Use of the Growth Hormone Stimulation Test Result in the Management of Patients With a Short Stature

Introduction A proportionate short stature (SS) assessment involves the documentation of normal growth hormone secretion via a growth hormone (GH) stimulation test. All available GH stimulation tests have some disadvantages. The decision to initiate GH therapy is dependent on multiple factors, including the GH stimulation test result. However, many patients receive GH therapy, even if they have a normal GH stimulation test result, with the indication of a presumed idiopathic SS. Objective In this study, we investigated the use of the GH stimulation test result in initiating GH therapy. Method A cross-sectional study was conducted with patients diagnosed with proportionate SS. Age, gender, insulin-like growth factor 1 (IGF-1) level, and GH stimulation test results were collected retrospectively from the electronic medical records. The main outcome variable was the decision related to prescribing GH therapy. Results A total of 286 patient charts were reviewed, and the majority (n = 201, 64.6%) were male. For just less than half (n = 136, 47.6%), the result of the GH stimulation test was ≥ 10 ng/mL, in a small proportion (n = 53, 18.5%) the result was < 5 ng/mL, and for the rest of the cohort, the result was 5.0 - 9.9 ng/mL. The majority (n = 219, 70.4%) received GH therapy, irrespective of the GH stimulation test result. The odds ratio (OR) for GH treatment was 3.9 (CI: 1.79 - 8.49) and 3.0 (CI: 1.21 - 7.42) for patients with a result < 5 ng/mL and 5.0 - 9.9 ng/mL, respectively, compared to the group with a result of ≥ 10 ng/mL. Conclusion GH therapy is frequently prescribed for patients with SS, irrespective of the GH stimulation test result. However, the group with SS with a result of < 9.9 ng/mL was more likely to receive GH therapy. The question of whether a GH stimulation test is required, in the context of SS, is debatable.
Contextual Reserve Price Optimization in Auctions

We study the problem of learning a linear model to set the reserve price in order to maximize expected revenue in an auction, given contextual information. First, we show that it is not possible to solve this problem in polynomial time unless the \emph{Exponential Time Hypothesis} fails. Second, we present a strong mixed-integer programming (MIP) formulation for this problem, which is capable of exactly modeling the nonconvex and discontinuous expected reward function. Moreover, we show that this MIP formulation is ideal (the strongest possible formulation) for the revenue function. Since it can be computationally expensive to exactly solve the MIP formulation, we also study the performance of its linear programming (LP) relaxation. We show that, unfortunately, in the worst case the objective gap of the linear programming relaxation can be $O(n)$ times larger than the optimal objective of the actual problem, where $n$ is the number of samples. Finally, we present computational results, showcasing that the mixed-integer programming formulation, along with its linear programming relaxation, are able to superior both the in-sample performance and the out-of-sample performance of the state-of-the-art algorithms on both real and synthetic datasets.

Phylogenetic and phylogeographic patterns of Didymosphenia geminata on invaded sites in Chile

Understanding the population dynamics of invasive processes has become a pressing concern in a highly connected world faced with ongoing climate change and increased exotic species introduction. In Chile, the invasive freshwater benthic diatom Didymosphenia geminata (Lyngbye) Schmidt has become widespread, expanding across multiple river basins spanning over 3000 km in three years. Here we evaluate the phylogenetic and phylogeographic relationships of D. geminata samples collected throughout the invaded range in Chile, using specific rbcL gene sequence previously published. Genetic sequences for this marker were generated for 19 sample sites, and were compared with available freshwater diatom sequences, as well as with previously published rbcL gene sequences for D. geminata. We find that all genetic sequences collected within Chile present phylogenetic divergences from D. geminata samples collected in Siberia, as well as from samples of the genera Gomphonema, Cymbella and Encyonema. Thus, we validate the invasion by D. geminata, in agreement with existing morphological taxonomic criteria. In addition, a haplotype analysis showed a total of 13 haplotypes, two of which (halpotypes I and IX) found in 12 and 3 populations respectively, while each of the remaining haplotypes presents a single population. Thus, these results are consistent either with the introduction of multiple lineages, or with a rapid genetic differentiation in this invading freshwater diatom. Further genetic sampling, both within Chile and in countries that may have been potential sources of the invasion are needed to test these alternative hypotheses.
Heavy metals uptake and translocation by lettuce and spinach grown on a metal-contaminated soil

Nowadays, using sewage wastewaters in the irrigated agriculture is commune creating hazardous environment impacts. Assessment of these negative effects is vital issue to prevent heavy metals to be introduced in the food chain. Field and laboratory studies were conducted at Arab-El-Madabegh village, Assiut Governorate, Egypt, in order to evaluate the heavy metals concentrations in the edible parts of lettuce and spinach plants which irrigated with sewage water (SW). The obtained results indicated that, the soils of the studied site were contaminated by heavy metals. Zinc, Cu, Pb, Cd and Ni concentrations in the edible portions of the studied vegetables plants ranged between 75110, 15 17, 2 5, 1.0 -3.5 and 1.0 -2.5 mg kg−1, respectively. The obtained results showed that the concentrations of Zn, Pb, Cd and Ni in the edible parts of the studied plants were higher than the permissible limit levels but those of Cu were within the safe limit levels. It is worthy to mention that the irrigated edible vegetable crops with SW should be avoided. This study highlights the potential hazard for human health due to the uptake of high concentrations of heavy metals especially Zn, Ni, Cd and Pb by the studied vegetable crops .
Nutritional Dietary Supplements to Reduce the Incidence of Fatty Liver Syndrome in Laying Hens and the Use of Spectrophotometry to Predict Liver Fat Content

SUMMARY Fatty liver syndrome (FLS) in laying hens is a metabolic disease that can potentially reduce egg production while compromising the health status of the bird. This study assessed the combined use of B vitamins via the feed (FLS-MIX) or the drinking water (FLS-LIQ) to reduce FLS and the use of spectrophotometry to estimate liver fat content. Individually, caged Hy-line brown hens (n = 288) underwent a pre-experimental period (from week 66 to 67, both included) receiving a Standard diet or a Challenge diet (high energy–low protein) to nutritionally induce the FLS. Subsequently, hens followed a 2 diets (Standard; Challenge) × 3 dietary supplements (NONE; FLS-MIX; and FLS-LIQ) factorial arrangement of treatments from 68 to 73 wk old, both included. Compared to the Standard, the Challenge diet increased liver fat (188 vs. 270 g/kg DM) and reduced feed consumption, lay percentage, and egg mass production (P
Investigation on awareness and influencing factors of HPV self-sampling for cervical cancer screening of female in Shenzhen

Objective To investigate awareness and influencing factors of human papilloma virus (HPV) self-sampling for cervical cancer screening of female in Shenzhen. Methods A total of 544 female, who during July 2014 to June 2015, participated in live and online HPV self-sampling detection organized by our hospital, were surveyed by self-designed questionnaire. Their epidemiological data, HPV and cervical cancer related knowledge, awareness of HPV self-sampling for cervical cancer screening, their attitude, willingness and acceptance to HPV self-sampling for cervical cancer screening were investigated. Effects of awareness of HPV self-sampling to the cervical cancer screening and main influencing factors were analyzed. Results Among the 544 women, 47.1% were aware of HPV; 22.8% were aware of what diseases could be caused by HPV; 12.5% had heard of and done by themselves self-sampling for cervical cancer screening; only 6.3% had heard of and participated in online self-sampling for cervical cancer screening. Women, who were enterprise/corporate white collar/independent enterprise manager or whose monthly income was over 30, 000 yuan, were less aware of HPV self-sampling than other women (χ2=13.058, 12.626; P<0.05). 81.6% of the female were apparently inclined to be sampled by doctors, and only 7.0% of the female believed that credibility of self-sampling screening was above 80%. The biggest concern about online self-sampling was mainly metamorphic specimens during transport, pollution, etc. Conclusions Awareness of female in Shenzhen about HPV and HPV self-sampling cervical cancer screening are relatively low. Intervention should be emphasized in reliability degree of self-sampling result, discomfort degree of sampling, complexity, specimen preservation, transport and result feedback.

Low Complexity Iterative Rake Decision Feedback Equalizer for Zero-Padded OTFS Systems

This paper presents a linear complexity iterative rake detector for the recently proposed orthogonal time frequency space (OTFS) modulation scheme. The basic idea is to extract and coherently combine the received multipath components of the transmitted symbols in the delay-Doppler grid using maximal ratio combining (MRC) to improve the SNR of the combined signal. We reformulate the OTFS input-output relation in simple vector form by placing guard null symbols or zero padding (ZP) in the delay-Doppler grid and exploiting the resulting circulant property of the blocks of the channel matrix. Using this vector input-output relation we propose a low complexity iterative decision feedback equalizer (DFE) based on MRC. The performance and complexity of the proposed detector favorably compares with the state of the art message passing detector. An alternative time domain MRC based detector is also proposed for even faster detection. We further propose a Gauss-Seidel based over-relaxation parameter in the rake detector to improve the performance and the convergence speed of the iterative detection. We also show how the MRC detector can be combined with outer error-correcting codes to operate as a turbo DFE scheme to further improve the error performance. All results are compared with a baseline orthogonal frequency division multiplexing (OFDM) scheme employing a single tap minimum mean square error (MMSE) equalizer.
AID: Pushing the Performance Boundary of Human Pose Estimation with Information Dropping Augmentation

Both appearance cue and constraint cue are vital for human pose estimation. However, there is a tendency in most existing works to overfitting the former and overlook the latter. In this paper, we propose Augmentation by Information Dropping (AID) to verify and tackle this dilemma. Alone with AID as a prerequisite for effectively exploiting its potential, we propose customized training schedules, which are designed by analyzing the pattern of loss and performance in training process from the perspective of information supplying. In experiments, as a model-agnostic approach, AID promotes various state-of-the-art methods in both bottom-up and top-down paradigms with different input sizes, frameworks, backbones, training and testing sets. On popular COCO human pose estimation test set, AID consistently boosts the performance of different configurations by around 0.6 AP in top-down paradigm and up to 1.5 AP in bottom-up paradigm. On more challenging CrowdPose dataset, the improvement is more than 1.5 AP. As AID successfully pushes the performance boundary of human pose estimation problem by considerable margin and sets a new state-of-the-art, we hope AID to be a regular configuration for training human pose estimators. The source code will be publicly available for further research.
Distributed Incremental Strategy for Radio Tomographic Imaging

Radio Tomographic Imaging (RTI) finds extensive application in modern day problem. The RTI achieved this using received signal strength (RSS) power and transmitted power by sensor nodes. RTI being an ill-posed inverse problem, requires regularization for proper estimation of spatial loss field(SLF) and able to detect the object. Centralized solution of RTI system requires large communication overheads. This motivates to develop distributed algorithm for RTI. Two novel distributed algorithms using incremental approach are developed in this paper. The first approach is the direct extension of the centralized approach to distributed incremental approach. Second algorithm requires less communication overheads compared to the first one by incorporating data censoring technique. The performance metrics show that the performance of distributed Incremental RTI is comparable to the centralized RTI system. Again the impact of censoring is studied by increasing the censoring ratio , which results in a trade-off between detection performance and computational complexity.
Value of early-phase enhancement ratio combined with peripheral vascular diameter in the differential diagnosis of benign and malignant breast lesions under dynamic contrast enhanced MRI

Objective To investigate the value of early- phase enhancement ratio combined with peripheral vascular diameter in the differential diagnosis of benign and malignant breast lesions using 3.0 T dynamic contrast - enhanced magnetic resonance imaging (DCE - MRI). Methods Sixty seven cases of patients (35 with malignant lesions and 32 with benign lesions in the breasts) were retrospectively analyzed. Their diagnoses were confirmed by surgery and pathology and all the patients underwent breast MRI plain scan and DCE - MRI in the two weeks before surgery. Lesion ROIs were drawn and time - signal intensity curves in the DCE-MRI were generated. Early-phase enhancement rate, time to peak, early-phase enhancement ratio, numbers of tumor vessel within 3 cm of the lesion and diameter of the largest vessel were recorded. Mann - Whitney U test was used to compare the difference of DCE - MRI between benign and malignant lesions, and the ROC curve was used to evaluate the efficiency of early-phase enhancement rate, early-phase enhancement ratio and vascular diameter in differentiating benign and malignant lesions. Results With breast malignant lesions, the medians of time to peak, early-phase enhancement rate, early- phase enhancement ratio, numbers of tumor vessel and vascular diameter were 2.2 s, 176.0%, 100.0%, 4 and 2.96 mm respectively, while with benign lesions of these parameters were 4.7 s, 113.3%, 81.9%, 0 and 0.00 mm respectively, and the differences were statistically significant (all P<0.05). When early-phase enhancement rate was used for differential diagnosis of breast benign and malignant lesions, the area under the ROC curve was 0.702 and the sensitivity and specificity were 82.86% and 56.25% with a threshold of 120.0%. When early-phase enhancement ratio was used, the area under the ROC curve was 0.854 and the sensitivity and specificity were 94.29% and 68.75% with a threshold of 86.0%. When peripheral vascular diameter was used, the area under the ROC curve was 0.896 and the sensitivity and specificity were 74.29% and 84.38% with a threshold of 2.78 mm. When early-phase enhancement ratio was combined with peripheral vascular diameter, the area was 0.925 and the sensitivity and specificity were 97.14% and 62.50%. Conclusion In the differential diagnosis of benign and malignant breast lesions under DCE-MRI, early-phase enhancement ratio combining with peripheral vascular diameter has improved sensitivity.

Genotype by Environmental Interaction Effects on LayingCharacteristics of Lohman Brown in Sub-Humid Tropics ofNigeria

Layers are sexually mature female birds raised for egg production. A layer is a hen in its physiological state of regularly egg production (Sastry and Thomas 2010; Damron, 2009 and Taneja et al., 2008). Egg laying starts at 20 weeks of age, progresses and rises to a peak and remained economical up to 72 to 75 weeks and begins to decline with advance in age. When the egg production goes below the economical level or the breakeven point, the birds are culled (Sastry and Thomas, 2010). According to Taneja et al. (2008), layer flocks should be transfers from grower house to layer house at 18 to 20 weeks of age. At 18 weeks of age, all under grown pullets are to be cull from the flock. Careful selection at the time of housing enables better returns and fewer cull at point of first egg production (Sastry and Thomas,2010). The stock can either be reared in the same house where it was brooded /reared or transferred to the laying house. Sastry and Thomas, ( 2010) stated that the laying period, also called laying cycle or biological year is when the birds reach 5% egg production on henday basis and continues to the end of the birds laying age. The age at which a hen begins to lay eggs affects the total egg production in its life cycle (Dafwang, 1987). According to Sastry and Thomas, (2010) selection of laying hens is normally based on partial records, improvement in egg production occurs largely in the first part of the laying cycle. Brown (2010) recommended that most profitable way for layer production is to follow “all in, all out” practice. Urban populations are rapidly growing throughout the tropics and there is need to equally increases poultry production. ABSTRACT

Gastrointestinal Stromal Tumor Inside a Jejunal True Diverticulum

Background: True diverticulum and malignant tumors are rare conditions of jejunum. This is the first published case of a Gastrointestinal Stromal Tumor (GIST) inside a true jejunal diverticulum. Case Report: A59-year-old male presented a sudden abdominal pain with emesis and abdominal distension. Computed tomography of the abdomen revealed a mechanical bowel obstruction caused by a tumor in the small bowel. At laparotomy, an isolated 8.0 cm × 4.5 cm jejunal diverticulum with a perforated tumor was found, about 80 cm from the Treitz ligament. The tumor was removed, as were the segment of the jejunum containing the isolated diverticulum and its correspondent mesentery, including the local lymph nodes. The histologic examination of the tumor revealed a GIST with no lymph node metastasis. After one year, the patient presented a new small bowel obstruction due to six nodules surrounding a jejunoileal segment, far from the first anastomosis. All nodules and a twenty-centimeter-jejunoileal segment were removed. GIST was diagnosed in five nodules. The patient was discharged from the hospital in good conditions on the third postoperative day. During the 38-month-follow-up from the second procedure, no adverse event has been identified. The patient is working, presents no complaints, and is under control with 800 mg imatinib. Conclusion: A GIST may be found inside a jejunal true diverticulum. The treatment must be an en bloc resection of the diverticulum with a segment of jejunum and its mesentery, including all lymphatic tissue. Adjuvant imatinib chemotherapy is indicated to prevent recurrences.
Biocatalysis:Biochemical Fundamentals and Applications

The book covers the fundamentals of the field of biocatalysis that are not treated in such detail (or even not at all) in existing biocatalysis books or biochemistry textbooks. It of course does not substitute existing biochemistry textbooks but will serve a suitable supplement as it discusses biochemical fundamentals in connection with the respective topics.With focus on the interdisciplinary nature of biocatalysis, the book contains many aspects of fundamental organic chemistry and some of inorganic chemistry as well, which should make it interesting not only for biochemistry but also for chemistry students. An important theme being emphasized in the book is that applied biocatalysis is one of the main prerequisites for a sustainable development.The topics covered ranges from basic enzyme chemistry (biosynthesis, structure, properties, interaction forces, kinetics) to a detailed description of catalytic mechanisms. It covers the fundamentals of the different enzyme classes together with their applications in native and in immobilized state or in the form of whole cells in aqueous as well as non-conventional media. Topics such as catalytic antibodies, nucleic acid catalysts, non-ribosomal peptide synthesis, evolutionary methods, and the design of cells are also included.
