From Mixed Hyperplastic/Adenomatous Polyp to Sessile Serrated Lesion: A Long and Winding Road for Long and Winding Crypts
Authors: Booth Adam L. , Taggart Melissa W. , Ono Yuho , Gonzalez Raul S. 
Published: December 2020

Context.—
During the past 3 decades, numerous articles in the literature have offered terminology, diagnostic criteria, and consensus recommendations regarding the entity currently referred to by the World Health Organization as sessile serrated lesion. Given the many names and various, variably reproducible diagnostic criteria ascribed to sessile serrated lesion, confusion persists for many pathologists and gastroenterologists regarding the diagnosis. This distinction is important, as sessile serrated lesion can progress to malignancy, unlike its main differential diagnosis, hyperplastic polyp. Research studies have shed light on the characteristic architecture and morphology, immunohistochemical patterns, and molecular alterations of sessile serrated lesion, and multiple consensus meetings around the globe have developed their criteria and nomenclature, often clashing or mixing terms.

Objective.—
To provide a narrative review from the entity's early description to our current understanding.

Data Sources.—
The existing scientific and clinical literature, published texts, medical society recommendations, and specialty consensus guidelines.

Conclusions.—
The current World Health Organization criteria are a distillation of this scientific process, but terminology is still a point of contention worldwide.

Published: December 2020

A variety of predictors are available for ovarian stimulation cycles in assisted reproductive technology (ART) forecasting ovarian response and reproductive outcome in women including biomarkers such as anti- Müllerian hormone (AMH). The aim of our present study was to compare the relationship between AMH levels and pregnancy outcomes in patients undergoing intra-cytoplasmic sperm injection (ICSI). Overall, fifty patients (n = 50), aged 20–45 years were recruited for the present prospective study. Three AMH levels were presented with high often poly cystic ovarian syndrome (PCOS) amongst 52.4% patients, 40.5% in normal and 7.1% in low to normal, correspondingly. There was statistically significant relationship between AMH and day of embryo transfer (p < 0.05). The Pearson analysis between AMH, age, E2 and FSH displayed no statistically significant relationship between E2 and AMH (p < 0.05) and negative correlation between FSH and age (p > 0.05). The area under the receiver operating characteristic curve for E2 was 0.725 and for AMH levels as predictors of CPR was 0.497 indicating E2 as better predictor than AMH. The number of oocytes, mature oocytes and fertilized oocytes all presented a weak positive relationship to AMH. Our results confirm the clinical significance of AMH to accurately predict ovarian reserve as a marker and its limitations to use as predictor for a positive pregnancy outcome. Additional prospective studies should be conducted to validate the predictive capability of AMH levels for the outcome of clinical pregnancy.

Aims: The study focused on assessment of the knowledge level of fish farmers on scientific operation of composite fish culture. It specifically examined the profile, socio–economic, psychological, situational characteristics and knowledge level on scientific composite fish farming.
Study Design: Ex-post facto research design was followed.
Place and Duration of the Study: Krishi Vigyan Kendra, Rudrur, Nizamabad district, Telangana, India, 2019-20.
Methodology: To assess the knowledge level of fish farmers on composite fish culture in Nizamabad district, 50 fish farmers from fishing communities with prevalence fish farming and artisanal fisheries were randomly selected and interviewed with a pre-test interview schedule. All the farmers were imparted three days specialized training programme on composite fish culture and re-assessed their knowledge after its completion.
Results: The study revealed that majority of the respondents were middle aged (48.00%), lliterates (72.00%), with medium fish farming experience (58.00%)and majority had low level of scientific orientation towards composite fish culture (32.00%). Before training only 18.00 per cent fish farmers belonged to high level of knowledge category while 58.00 per cent (P<0.01) of fish farmers possessed high level of knowledge after training.
Conclusion: It may be concluded from the present study that knowledge level on scientific fish culture is low regarding composite fish culture and training is an effective tool to improve the knowledge and understanding of fish farmers.

Published: July 2002

AbstractObjective: We sought to estimate the proportion of women immunized against tetanus while attending prenatal care in the developing countries. Method: We computed the ratio of the percentage of births to women immunized against tetanus to the percentage of births to women with prenatal care (TP ratio). A TP ratio is lower than 100% if not every woman attending prenatal care is immunized. We used 1986–1992 Demographic and Health Surveys data from 38 countries. Results: The mean TP ratios were 86% in Africa (n = 23), 79% in Asia (n = 6) and 60% in Latin America and the Caribbean (n = 9). The TP ratio was lower than 75% in 15 countries. Of these, four had a TP ratio lower than 50%. Conclusion: In many countries the number of pregnant women immunized against tetanus is lower than the number of women attending prenatal care, suggesting that prenatal services are missing opportunities to immunize attending women.
Designing dementia treatment studies: Diagnosis, efficacy criteria, and duration
Authors: Spiegel R , Irwin P 
Published: July 2002

SummaryDevelopment of treatments for dementia is beset by special problems in defining the diagnosis, establishing efficacy criteria, and specifying the necessary duration of study. There is need for agreement among clinicians and scientists on diagnostic subgroups of dementia. Similarly, there is a need for harmonization of the regulatory guidelines in Europe, Japan, and the United States regarding the decision set of variables on which to base efficacy claims. The duration of trials must be based upon the intended claim: transient symptomatic benefit, maintained symptomatic benefit, or a therapeutic effect on disease progression. Claims other than transient benefit require long-term trials, suggested to be of at least six months in duration. Problems with long-term studies include slow patient accrual, high dropout rates, changing milieu, low return on investment, and lack of unanimity regarding regulatory requirements. Regulatory authorities must come to some accord, consonant with current clinical/scientific wisdom and consensus, regarding diagnosis, efficacy criteria, and feasible study duration, in order to attract continued sponsor investment in the development of antidementia treatments.
Announcing the winner of the IJGO Prize Paper Award for 2000 Award article

Published: July 2002

AbstractObjective: To investigate the variations of nucleated red blood cell (NRBC) counts in acute and chronic fetal hypoxia and to examine if it could be possible to establish a cutoff value for the number of NRBCs for prediction of fetal acidosis. Method: We prospectively studied 77 pregnant women. Patients were grouped as acute (n=11) and chronic fetal distress (n=21) and controls (n=45). At delivery the umbilical cord was double clamped and blood samples were collected. Results: The mean NRBC counts in chronic fetal distress group was higher than acute fetal distress. NRBC counts were found to be correlated with umbilical cord pH (r=−0.57; P<0.001). The cutoff value predicting fetal acidosis was determined as 14/100 leukocytes (sensitivity 87%, specificity 81%) by using ROC analysis. Conclusion: The duration and the severity of fetal asphyxia may be predicted by the number of NRBCs per leukocyte.
Thrombocytopenia, hypertension and seizures in eclampsia
Authors: Gracia P. Vigil‐De , García‐Cáceres E. 
Published: July 2002

AbstractObjective: Mortality by eclampsia most likely relies on factors that are associated with seizures, but not directly related to them. The objective of the current study is to analyze these probable factors. Method: This study evaluates patients with eclampsia only. Age, parity, weeks of gestation, blood pressure, platelet counts and cause of death were analysed. The groups of survivors and fatalities were compared using relative risk (RR) with 95% confidence intervals (CI), χ2 and Student's t‐test. Results: A total of 446 cases of eclampsia were studied, of which there were 371 survivors and 75 deaths. The incidence was 14.2/10000 births with mortality of 14.4%. Mortality was more frequent in patients over 25 years of age (P < 0.005). The diastolic blood pressure showed significant difference between the survivor and fatality group (P < 0.05). Before convulsion, thrombocytopenia was present in 148 patients (33.2%) of which 95 survived and 53 died (RR = 2.76; 95% CI 2.20–3.46; P < 0.0000001). Conclusions: Mortality by eclampsia is directly related to age, diastolic blood pressure ≥110 mmHg, seizure and thrombocytopenia. Our findings suggest poor maternal prognosis if seizures occur associated with thrombocytopenia.
Multidentate, V‐Shaped Pyridine Building Blocks as Tectons for Crystal Engineering

Published: December 2020

AbstractThe formation of supramolecular structural units through self‐assembly is a powerful method to design new architectures and materials endowed with specific properties. With the aim of adding a group of versatile tectons to the toolkit of crystal engineers, we have devised and synthesised four new V‐shaped building blocks characterised by an aryl acetylene scaffold comprising three substituted pyridine rings connected by two triple bonds. The judicious choice of different substituents on the pyridine rings provides these tectons with distinctive steric, electrostatic and self‐assembly properties, which influence their crystal structures and their ability to form co‐crystals. Co‐crystals of the tectons with tetraiododifluorobenzene were obtained both via traditional and mechanochemical crystallisation strategies, proving their potential use in crystal engineering. The energetic contributions of the supramolecular interactions at play in the crystal lattice have also been evaluated to better understand their nature and strength and to rationalise their role in designing molecular crystals.
Concentration‐Dependent Self‐Assembly of an Unusually Large Hexameric Hydrogen‐Bonded Molecular Cage

Published: December 2020

AbstractThe sizes of available self‐assembled hydrogen‐bond‐based supramolecular capsules and cages are rather limited. The largest systems have volumes of approximately 1400–2300 Å3. Herein, we report a large, hexameric cage based on intermolecular amide–amide dimerization. The unusual structure with openings, reminiscent of covalently linked cages, is held together by 24 hydrogen bonds. With a diameter of 2.3 nm and a cavity volume of ∼2800 Å3, the assembly is larger than any previously known capsule/cage structure relying exclusively on hydrogen bonds. The self‐assembly process in chlorinated, organic solvents was found to be strongly concentration dependent, with the monomeric form prevailing at low concentrations. Additionally, the formation of host–guest complexes with fullerenes (C60and C70) was observed.
Mediated Generation of Conjugate Acid by UV and Blue Sensitizers with Upconversion Nanoparticles at 980 nm
Authors: Oprych Dennis , Strehmel Bernd 
Published: December 2020

AbstractNIR and UV exposure of systems comprising upconversion nanoparticles (UCNP) based on NaYF4:Tm/Yb@NaYF4, a sensitizer absorbing either in the blue or UV region, and an onium salt with weak coordinating anion resulted in formation of conjugate acid (con‐H+). That was namely Ivocerin (di(4‐methoxybenzoyl)diethylgermane), ITX (2‐iso‐propyl thioxanthone), anthracene, pyrene, rubrene, camphore quinone, and a strong fluorescent coumarin (1,1,6,6,8‐pentamethyl‐2,3,5,6‐tetrahyhdro‐1H,4H‐11‐oxa‐3a‐aza‐benzo[de]anthracene‐10‐one). Quantification occurred by treatment with Rhodamine B lactone whose color switched to intensive red after photolytic formation of con‐H+. Exposure with a NIR laser at 980 nm resulted in less con‐H+ compared to 395 nm where all sensitizers absorb radiation. UCNP did not mainly interfered formation of con‐H+. The different rates obtained in both experiments responsibly explain the failure and success to initiate polymerization of epoxides applying ether 980 nm or 395 nm excitation, respectively.

Published: December 2020

AbstractA new mode of aromatic metamorphosis has been developed, which allows thiophenes and their benzo‐fused derivatives to be converted to a variety of exotic heteroles. This transformation involves 1) the efficient generation of key 1,4‐dianions by means of desulfurative dilithiation with lithium powder and 2) the subsequent trapping of the dianions with heteroatom electrophiles in a one‐pot manner. Via the desulfurative dilithiation, the sulfur atoms of thiophenes are replaced also with a carbon–carbon double bond or a 1,2‐phenylene for the construction of benzene rings.
Big data and machine learning framework for clouds and its usage for text classification
Authors: Pintye István , Kail Eszter , Kacsuk Péter , Lovas Róbert 
Published: December 2020

AbstractReference architectures for big data and machine learning include not only interconnected building blocks but important considerations (among others) for scalability, manageability and usability issues as well. Leveraging on such reference architectures, the automated deployment of distributed toolsets and frameworks on various clouds is still challenging due to the diversity of technologies and protocols. The paper focuses particularly on the widespread Apache Spark cluster with Jupyter as the particularly addressed framework, and the Occopus cloud‐agnostic orchestrator tool for automating its deployment and maintenance stages. The presented approach has been demonstrated and validated with a new, promising text classification application on the Hungarian academic research infrastructure, the OpenStack‐based MTA Cloud. The paper explains the concept, the applied components, and illustrates their usage with real use‐case measurements.

AbstractIn multihost disease systems, differences in mortality between species may reflect variation in host physiology, morphology, and behavior. In systems where the pathogen can persist in the environment, microclimate conditions, and the adaptation of the host to these conditions, may also impact mortality. White‐nose syndrome (WNS) is an emerging disease of hibernating bats caused by an environmentally persistent fungus, Pseudogymnoascus destructans. We assessed the effects of body mass, torpid metabolic rate, evaporative water loss, and hibernaculum temperature and water vapor deficit on predicted overwinter survival of bats infected by P. destructans. We used a hibernation energetics model in an individual‐based model framework to predict the probability of survival of nine bat species at eight sampling sites across North America. The model predicts time until fat exhaustion as a function of species‐specific host characteristics, hibernaculum microclimate, and fungal growth. We fit a linear model to determine relationships with each variable and predicted survival and semipartial correlation coefficients to determine the major drivers in variation in bat survival. We found host body mass and hibernaculum water vapor deficit explained over half of the variation in survival with WNS across species. As previous work on the interplay between host and pathogen physiology and the environment has focused on species with narrow microclimate preferences, our view on this relationship is limited. Our results highlight some key predictors of interspecific survival among western bat species and provide a framework to assess impacts of WNS as the fungus continues to spread into western North America.
A context analysis of bobbing and fin‐flicking in a small marine benthic fish
Authors: Santon Matteo , Deiss Felix , Bitton Pierre‐Paul , Michiels Nico K. 
Published: December 2020

AbstractMost antipredator strategies increase survival of individuals by signaling to predators, by reducing the chances of being recognized as prey, or by bewildering a predator's perception. In fish, bobbing and fin‐flicking are commonly considered as pursuit‐deterrent behaviors that signal a predator that it has been detected and thus lost its surprise‐attack advantage. Yet, very few studies assessed whether such behavioral traits are restricted to the visual presence of a predator. In this study, we used the yellow black‐headed triplefin Tripterygion delaisi to investigate the association between these behaviors and the visual exposure to (a) a black scorpionfish predator (Scorpaena porcus), (b) a stone of a size similar to that of S. porcus, (c) a conspecific, and (d) a harmless heterospecific combtooth blenny (Parablennius sanguinolentus). We used a laboratory‐controlled experiment with freshly caught fish designed to test for differences in visual cues only. Distance kept by the focal fish to each stimulus and frequency of bobbing and fin‐flicking were recorded. Triplefins kept greater distance from the stimulus compartment when a scorpionfish predator was visible. Bobbing was more frequent in the visual presence of a scorpionfish, but also shown toward the other stimuli. However, fin flicks were equally abundant across all stimuli. Both behaviors decreased in frequency over time suggesting that triplefin become gradually comfortable in a nonchanging new environment. We discuss why bobbing and fin‐flicking are not exclusive pursuit‐deterrent behaviors in this species, and propose additional nonexclusive functions such as enhancing depth perception by parallax motion (bobbing) or signaling vigilance (fin‐flicking).
