The Effect of Mother's Breastsleeping Behavior on Attachment and Postpartum Sleep Quality.

Background: Nowadays, the increasing importance of mother-infant contact, the significant impact of mother and baby's sleep quality, and the positive effects on breastfeeding are factors that make breastfeeding sleep important.

Aim: The aim of this study was to examine the effect of mothers' breastsleeping behavior on attachment and postpartum sleep quality.

Methods: This study is cross-sectional.

Anatomical variations of the superficial palmar arch in human fetuses.

The superficial palmar arch is an important anatomical structure that contributes to the arterial supply of the palmar side of the hand in the upper extremity. However, there is limited information on the embryological morphological structure of the superficial palmar arch in the literature. We studied the types of the superficial palmar arch and determined their variations by dissecting 80 upper extremities of 40 formalin-fixed human fetuses (19 males, 21 females) 18-37 weeks of age.

[Assessment of COVID-19 Risky Contact of Healthcare Workers in an University Hospital].

Healthcare workers are the group with the highest risk of COVID-19 transmission. The illness of healthcare workers poses a risk to patients admitted to the hospital, colleagues and households besides their own health. In this study, it was aimed to determine the risk assessment and the factors associated with risk status of an university hospital healthcare workers after risky COVID-19 contact.

The prevalence of headache disorders in children and adolescents in Mongolia: a nationwide schools-based study.

Background: The Global Campaign against Headache collects data from children (7-11 years) and adolescents (12-17 years) both to inform health and education policies and to contribute to the Global Burden of Disease (GBD) study. This survey in Mongolia was part of this global enquiry.

Methods: Following the generic protocol for the global enquiry, this was a schools-based cross-sectional survey.

Not all perceptual difficulties lower memory predictions: Testing the perceptual fluency hypothesis with rotated and inverted object images.

Studies typically show that perceptual difficulties at the time of encoding lower memory predictions. One potential exception to this is the inverted-word manipulation, in which participants produce equivalent memory predictions for upright and inverted words, despite higher free-recall performance for the inverted words (Sungkhasettee, Friedman, & Castel in Psychonomic Bulletin & Review, 18, 973-978, 2011). In the present set of experiments, we aimed to investigate the contributions of online perceptual difficulties versus a priori beliefs through two disfluency manipulations conceptually similar to the inverted-word manipulation: inversion and canonicity.

The assessment of serum lipid profiles of children with attention deficit hyperactivity disorder.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent psychiatric disorders in children and the pathophysiology remains obscure. Some studies show that lipid imbalances are associated with ADHD etiology. We studied the association of serum total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglyceride (TG) levels in ADHD.
