RESUMEN

The progressive desensitization of nurses in relation to fundamental needs (FNs) has been documented in anecdotical, scientific, and policy literature with nurses spending limited time at the bedside, thus affecting the quality of care and clinical outcomes. A potential reason that has been recognized is the limited nursing staff available in the units. However, other cultural, social, and psychological factors which have not been investigated to date may have a role in triggering the phenomenon. To investigate nurses' perceptions of the reasons that progressively detach clinical nurses from the FNs of patients, was the main intent of the study. In 2020, a qualitative study based on grounded theory following the Standards for Reporting Qualitative Research guidelines was performed. Purposeful sampling was adopted, by including 22 clinical nurses designated as 'good nurses' according to the perception of nurses working in executive and academic position. All agreed to be interviewed face-to-face. The detachment of nurses from the patients' FNs has been explained by three main factors that are interconnected: namely 'Being personally and professionally convinced regarding the role of FNs', 'Being progressively detached from the FNs', and 'Being forced to be detached from FNs'. Nurses also identified a category including strategies aimed at preventing detachment and 'Rediscovering the FNs as the core of nursing'. Nurses are personally and professionally convinced about the relevance of the FNs. However, they distance themselves from the FNs due to: (a) factors mainly attributable to internal personal and professional forces, such as the emotional fatigue that daily work entails; and (b) external forces related to the work environment where nurses work. To prevent this detrimental process that may result in negative outcomes for patients and their relatives, several strategies at the individual, organizational, and educational levels should be implemented.

RESUMEN

OBJECTIVE: To compare the efficacy of priming the uterine cervix before Manual Vaccum Aspiration (MVA) using 200 µg or 400 µg of vaginal misoprostol, inserted a mean time of 6 h before MVA in first trimester miscarriage. STUDY DESIGN: Randomized, triple-blind, non-inferiority clinical trial. Patients between 18 and 50 years old, with a diagnosis of miscarriage, were eligible for the study. Patients were allocated to receive either 200 µg or 400 µg of misoprostol before the MVA. The primary outcome was the need to dilate the uterine cervix with mechanical dilators (Hegar dilators). As a secondary outcome, cervical dilatation ≥8 mm before the procedure was considered successful. A difference of <25% was considered as non-inferior. RESULTS: Between December 21, 2016 and October 6, 2019, 269 women were screened. After screening, 105 and 106 women received 200 µg and 400 µg of misoprostol, respectively. Mechanical cervical dilatation was not necessary in 84.8% (95%CI 77% to 90%) and 96.2% (95%CI 91% to 99%), in the 200 µg and 400 µg groups, respectively [difference = 11.5% (95%CI 3.7% to 19.2%). Cervical dilatation of ≥8 mm was 52.4% (95%CI 42.9% to 61.7%) in the 200 µg misoprostol group, while in the 400 µg group was 71.7% (95%CI 62.5% to 79.4%) [difference = 19.3% (95%CI 6.5 to 32.2). CONCLUSION: After a mean time of 6 h, 200 µg of vaginal misoprostol is not inferior to 400 µg of misoprostol for cervical priming before MVA, in first trimester miscarriage. This non-inferiority was not observed when the ≥8 mm criterion was considered.

RESUMEN

Biomaterials can be applied in tissue engineering as scaffolds that resemble the extracellular matrix functioning as a temporary structure for cell proliferation and reconstruction of new organs and tissues. To evaluate the potential use of scaffolds as a biomaterial, this work proposes the development and characterization of polyurethane (PU), poly(D,L-lactic acid) (PDLLA) and polyurethane/poly(d,l-lactic acid) (PU/PDLLA) scaffolds produced by gas foaming technique. The neat polymers and the blends were characterized, in film form, by gel permeation chromatography (GPC), thermogravimetry (TG), differential scanning calorimetry (DSC) and field emission gun scanning electron microscopy (FEG-SEM). After supercritical fluid technology, in scaffolds form, the samples were characterized by FEG-SEM, pore size, density, cytotoxicity and cell adhesion. For film characterization the PU/PDLLA sample presented intermediate characteristics compared to the neat polymers, exhibiting the behavior of both polymers in the sample without phase separation in the FEG-SEM micrograph and bimodal molar weight distribution by GPC. The scaffolds showed interconnectivity and pore size of 141 µm ±â€¯108 µm for PUsc and 52 µm ±â€¯32 µm for PDLLAsc. The PU/PDLLAsc exhibited a bimodal structure in which the PU in the mixture revealed pores of 75 µm ±â€¯57 µm, while for PDLLA, the pore size was 19 µm ±â€¯12 µm. In vitro tests confirmed the adhesion of L929 cells to PUsc, PDLLAsc and PU/PDLLAsc, showing no cytotoxic effect. Finally, it can be concluded that it is possible to produce PU, PDLLA and PU/PDLLA scaffolds by supercritical fluid, which may be applied as biomaterials.
