were given the tannins during the grower phase. At the end of each phase 8 broilers per group were euthanized and sampled. Liver, pancreas, pectoralis muscle, intestinal weights and intestinal length were recorded. The largest effects were seen on the intestine. Broilers that received tannins during the grower phase, had longer intestines at the end of the finisher period. Furthermore, histological differences between treatment groups were observed at the end of the grower period. Addition of tannins in the grower phase (G-+, G++) resulted in longer villi, whereas addition of tannins in the starter (G+-, G++) caused deeper crypts at the end of the grower phase, with the group (G-+) having the highest villi-to-crypt ratio. These results tentatively prove that tannins influence intestinal growth, both macroscopically as well as histologically. We hypothesize that the observed growth reduction with tannins could be the result of a changed energy and nutrient partitioning, i.e., more nutrients are directed to intestinal growth than for muscle growth., Competing Interests: Authors LG and NN were employed by Sanluc International NV.

- Abstract
Background: FDG-PET/CT has a high negative predictive value to detect residual nodal disease in patients with locally advanced squamous cell head and neck cancer after completing concurrent chemoradiotherapy (CCRT). However, the positive predictive value remains suboptimal due to inflammation after radiotherapy, generating unnecessary further investigations and possibly even surgery. We report the results of a preplanned secondary end point of the ECLYPS study regarding the potential advantages of dual time point FDG-PET/CT imaging (DTPI) in this setting. Standardized dedicated head and neck FDG-PET/CT images were obtained 12 weeks after CCRT at 60 and 120 min after tracer administration. We performed a semiquantitative assessment of lymph nodes, and the retention index (RI) was explored to optimize diagnostic performance. The reference standard was histology, negative FDG-PET/CT at 1 year, or > 2 years of clinical follow-up. The time-dependent area under the receiver operator characteristics (AUROC) curves was calculated., Results: In total, 102 subjects were eligible for analysis. SUV values increased in malignant nodes (median SUV
1 = 2.6 vs. SUV2 = 2.7; P = 0.04) but not in benign nodes (median SUV1 = 1.8 vs. SUV2 = 1.7; P = 0.28). In benign nodes, RI was negative although highly variable (median RI = - 2.6; IQR 21.2), while in malignant nodes RI was positive (median RI = 12.3; IQR 37.2) and significantly higher (P = 0.018) compared to benign nodes. A combined threshold (SUV1 ≥ 2.2 + RI ≥ 3%) significantly reduced the amount of false-positive cases by 53% (P = 0.02) resulting in an increased specificity (90.8% vs. 80.5%) and PPV (52.9% vs. 37.0%), while sensitivity (60.0% vs. 66.7%) and NPV remained comparably high (92.9% vs. 93.3%). However, AUROC, as overall measure of benefit in diagnostic accuracy, did not significantly improve (P = 0.62). In HPV-related disease (n = 32), there was no significant difference between SUV1 , SUV2 , and RI in malignant and benign nodes, yet this subgroup was small., Conclusions: DTPI did not improve the overall diagnostic accuracy of FDG-PET/CT to detect residual disease 12 weeks after chemoradiation. Due to differences in tracer kinetics between malignant and benign nodes, DTPI improved the specificity, but at the expense of a loss in sensitivity, albeit minimal. Since false negatives at the 12 weeks PET/CT are mainly due to minimal residual disease, DTPI is not able to significantly improve sensitivity, but repeat scanning at a later time (e.g. after 12 months) could possibly solve this problem. Further study is required in HPV-associated disease., (© 2022. The Author(s).)- Published

- Abstract
In 2 broiler trials, the effects of chestnut tannins on performance and meat quality (trial 1), and digestion (trial 2) were evaluated. In both trials, Ross 308 broilers received one of 2 basal diets: one basal diet contained corn and soy as main feed ingredients, while the challenge basal diet contained wheat, palm oil, and rapeseed meal. The composition of the basal diets was chosen to assess the interaction between chestnut tannins and diet composition. To both basal diets, chestnut tannins were added at 3 doses: 0 mg/kg (T-), 500 mg/kg (T+), or 2,000 mg/kg (T++), resulting in a total of 6 treatments. In trial 1, both basal diets containing 2,000 mg/kg chestnut tannins lowered broiler performance in grower and finisher phases. A tannin dose of 500 mg/kg had no effect on performance in either basal diet. Corn-based diets resulted in lower meat pH compared to wheat diets. Further, addition of chestnut tannins resulted in increased meat pH, and caused proportionally a lower meat drip loss and shear force for both basal diets. During the digestibility study (trial 2), blood was also collected. None of the treatments affected digestibility or blood parameters (glucose, non-esterified fatty acids, and triacylglycerols). Malondialdehyde (MDA) was measured in plasma to assess antioxidative properties of chestnut tannins. In wheat diets, chestnut tannins significantly lowered plasma MDA demonstrating its antioxidative nature. Regarding gut health, crypt depth decreased proportionally with the dosage of chestnut tannins in both basal diets with significantly shallower crypts for the wheat diets compared to the corn diets. Relative intestinal growth was stimulated in the wheat diets proportionally to the tannin dose based on the larger relative gut length. In conclusion, chestnut tannins did not influence digestive metabolism, yet they lowered performance at higher doses regardless of feed ingredients used in the diet. Tannins positively affected meat quality and when added to wheat diets, intestinal growth was stimulated and the antioxidative status of the broilers improved., (Copyright © 2021 The Authors.

- Abstract
Background: Falls affects one of three people after 65 years old, and it can lead to serious consequences. Scientific evidence point out that physical exercise is the most efficient way to prevent falls among older adults. Objective: The main objective of this study is to determine if a social marketing program can increase the attendance rate of people aged 60 and over at group balance workshops. Methods: This quasi-experimental multicenter study is being conducted in three French Regions (Loire, Haute-Loire and Rhône) over a period of 18 months. The Social Marketing Campaign will be done in three ways. Firstly, a Communication Campaign will take place in the two Test Areas but not in the Control Area. Secondly, flyers have been designed to be distributed by local partners. Finally, conferences for older people will be organized in the areas of intervention in order to reach the target audience for the program. The study will include people aged 60 and older who want to participate in the Balance Program. Results: The Crédit Agricole Loire/Haute-Loire Foundation funded the study and the Jean Monnet University of Saint-Etienne reviewed it. The Ethics Committee of the University Teaching Hospital of Saint-Etienne approved and peer-reviewed it on September 6, 2019, under Reference Number IRBN622019/CHUSTE. Conclusion: The results of this first study will demonstrate whether or not social marketing for promoting group balance workshops in the elderly will increase their attendanceship in adapted physical activity sessions, especially those that prevent falls.

- Abstract
Faced with an aging French population, the demand for unscheduled care is growing. In order to avoid referring elderly patients to emergency departments, which are unsuitable for them, the Regional Health Agencies have created telephone hot lines dedicated to geriatrics. They are exclusively accessible to general practitioners in order to obtain advice or a place in a geriatric hospital. General practitioners are rarely asked about the value of this tool in their practice., (Copyright © 2021 Elsevier Masson SAS. All rights reserved.)

- Abstract
In February 2021, France had more than 76,000 deaths due to COVID-19 and older adults were heavily affected. Most measures taken to reduce the impact of COVID-19 (quarantine, visit ban in nursing home, etc.) significantly influenced the lives of older adults. Yet they were rarely consulted about their implementation. Exclusion of and discrimination against older adults has been accentuated during the COVID-19 pandemic. While many articles discussing COVID-19 also mention ageism, few actually incorporate the perspectives and opinions of older adults. Our research aims to assess the ageism experienced by older adults during the COVID-19 pandemic. We conducted interviews with older adults (63-92 years, mean age = 76 years) in an urban area of France. Participants reported experiencing more ageism during the COVID-19 pandemic, including hostile and benevolent ageism from older adults' families. Despite reports of experiencing ageist attitudes and behaviors from others, however, older adults also identified positive signs of intergenerational solidarity during this COVID-19 crisis., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Barth, Guyot, Fraser, Lagacé, Adam, Gouttefarde, Goethals, Bechard, Bongue, Fundenberger and Célarier.)

- Abstract
Objective: Our aim was to give an overview of the effectiveness of adjunctive analgesics in head and neck cancer (HNC) patients receiving (chemo-) radiotherapy., Design: Systematic review., Interventions: This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Embase, Web of Science, the Cochrane Library, and ClinicalTrials.gov were searched for studies concerning "head neck cancer," "adjunctive analgesics," "pain," and "radiotherapy.", Outcome Measures: Pain outcome, adverse events, and toxicity and other reported outcomes, for example, mucositis, quality of life, depression, etc., Results: Nine studies were included in our synthesis. Most studies were of low quality and had a high risk of bias on several domains of the Cochrane Collaboration tool. Only two studies comprised high-quality randomized controlled trials in which pregabalin and a doxepin rinse showed their effectiveness for the treatment of neuropathic pain and pain from oral mucositis, respectively, in HNC patients receiving (chemo-) radiotherapy., Conclusions: More high-quality trials are necessary to provide clear evidence on the effectiveness of adjunctive analgesics in the treatment of HNC (chemo-) radiation-induced pain., (© The Author(s) 2020.

- Abstract
Background: Previous cohorts studied the association of various types of physical activities with the incidence of cognitive disorders. The objective of this work was to analyze the association of leisure, domestic and professional physical activities with mild and moderate cognitive disorders in older people living in the community. Methods: We used retrospective data from the "FRéLE" (FRagilité: étude Longitudinale de ses Expressions) a longitudinal and observational study. Data collected included socio-demographic variables, lifestyle and health status. Cognitive disorders were assessed using the Montreal Cognitive Assessment (MoCA). Two cut-offs of MoCA were used to analyze mild and moderate cognitive disorders. Physical activity was assessed by the Physical Activity Scale for the Elderly (PASE) structured in three sections: leisure, household, and professional activities. Spline and logistic regression models were used to estimate the risk of cognitive disorders. Results: At baseline, 428 participants (for study of mild disorders) and 1,271 participants (for study of moderate disorders) without cognitive disorders were included in the analysis. The mean ages were 74 and 78 years, respectively. After a 2-year follow-up, we found mild cognitive disorders in 154 participants (36%) and 71 cases of moderate cognitive disorders (5.6%). In multi-adjusted logistic models, domestic activities were associated with cognitive disorders, but not leisure and professional activities. Conclusion: We found an inverse relation between domestic sub-score and cognitive disorders defined by MoCA < 18. With a specific questionnaire and quantitative information on the type of activities, this study contributed to the debate on the beneficial effects of physical activity on cognition., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2020 Dupré, Hupin, Goethals, Béland, Roche, Célarier, Carrière, Barth and Bongue.)

- Abstract
Background: Noncommunicable diseases (NCDs) are the leading causes of death worldwide. They were responsible for 40 million of the 57 million deaths recorded worldwide in 2016. In Cameroon, epidemiological studies have been devoted to NCDs and their risk factors. However, none provides specific information on their extent or the distribution of their risk factors within the Cameroonian defense forces., Objective: The objective of our study was to assess the cardiovascular risk of a Cameroonian military population compared with that of its neighboring civilian population., Methods: We conducted a cross-sectional study that involved subjects aged 18 to 58 years, recruited from October 2017 to November 2018 at the Fifth Military Sector Health Center in Ngaoundéré, Cameroon. Data collection and assessment were done according to the World Health Organization (WHO)'s STEPS manual for surveillance of risk factors for chronic NCDs and the Alcohol Use Disorders Identification Test. Five cardiovascular risk factors were assessed: smoking, harmful alcohol consumption, obesity/overweight, hypertension, and diabetes. The risk was considered high in subjects with 3 or more of the factors. Univariate analysis and multivariate logistic regression were carried out according to their indications., Results: Our study sample of 566 participants included 295 soldiers and 271 civilians of the same age group (median age 32 years versus 33 years, respectively; P=.57). The military sample consisted of 31 officers and 264 noncommissioned officers (NCOs). Soldiers were more exposed to behavioral risk factors than civilians, with a prevalence of smoking of 13.9% versus 4.4% (P<.001) and excessive alcohol consumption of 61.7% versus 14.8% (P<.001). They also presented with a higher cardiovascular risk than civilians (odds ratio 2.7, 95% CI 1.50-4.81; P<.001), and among the military participants, the cardiovascular risk was higher for officers than for NCOs (51.6% versus 14.0%, respectively; P<.001)., Conclusions: Cameroonian soldiers are particularly exposed to cardiovascular behavioral risk factors and consequently are at higher risk of NCDs., Trial Registration: ClinicalTrials.gov NCT04315441; https://clinicaltrials.gov/ct2/show/NCT04315441., (©Williams Bell Ngan, Lawrence Essama Eno Belinga, Alain Serges Patrick Essam Nlo'o, Frederic Roche, Luc Goethals, Samuel Honoré Mandengue, Bienvenu Bongue.

Background: COVID-19 has infected millions of people worldwide, particularly in older adults. The first cases of possible reinfection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were reported in April 2020 among older adults., Design/setting: In this brief report, we present three geriatric cases with two episodes of SARS-CoV-2 infection separated by a symptom-free interval., Participants: The participants of this brief report are three cases of hospitalized geriatric women., Measurements/results: We note clinical and biological worsening during the second episode of COVID-19 for all three patients. Also, there is a radiological aggravation. The second episode of COVID-19 was fatal in all three cases., Conclusion: This series of three geriatric cases with COVID-19 diagnosed two times apart for several weeks questions the possibility of reinfection with SARS-CoV-2. It raises questions in clinical practice about the value of testing for SARS-CoV-2 infection again in the event of symptomatic reoccurrence.

- Abstract
Background: Falls are a significant source of morbidity in people aged 65 and over, affecting one in three people in this age group. The scientific evidence indicates that physical activity is the most effective method for preventing falls among seniors. Although public health professionals often use social marketing to design and plan successful interventions, its use to promote physical activity and prevent falls among older people remains low. This article aims to provide a new systematic literature review of social marketing interventions promoting physical activity and targeting people aged 60 and over., Methods: Following CRD's guidance and PRISMA guidelines, we searched between January 2008 and July 2019 for relevant articles in five primary databases using predefined search and inclusion criteria. Two independent reviewers analysed the selected articles to identify evidence of the seven social marketing benchmark criteria, defined by experts in the field as the common elements that contribute to social marketing success., Results: The final review included nine studies. Of the studies selected, three specifically targeted over 60-year-olds, whereas the others segmented the population into several age-based subcategories, including over 60-year-olds. Eight studies highlighted positive results for the participants with an increase in participation or an increase in physical activity level. None of the nine studies selected for this systematic review implemented the entire social marketing approach., Conclusion: Few published interventions use the seven social marketing criteria. Further research is required to encourage uptake and inclusion in successful social marketing interventions to increase program effectiveness in this target population.

- Abstract
Background: Older adults and those with pre-existing medical conditions are at risk of death from severe acute respiratory syndrome coronavirus 2 (SARS CoV-2). In this period of quarantine, one of the reasons for going out is physical activity. This issue is important, as the impact of a sedentary lifestyle might be lower for children and young adults, but is far more severe for older adults. Although older adults need to stay at home because they have a higher risk of coronavirus disease (COVID-19), they need to avoid a sedentary lifestyle. Physical activity is important for older adults, especially to maintain their level of independence, mental health, and well-being. Maintaining mobility in old age is necessary, as it may predict loss of independence in older adults., Objective: Our first objective was to evaluate the impact of this quarantine period on physical activity programs and on the physical and mental health of older adults. Our second objective was to discuss alternatives to physical activity programs that could be suggested for this population to avoid a sedentary lifestyle., Methods: We conducted a qualitative survey using semistructured interviews with professionals (managers in charge of physical activity programs for older adults and sports trainers who run these physical activity programs) from the French Federation of Physical Education and Voluntary Gymnastics (FFPEVG) and older adults participating in a physical activity program of the FFPEVG. We followed a common interview guide. For analysis, we carried out a thematic analysis of the interviews., Results: This study suggests that the COVID-19 epidemic has affected, before quarantine measures, the number of seniors attending group physical activity programs in the two study territories. In addition, despite the decline in their participation in group physical activities before the quarantine, older adults expressed the need to perform physical activity at home. There is a need to help older adults integrate simple and safe ways to stay physically active in a limited space. A national policy to support older adults for physical activity at home appears essential in this context., Conclusions: Given the results of our study, it seems necessary to globally communicate how important it is for older adults to maintain physical activity at home. We are concerned about the level of independence and mental health state of older adults after the end of quarantine if there is no appropriate campaign to promote physical activity among them at home., (©Luc Goethals, Nathalie Barth, Jessica Guyot, David Hupin, Thomas Celarier, Bienvenu Bongue.

- Abstract
Background: The Hopkins criteria were introduced for nodal response evaluation after therapy in head and neck cancer, but its superiority over quantification is not yet confirmed., Methods: SUV
body weight thresholds and lesion-to-background ratios were explored in a prospective multicenter study of standardized FDG-PET/CT 12 weeks after CRT in newly diagnosed locally advanced head and neck squamous cell carcinoma (LAHNSCC) patients (ECLYPS). Reference standard was histology, negative FDG-PET/CT at 12 months after treatment or ≥ 2 years of negative follow-up. Area under the receiver operator characteristics curves (AUROC) were estimated and obtained thresholds were validated in an independent cohort of HNSCC patients (n = 127)., Results: In ECLYPS, 124 patients were available for quantification. With a median follow-up of 20.4 months, 23 (18.5%) nodal neck recurrences were observed. A SUV70 threshold of 2.2 (AUROC = 0.89; sensitivity = 79.7%; specificity = 80.8%) was identified as optimal metric to identify nodal recurrence within 1 year after therapy. For lesion-to-background ratios, an SUV50 /SUVliver threshold of 0.96 (AUROC = 0.89; sensitivity = 79.7%; specificity = 82.8%) had the best performance. Compared with Hopkins criteria (AUROC = 0.81), SUV70 and SUV50 /SUVliver provided a borderline significant (p = 0.040 and p = 0.094, respectively) improvement. Validation of thresholds yielded similar AUROC values (SUV70 = 0.93, SUV50 /SUVliver = 0.95), and were comparable to the Hopkins score (AUROC = 0.91; not statistically significant)., Conclusion: FDG quantification detects nodal relapse in LAHNSCC patients. When using EARL standardized PET acquisitions and reconstruction, absolute SUV metrics (SUV70 threshold 2.2) prove robust, yet ratios (SUV50 /SUVliver , threshold 0.96) may be more useful in routine clinical care. In this setting, the diagnostic value of quantification is comparable to the Hopkins criteria., Trial Registration: US National Library for Medicine, NCT01179360.

- Abstract
Background: In France, emergency departments (EDs) are the fastest and most common means for general practitioners (GPs) to cope with the complex issues presented by elderly patients with multiple conditions. EDs are overburdened, and studies show that being treated in EDs can have a damaging effect on the health of elderly patients. Outpatient care or planned hospitalizations are possible solutions if appropriate geriatric medical advice is provided. In 2013, France's regional health authorities proposed creating direct telephone helplines, "geriatric hotlines," staffed by geriatric specialists to encourage interactions between GP clinics and hospitals. These hotlines are designed to improve health care pathways and the health status of the elderly., Objective: This study aims to describe the health care pathways and health status of patients aged 75 years and older hospitalized in short-stay geriatric wards following referral from a geriatric hotline., Methods: The study will be conducted over 24 months in seven French university hospital centers. It will include all patients aged 75 and older, living in their own homes or nursing homes, who are admitted to short-stay geriatric wards following hotline consultation. Two questionnaires will be filled out by medical staff at specific time points: (1) after conducting the telephone consultation and (2) on admitting the patient to a short-stay geriatric medical care. The primary endpoint will be mean hospitalization duration. The secondary endpoints will be intrahospital mortality rate, the characteristics of patients admitted via the hotline, and the types of questions asked and responses given via the hotline., Results: The study was funded by the National School for Social Security Loire department (École Nationale Supérieure de Sécurité Sociale) and the Conference for funders of prevention of autonomy loss for the elderly of the Loire department in November 2017. Institutional review board approval was obtained in April 2018. Data collection started in May 2018; the planned end date for data collection is May 2020. Data analysis will take place in the summer of 2020, and the first results are expected to be published in late 2020., Conclusions: The results will reveal whether geriatric hotlines provide the most effective management of elderly patients, as indicated by shorter mean hospitalization durations. Shorter hospital durations could lead to a reduced risk of complications-geriatric syndromes-and the domino chain of geriatric conditions that follow. We will also describe different geriatric hotlines from different cities and compare how they function to improve the health care of the elderly and pave the way toward new advances, especially in the organization of the care path., Trial Registration: ClinicalTrials.gov NCT03959475; https://clinicaltrials.gov/ct2/show/NCT03959475., International Registered Report Identifier (irrid): DERR1-10.2196/15423., (©Laure Martinez, Noémie Lacour, Régis Gonthier, Marc Bonnefoy, Luc Goethals, Cedric Annweiler, Nathalie Salles, Nathalie Jomard, Jérôme Bohatier, Magali Tardy, Etienne Ojardias, Romain Jugand, Bienvenu Bongué, Thomas Celarier.

- Abstract
Intra-abdominal fat is abundantly present in both the peritoneum and retroperitoneum. Fat necrosis or inflammation are common findings in abdominal imaging. The most common pathologies that we encounter are epiploic appendagitis, omental infarction, mesenteric panniculitis, and encapsulated fat necrosis. Less common entities that can occur are pancreatic saponification, heterotopic mesenteric ossification, and pseudolipoma of the capsule of Glisson. These entities can mimic more urgent pathologies such as appendicitis, diverticulitis, or malignancies., Competing Interests: The authors report no conflict of interest., (Copyright © Polish Medical Society of Radiology 2020.)

- Abstract
Objectives: Research has indicated that cancer-related cognitive impairments (CRCI) may be influenced by psychosocial factors such as distress, worry and fatigue. Therefore, we aimed to validate the distress thermometer (DT) as a screening tool to detect CRCI six months post-treatment-initiation in a group of general cancer patients., Methods: Patients (≥18 years, n = 125) with a histologically confirmed diagnosis of a solid cancer or hematological malignancy, scheduled for a curative treatment, were evaluated at baseline (T0) and six months post-treatment-initiation (T1) for CRCI by a neuropsychological assessment, including patient-reported outcome measures (PROMs). Assessed cognitive domains included premorbid intelligence, attention, processing speed, flexibility, verbal and visual episodic memory and verbal fluency. PROMs entailed distress (DT, cut-off ≥4, range 0-10), anxiety and depression, fatigue (FACIT-fatigue scale) and subjective cognitive complaints., Results: At T0, 60.4% of patients showed a DT score of ≥4, whereas 50% met this criterion at T1. According to the definition of the International Cognition and Cancer Task Force, 25.5% and 28.3% of patients presented with a CRCI at T0 and T1, respectively. When evaluating the DT as a screening tool for CRCI at T1, data showed an inverse relationship between the DT and CRCI. ROC-curve analysis revealed an AUC <0.5. ROC-curve analyses evaluating the DT and FACIT-fatigue scale as screening tools for subjective cognitive complaints showed an AUC ± SE of, respectively, 0.642 ± 0.067 and 0.794 ± 0.057., Conclusions: The DT at T0 cannot be used to screen for objective CRCI at T1, but both the DT and FACIT-fatigue scale at T0 showed potential as screening tools for subjective cognitive complaints at T1.

- Abstract
Introduction: Recent research in the field of cancer-related cognitive impairments (CRCI) has shown CRCI presentation prior to treatment initiation. Some have attributed these problems to worry and fatigue, whereas others have suggested an influence of age, IQ, and other psychosocial and medical factors., Methods: Patients (≥18 years) with a histologically confirmed diagnosis of a solid cancer or hematological malignancy, scheduled for a curative treatment, were evaluated with a baseline neuropsychological assessment including Patient-Reported Outcome Measures (PROMs). PROMs entailed distress, anxiety and depression, fatigue, and cognitive complaints. The neuropsychological assessment comprised several cognitive domains such as premorbid IQ, attention, processing speed, flexibility, verbal and visual episodic memory, and verbal fluency., Results: Cross-sectional data of 125 patients were collected. Patients had a mean age of 60.9 years (range: 30.0-85.0) and comprised primarily females (65.6%). Patients presented with cancer of following sites: breast (44.0%), digestive (28.8%), urological (11.2%), gynecologic (8.0%), hematologic malignancy (4.8%), and lung (3.2%). Patients presented with a premorbid IQ of 105.3 (range: 79.0-124.0). In 29.6% of patients, a CRCI was detected. Binary logistic regression analyses showed that a lower premorbid IQ (β = -.084, P < .01) and a higher level of fatigue (β = -.054, P < .05) predicted baseline CRCI. Premorbid IQ also predicted performance on individual cognitive domains. Some domains were also influenced by age, gender, having a breast cancer diagnosis, and an active treatment for hypertension., Conclusion: Premorbid IQ and fatigue are important predictors of baseline CRCI. Therefore, we advise researchers to implement a short IQ test when conducting clinical trials on CRCI., (Copyright © 2016 John Wiley & Sons, Ltd.)

- Abstract
Prostate-specific membrane antigen (PSMA) is a cell surface glycoprotein which is frequently overexpressed on prostate cancer cells. Ga-PSMA PET/CT plays an increasing role in prostate cancer management. However, growing evidence suggests increased PSMA uptake in a variety of other malignant tumor entities and in some benign lesions. This report describes PSMA uptake in numerous thoracic lymph nodes in a patient with known mediastinal sarcoidosis. Knowledge and recognition of these possibilities are important to avoid scan misinterpretation.

- Abstract
Ga-PSMA plays an increasing role in prostate cancer management, but several instances of false positivity have now been recognized. We present a patient with metastatic prostatic carcinoma who also showed overexpression of PSMA in Paget disease of the humerus on Ga-PSMA PET. This probably relates to bone remodeling and increased vascularity. It is important to be aware of this aspecific uptake because its recognition may avoid overstaging and may alter the therapeutic choice.

- Abstract
Prostate-specific membrane antigen (PSMA) is a cell surface glycoprotein, which is frequently overexpressed on prostate cancer cells. A Ga-PSMA PET/CT can be used for early detection of lymph node or bone metastases after radical prostatectomy when there is biochemical recurrence. This report describes PSMA uptake in a healing fracture masquerading as metastatic bone disease in a patient with a history of prostate adenocarcinoma. Clinicians reporting Ga-PSMA PET/CT should be aware of this potential important pitfall.

- Abstract
Modulating the activity of tumor-infiltrating dendritic cells (TiDC) provides opportunities for novel cancer interventions. In this article, we report on our study of the uptake of mRNA by CD8α(+) cross-presenting TiDCs upon its intratumoral (i.t.) delivery. We exploited this property to deliver mRNA encoding the costimulatory molecule CD70, the activation stimuli CD40 ligand, and constitutively active Toll-like receptor 4, referred to as TriMix mRNA. We show that TiDCs are reprogrammed to mature antigen-presenting cells that migrate to tumor-draining lymph nodes (TDLN). TriMix stimulated antitumor T-cell responses to spontaneously engulfed cancer antigens, including a neoepitope. We show in various mouse cancer models that i.t. delivery of TriMix mRNA results in systemic therapeutic antitumor immunity. Finally, we show that the induction of antitumor responses critically depends on TiDCs, whereas it only partially depends on TDLNs. As such, we provide a platform and a mechanistic rationale for the clinical testing of i.t. administration of TriMix mRNA., (©2015 American Association for Cancer Research.)

- Abstract
Background: Evidence-based guidelines concerning the older head and neck cancer (HNCA) patient are lacking. Accurate patient selection for optimal care management is therefore challenging. We examined if geriatric assessment is indicative of long-term health-related quality of life (HRQOL) and overall survival in this unique population., Methods: All HNCA patients, aged ≥65 years, eligible for curative radio(chemo)therapy were evaluated with the Geriatric-8 (G-8) questionnaire and a comprehensive geriatric assessment (CGA). Euroqol-5 dimensions (EQ-5D) and survival were collected until 36 months post treatment start. Repeated measures ANOVA was applied to analyse HRQOL evolution in 'fit' and 'vulnerable' patients, defined by G-8. Kaplan-Meier curves and cox proportional hazard analysis were established for determination of the prognostic value of geriatric assessments. Quality-adjusted survival was calculated in both patient subgroups., Results: One hundred patients were recruited. Seventy-two percent of patients were considered vulnerable according to CGA (≥2 abnormal tests). Fit patients maintained a relatively acceptable long-term HRQOL, whilst vulnerable patients showed significantly lower median health states. The difference remained apparent at 36 months. Vulnerability, as classified by G-8 or CGA, came forward as independent predictor for lower EQ-5D index scores. After consideration of confounders, a significantly lower survival was observed in patients defined vulnerable according to G-8, compared to fit patients. A similar trend was seen based on CGA. Calculation of quality-adjusted survival showed significantly less remaining life months in perfect health in vulnerable patients, compared to fit ones., Conclusions: G-8 is indicative of quality-adjusted survival, and should be considered at time of treatment decisions for the older HNCA patient.

- Abstract
Unlabelled: Schnitzler's syndrome is a rare disease characterized by a monoclonal IgM (or IgG) paraprotein, a nonpruritic urticarial skin rash, and 2 (or 3) of the following: recurrent fever, objective signs of abnormal bone remodeling, elevated CRP level or leukocytosis, and a neutrophilic infiltrate on skin biopsy. It responds well to treatment with the interleukine-1-inhibitor anakinra. We report the bone scintigraphy and MRI findings in a 45 years old man with this syndrome and compare them with data from the literature., Conclusion: None of the imaging findings are specific, but they lead to a differential diagnosis including infiltrative diseases (e.g. systemic mastocytosis or Erdheim-Chester disease) and dysplastic diseases (e.g. melorheostosis, Camurati-Engelmann disease or van Buchem disease). The bone scintigraphy pattern may be very suggestive of the correct diagnosis and of bone involvement in this syndrome.

- Abstract
Background: Therapy-induced mucositis and dysphagia puts head and neck (H&N) cancer patients at increased risk for developing cachexia. Omega-3 fatty acids (n-3 FA) have been suggested to protect against cachexia. We aimed to examine if echium oil, a plant source of n-3 FA, could reduce weight loss in H&N cancer patients undergoing radio(chemo)therapy with curative intent., Methods: In a double-blind trial, patients were randomly assigned to echium oil (intervention (I) group; 7.5 ml bis in die (b.i.d.), 235 mg/ml α-linolenic acid (ALA) + 95 mg/ml stearidonic acid (SDA) + 79 mg/ml γ-linolenic acid (GLA)) or n-3 FA deficient sunflower oil high oleic (control (C) group; 7.5 ml b.i.d.) additional to standard nutritional support during treatment. Differences in percentage weight loss between both groups were analysed according to the intention-to-treat principle. Erythrocyte FA profile, body composition, nutritional status and quality of life were collected., Results: Ninety-one eligible patients were randomised, of whom 83 were evaluable. Dietary supplement adherence was comparable in both groups (median, I: 87%, C: 81%). At week 4, the I group showed significantly increased values of erythrocyte n-3 eicosapentanoic acid (EPA, 14% vs -5%) and n-6 GLA (42% vs -20%) compared to the C group, without a significant change in n-6 arachidonic acid (AA, 2% vs -1%). Intention-to-treat analysis could not reveal a significant reduction in weight loss related to echium oil consumption (median weight loss, I: 8.9%, C: 7.6%). Also, no significant improvement was observed in the other evaluated anthropometric parameters., Conclusions: Echium oil effectively increased erythrocyte EPA and GLA FAs in H&N cancer patients. It failed however to protect against weight loss, or improve nutritional parameters., Trial Registration: ClinicalTrials.gov Identifier NCT01596933.

- Abstract
Objective: We aimed to validate the Freund Clock Drawing Test (CDT), with its predefined cutoff score of ≤4, as a screening tool to detect elderly cancer patients in need of a more in-depth cognitive evaluation within a comprehensive geriatric assessment (CGA)., Methods: Patients aged 70 years or older with a histologically confirmed diagnosis of cancer were evaluated with a full CGA, including CDT and Folstein Mini Mental State Examination (MMSE) as gold standard. Validation of the Freund CDT was defined in terms of diagnostic accuracy of the test through receiver operating characteristics (ROC)-analysis. To accept the Freund CDT as a screening tool, we estimated that the area under the ROC curve (AUC) had to differ significantly from 0.70 with an AUC of at least 0.85., Results: Two hundred elderly cancer patients with a mean age of 79.0 years were included. Four patients were excluded from the analyses because of invalid results. Potential cognitive impairment (MMSE ≤23) was observed in 27.0% of patients. Based on of the AUC ± SE, the Freund CDT showed excellent diagnostic performance (0.95 ± 0.17). Furthermore, it provided excellent sensitivity (94.3%) and high specificity (87.4%)., Conclusions: Our results indicate that the Freund CDT can be used as an initial screening tool to detect elderly cancer patients in need of a more in-depth cognitive assessment within CGA, instead of the MMSE., (Copyright © 2014 John Wiley & Sons, Ltd.)

- Abstract
Background: The radiation recall reaction (RRR) is an inflammatory reaction that occurs in previously irradiated areas. The phenomenon is probably due to an idiosyncratic hypersensitivity reaction, in which a second agent can recall the inflammatory reaction., Case Report: This case report documents a cold-weather-induced radiation recall dermatitis (RRD). We observed a severe RRD in a patient after chemoradiotherapy treatment with cisplatin for a nasopharyngeal carcinoma, precipitated by cold temperatures, which developed 9 days after completion of therapy. In the medical literature, RRD following extreme cold temperatures seems to be a peculiar event., Conclusion: Until further information on the interaction is available, future studies on combined chemotherapy with cisplatin should be carefully monitored and any side effects clearly documented. This case suggests that environmental conditions may play a contributing role in the development of RRD. This case also implies that neither fraction size nor total radiation dose is a determining factor in the development of the dermatologic reaction.

- Abstract
Head and neck (H&N) cancer is mainly a cancer of the elderly; however, the implementation of comprehensive geriatric assessment (CGA) to quantify functional age in these patients has not yet been studied. We evaluated the diagnostic performance of screening tools [Vulnerable Elders Survey-13 (VES-13), G8 and the Combined Screening Tool 'VES-13 + (17-G8)' or CST], the feasibility of serial CGA, and correlations with health-related quality of life evolution [HRQOL; European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires (EORTC QLQ)-C30 and -HN35] during therapy in hundred patients, aged ≥65 years, with primary H&N cancer undergoing curative radio(chemo)therapy. Respectively 36.8%, 69.0%, 62.1% and 71.3% were defined vulnerable according to VES-13, G8, CST and CGA at week 0, mostly due to presence of severe grade co-morbidities, difficulties in community functioning and nutritional problems. At week 4, significantly more patients were identified vulnerable due to nutritional, functional and emotional deterioration. The CST did not achieve the predefined proportion necessary for validation. Vulnerable patients reported lower function and higher symptom HRQOL scores as compared with fit patients. A comparable deterioration in HRQOL was observed in both groups through therapy. In conclusion, G8 remains the screening tool of choice. Serial CGA identifies the evolution of multidimensional health problems and HRQOL conditions during therapy with potential to guide individualised supportive care., (© 2014 John Wiley & Sons Ltd.)

- Abstract
Objective: To translate spermatogonial stem cell (SSC) transplantation towards a clinical application., Design: Mouse green fluorescent protein (GFP)-positive testicular cells were labeled with (99m)technetium and microbubbles. These labeled cells were injected into the rete testis of isolated human testes under ultrasound guidance. Three different conditions were tested: 1) 800 μL of a 20 million cells/mL suspension; 2) 800 μL of a 10 million cells/mL suspension; and 3) 1,400 μL of a 10 million cells/mL suspension. After injection, the human cadaver testes were analyzed with the use of single-photon-emission computerized tomography (SPECT) imaging and histology., Setting: Laboratory research environment., Patient(s): Cadaver testes, obtained from autopsies at the pathology department., Intervention(s): Ultrasound-guided injection of mouse GFP-positive testicular cells., Main Outcome Measure(s): Presence of radioactive-labeled cells in the human cadaver testes and GFP-positive cells in the seminiferous tubules., Result(s): In all of the experimental groups, GFP-positive cells were observed in the seminiferous tubules, near and far from the rete testis, but also in the interstitium. On SPECT, significant difference was seen between the group injected with 800 μL of a 20 million cells/mL suspension (1,654.6 ± 907.6 mm³) and the group injected with 1,400 μL of a 10 million cells/mL suspension (3,614.9 ± 723.1 mm³). No significant difference was reached in the group injected with 800 μL of a 10 million cells/mL suspension., Conclusion(s): Injecting cells in the human cadaver testis is feasible, but further optimization is required., (Copyright © 2013 American Society for Reproductive Medicine.
