- Background: Early detection of coronary atherosclerosis using coronary computed tomography angiography (CCTA), in addition to coronary artery calcification (CAC) scoring, may help inform prevention strategies. We used CCTA to determine the prevalence, severity, and characteristics of coronary atherosclerosis and its association with CAC scores in a general population.Methods: We recruited 30 154 randomly invited individuals age 50 to 64 years to SCAPIS (the Swedish Cardiopulmonary Bioimage Study). The study includes individuals without known coronary heart disease (ie, no previous myocardial infarctions or cardiac procedures) and with high-quality results from CCTA and CAC imaging performed using dedicated dual-source CT scanners. Noncontrast images were scored for CAC. CCTA images were visually read and scored for coronary atherosclerosis per segment (defined as no atherosclerosis, 1% to 49% stenosis, or ≥50% stenosis). External validity of prevalence estimates was evaluated using inverse probability for participation weighting and Swedish register data.Results: In total, 25 182 individuals without known coronary heart disease were included (50.6% women). Any CCTA-detected atherosclerosis was found in 42.1%; any significant stenosis (≥50%) in 5.2%; left main, proximal left anterior descending artery, or 3-vessel disease in 1.9%; and any noncalcified plaques in 8.3% of this population. Onset of atherosclerosis was delayed on average by 10 years in women. Atherosclerosis was more prevalent in older individuals and predominantly found in the proximal left anterior descending artery. Prevalence of CCTA-detected atherosclerosis increased with increasing CAC scores. Among those with a CAC score >400, all had atherosclerosis and 45.7% had significant stenosis. In those with 0 CAC, 5.5% had atherosclerosis and 0.4% had significant stenosis. In participants with 0 CAC and intermediate 10-year risk of atherosclerotic cardiovascular disease according to the pooled cohort equation, 9.2% had CCTA-verified atherosclerosis. Prevalence estimates had excellent external validity and changed marginally when adjusted to the age-matched Swedish background population.Conclusions: Using CCTA in a large, random sample of the general population without established disease, we showed that silent coronary atherosclerosis is common in this population. High CAC scores convey a significant probability of substantial stenosis, and 0 CAC does not exclude atherosclerosis, particularly in those at higher baseline risk.

Fatherhood as Taking the Child to Oneself : a Phenomenological Observation Study after Caesarean Birth

Tidskriftsartikel (refereegranskat)abstract
- This paper describes the meaning of a father’s presence with a full-term healthy child delivered by caesarean section, as observed during the routine post-operative separation of mother and child. Videotaped observations recorded at a maternity clinic located in the metropolitan area of Stockholm, Sweden formed the basis for the study, in which fifteen fathers with their infants participated within two hours of elective caesarean delivery in the 37th - 40th week of pregnancy. A phenomenological analysis based on Giorgi’s method was conducted on the data. The description of the new father’s experiences that emerged pointed to a process of being and becoming in taking the child to himself. Fatherhood developed gradually as a result of recurrent experiences of the child’s expressions. There was an ebb and flow between taking on the role of being a father and physical withdrawal from the role. The findings of this study not only confirm previous accounts of new fathers’ experiences, but go further in revealing an ebb and flow variation in the fathers’ involvement. What this indicates is that the process of transition to fatherhood requires not only presence but time. The period required for this process thus must not be disturbed, but supported, trusting in the father’s ability to assume his role as a father. It is suggested that, in addition to their relevance in guiding the attitudes and expectations of those professionally involved in postnatal care and community health, these findings could be useful in antenatal courses for parents, and especially in instances when caesarean birth is planned, to highlight the meaning of the role of fathers as caregivers

- The aim was to describe the meaning of the father’s lived experiences when taking care of his infant as the primary caregiver during the first hours after birth, when the infant was apart from the mother due to the mother’s postoperative care. Fifteen fathers were interviewed between 8 days to 6 weeks after birth. The results describe a movement towards father-child togetherness characterized by an immediate and gradual change within the father as he undertakes increasing responsibility while getting to know his child. The results can be reflected upon in antenatal classes in order to integrate the father’s important role in the care of his infant, in a situation where the mother-infant dyad has been interrupted.

- BACKGROUND: Previous reports have shown that skin-to-skin care immediately after vaginal birth is the optimal form of care for full-term, healthy infants. Even in cases when the mother is awake and using spinal analgesia, early skin-to-skin contact between her and her newborn directly after cesarean birth might be limited for practical and medical safety reasons. The aim of the present study was to compare the effects of skin-to-skin contact on crying and prefeeding behavior in healthy, full-term infants born by elective cesarean birth and cared for skin-to-skin with their fathers versus conventional care in a cot during the first 2 hours after birth. METHODS: Twenty-nine father-infant pairs participated in a randomized controlled trial, in which infants were randomized to be either skin-to-skin with their father or next to the father in a cot. Data were collected both by tape-recording crying time for the infants and by naturalistic observations of the infants' behavioral response, scored every 15 minutes based on the scoring criteria described in the Neonatal Behavioral Assessment Scale (NBAS). RESULTS: The primary finding was the positive impact the fathers' skin-to-skin contact had on the infants' crying behavior. The analysis of the tape recordings of infant crying demonstrated that infants in the skin-to-skin group cried less than the infants in the cot group (p<0.001). The crying of infants in the skin-to-skin group decreased within 15 minutes of being placed skin-to-skin with the father. Analysis of the NBAS-based observation data showed that being cared for on the father's chest skin-to-skin also had an impact on infant wakefulness. These infants became drowsy within 60 minutes after birth, whereas infants cared for in a cot reached the same stage after 110 minutes. Rooting activity was more frequent in the cot group than in the skin-to-skin group (p<0.01), as were sucking activities (p<=0.001) and overall duration of wakefulness (p<0.01). CONCLUSIONS: The infants in the skin-to-skin group were comforted, that is, they stopped crying, became calmer, and reached a drowsy state earlier than the infants in the cot group. The father can facilitate the development of the infant's prefeeding behavior in this important period of the newborn infant's life and should thus be regarded as the primary caregiver for the infant during the separation of mother and baby.

- IntroductionApixaban is an oral direct factorXa inhibitor developed for the prophylaxis and treatment of thromboembolic disorders. Laboratory monitoring is not necessary, but the effects on common coagulation reagents and assays constitute clinically valuable information. ObjectivesTo investigate the effects of apixaban on commonly used coagulation methods, and to evaluate anti-FXa assays for specific determination of the drug concentration. Materials and MethodsApixaban was added to plasma from healthy subjects in the concentration range 0-1000gL(-1), and analyses were performed with different reagents for activated partial thromboplastin time (APTT), prothrombin time (PT), antithrombin, proteinC, and proteinS. A lupus anticoagulant assay and an APTT assay with varying phospholipid concentrations were used to study the phospholipid dependence. ResultsIn general, apixaban showed fewer effects invitro than have been shown for rivaroxaban, another direct FXa inhibitor. The concentration needed to double the APTT varied between 2200 and 4700gL(-1), and the concentration needed to double the PT varied between 700 and 3900gL(-1). The effects on antithrombin, proteinC and proteinS assays were dependent on the type of reagent. Apixaban did not cause false-positive lupus anticoagulant results. Chromogenic anti-FXa assays showed linear dose-response curves with apixaban. ConclusionsTherapeutic concentrations of apixaban variably affect different assay groups, and even different reagents within an assay group. The effects were much smaller than with rivaroxaban. The use of APTT and/or PT assays to screen the anticoagulant activity of apixaban cannot be recommended. A chromogenic anti-FXa assay can be used for reliable measurements of apixaban concentration.
