Association between endometriosis and sexual satisfaction among a sample of lebanese women.

BACKGROUND: Endometriosis is a complex disease that affects approximately 10% of women of childbearing age. It is characterized by the presence of endometrial-like tissue outside the uterus and often results in symptoms such as pelvic pain and infertility. This condition may disturb mental health and decrease both the mental and physical health related quality of life of women. The aim of this study was to assess the emotional state and the intimate relational aspect of life in Lebanese women living with endometriosis. METHODS: This is a case-control study that included 317 women (65 participants with endometriosis and 252 controls (1:3 ratio)). Participants completed an online survey that included questions related to endometriosis, Sexual Satisfaction Scale for Women, Couple Satisfaction Index, Perceived Partner Responsiveness Scale and the Depression, Anxiety and Stress Scale. RESULTS: A significantly higher mean sexual satisfaction score was found in women without endometriosis compared to those with endometriosis (90.83 vs. 83.42; p = 0.006). No significant difference was found in terms of couple satisfaction, depression, anxiety, stress, and perceived partner responsiveness between the two groups. Higher couple satisfaction (Beta = 1.30) and perceived partner responsiveness (Beta = 0.16) were significantly associated with higher sexual satisfaction, whereas higher depression (Beta=-1.70) and having endometriosis compared to not (Beta=-6.51) were significantly associated with lower sexual satisfaction. CONCLUSION: This study validated the link between endometriosis and sexual satisfaction and invalidated the association between endometriosis and emotional state, as well as couple satisfaction and perceived partner responsiveness. Greater sexual satisfaction was, however, linked to greater perceived partner responsiveness and greater couple satisfaction, as well as decreased signs of depression, anxiety, and stress. More research is warranted to better understand how Lebanese women are coping with the disease and how clinicians may help them further.

Systematic review shows the benefits of involving the fathers of preterm infants in early interventions in neonatal intensive care units.

AIM: This review identifies interventions involving the fathers of preterm infants that have been tested in neonatal intensive care units (NICU). It examines their effects on the fathers and infants and highlights any differences between fathers and mothers who took part in the same interventions. METHODS: A systematic search was performed in English from 1995 to 1 September 2020, using the CINAHL, Cochrane Central Register of Controlled Trials, Embase, PubMed and PsycINFO databases. We examined 14 peer-reviewed studies that investigated NICU interventions involving 478 fathers, whose 511 infants were born before 37 weeks of gestation. These included empirical studies with clinical outcomes. RESULTS: Studies on fathers' interventions in NICUs were limited and mainly restricted to basic skin-to-skin contact or tactile interventions. The interventions had similar general positive effects on mothers and fathers when it came to infant physiological and behavioural reactions. There was also evidence of a positive effect on the fathers, including their mental health. CONCLUSION: Including fathers as active partners in the care of their preterm newborn infants produced good outcomes for both of them. Further research is needed to develop new, multimodal and interactive interventions that provide fathers with positive contact with their preterm infants.

Molecular Identification of Endophytic Bacteria in Leucojum aestivum In Vitro Culture, NMR-Based Metabolomics Study and LC-MS Analysis Leading to Potential Amaryllidaceae Alkaloid Production.

In this study, endophytic bacteria belonging to the Bacillus genus were isolated from in vitro bulblets of Leucojum aestivum and their ability to produce Amaryllidaceae alkaloids was studied. Proton Nuclear Magnetic Resonance (1H NMR)-based metabolomics combined with multivariate data analysis was chosen to compare the metabolism of this plant (in vivo bulbs, in vitro bulblets) with those of the endophytic bacteria community. Primary metabolites were quantified by quantitative 1H NMR (qNMR) method. The results showed that tyrosine, one precursor of the Amaryllidaceae alkaloid biosynthesis pathway, was higher in endophytic extract compared to plant extract. In total, 22 compounds were identified including five molecules common to plant and endophyte extracts (tyrosine, isoleucine, valine, fatty acids and tyramine). In addition, endophytic extracts were analyzed using Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) for the identification of compounds in very low concentrations. Five Amaryllidaceae alkaloids were detected in the extracts of endophytic bacteria. Lycorine, previously detected by 1H NMR, was confirmed with LC-MS analysis. Tazettine, pseudolycorine, acetylpseudolycorine, 1,2-dihydro-chlidanthine were also identified by LC-MS using the positive ionization mode or by GC-MS. In addition, 11 primary metabolites were identified in the endophytic extracts such as tyramine, which was obtained by decarboxylation of tyrosine. Thus, Bacillus sp. isolated from L. aestivum bulblets synthesized some primary and specialized metabolites in common with the L.aestivum plant. These endophytic bacteria are an interesting new approach for producing the Amaryllidaceae alkaloid such as lycorine.

Changes in the vocal qualities of mothers and fathers are related to preterm infant's behavioural states.

AIM: Little is known about infant-directed speech addressed to preterm infants. The current study investigated the association between changes in preterm infant behavioural states and acoustical qualities of both maternal and paternal infant-directed speech. METHODS: The mothers and fathers of 11 preterm infants participated in the study. Parents in turn were asked to talk freely to their infant over a 5-minute period. A total of 72 audio sequences were selected and analysed as a function of the behavioural states. RESULTS: Acoustic analysis showed that the vocal qualities of both fathers' and mothers' speech were influenced by infant behaviour. Parental infant-directed speech was characterised by higher loudness and spectral related parameters when preterm infants were sleeping, or transiting from one state to another, than when they were awake. Furthermore, loudness and spectral flux were higher in maternal speech than in paternal speech and fathers used higher pitch, jitter and shimmer when they saw their preterm infant in an awake state, demonstrating that alertness in infants modulates the father's voice. CONCLUSION: More research is needed to know whether other social partners' vocal qualities may also be related to infant behavioural state as such findings would have implications for clinical practice.

Exposure to human voices has beneficial effects on preterm infants in the neonatal intensive care unit.

We reviewed the literature up to March 2016 on the effects of nonmaternal voices on preterm infants' clinical outcomes. Of the 11 studies that met the inclusion criteria, 10 focused on short-term outcomes and one looked at long-term effects. The studies mainly showed that vocal stimuli increased preterm infants' stability in terms of heart rate, respiratory rate, oxygen saturation and behavioural measures. Improvements in feeding skills were also reported. The methods and the measures used in the studies were heterogeneous, making it difficult to draw reliable conclusions. CONCLUSION: Vocal stimuli increased preterm infants' stability, but further studies are needed.
