Abstract
PURPOSE/OBJECTIVE(S) To determine the best time interval between neoadjuvant radiation therapy (RT) and surgery that is associated with the highest rate of complete pathological response (pCR) and evaluate its impact on overall survival (OS) for locally advanced rectal adenocarcinoma. We hypothesize that the longer interval the higher pCR and a higher pCR is associated with a higher OS. MATERIALS/METHODS The National Cancer Database (NCDB) was used to extract data on patients diagnosed with stage II and III adenocarcinoma of the anus, rectum, or rectosigmoid between 2004-2019 and who had ≤ 24 weeks' time interval between neoadjuvant RT and surgery. Multivariable logistic regression analysis was used to determine factors associated with achieving pCR and odds ratios (OR) were reported as a measure of association between the covariates of interest and the outcome of achieving pCR. Multivariable Cox regression analysis was conducted to estimate hazard ratios (HR) and their associated 95% confidence intervals. The multivariable analyses were adjusted for age at diagnosis, sex, race, income, education, facility type, insurance status, comorbidity score, place of living, chemotherapy's sequence with surgery and RT, and year of diagnosis. RESULTS Among 28,656 patients, 4,455 (15.6%) achieved pCR. In the multivariable logistic regression analysis, patients who received surgery between 5-8 weeks, 9-12 weeks, 13-16 weeks, 17-20 weeks, or 21-24 weeks after the completion of RT were more likely to achieve pCR compared to < = 4 weeks (ORs: 1.63, 2.16, 1.82, 1.73, 1.75, respectively, p<0.001 for all) with OR being the highest for the 9-12 weeks interval. In the multivariable Cox regression analysis, patients who achieved pCR had comparable OS regardless of when the surgery took place between < = 4 to 24 weeks after completing RT compared to < = 4 weeks after RT. Among patients who did not achieve pCR, OS was only similar if surgery was received between 5-8 weeks or 9-12 weeks after RT compared to < = 4 weeks after RT (HR: 0.90, p = 0.19 and HR: 1.02, p = 0.78 respectively). However, surgery between 13-16 weeks after RT, 71-20 weeks or 21-24 weeks after RT was associated with worse OS compared to < = 4 weeks after RT (HRs: 1.30, 1.67, 1.79, respectively, p<0.01). CONCLUSION In the current study, we found that among patients who achieve pCR, OS does not depend on the time interval between the completion of RT and receipt of surgery, while among patients who do not achieve pCR, delaying surgery >12 weeks is associated with reduced OS. An interval of 9-12 weeks was the best optimal time as it was associated with the highest OR of achieving pCR and better OS compared to other interval times.

Abstract
Summary Background.In the diagnostic work up of allergy, determining allergen component-specific immunoglobulin E (IgE) is important for diagnosis, prognosis and choice of treatment. The purpose of this study was to evaluate the performance of the immunoblotting assay (Euroline) in detection of IgE antibodies against timothy grass and birch pollen allergen components compared to fluorescent enzyme assay (ImmunoCAP, Phadia 250). Methods. A total of 128 serum samples from patients allergic to timothy grass and birch pollen were analysed. The levels of IgE antibodies to timothy grass and birch pollen were measured using Euroline DPA-Dx pollen 1 and ImmunoCAP assay. The two methods were then compared on binary (positive vs negative), semi-quantitative (IgE classes) and quantitative (concentration) levels. The two methods were also compared to results from skin prick testing. Results. The Euroline method showed a positive percentage agreement of 93% and negative percentage agreement of 94% with an overall accuracy of 94% when compared to ImmunoCAP. Kappa analysis showed moderate strength of agreement between the methods in determining IgE classes for 7/11 components tested. All components showed a positive correlation when analysed using Spearman's rank correlation. Conclusions. Overall, we found that there is good correlation between the Euroline and ImmunoCAP methods in measuring IgE sensitization.

Abstract
Summary Background. Patients show varied results to allergen immunotherapy (AIT. The reason for this variability is unclear. Objective. To describe the relationship between AIT efficacy and demographic characteristics, as well as pre-treatment plasma levels of specific IgE-antibodies to grass and birch pollen. Methods. A retrospective study was performed based on medical records of 128 patients who received AIT. The patients completed a questionnaire and pre-AIT plasma levels of allergen-specific IgE to grass and birch pollen were measured using EUROLINE DPA-Dx pollen 1 method. Results. Seventy percent of patients classified their allergic symptoms as less severe after AIT. Twenty-seven percent had received AIT targeting only grass pollen, 19% targeting only birch pollen, and 55% targeting both grass and birch. A total of 35 different IgE profiles were found across our study population. On comparison of the demographic characteristics and concentration of allergen-specific IgE-antibodies, no statistically significant differences could be found.Conclusions. The majority of patients rated their allergic symptoms as less severe after AIT. No clear relationship could be demonstrated between pre-treatment allergen-specific IgE concentration, or demographic characteristics, and effect of AIT. There may be other factors underlying the different responses to AIT.

Abstract
The title mol-ecule, C17H26N2O, adopts an L-shaped conformation, with the straight n-decyl chain positioned nearly perpendicular to the di-hydro-benzimidazole moiety. The di-hydro-benzimidazole portion is not quite planar as there is a dihedral angle of 1.20 (6)° between the constituent planes. In the crystal, N-H⋯O hydrogen bonds form inversion dimers, which are connected into the three-dimensional structure by C-H⋯O hydrogen bonds and C-H⋯π(ring) inter-actions. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from H⋯H (75.9%), H⋯C/C⋯H (12.5%) and H⋯O/O⋯H (7.0%) inter-actions. Based on computational chemistry using the CE-B3LYP/6-31 G(d,p) energy model, C-H⋯O hydrogen bond energies are -74.9 (for N-H⋯O) and -42.7 (for C-H⋯O) kJ mol-1.

Abstract
INTRODUCTION Most studies of elderly-onset Crohn's disease [CD; diagnosed in patients aged 60 or over] have described a mild course. However, data on the natural history of perianal fistulising CD [pfCD] in this population are scarce. In a population-based cohort study, we described the prevalence, natural history, and treatment of pfCD in patients with elderly-onset CD vs patients with paediatric-onset CD. METHOD All patients diagnosed with CD at or after the age of 60 between 1988 and 2006, were included [n = 372]. Logistic regression, Cox models, and a nested case-control method were used to identify factors associated with pfCD. RESULTS A total of 34 elderly patients [9% of the 372] had pfCD at diagnosis. After a median follow-up of 6 years (interquartile range [IQR]: 3; 10), 59 patients [16%] had pfCD; the same prevalence [16%] was observed in paediatric-onset patients. At last follow-up, anal incontinence was more frequent in elderly patients with pfCD than in elderly patients without pfCD [22% vs 4%, respectively; p < 10-4]. Rectal CD at diagnosis was associated with pfCD: hazard ratio (95% confidence interval [CI] = 2.8 [1.6-5.0]). Although 37% of the patients received immunosuppressants and 17% received anti-tumour necrosis factor agents, 24% [14 out of 59] had a definitive stoma at last follow-up. CONCLUSION During the first 6 years of disease, the prevalence of pfCD was similar in elderly and paediatric patients. Rectal involvement was associated with the appearance of pfCD in elderly-onset patients. Around a quarter of patients with elderly-onset CD will have a stoma. Our results suggest that treatment with biologics should be evaluated in these patients.

Abstract
In the title mol-ecule, C24H21N5O·H2O, the di-hydro-benzo-diazole moiety is not quite planar, while the whole mol-ecule adopts a U-shaped conformation in which there is a close approach of the two benzyl groups. In the crystal, chains of alternating mol-ecules and lattice water extending along [201] are formed by O-HUncoordW⋯ODhyr and O-HUncoordW⋯NTrz (UncoordW = uncoordinated water, Dhyr = di-hydro and Trz = triazole) hydrogen bonds. The chains are connected into layers parallel to (010) by C-HTrz⋯OUncoordW hydrogen bonds with the di-hydro-benzo-diazole units in adjacent layers inter-calating to form head-to-tail π-stacking [centroid-to-centroid distance = 3.5694 (11) Å] inter-actions between them, which generates the overall three-dimensional structure. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from H⋯H (52.1%), H⋯C/C⋯H (23.8%) and O⋯H/H⋯O (11.2%) inter-actions. Hydrogen-bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Density functional theory (DFT) optimized structures at the B3LYP/ 6-311 G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.

Abstract
In the title mol-ecule, C11H10N2O, the di-hydro-benzimidazol-2-one moiety is essentially planar, with the prop-2-yn-1-yl substituent rotated well out of this plane. In the crystal, C-HMthy⋯π(ring) inter-actions and C-HProp⋯ODhyr (Mthy = methyl, Prop = prop-2-yn-1-yl and Dhyr = di-hydro) hydrogen bonds form corrugated layers parallel to (10), which are associated through additional C-HBnz⋯ODhyr (Bnz = benzene) hydrogen bonds and head-to-tail, slipped, π-stacking [centroid-to-centroid distance = 3.7712 (7) Å] inter-actions between di-hydro-benzimidazol-2-one moieties. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (44.1%), H⋯C/C⋯H (33.5%) and O⋯H/H⋯O (13.4%) inter-actions. Hydrogen-bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Computational chemistry calculations indicate that in the crystal, C-H⋯O hydrogen-bond energies are 46.8 and 32.5 (for C-HProp⋯ODhyr) and 20.2 (for C-HBnz⋯ODhyr) kJ mol-1. Density functional theory (DFT) optimized structures at the B3LYP/6-311 G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap.

Abstract
The title compound, C17H14N2O, is built up from the planar benzo-diazole unit linked to the benzyl and propynyl substituents. The substituents are rotated significantly out of the benzo-diazole plane, where the benzyl group is inclined by 68.91 (7)° to the benzo-diazole unit. In the crystal, the mol-ecules are linked via inter-molecular C-HBnzdzl⋯O and C-HBnzy⋯O (Bnzdzl = benzo-diazole and Bnzy = benz-yl) hydrogen bonds, enclosing R 4 4(27) ring motifs, into a network consisting of rectangular layers parallel to the bc plane which are also stacked along the a-axis direction being associated through C-H⋯π (ring) inter-actions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (43.6%), H⋯C/C⋯H (42.0%) and H⋯O/O⋯H (8.9%) inter-actions.

Abstract
In the title compound, C21H20N4O2, the intra-molecular C-H⋯O hydrogen-bonded benzo-diazo-lone moieties are planar to within 0.017 (1) and 0.026 (1) Å, and are oriented at a dihedral angle of 57.35 (3)°. In the crystal, two sets of inter-molecular C-H⋯O hydrogen bonds generate layers parallel to the bc plane. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (51.8%), H⋯C/C⋯H (30.7%) and H⋯O/O⋯H (11.2%) inter-actions.

Abstract
The self-avoiding walk on the square site-diluted correlated percolation lattice is considered. The Ising model is employed to realize the spatial correlations of the metric space. As a well-accepted result, the (generalized) Flory's mean-field relation is tested to measure the effect of correlation. After exploring a perturbative Fokker-Planck-like equation, we apply an enriched Rosenbluth Monte Carlo method to study the problem. To be more precise, the winding angle analysis is also performed from which the diffusivity parameter of Schramm-Loewner evolution theory (κ) is extracted. We find that at the critical Ising (host) system, the exponents are in agreement with Flory's approximation. For the off-critical Ising system, we find also a behavior for the fractal dimension of the walker trace in terms of the correlation length of the Ising system ξ(T), i.e., D_{F}^{SAW}(T)-D_{F}^{SAW}(T_{c})∼1/sqrt[ξ(T)].

Abstract
INTRODUCTION The Confusion Assessment Method (CAM) is a validated key tool in clinical practice and research programs to diagnose delirium and assess its severity. There is no validated French version of the CAM training manual and coding guide (Inouye SK). The aim of this study was to establish a consensual French version of the CAM and its manual. METHODS Cross-cultural adaptation to achieve equivalence between the original version and a French adapted version of the CAM manual. RESULTS A rigorous process was conducted including control of cultural adequacy of the tool's components, double forward and back translations, reconciliation, expert committee review (including bilingual translators with different nationalities, a linguist, highly qualified clinicians, methodologists) and pretesting. A consensual French version of the CAM was achieved. CONCLUSION Implementation of the CAM French version in daily clinical practice will enable optimal diagnosis of delirium diagnosis and enhance communication between health professionals in French speaking countries. Validity and psychometric properties are being tested in a French multicenter cohort, opening up new perspectives for improved quality of care and research programs in French speaking countries.

Abstract
OBJECTIVES Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period. METHODS Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification. RESULTS 1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/105 for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/105 (+126%; P<0.001) and for UC, from 1.6 to 4.1/105 (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC. CONCLUSIONS In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Abstract
BACKGROUND AND AIMS Data on extra-intestinal manifestations [EIM] and their impact on the disease course of ulcerative colitis [UC] in population-based cohorts are scarce, particularly in paediatric- and elderly-onset UC patients. The aims of this population-based study were to assess: 1] the occurrence of EIM in paediatric- and elderly-onset UC; 2] the factors associated with EIM; and 3] their impact on long-term disease outcome. METHODS Paediatric-onset [< 17 years at diagnosis] and elderly-onset UC patients [> 60 years at diagnosis] from a French prospective population-based registry [EPIMAD] were included. Data on EIM and other clinical factors at diagnosis and at maximal follow-up were collected. RESULTS In all, 158 paediatric- and 470 elderly-onset patients were included [median age at diagnosis 14.5 and 68.8 years, median follow-up 11.2 and 6.2 years, respectively]. EIM occurred in 8.9% of childhood- and 3% of elderly-onset patients at diagnosis and in 16.7% and 2.2% of individuals during follow-up [p < 0.01], respectively. The most frequent EIM was joint involvement [15.8% of paediatric onset and 2.6% of elderly-onset]. Presence of EIM at diagnosis was associated with more severe disease course [need for immunosuppressants or biologic therapy or colectomy] in both paediatric- and elderly-onset UC (hazard ratio [HR] = 2.0, 95% confidence interval [CI]: 1.0-4.2; and HR = 2.8, 0.9-7.9, respectively). Extensive colitis was another independent risk factor in both age groups. CONCLUSIONS Elderly-onset UC patients had lower risk of EIM either at diagnosis or during follow-up than paediatric-onset individuals. EIM at diagnosis predicted more severe disease outcome, including need for immunosuppressive or biologic therapy or surgery, in both paediatric- and elderly-onset UC.

Abstract
PURPOSE To determine survival in afatinib-treated patients after treatment with first-generation EGFR tyrosine kinase inhibitors (TKIs) and to study resistance mechanisms in afatinib-resistant tumors. METHODS Characteristics and survival of patients treated with afatinib after resistance to erlotinib or gefitinib in two large Dutch centers were collected. Whole exome sequencing (WES) and pathway analysis was performed on available pre- and post-afatinib tumor biopsies and normal tissue. RESULTS A total of 38 patients were treated with afatinib. T790M mutations were identified in 22/29 (76%) pre-afatinib treatment tumor samples. No difference in median progression-free-survival (2.8 months (95% CI 2.3-3.3) and 2.7 months (95% CI 0.9-4.6), p = 0.55) and median overall-survival (8.8 months (95% CI 4.2-13.4) and 3.6 months (95% CI 2.3-5.0), p = 0.14) were observed in T790M+ patients compared to T790M- mutations. Somatic mutations in TP53, ADAMTS2, CNN2 and multiple genes in the Wnt and PI3K-AKT pathway were observed in post-afatinib tumors of six afatinib-responding and in one non-responding patient. No new EGFR mutations were found in the post-afatinib samples of the six responding patients. Further analyses of post-afatinib progressive tumors revealed 28 resistant specific mutations in six genes (HLA-DRB1, AQP7, FAM198A, SEC31A, CNTLN, and ESX1) in three afatinib responding patients. No known EGFR-TKI resistant-associated copy number gains were acquired in the post-afatinib samples. CONCLUSION No differences in survival were observed in patients with EGFR-T790M treated with afatinib compared to those without T790M. Tumors from patients who had progressive disease during afatinib treatment were enriched for mutations in genes involved in Wnt and PI3K-AKT pathways.

Abstract
The seven-membered fused-ring in the title compound, C10H10N2O·H2O, adopts a boat conformation (with the two phenylene C atoms representing the stern and the methylene C atom the prow). In the crystal, two benzodiazepinone molecules are linked about a center of inversion by diazepine–carbonyl N—H⋯O hydrogen bonds. The dimers are further linked by water–diazepine O—H⋯N hydrogen bonds, forming a linear chain.

Abstract
Thanks to the malaria eradication campaign launched in Algeria in 1968, the number of malaria cases fell down significantly from 95,424 cases in 1960 to 30 cases in 1978. At that time the northern part of the country was declared free of Plasmodium falciparum. Only few cases belonging to P. vivax persisted in residual foci in the middle part of the country. In the beginning of the eighties, the south of the country was marked by an increase of imported malaria cases. The resurgence of the disease in the oases coincided with the opening of the Trans-Saharan road and the booming trade with the neighbouring southern countries. Several authors insisted on the risk of introduction of malaria or its exotic potential vectors in Algeria via this new road. Now, the totality of malaria autochthonous cases in Algeria are located in the south of the country where 300 cases were declared during the period (1980-2007). The recent outbreak recorded in 2007 at the borders with Mall and the introduction of Anopheles gambiae into the Algerian territory show the vulnerability of this area to malaria which is probably emphasized by the local environmental changes. The authors assess the evolution of malaria in the Sahara region and draw up the distribution of the anopheles in this area.

Abstract
The donkey placenta is diffuse and epitheliochorial with numerous microplacentomes consisting of a fetal microcotyledonary and a maternal microcaruncular part. The microplacentomal vasculature during the last third of pregnancy has been investigated by light microscopy in comparison to scanning electron microscopy of the materno-fetal contact surface and corrosion casts of blood vessels after plastic instillation from either the microcotyledonary or the microcaruncular side, and, for the first time in a perissodactyle, from both sides. Morphological data were semiquantitatively evaluated. The supplying parts of both, the microcotyledonary and the microcaruncular vascular system are strictly proximo-distally oriented, thus reaching the capillary systems or working parts in the shortest way possible. The straight course of the vasculature, particularly on the fetal side, suggests the occurrence of venulo-arteriolar back diffusion. The fetal capillary system consists of convolutes confronting the maternal septal capillary complexes in a countercurrent way. This materno-fetal blood flow interrelationship is highly efficient in terms of placental exchange, which is further supported (1) by dilations and increasing coiling of the fetal venular capillary limbs in particular and (2) by a decrease in the interhaemal distance from 12.5 to 7.2 microm between the two capillary systems. Besides the countercurrent blood flow interrelationship, some maternal branch arterioles reach the septal capillary system from the maternally oriented pole of the microplacentome or microcaruncle, respectively, resulting in the less efficient crosscurrent blood flow. Hence, in the donkey placenta fetal and maternal blood vessels meet in a mix of countercurrent and crosscurrent flow patterns.

Abstract
UNLABELLED The incidence of metastasis to the thyroid gland in autopsy series varies from 1.25 % to 24%. Metastasis to the thyroid gland is usually considered as a terminal event, and the effectiveness of conventional treatment has been questioned. METHODS Seven patients with metastasis to the thyroid gland were studied retrospectively. Primary tumor origin was identified in all of them. Metastasis to the thyroid gland was confirmed by fine needle aspiration cytology or histology. Data were analyzed for the type of malignant lesions, the clinical course of the disease, and the prognosis after thyroid involvement. RESULTS Two patients had lung as a primary tumor site. Breast, iris, kidney, parotid and soft tissue sarcoma were the involved primary sites in the other cases. The time from the diagnosis of primary tumor to metastasis to the thyroid gland was considerable (ranged from 13- 135 months, median 60 months). Fine needle aspiration cytology detected metastasis in five of seven patients. Treatment was surgery alone or surgery with adjuvant therapy. One patient didn't receive any treatment. CONCLUSIONS In any patient with a previous history of malignancy, no matter how old that history is, a new thyroid mass should be considered as recurrence until proved otherwise. Although detection of metastasis to the thyroid gland often indicates poor prognosis, aggressive surgical and medical therapy may be effective in a small percentage of patients.

Abstract
This study aimed to elucidate development of the areola in the early dromedary placenta in comparison with that of the pig and mare. Placental tissues from 25 pregnant camels were obtained from Cairo abattoir and prepared for light, scanning and transmission electron microscopy by routine methods. Vascular casts were made by injection of 4 : 1 liquid plastic mixture of mercox and methylmethacrylate. Areolar formation was first observed at 4.5 cm curved-crown-rump CVR length, while by 5-9 cm CVR length, the endometrial surface was uneven and studded with numerous uterine gland openings, where corresponding foetal areolae were barely detectable and the foetal areolar cells were of variable appearance and covered with long microvilli. At 10-13 cm CVR length the uterine gland openings developed irregular folds and the maternal areolar cells showed numerous apical blebs. At 14-29 cm CVR length the foetal areolae showed a great increase in height at the expense of their width. At 30-34 cm (CVR) length the maternal areolae appeared discoid and sharply demarcated from the surrounding inter-areolar tissues and the foetal areolae were rounded to irregular in shape with well-developed areolar rims. The vascular casts showed a widely meshed capillary network on the maternal areola, connecting with the pre- and post-capillary vessels, whereas the foetal side showed a relatively dense capillary meshwork. These studies indicate that the areola in the placenta of the one-humped camel is of the regular type like in the pig, and is poorly vascularized.

Abstract
Early discovery of breast cancer in the lactating female will result in improved survival rates. One such marker is the "milk rejection sign," which has rarely been described and consists of the rejection by the nursing infant of the lactating breast that harbors an occult breast carcinoma. Recognition of this particular sign is vital and will enable early diagnosis and improved prognosis.
