Abstract
Background Surrogate biomarkers of efficacy are needed for anti-PD1/PD-L1 therapy, given the existence of delayed responses and pseudo-progressions. We evaluated changes in serum IL-8 levels as a biomarker of response to anti-PD-1 blockade in melanoma and non-small-cell lung cancer (NSCLC) patients. Patients and methods Metastatic melanoma and NSCLC patients treated with nivolumab or pembrolizumab alone or nivolumab plus ipilimumab were studied. Serum was collected at baseline; at 2-4 weeks after the first dose; and at the time-points of response evaluation. Serum IL-8 levels were determined by sandwich ELISA. Changes in serum IL-8 levels were compared with the Wilcoxon test and their strength of association with response was assessed with the Mann-Whitney test. Accuracy of changes in IL-8 levels to predict response was estimated using receiver operation characteristics curves. Results Twenty-nine melanoma patients treated with nivolumab or pembrolizumab were studied. In responding patients, serum IL-8 levels significantly decreased between baseline and best response (P <0.001), and significantly increased upon progression (P = 0.004). In non-responders, IL-8 levels significantly increased between baseline and progression (P = 0.013). Early changes in serum IL-8 levels (2-4 weeks after treatment initiation) were strongly associated with response (P <0.001). These observations were validated in 19 NSCLC patients treated with nivolumab or pembrolizumab (P = 0.001), and in 15 melanoma patients treated with nivolumab plus ipilimumab (P <0.001). Early decreases in serum IL-8 levels were associated with longer overall survival in melanoma (P = 0.001) and NSCLC (P = 0.015) patients. Serum IL-8 levels also correctly reflected true response in three cancer patients presenting pseudoprogression. Conclusions Changes in serum IL-8 levels could be used to monitor and predict clinical benefit from immune checkpoint blockade in melanoma and NSCLC patients.

Abstract
Background Overuse of surveillance imaging in patients after curative treatment for early breast cancer (ebc) was recently identified as one of the Choosing Wisely Canada initiatives to improve the quality of cancer care. We undertook a population-level examination of imaging practices in Ontario as they existed before the launch of that initiative. Methods Patients diagnosed with ebc between 2006 and 2010 in Ontario were identified from the Ontario Cancer Registry. Records were linked deterministically to provincial health care databases to obtain comprehensive follow-up. We identified all advanced imaging exams [aies: computed tomography (ct), bone scan, positron-emission tomography] and basic imaging exams (bies: ultrasonography, chest radiography) occurring within the first 2 years after curative treatment. Poisson regression was used to assess associations between patient or provider characteristics and the rate of aies. Results Of 30,006 women with ebc, 58.6% received at least 1 bie, and 30.6% received at least 1 aie in year 1 after treatment. In year 2, 52.7% received at least 1 bie, and 25.7% received at least 1 aie. The most common aies were chest cts and bone scans. The rate of aies increased with older age, higher disease stage, comorbidity, chemotherapy exposure, and prior staging investigations (p < 0.001). Imaging was ordered mainly by medical oncologists (38%), followed by primary care physicians (23%), surgeons (13%), and emergency room physicians (7%). Conclusions Despite recommendations against its use, imaging is common in ebc survivors. Understanding the factors associated with aie use helps to identify areas for further research and is required to lower imaging rates and to improve survivorship care.

Abstract
PURPOSE To compare the perioperative outcomes of initial, consecutive robotic-assisted transabdominal preperitoneal (R-TAPP) inguinal hernia repair (IHR) cases with consecutive open cases completed by the same surgeons. METHODS Multicenter, retrospective, comparative study of perioperative results from open and robotic IHR using standard univariate and multivariate regression analyses for propensity score matched (1:1) cohorts. RESULTS Seven general surgeons at six institutions contributed 602 consecutive open IHR and 652 consecutive R-TAPP IHR cases. Baseline patient characteristics in the unmatched groups were similar with the exception of previous abdominal surgery and all baseline characteristics were comparable in the matched cohorts. In matched analyses, postoperative complications prior to discharge were comparable. However, from post discharge through 30 days, fewer patients experienced complications in the R-TAPP group than in the open group [4.3% vs 7.7% (p = 0.047)]. The R-TAPP group had no reoperations post discharge through 30 days of follow-up compared with five patients (1.1%) in the open group (p = 0.062), respectively. Multivariate logistic regression analysis which demonstrated patient age > 65 years and the open approach were risk factors for complications within 30 days post discharge in the matched group [age > 65 years: odds ratio (OR) = 3.33 (95% CI 1.89, 5.87; p < 0.0001); open approach: OR = 1.89 (95% CI 1.05, 3.38; p = 0.031)]. CONCLUSIONS In this matched analysis, R-TAPP provides similar postoperative complications prior to discharge and a lower rate of postoperative complications through 30 days compared to open repair. R-TAPP is a promising and reproducible approach, and may facilitate adoption of minimally invasive repairs of inguinal hernias.

Abstract
In a prospective study we evaluated in 48 patients with primary ovarian carcinoma the prognostic value of the preoperative circulating serum levels of CA 125 and TAG-72. Serum levels of CA 125 were above the cutoff level of 35 U/ml in 68% of patients, TAG-72 levels were higher than 6 U/ml in 50% of patients, while the simultaneous use of the two markers increased the sensitivity to 75%. Pretreatment CA 125 and TAG-72 levels were significantly lower (p < 0.05, for both) in patients with well differentiated tumors than in those with moderate or poor differentiation. Similarly, both marker levels were significantly higher (p < 0.001) in patients with residual disease after cytoreductive surgery than in those with no residual tumor. In addition, the CA 125 levels were also higher in initial stages (I-II) than in more advanced stages (III-IV) (p < 0.05), whereas TAG-72 levels were higher (p < 0.05) in patients with mucinous or endometrioid tumors than in those with serous carcinomas. The results further indicated that high preoperative serum levels of CA 125 and TAG-72 were associated with a shorter overall survival (p < 0.001 and p < 0.01, respectively). Finally, separate Cox multivariate analysis showed that preoperative CA 125 and TAG-72 serum levels were, after stage, the strongest factors to predict overall survival (p < 0.0001, p < 0.05 and p < 0.005, respectively) in patients with ovarian carcinoma.

Abstract
The aim of this study was to evaluate the cytosolic tissue-type plasminogen activator (tPA) content in colorectal cancer, its possible relationship with the clinicopathologic parameters of tumors, and its prognostic significance. We have therefore examined by immunoenzymatic assay the cytosolic tPA content in tumors and paired surrounding normal mucosa samples from 162 colorectal cancer patients. Cytosolic tPA levels were significantly higher in surrounding normal mucosa samples than in neoplastic tissues (4.01±5.07 vs 2.63±5.82 ng/mg protein; p<0.0001). By contrast, no significant correlation was found between tPA content and clinicopathologic tumor parameters such as location, Dukes’ stage, histologic grade, and DNA content or S-phase fraction. However, the results indicated that a high cytosolic tPA content (>0.75 ng/mg protein) in tumors predicted for a shorter relapse-free and overall survival (both p<0.05) in 123 resectable colorectal cancer patients who were prospectively evaluated during a mean follow-up period of 32.2 months. This suggests that tPA may give additional information to that provided by other biochemical markers currently used in colorectal cancer.

Abstract
OBJECTIVE/BACKGROUND Guatemala's indigenous Maya population has one of the highest rates of childhood stunting in the world. The goal of this study was to examine the impact of an intensive, individualised approach to complementary feeding education for caregivers on feeding practices and growth over usual care. DESIGN An individually randomised (1:1 allocation ratio), parallel-group superiority trial, with blinding of study staff collecting outcome data. SETTING Rural Maya communities in Guatemala. PARTICIPANTS 324 children aged 6-24 months with a height-for-age Z score of less than or equal to -2.5 SD were randomised, 161 to the intervention and 163 to usual care. INTERVENTIONS Community health workers conducted home visits for 6 months, providing usual care or usual care plus individualised caregiver education. MAIN OUTCOMES MEASURES The main outcome was change in length/height-for-age Z score. Secondary outcomes were changes in complementary feeding indicators. RESULTS Data were analysed for 296 subjects (intervention 145, usual care 151). There was a non-significant trend to improved growth in the intervention arm (length/height-for-age Z score change difference 0.07(95% CI -0.04 to 0.18)). The intervention led to a 22% improvement in minimum dietary diversity (RR 1.22, 95% CI 1.11 to 1.35) and a 23% improvement in minimal acceptable diet (RR 1.23, 95% CI 1.08 to 1.40) over usual care. CONCLUSIONS Complementary feeding outcomes improved in the intervention arm, and a non-significant trend towards improved linear growth was observed. Community health workers in a low-resource rural environment can implement individualised caregiver complementary feeding education with significant improvements in child dietary quality over standard approaches. CLINICAL TRIAL REGISTRATION NUMBER NCT02509936. Stage: Results.

Abstract
OBJECTIVE Stunting is a common cause of early child developmental delay; Guatemala has the fourth highest rate of stunting globally. The goal of this study was to examine the impact of an intensive community health worker-led complementary feeding intervention on early child development in Guatemala. We hypothesised that the intervention would improve child development over usual care. DESIGN A substudy from a larger individually randomised (1:1 allocation ratio), parallel-group superiority trial, with blinding of study staff collecting outcomes data. SETTING Rural, indigenous Maya communities in Guatemala. PARTICIPANTS 210 stunted children (height-for-age z-score ≤-2.5) aged 6-24 months, previously randomised to usual care (106) or an intensive complementary feeding intervention (104). 84 in the intervention and 91 in the usual care arm agreed to participate. INTERVENTIONS Community health workers conducted monthly home visits for 6 months, providing usual care or individualised complementary feeding education. MAIN OUTCOME MEASURES The primary outcomes were change in z-scores for the subscales of the Bayley Scales of Infant Development (BSID), Third Edition. RESULTS 100 individuals were included in the final analysis, 47 in the intervention and 53 in the usual care arm. No statistically significant differences in age-adjusted scores between the arms were observed for any subscale. However, improvements within-subjects in both arms were observed (median duration between measurements 189 days (IQR 182-189)). Mean change for subscales was 0.45 (95% CI 0.23 to 0.67) z-scores in the intervention, and 0.43 (95% CI 0.25 to 0.61) in the usual care arm. CONCLUSIONS An intensive complementary feeding intervention did not significantly improve developmental outcomes more than usual care in stunted, indigenous Guatemalan children. However, both interventions had significant positive impacts on developmental outcomes. TRIAL REGISTRATION NUMBER NCT02509936. STAGE Results.

Abstract
The influence of the position of the aliphatic chain at the glycerol backbone has been basically unknown. Solely the results of 2-monopalmitoyl-rac-glycerol obtained at ≥13 °C indicated an essential influence of the position of the palmitoyl group at the glycerol backbone, substantiated by a disordered packing of the alkyl chains. Therefore, the present study extends the comprehensive characterization of 2-monopalmitoyl-rac-glycerol monolayers to the low-temperature range for highlighting the effect of the position of the aliphatic chain at the glycerol backbone of monoalkanoylglycerolester monolayers. Systematic studies of the thermodynamic behavior, the morphological features, and the 2D lattice structures of 2-monopalmitoyl-rac-glycerol monolayers at ≤10 °C allow useful conclusions. Large differences between the π-A isotherms of 1- and 2-monopalmitoyl-rac-glycerol monolayers and their thermodynamic analysis indicate that the change of the substitution from position 1 to position 2 of glycerol backbone is consistent with a shortening of the alkyl chain by roughly two CH2 groups. Quantum chemical calculations of the molecular structure and packing calculations are in reasonable agreement with the thermodynamic results. Considerable diversity in the mesoscopic domain topography exists between the monoalkanoylglycerol esters with the aliphatic chain positioned at the end of the glycerol backbone (1-position) and those with the aliphatic chain in the middle of the glycerol backbone (2-position). The new faceted shape of the 2-monopalmitoyl-rac-glycerol domains, before they develop branched fractal-like structures at the edges, is the essential difference to the round or cardioid-like 1-monoalkanoylglycerol domains. In the low-temperature range, well-defined orthorhombic lattice structures exist at all surface pressures. Comparing all GIXD data from the three racemic compounds (1-monostearoyl-rac-glycerol, 1-monopalmitoyl-rac-glycerol, and 2-monopalmitoyl-rac-glycerol) shows that 2-monopalmitoyl-rac-glycerol behaves as 1-monomyristoyl-rac-glycerol, i.e., the shift from position 1 to position 2 of the glycerol backbone is equivalent to a shortening of the alkyl chain.

Abstract
In the period from July 2008 to 2010, a disease episode resulting in serious economic losses in the major production area of the Chilean poultry industry was reported. These losses were associated with respiratory problems, increase of condemnations, drops in egg production and nephritis in breeders, laying hens and broilers due to infections with infectious bronchitis virus (IBV). Twenty-five IBV isolates were genotyped and four strains were selected for further testing by pathotyping and protectotyping. Twenty-four IBV isolates were of the Q1 genotype. The experiments also included comparing the ability of six vaccination programmes to induce virus neutralizing antibodies (VNA) in layers against four selected Chilean strains. Despite the high genetic homology in the S1 gene between the four strains, the heterogeneity in biological behaviour of these different Q1 strains was substantial. These differences were seen in embryonated eggs, in cell culture, in pathogenicity and in level of cross-protection by IBV Massachusetts (Mass) vaccination. This variability underlines the importance of testing more than one strain per serotype or genotype to determine the characteristics of a certain serotype of genotype. The combination of Mass and 793B vaccine provided a high level of protection to the respiratory tract and the kidney for each strain tested in the young birds. The combination of broad live priming using Mass and 793B vaccines and boosting with multiple inactivated IBV antigens induced the highest level of VNA against Q1 strains, which might be indicative for higher levels of protection against Q1 challenge in laying birds.

Abstract
OBJECTIVE The aim of the study was to evaluate whether the neuropsychiatric symptoms interfere with cognitive impairment detection in primary care and to describe which of them generate more confusion. DESIGN Descriptive and observational study. LOCATION Mobile psychiatric unit in collaboration with primary healthcare centers in Barcelona. PARTICIPANTS A total of 104 patients over 65years referred to mobile psychiatric unit from primary healthcare clinicians suspecting mental disease. MAIN MEASUREMENTS All patients received a DSM-IV-TR diagnosis. We included in the study the Mini Mental State Examination (MMSE), Neuropsichiatric Inventory, Severe Psychiatric Illness scale, Global Assessment of Functioning, Clinical Global Impression and Word Health Organisation Dissability Assessment Schedule. RESULTS 55.8% of patients referred from primary care had altered MMSE score. Neuropsychiatric symptoms more frequently associated with suspected cognitive impairment were delusions, hallucinations, agitation, disinhibition, irritability and purposeless motor behavior. CONCLUSIONS When psychiatric symptoms of Severe Mental Disorder (SMD) are detected in elderly individuals with no history of SMD, cognitive impairment should be suspected and a screening test be done.

Abstract
On the basis of tissue-specific enzyme activity and inhibition by catalytic products, Hans Krebs first demonstrated the existence of multiple glutaminases in mammals. Currently, two human genes are known to encode at least four glutaminase isoforms. However, the phylogeny of these medically relevant enzymes remains unclear, prompting us to investigate their origin and evolution. Using prokaryotic and eukaryotic glutaminase sequences, we built a phylogenetic tree whose topology suggested that the multidomain architecture was inherited from bacterial ancestors, probably simultaneously with the hosting of the proto-mitochondrion endosymbiont. We propose an evolutionary model wherein the appearance of the most active enzyme isoform, glutaminase C (GAC), which is expressed in many cancers, was a late retrotransposition event that occurred in fishes from the Chondrichthyes class. The ankyrin (ANK) repeats in the glutaminases were acquired early in their evolution. To obtain information on ANK folding, we solved two high-resolution structures of the ANK repeat-containing C termini of both kidney-type glutaminase (KGA) and GLS2 isoforms (glutaminase B and liver-type glutaminase). We found that the glutaminase ANK repeats form unique intramolecular contacts through two highly conserved motifs; curiously, this arrangement occludes a region usually involved in ANK-mediated protein-protein interactions. We also solved the crystal structure of full-length KGA and present a small-angle X-ray scattering model for full-length GLS2. These structures explain these proteins' compromised ability to assemble into catalytically active supra-tetrameric filaments, as previously shown for GAC. Collectively, these results provide information about glutaminases that may aid in the design of isoform-specific glutaminase inhibitors.

Abstract
IntroductionAlthough physical restraint (PR) is a non-rarely practice on psychiatry there are few studies that focus the attention on the risk factors for this intervention. PR is a legitimacy practice when is needed and well applied but is not free from side effects. Knowing risk factors might be useful to improve the application of PR.ObjectivesStudy the risk factors involved with the use of PR at patient's home in individuals with schizophrenia before the involuntary transport (IT) to a psychiatric facility.MethodsIs a descriptive and observational study of 267 psychotic patients that were assisted by a psychiatric home care unit (EMSE) in Barcelona during their IT. The sample was divided in two groups, depending on the need of PR. Socio-demographic data were collected as well as positive and negative syndrome scale (PANSS), WHO disability assessment schedule (WHO/DAS), global assessment of functioning scale (GAF), Scale to assess unawareness of mental disorder (SUMD). Aggressiveness was assessed by PANSS-EC consisting of 5 items: excitement, tension, hostility, uncooperativeness and poor impulse.ResultsFrom the 267 psychotic patients 109 required PR. 154 were male and the average of age was 47. The results were significant in the PR group versus no PR for PANSS-EC (P = 0.000), as well as WHO/DAS (P = 0.017), GAF (P = 0.042), Positive PANSS (P = 0.000), age (P = 0.001) and substance use (P = 0.012). Were no significant for gender, insight or Negative PANSS.ConclusionsAggressiveness and violence were the most important PR related factors followed by positive symptoms, age, substance use and global functioning.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
New biological models are incorporating the realistic processes underlying biological responses to climate change and other human-caused disturbances. However, these more realistic models require detailed information, which is lacking for most species on Earth. Current monitoring efforts mainly document changes in biodiversity, rather than collecting the mechanistic data needed to predict future changes. We describe and prioritize the biological information needed to inform more realistic projections of species' responses to climate change. We also highlight how trait-based approaches and adaptive modeling can leverage sparse data to make broader predictions. We outline a global effort to collect the data necessary to better understand, anticipate, and reduce the damaging effects of climate change on biodiversity.

Abstract
Inequalities between men and women are common and well-documented. Objective indexes show that men are better positioned than women in societal hierarchies-there is no single country in the world without a gender gap. In contrast, researchers have found that the women-are-wonderful effect-that women are evaluated more positively than men overall-is also common. Cross-cultural studies on gender equality reveal that the more gender egalitarian the society is, the less prevalent explicit gender stereotypes are. Yet, because self-reported gender stereotypes may differ from implicit attitudes towards each gender, we reanalysed data collected across 44 cultures, and (a) confirmed that societal gender egalitarianism reduces the women-are-wonderful effect when it is measured more implicitly (i.e. rating the personality of men and women presented in images) and (b) documented that the social perception of men benefits more from gender egalitarianism than that of women.
