Authors: PRZHIBORO ANDREY A. , PARAMONOV NIKOLAY M. , BAZOVA NATALIA V.
Published: November 2019

The distribution of Hexatoma (Eriocera) ussuriensis Alexander is analyzed on the basis of the authors' original material and the specimens kept in the collection of the Zoological Institute, St. Petersburg (including the types). Diagnostic characters of H. ussuriensis are summarized. H. ussuriensis is recorded for the first time from Mongolia, Japan and eastern Siberia (including new records from five provinces of Russia: Kemerovo Province, Republic of Altai, Krasnoyarsk Territory, Irkutsk Province, and Buryatia). The known distribution of this species is wide; it ranges from ca. 61° to 43°N, from 30 to 650 m above the sea level, and covers different landscape-climatic zones (from boreal forest to dry steppe). Records of H. ussuriensis are confined mostly or entirely to different-type running waters, which probably serve as larval habitats. They are briefly characterized and illustrated. Adults of H. ussuriensis were for the first time reared from larvae collected in the Chikoi River (Buryatia, Russia).

Thoracic spiracular gill structure of Lipsothrix (Diptera, Limoniidae) in Britain described from scanning electron micrographs

Authors: Hancock GEOFFREY E. , Hewitt STEPHEN M. , Godfrey ANDREW , Mullin MARGARET
Published: November 2019

Recent ecological surveys have resulted in rearing examples of the five British members of the genus Lipsothrix (Diptera, Limoniidae). These have provided samples for investigating the morphology of their thoracic spiracular gill by the use of scanning electron microscopy. This reveals unique characteristics for the five species available. The differing structures may relate to varying larval habitats. A species identification key for pupae is based on features of the plastron. Information from the juvenile stages supports the placing of Lipsothrix in the Limoniinae.

Checklist of the caddisflies of the Iberian Peninsula and Balearic Islands (Trichoptera)
Authors: GONZÁLEZ MARCOS A. , MARTÍNEZ JESÚS
Published: November 2019

The first faunistic review of the caddisflies (Trichoptera) from the Iberian Peninsula, using as a reference the Limnofauna Europaea, was presented in 1987 and included 267 species. A comprehensive faunistic, nomenclatorial and systematically revised checklist of the Iberian caddsiflies was given in 1992 and included 294 species for the Iberian Peninsula and Balearic Islands.      Since 1992 our knowledge of the faunistic composition of some peninsular areas, especially of the meridional half and the Mediterranean region have considerably improved. It is now possible to update significantly the knowledge of caddisflies in the Iberian Peninsula and Balearic Islands. We critically reviewed the literature data and supplemented these with our recent new records. We also take into consideration some unpublished collections of the authors from different Iberian regions.      The checklist now contains 342 species (327, 185, 60 and 18 species from the Spanish mainland, the Portuguese mainland, Andorra, and the Balearic Islands, respectively), belonging to 75 genera and 22 families. Together, 4 families, i.e., Limnephilidae (23.7%), Hydroptilidae (14.9%), Leptoceridae (10.5%) and Rhyacophilidae (9.3 %), comprise 57% of the Iberian fauna.
Structure and morphological types of the antennal olfactory sensilla in Phryganeidae and Limnephilidae (Insecta: Trichoptera)

Authors: IVANOV VLADIMIR D. , MELNITSKY STANISLAV I.
Published: November 2019

Structure of the antennal segments and ultrastructure of the sensilla in representatives of Phryganeidae and Limnephilidae have been investigated using scanning electronic microscopy (SEM) and optical microscopy. Twelve types of antennal sensilla have been observed and their preliminary classification based on cuticular structures is discussed. All types of sensilla are unevenly distributed on the surface of the antennal flagellum. The most characteristic feature is the presence of specialized sensory fields on the antennal segments (flagellomeres). These are the depressed ventral areas in the apical parts of flagellomeres in all Phryganeidae and Dicosmoecinae (Limnephilidae) and the elongate ventrolateral areas in more advanced Limnephilidae from the subfamilies Stenophylacinae and Limnephilinae. In contrast to the lower Dicosmoecinae with a wide variety of pseudoplacoid sensilla, the antennal surfaces of both sexes in the subfamilies Limnephilinae and Stenophylacinae have only specialized, dentate, small pseudoplacoids. These data suggest internal heterogeneity in the family Limnephilidae, where Dicosmoecinae have very different antennal structures, and support an hypothesis of separate status for Dicosmoecinae. The families Phryganeidae, Plectrotarsidae and Goeridae have only the forked sensilla while Apataniidae and Brachycentridae only mushroom-like pseudoplacoids. Comparison to representatives of Rhyacophilidae, Molannidae, Hydropsychidae, and Leptoceridae indicates that there are significant variations in the sensory structures of Trichoptera antennae. Functional aspects of the antennal structures in relation to the behavior interaction with the air currents are discussed.

Important life history traits of Chaetopteryx villosa (Fabricius, 1798) (Trichoptera, Limnephilidae)

Authors: MAJECKA KATARZYNA , MAJECKI JANUSZ , WALASZEK ANNA
Published: November 2019

Long-term studies of the life cycle of Chaetopteryx villosa (Fabricius) have been conducted in Wolbórka Spring, in the vicinity of Łódź (Central Poland). The emergence period of adults lasts from the beginning of October until mid December. During this relatively long period, adults are exposed to diverse weather conditions. Low (sometimes below zero) ambient temperatures influence the survival of adults. Although oviposition usually starts at the end of October, freshly laid eggs were found even in January. These temperatures also determine the activity of predators as well as the development and survival of eggs laid on land. Some egg masses have been transferred to the laboratory and bred at different temperatures.
Photography of Trichoptera in flight
Authors: McIlleron W. Geoff , De Moor Ferdinand C.
Published: November 2019

Whereas photography of insects at rest is used for a wide variety of purposes, including illustrating publications and aiding their identification, photography of insects in flight is more challenging and little practiced. This paper describes a system that uses a digital single-lens-reflex camera combined with commercial-level flashes (with electronic power settings to give very short exposures) and simple electronics in a rig that can be used to capture high quality images of night-flying insects. With such a rig, hundreds of images of free flying Trichoptera have been obtained. Preliminary observations of night-flying Athripsodes bergensis (Leptoceridae) indicate that this system could be used for studying the mechanics of flight, wing beat frequency, aerodynamics, flying speed, aerial activity, and behavioural ecology of night-flying insects in their natural environment.      This paper briefly describes the technique as applied at a site on the banks of the Groot River in the southern Cape region of South Africa between October 2008 and April 2009 and presents a selection of the images obtained.
Spatio-temporal variations of caddisfly assemblages in a chalk stream, Balaton Upland, Hungary
Authors: SZIVÁK ILDIKÓ , MÓRA ARNOLD , TÖRÖK JÚLIA KATALIN
Published: November 2019

In 2006–2007 larval caddisfly assemblages of a semi-natural calcareous stream (Örvényesi Creek) were studied. Characteristic sections can be detected along the whole length of the stream, which passes through diverse types of vegetation, resulting in highly heterogeneous aquatic habitats. Based on an annual survey of different aquatic habitats, our aims were to give an overview of the spatio-temporal distribution of the larval caddisfly assemblages in the Örvényesi Creek and to find indicator species characterizing different sections of the stream. In order to show the spatio-temporal patterns, samples were collected at 7 locations with different streambed morphology, from spring to the mouth of the stream. Caddisfly larvae were collected in every 3rd week during a 1 year period using the “kick and sweep” method. Multivariate analyses were carried out to explore the spatio-temporal structure of caddisfly assemblages. The indicator value method was applied to detect indicator species for different sections of the stream. A rich caddisfly fauna (20 taxa) was found in the Örvényesi Creek. Fast-running and relatively cold-water hypocrenal sections were characterized by Beraea maurus and Apatania muliebris at high indicator value. Three Limnephilidae species (Limnephilus rhombicus, Limnephilus lunatus and Glyphotaelius pellucidus) were identified as significant indicator species for slow flowing, lentic habitats. Along the length of the stream, distinctive spatial and temporal changes were detected in the distribution of the caddisfly assemblages. These changes were mainly connected to variations in morphology of the streambed, phenology of individual taxa, extreme weather conditions and human impacts.

Predatory mite fauna associated with agri-horticultural crops and weeds from the Gangetic Plains ofWest Begal, India*

Authors: KARMAKAR KRISHNA , GUPTA SALIL K.
Published: November 2019

Astudy was conducted in 2008–2009 to explore the predatory mite fauna from different agri-horticultural crops and weeds in the Gangetic plains ofWest Bengal. A total of 31 species belonging to nine genera, seven families and two orders were identified; they are listed along with their prey, period of occurrence and the plant habitats in which they were recorded. The most frequently collected specieswere the phytoseiids Amblyseius largoensis (Muma) and Neoseiulus longispinosus (Evans), the stigmaeids Agistemus spp. and the anystidWalzia indiana Smith-Meyer&Ueckermann.Given the frequencywithwhich these mites were found, they can be considered potentially useful in suppressing the associated prey mites. The phytoseiids Paraphytoseius multidentatus Swirski & Schechter, Euseius ovalis (Evans), Euseius coccineae (Gupta), Neoseiulus fallacis (Garman) and the cheyletid Cheletogenes ornatus (Canestrini&Fanzago) were less frequently found and less abundant, implying that their impact on prey population is less important. The remaining species were rare.
Mine-damaged leaves by Phyllocnistis citrella Stainton provide refuge for phytoseiids on grapefruit in Florida and Texas*

Authors: VILLANUEVA RAUL T. , CHILDERS CARL C.
Published: November 2019

Damages caused by pests to leaves can indirectly affect populations of other associated arthropods. The relative abundance of mites was compared across young healthy leaves, mature healthy leaves and mature leaves damaged by the citrus leafminer, Phyllocnistis citrella Stainton, on grapefruit in Florida and Texas. The spider mite Eotetranychus sexmaculatus (Riley) (Tetranychidae) was significantly more abundant on mined leaves in Florida, whereas in Texas tetranychids were found sporadically. Predaceous phytoseiid mites (Phytoseiidae) were significantly more abundant on mature mined leaves than on mature leaves without mines. Iphiseiodes quadripilis (Banks) (n= 139), Typhlodromalus peregrinus (Muma) (n= 122) and Euseius mesembrinus (Dean) (n= 18) were the most abundant phytoseiids in Florida; E. mesembrinus was the dominant species in Texas [>90% of identified specimens (n=13)]. Although relatively high numbers of predaceous stigmaeid mites (Stigmaeidae) were found in some occasions in Florida, they had a patchy distribution, resulting in no significant differences between mined and unmined leaf types in most sampling dates. They were not found in Texas.

Authors: LIMA MAYRARAMOS , RODRÍGUEZ HÉCTOR , GONZÁLEZ ADAI , GONZÁLEZ MARIANELA
Published: November 2019

The Red PalmMite (RPM), Raoiella indica Hirst, has been reported to attack several plant species in theAmericas, mainly palm and banana species. High population levels of this mite have been found damaging coconut and banana in Cuba. The objectives of this work were to estimate the potential of R. indica as a pest in Cuba and to evaluate the effectiveness of Dicofol and Bacillus thuringiensis for its control. The following activities were conducted to meet the first objective: a) evaluation of its host range; b) comparison of its biotic potential on coconut and banana leaves; and c) determination of its population dynamics on banana (Musa acuminata Colla Cavendish subgroup). To meet the second objective, a study was conducted to determine the effect of the chemical acaricideDicofol and line 13 of Bacillus thuringiensis (LBt-13) in the control of RPM. Twenty one plant species were found as host, of which 11 areArecaceae, threeMusaceae, two Heliconiaceae, two Zingiberaceae, one Strelitziaceae and two Cycadaceae.Mycrocycas calocoma (Miq.)A.D.C and Cycas sp. are reported as new hosts for this mite. The immature phase was completed in about the same time on coconut and banana leaves, respectively 31.4 ± 3.3 and 33.4 ± 4.8 days, 26.3 ± 1.3°C, 75 ± 4%relative humidity and 14:10 daily photophase. Female oviposition period, longevity and total oviposition were higher on coconut than on banana. RPM population levels tended to increase inmonthswith lowrainfall and to decrease inmonthswith high rainfall. The predator Amblyseius largoensis (Muma) (Phytoseiidae) was the only predator found associated with RPM. In general, there was a correspondence between prey and predator population trends.Dicofol caused totalmortality of R. indica,whereas nomortalitywas observedwith B. thuringiensis. Dicofol can still be used under particular situations in Cuba, e.g. in nurseries, but itswidespread use is not recommended. Further studies are required to evaluate the actual impact of A. largoensis as a control agent of R. indica, and about its possible practical application by growers, using mass produced specimens.

Siphonostomatoid copepods (Crustacea) associated with marine invertebrates and algae in Brazil: a review and future considerations
Authors: JOHNSSON RODRIGO , NEVES ELIZABETH
Published: November 2019

In Brazil, knowledge on copepods of the order Siphonostomatoida dates back to the late 1800s, with the earliest record concerning parasitic copepods of fish. In contrast, the first record in Brazil of a copepod associated with an unknown marine invertebrate did not appear until 1988, with further studies on this copepod group occurring only during the last 15 years. The aim of this paper is to summarize the knowledge on the diversity of the siphonostome copepods, focusing on the associates of marine invertebrates, and to add new data on the distribution of known species and on the utilization of host species. Finally, an evaluation is carried out on the results and the effort expended during this period, and some objectives are proposed for improving the knowledge of the siphonostome copepods associated with marine invertebrates in Brazil.
New species of Cyrtodactylus (Squamata: Gekkonidae) from Karkar Island, Papua New Guinea
Authors: KRAUS FRED , WEIJOLA VALTER
Published: November 2019

We describe a new species of Cyrtodactylus from Karkar Island, an active volcano off the northern coast of New Guinea. It is a member of the C. sermowaiensis species group, which is defined by the absence of enlarged precloacal and femoral scales and the absence of precloacal/femoral pores in males. This species group includes two other species, one of which is widespread along the northern mountain ranges of New Guinea, and the other of which is restricted to Manus Island. The new species differs from each of these in its larger size; more-tuberculate dorsum; wide, even bands across the dorsum; and uniformly brown crown of the head. Distributional data suggest that the C. sermowaiensis species group originated on the former islands of the South Caroline Arc, although only C. sermowaiensis currently occupies terranes derived from that arc. The other two species are now restricted to volcanic islands that originated independent of that arc, but the current restriction of our new species to Karkar Island seems likely to be a relictual distribution of a formerly wider range. The status of Karkar as an active volcano, and the explosive sterilization or virtual disappearance of other islands in the Bismarck Volcanic Arc, suggest that the new species could be at threat of immediate extinction should a similar explosive eruption occur on Karkar.

A Novel Epileptic Seizure Detection Algorithm Using Transfer K-Plane Clustering
Authors: Peng Lifang , Huang Bin , Chen Kefu , Zhou Leyuan
Published: November 2019

To recognize epileptic EEG signals, traditional clustering algorithms often need to satisfy three conditions to obtain better clustering results. The first condition is that the algorithm must not be sensitive to noise. The second condition is that the data set must be sufficient. The
third condition is that the training data set and the testing data set must follow the same distribution. However, in actual applications, there are few data sets that are free of noise and have sufficient data volume. To address the effects of insufficient data sets and noise on clustering,
this paper introduces fuzzy membership and transfer learning mechanisms based on K-plane clustering (KPC) and proposes a fuzzy KPC algorithm based on transfer learning (TFKPC). To improve the clustering effect, the TFKPC algorithm uses the knowledge summarized by the historical domain to guide
the clustering process of the current (target) domain when the information is insufficient. In addition, the influence of noise on the clustering result is reduced by introducing fuzzy membership. Experiments show that the TFKPC algorithm proposed in this paper has a better clustering effect
in the Epileptic Seizure Recognition Data Set than other comparison methods.
Brain Nerve Fiber Tracking Algorithm Based on Improved Optical Flow in Combination of Bayesian Prior Constraints
Authors: Jian Shen , Huan Chen , Jianjian Zuo , Xuming Pan
Published: November 2019

Diffusion Tensor Magnetic Resonance Imaging (DT-MRI) can track the brain nerve fiber and reconstruct non-invasively the three-dimensional image by tracing the local tensor orientation. The commonly used tracking method is usually based on the local diffusion information and insufficient
to consider the geometrical structure and fractional anisotropy which is constrained by anatomical structure and physiological function of human. Therefore, a novel brain nerve fiber tracking algorithm based on Bayesian optical-flow constrained framework is proposed. The construction of energy
function is the core step of global optical flow field estimation technology. In this paper, data fidelity constraint, prior constraint, penalty function and weight factor are introduced to construct Bayesian constraint function. The fiber trend model is displayed intuitively to obtain the
structure and direction of the inner nerve fibers of the brain, which can better assist in the diagnosis and treatment of clinical brain diseases, and lay a foundation for subsequent brain tissue research.

Published: November 2019

This study aimed to propose a deep transfer learning framework for histopathological image analysis by using convolutional neural networks (CNNs) with visualization schemes, and to evaluate its usage for automated and interpretable diagnosis of cervical cancer. First, in order to examine
the potential of the transfer learning for classifying cervix histopathological images, we pre-trained three state-of-the-art CNN architectures on large-size natural image datasets and then fine-tuned them on small-size histopathological datasets. Second, we investigated the impact of three
learning strategies on classification accuracy. Third, we visualized both the multiple-layer convolutional kernels of CNNs and the regions of interest so as to increase the clinical interpretability of the networks. Our method was evaluated on a database of 4993 cervical histological images
(2503 benign and 2490 malignant). The experimental results demonstrated that our method achieved 95.88% sensitivity, 98.93% specificity, 97.42% accuracy, 94.81% Youden's index and 99.71% area under the receiver operating characteristic curve. Our method can reduce the cognitive burden on pathologists
for cervical disease classification and improve their diagnostic efficiency and accuracy. It may be potentially used in clinical routine for histopathological diagnosis of cervical cancer.
Acquisition Protocols to Optimize 68Ga-DOTA-NOC Position Emission Tomography/Computer Tomography Image Quality Based on Patient Body Mass Index and Injected Dose
Authors: Xu Lei , Zhou Lei Lei , Zhao Zhenyu , Meng Qingle , Yang Rui , Jiang Hongbing , Wang Feng
Published: November 2019

Background: The choice of 68Ga-DOTA-1-Nal3-octreotide (68Ga-DOTA-NOC) injected dose and Position emission tomography/computer tomography (PET/CT) acquisition time is still a challenge for obtaining consistently high-quality PET image. Objective: To
determine the optimal acquisition protocols based on patient body mass index (BMI) and the injected dose per kilogram for 68Ga-DOTA-NOC PET/CT imaging. Patients and Methods: This was a retrospective analysis of 51 patients (21 males and 30 females) who underwent clinical
68Ga-DOTANOC PET/CT imaging from November 2016 to March 2018 in Nanjing first hospital, the average BMI of these patients was 23.18 ± 3.45 kg/m2 with injected dose of 39.55–110.11 MBq. The study population was classified into groups based on Chinese standard
BMI and injected dose. PET image quality and acquisition time were evaluated by coefficient of variance (CV) in the liver slice. Results: (1) The CV significantly increased with increasing weight and BMI (r = 0.647, 0.483, all P < 0.01), and significantly decreased
with increasing injected dose per kilogram (r = 0 695, P < 0.01). (2) The CV differed significantly among 4 BMI-based groups, except for normal-weight group versus overweight group and overweight group versus obese group (P < 0.01), and the ratio of overweight group
and obese group to normal weight group was approximately 1.1 and 1.2, respectively. Meanwhile, the CV had a significant statistical difference among 3 injected dose per kilogram groups (P < 0.01), and the ratio of that for low dose group and high dose group to moderate dose group
was approximately 1.2 and 0.8. Conclusion: The findings showed a feasibility of obtaining consistently high-quality PET image at low injected dose and shorter acquisition time. Estimation of optimal acquisition time and injected dose using CV is valid in improving PET image quality,
which can provide reference for the establishment and promotion of 68Ga-DOTA-NOC imaging protocols in China.

Provide a basis for development. Methods: A total of 34 HICH patients admitted to the hospital from January 2017 to December 2018 were included in the study. The patient was placed in the supine position with the head position raised by 0°, 15°, 30°, 45°, 0°, and
the interval between different body positions was 5 minutes. Each position was kept for 5 minutes, and the monitoring index values were read after stabilization. EGOS-600A near-infrared tissue blood oxygen parameters non-destructive monitor was used for bedside, dynamic and non-invasive real-time
monitoring of rSO2; Codman intracranial pressure monitor was used for continuous dynamic monitoring of ICP; all patients were monitored with ICP and HPM-1205A ECG The monitor measures heart rate (HR), non-invasive blood pressure (BP), and pulse oximetry (SPO2). Results:
When the bed angle of the patient was raised by 0°, 15°, 30° and 45°, the ICP value showed a decreasing trend with the elevation of the patient's bed angle. The ICP values were compared at various angles, and the difference was significant. Significance (P = 0.000);
MAP value comparison, no significant difference (P = 0.074); CPP value showed an increasing trend with the elevation of the patient's bedside angle, the difference was significant, statistically significant (P = 0.000). There was no significant difference in HR values (P =
0.470). There was no significant difference in SPO2 values (P = 0.780). Conclusion: For patients with HICH with a GCS score of 5 to 12, multi-mode neurological monitoring, supine position elevation of 15°∼30° is a relatively suitable position; HICH patients
with NIRS for rSO2 non-invasive monitoring is very Necessary, and should pay more attention to cerebral blood oxygenation changes in patients undergoing medical care after tracheotomy; use multiple modes of monitoring to ensure that patients SaO2, PaO2, MAP,
ICP, CPP, and RSO2 are within the normal range. Choosing the most effective and reliable data support for the care and treatment measures that are most beneficial to improve the cerebral ischemia and hypoxia in patients has certain clinical value.
Do All Hospital Systems Have Market Power? Association Between Hospital System Types and Cardiac Surgery Prices
Authors: Choi Sung W. , Dor Avi
Published: November 2019

Objective:

This study explores the price implications of hospital systems by analyzing the association of system characteristics with selected cardiac surgery pricing.

Data Source:

Using a large private insurance claim database, the authors identified 11 282 coronary artery bypass graft (CABG) cases and 49 866 percutaneous coronary intervention (PCI) cases from 2002 to 2007.

Study Design:

We conducted a retrospective observational study using generalized linear models.

Principal Findings:

We found that the CABG and PCI prices in centralized health and physician insurance systems were significantly lower than the prices in stand-alone hospitals by 4.4% and 6.4%, respectively. In addition, the CABG and PCI prices in independent health systems were significantly lower than in stand-alone hospitals, by 15.4% and 14.5%, respectively.

Conclusion:

The current antitrust guidelines tend to focus on the market share of merging parties and pay less attention to the characteristics of merging parties. The results of this study suggest that antitrust analysis could be more effective by considering characteristics of hospital systems.

Authors: Nikolov Aleksander , Nugteren Henk , Petrov Ognyan , Rostovsky Ivan , Petrova Tanya , Delcheva Zlatka
Published: November 2019

Natural zeolite (clinoptilolite)-based geopolymers were synthesized using alkali aluminate solution, including aluminate anodizing waste solution. The effect of calcination of the clinoptilolite sample at 900°C was investigated. The samples were studied by powder X-ray diffraction, thermal analysis, scanning electron microscopy and N2-specific surface area. The alkali aluminate-activated clinoptilolite geopolymers are characterized by satisfactory compressive strength (up to 37 MPa), low density and acceptable shrinkage. The clinoptilolite geopolymer obtained contains an X-ray amorphous phase and newly formed phillipsite and zeolite NaP. The presence of zeolite phases in the geopolymer agglomerate could be beneficial in products with specific qualities and properties, such as ion exchange, passive cooling, antimicrobial activity,etc.
Microbiota modification in hematology: still at the bench or ready for the bedside?
Authors: Severyn Christopher J. , Brewster Ryan , Andermann Tessa M.
Published: November 2019

Growing evidence suggests that human microbiota likely influence diverse processes including hematopoiesis, chemotherapy metabolism, and efficacy, as well as overall survival in patients with hematologic malignancies and other cancers. Both host genetic susceptibility and host-microbiota interactions may impact cancer risk and response to treatment; however, microbiota have the potential to be uniquely modifiable and accessible targets for treatment. Here, we focus on strategies to modify microbiota composition and function in patients with cancer. First, we evaluate the use of fecal microbiota transplant to restore microbial equilibrium following perturbation by antibiotics and chemotherapy, and as a treatment of complications of hematopoietic stem cell transplantation (HSCT), such as graft-versus-host disease and colonization with multidrug-resistant organisms. We then address the potential use of both probiotics and dietary prebiotic compounds in targeted modulation of the microbiota intended to improve outcomes in hematologic diseases. With each type of therapy, we highlight the role that abnormal, or dysbiotic, microbiota play in disease, treatment efficacy, and toxicity and evaluate their potential promise as emerging strategies for microbiota manipulation in patients with hematologic malignancies and in those undergoing HSCT.

Published: November 2019

Background

The goal for using smaller caliber instruments in PNL was to reduce the access-related complications and to decrease morbidity. The objective of this study was to evaluate the safety and efficacy of Chinese minimally invasive percutaneous nephrolithotomy (MIPNL) in the treatment of renal stones ≤ 20 mm.

Results

Sixty-seven patients completed the study protocol. The mean age was 41.10 ± 13.99 years (range 18–68 years). There were 43 (64%) male and 24 (36%) females. The mean stone size was ranged from 78.5 to 439.6 mm2(mean ± SD 172.48 ± 69.54 mm2). The overall SFR was (82%). Twelve (18%) needed post-MIPNL auxiliary procedure, in the form of second MIPNL in 3 (4.5%) cases, SWL in 7 (10%), and RIRS in 2 (3%) cases. The intraoperative complication was present in four patients (5%) include bleeding necessitate blood transfusion in one patient (1.5%) and renal collecting system perforation 3 (4.5%). The postoperative complication was urine leakage 5 (7.5) and fever in 6 (9%) of patients.

Conclusion

Chinese MIPNL is safe and effective method for treatment of renal stone ≤ 20 mm size with satisfactory SFR and low complication rate when SWL failed or contraindicated. It is considered a feasible treatment alternative to standard PNL, in the absence of flexible URS or miniature nephroscope.

Published: November 2019

Background

Pachycladon cheesemanii is a close relative of Arabidopsis thaliana and is an allotetraploid perennial herb which is widespread in the South Island of New Zealand. It grows at altitudes of up to 1000 m where it is subject to relatively high levels of ultraviolet (UV)-B radiation. To gain first insights into how Pachycladon copes with UV-B stress, we sequenced its genome and compared the UV-B tolerance of two Pachycladon accessions with those of two A. thaliana accessions from different altitudes.

Results

A high-quality draft genome of P. cheesemanii was assembled with a high percentage of conserved single-copy plant orthologs. Synteny analysis with genomes from other species of the Brassicaceae family found a close phylogenetic relationship of P. cheesemanii with Boechera stricta from Brassicaceae lineage I. While UV-B radiation caused a greater growth reduction in the A. thaliana accessions than in the P. cheesemanii accessions, growth was not reduced in one P. cheesemanii accession. The homologues of A. thaliana UV-B radiation response genes were duplicated in P. cheesemanii, and an expression analysis of those genes indicated that the tolerance mechanism in P. cheesemanii appears to differ from that in A. thaliana.

Conclusion

Although the P. cheesemanii genome shows close similarity with that of A. thaliana, it appears to have evolved novel strategies allowing the plant to tolerate relatively high UV-B radiation.

Published: November 2019

Background

As health behavior varies with increasing age, we aimed to examine the potential barriers in calling emergency medical services (EMS) after recognizing a stroke among 40–74- and 75–99-year-old adults.

Methods

Data were obtained from a cross-sectional community-based study (FAST-RIGHT) that was conducted from January 2017 to May 2017 and involved adults (age ≥ 40 years) across 69 administrative areas in China. A subgroup of residents (153675) who recognized stroke symptoms was analyzed. Multivariable logistic regression models were performed in the 40–74 and 75–99 age groups, separately, to determine the factors associated with wait-and-see behaviors at the onset of a stroke.

Results

In the 40–74 and 75–99 age groups, the rates of participants who chose “Self-observation at home” were 3.0% (3912) and 3.5% (738), respectively; the rates of “Wait for family, then go to hospital” were 31.7% (42071) and 33.1% (6957), respectively. Rural residence, living with one’s spouse, low income (< 731 US $ per annum), having a single avenue to learn about stroke, and having friends with stroke were factors associated with waiting for one’s family in both groups. However, unlike in the 40–74 age group, sex, number of children, family history, and stroke history did not influence the behaviors at stroke onset in the 75–99 age group.

Conclusions

Different barriers from recognizing stroke and calling an ambulance exist in the 40–74 and 75–99 age groups in this specific population. Different strategies that mainly focus on changing the “Wait for family” behavior and emphasize on immediately calling EMS are recommended for both age groups.
Spectrum of clinical features and neuroimaging findings in acute cerebral infarction patients with unusual ipsilateral motor impairment– a series of 22 cases
Authors: Tan Zhe-Ren , Zhang Chen , Tian Fa-Fa
Published: November 2019

Background

Cerebral infarction occurs when the arteries to brain are obstructed, and motor impairment contralateral to responsible lesion is commonly recognized. Few studies have profiled the characteristics of cases with ipsilateral motor impairment. We sought to characterize clinical features of patients with motor dysfunction caused by ipsilateral ischemic stroke.

Methods

We retrieved and analyzed the medical data for patients with ipsilateral cerebral infarction. Patients were regarded as having ipsilateral cerebral infarction if motor impairment is ipsilateral to recent stroke lesions.

Results

Only 22 patients with unusual ipsilateral cerebral infarction were included in this study. Ipsilateral limb paralysis was observed in all cases, and one case showed central facioplegia. Majority of patients with limb paralysis (90.9%, 20/22) presented with mild muscle strength deficits (MRC grading of 4 or more). Most of the patients (72.7%, 16/22) had a past history of stroke, and previous strokes were contralateral to the side of the recent stroke in 14 out of 16 patients (87.5%). No history of stroke or cerebral injury was identified in seven patients. With aspect of MRI findings, recent infarct lesions of all cases were located along the corticospinal tract.

Conclusions

History of stroke plays an important role in the pathogenesis of ipsilateral motor impairment, and cortical reorganization in the unaffected hemisphere may contribute to the compensation of motor function after stroke. Besides that, some cases with first stroke may be due to impairment of ipsilateral uncrossed corticospinal fibers.

Published: November 2019

Background

Corneal transplantations are surgeries performed for irreparable corneal diseases and damage. However, there is a gap between the number of potential recipients and the number of donor corneas available. The main aim of the study was to determine the awareness and attitudes toward corneal donation among applicants and staff of DVLA, Kumasi-Ghana.

Methods

A descriptive cross-sectional study was conducted. One hundred participants were selected using convenient sampling method. A structured questionnaire was used to elicit responses from participants concerning awareness and attitudes toward corneal transplant.

Results

The mean ± SD age of the participants was 32.05 ± 11.48 years and age range, 18-67 years. Males were 66% whilst females constituted 34%. 32.7% of the participants were aware of corneal donation. Majority of the participants were Christians (83.1%) and Singles (63%). Television was the source of information with the highest preponderance (49.4%). 67.3% were willing to donate their corneas after death. 63.9% were willing to indicate their donor statuses on drivers’ license form which had a significant association with willingness to donate cornea after death (p < 0.05,x2 = 12.187).

Conclusion

There is a poor level of awareness (32.7%) of transplant and donation amongst the study population but a good level of willingness to donate organs (67%). Consent via driving license would seem to be a good potential mode of obtaining consent to supplement the harvesting of adequate tissues for transplant if adequate awareness is created.
