Remarks on Boston Consulting Group Method (BCG)

The situational plan of an enterprise in the market can be determined by means of the BCG method. The analysis consists in graphical presentation of the spatial distribution of the enterprise activity conditions. The presentation is made in two dimensional spaces in which horizontal axis represents the relative participation of the strategic units in the market and vertical axis represents the market growth rate. In such a coordinate system, enterprise activity can be visualized by means of the circles. In the paper a proposition has been put forward how to calculate the estimators of coordinates of circle centers and their radii in BCG method, taking into consideration the assessment errors on the axis of relative participation of the strategic unit under study in the market and on the axis of market’s growth rate. Advantage has been taken of the general case of LSE including Lagrange’s multipliers method with nonlinear constrains equations. An example illustrating the method proposed has been included.BGG method, estimator, situation plan, prognosing

Paternal Postpartum Bonding and Its Predictors in the Early Postpartum Period: Cross-Sectional Study in a Polish Cohort

Introduction: Parental postpartum bonding has been studied by many researchers focusing on maternal bonding. The objective of this study was to examine the psychological and socio-demographic predictors of paternal postpartum bonding in the early postpartum period. Methods: In this cross-sectional study, 131 couples (fathers median age of 32.37 years, SD = 4.59; mothers median age of 30.23 years, SD = 3.90) of newborns from full-term pregnancies were recruited from November 2019 until March 2020. The primary outcome was paternal postpartum bonding as measured by the Postpartum Bonding Questionnaire (PBQ). Secondary outcomes included: maternal and paternal anxiety [with the Generalized Anxiety Disorder (GAD) Assessment]; maternal and paternal stress [with the Parental Stress Scale (PSS)]; maternal depressive symptoms [with the Edinburgh Postpartum Depression Scale (EPDS)]; and maternal and paternal socio-demographic variables as fathers’ presence at childbirth, education level, age, and parental experience. Results: Paternal postpartum bonding was significantly correlated with paternal anxiety (moderate strength), maternal stress (strong correlation), and maternal postpartum bonding. No significant correlations between paternal postpartum bonding, maternal depression symptoms, and maternal anxiety were found. The mediating role of paternal stress in paternal postpartum bonding was proven. Paternal anxiety strengthens paternal stress (b = 0.98). Further, a high level of paternal stress disrupts paternal postpartum bonding (b = 0.41). Results of regression analyses have revelated that maternal infant bonding (p < 0.01) and paternal stress (p < 0.01) are the only predictors of parental postpartum bonding across all included variables. None of investigated socio-demographic variables were associated with paternal postpartum bonding. Conclusion: Notwithstanding limitations, the current findings add to a growing body of literature on paternal postpartum bonding. The results have shown that paternal mental health is related to parental postpartum bonding directly after delivery.publishedVersio

Development and validation of the attitude towards Surrogacy Scale in a polish sample

Surrogacy—is one of the most controversial methods of infertility treatment. This concept is associated with difficult ethical, psychological and social issues, in which each aspect may lead to different trends in attitudes. The study of attitudes in society plays an important role in the analysis of various aspects of a given phenomenon, helps to fill legal gaps and ambiguities, and to transform controversial dimensions into normative concepts. Thus, this study aimed to develop and validate a scale to assess the attitudes towards surrogacy. The survey used in this study, consisted of 24 questions, which were organized into the four subscales: general opinion on surrogacy and its social context (7 items), financing and legalizing surrogacy (8 items), the acceptance of surrogacy (4 items), and attitudes towards the intended parents and children born through surrogacy (5 items). 442 individuals participated in this study. The final version of Attitude towards Surrogacy Scale consists of 15 questions, grouped in three subscales: opinion on surrogacy ethical context, financing and legalizing surrogacy, and an acceptance of surrogacy. This is the first scale in Poland for the assessment of general attitudes towards surrogacy. This measure allows to capture the opinions towards three aspects of surrogacy: surrogacy’s ethical context, the financing and legalizing surrogacy, and acceptance of surrogacy. The scale can be addressed to various groups in the society, not only for studies related to reproductive medicine.publishedVersio

Defining Attachment and Bonding: Overlaps, Differences and Implications for Music Therapy Clinical Practice and Research in the Neonatal Intensive Care Unit (NICU)

Preterm birth and the subsequent hospitalization in the Neonatal Intensive Care Unit (NICU) is a challenging life event for parents and babies. Stress, anxiety, and depressive symptoms, limitations in holding or touching the baby, and medical complications during the NICU stay can negatively affect parental mental health. This can threaten the developing parent-infant relationship and might adversely impact child development. Music therapy in the NICU is an internationally growing field of clinical practice and research and is increasingly applied to promote relationship building between parents and babies. The two most commonly used concepts describing the early parent-infant relationship are ‘attachment’ and ‘bonding’. While frequently used interchangeably in the literature, they are actually not the same and describe distinctive processes of the early relationship formation. Thus, it is important to discuss the overlaps and differences between attachment and bonding and the implications for music therapy clinical practice and research. Whereas providing examples and possible scenarios for music therapists working on either bonding or attachment, the distinction between both concepts is relevant for many health care professionals concerned with early parenting interventions in the NICU. This will hopefully lead to a more precise use of theory, and ultimately, to a more informed clinical practice and research.publishedVersio

The effect of paternal anxiety on mother-infant bonding in neonatal intensive care

Background The hospitalization of a preterm infant in the NICU can lead to mental health difficulties in parents, but not much is known how paternal anxiety might affect the mother-infant relationship. Methods This prospective cohort study is a secondary analysis investigating how paternal anxiety levels might affect maternal bonding in the NICU using the dataset of the multinational pragmatic randomized controlled trial LongSTEP. A linear mixed-effects model was used for correlations of paternal anxiety (GAD-7) and maternal bonding (PBQ) at NICU discharge, and at 6 and 12 months infant corrected age. Secondary analyses examined effects on paternal anxiety related to: site (Argentina, Colombia, Israel, Norway, and Poland), maternal depression (EPDS), infant gestational age at birth, paternal age, and type of pregnancy. Results Paternal anxiety did not predict maternal bonding at NICU discharge (p = 0.096), at 6 months (p = 0.316), or at 12 months infant corrected age (p = 0.473). Secondary outcomes showed a statistically significant site effect, with higher paternal anxiety levels at the two Colombian sites at baseline (p = 0.014 and p = 0.020) and for one site at discharge (p = 0.012), but not for paternal age (p = 0.925 and p = 0.793), infant gestational age at birth (p = 0.974 and p = 0.686 and p = 0.340), or type of pregnancy (p = 0.381). Maternal depression predicted paternal anxiety at baseline (p < 0.001) and at discharge (p = 0.003). Conclusions In this study, paternal anxiety did not predict maternal bonding. Paternal anxiety varied by site, indicating a need for research on potential cultural differences in manifestation of paternal anxiety. Maternal depression predicted paternal anxiety, confirming a previously reported correlation. Further research on variations in paternal mental health in the neonatal period is warranted, as well as exploration of the social contagion of mental health in preterm parents.publishedVersio

The impact of cognitive impairment of individuals with Parkinson's disease on their caregivers' mental health: A systematic review protocol

Introduction Parkinson’s disease is a motor disease, the second most common neurodegenerative disorder with cardinal symptoms including bradykinesia, rigidity, and rest tremor accompanied by cognitive difficulties. The caregivers play a crucial role for individuals with Parkinson’s disease; however, many of them may suffer from high caregiver burden and mental health deterioration. This protocol of a systematic review presents a methodology of the review about the impact of cognitive impairment of individuals with Parkinson’s disease on their caregivers’ mental health. Material and methods Research will be identified by combining electronic databases searching and hand searching. The following databases will be included: Medline, PsycInfo, Web of Sciences, Cochrane, CINAHL, Embase and Scopus. The inclusion and exclusion criteria followed to PECOS model. The population of informal caregivers is defined as family members providing care on a patient with Parkinson’s disease. Exposure is linked with the evaluation of a cognitive functioning and outcome is defined as mental health among caregivers of individuals with Parkinson’s disease. We will include two types of studies: observational and intervention. Both, screening and eligibility will be done by two independent reviewers. Study quality will be assessed by two authors independently. Data will be extracted by two reviewers independently and will follow a pre-pilot extraction form. Any discrepancies will be resolved by discussion or/and consultation with another reviewer. The synthesis without meta-analysis (SWiM) guidelines will be used to report on included studies data. The metanalysis with usage the statistical software R version 4.1.2 (2021-11-01) “Bird Hippie” and R metaphor package 3.0–2 of will be conducted if possible. Discussion The goal of this systematic review is to present the association between caregivers’ mental health problems and their proteges’ cognitive impairment. It will enable to identify the gaps in literature and its methodology giving the suggestions for further research.publishedVersio

Attention deficit in children with attention deficit hyperactivity disorder at primary school age measured with the attention network test (ANT) : a protocol for a systematic review and meta-analysis

Background: Attentional deficits are among the most bothersome symptoms of attention deficit hyperactivity disorder (ADHD). To date, the neurological basis of attentional deficits has not been fully described according to the diagnostic criteria. ADHD may result from deficits in various attributes of attention. There is no specialist neuropsychological diagnostic method that allows reliable distinction between primary attention disorders in the etiology of ADHD and secondary problems that may arise due to co-morbidities. This protocol aims to systematically review the literature to evaluate patterns of attention common to school-age children either diagnosed with ADHD or at high risk of ADHD, as measured by the neuropsychological attention network test (ANT). Methods: Our search strategy will consist of electronic databases (PubMed, PsychInfo, Web of Science, EMBASE, and Cochrane Library) and hand searching. Both prospective cohort studies and prospective studies of intervention effects will be included, provided they used the ANT. The primary output variable will be attention deficits. Screening and eligibility will be done independently by two reviewers based on pre-specified eligibility criteria. Data extraction will be based on a pre-pilot data extraction form and conducted by two authors independently. The risk of bias will be assessed by two authors independently. The rating of the certainty of the entire body of evidence will be evaluated using the GRADE approach. Any discrepancies identified at any stage of the review will be resolved by discussion or/and consultation with another reviewer. We plan a narrative synthesis of findings and a quantitative meta-analysis if the data allow. Discussion: The research will identify patterns of neuropsychological ANT results characteristic of both school-age children diagnosed with ADHD and those at high risk of having ADHD. Our results could be used to check whether the pattern of a child’s performance in the ANT corresponds to the characteristic pattern of the results of children with ADHD. At present, the ANT is used only in research; the results of this review will serve as a useful benchmark. Hopefully, in the future, it will be possible to use the ANT in the wider diagnosis of ADHD

Developmental learning disorders in children with prenatal/perinatal exposure to hypoxia: A systematic review protocol

Background Developmental learning disorder (DLD) belongs to neurodevelopmental disorders because it results from the developmental neurodiversity of the brain. The main causes of DLD are genetics, but environmental factors, like inadequate supply of oxygen during pregnancy or labor, are considered. Methods Our search strategy will consist of electronic databases (PubMed, PsycINFO, Web of Science, EMBASE, and Cochrane Library) and hand searching. The observational studies including cohort and case-control studies will be included. The primary outcome will be (DLD). Screening and eligibility will be done independently by two reviewers based on pre-specified eligibility criteria. Data extraction will be based on a pre-pilot data extraction form, and conducted by two authors independently. Study quality will be assessed by two authors independently. Any discrepancies identified at any stage of the review will be resolved by discussion or/and consultation with another reviewer. We plan a narrative and tabular summary of the findings. Discussion This systematic review of aetiology follows the traditional approach to evidence-based healthcare. This secondary research will assess the association between hypoxia and DLD by assessing the relationship of health-related event and outcome and examining the association between them. This review can provide information for healthcare professionals and policymakers indicating whether taking into account information about hypoxia should be permanently included in the diagnostic ontogenetic interview in the process of diagnosing neurodevelopmental disorders.publishedVersio

Potential Psychological and Biological Mechanisms Underlying the Effectiveness of Neonatal Music Therapy during Kangaroo Mother Care for Preterm Infants and Their Parents

Neonatal music therapy (MT) has become more accessible worldwide. Previous research suggests multiple benefits of MT for preterm infants and their caregivers; however, far too little attention has been paid to understanding the mechanisms of change in previous Neonatal Intensive Care Unit (NICU)-MT research so far. This perspective article describes potential mechanisms of MT interventions exposed during kangaroo mother care on the preterm infant’s response (behavioral and physiological outcomes) and the mother-infant relationship. The paper focuses on the hypothalamic–pituitary–adrenal axis’ role in stabilization of behavioral state, the autonomic nervous system’s role in stabilization of physiologic state, as well as co-regulation as a potential mechanism for the developing of the parent-infant relationship. Mechanisms play a pivotal role in understanding variables related to the therapy course and well as in generating new knowledge regarding treatment susceptibility and optimizing resources. Understanding of the mechanisms of how interventions may lead to specific outcomes plays an important role in addressing the issue of improvement of currently available approaches of MT used in the NICUpublishedVersio

Associations of Maternal-Infant Bonding with Maternal Mental Health, Infant’s Characteristics and Socio-Demographical Variables in the Early Postpartum Period: A Cross-Sectional Study

(1) Background: There is a continuing discussion concerning the impact of preterm birth on Maternal-Infant bonding with inconsistent results. The large burden of preterm births calls for research to evaluate the impact of it on material psychological outcome in the early postpartum period. Thus, the aim of this study was to evaluate the relationship between maternal postpartum bonding with maternal mental health, socio-demographical factors, and child’s characteristics. (2) Methods: A cross-sectional study design was used. In total, 72 women (a mean age of 31.44 years old) of preterm infants (mean gestational age = 33.54; range 24–36) filled out socio-demographic questionnaires, Postpartum Bonding Questionnaire (PBQ), Edinburgh Postpartum Depression Scale (EPDS), Postpartum Depression Screening Scale (PDSS), Generalized Anxiety Disorder Assessment (GAD-7), and Parental Stress Scale (PSS) 1–3 days post-delivery; (3) Results: The results analyses have shown positive correlations between the overall result of maternal postpartum bonding with stress (p < 0.01), maternal educational level (p < 0.01), maternal age (p < 0.05) and the number of children (p < 0.01). However, there were no significant relationships between other investigated variables. The results of linear regression have revelated the important role of the overall scores in experience of stress among mothers (explaining 49% of the variability). The mediating role of maternal stress on maternal postpartum bonding was not found. That relationship of maternal postpartum bonding and maternal stress was not moderated through socio-demographic variables. (4) Conclusions: In this study mothers of prematurely born children had a good level of Maternal-Infant bonding. Maternal stress was found to be a predictor of maternal postpartum bonding among the tested variables. Surprisingly, the study results did not show significant relationships between maternal postpartum bonding and maternal mental health (depression and anxiety).publishedVersio
