Formulation and evaluation of carrot seed oil-based cosmetic emulsions

The present study deals with the evaluation of antiaging potential of carrot seed oil-based cosmetic emulsions. Briefly, cosmetic emulsions composed of carrot seed oil in varying proportions (2, 4, and 6% w/v) were prepared using the hydrophile–lipophile balance (HLB) technique. Coconut oil, nonionic surfactants (Tween 80 and Span 80), and xanthan gum were used as the oil phase, emulgent, and emulsion stabilizer, respectively. The formed emulsions were evaluated for various physical, chemical, and biochemical parameters such as the zeta potential, globule size measurement, antioxidant activity, sun protection factor (SPF), skin irritation, and biochemical studies. The zeta potential values ranged from ?43.2 to ?48.3, indicating good stability. The polydispersity index (PDI) of various emulsion formulations ranged from 0.353 to 0.816. 1,1-Diphenyl-2-picrylhydrazyl- (DPPH) and nitric oxide-free radical scavenging activity showed the antioxidant potential of the prepared carrot seed oil emulsions. The highest SPF value (6.92) was shown by F3 having 6%w/v carrot seed oil. Histopathological data and biochemical analysis (ascorbic acid (ASC) and total protein content) suggest that these cosmetic emulsions have sufficient potential to be used as potential skin rejuvenating preparations.     

eCASH理念结合早期活动在ICU机械通气患者的应用研究

目的探讨eCASH理念结合早期活动在ICU机械通气患者中的应用效果。方法将96例ICU机械通气患者按入院时间分为对照组和观察组各48例,对照组给予常规镇痛镇静及护理,观察组实施基于eCASH理念的舒适化浅镇静管理结合早期活动。结果观察组谵妄发生率和ICU获得性衰弱发生率显著低于对照组,MRC肌力评分显著高于对照组,机械通气时间和ICU住院天数显著短于对照组(P0.05,P0.01)。结论 eCASH理念结合早期活动应用于ICU机械通气患者,可降低患者谵妄和ICU获得性衰弱,缩短机械通气和ICU入住时间,促进患者康复。     

舒适护理在妊娠合并症患者中的效果评价

目的评价舒适护理在妊娠合并症患者中的效果。方法选取本院2017年1月-2018年10月收治的妊娠合并症患者60例,将其随机分为两组,各30例。对照组实施常规护理,基于此观察组实施舒适护理。比较两组妊娠合并症发生情况及满意度。结果在妊娠合并症方面,观察组发生率为6.67%较对照组33.33%明显更低,且P<0.05。在满意度方面,观察组为96.67%较对照组70.00%明显更高,且P<0.05。结论舒适护理在妊娠合并症患者中的效果显著,即可有效减少患者合并症,且能提升其满意度。     

Effects of a projector-based hybrid virtual reality on pain in young children with burn injuries during hydrotherapy sessions: A within-subject randomized crossover trial

AimThe aim of this study was to examine the effect of a water-friendly Projector-Based Hybrid Virtual Reality (VR) dome environment combined with standard pharmacological treatment on pain in young children undergoing burn wound care in hydrotherapy.MethodsThis study was a prospective, within-subject crossover trial of 38 children aged 6 months to 7 years old (mean age = 1.8 years old). Each hydrotherapy procedure was divided into two equivalent wound care segments (No hybrid VR during one segment vs. Hybrid VR during the other segment, treatment order was randomized). Pain was measured using the 0–10 FLACC (Face, Legs, Activity, Cry Consolability scale) and the 0–10 NRS-obs (Numerical Rating Scale-obs).ResultsProjector-Based Hybrid VR significantly reduced procedural pain levels measured by the FLACC (p = 0.026) and significantly increased patients' comfort levels (p = 0.002). Patients' pain levels rated by the nurses using the NRS-obs were non-significant between both groups (p = 0.135). No side effects were reported.ConclusionProjector-Based Hybrid VR helped in reducing the pain related to hydrotherapy procedures in young children with burn wound injuries. This is the first study using virtual reality distraction with young children, and our findings are especially important because a large percentage of pediatric burn patients are very young. Additional research and development are recommended.Trial registrationClinicalTrials.gov, NCT02986464, registered on June 12, 2016.     

Perception of Labial Size and Objective Measurements-Is There a Correlation? A Cross-Sectional Study in a Cohort Not Seeking Labiaplasty

IntroductionPoor genital self-image is a common phenomenon leading to an increasing interest in female genital surgery over the last years.AimThe aim was to correlate objective measurements of the labia minora with the individual subjective perception of the labial size.MethodsIn a cross-sectional study with 200 premenopausal women (median age 33.5 years) presenting for gynecological issues other than vulvar diseases, labial width and length were measured, and psychological and physical complaints were assessed. Multivariable logistic regression analyses were performed to identify factors that influenced self-reported complaints and subjective perception of labia size.Main Outcome MeasureThe main outcome measure was labial appearance (width and length in mm, color), subjective perception of the labial size, and complaints.ResultsThe median width of the labia minora was 19.0 mm (interquartile range = 12.6–27.5), and the median length was 35.5 mm (interquartile range = 27.8–48.9). The objective size of the labia was significantly associated with womens' subjective perception of the labial size, but not with self-reported complaints. Nearly one-third of the women (n = 53, 27%) reported complaints of their labia minora which were mainly physical (n = 41, 77%) or a combination of physical and psychological problems (n = 9, 17%), while only a small group reported experiencing only psychological complaints (n = 3, 6%). Predictors of complaints were previous cosmetic surgery and the subjective perception of the labia size. The latter was significantly associated with discomfort during intercourse and when visiting a sauna and by labia minora that protruded over the labia majora.Clinical ImplicationsCutoff values to define labial hypertrophy and to justify labial reduction surgery should be avoided.Strength & LimitationsThis is a large sample of labial measurements in women not seeking labiaplasty. Standardized and validated questions regarding quality of life, sexuality, and body image could have provided more insight into psychological aspects.ConclusionThese data demonstrate the variability of labial anatomy and its perception.Widschwendter A, Riedl D, Freidhager K, et al.
