Abstract
Surgical resection remains the gold standard for liver tumor treatment, yet the emergence of post-operative liver failure, known as the small for size syndrome (SFSS), poses a significant challenge. The activation of hypoxia sensors in a SFSS liver remnant initiated early angiogenesis, improving vascular architecture, safeguarding against liver failure and reducing mortality. The study aimed to elucidate vascular remodeling mechanisms in SFSS, its impact on hepatocyte function and subsequent liver failure. Mice underwent extended partial hepatectomy to induce SFSS, with a subset exposed to hypoxia immediately after surgery. Hypoxia bolstered post-hepatectomy survival rates. Early proliferation of liver sinusoidal cells, coupled with recruitment of putative endothelial progenitor cells (EPC), increased vascular density, improved lobular perfusion, and limited hemorrhagic events in the regenerating liver under hypoxia. Administration of granulocyte colony stimulating factor (G-CSF) in hepatectomized mice mimicked the effects of hypoxia on vascular remodeling and EPC recruitment, but failed to rescue survival. Compared to normoxia, hypoxia favored hepatocyte function over proliferation, promoting functional preservation in the regenerating remnant. Injection of AAV8-TBG-HNF4α virus for hepatocyte-specific overexpression of HNF4α, the master regulator of hepatocyte function, enforced functionality in proliferating hepatocytes but did not rescue survival. The combination of HNF4α overexpression and G-CSF treatment rescued survival after SFSS-setting hepatectomy. In summary, SFSS arises from an imbalance and desynchronized interplay between functional regeneration and vascular restructuring. To improve survival following SFSS-hepatectomy, it is essential to adopt a two-pronged strategy aimed at preserving the function of proliferating parenchymal cells and simultaneously attenuating vascular damage.

Abstract
For the past decade, three-dimensional (3D) culture models have been emerging as powerful tools in translational research to overcome the limitations of two-dimensional cell culture models. Thanks to their ability to recapitulate the phenotypic and molecular heterogeneity found in numerous organs, organoids have been used to model a broad range of tumors, such as colorectal cancer. Several approaches to generate organoids exist, with protocols using either pluripotent stem cells, embryonic stem cells, or organ-restricted adult stem cells found in primary tissues, such as surgical resections as starting material. The latter, so-called patient-derived organoids (PDOs), have shown their robustness in predicting patient drug responses compared to other models. Because of their origin, PDOs are natural offspring of the patient tumor or healthy surrounding tissue, and therefore, have been increasingly used to develop targeted drugs and personalized therapies. Here, we present a new protocol to generate patient-derived colon organoids (PDCOs) from tumor and healthy tissue biopsies. We emphasize budget-friendly and reproducible techniques, which are often limiting factors in this line of research that restrict the development of this 3D-culture model to a small number of laboratories worldwide. Accordingly, we describe efficient and cost-effective techniques to achieve immunoblot and high-resolution microscopy on PDCOs. Finally, a novel strategy of lentiviral transduction of PDCOs, which could be applied to all organoid models, is detailed in this article. © 2023 The Authors.

Abstract
BACKGROUND Adrenocortical carcinoma is a rare and aggressive tumour. The only curative treatment is surgery with negative margins. In most series, the average lesion size ranges from 5.5 to 15 cm. METHODS We report the case of a 27-year-old female with hyperandrogenism and Cushing syndrome due to a right adrenocortical carcinoma of 19.7 cm. RESULTS The tumour abutting on liver and vena cava and the presence two nodules in liver required extensive surgery including a right posterior sectionectomy and an en bloc resection of the adrenal mass together with the right kidney and the gallbladder. The vena cava was also resected with a reconstruction using a pericardial patch since it was invaded on its border. Pathological examination confirmed an adrenocortical carcinoma, with tumour invasion of vessels, tumour capsule, vena cava and two metastases in the liver (pT4N0M1). All margins were negative. Three months after surgery, two lung nodules, cardio-phrenic and internal mammary adenomegalies were noticed on a PET/CT scan, justifying the initiation of chemotherapy, alongside with mitotane. After a 10-month follow-up, CT scan was stable excepted for a lung nodule growing from 4 to 7 mm. Targeted stereotaxic radiotherapy was then administered. Twenty-two months after surgery, the patient has improved considerably and all signs of hyperandrogenism and Cushing syndrome have resolved. CONCLUSION This case of adrenocortical carcinoma illustrates one of the largest tumours among those reported. It demonstrates the feasibility and effectiveness of a multimodal approach in its treatment even if it is giant and at high risk.

Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Abstract
Although Glyphosate-based herbicides are often marketed as environmentally friendly and easily biodegradable, its bioavailability and risks to wildlife raise significant concerns. Among non-target organisms, earthworms which live in close contact with the soil can be directly exposed to pesticides and harmed. We investigated soil contamination and the exposure of earthworms to glyphosate, its metabolite AMPA, and glufosinate in an arable landscape in France, both in treated (i.e. temporary grasslands and cereal fields under conventional farming), and nontreated habitats (i.e. hedgerows, permanent grasslands and cereal fields under organic farming) (n = 120 sampling sites in total). Glyphosate, AMPA and glufosinate were detected in 88%, 58% and 35% of the soil samples, and in 74%, 38% and 12% of the earthworm samples, respectively. For both glyphosate and AMPA, concentrations in soils were at least 10 times lower than predicted environmental concentrations. However, the maximum glyphosate soil concentration measured (i.e., 0.598 mg kg-1) was only 2 to 3 times lower than the concentrations revealed to affect earthworms (survival and avoidance) in the literature. These compounds were found both in conventional and organic farming fields, thus supporting a recent study, and for the first time they were detected in hedgerows and grasslands. However, glyphosate and AMPA were more frequently detected in soils from cereal fields and hedgerows than in grasslands, and median concentrations measured in soils from cereal fields were significantly higher than in the two other habitats. Bioaccumulation of glyphosate and AMPA in earthworms was higher than expected according to the properties of the molecules. Our findings raised issues about the high occurrence of glyphosate and AMPA in soils from cropped and more natural areas in arable landscapes. They also highlight the potential for transfer of these molecules in terrestrial food webs as earthworms are prey for numerous animals.

Abstract
BACKGROUND Graves' disease may be associated with thyroid cancer, particularly differentiated thyroid cancer. Medullary thyroid cancer (MTC) is less common. The occurrence of sporadic MTC in Graves' disease in the presence of a RET proto-oncogene has never been reported. CLINICAL PRESENTATION A 63-year-old woman was referred for Graves' disease. A thyroid ultrasound disclosed five nodules, one of which was classified as Eu-Tirads 5 with a size of 6.7 × 6.5× 11 mm. Fine needle aspiration was reported as Bethesda class IV follicular neoplasm of a Hürthle cell subtype. Calcitonin level was found to be elevated. A total thyroidectomy confirmed the diagnosis of MTC and a bilateral cervical lymphadenectomy was performed, with four lymph nodes being infiltrated by MTC. Genetic testing revealed a M918T mutation in the RET proto-oncogene. CONCLUSION MTC may occur in Graves' disease, especially if a nodule is present. In this case, genetic testing should always be performed even if MTC is sporadic. Increased incidence of thyroid cancer in autoimmune thyroid diseases, as well as the link existing between autoimmunity, inflammation and carcinogenesis, leads us to hypothesize that the association here reported is not coincidental.

Abstract
Surgery is the ideal treatment of insulinoma. However, systemic therapy may be required to prevent severe preoperative hypoglycaemia, when surgery is contraindicated, delayed or refused and in case of unresectable metastatic disease. Diazoxide is commonly used but is not always effective and can cause serious side effects. Somatostatin analogues (octreotide and lanreotide) may be an alternative option. We report the case of a 27-year-old patient with insulinoma in whom diazoxide was compared with lanreotide before operation. A diagnosis of insulinoma was made on the basis of a fasting test and a 2 cm tumour confirmed in the body of the pancreas, with a high uptake of 111-In-pentreotide. Diazoxide was initiated and increased to a maximal tolerated dose of 450 mg/day. Because of dyspnoea and persisting hypoglycaemia, diazoxide was shifted to lanreotide 120 mg. All symptoms resolved without hypoglycaemia. According to the EORTC quality score of life, the score without treatment, under diazoxide, under lanreotide and after surgery were respectively 84.7, 73.3, 90.9 and 99.1. Thus, providing a positive Octreoscan, somatostatin analogues may be a safe, effective and well-tolerated option in patients with insulinoma refractory and/or intolerant to diazoxide or with a high risk of fluid retention.

Abstract
OBJECTIVE Recommendations to obtain the best bonding to silica-based ceramics are to prepare its surface by hydrofluoric-acid HF etching and regular application of a silane. This study investigated how the HF-etching following by ultrasonic water bath cleaning (recommended protocol to improve the bonding with a composite resin), modifies the surface chemistry of a lithium disilicate glass-ceramic and impacts the chemical bonding with silane. METHODS Lithium disilicate glass-ceramic discs (IPS Emax Press, Ivoclar Vivadent) were mirror polished, etched with 9% HF for 20 s and rinsed 1 min under water. Two post-etching cleaning were compared: (1) no additional cleaning and (2) immersion in water ultrasonic bath for 4 min. Morphology evolution of the surfaces was carried out by scanning electron microscopy. Chemical changes were studied using X-ray Photoelectron Spectroscopy and Nano Auger Electron Spectroscopy analyses. Identification of the compounds formed with fluorine was based on by High Resolution Transmission Tlectronic Microscopy . RESULTS Residues left on the surface of the discs after etching, the fluorine salts, were eliminated after the ultrasonic bath cleaning. However, analyses showed presence of fluorine on the lithium disilicate needles associated among others with the lithium. HR-TEM validates the presence of Li2SiF6 crystallized phased. A mechanism to explain silane bonding when Li2SiF6 phase is formed on the Li2Si2O5 needles, is proposed. SIGNIFICANCE HF-etching leads to the formation of lithium and fluorine contain LiSi2F6 nano-precipitates on the Li2Si2O5 needles which helps to improve the bonding with silane.

Abstract
Myelolipoma is a rare mesenchymal tumor consisting of adipose tissue and hematopoietic cells. Found usually in the adrenal region, however, few cases have been reported in extra-adrenal regions, most frequently in the presacral region. It is important to recognize such tumor, as it can attain massive size and causes pressure symptoms, and needs to be differentiated from malignant tumors, including liposarcomas. Although CT and MRI can suggest a diagnosis of myelolipoma, these are not conclusive. The hematopoietic cells are enhanced by a Tc-albumin nanocolloid scintigraphy and help to distinguish myolipoma from other entities.

Abstract
La crise sanitaire Covid-19 a obligé les Samu–Smur à adapter leurs organisations au jour le jour. La régulation a dû trouver des réponses spécifiques aux types d’appels, au plan quantitatif et qualitatif. En lien avec la médecine générale et les recommandations ministérielles, le Samu devait être le garant d’une juste orientation des patients vers les services hospitaliers. Le Samu 94 et la faculté de santé de Créteil ont créé une cellule dédiée aux établissements d’hébergement des personnes âgées dépendantes, accessible via une ligne spécialisée du Samu–centre 15, offrant 24 heures/24 l’accès à des compétences gériatriques et conseils divers, véritable lien ville–hôpital. Le retour d’expérience montre que cette cellule est une des facettes, dans le domaine de la gériatrie, de ce qu’est le concept de service d’accès aux soins (SAS) et qu’il ne faut pas attendre un rebond de crise pour en consolider les fondements.

Abstract
OBJECTIVE This study investigated how European first responders and hospital personnel, along with CBRN experts, approach an overwhelming surge situation after a chemical incident. Surge capacity and capability bottlenecks were discussed. MATERIALS AND METHODS Two chemical warfare agent (CWA) scenarios were developed: in the first, a nerve agent was released indoors; in the second, there was an outdoor explosion containing a blister agent. CBRNE experts, first responders and hospital specialists from across Europe participated in a two-day table-top exercise to discuss pre-hospital and hospital CBRNE preparedness, triage, surge capacity and communication issues. This was followed by a medical response exercise at a level 2 Emergency Department in Italy. RESULTS Several surge capacity challenges and lessons were identified. Critical resources were rapidly exhausted and sourcing from national/international medical stockpiles was not feasible in the time critical scenarios. Secondary contamination in the blister agent scenario was considered plausible and hospitals are currently unprepared for this situation. The medical response exercise highlighted further training needs. CONCLUSIONS The majority of the lessons are not new and have been reported in North American studies. However, this study is the first to describe these CWA challenges from a European perspective. Medical facilities across the region should consider these lessons to evaluate and improve their surge capacity, capability and response.

Abstract
Portal hyperperfusion and "dearterialization" of the liver remnant are the main pathogenic mechanisms for Small For Size syndrome (SFSS). Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) induces rapid remnant hypertrophy. We hypothesized a similar increase in portal pressure/flow into the future liver remnant in ALPPS and SFSS-setting hepatectomies. In a rodent model, ALPPS was compared to SFSS-setting hepatectomy. We assessed mortality, remnant hypertrophy, hepatocyte proliferation, portal and hepatic artery flow, hypoxia-induced response, and liver sinusoidal morphology. SFSS-hepatectomy rats were subjected to local (hepatic artery ligation) or systemic (Dimethyloxalylglycine) hypoxia. ALLPS prevented mortality in SFSS-setting hepatectomies. Portal hyperperfusion per liver mass was similar in ALLPS and SFSS. Compared to SFSS, efficient arterial perfusion of the remnant was significantly lower in ALPPS causing pronounced hypoxia confirmed by pimonidazole immunostaining, activation of hypoxia sensors and upregulation of neo-angiogenic genes. Liver sinusoids, larger in ALPPS, collapsed in SFSS. Induction of hypoxia in SFSS reduced mortality. Hypoxia had no impact on hepatocyte proliferation but contributed to the integrity of sinusoidal morphology. ALPPS hemodynamically differ from SFSS by a much lower arterial flow in ALPPS's FLR. We show that the ensuing hypoxic response is essential for the function of the regenerating liver by preserving sinusoidal morphology.

Abstract
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) allows extended hepatectomy in patients with an extremely small future liver remnant (FLR). Current rodent models of ALPPS do not include resection resulting in insufficient-for-survival FLR, or they do incorporate liver mass reduction prior to ALPPS. Differences in FLR volume and surgical procedures could bias our understanding of physiological and hemodynamic mechanisms. We aimed to establish a rat ALPPS model with minimal FLR without prior parenchymal resection. In rodents, the left median lobe (LML) represents 10% of total liver. Partial hepatectomy (PHx) sparing LML and pericaval parenchyma represents our reference 87% resection. The first step in the procedure is either portal vein ligation (PVL) corresponding to ligation of all but the LML portal branches, or PVL with transection between the left and right median lobe segments (PVLT), and is defined as ALPPS stage-1. Second, ligated lobes were removed: PVL-PHx represents a conventional 2-stage hepatectomy, while PVLT followed by PHx is a strict reproduction of human ALPPS. In Group A, liver hypertrophy was analyzed after PVL (n = 38), PVLT (n = 47), T (n = 10), and sham (n = 10); In group B, mortality and FLR hypertrophy was assessed after PHx (n = 42), Sham-PHx (n = 6), PVL-PHx (n = 37), and PVLT-PHx (n = 45). In group A, PVLT induced rapid FLR hypertrophy compared to PVL (p < 0,05). Hepatocyte proliferation was higher in PVLT remnants (p < 0,05). In group B, PHx had a 5-day mortality rate of 84%. Sham operation prior to PHx did not improve survival (p = 0.23). In both groups, major fatalities occurred within 48 h after resection. PVL or PVLT prior to PHx reduced mortality to 33.3% (p = 0,007) or 25% (p = 0.0002) respectively, with no difference between the 2 two-stage procedures (p = 0.6). 7-day FLR hypertrophy was higher after the PVLT-PHx compared to PVL-PHx and PHx (p = 0.024). Our model reproduces human ALPPS with FLR that is insufficient for survival without liver resection prior to the stage-1 procedure. It offers an appropriate model for analyzing the mechanisms driving survival rescue and increased hypertrophy.

Abstract
AIM To assess the role of laparoscopic ultrasound (LUS) as a substitute for intraoperative cholangiography (IOC) during cholecystectomy.
METHODS We present a MEDLINE and PubMed literature search, having used the key-words “laparoscopic intraoperative ultrasound” and “laparoscopic cholecystectomy”. All relevant English language publications from 2000 to 2016 were identified, with data extracted for the role of LUS in the anatomical delineation of the biliary tract, detection of common bile duct stones (CBDS), prevention or early detection of biliary duct injury (BDI), and incidental findings during laparoscopic cholecystectomy. Data for the role of LUS vs IOC in complex situations (i.e., inflammatory disease/fibrosis) were specifically analyzed.
RESULTS We report data from eighteen reports, 13 prospective non-randomized trials, 5 retrospective trials, and two meta-analyses assessing diagnostic accuracy, with one analysis also assessing costs, duration of the examination, and anatomical mapping. Overall, LUS was shown to provide highly sensitive mapping of the extra-pancreatic biliary anatomy in 92%-100% of patients, with more difficulty encountered in delineation of the intra-pancreatic segment of the biliary tract (73.8%-98%). Identification of vascular and biliary variations has been documented in two studies. Although inflammatory disease hampered accuracy, LUS was still advantageous vs IOC in patients with obscured anatomy. LUS can be performed before any dissection and repeated at will to guide the surgeon especially when hilar mapping is difficult due to fibrosis and inflammation. In two studies LUS prevented conversion in 91% of patients with difficult scenarios. Considering CBDS detection, LUS sensitivity and specificity were 76%-100% and 96.2%-100%, respectively. LUS allowed the diagnosis/treatment of incidental findings of adjacent organs. No valuable data for BDI prevention or detection could be retrieved, even if no BDI was documented in the reports analyzed. Literature analysis proved LUS as a safe, quick, non-irradiating, cost-effective technique, which is comparatively well known although largely under-utilized, probably due to the perception of a difficult learning curve.
CONCLUSION We highlight the advantages and limitations of laparoscopic ultrasound during cholecystectomy, and underline its value in difficult scenarios when the anatomy is obscured.

Abstract
In the present work, the influence of external cooling on the temperature rise in the tooth pulpal chamber during femtosecond laser ablation was investigated. The influence of the cooling method on the morphology and constitution of the laser-treated surfaces was studied as well. The ablation experiments were performed on dentin specimens using an Yb:KYW chirped-pulse-regenerative amplification laser system (560 fs, 1030 nm). Cavities were created by scanning the specimens at a velocity of 5 mm/s while pulsing the stationary laser beam at 1 kHz and with fluences in the range of 2-14 J/cm2. The experiments were performed in air and with surface cooling by a lateral air jet and by a combination of an air jet and water irrigation. The temperature in the pulpal chamber of the tooth was measured during the laser experiments. The ablation surfaces were characterized by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. The temperature rise reached 17.5 °C for the treatments performed with 14 J/cm2 and without cooling, which was reduced to 10.8 ± 1.0 and 6.6 ± 2.3 °C with forced air cooling and water cooling, respectively, without significant reduction of the ablation rate. The ablation surfaces were covered by ablation debris and resolidified droplets containing mainly amorphous calcium phosphate, but the amount of redeposited debris was much lower for the water-cooled specimens. The redeposited debris could be removed by ultrasonication, revealing that the structure and constitution of the tissue remained essentially unaltered. The present results show that water cooling is mandatory for the femtosecond laser treatment of dentin, in particular, when high fluences and high pulse repetition rates are used to achieve high material removal rates.

Abstract
BACKGROUND Splenectomy for massive splenomegaly (spleen weight more than 1·5 kg) is commonly believed to be hazardous and to provide poor palliation. The aim of this cohort study was to investigate these issues and examine the many definitions of massive splenomegaly to see whether a better tool might be proposed for preoperative evaluation of these patients. METHODS Morbidity and long-term outcomes were assessed in consecutive patients. Relief of pressure-volume-related symptoms and sustainable independence from transfusion in patients were used to ascertain the impact of splenectomy. RESULTS Splenectomy was performed in 56 patients, mainly for non-Hodgkin's lymphoma and myeloproliferative diseases. Median spleen weight was 2·3 (range 1·5-6·0) kg. Mortality at 180 days was zero, and the postoperative complication rate was 25 per cent (17 complications in 14 patients). At 2 years, relief of pain was maintained in 33 of 34 patients, with sustained independence from transfusion in 15 of 19 patients with anaemia and nine of 11 with thrombocytopenia. Spleen weight correlated negatively with BMI (P = 0·036). CONCLUSION Splenectomy for massive splenomegaly is safe and provides effective palliation. Provisional cut-off points relating to spleen size and BMI help to identify patients benefiting from a splenectomy, even those in a critical state.

Abstract
Typical presentation of subacute thyroiditis (SAT) is an anterior neck pain radiating up to the jaw and ear, often associated with asthenia and fever. Biology shows hyperthyroidism and inflammation. The thyroid uptake is low at scintigraphy. However, the clinical presentation of SAT may be misleading. We report two cases of SAT whose initial manifestation was a painful thyroid nodule suspected of malignancy. In both cases, ultrasound feature was a heterogeneous, hypoechoic, ill-defined area with a low vascularization on colour Doppler. These areas were interpreted by radiologist as nodules. Surgery was then considered. Such a presentation should be known by clinicians to prevent unnecessary surgery.

Abstract
Abstract
Background
The benefit of neoadjuvant chemotherapy (NCT) for early-stage oesophageal cancer is unknown. The aim of this study was to assess whether NCT improves the outcome of patients with stage I or II disease.
Methods
Data were collected from 30 European centres from 2000 to 2010. Patients who received NCT for stage I or II oesophageal cancer were compared with patients who underwent primary surgery with regard to postoperative morbidity, mortality, and overall and disease-free survival. Propensity score matching was used to adjust for differences in baseline characteristics.
Results
Of 1173 patients recruited (181 NCT, 992 primary surgery), 651 (55·5 per cent) had clinical stage I disease and 522 (44·5 per cent) had stage II disease. Comparisons of the NCT and primary surgery groups in the matched population (181 patients in each group) revealed in-hospital mortality rates of 4·4 and 5·5 per cent respectively (P = 0·660), R0 resection rates of 91·7 and 86·7 per cent (P = 0·338), 5-year overall survival rates of 47·7 and 38·6 per cent (hazard ratio (HR) 0·68, 95 per cent c.i. 0·49 to 0·93; P = 0·016), and 5-year disease-free survival rates of 44·9 and 36·1 per cent (HR 0·68, 0·50 to 0·93; P = 0·017).
Conclusion
NCT was associated with better overall and disease-free survival in patients with stage I or II oesophageal cancer, without increasing postoperative morbidity.

Abstract
OBJECTIVE We raised the question of a possible relationship in Belgium between the occurrence of papillary thyroid carcinoma (PTC) and age of children (<15 years) at the time of the Chernobyl nuclear plant accident in April 1986. SETTING Referral university centre for endocrine surgery. MATERIAL AND METHODS Thirty-year prospective study of the experience of a surgical team with PTC since the Chernobyl accident, taken out of 2349 patients operated on for any thyroid lesions from April 1986 to April 2015, comparing the incidence of PTC by age groups. MAIN OUTCOME MEASUREMENT Comparison of PTC incidence in patients >15 years (group A) and children <15 years (group B) in April 1986. RESULTS Out of a total of 2349 patients having undergone thyroid surgery for all types of lesions during 30 year after Chernobyl and born before April 1986, 2164 were >15 years of age at the time of the nuclear accident (group A) and 175 developed PTC (8.1%) compared to 36 PTC (19.5%) that occurred in 185 children <15 years of age (group B) in April 1986 (p < 0.001). CONCLUSIONS Radiation exposure affected residents of countries (including Belgium) well beyond Ukraine and Belarus. This was demonstrated by a 1990 meteorological report. Over 30 years, there has been a persistent higher incidence of PTC among Belgian children below the age of 15 years at the time of the Chernobyl accident. This relationship with age has even been strengthened by the implementation of more sophisticated immunohistochemical biomarkers diagnostic technology since April 2011.

Abstract
Abstract. In the framework of the interdisciplinary FORBIO Climate research project, the Royal Meteorological Institute of Belgium is in charge of providing high resolution gridded past climate data (i.e. temperature and precipitation). This climate data set will be linked to the measurements on seedlings, saplings and mature trees to assess the effects of climate variation on tree performance. This paper explains how the gridded daily temperature (minimum and maximum) data set was generated from a consistent station network between 1980 and 2013. After station selection, data quality control procedures were developed and applied to the station records to ensure that only valid measurements will be involved in the gridding process. Thereafter, the set of unevenly distributed validated temperature data was interpolated on a 4 km × 4 km regular grid over Belgium. The performance of different interpolation methods has been assessed. The method of kriging with external drift using correlation between temperature and altitude gave the most relevant results.

Abstract
Abstract. Investigations are conducted to best estimate precipitation climate maps over Belgium from daily observations available for the period 1981–2010. Several mapping approaches are compared in a cross-validation exercise. These approaches differ by several aspects and in particular by the order in which the temporal aggregation (i.e. computation of climate mean values from daily data) and spatial interpolation steps are performed, and by the integration of ancillary information in the spatial interpolation method. The selected approach is used to derive a large panel of climate maps. In particular, the main spatio-temporal features of the annual cycle of rainfall in Belgium are extracted by principal component analysis (PCA).

Abstract
Abstract. Soil temperatures at various depths are unique parameters useful to describe both the surface energy processes and regional environmental and climate conditions. To provide soil temperature observation in different regions across Belgium for agricultural management as well as for climate research, soil temperatures are recorded in 13 of the 20 automated weather stations operated by the Royal Meteorological Institute (RMI) of Belgium. At each station, soil temperature can be measured at up to 5 different depths (from 5 to 100 cm) in addition to the bare soil and grass temperature records. Although many methods have been developed to identify erroneous air temperatures, little attention has been paid to quality control of soil temperature data. This contribution describes the newly developed semi-automatic quality control of 10-min soil temperatures data at RMI.

Abstract
BACKGROUND In 2006, bevacizumab, a targeted therapy agent was combined with FOLFIRI for the firstline treatment of patients with unresectable metastatic colorectal cancer. METHODS/RESULTS A study on a homogenous series of 111 patients from the Brittany and Pays de la Loire areas who received bevacizumab-FOLFIRI as first-line treatment in 2006 showed the following results: 51 responses, 29 stabilisations, 21 progressions and 10 cases of toxicity prior to assessment. Median overall survival (OS) was 25.1 months and median progression-free survival was 10.2 months. Surgery secondary to treatment tripled median OS which reached 59.2 months in resected patients versus 18.8 months in unresected patients. Comparison of patients aged more or less than 70 years showed no differences in terms of benefits or risks. CONCLUSION Bevacizumab-FOLFIRI could be administered as part of a routine care protocol to elderly patients previously evaluated by a geriatric assessment and validated by a multidisciplinary staff.

Abstract
BACKGROUND A variety of anti-adhesive composite mesh products have become available to use inside the peritoneal cavity. However, reimbursement of these meshes by the Belgian Governemental Health Agency (RIZIV/INAMI) can only be obtained after conducting a prospective study with at least one year of clinical follow-up. This -Belgian multicentric cohort study evaluated the experience with the use of Proceed®-mesh in laparoscopic ventral hernia repair. METHODS During a 25 month period 210 adult patients underwent a laparoscopic primary or incisional hernia repair using an intra-abdominal placement of Proceed®-mesh. According to RIZIV/INAMI criteria recurrence rate after 1 year was the primary objective, while postoperative morbidity, including seroma formation, wound and mesh infections, quality of life and recurrences after 2 years were evaluated as secondary endpoints (NCT00572962). RESULTS In total 97 primary ventral and 103 incisional hernias were repaired, of which 28 (13%) were recurrent. There were no conversions to open repair, no enterotomies, no mesh infections and no mortality. One year cumulative follow-up showed 10 recurrences (n = 192, 5.2%) and chronic discomfort or pain in 4.7% of the patients. Quality of life could not be analyzed due to incomplete data set. CONCLUSIONS More than 5 years after introduction of this mesh to the market, this prospective multicentric study documents a favorable experience with the Proceed mesh in laparoscopic ventral hernia repair. However, it remains to be discussed whether reimbursement of these meshes in Belgium should be limited to the current strict criteria and therefore can only be obtained after at least 3-4 years of clinical data gathering and necessary follow-up.

Abstract
PURPOSE We studied the predictive value of [(18) F]fluorodeoxyglucose-positron emission tomography ((18)FDG-PET) for assessing disease-free (DFS) and overall survival (OS) in esophageal and esophagogastric junction cancer. MATERIALS AND METHODS A literature search (PUBMED/MEDLINE, EMBASE, Cochrane) was performed to identify full papers with (18)FDG-PET and survival data, using indexing terms and free text words. Studies with >10 patients with locally advanced esophageal cancer, presenting sequential or at least one post-adjuvant treatment (18)FDG-PET data and Kaplan-Meier survival curves with >6 months median follow-up period were included. We performed a meta-analysis for DFS and OS using the hazard ratio (HRs) as outcome measure. Sources of heterogeneity study were also explored. RESULTS We identified 26 eligible studies including a total of 1,544 patients (average age 62 years, 82% males). The TNM distribution was as follows: stage I 7%, II 24%, III 53% and IV 15%. The pooled HRs for complete metabolic response versus no response were 0.51 for OS (95% CI, 0.4-0.64; P < 0.00001) and 0.47 for DFS (95% CI, 0.38-0.57; P < 0.00001), respectively. No statistical heterogeneity was present. To explore sources of clinical heterogeneity, we also realised subgroup and regression analyses. Taken into account the moderate correlation between OS and DFS (ρ = 0.54), we used joint bivariate random regression model. These analyses did not show a statistically significant impact of study characteristics and PET modalities on the pooled outcome estimates. CONCLUSION Despite methodological and clinical heterogeneity, metabolic response on (18)FDG-PET is a significant predictor of long-term survival data.

Abstract
PURPOSE Resveratrol inhibits lipid accumulation but suffers from limited bioavailability. The anti-depressive agent phenelzine limits adipogenesis in various models of cultured preadipocytes, and this hydrazine derivative also inhibits de novo lipogenesis in mature adipocytes. It was therefore tested whether resveratrol effects on adiposity reduction and glucose tolerance improvement could be reinforced by co-administration with phenelzine. METHODS Mice fed a very-high-fat diet (VHFD, 60% calories as fat) were subjected to drinking solution containing low dose of resveratrol (0.003%) and/or 0.02% phenelzine for 12 weeks. Body fat content, glucose tolerance, food and water consumption were checked during treatment while fat depot mass was determined at the end of supplementation. Direct influence of the agents on lipogenesis and glucose uptake was tested in adipocytes. RESULTS Epididymal fat depots were reduced in mice drinking phenelzine alone or with resveratrol. No limitation of body weight gain or body fat content was observed in the groups drinking resveratrol or phenelzine, separately or in combination. The altered glucose tolerance and the increased fat body composition of VHFD-fed mice were not reversed by resveratrol and/or phenelzine. Such lack of potentiation between resveratrol and phenelzine prompted us to verify in vitro their direct effects on mouse adipocytes. Both molecules inhibited de novo lipogenesis, but did not potentiate each other at 10 or 100 μM. Only resveratrol inhibited hexose uptake in a manner that was not improved by phenelzine. CONCLUSIONS Phenelzine has no interest to be combined with low doses of resveratrol for treating/preventing obesity, when considering the VHFD mouse model.

Abstract
BACKGROUND There are few reports on the oncological quality of resection and outcome after laparoscopic versus open total mesorectal excision (TME) for rectal cancer in everyday surgical practice. METHODS Between January 2006 and October 2011, data for patients with mid or low rectal adenocarcinoma who underwent elective TME were recorded in the PROCARE database. A multivariable model and the propensity score as a co-variable in Cox or logistic regression models were used for adjustment of differences in patient mix and non-random assignment of surgical approach. RESULTS Data for 2660 patients from 82 hospitals were recorded. Implementation of laparoscopic TME was highly variable. The oncological quality of resection was similar in the laparoscopic and the open group: incomplete mesorectal excision in 13·2 and 11·4 per cent respectively, circumferential resection margin positivity in 18·1 per cent, and a median of 11 lymph nodes examined per specimen in both groups. The hazard ratio for survival after laparoscopic versus open TME was 1·05 (95 per cent confidence interval 0·88 to 1·24) after correction for differences in patient mix, and 1·06 (0·89 to 1·25) after correction for the propensity score. The definitive colostomy rate was similar in the two groups: 31·0 per cent after open and 31·4 per cent after laparoscopic TME. Postoperative morbidity was lower and length of stay was shorter after laparoscopic TME compared with open TME. Survival was not negatively affected by converted laparoscopic resection, whereas postoperative morbidity, mortality and length of stay after converted laparoscopy were comparable with those after open TME. CONCLUSION Oncological outcome is comparable after laparoscopic and open TME in everyday surgical practice.

Abstract
AIMS/HYPOTHESIS Lysophosphatidic acid (LPA) is a lipid mediator produced by adipocytes that acts via specific G-protein-coupled receptors; its synthesis is modulated in obesity. We previously reported that reducing adipocyte LPA production in high-fat diet (HFD)-fed obese mice is associated with improved glucose tolerance, suggesting a negative impact of LPA on glucose homeostasis. Here, our aim was to test this hypothesis. METHODS First, glucose tolerance and plasma insulin were assessed after acute (30 min) injection of LPA (50 mg/kg) or of the LPA1/LPA3 receptor antagonist Ki16425 (5 mg kg(-1) day(-1), i.p.) in non-obese mice fed a normal diet (ND) and in obese/prediabetic (defined as glucose-intolerant) HFD mice. Glucose and insulin tolerance, pancreas morphology, glycogen storage, glucose oxidation and glucose transport were then studied after chronic treatment (3 weeks) of HFD mice with Ki16425. RESULTS In ND and HFD mice, LPA acutely impaired glucose tolerance by inhibiting glucose-induced insulin secretion. These effects were blocked by pre-injection of Ki16425 (5 mg/kg, i.p.). Inhibition of glucose-induced insulin secretion by LPA also occurred in isolated mouse islets. Plasma LPA was higher in HFD mice than in ND mice and Ki16425 transiently improved glucose tolerance. The beneficial effect of Ki16425 became permanent after chronic treatment and was associated with increased pancreatic islet mass and higher fasting insulinaemia. Chronic treatment with Ki16425 also improved insulin tolerance and increased liver glycogen storage and basal glucose use in skeletal muscle. CONCLUSIONS/INTERPRETATION Exogenous and endogenous LPA exerts a deleterious effect on glucose disposal through a reduction of plasma insulin; pharmacological blockade of LPA receptors improves glucose homeostasis in obese/prediabetic mice.

Abstract
BACKGROUND In this prospective, randomized controlled trial, our objective was to assess both the clinical and radiographic effect of recombinant human bone morphogenetic protein-2 (rhBMP-2) in patients treated with an instrumented single-level posterior lumbar interbody arthrodesis with polyetheretherketone cages. METHODS Forty patients were randomized with a 1:1 ratio. Two patients who had a two-level arthrodesis (L4-L5 and L5-S1) were excluded. Patients completed the Oswestry Disability Index, the Short Form-36, and the visual analog scale preoperatively and postoperatively at three, six, twelve, and twenty-four months. Computed tomography scans with coronal and sagittal reconstructions were made at three, six, and twelve months postoperatively. Interbody arthrodesis was performed using polyetheretherketone cages, which were filled with 8 mg of rhBMP-2 in the study group and 2.5 mL of autologous bone in the control group. RESULTS Baseline demographic data showed no significant difference between groups, except for the body mass index, which was higher in the study group (p = 0.032). There were no significant differences in the clinical results (visual analog scale, Oswestry Disability Index, and Short Form-36) between the groups at each postoperative visit. At three months, end-plate resorption was noted around the cages filled with rhBMP-2 in all patients in the study group. No cage migration or subsidence was observed. Bridging trabecular bone scale scores and bone density measures were significantly lower in the study group. Osteolysis and ectopic bone formation occurred in seven of nineteen patients in the study group and did not occur in the control group. This did not result in radicular symptoms within the time span of this study. At one year, computed tomography scans showed osseous healing in all patients. There were no revision procedures. CONCLUSIONS This trial showed no clinical difference when rhBMP-2 was used in posterior lumbar interbody arthrodesis compared with autologous bone. On computed tomography scans, fusion was equally achieved, but trabecular bone formation occurred at a slower rate and interbody bone density was lower within the first year after surgery when rhBMP-2 was used. End-plate resorption, osteolysis, and ectopic bone formation were frequently noted in the rhBMP-2 group.

Abstract
BACKGROUND Postoperative pancreatic fistula is the leading cause of death and morbidity after pancreaticoduodenectomy. However, the best reconstruction method to reduce occurrence of fistula is debated. We did a multicentre, randomised superiority trial to compare the outcomes of different reconstructive techniques in patients undergoing pancreaticoduodenectomy for pancreatic or periampullary tumours. METHODS Patients aged 18-85 years with confirmed or suspected neoplasms of the pancreas, distal bile duct, ampulla vateri, duodenum, or periampullary tumours were eligible for inclusion. An internet-based platform was used to randomly assign patients to either pancreaticojejunostomy or pancreaticogastrostomy as reconstruction after pancreaticoduodenectomy, using permuted blocks with six patients per block. Within each centre the randomisation was stratified on the pancreatic duct diameter (≤3 mm vs >3 mm) measured at the time of surgery. The primary endpoint was the occurrence of clinical postoperative pancreatic fistula (grade B or C) as defined by the International Study Group on Pancreatic Fistula. The study was not masked and analyses were done by intention to treat. Patient follow-up was closed 2 months after discharge from the hospital. This study is registered with ClinicalTrials.gov, number NCT00830778. FINDINGS Between June, 2009, and August, 2012, we randomly allocated 167 patients to receive pancreaticojejunostomy and 162 to receive pancreaticogastrostomy. 33 (19.8%) patients in the pancreaticojejunostomy group and 13 (8.0%) in the pancreaticogastrostomy group had clinical postoperative pancreatic fistula (OR 2.86, 95% CI 1.38-6.17; p=0.002). The overall incidence of postoperative complications did not differ significantly between the groups (99 in the pancreaticojejunostomy group vs 100 in the pancreaticogastrostomy group), although more events in the pancreaticojejunostomy group were of grade ≥3a than in the pancreaticogastrostomy group (39 vs 35). INTERPRETATION In patients undergoing pancreaticoduodenectomy for pancreatic head or periampullary tumours, pancreaticogastrostomy is more efficient than pancreaticojejunostomy in reducing the incidence of postoperative pancreatic fistula.

Abstract
Abstract. Sunshine duration was historically the traditional parameter to quantify solar radiation. In the present study, we propose to benefit from the measurements made with Campbell-Stokes recorders at 18 sites in Belgium and Luxembourg to generate maps of daily sunshine duration for the period 1995–2005. In order to provide maps with the highest degree of confidence as possible, ancillary data of high spatial resolution derived from Meteosat satellites images are used within the mapping process. Different methods combining in situ sunshine duration measurements and Meteosat-derived data are evaluated. The best performing method is then used to compile a dataset of gridded daily sunshine duration data over Belgium and Luxembourg. The 1995–2005 sunshine duration climate map is finally provided. Various areal mean values are computed and discussed.

Abstract
Abstract. Appropriate information on solar resources is very important for a variety of technological areas. Based on the potential of retrieving global horizontal irradiance from satellite data, an enhanced version of the Heliosat-2 method has been implemented at the Royal Meteorological Institute of Belgium to estimate surface solar irradiance over Belgium from Meteosat Second Generation at the SEVIRI spatial and temporal resolution. In this contribution, sensitivity of our retrieval scheme to surface albedo, atmospheric aerosol and water vapor contents is investigated. Results indicate that while the use of real-time information instead of climatological values can help to reduce to some extent the RMS error between satellite-retrieved and ground-measured solar irradiance, only the correction of the satellite-derived data with in situ measurements allows to significantly reduce the overall model bias.

Abstract
Abstract. In the '90s, the Royal Meteorological Institute (RMI) of Belgium started to replace its conventional ''manual'' meteorological network by automated weather stations (AWSs). The meteorological measurement network is now fully automated. RMI counts 18 AWSs that made automated observations centrally available in our headquarters in Uccle, Brussels to internal as well as external users. Due to the large increase in the data amount associated with the automation, quality assurance (QA) procedures are being automated. However, human operators continue to play an essential role in the data validation processes. This contribution describes our newly developed semi-automatic quality control (QC) of 10-min air temperature data. After an existence test, the data are checked for limits consistency, temporal consistency and spatial consistency. At the end of these automated checks, a decision algorithm attributes a flag to each particular data. Each day the QC staff analyzes the preceding day observations in the light of the quality flags assigned by automated QA procedures during the night. It is the human decision whether or not a value is accepted.
