Nightlily (Hemerocallis citrina Baroni) is an important vegetable with edible floral organs. It possesses considerable economic value due to its edibility, ornamental, and medicinal properties. However, the genetic linkage map construction and quantitative trait locus (QTL) mapping of nightlily have not been performed. This study used two varieties ‘Dongzhuanghuanghua’ and ‘Chonglihua’ of nightlily as cross parents to establish an intraspecific hybridization population of 120 F₁ progenies. The ‘Datonghuanghua’ (female) variety of nightlily and ‘Lullaby Baby’ (male) variety of daylily were selected to construct an interspecific hybridization population of 55 F₁ progenies. A total of 965 expressed sequence tag–simple sequence repeats (EST-SSRs), along with 20 SSR markers from various sources, were used for genetic mapping. Among these markers, CT/TC (9.24%) of the dinucleotide and GGA/GAG/AGG (4.67%) of the trinucleotide repeat motifs were most abundant. In the intraspecific hybridization genetic map, a total of 124 markers were resolved into 11 linkage groups, with a total map length of 1535.07 cM and an average interval of 12.38 cM. Similarly, the interspecific hybridization map contained 11 linkage groups but with 164 markers, a total map length of 2517.06 cM, and an average interval of 15.35 cM. The two constructed maps had 48 identical markers and demonstrated good collinearity. The collinearity analysis showed that 161 markers hit the genomic sequence of the published H. citrina genome, indicating that the two constructed genetic maps had high accuracy. Phenotypic data were investigated over two consecutive years (2018 and 2019) for flower bud fresh weight, dry weight, and bud length in two hybridization populations. A total of nine QTLs associated with flower bud-related traits were identified, among which those located on linkage group 8 of the intraspecific genetic map and linkage group 4 of the interspecific genetic map showed good stability. All nine QTLs had LOD values of not less than 4 and PVE values of not less than 15% over two years. This is the first report about the intra- and interspecific genetic map construction and QTL mapping of the flower bud-related traits in nightlily based on a genetic map. The results promote marker-assisted breeding and offer insights into the mechanisms underlying important traits of the genus Hemerocallis. Full article

This essay argues that one of the distinguishing characteristics of Chuck Palahniuk’s self-described “Horror Trilogy” of novels, Lullaby, Diary, and Haunted, is their representation of obsessions, compulsions, and obsessive–compulsive disorders. This essay analyses these representations from a variety of different perspectives, including medical and psychiatric approaches, clinical and self-help narratives, and biocultural readings emanating from cultural history and critical disability studies. It is demonstrated that the novels reflect a range of the debates that arise from these competing approaches, and the points of similarity and difference in the readings produced are identified. Palahniuk’s representations, it is suggested, must be seen in the contexts of a number of his recurrent thematic preoccupations, and of his engagement with existential comedy. Ultimately, this essay suggests that Palahniuk’s representations of obsessions, compulsions, and OCD must be seen as multi-faceted and protean, as befitting the awareness of the complicated current debates about their conceptualisation that the novels display.

Background: There is a knowledge-to-practice gap regarding parent-delivered pain management, and few studies have investigated parents’ and nurses’ participation in and acceptance of combined parent-delivered pain-alleviating interventions such as skin-to-skin contact (SSC), breastfeeding, and parental musical presence. This study investigated parents’ and nurses’ perceptions of and reflections on experiencing combined parent-delivered pain management. Methods: This qualitative study applies a collaborative participatory action research design using ethnographic data collection methods such as focus groups, video observations, and video-stimulated recall interviews with parents and nurses. Results: The results concern three main categories, i.e., preparation, participation, and closeness, as well as various sub-categories. Preparations were central to enabling combined parent-delivered pain management. Participation was facilitated by parental musical presence, in which parents shifted their attention toward their infant. Closeness and presence during neonatal care helped parents become active during their infant’s painful procedures. Parental lullaby singing created a calm and trusting atmosphere and after the procedure, both parents and nurses felt that they had successfully supported the infant through a potentially painful procedure. Conclusions: Mental and practical preparation is central to implementing combined parent-delivered pain management. When parents and nurses explored the interventions, they found the methods feasible, promoting self-efficacy and confidence in both parents and nurses. Full article

Background: Noise reduction in the Neonatal Intensive Care Unit (NICU) is important for neurodevelopment, but the impact of music therapy on noise is not yet known. Objective: To investigate the effect of music therapy (MT) on noise levels, and whether individual MT (IMT) or environmental MT (EMT) increases meaningful signal-to-noise ratios (SNR). Study design: This case-control study was conducted in a level III NICU. Noise levels were recorded simultaneously from two open bay rooms, with a maximum of 10 infants in each room: one with MT and the other without. MT sessions were carried out for approximately 45 min with either IMT or EMT, implemented according to the Rhythm Breath and Lullaby principles. Noise production data were recorded for 4 h on 26 occasions of EMT and IMT, and analyzed using R version 4.0.2 software. Results: Overall average equivalent continuous noise levels (Leq) were lower in the room with MT as compared to the room without MT (53.1 (3.6) vs. 61.4 (4.7) dBA, p = 0.02, d = 2.1 (CI, 0.82, 3.42). IMT was associated with lower overall Leq levels as compared to EMT (51.2 vs. 56.5 dBA, p = 0.04, d = 1.6 (CI, 0.53, 1.97). The lowest sound levels with MT occurred approximately 60 min after the MT started (46 ± 3.9 dBA), with a gradual increase during the remaining recording time, but still significantly lower compared to the room without MT. The SNR was higher (18.1 vs. 10.3 dBA, p = 0.01, d = 2.8 (CI, 1.3, 3.86)) in the room with MT than in the room without MT. Conclusion: Integrating MT modalities such as IMT and EMT in an open bay NICU room helps reduce noise. Both MT modalities resulted in higher SNR compared to the control room, which may indicate that they are meaningful for the neurodevelopment of preterm infants. Full article

The fetal environment provides the fetus with multiple potential sources of rhythmic stimulation that are not present in the NICU. Maternal breathing, heartbeats, walking, dancing, running, speaking, singing, etc., all bathe the fetus in an environment of varied rhythmic stimuli: vestibular, somatosensory, tactile, and auditory. In contrast, the NICU environment does not offer the same proportion of rhythmic stimulation. After analyzing the lack of rhythmic stimulation in the NICU, this review highlights the different proposals for vestibular and/or auditory rhythmic stimulation offered to preterm infants alone and with their parents. The focus is on the beneficial effects of auditory and vestibular stimulation involving both partners of the mother–infant dyad. A preliminary study on the influence of a skin-to-skin lullaby on the stability of maternal behavior and on the tonic emotional manifestations of the preterm infant is presented as an example. The review concludes with the importance of introducing rhythmic stimulations in the NICU. Full article

Prematurity deprives infants of the prenatal sensory stimulation essential to their correct development; in addition, the stressful environment of the NICU impacts negatively on their growth. The purpose of this review was to investigate the effects of NICU noise pollution on preterm infants and parents. We focused on the systems and projects used to control and modulate sounds, as well as on those special devices and innovative systems used to deliver maternal sounds and vibrations to this population. The results showed beneficial effects on the preterm infants in different areas such as physiological, autonomic, and neurobehavioral development. Although most of these studies highlight positive reactions, there is also a general acknowledgement of the current limits: small and heterogeneous groups, lack of structured variable measurements, systematic control groups, longitudinal studies, and normative values. The mother’s presence is always preferred, but the use of music therapy and the devices analyzed, although not able to replace her presence, aim to soften her absence through familiar and protective stimuli, which is a very powerful aid during the COVID-19 pandemic.

Guided by the hopeful possibilities of birth, breath and beginning that Hannah Arendt and Luce Irigaray variously articulate, this paper examines the lullaby as an expressive form that emerges (in a variety of contexts as distinct as medieval Christendom and contemporary art) as narrative between natality and mortality. With narrative understood as praxis according to Arendt’s schema, and articulated in what Irigaray might designate as an interval between two different sexuate subjects, the lullaby (and the voice that sings it) is found to be a telling of what it is to be human, and a hopeful reminder of our capacity both for self-affection and -preservation, and for meeting and nurturing others in their difference.
