RESUMO
The perinatal and postpartum period is of great significance for women due to physiological changes, shifts in circadian rhythms, social setting, and psychological well-being, all of which affect the quality and quantity of their sleep. A mixed-studies systematic review was undertaken to enhance our understanding of sleep disturbances and mood disorders in women in late pregnancy and the postpartum period, their connection with breastfeeding, and the assessment of interventions for sleep disturbance. Three electronic databases (PUBMED, EMBASE and Google Scholar) were searched for qualitative, observational, and mixed-method studies from the year 2016 to June 2023. Twenty-nine articles were included in the analysis. The results were synthesized into four overarching themes: (Ñ) the sleep quality of women in the perinatal period; (ii) the relationship between sleep and breastfeeding; (iii) the relationship between sleep quality and emotional disturbance in the perinatal period; (iv) sleep interventions in the researched group. The subjective nature of the perception of sleep disturbances, along with the absence of an objective measurement tool is clearly an inconvenience. It is advisable to include the assessment of maternal sleep hygiene and family sleep patterns during postpartum healthcare provider appointments to develop strategies not only for women's sleep quality but also for their mental well-being.
RESUMO
Sepsis is caused by an inadequate or dysregulated host response to infection. Enzymes causing cellular degradation are matrix metalloproteinases (MMPs). Lipopolysaccharide (LPS) is used in models of sepsis in laboratory settings The aim of the study was to measure MMP 2 and 12 concentrations in spleen and lungs in rats in which septic shock was induced by LPS. The experiment was carried out on 40 male Wistar rats (5 groups of 8): 0. controls 1. administered LPS 2. administered bestatin 3. LPS and bestatin 4.bestatin and after 6â¯hours LPS Animals were decapitated. Lungs and spleens were collected. Concentrations of MMP-2 and MMP-12 were determined using immunoenzymatic methods. Mean (±SD) MMP-2 in the controls was 43.57 ± 20.53â¯ng/ml in the lungs and 1.7 ± 0.72â¯ng/ml in the spleen; Group 1: 31.28 ± 13.13â¯ng/ml, 0.83 ± 0.8â¯ng/ml; Group 2: 44.24 ± 22.75â¯ng /ml, 1.01 ± 0.32â¯ng/ml; Group 3: 35.94 ± 15.13â¯ng/ml, 0.41 ± 0.03â¯ng/ml; Group 4:79.42 ± 44.70â¯ng/ml, 0.45 ± 0.15, respectively. Mean MMP-12 in controls was 19.79 ± 10.01â¯ng/ml in lungs and 41.13 ± 15.99â¯ng/ml in the spleen; Group 1:27.97 ± 15.1â¯ng/ml; 40.44 ± 11.2â¯ng/ml; Group 2: 37.93 ± 25.38â¯ng/ml 41.05 ± 18.08â¯ng/ml; Group 3: 40.59 ± 11.46â¯ng/ml, 35.16 ± 12.89â¯ng/ml; Group 4: 39.4 ± 17.83â¯ng/ml, 42.04 ± 12.35â¯ng/ml, respectively. CONCLUSIONS: 1. Bestatin reduces MMP 2 and 12 levels in spleen and lungs. 2. Treatment with bestatin minimizes the effect of LPS.
