Posterior mediastinal Castleman’s disease with vascular malformation
Authors: Tamire Ayalew T. 
Published: April 2021

Castelman’s disease (CD) is a rare lymphoproliferative disorder of unknown aetiology, with the unicentric form usually involving the chest. Posterior mediastinal involvement is uncommon, exceedingly so when associated with vascular malformation. We report the case of a young female patient who presented with 9 months of left-sided, dull chest and flank pain associated with weight loss and a subjective tingling sensation. Imaging reveled a well-circumscribed hyper-enhancing posterior mediastinal para-oesophageal mass. She underwent a right posterolateral thoracotomy, mass excision. Histopathologic examination confirmed Castleman’s disease (CD) with arteriovenous malformation. CD with vascular malformation is a very rare condition that can only be diagnosed histopathologically. Surgical resection is effective and has a good prognosis. Keywords: Castleman’s disease; AV malformation; posterior mediastinum
Prevalence of acute deep vein thrombosis according to HIV status following major orthopaedic surgery at the University Teaching Hospital, Lusaka, Zambia
Authors: West Collin , Mulla Yakub , Munthali James 
Published: April 2021

Background: Hypercoagulable states and immobilization following lower limb, pelvic, and spinal surgery increases the risk of deep vein thrombosis (DVT). It is also suggested that HIV alone increases the risk of deep vein thrombosis. However no study has been done to determine the prevalence of deep vein thrombosis in HIV seropositive individuals who have undergone lower limb orthopaedic surgery in the Zambian context. We therefore conducted this study to determine the prevalence of deep vein thrombosis in patients who are HIV seropositive in comparison to those who are HIV seronegative after undergoing lower limb orthopaedic surgery. Methods: A total of 42 Patients were enrolled. Of these 23 (54 %) were HIV negative controls and 19 (46 %) were HIV positive patients who underwent lower limb surgery or spinal surgery. Demographic and HIV status data was collected prior to surgery. After surgery a blood sample was tested for fibrinogen degradation products (D-dimer) levels. The patients were then monitored for the development of clinical DVT and those that developed clinical DVT had an ultrasound to confirm the diagnosis. Results: The majority (81%) of the study population were under the age of 50 years. The mean values of D-dimers were 2.33 ± 1.65 μg/ml for the HIV negative group and 2.55 ±1.50 μg/ml for the HIV positive group. The number of positive D-dimer results was similar in the two groups, 94.7% for the HIV cohort and 95.7% in the negative group (X 2 0.19 p=0.89). There was a positive correlation between the D-dimer value and the type of surgery done in both the HIV positive group (R 0.390 p = 0.049) and the HIV negative group (R 0.398 at p = 0.03). In both group’s hip and knee surgeries gave higher values of D-dimers. There was no statistical difference in the occurrence of a positive D-dimer and CD4 count (X2 0.95 p=0.89). The combined prevalence of clinical DVT confirmed by compression ultrasonography in the entire study population was 4.8%. The prevalence in the HIV seropositive group and HIV seronegative groups were 5.3% and 4.3% respectively (X2 0.19 p= 0.89). None of the patients received preoperative DVT prophylaxis due to cost but both patients that developed DVT received antithrombotic treatment. Conclusions: There was no significant difference in the prevalence of DVT between patients who were HIV seronegative and seronegative following major lower limb and spinal orthopaedic surgery. Both groups had raised D-dimer values. Keywords: deep vein thrombosis; HIV; D-dimer; Doppler ultrasound

Published: April 2021

Quantifying insect respiratory structures and their variation has remained challenging due to their microscopic size. Here we measure insect tracheal volume using X-ray micro-tomography (μCT) scanning (at 15 μm resolution) on living, sedated larvae of the cerambycid beetle Cacosceles newmannii across a range of body sizes. In this paper we provide the full volumetric data and 3D models for 12 scans, providing novel data on repeatability of imaging analyses and structural tracheal trait differences provided by different image segmentation methods. The volume data is provided here with segmented tracheal regions as 3D models.

Published: April 2021

Abstract. Secondary organic aerosols (SOAs) affect human health and
climate change prediction; however, the factors (e.g., temperature, acidity
of pre-existing particles, and oxidants) influencing their formation are not
sufficiently resolved. Using a compact chamber, the temperature and acidity
dependence of SOA yields and chemical components in SOA from α-pinene ozonolysis were systematically investigated under 278, 288, and
298 K temperatures using neutral ((NH4)2SO4) and acidic
(H2SO4+((NH4)2SO4)) seed aerosols. SOA components
with m/z less than 400 were analyzed using negative electrospray ionization
liquid-chromatography time-of-flight mass spectrometry. Based on the
slightly negative temperature dependence of the SOA yields, the enthalpies
of vaporization under neutral and acidic seed conditions were estimated to
be 25 and 44 kJ mol−1, respectively. In addition, SOA yields increased
with an increase in the acidity of seed particles (solid/near-solid state)
at low SOA mass loadings, when compared with the seed particle amounts.
Acidity dependence analysis of the chemical formula, molecular mass, and O:C
ratio of the detected compounds indicated the enhanced formation of multiple
oligomers in the wide molecular mass range with a wide range of O:C ratios
under acidic seed conditions. The peak abundances of some chemical compounds
increased with an increase in the acidity of seed particles (e.g., m/z 197,
311, 313, 339, 355, and 383), while decreases in the peak abundances of some
chemical compounds were observed (e.g., m/z 171, 185, 215, 343, and 357). The
acidity dependence could be explained by acid-catalyzed heterogeneous
reactions or acid-catalyzed decomposition of hydroperoxides. In addition,
organosulfate (OS) formation was observed under acidic seed conditions. Six
out of the 11 detected OSs were potentially formed via the aldehyde +
HSO4- pathway.
A generalized Spatio-Temporal Threshold Clustering method for identification of extreme event patterns
Authors: Kholodovsky Vitaly , Liang Xin-Zhong 
Published: April 2021

Abstract. Extreme weather and climate events such as floods, droughts, and heat waves can cause extensive societal damages. While various statistical and climate models have been developed for the purpose of simulating extremes, a consistent definition of extreme events is still lacking. Furthermore, to better assess the performance of the climate models, a variety of spatial forecast verification measures have been developed. However, in most cases, the spatial verification measures that are widely used to compare mean states do not have sufficient theoretical justification to benchmark extreme events. In order to alleviate inconsistencies when defining extreme events within different scientific communities, we propose a new generalized Spatio-Temporal Threshold Clustering method for the identification of extreme event episodes, which uses machine learning techniques to couple existing pattern recognition indices with high or low threshold choices. The method consists of five main steps: (1) construction of essential field quantities; (2) dimension reduction; (3) spatial domain mapping; (4) time series clustering; and (5) threshold selection. We develop and apply this method using a gridded daily precipitation dataset derived from rain gauge stations over the contiguous United States. We observe changes in the distribution of conditional frequency of extreme precipitation from large-scale well-connected spatial patterns to smaller-scale more isolated rainfall clusters, possibly leading to more localized droughts and heat waves, especially during the summer months. The proposed method automates the threshold selection process through a clustering algorithm and can be directly applicable in conjunction with modeling and spatial forecast verification of extremes. Additionally, it allows for the identification of synoptic-scale spatial patterns that can be directly traced to the individual extreme episodes, and it offers users the flexibility to select an extreme threshold that is linked to the desired geometrical properties. The approach can be applied to broad scientific disciplines.

Authors: Thurai Merhala , Bringi Viswanathan , Gatlin Patrick , Wingo Mathew 
Published: April 2021

Abstract. Laboratory measurements of drop fall speeds by Gunn–Kinzer under still air conditions with pressure corrections of Beard are accepted as the “gold standard”. We present measured fall speeds of 2 and 3 mm raindrops falling in turbulent flow with 2D-video disdrometer (2DVD) and simultaneous measurements of wind velocity fluctuations using a 3D-sonic anemometer. The findings based on six rain events are, (i) the mean fall speed decreases (from the Gunn–Kinzer terminal velocity) with increasing turbulent intensity, and (ii) the standard deviation increases with increase in the rms of the air velocity fluctuations. These findings are compared with other observations reported in the literature.

Published: April 2021

Abstract. The present study is to explore the potential relationship between debris flow and landslides by establishing susceptibility zoning maps (SZMs) separately with the use of random forest (RF). Lhünzê county, located in southeastern Tibet, was selected as the study area. The work was carried out with the following steps: (1) an inventory map consisting of 399 landslides and 49 debris flows was determined; (2) slope units and 11 conditioning factors were prepared for the susceptibility modeling of landslide while watershed units and 12 factors were prepared for debris flow; (3) SZMs were constructed for landslide and debris flow, respectively, with the use of RF; (4) the performance of two models was evaluated by 5-fold cross-validation using receiver operating characteristic (ROC), area under the curve (AUC) and statistical measures; (5) the potential relationship between landslide and debris flow was explored by the superimposition of two zoning maps; (6) the Gini index was applied to determine the major factors
and analyze the difference between debris flow and landslides; (7) a combined susceptibility map with two considered hazardous phenomena was
obtained. Two used models had demonstrated great predictive capabilities, with an accuracy of 87.33 % and 85.17 % and AUC of 0.902 and 0.892, respectively. Comparing the overlap of different susceptibility classes for two obtained maps, it was concluded that there is no straightforward relationship between the occurrence of debris flow and landslides. Although most landslides can be converted into debris flow, the area prone to debris flow did not promote the occurrence of a landslide. A susceptibility zoning map composed of two or more hazardous phenomena is comprehensive and significant in this regard, which provides a valuable reference for research studies of disaster-chain and engineering applications.

Ayurved is science of life having aim to maintain the health and eradication of the diseases. Anukta is one of the time tested principle of the Ayurveda, which give us the directions to understand the newly formed diseases, Anukta vyadhi are those vyadhi which are not explained in the samhita. Acharya Charaka mentioned that all diseases cannot labeled with some name, Unsaid diseases can be studied as a kupit dosha, hetu, and their sthan. Acharya chakrapani comments that Atidesha tantraukti is useful to getting the knowledge of unsaid/ hidden things. Ayurvedic classics advocate the concepts of the Anukta vyadhi. In a present era so many newly formed diseases are exiting which are not explained in ayurved classics, concept of trividha bodhya sangraha i.e. Vikar Prakruti-Adhisthana-Samuthana is useful to study the newly formed diseases. Here attempt is made to elaborate the concepts of anukta vyadhi and its diagnostic approach.

Permanent cessation of menstruation at the end of reproductive life due to loss of ovarian follicular activity. Complete stoppage of menstruation for twelve consecutive months without any other pathology. Around 45 to 55 yrs averages. But now a days the age of menarche and menopause is changing to 12 yr to around 40 to 45 yrs due to changing life style of females. Pranayama serves as the link between the consciousness and the mind .it is breating technique which help in stress and relaxation. This helps the women to focus on the simplicity of movement and get about work responsibility and demands thus reduce anxiety as well as depression.
