Individual and community-level impact of infertility-related stigma in Malawi.

Infertility, a common experience among women and men worldwide, remains on the margins of public health and medicine in low-resource settings. Previous studies identified associations between individual experiences of infertility and negative outcomes, particularly in contexts where childbearing is imperative, but few have examined broader implications of infertility and infertility-related stigma on communities. To understand the production and impact of infertility-related stigma, this study analyzes 12 focus group discussions (FGDs) conducted with 104 women and men in rural Malawi.

Cross-Cultural Examination of Links between Parent-Adolescent Communication and Adolescent Psychological Problems in 12 Cultural Groups.

Internalizing and externalizing problems increase during adolescence. However, these problems may be mitigated by adequate parenting, including effective parent-adolescent communication. The ways in which parent-driven (i.

Extraoral anatomy in CBCT – a literature review. Part 3: Retromaxillary region.

In this review about extraoral anatomy as depicted by cone beam computed tomography, the retromaxillary region is discussed. A medium-sized (6 x 6 cm) or large (≥ 8 x 8 cm) field of view of the maxilla will inevitably depict the retromaxillary region that can be considered a «transition» zone between the viscerocranium and the neurocranium. Major structures of the region include the sphenoid bone and the pterygopalatine fossae.

Effects of Dimensions of Root-End Fillings and Peripheral Root Dentine on the Healing Outcome of Apical Surgery.

Objective: The objective of this study was to assess dimensions of root-end fillings (REFs), as well as peripheral root dentine (PRD) and their effects on the healing outcome of apical surgery.

Methods: Cone beam computed tomography (CBCT) scans were utilized to measure the REF length and width and the PRD thickness in 61 roots of 53 teeth 1 year after apical surgery. Measurements were taken in the mesio-distal as well as bucco-lingual directions.

Cone beam computed tomography artefacts around dental implants with different materials influencing the detection of peri-implant bone defects.

Objectives: To investigate the diagnostic accuracy of cone beam computed tomography (CBCT) for the diagnosis of peri-implant bone defects of titanium (Ti), zirconium dioxide (ZrO ) or titanium-zirconium (Ti-Zr) alloy implants.

Materials And Methods: Ti, Ti-Zr or ZrO implants with two diameters (3.3 mm, 4.

Mothers' parenting knowledge and its sources in five societies: Specificity in and across Argentina, Belgium, Italy, South Korea, and the United States.

In a cross-society comparison, we assessed the state of mothers' knowledge of child rearing and child development. The study included 1,077 mothers from five countries on four continents: Argentina, Belgium, Italy, South Korea, and the United States. A criteria-referenced instrument, the Knowledge of Infant Development Inventory, was used to assess parenting knowledge after being adapted for cross-society comparison using item response theory and the alignment optimization approach for testing between-sample measurement invariance.

Longitudinal associations between mothers' and fathers' anger/irritability expressiveness, harsh parenting, and adolescents' socioemotional functioning in nine countries.

The present study examines parents' self-efficacy about anger regulation and irritability as predictors of harsh parenting and adolescent children's irritability (i.e., mediators), which in turn were examined as predictors of adolescents' externalizing and internalizing problems.

A comparison of visual identification of dental radiographic and nonradiographic images using eye tracking technology.

Objectives: Eye tracking has been used in medical radiology to understand observers' gaze patterns during radiological diagnosis. This study examines the visual identification ability of junior hospital dental officers (JHDOs) and dental surgery assistants (DSAs) in radiographic and nonradiographic images using eye tracking technology and examines if there is a correlation.

Material And Methods: Nine JHDOs and nine DSAs examined six radiographic images and 16 nonradiographic images using eye tracking.

Assessing Mothers' Postpartum Depression From Their Infants' Cry Vocalizations.

Postpartum Depression (PPD), a condition that affects up to 15% of mothers in high-income countries, reduces attention to the needs of the child and is among the first causes of infanticide. PPD is usually identified using self-report measures and therefore it is possible that mothers are unwilling to report PPD because of a social desirability bias. Previous studies have highlighted the presence of significant differences in the acoustical properties of the vocalizations of infants of depressed and healthy mothers, suggesting that the mothers' behavior can induce changes in infants' vocalizations.

Unique air inclusions within the nasopalatine duct indicating its presence radiographically: a case presentation.

The anterior maxilla is characterized by the nasopalatine canal that originates bilaterally from the anterior nasal floor, subsequently fuses, and terminates at the incisive foramen in the anterior palate. Embryologically, this structure forms within the primary palate, and contains the neurovascular bundle, but also continuous epithelialized bands. The latter, termed nasopalatine ducts, usually degenerate and/or obliterate before birth.

Extraoral anatomy in CBCT – a literature review. Part 2: Zygomatico-orbital region.

This second article about extraoral anatomy as seen in cone beam computed tomography (CBCT) images presents a literature review of the zygomatico-orbital region. The latter bounds the maxillary sinus superiorly and laterally. Since pathologic changes of the maxillary sinus are a frequent indication for three-dimensional radiography, the contiguous orbital cavity and the zygomatic bone may become visible on CBCT scans.

Sinus floor elevation or referral for further diagnosis and therapy: A comparison of maxillary sinus assessment by ENT specialists and dentists using cone beam computed tomography.

Objectives: To compare ear, nose, and throat (ENT) specialists and dentists assessing health or pathology of maxillary sinuses using cone beam computed tomography (CBCT).

Material And Methods: Two ENT specialists and two oral surgeons assessed 100 CBCT datasets of healthy patients referred for dental implant placement in the posterior maxilla and decided on the possibility of sinus floor elevation or the necessity for further diagnostic examinations based solely on radiographic findings. Inter-rater agreements within the same specialty were calculated with Cohen's kappa and overall agreements with Fleiss kappa, and factors influencing the decisions taken were evaluated using regression analyses.

Nasopalatine canal and periapical radiolucency fusion following dentoalveolar trauma: A CBCT-based case-control study.

Background/aim: There is a lack of evidence regarding the radiological characteristics of a periapical radiolucency (PRL) fusion with the nasopalatine canal (NPC) following dentoalveolar trauma. The aim of this study was to assess the NPC enlargement resulting from fusion with a PRL and its relationship with the surrounding anatomical structures.

Material And Methods: A total of 100 patients was retrospectively recruited and divided into two groups: case group and control group.

Individual differences in executive function partially explain the socioeconomic gradient in middle-school academic achievement.

Children from families with low socioeconomic status (SES) earn lower grades, perform worse on achievement tests, and attain less education on average than their peers from higher-SES families. We evaluated neurocognitive mediators of SES disparities in achievement in a diverse sample of youth whose data were linked to administrative records of performance on school-administered tests of 7th grade reading and math proficiency (N = 203). We used structural equation modeling to evaluate whether associations between SES (measured at ages 8-9) and achievement (measured at age 13) are mediated by verbal ability and executive function (measured at age 10), a suite of top-down mental processes that facilitate control of thinking and behavior.

Intraosseous hemangiomas in the jaw area are rare pathological changes that occur in the mandible, particularly in the premolar and molar region. Clinically, a slowly increasing painless swelling is typical. Recurrent spontaneous bleeding and paresthesia may also occur.

Strangers, Friends, and Lovers Show Different Physiological Synchrony in Different Emotional States.

The mere copresence of another person synchronizes physiological signals, but no study has systematically investigated the effects of the type of emotional state and the type of relationship in eliciting dyadic physiological synchrony. In this study, we investigated the synchrony of pairs of strangers, companions, and romantic partners while watching a series of video clips designed to elicit different emotions. Maximal cross-correlation of heart rate variability (HRV) was used to quantify dyadic synchrony.

Examining effects of mother and father warmth and control on child externalizing and internalizing problems from age 8 to 13 in nine countries.

This study used data from 12 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, and United States; N = 1,315) to investigate bidirectional associations between parental warmth and control, and child externalizing and internalizing behaviors. In addition, the extent to which these associations held across mothers and fathers and across cultures with differing normative levels of parent warmth and control were examined. Mothers, fathers, and children completed measures when children were ages 8 to 13.

Effects of Baby Schema and Mere Exposure on Explicit and Implicit Face Processing.

In an increasingly multicultural society, the way people perceive individuals from the same vs different ethnic groups greatly affects their own and societal well-being. Two psychological effects that influence these perceptions are the Mere-Exposure Effect (MRE), wherein familiarity with certain objects or persons suffices for people to develop a preference for them, and the Baby Schema (BS), a set of specific facial features that evokes caregiving behaviors and an affective orientation in adults. In the present study, we aimed to investigate whether these two effects play a role in implicit physiological responses to babies vs.

External environment and internal state in relation to life-history behavioural profiles of adolescents in nine countries.

The external environment has traditionally been considered as the primary driver of animal life history (LH). Recent research suggests that animals' internal state is also involved, especially in forming LH behavioural phenotypes. The present study investigated how these two factors interact in formulating LH in humans.

Infant behaviors and maternal parenting practices: Short-term reliability assessments.

Consistency in the order of individuals in a group across short periods of time-reliability-is both important developmentally and meaningful psychologically. For example, documenting the reliabilities of infant behaviors and maternal parenting practices elucidates the nature and structure of early development. In this prospective short-term longitudinal study (Ns = 51 5-month infants and their mothers), we examined reliabilities of individual variation in multiple infant behaviors (physical development, social interaction, exploration, nondistress vocalization, and distress communication) and maternal parenting practices (nurturing, encouragement of motor growth, social exchange, didactic interaction, provision of the material environment, and speech to infant).

Examining the internalizing pathway to substance use frequency in 10 cultural groups.

Use of alcohol, tobacco, and drugs (i.e., substance use) is a leading cause of global health burden for 10-to-24-year-olds, according to the World Health Organization's index of number of years of life lost, leading international health organizations to prioritize the prevention of substance use before it escalates in adolescence.

Inaudible components of the human infant cry influence haemodynamic responses in the breast region of mothers.

Distress vocalizations are fundamental for survival, and both sonic and ultrasonic components of such vocalizations are preserved phylogenetically among many mammals. On this basis, we hypothesized that ultrasonic inaudible components of the acoustic signal might play a heretofore hidden role in humans as well. By investigating the human distress vocalization (infant cry), here we show that, similar to other species, the human infant cry contains ultrasonic components that modulate haemodynamic responses in mothers, without the mother being consciously aware of those modulations.

Specific domains of early parenting, their heritability and differential association with adolescent behavioural and emotional disorders and academic achievement.

Variations in parenting across large populations have rarely been described. It also remains unclear which specific domains of parenting are important for which specific offspring developmental outcomes. This study describes different domains of early parenting behaviours and their genetic heritability, then determines the extent to which specific domains of parenting are associated with later offspring outcomes.

A decade of infant neuroimaging research: What have we learned and where are we going?

The past decade has seen the emergence of neuroimaging studies of infant populations. Incorporating imaging has resulted in invaluable insights about neurodevelopment at the start of life. However, little has been enquired of the experimental specifications and study characteristics of typical findings.

Children's Academic, Artistic, and Athletic Competencies: Successes Are in the Eye of the Beholder.

A significant challenge to fully understanding children's academic and other competencies is dependency of the determination on the method of study, including notably who makes the assessment. This study examined similarities and differences in child, mother, father, and teacher reports of children's competencies across multiple domains of math, reading, music, and sports from two separate perspectives of rater agreement, mean level and order association. Two hundred and sixty-seven European American families were recruited from the mid-Atlantic region of the United States, and children, mothers and fathers, and teachers completed a commonly used rating measure of children's competencies when the children were 10 years of age.
