General, Interpersonal, and Gender Role Specific Risk Factors of Postpartum Depressive Symptoms in Fathers
Authors: Fentz Hanne N⊘rr , Simonsen Marianne , Trillingsgaard Tea 
Published: August 2019

Introduction: Paternal postnatal depression has significant negative consequences for the family and child. Still, only little attention has been paid to potential unique risk factors of depression in fathers and the theoretical grounding of such research is sparse. Method: This study examined prenatal risk factors derived from three theoretical models: the cognitive vulnerability-stress model, the interpersonal model, and the gender role risk model of paternal postnatal depression. The sample consisted of 211 expectant fathers, of whom 5.7% scored above the clinical cut-off on the Edinburgh Postnatal Depression Scale, and 235 mothers were included as a reference group. Participants filled in questionnaires during pregnancy and four months postpartum. Results: The study results suggest that prenatal depressive score is the strongest risk factor for both paternal and maternal postnatal depressive symptoms. In addition, childhood separation from parents, unemployment, financial strain, and doubts about having the child were unique risk factors for paternal depressive symptoms, while lower marital satisfaction was a unique risk factor for maternal depression. Discussion: These findings highlight that beyond the strong role of prenatal depressive symptoms for both genders, specific risk factors for father depression exist. This may be informative to health care professionals in increasing the reach and prevention of depression in new fathers.
Are sports bettors looking at responsible gambling messages? An eye-tracking study on wagering advertisements
Authors: Lole Lisa , Li En , Russell Alex M. , Greer Nancy , Thorne Hannah , Hing Nerilee 
Published: August 2019

Background and aims
The broadcast of wagering advertisements during televised sports matches has been associated with various adverse outcomes. In order to counter these effects, legislative bodies require wagering operators to include responsible gambling messages in their advertisements; however, the effectiveness of these messages is unclear. This study sought to examine the extent to which responsible gambling messages are looked at, in the wider context of gambling advertisements.

Methods
Forty-nine regular sports bettors and 10 non-gamblers viewed a series of sports betting advertisements, while an eye-tracker recorded the number of fixations placed on responsible gambling messages, as well as other text-based wagering content.

Results
Responsible gambling messages were, generally, presented in a non-conspicuous manner. Eye-tracking data revealed that significantly fewer fixations were placed on responsible gambling messages, compared to wagering information (p < .001); however, this effect did not differ according to level of gambling risk (p = .169). The number of fixations placed on the different types of responsible gambling messages was found to vary, based on gambling risk (p = .006), as well as, what appears to be, the physical characteristics of these messages.

Discussion
Very few fixations were placed on, or near, responsible gambling messages, compared to other wagering information, meaning that, in their current form, they are unlikely to be effective in protecting against gambling harm. Preliminary evidence shows that presenting messages on a high-contrast/block-color background increases the number of fixations on these.

Conclusion
Further research is needed to identify ways of increasing the effectiveness of responsible gambling initiatives in the sports betting context.

Published: August 2019

The aim to evaluate medical appointments, as well as awareness, adherence and attitude of patients to medical treatment of obesity based on the results of a survey of patients with a prospective outpatient registry.Materials and methods. Total 305 patients with obesity in the outpatient “PROFILE” register were surveyed, including self-assessment questions regarding their own body weight, prescription of obesity treatment by doctors, patients’ adherence to the implementation of these recommendations, propensity to self-medication and information about personal financial costs for the treatment of this disease. 42 (12 %) patients refused to participate in the survey. 213 people (69.8 %) who answered the questionnaire were diagnosed with obesity of the 1st degree, 63 (20.7 %) – obesity of the 2nd degree; obesity grade 3 was detected in 29 people (9.5 %). Waist circumference in women averaged 104.7 ± 12.9 cm, in men – 116.7 ± 9.6 cm – all patients had abdominal obesity. 263 (86.2 %) people had arterial hypertension, 117 (38.4 %) patients had coronary heart disease; type 2 diabetes mellitus was diagnosed in every fourth patient (85 (27.2 %) people); atrial fibrillation was diagnosed in 55 (18 %) patients; 48 (15.7 %) people had a history of myocardial infarction, 23 (7.5 %) patients had a stroke.Results. According to the survey results, only one in four patients – 77 (25.2 %) – out of 305 patients who participated in the survey knew about the possibility of drug treatment of obesity. Mostly, patients received recommendations for non-drug treatment of obesity: 242 patients (79.3 %) were recommended to reduce caloric intake, 194 (63.6 %) – increased physical activity. Only 37 (12.1 %) patients with obesity were recommended for weight correction, significantly more often they were recommended and taken by patients with 2 and 3 degrees of obesity compared to patients with obesity of 1 degree (p <0.0001). At the time of the survey, none of the patients were taking drugs to treat obesity. Previous experience of drug weight loss had 42 (13.8 %) participants of the survey. Most patients (more than 70 %), in principle, are not ready to spend money on the fight against overweight, and drugs are considered an extra item of expenditure almost 90 % of obese patients. There is a significant relationship (p = 0.008) between the severity of the disease and patients’ spending on obesity treatment in the range of 1–5 thousand rubles per month: the higher the degree of obesity, the more patients agree to spend this amount on the treatment of the disease.Conclusion. According to the results of the survey, medical treatment of obesity is prescribed by doctors rarely. Apparently, this is due to the extremely low awareness of patients about the possibilities of drug therapy in the treatment of overweight and obesity, the popularity of biologically active additives independently used by patients to reduce weight.

Nar (Punica
granatum L.) günlük diyet içerisinde sıklıkla tüketilen bir meyve olup,
ayrıca nar ekşisi formunda da yemek ve salatalarda çeşni olarak sıklıkla
kullanılmaktadır. Bu çalışmada ise Hatay ve Şanlıurfa yörelerinde geleneksel
olarak üretilen iki farklı nar ekşisi örneğinin potansiyel antibakteriyel ve
antimutajenik etkisinin tespiti amaçlanmıştır. Antibakteriyel aktivite
analizi agar kuyu difüzyon metoduna göre yapılmış olup, test bakterisi olarak
Bacillus subtilis subsp. spizizenii ATCC 6633, Staphylococcus aureus ATCC 6538, Bacillus licheniformis ATCC 14580 ve Enterobacter aerogenes ATCC 13048 kullanılmıştır. Antimutajen
etki analizlerinde ise Ames Testi kullanılmış ve Salmonella Typhimurium TA 98 ve TA 100 suşları tercih edilmiştir.
Analiz sonuçlarına göre Hatay nar ekşisinin test bakterilerine karşı
18.09-25.63 mm inhibisyon zonu meydana getirdiği tespit edilirken, Şanlıurfa
nar ekşisinde bu değer 14.84-22.32 mm olarak gözlemlenmiştir. Ayrıca; Ames

Efficient Optimization of Well-Drilling Sequence with Learned Heuristics
Authors: Wang Lingya , Oliver Dean S. 
Published: August 2019

SummaryWhen preparing a field–development plan, the forecast value of the development can be sensitive to the order in which the wells are drilled. Determining the optimal drilling sequence generally requires many simulation runs. In this paper, we formulate the sequential decision problem of a drilling schedule as one of finding a path in a decision tree that is most likely to generate the highest net present value (NPV). A nonparametric online–learning methodology is developed to efficiently compute the sequence of drilling wells that is optimal or near optimal. The main ideas behind the approach are that heuristics from relaxed problems can be used to estimate the maximum value of complete drilling sequences constrained to previous wells, and that multiple online–learning techniques can be used to improve the accuracy of the estimated values. The performance of various heuristic methods is studied in a model for which uncertainty in properties is neglected. The initial heuristic used in this work generates a higher estimated NPV than the actual maximum NPV. Although such a heuristic is guaranteed to find the true optimal drilling order when used in the A* informed-search algorithm method, the cost of the search can be prohibitive unless the initial heuristic is highly accurate. For the variants of heuristic search methods with weighting parameters, the results show that it might not be possible to identify parameters that can be used to find a solution quickly without sacrificing the accuracy of the estimated NPV in this drilling–sequence problem. In contrast, the online learned heuristics derived from observations from previous drilling steps are shown to outperform the other variants of heuristic methods in terms of running time, accuracy of the estimated value, and solution quality. Multilearned heuristic search (MLHS) with space reduction (MLHS–SR) is an efficient and fast method to find a solution with high value. Continuing the search with space restoration is guaranteed to improve the solution quality or find the same solution as the MLHS without any space reduction.
Microfluidic Investigation of Low-Salinity Effects During Oil Recovery: A No-Clay and Time-Dependent Mechanism
Authors: Du Yujing , Xu Ke , Mejia Lucas , Zhu Peixi , Balhoff Matthew T. 
Published: August 2019

SummaryWe present a study of the low–salinity effect during oil recovery using microfluidics experiments in an attempt to narrow the gap between pore–scale observations and porous–media–flow mechanisms, and to explain one type of low–salinity effect with delayed oil recovery and without the presence of clay. A microfluidic toolbox is used, including single–pore–scale microchannels, a pore–network–scale (approximately 102 pores) micromodel, and a reservoir–on–a–chip model (approximately 104 pores with heterogeneity), all with 2D connectivity. Experiments at the single–pore scale reveal a time–dependent oil dewetting and swelling behavior when a crude–oil droplet is in contact with low–salinity water. An interplay between water chemical potential and oil–phase polar compounds explains this pore–scale observation well. Experiments at the pore–network scale illustrate that the dewetting and swelling of residual oil in the swept region increase the water–flow resistance, modifying the flow field and thus redirecting the flooding liquid into unswept regions. This pore–network–scale effect is re–expressed into a macroscale model as a sweep–efficiency improvement derived from the change of relative permeabilities, which requires time to develop. Finally, experiments on our “reservoir–on–a–chip” model show significant incremental oil recovery during tertiary low–salinity waterflooding and confirm that late–time sweep–efficiency improvement contributes to most of the incremental oil recovery. On the basis of this microfluidic framework, we emphasize the following three findings: Low–salinity tertiary waterflooding can improve oil recovery by an improvement of sweep efficiency, which is a consequence of residual–oil dewetting and swelling.The low–salinity effect can occur without the existence of clay.The wettability alteration and oil swelling are time–dependent processes and should be expressed as a function of oil/water contact time rather than dimensionless time [pore volume (PV)], which explains some observations from previous coreflood experiments.
