[PMID: 38016202 DOI: 10.1016/j.ejon.2023.102471] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 11/13/2023] [Accepted: 11/16/2023] [Indexed: 11/30/2023]
Abstract
PURPOSE The aim of this study is to assess the impact of lavender oil on odor elimination, ostomy adjustment and quality of life outcomes in patients with permanent colostomy. Specifically, the study aims to compare the outcomes of an experimental group receiving lavender oil intervention with those of a control group. METHODS A randomized controlled trial design was employed, including an experimental group receiving lavender oil intervention and a control group receiving standard care. The study participants were patients with permanent colostomy. Various variables were assessed, including odor scale, work and social functioning, sexuality and body image, stoma function, financial concerns, acceptance, anxiety/preoccupation, social engagement and anger. RESULTS The post-scores assessment showed significant differences between the experimental and control groups in all variables. The experimental group exhibited significantly more positive outcomes concerning the reduction of odor (p<0.001), performance in the workplace (p<0.001), body image connected to sexuality (p<0.001), stoma functionality (p<0.001), financial worries (p=0.005), acceptance levels (p<0.001), anxiety levels (p<0.001), social involvement (p<0.001), and irritability (p<0.001). Effect sizes were substantial (=0.88-0.98 in all variables but one), indicating significant differences in average scores before and after the intervention. CONCLUSION The findings of this study suggest that lavender oil intervention effectively improved odor elimination, ostomy adjustment and quality of life outcomes in patients with permanent colostomy.

Beneficial effects of Silexan on co-occurring depressive symptoms in patients with subthreshold anxiety and anxiety disorders: randomized, placebo-controlled trials revisited. Eur Arch Psychiatry Clin Neurosci 2023; 273:51-63. [PMID: 35262795 PMCID: PMC9958187 DOI: 10.1007/s00406-022-01390-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Accepted: 02/01/2022] [Indexed: 11/03/2022]
Abstract
Silexan is a proprietary active substance produced from Lavandula angustifolia, with proven anxiolytic efficacy in subthreshold and generalized anxiety disorder as well as in mixed anxiety and depressive disorder with beneficial impact on anxiety-related sleep disturbances. The pharmacological profile and clinical observations suggest that Silexan may also have an antidepressant effect. To investigate the effect of Silexan on co-occurring depressive symptoms, we present a meta-analysis of the five placebo-controlled clinical trials hitherto performed with Silexan in subthreshold anxiety (n = 3) and anxiety disorders (n = 2). Patients of all trials received Silexan 1 × 80 mg/day or placebo for 10 weeks according to random assignment. Assessment of the antidepressant effect was based on item 'depressed mood' from the Hamilton Anxiety Rating Scale (HAMA) administered in all trials and on the total scores of the Montgomery Åsberg Depression Rating Scale (MADRS) or the Hamilton Depression Rating Scale (HAMD) used in three trials. After 10-week treatment, patients receiving Silexan showed significantly more pronounced score reduction for HAMA item 'depressed mood' than those in the placebo group (p = 0.01). Significant superiority of Silexan over placebo could also be shown for mean MADRS or HAMD total score reduction (three studies; p < 0.01). Silexan-treated patients with more severe depressive symptoms at baseline showed more pronounced improvements than those with milder symptoms. Our meta-analysis clearly shows that Silexan has a beneficial effect on co-occurring depressive symptoms in patients with subthreshold anxiety and anxiety disorders and may, hence, lead to important therapeutic implications for depressive disorders.

Abstract
Lavandula angustifolia Mill. is an aromatic herb of the Lamiaceae family, which has been widely used by humans for many centuries. In the current study, we treated L. angustifolia samples with various concentrations of ZnO and Fe2O3 nanoparticles in the presence/ absence of NaCl salinity stress to evaluate the composition of essential oils, genetic structure, glandular trichome density and cellular Zn2+ and Fe2+ contents. We used Inter Simple Sequence Repeat (ISSR) molecular markers to investigate the parameters of genetic diversity among the treated samples. Furthermore, the hydro-distilled essential oil from the aerial parts of the samples was subjected to GC and GC / MS analyses. SPSS ver. 15, PAST, PopGene, and GenAlex software were employed for statistical analyses. Intracellular concentrations of Fe2+ and Zn2+ differed under various concentrations of nanoparticles and salinity treatments, and a significant negative correlation was observed between these elements, however, nanoparticles treatment significantly increased intracellular concentrations of iron and zinc ions. We found four types of glandular trichomes on the surface of the leaf of the treated plants, and the ANOVA test revealed a significant variation for most of them. Meanwhile, the short-stalked capitate trichomes were the most frequent in most of the evaluated samples. The main and trace essential oil compounds were the same among the treated plants, meanwhile, their percentages varied among the samples. The percentages of 1,8- cineole and camphor decreased in treated plants, which affects the quality of essential oils. Parameters of genetic diversity differed among the treated samples. Furthermore, the AMOVA test demonstrated a significant genetic variation that its substantial part belonged to among treated samples. These findings revealed that the treatment of nanoparticles and salinity stress strongly influenced the genetic diversity, trichomes density, iron and zinc ions content in lavender plants.

Abstract
Essential oils (EOs) have been traditionally used as ancient remedies to treat many health disorders due to their enormous biological activities. As mainstream allopathic medication currently used for CNS disorders is associated with adverse effects, the search to obtain safer alternatives as compared to the currently marketed therapies is of tremendous significance. Research conducted suggests that concurrent utilization of allopathic medicines and EOs is synergistically beneficial. Due to their inability to show untoward effects, various scientists have tried to elucidate the pharmacological mechanisms by which these oils exert beneficial effects on the CNS. In this regard, our review aims to improve the understanding of EOs' biological activity on the CNS and to highlight the significance of the utilization of EOs in neuronal disorders, thereby improving patient acceptability of EOs as therapeutic agents. Through data compilation from library searches and electronic databases such as PubMed, Google Scholar, etc., recent preclinical and clinical data, routes of administration, and the required or maximal dosage for the observation of beneficial effects are addressed. We have also highlighted the challenges that require attention for further improving patient compliance, research gaps, and the development of EO-based nanomedicine for targeted therapy and pharmacotherapy.

Abstract
Lavender, otherwise known as Lavandula angustifolia Mill., is widely used in landscaping, and its oil is a valuable raw material used in many industries. Therefore, new varieties of this plant are bred. The essential oil composition obtained from fresh flowers of thirteen new Ukrainian cultivars of L. angustifolia were analysed by GC-MS, and eighty-two components were identified. Linalool and linalyl acetate were principal constituents of all of the samples, and ranged from 11.4% to 46.7% and 7.4% to 44.2%, respectively. None of the studied samples fulfilled the requirements of Ph. Eur. and ISO 3515:2002. The main reason was a high content of α-terpineol (0.5-4.5%) and/or terpinene-4-ol (1.2-18.7%). Our results are in line with multiple researchers showing that the studied lavender oils do not comply with the industry standards despite their authenticity. We also investigated the effect of the growth year on the chemical composition of five tested cultivars grown on the same plots and noticed a considerable variability between years. The obtained experimental data did not show a significant inter-year trend for the content changes of the major components. Our results allow us to deeply characterize the new cultivars and evaluate their oil for a possible use in the industry, or to designate them for future selective breeding.

Abstract
Ever more research results demonstrate that human health and wellbeing are positively affected by stays in and/or exposure to natural areas, which leads, among other things, to a reduction in high stress levels. However, according to the studies, these natural areas must meet certain qualities. The qualities that are considered to be most health promoting are those that humans perceive in a positive way. Theories about how natural areas can reduce people's stress levels and improve their coping skills have mainly focused on how certain natural areas that are perceived as safe reduce the activity of the hypothalamic-pituitary-adrenal axis and consequent reduction of cortisol levels. This article discusses studies containing descriptions of how participants in rehabilitation perceive and react to natural phenomena. The common core variable in the analyzed studies was the experience of calm and connection, and this experience was associated with a reduction in stress levels and with being able to develop health and coping skills. We suggest that this experience provides a possible role for the oxytocinergic system to act as a physiological mediator for the positive and health-promoting effects in humans caused by nature. The theory is mainly based on analogies framed by theories and data from the fields of environmental psychology, horticulture, landscape architecture, medicine, and neuroscience. Oxytocin promotes different kinds of social interaction and bonding and exerts stress-reducing and healing effects. We propose that oxytocin is released by certain natural phenomena experienced as positive to decrease the levels of fear and stress, increase levels of trust and wellbeing, and possibly develop attachment or bonding to nature. By these effects, oxytocin will induce health-promoting effects. In situations characterized by low levels of fear and stress in response to release of oxytocin, the capacity for "growth" or psychological development might also be promoted. Such an instorative effect of nature, i.e., the capacity of nature to promote reorientation and the creation of new coping strategies, might hence represent an additional aspect of the oxytocin-linked effect profile, triggered in connection with certain nature phenomena. We conclude by proposing that the stress-relieving, health-promoting, restorative, and instorative effects of nature may involve activation of the oxytocinergic system.

Abstract
OBJECTIVES Many patients experience anxiety and stress before surgery. Anxiety is also different in men and women so that the prevalence of anxiety disorders in women is higher than men. The present study aimed to compare the effect of inhalation aromatherapy on emotional distress of men and women before surgery. METHODS This study conducted as a randomized, single blind, placebo-controlled, prospective and clinical trial. It was performed in hospitals affiliated to Shiraz University of Medical Sciences. 90 patients were selected as candidates for surgery and were divided into two intervention groups and one control group. Patients completed the State-Trait Anxiety Inventory questionnaire before the intervention. Patients completed the State-Trait Anxiety Inventory questionnaire (STAI) after 20 min of intervention. Then the data were analyzed using SPSS software, version 16. The significance level in all testes was set at <0.05. RESULTS Relatively severe anxiety was not observed in men after intervention with lavender and spring orange. In women, relatively severe anxiety was not observed after the intervention with lavender, but in the spring orange group, only in 6.7% of people, relatively severe anxiety and traits were observed, which has decreased compared to before the intervention. In addition, the severity of anxiety in women in the control group increased after placebo intervention (p<0.05). CONCLUSIONS The results showed that inhalation of Citrus aurantium and lavender aroma reduces anxiety in male and female patients.
