The Effect of Socioeconomic Factors on Maternal Perinatal Depressive Symptoms and the Contribution of Group Prenatal Support as a Preventive Measure

Background: The European and Greek financial turmoil that began in 2007 has had adverse health consequences. Stillbirth, low birth weight, infant mortality, and maternal suicide have all increased. The purpose of this study was to evaluate whether socioeconomic factors contribute to postpartum blues, and whether psychoprophylaxis with group prenatal education and support may have a beneficial effect. Materials and Methods: The sample study comprised 414 pregnant women equally divided into psychoprophylaxis or standard care. There were six psychoprophylaxis sessions, with two each week lasting 2 hours each in groups of five people at the urban health center of Larissa, Greece. A questionnaire was used for data collection, including (1) closed-type questions about sociodemographic characteristics, and medical and obstetric history; (2) the Hamilton Depression Scale; (3) a Blues Questionnaire; (4) the Holmes and Rahe stressful life events scale; and (5) a scale of effects of the economic crisis. Differences between the two groups and within the groups at different time points were assessed by two-way repeated measures ANOVA tests. Results: Maternity blues scores, depression scores at all time points, life stress event score, and financial difficulty score were all significantly related to each other in both groups at all time points (p < 0.01). The correlation between financial difficulties and depression/maternity blues disappeared after delivery in the intervention group. Financial difficulties, depression, and psychoprophylaxis sessions emerged as independent prognostic factors of maternity blues score, the group variable being most significantly associated with maternal blues. Conclusion: Although financial status as well as depression continued to play a role, the deterrent contribution of psychoprophylaxis was the most important parameter in the final maternity blues prognostic model. The results of our study show a potential for prevention and suggest interesting hypotheses for future interventions.
Influence of microphysical processes on the potential vorticity development in a warm conveyor belt: a case‐study with the limited‐area model COSMO

The potential vorticity (PV) in warm conveyor belts (WCBs) is strongly influenced by the latent heating associated with the various microphysical processes occurring during the formation of clouds. The first‐order effect is that PV increases below the level of maximum diabatic heating and decreases above. Thus, the WCB reaches the upper troposphere with low PV values and has the potential to influence the large‐scale dynamics. In order to quantify the influence of different microphysical processes on the diabatic heating rates (DHRs) and associated PV development during the ascent, a Lagrangian analysis is used and applied to a regional model simulation of a selected WCB event. First, the individual DHRs caused by the various microphysical processes are calculated with the COSMO model. Then, the DHRs and the associated changes in PV are evaluated along the WCB trajectories. The relative role of the different microphysical processes is quantified for the latent heating and the diabatic PV modification, for which the gradient of the latent heating and the absolute vorticity are crucially important. It is shown that condensation of vapour and depositional growth of snow each contribute ∼10 K to the total latent heating. However, the diabatic PV modification due to condensation is stronger since it occurs close to the cold frontal low‐level maximum of the z‐component of the absolute vorticity, ηz, whereas a similar heating rate gradient caused by depositional growth of snow modifies the PV much less since it occurs in a region with much weaker ηz. This highlights the importance of ηz for determining the PV modification due to a certain diabatic heating rate. Furthermore, cooling processes like the evaporation of rain, also co‐occurring with high ηz near the surface cold front, have the potential to strongly modify the PV below the WCB.

Design of a High–Efficient IPT System for Battery Charging Under CP-CV Charging Scenarios

Maintaining high efficiency and controlling output voltage with variable load is challenging for inductive power transfer (IPT) based battery charging systems. In addition, choosing the proper charging scenarios simultaneously with the battery's equivalent load variation significantly improves the charging rate. This paper proposes a semi-active rectifier (SAR) battery charging system on the basis of a series-series resonant IPT system using constant-power (CP) and constant-voltage (CV) charging modes. A novel control approach based on the adaptive selection of the operating frequency of IPT and the conduction angle of the SAR is used to achieve high efficiency in CP-CV modes. The inverter and the SAR are both capable of soft switching. Furthermore, considering the same maximum power in CP and constant-current (CC) modes, the CP mode offers more charging rate with less destructive effects. The proposed control strategy has been simulated, and a prototype system is implemented to show the high-efficiency performance of the system during CP-CV modes.
Effect of Dietary Phosphate Deprivation on Red Blood Cell Parameters of Periparturient Dairy Cows

Simple Summary Postparturient hemoglobinuria is a rare but deadly disease of dairy cows. Cows are affected mainly in the period closely following calving. The main clinical sign—the passing of strongly discolored urine—is caused by the breakdown of red blood cells within the bloodstream. The condition is generally believed to be associated with a dietary phosphorus deficiency, but the precise etiology is unknown. We, therefore, designed two studies to explore the effect of phosphorus deprivation on red blood cell form and function. In the first study, we fed a ration low in phosphorus for four weeks before to four weeks after calving. In the second study, we restricted phosphorus only before calving. Feeding a diet low in phosphorus throughout the periparturient period (Study I), resulted in severe anemia and hemoglobinuria in a subset of cows after calving. In addition, a subclinical form of the disease was discovered. The results provide insight into, and increase awareness of, the occurrence of postparturient hemoglobinuria and the role of phosphorus. Abstract Postparturient hemoglobinuria is a sporadic disease characterized by intravascular hemolysis and hemoglobinuria in early lactating dairy cows. The condition has empirically been associated with phosphorus (P) deficiency or hypophosphatemia; however, the exact etiology remains obscure. This paper summarizes two controlled studies investigating the effect of P deprivation during the transition period. In Study I, 36 late pregnant dairy cows were randomly assigned to either a diet with low, or adequate, P content from four weeks before calving to four weeks after calving. In Study II, 30 late pregnant dairy cows were again assigned to either a diet with low, or adequate, P for the last four weeks before calving only. Pronounced hypophosphatemia developed during periods of restricted P supply. In early lactation, a subtle decline of the red blood cell count occurred independently of the dietary P supply. In Study I, anemia developed in 11 cows on deficient P supply, which was associated with hemoglobinuria in five cases. Neither erythrocyte total P content nor osmotic resistance of erythrocytes were altered by dietary P deprivation. Restricted dietary P supply, particularly in early lactation, may lead to postparturient hemoglobinuria, but more frequently causes clinically inapparent hemolysis and anemia in cows.
Pharmacological Treatment of Bipolar Depression: A Review of Observational Studies

The persistence of depressive morbidity is frequent in bipolar disorder, and the pharmacological management of this symptomatology often lacks effectiveness. This systematic review aimed to summarize the results of the naturalistic observational studies on the pharmacological treatment of bipolar depression published through April 2022. The certainty of evidence was evaluated according to the GRADE approach. In sum, 16 studies on anticonvulsants, 20 on atypical antipsychotics, 2 on lithium, 28 on antidepressants, and 9 on other compounds were found. Lamotrigine, quetiapine, aripiprazole, and ketamine were the most investigated compounds. Overall, the results support the recommendations regarding the effectiveness of lamotrigine and quetiapine. In contrast to the current recommendations, aripiprazole was shown to be effective and generally well tolerated. Additionally, SSRIs were shown to be effective, but, since they were associated with a possibly higher switch risk, they should be used as an adjunctive therapy to mood stabilizers. Lithium was only studied in two trials but was shown to be effective, although the serum concentrations levels were not associated with clinical response. Finally, ketamine showed divergent response rates with a low certainty of evidence and, so far, unclear long-term effects. Heterogeneity in diagnosis, sample sizes, study designs, reporting of bias, and side effects limited the possibility of a head-to-head comparison.
An inverse eigenvalue problem for an arbitrary, multiply connected, bounded domain in R 3 with impedance boundary conditions

The basic problem in this paper is that of determining the geometry of an arbitrary, multiply connected, bounded region in $R^3 $, together with the impedance boundary conditions, from a complete knowledge of the eigenvalues $\{ \lambda _j \}_{j = 1}^\infty $ for the negative Laplacian $ - \nabla ^2 = - \sum_{i = 1}^3 (\partial/\partial x^i )^2$ in the $(x^1 ,x^2 ,x^3 )$-space, using the asymptotic expansion of the spectral function $\Theta (t) = \sum\nolimits_{j = 1}^\infty \exp ( - t\lambda _j )$ for small positive t.

Dynamic contact angle of spreading droplets: Experiments and simulations

This paper presents results of an experimental investigation of a single drop impact onto a dry, partially wettable substrate and its numerical simulation. Particularly, the drop spreading diameter and the dynamic contact angle are measured at different time instants after impact. Two surfaces, wax (low wettability) and glass (high wettability), are used to study the effect of surface wettability (static contact angle) on the impact dynamics. It is shown that existing empirical models for the dynamic contact angle (e.g., Hoffman–Voinov–Tanner law) do not predict well the change of the dynamic contact angle, especially at high capillary numbers. In addition to the experimental investigations, the drop impact was studied numerically, focusing primarily on the contact angle treatment. The singularity in the neighborhood of the moving contact line is removed from the computational domain and replaced by a local force with some dependence on the instantaneous advancing/receding contact-line velocity. The predi.
Radial molecular abundances and gas cooling in starless cores

Aims. We aim to simulate radial profiles of molecular abundances and the gas temperature in cold and heavily shielded starless cores by combining chemical and radiative transfer models. Attention is also given to the time-evolution of both the molecular abundances and the gas temperature. Methods. A determination of the dust temperature in a modified Bonnor-Ebert sphere is used to calculate initial radial molecular abundance profiles. The abundances of selected cooling molecules corresponding to two different core ages are then extracted to determine the gas temperature at two time steps. The calculation is repeated in an iterative process yielding molecular abundances consistent with the gas temperature. Line emission profiles for selected substances are calculated using simulated abundance profiles. Results. The gas temperature is a function of time; the gas heats up as the core grows older because the cooling molecules are depleted onto grain surfaces. The change in gas temperature associated with depletion is of the order of 1 K. The contributions of the various cooling molecules to the total cooling power change with time, but the main cooling molecule at all times, in the range of environments studied here, is CO. Radial chemical abundance profiles are non-trivial: different species present varying degrees of depletion and in some cases inward-increasing abundances profiles, even at t > 10 5 years. Line emission simulations indicate that cores of different ages can present significantly different line emission profiles, depending on the tracer species considered. Conclusions. Chemical abundances and the associated line cooling power change as a function of time. Most chemical species are depleted onto grain surfaces at densities exceeding ∼10 5 cm −3 . Notable exceptions are NH3 and N2H + ; the latter is largely undepleted even at nH ∼ 10 6 cm −3 . On the other hand, chemical abundances are not significantly developed in regions of low gas density even at t ∼ 10 5 years, revealed by inward-increasing abundance gradients. Except in high-density regions where the gas-dust coupling is significant, the gas temperature can be significantly different from the dust temperature. This may have implications on core stability. Owing to the potentially large changes in line emission profiles induced by the evolving chemical abundance gradients, our models support the idea that observed line emission profiles can, to some extent, be used to constrain the ages of starless cores.
Calculation of the relativistic rise in electron-impact-excitation cross sections for highly charged ions

Exact relativistic plane-wave Born (RPWB) matrix elements of the M\o{}ller interaction are incorporated in the ``analytic Born subtraction technique'' and employed in the relativistic convergent close-coupling method. Application to the calculation of high-energy electron-impact-excitation cross sections of highly charged hydrogenlike ions demonstrates the ``Bethe rise,'' an effect that is manifest in Bethe's original 1932 work on relativistic high-energy, electron-impact excitation. The result represents an improvement over Bethe's relativistic high-energy theory developed in the 1930s in that (i) both target and projectile electrons are represented relativistically with Dirac spinor wave functions and (ii) the dipole approximation plus additional assumptions are not employed in the RPWB scattering amplitude of the M\o{}ller interaction.
Minimum Relative Entropy Inversion: Theory and Application to Recovering the Release History of a Groundwater Contaminant

In this paper we show that given prior information in terms of a lower and upper bound, a prior bias, and constraints in terms of measured data, minimum relative entropy (MRE) yields exact expressions for the posterior probability density function (pdf) and the expected value of the linear inverse problem. In addition, we are able to produce any desired confidence intervals. In numerical simulations, we use the MRE approach to recover the release and evolution histories of plume in a one-dimensional, constant known velocity and dispersivity system. For noise-free data, we find that the reconstructed plume evolution history is indistinguishable from the true history. An exact match to the observed data is evident. Two methods are chosen for dissociating signal from a noisy data set. The first uses a modification of MRE for uncertain data. The second method uses “presmoothing” by fast Fourier transforms and Butterworth filters to attempt to remove noise from the signal before the “noise-free” variant of MRE inversion is used. Both methods appear to work very well in recovering the true signal, and qualitatively appear superior to that of Skaggs and Kabala [1994]. We also solve for a degenerate case with a very high standard deviation in the noise. The recovered model indicates that the MRE inverse method did manage to recover the salient features of the source history. Once the plume source history has been developed, future behavior of a plume can then be cast in a probabilistic framework. For an example simulation, the MRE approach not only was able to resolve the source function from noisy data but also was able to correctly predict future behavior.
Phosphorylation of IGFBP-3 by Casein Kinase 2 Blocks Its Interaction with Hyaluronan, Enabling HA-CD44 Signaling Leading to Increased NSCLC Cell Survival and Cisplatin Resistance

Cisplatin is a platinum agent used in the treatment of non-small cell lung cancer (NSCLC). Much remains unknown regarding the basic operative mechanisms underlying cisplatin resistance in NSCLC. In this study, we found that phosphorylation of IGFBP-3 by CK2 (P-IGFBP-3) decreased its binding to hyaluronan (HA) but not to IGF-1 and rendered the protein less effective at reducing cell viability or increasing apoptosis than the non-phosphorylated protein with or without cisplatin in the human NSCLC cell lines, A549 and H1299. Our data suggest that blocking CD44 signaling augmented the effects of cisplatin and that IGFBP-3 was more effective at inhibiting HA-CD44 signaling than P-IGFBP-3. Blocking CK2 activity and HA-CD44 signaling increased cisplatin sensitivity and more effectively blocked the PI3K and AKT activities and the phospho/total NFκB ratio and led to increased p53 activation in A549 cells. Increased cell sensitivity to cisplatin was observed upon co-treatment with inhibitors targeted against PI3K, AKT, and NFκB while blocking p53 activity decreased A549 cell sensitivity to cisplatin. Our findings shed light on a novel mechanism employed by CK2 in phosphorylating IGFBP-3 and increasing cisplatin resistance in NSCLC. Blocking phosphorylation of IGFBP-3 by CK2 may be an effective strategy to increase NSCLC sensitivity to cisplatin.
Evaluating the factors influencing Alignment of IT and Business in a Cloud Computing Environment

Aligning IT with business strategically is the recent area of attention among researchers and practitioners because of its potential impact on organizational performance. Currently, large numbers of enterprises are migrating towards cloud computing as on-premise implementation of Information technology (IT) infrastructure is expensive. The purpose of this research is to examine the factors that influence the alignment of IT and business in cloud computing environment. Therefore, this study used the Strategic Alignment Maturity (SAM) model as a framework to validate the evolution of IT-business alignment in a cloud computing platform. A questionnaire-based survey method was employed for data collection. The respondents are IT and business executives of adopter firms in India. The structural equation modeling technique is used to statistically validate the model. From the results, it is found that all the constructs contribute significantly to business alignment with cloud computing except partnering and skill maturity. This study contributes to the research related to the application of SAM model in investigating the alignment of cloud computing with business. Software vendors and information technology consultants can utilize this study in assisting a client in the alignment of business with IT strategically in a cloud computing environment.
A RELLICH TYPE IDENTITY AND APPLICATIONS

arbitrary given u∈C2(Ω _ ), where Ω is a smooth bounded domain contained in RN. This intrinsic identity has played an important role in many contexts in the theory of partial differential equations. Some earlier applications were considered by Rellich himself, Payne and Weinberger [8] and Nehari [7]. In [9] Pohozaev rediscovered a modified version of RellichOs identity in the study of eigenvalue problems of the form
College Students’ Belonging and Loneliness in the Context of Remote Online Classes during the COVID-19 Pandemic

The COVID-19 pandemic has drastically affected how higher education operates, but relatively little is known about its effects on students enrolled in remote online classes. Across two data collection timepoints, we sought to examine college students’ experiences, focusing particularly on their sense of belonging/loneliness, their course formats, and their experiences in the pandemic. Though some findings differed between data collected in fall 2020 and in spring 2021, we generally found that students’ belonging/loneliness was linked with their class format, aspects of their virtual classes, social contact, and experiences in the pandemic. This research demonstrates the importance both of understanding students’ experiences in general and of continuing to study students’ experiences as we progress from one stage of the pandemic to the next.
Resolvent operators for integral equations in a Banach space

Conditions are given which ensure the existence of a resolvent operator for an integrodifferential equation in a Banach space. The resolvent operator is similar to an evolution operator for nonautonomous differential equations in a Banach space. As in the finite dimensional case, this operator is used to obtain a variation of parameters formula which can be used to obtain results concerning the asymptotic behaviour of solutions and weak solutions.
Can we identify the risk factors for SIRS/sepsis after percutaneous nephrolithotomy? A meta‑analysis and literature review

With the increase in percutaneous interventions such as percutaneous nephrolithotomy (PCNL) for renal lithiasis, infectious complications are becoming more frequent. The present study performed a systematic Medline and Embase databases search, using the following words: ‘PCNL’ [MeSH Terms] AND [‘sepsis’ (All Fields) OR ‘PCNL’ (All Fields)] AND [‘septic shock’ (All Fields)] AND [‘urosepsis’ (MeSH Terms) OR ‘Systemic inflammatory response syndrome (SIRS)’ (All Fields)]. Because of the technological advances in endourology, articles published between 2012 and 2022 were searched. Of the 1,403 results of the search, only 18 articles, representing 7,507 patients in which PCNL was performed, met the criteria to be included in the analysis. All authors applied antibiotic prophylaxis to all patients and, in some cases, the infection was treated preoperatively in those with positive urine cultures. According to the analysis of the present study, the operative time has been significantly longer in patients who developed SIRS/sepsis post-operatively (P=0.0001) with the highest heterogeneity (I2=91%) compared with other factors. Patients with a positive preoperative urine culture had a significantly higher risk of developing SIRS/sepsis following PCNL (P=0.00001), OD=2.92 (1.82, 4.68) and there was also a high degree of heterogeneity (I2=80%). Performing a multi-tract PCNL also increased the incidence of postoperative SIRS/sepsis (P=0.00001), OD=2.64 (1.78, 3.93) and the heterogeneity was a little smaller (I2=67%). Diabetes mellitus (P=0.004), OD=1.50 (1.14, 1.98), I2=27% and preoperative pyuria (P=0.002), OD=1.75 (1.23, 2.49), I2=20%, were other factors that significantly influenced postoperative evolution. A total of two factors analyzed, body mass index and patient's age, did not influence the outcome, P=0.45, I2=58% and P=0.98, I2=63%.
