Background: Early Childhood Adversity (ECA) explains the presence of psychological issues such as depression in many chronic disease settings but has not been measured in lung cancer. ECA may increase the positive predictive value for detecting lung cancer related psychological problems. ECA is associated with inflammation in adulthood independent of psychological outcomes or other chronic diseases. Similarly, depression is associated with inflammation. Patients with lung cancer have elevated physical symptoms, which are increased in the presence of depression, but have not been measured in the presence of ECA. We hypothesized that psychological issues and physical symptoms are worse in lung cancer patients who experienced ECA and that this relationship is explained by inflammation. Methods: Patients with stage IV lung cancer (n = 92) were evaluated for ECA using the Risky Families Questionnaire. Concomitant assessments were made of distress (Distress Thermometer and Problem List [DT&PL]), anxiety (Generalized Anxiety Disorder-7), depression (Patient Hospital Questionniare-9), physical symptoms (DT&PL), and inflammation (C-reactive protein [CRP]). Multivariate models were created to explain associations with depression, anxiety, and distress. Results: ECA was associated with younger age (p = .006), elevated CRP (p = .042), distress (p = .032), anxiety (p = .004), depression ( = .001) and greater physical problems (p = .025). Multivariate analyses of psychological outcomes found that ECA (p = .017) explained depression severity, but not distress or anxiety, while controlling for age, sex, and physical symptoms. No interaction effects were seen between inflammation, physical symptoms, and ECA. Conclusions: ECA places lung cancer patients at a higher risk of developing depression, which complicates lung cancer treatment, quality of life, and overall survival outcomes. ECA should be factored into lung cancer patient psychological assessments.

Background: Patients with advanced cancer who have minor children face unique challenges when coping with their life-limiting illness and the impact of their illness on their families. The goal of this study was to examine whether psychosocial functioning, treatment preferences, and treatment decisions in advanced cancer differ by parental status. Methods: A cohort of 60 parents with metastatic solid tumors age-matched with 60 non-parents (N = 120) participated in three structured interviews assessing treatment preferences and decisions over six months with complementary medical record review. Participants also completed validated measures of psychosocial functioning. Results: Seventy percent (n = 85) of the sample completed all study assessments. Mean age (45 years, SD 8), mean performance status score (ECOG = 1.2, SD 0.9), median duration of metastatic illness (19 months, range 1-115), gender ratio (66% female), and dropout rates were similar between groups. Parents and non-parents reported similar overall health-related quality of life, but parents were more likely to report poorer emotional well-being (p = 0.006) and more symptoms of depression (p = 0.04) and anxiety (p = 0.04) than non-parents. Parents and non-parents were equally likely to describe life-extension as their primary goal of anti-neoplastic treatment. Parents reported greater willingness to live in pain (48% “very willing” vs 27%, p = 0.007) and accept intubation/ventilation (40% vs 20%, p = 0.01) for life-extension. Compared to non-parents, parents were more likely to report their family members as the most influential factor in their decision-making (44% vs 12%) and less likely to cite their oncologist’s recommendation (25% vs 41%). There were no significant differences between groups for completion of a health care power of attorney or living will. Conclusions: Compared to similarly aged adults with metastatic cancer, parents experience greater psychological distress, are more willing to live in pain for life extension, and place greater importance on family-related factors in their cancer treatment decision-making.

Background: Electronic patient-reported outcomes (ePROs) can improve quality of life and prolong survival in patients with cancer by enhancing the detection and tracking of unmet supportive care needs. However, there remain unanswered questions about how to handle missing ePRO data. We hypothesized that patients may skip specific questions they feel do not apply to them. We aimed to examine the relationship between patient demographics and missing items in a real-world ePRO dataset. Methods: We utilized a prospectively collected database of ePROs from oncology clinics administering Patient Care Monitor 2.0 (PCM), a validated symptom survey of 78 items for men and 86 for women. We tabulated the frequency of missing items by item and domain (emotional, functional and symptom-related), and examined these by age, gender, education, race and marital status. Results: In 20,986 encounters there were responses to at least 1 PCM item from 6,933 patients. On average just 1% of items were skipped per encounter. By domain, 12.3% of functional, 8.4% of symptom-related, and 1.6% of emotional constructs contained at least one missing item. The highest frequency of item non-response was seen in older patients (>60yo) and those with high school education or less. The most frequently skipped items included: “attend a paid job” (10.7%), “reduced sexual enjoyment” (3.8%), and “running” (3.7%). These questions may be less relevant to older individuals, who, for example, quit running years earlier or are retired. Men had less missingness overall, except for “cooks for self” and “house work”, which may reflect traditional gender roles in the Southeast US. Conclusions: In a real-world ePRO implementation, items pertaining to more universal issues for cancer patients, like emotional well-being, have much lower rates of missingness, especially compared to functional items like “attend a paid job.” These results suggest that patients differentially complete ePROs based on perceived question relevance to them. The underlying driver behind individual item non-response may itself be an important data point in clinical care, warranting further study and discussion during clinic visits.

Published: November 2019

Purpose

Session RPE (sRPE) is used to track internal training/competition load in athletes using a metric known as the acute to chronic workload ratio (ACWR). Research that reported on team sports has determined that if the acute load is higher than the chronic load, athletes are likely to sustain injury. No studies, however, have attempted to investigate internal load and injury in a tennis population despite the rigorous training loads. Therefore, the purpose of this study was to investigate if sRPE ACWR is associated with injury in junior tennis players over a 7-month time period.

Methods

Forty-two junior tennis players were recruited to participate, 26 were included in the final analysis. Players provided a rating of RPE as an estimate of training intensity every day after training/match sessions. sRPE, a measure of internal and external training load was calculated by multiplying the training/match sRPE by the session duration in minutes. Players self-reported all injuries. The ACWR was the primary independent variable. Acute load was determined as the total sRPE for 1 wk, whereas a 4-wk rolling average sRPE represented chronic load.

Results

Seventeen players sustained injuries. The model indicated that ACWR from the previous week (P < 0.001) and previous injury history (P = 0.003) were significant predictors of injury the following week. In the week preceding injury, the average ACWR was 1.57 (SD, 0.90).

Conclusion

Injured players had on average 1.5 times more training load in the past week compared with the previous 4 wk. A majority of players who went on to sustain an injury were not prepared for the load endured. These results were similar to previous studies investigating ACWR where an acute increase in load was associated with increased injury risk.

PAH ADSORPTION BY ACTIVATED CARBON. The growing population and the rapid economic development have led an increasing input of waste waters mainly from industries, agriculture and households into marine environment. In addition, discharge of maritime transportation and accidents of oil spills contribute to the marine as pollutants. The released compounds have dangerious effects, for example hazard to human health, hindrance to marine activities, and impairment of the quality of seawaters. Because of hydrophobic character, these compound contaminants tend to be adsorbed to sediment particles and therefore it could be considered as pollution reservoirs. They are also accumulated in the aquatic organisms and biomagnified in the food chains. Some contaminants pose a health risk to aquatic organisms and ultimately to humans who consume contaminated seafood. Therefore, study of activated carbon adsorption will reduce organic pollution such as PAH in marine environment.

The influence of training sampling size on the expected error rate in spatial classification
Authors: Dreižienė Lina , Karaliutė Marta
Published: November 2019

In this paper we use the pluged-in Bayes discriminant function (PBDF) for classification of spatial Gaussian data into one of two populations specified by different parametric mean models and common geometric anisotropic covariance function. The pluged-in Bayes discriminant function is constructed by using ML estimators of unknown mean and anisotropy ratio parameters. We focus on the asymptotic approximation of expected error rate (AER) and our aim is to investigate the effects of two different spatial sampling designs (based on increasing and fixed domain asymptotics) on AER.
Empirical Bayesian regression model for estimation of small rates
Authors: Jakimauskas Gintautas , Sakalauskas Leonidas
Published: November 2019

The efficiency of adding an auxiliary regression variable to the logit model in estimation of small probabilities in large populations is considered. Let us consider two models of distribution of unknown probabilities: the probabilities have gamma distribution (model (A)), or logits of the probabilities have Gaussian distribution (model (B)). In modification of model (B) we will use additional regression variable for Gaussian mean (model (BR)). We have selected real data from Database of Indicators of Statistics Lithuania – Working-age persons recognized as disabled for the first time by administrative territory, year 2010 (number of populations K = 60). Additionally, we have used average annual population data by administrative territory. The auxiliary regression variable was based on data – Number of hospital discharges by administrative territory, year 2010. We obtained initial parameters using simple iterative procedures for models (A), (B) and (BR). At the second stage we performed various tests using Monte-Carlo simulation (using models (A), (B) and (BR)). The main goal was to select an appropriate model and to propose some recommendations for using gamma and logit (with or without auxiliary regression variable) models for Bayesian estimation. The results show that a Monte Carlo simulation method enables us to determine which estimation model is preferable.
Distribution of the combinatorial multisets component vectors
Authors: Manstavičius Eugenijus , Petuchovas Robertas
Published: November 2019

We explore a class of random combinatorial structures called weighted multisets. Their components are taken from an initial set satisfying general boundedness conditions posed on the number of elements with a given weight. The component vector of a multiset of weight n taken with equal probability has dependent coordinates, nevertheless, up to r = o(n) of them as n→∞, we approximate by an appropriate vector comprised from independent negative binomial random variables. The main result is an estimate of the total variation distance.
Security analysis of key agreement protocol based on matrix power function
Authors: Vitkus Paulius , Sakalauskas Eligijus
Published: November 2019

Key agreement protocol (KAP) using Burau braid groups representation and matrix power function (MPF) is analyzed. MPF arguments are Burau representation matrices defined over finite field or ring. It is shown that KAP security relies on the solution of matrix multivariate quadratic system of equations over the ring with additional commutation constraints for matrices to be found. We are making a conjecture that proposed KAP is a candidate one-way function since its inversion is related with the solution of known multivariate quadratic problem which is NP-complete over any field. The one of advantages of proposed KAP is its possible effective realization even in restricted computational environments by avoiding arithmetic operations with big integers.

Method of marks for propositional linear temporal logic
Authors: Pliuškevičius Regimantas
Published: November 2019

It is known that traditional techniques used to ensure termination of a decision procedure in non-classical logics are based on loop-checking, in general. Nowadays, effective loop-check techniques based on histories are used instead of unrestricted loop-check. These techniques are widely and successfully applied also for non-classical logics containing induction-like axioms. These induction-like axioms create new type loops (“good loops”) along with ordinary “bad loops”. In this paper, some loop-check free saturation-like decision procedure based on some technique of marks is proposed. This saturation procedure terminates when special type marked sequents are obtained. This procedure is demonstrated for propositional linear temporal logic (PLTL) with temporal operators “next” and “always”.

Published: November 2019

When using Spatial Correlation Rule with Distance (SCRD) the selection of the neighborhood scheme influences classification accuracy. Spatial dependency in different situations remains at various distances, so, according to this, in applications it is important to choose a suitable neighborhood scheme. In the earlier papers of the authors, the nearest neighbor scheme was used. In this paper, several different neighborhood schemes are examined by large experiment.
Fast Fourier transform revisited
Authors: Pupeikis Rimantas
Published: November 2019

Using FFT (fast Fourier transform), it is assumed, that some signal samples in a respective period N are updated by a sensor in real time. It is urgent for every new signal sample to have new frequency samples (f.s.). The idea is that FFT should not be recalculated with every new signal sample, it is needed just to modify it, when the new sample replaces the old one.
Nonlinear thermal conductivity in gases
Authors: Janavičius Arvydas Juozapas , Turskienė Sigita
Published: November 2019

The nonlinear diffusion equation corresponds to the diffusion processes which can occur with a finite velocity. A.J. Janavičius proposed nonlinear equation which describes more exactly the diffusion of impurities in Si crystals in many interesting practical applications. The heat transfer in gases is also based on diffusion of gas molecules from hot regions to the coldest ones with a finite velocity by random Brownian motions. In this case the heat transfer can be considered using similar nonlinear thermal diffusivity equation. The approximate analytical solution of this nonlinear equation can be used for the experimental analysis of thermal conductivity coefficients using temperature profiles dependence on different temperatures and pressures in gases.

Published: November 2019

In this paper, effective utilization of processors in computer cluster is investigated. Generally, a computer cluster is treated as a specially designed system only for solving specific computationally intensive and time consuming problems. Commonly, computers in offices and universities are idle for a considerable proportion of the time. Therefore, in this research, we focus on exploitation of such computational resources. The experimental investigationshows that when executing multiple processes in each CPU core allows to solve computationally intensive problems more precisely compared to the case, where the number of processes is equal to the number of CPU cores, meanwhile the same amount of energy is consumed in both cases.

Objective: The purpose of this study was to evaluate the influence of the pH levels of three in-office bleaching gels on the surface roughness of bovine enamel, after the bleaching protocol. Materials and methods: 36 samples of bovine enamel were obtained, which were cut and divided into three groups (n=12): 40%hydrogen peroxide (Opalescence Boost40%), 35% hydrogen peroxide (Whiteness HP AutoMixx) and 35% hydrogen peroxide (Whiteness HP Blue), receiving a 40-minute application of bleaching. The average pH values were determined using a pH meter during the initial and final application of the gel. A roughness meter was used to assess surface roughness (Ra) before and after bleaching. Data were analyzed with the Friedmann and wilcoxon test (difference between groups); the Kruskall Wallis and U Mann test (difference in each group), as well as Pearson or Spearman test for correlation. Results: There is an increase in pH values from the beginning to the end of bleaching in all groups, except for the 35% hydrogen peroxide group (Whiteness HP Automixx). For surface roughness results there is an increase in all groups. No correlation was found between pH values of the bleaching gels and the surface roughness of the enamel after bleaching. Conclusions: Hydrogen peroxide bleaching gels with high concentrations that have a high or low pH could cause alterations in the surface of the tooth enamel, such as increase in surface roughness.

Authors: Michels Everton , Forcellini Fernando Antonio , Fumagali Alissa Emanueli Cabrera
Published: November 2019

There is a gap in the literature regarding the opportunities and barriers in using Toyota Kata routines, which clarify some obscure aspects of Toyota. Thus, the objective of this article is to identify, through a theoretical, mixed, descriptive and bibliographical research, carried out through a systematic literature review, the opportunities and barriers found in the use of these routines. As these aspects are very specific, our results suggest that the main barriers encountered in various contexts are: 1 - lack of direction and environmental preparedness (awareness), 2 - lack of value stream map, and 3 - lack of meetings Coaching Kata In addition, the main opportunities were: 1 - short cycles, 2 - knowledge sharing, and 3 - adaptability. Thus, it can be concluded that these opportunities and barriers not only in manufacturing make Toyota Kata deployment less natural, but can be solved with simple actions, so future deployments do not go through the same problems as well, future works can empirically prove whether or not they are recurrent.

ÖZET

Amaç: Bu
çalışmanın amacı; infertil ve fertil kadınların sosyokültürel ve ekonomik
durumlarını karşılaştırmak, bu etkilerin infertilite etyolojisindeki yerini
belirlemektir.

Gereç ve Yöntem: Bozok Üniversitesi Tıp
Fakültesi Hastanesi jinekoloji polikliniğine başvuran 64 infertil ve 65
infertil olmayan toplam 129 kadına anket uygulanmıştır. Bu anket yaş, meslek,
eğitim ve gelir düzey yanında aile tipi, ilişki sıklığı, infertilite süresi,
ovulasyon zamanı farkındalığı ve stres düzeyini sorgulayan 16 sorudan
oluşmaktadır.

Bulgular: İnfertil kadınların yaş ortalaması 27.8±5.2, kontrol grubunun
32.0±5.1’idi ve gruplar arasında istatistiksel olarak anlamlı farklılık vardı
(p<0.001). İnfertil kadınların ortalama evlilik süresi kontrol grubuna göre
anlamlı olarak daha düşük saptandı (p<0.001). İnfertil kadınların
infertilite süresi ortalama 3.2±2.7 yıl olarak
bulundu. Aile tipi değerlendirildiğinde infertil grupta kontrol grubuna göre
anlamlı olarak daha fazla oranda geniş aile yapısı mevuttu (p=0.021). Katılımcıların
ovülasyon zamanı farkındalığı infertil grupta istatistiksel olarak anlamlı
oranda daha yüksek saptandı (p=0.002).

Sonuç: Çalışmamızda özellikle yaşam tarzı geniş aile yapısında olanlarda,
eğitim düzeyi ve gelir düzeyi düşük olanlarda infertilitenin daha fazla
görüldüğü tespit edilmiştir. Bu nedenle, yaşam tarzında yapılacak bazı
değişiklikler, eğitim düzeyinin ve gelir düzeyinin artışı infertilite
sıklığında azalmaya neden olabilir.

Çalışmanın primer sonuç değişkeni CDO’ dır.  Bulgular: Toplam 241 VET siklusundaki P kullanımı öncesi E kullanım süresi: 8 gün (%3), 9 gün (%8), 10 gün (%16), 11 gün (%16.5), 12 gün (%22.5), 13 gün (%20.5), 14 gün (%13.5) şeklinde dağılım göstermektedir. Östradiyol takviyesinin 12 günün altında kullanımının 12 gün üzerinde kullanımına kıyasla CDO üzerine anlamlı etkisi yoktur (OR=1.25; %95 CI [0.75-2.1], p=0.38). Klinik gebelik, erken ve fetal kayıp oranları da gruplar arasında benzerdir. Ortalama endometrial kalınlık gruplar arasında benzerdir (9.5mm). Östradiyol takviyesinin reprodüktif sonuçlarla ilişkisi her gün için ayrı ayrı değerlendirildiğinde de anlamlı bir fark saptanmamıştır Sonuç: Vitrifiye embriyo transfer sikluslarında genel kabul görenden daha kısa östradiyol kullanımı canlı doğum oranlarını etkilememekte, abort riskini artırmamaktadır. Bu durum test edilmemiş ancak kuvvetle kabül görmüş bu protokolü sorgulanır kılmaktadır
