TRP channels in cancer: Therapeutic opportunities and research strategies.

The influence of gut microbiota on transient receptor potential (TRP) channels has been identified as an important element in the development of gastrointestinal conditions, yet its involvement in cancer progression is not as thoroughly understood. This review explores the multifaceted roles of TRP channels in oncogenesis and emphasizes their significance in cancer progression and therapeutic outcomes. Critical focus was placed on the influence of traditional medicines, such as traditional Chinese medicine (TCM) related aromatic medicines, on TRP channel functions. Moreover, we explored the interplay between the gut microbiota and TRP channels in cancer signaling, highlighting the therapeutic potential of targeting this axis in cancer treatment. The impact of current therapies on TRP channel function was examined, demonstrating the need for a comprehensive understanding of how different modalities affect TRP channels in cancer. Technological advancements, including artificial intelligence (AI) tools and computer-aided drug development (CADD), have been discussed in the context of leveraging TRP channels for innovative cancer therapies. Future directions emphasize the potential applications of TRP channel research in advancing cancer treatment and enhancing patients' well-being.

The Effects of Spiritual Care with and Without Aromatherapy on the Sleep Quality of Prisoners Referred to the Emergency Department of the Prison Clinic in Iran: A Randomized Clinical Trial.

Rest and sleep are health fundamentals and essential phases of human life rhythms. Sleep disturbances can negatively affect an individual's physical and mental balance. Due to the psychological pressure resulting from problems, prisoners experience more sleep disturbances than other people. Therefore, this study aimed to compare the effects of spiritual care with and without aromatherapy on the sleep quality of prisoners in the emergency department of the central prison clinic in Sanandaj County. A single-blind clinical trial was conducted on 90 male prisoners of the emergency department of the central prison clinic in Sanandaj, Kurdistan-Iran, and they were randomly assigned to three groups: spiritual care (intervention 1), spiritual care with aromatherapy (intervention 2), and control group. Spiritual care and aromatherapy, along with spiritual care interventions, were performed using lavender essence for one month. Data collection was performed using a demographic checklist and the pittsburgh sleep quality index before and after the interventions. The collected data were analyzed using descriptive and analytical statistical methods in SPSS.26. The mean age of the prisoners was 34.99 ± 7.011 years, 75.6% had a diploma or lower education level, and 46.7% had been imprisoned for more than one year. At baseline, the mean sleep quality score was 9.33 ± 3.55 in intervention group 1, 9.53 ± 4.06 in intervention group 2, and 10.50 ± 3.59 in the control group, with no significant difference between the groups (p = 0.413). After the interventions, the mean sleep quality score was 8.40 ± 2.94 in intervention group 1, 7.86 ± 4.90 in intervention group 2, and 11.23 ± 3.81 in the control group, showing a significant difference between the groups (p = 0.002). According to findings, aromatherapy, along with spiritual care, significantly improved the sleep quality of prisoners (p = 0.003), but spiritual care alone was not effective (p = 0.137). Aromatherapy-based spiritual care improved the sleep quality of prisoners; hence, considering the congruency of spirituality with pleasant scents symbolizing cleanliness and aligning with human nature and religious recommendations, the combination of these two interventions can be used to enhance the sleep quality of prisoners.

The effects of aromatherapy and music on pain, anxiety, and stress levels in palliative care patients.

AIM: Pain and anxiety levels in palliative care patients negatively impact their quality of life, highlighting the need for research on non-pharmacological methods. This study aimed to evaluate the effects of music and aromatherapy interventions on pain, anxiety, and stress levels in these patients. MATERIAL AND METHODS: The research was designed as a single-blind, four-group, randomized controlled trial. The sample consisted of 88 patients hospitalized in a palliative care center (receiving palliative care services with terminal or advanced diseases). Patients were randomly assigned to four groups (n = 22, music, aromatherapy, music and aromatherapy, and control group). Patients in the experimental groups received the intervention to which they were assigned for 20 min each day for three consecutive days: music, aromatherapy, or music accompanied by aromatherapy. No intervention was applied to the control group. The patients' levels of pain, anxiety, and stress were assessed before and after the intervention using the Visual Analog Scale (VAS), the Facial Anxiety Scale (FAS), and the Distress Thermometer. RESULTS: No significant differences were found in the demographic characteristics of the groups (p > 0.05). The Wilcoxon Signed-Rank and Kruskal-Wallis tests indicated statistically significant differences in pre- and post-intervention scores for VAS, FAS, and Distress across all experimental groups on all follow-up days (p < 0.05). CONCLUSION: Implementing music, aromatherapy, and their combination effectively reduced pain, anxiety, and stress levels in palliative care patients, suggesting these non-pharmacological interventions can improve their quality of life.

The effects of aromatherapy massage given to patients after colorectal cancer surgery on symptom management: A randomized controlled study.

BACKGROUND AND PURPOSE: It was aimed to investigate the effects of massage with or without aromatherapy given to patients after colorectal cancer surgery on symptom management in the first three postoperative days. MATERIALS AND METHODS: This study was carried out with a pretest-posttest randomized controlled design. The study included the aromatherapy massage group (AG; n = 30), the classical massage group (MG; n = 30), and one control group (CG; n = 30). A blend of sweet almond oil, lavender, chamomile, and ginger oil was used in AG. Massage was applied to the foot area, and 20 min of classical massage was performed. Before the pretest, the participants were blinded by not informing them about their group allocations. The analyses were carried out using parametric methods. RESULTS: Postoperative pain varied significantly over time in all three groups (AG: p = 0.007; η2 = 0.150/MG: p = 0.008; η2 = 0.559/CG: p = 0.017; η2 = 0.132). Anxiety was found to differ between CG and AG and between CG and MG (p < 0.05). In all three groups, nausea-vomiting scores significantly decreased over time (AG: p = 0.002; η2 = 0.211/MG: p = 0.004; η2 = 0.164/CG: p = 0.021; η2 = 0.125). Sleep quality was significantly higher in the massage groups than in the control group only on the second postoperative day (p = 0.011). CONCLUSION: Aromatherapy massage had no significant effect on pain, fatigue, nausea, or vomiting compared to MG and CG, and sleep quality was higher in the massage groups compared to CG only on the second postoperative day. On the first three postoperative days, the post-intervention anxiety levels of AG and MG were lower than those of CG. CLINICALTRIALS: GOV.ID: NCT04810299.

Effect of Lavender Oil Leg Massage on Physical, Cognitive, and Psychological Variables of Patients with Hypertension: A Randomized Controlled Trial.

Background: Hypertension (HTN) is one of the most important non-communicable risk factors that cause cardiovascular diseases. Complementary therapies including massage and aromatherapy are widely used in the management of HTN. However, studies on aromatherapy massage in HTN are limited. Thus, this study was conducted to evaluate the effect of lavender oil leg massage on physical (cardiopulmonary function), cognitive, and psychological variables of patients with HTN. Materials and methods: A parallel-group randomized controlled trial, comprising 100 HTN patients aged 44.99 ± 5.39 years who were recruited and randomly divided into the study group (SG) and control group (CG), was conducted. The SG received lavender oil leg massage, while the CG received supine rest for 20 min. Outcome variables like blood pressure (BP), pulse rate (PR), random blood sugar (RBS) level, oxygen saturation, pulmonary function, oral temperature, trail making test (TMT) A and B, and state anxiety and mindfulness were assessed before and after the intervention. Results: The within-group analysis showed a significant improvement in systolic blood pressure, diastolic blood pressure, PR, RBS, TMT-A, TMT-B, and state mindfulness both in the SG and CG. However, a significant reduction in state anxiety was observed only in the SG unlike the CG. Moreover, the between-group analysis showed a significant improvement in state mindfulness and state anxiety in the SG compared to the CG. Conclusion: The results of this study suggest that lavender oil leg massage is effective in reducing BP and RBS, and improving cognitive function in hypertensive patients. In addition, it is more effective in reducing anxiety and improving mindfulness than rest in supine position in patients with HTN.

The Role of Essential Oils on Sleep Quality and Other Sleep-related Issues: Evidence from Clinical Trials.

Essential oils (EOs) are a volatile mixture of bioactive compounds extracted from aromatic plants. The composition of EOs varies, which majorly depends on the extraction methods and plant parts. Aromatherapy using EOs has been reported for its several beneficial effects in humans. Aromatherapy is considered a complementary and/ or adjuvant therapeutic approach for treating several illnesses, especially to improve mental health and well-being. The incidence of sleep disorders, specifically insomnia, is nowadays increased, possibly due to urbanization and lifestyle. The studies showed that EOs-based treatments using lavender EO, bergamot EO, cinnamon EO, and rosemary EO (alone or in combinations) could improve sleep quality, duration, and deprivation in healthy subjects and patients, those who suffer from sleep-related issues. The current manuscript details the outcomes of EO-based treatments on the sleep quality of humans and the possible mechanisms associated with the health-promoting properties of EOs. Also, the toxicity and adverse effects of EOs have been discussed. The study indicated that EOs are potent adjuvant therapeutic candidates to manage mood-associated complications in humans. Moreover, the aromatherapeutic field requires detailed studies on toxicity and dose determination, which could provide safe and effective therapeutic results.

Objective: To evaluate studies related to pain management associated with arteriovenous fistula cannulation among children. METHODS: The systematic review comprised literature search on Embase, ProQuest, Science Direct, Scopus, SpringerLink and Wiley Online databases for studies published in English between 1998 and 2021. The search used key words, including pain management OR analgesia AND child OR paediatric AND haemodialysis OR dialysis AND arteriovenous fistula OR arteriovenous fistula cannulation OR fistula needle OR arteriovenous fistula insertion OR needle insertion. The quality of the studies was evaluated using the Joana Briggs Institute checklist. General characteristics of the and pain outcomes were noted. RESULTS: Of the 2,877 studies initially identified, 8(0.27%) were analysed; 7(87.5%) quasi-experimental and 1(12.5%) randomised controlled trial. Overall, there were 283 participants aged 6-18 years. The strategies used for reducing arteriovenous fistula puncture-related pain among children undergoing haemodialysis included cryotherapy, lidocaine agents, virtual reality (VR), guided visualisation, balloon inflation, aromatherapy, and other programmed distractions. The strategies had a positive effect on reducing arteriovenous fistula cannulation-related pain among children. Conclusion: Non-pharmacological pain management is an easier, simpler, inexpensive and more effective method of atraumatic care among children undergoing haemodialysis.

Comparative efficacy of non-pharmacological interventions for anxiety in adult intensive care unit patients: A systematic review and network meta-analysis.

BACKGROUND: The primary goal of the intensive care unit is to the anxiety of conscious patients is often ignored in the care unit. AIM: The purpose of this study was to assess the efficacy of various non-pharmacological therapies for anxiety disorders in adult patients in the intensive care unit, in order to enhance humanistic care in the intensive care unit and to promote the patients' physical and mental recovery together. STUDY DESIGN: We conducted a systematic and comprehensive search of the literature in five databases (including the Cochrane Library, PubMed, EBSCO, Web of Science, and Embase) covering nearly a decade for randomized controlled trials of non-pharmacological therapies to reduce anxiety in adult intensive care unit patients. Two researchers independently assessed the quality of the literature, collected and condensed the data, and used STATA software to perform a network meta-analysis. The ranking probabilities for each intervention were calculated using the Surface under the Cumulative Ranking (SUCRA) method. The study protocol was registered with PROSPERO. RESULTS: This study ultimately included 26 randomized controlled trials involving 2791 adult ICU patients. Non-pharmacological interventions for anxiety in adult ICU patients included music therapy, aromatherapy, ICU diary, virtual reality, massage therapy, monitoring room diary, and health education. when compared to the control group (usual care), aromatherapy + music therapy [MD = -2.65, 95% CI (-4.76, -0.54)] (P = 0.0137) and music therapy [MD = -1.77, 95% CI (-3.40, -0.13)] (P = 0.0338) were superior in reducing anxiety in adult ICU patients. The results of the network meta-analysis showed that aromatherapy combined with music therapy significantly alleviated anxiety in adult ICU patients (SUCRA: 99.8%). CONCLUSIONS: Music therapy combined with aromatherapy has demonstrated superior effectiveness compared to other non-pharmacological interventions for reducing anxiety in awake adults in the ICU. However, the underlying mechanisms of this combined therapy require further exploration. RELEVANCE TO CLINICAL PRACTICE: Future research on the use of music therapy combined with aromatherapy in the care unit may help reduce anxiety in patients while fostering their physical and mental healing; however, individual variances and unique clinical circumstances must be considered.

Assessing the Anxiolytic and Relaxation Effects of Cinnamomum camphora Essential Oil in University Students: A Comparative Study of EEG, Physiological Measures, and Psychological Responses.

Background: Cinnamomum camphora is a commercially important tree species in China, and it's also a common native tree in the forests of southern China. However, literature on the impact of Cinnamomum camphora essential oil (CCEO) on human psychophysiological activity is scarce. Hence, the primary objective of this study was to examine the effect of exposure to CCEO on the functioning of the human autonomic nervous system, electroencephalographic (EEG) activity, and emotional state. Methods: Forty-three healthy university students participated. The data collected included heart rate (HR), blood pressure (BP), pulse rate, blood oxygen saturation (SpO2), electroencephalographic (EEG) activity, and the results of the Profile of Mood States (POMS) test. Results: A drop in diastolic pressure (DBP) and pulse rate was also noticed after participants inhaled CCEO. Furthermore, EEG studies have demonstrated notable reductions in absolute beta (AB), absolute gamma (AG), absolute high beta (AHB), and relative gamma (RG) power spectra during exposure to CCEO. Conversely, the relative theta (RT) and power spectra values showed a significant increase. Additionally, the finding from POMS indicated that the fragrance evoked positive emotions and suppressed negative feelings. Conclusion: The results suggest that exposure to CCEO may promote mental and physical relaxation, facilitate cognitive processes such as memory and attention, and enhance mood states.

Evaluation of lavender and rose aromatherapies on the success of inferior alveolar nerve block in symptomatic irreversible pulpitis: A randomized clinical trial.

Trial design: This is a prospective, block-randomized, blinded, multiple arm and parallel-group superiority clinical trial. Methods: Seventy-eight patients satisfying the recruitment standards, were randomly allocated into three groups as follows: Group I (n = 26) - Inferior alveolar nerve block (IANB) devoid of aromatherapy (AT); Group II (n = 26) - IANB with lavender AT and Group III - IANB with rose AT (n = 26) with the help of the ultrasonic aroma diffuser (with respective oils)for 20 min/2 h in operatories 1,2 and 3 respectively. For AT, 3-4 drops of lavender and rose-conditioned oils were added from a 100 ml solution containing 100 mg of these medicinal plants. The pre-operative (PRO) and access opening (AO) pain as well as the anxiety of patients were recorded using the Visual Analog Scale (VAS) and Modified Dental Anxiety Scale (MDAS) respectively. Data thus obtained was entered into the Excel sheet and subjected to statistical tests (analysis of variance and paired t-test). The p-value less than 0.05 was considered statistically significant. Results: Group I showed non-significant disparity between PRO and AO for both VAS as well as MDAS (p = 0.62, p = 0.71). However, group II (p = 0.04, p = 0.02) and group III (p = 0.03, p = 0.01) revealed significant differences between PO - AO VAS and MDAS. MDAS and VAS intergroup comparison revealed a significant difference among groups I and II (p = 0.03, p = 0.04), and groups I and III (p = 0.02, p = 0.03). However non-significant disparity was observed among groups II and III (p = 0.85, 0.34). Moreover, there was a statistically significant reduction in anxiety levels in females compared to males after rose AT (p = 0.02). Nevertheless, groups I and II did not show any gender predilection for anxiety as well as pain. Conclusion: Alleviation of dental anxiety as well as reduction in pain during AO of teeth with SIP can be achieved using Lavender and rose AT. In female patients, rose AT can be preferred over lavender AT.

The effect of aromatherapy on post-stroke depression: study protocol for a pilot randomized controlled trial.

Background: Post-stroke depression (PSD) is a prevalent psychiatric disorder affecting about one-third of stroke survivors, significantly hindering recovery and quality of life. PSD also imposes a substantial burden on caregivers and healthcare systems. Aromatherapy has shown promise in alleviating depression, anxiety, and sleep disorders. This pilot randomized controlled trial aims to assess the feasibility and preliminary efficacy of mixed herb aromatherapy in treating PSD. Feasibility outcomes encompass recruitment, intervention adherence, assessment completion and safety assessment. Secondary outcomes include evaluations of depression, anxiety, cognitive function, sleep quality, quality of life, and brain function using EEG and fNIRS. Methods: This single-blind pilot randomized controlled trial will be conducted at the Second Rehabilitation Hospital of Shanghai, enrolling ninety-nine post-stroke patients with PSD. Participants will be randomized into three groups: a Non-Active Control Group receiving standardized rehabilitation therapy, a CBT Group receiving conventional rehabilitation with bi-weekly CBT sessions, and an Aromatherapy Group receiving conventional rehabilitation with daily aromatic inhalation sessions. Interventions will last for four weeks, with efficacy assessed at baseline, post-intervention, and one month post-intervention. Rating scales will be used to measure changes in depression, sleep quality, cognitive function, and quality of life. EEG and fNIRS will specifically be used to measure changes in cerebral cortex activity and their correlations with depression. Feasibility will be evaluated through recruitment, intervention adherence, assessment completion and safety assessment. Discussion: This pilot study highlights the potential of mixed herb aromatherapy inhalation for treating PSD, addressing limitations of CBT by promoting self-management. While demonstrating feasibility through recruitment, adherence, assessment completion and safety assessment, the study also acknowledges limitations such as unequal intervention times, the lack of physical function data. And the use of culturally relevant plant powders may enhance compliance but limits generalizability. Despite these constraints, the study provides valuable preliminary data and insights into the mechanisms of aromatherapy, encouraging further research and development of effective PSD treatments.

Nursing strategies for enhancing calm in older Arabs with dementia: integrating Snoezelen methods, aromatherapy, and personal items to reduce agitation.

BACKGROUND: Agitation significantly impacts Arab elders with dementia. Multisensory stimulation, such as Snoezelen, shows promise but lacks exploration in Arab contexts. OBJECTIVE: Evaluate a culturally adapted multisensory intervention-combining Snoezelen, aromatherapy, and personal items-on agitation in Arab elders with dementia. METHODS: A quasi-experimental design assessed 31 patients receiving the intervention against 31 controls. Agitation, quality of life, and neuropsychiatric symptoms were measured using the Cohen-Mansfield Agitation Inventory (CMAI) and the Neuropsychiatric Inventory (NPI). RESULTS: The intervention group exhibited notable reductions in CMAI scores for aggression and agitation behaviors (p < 0.001) and improvements in quality of life and NPI scores for agitation/aggression and depression/dysphoria (p < 0.001). CONCLUSION: This culturally tailored multisensory approach effectively reduced agitation and improved well-being in Arab dementia patients. The findings advocate for further research and suggest such interventions can be beneficial in culturally diverse dementia care settings. TRIAL REGISTRATION: ClinicalTrials.gov, ID NCT06216275.

Efficacy of Aromatherapy Against Behavioral and Psychological Disturbances in People With Dementia: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVES: Behavioral and psychological symptoms of dementia (BPSD) are common in people with dementia. Aromatherapy may reduce the frequency and severity of BPSD. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of aromatherapy in relieving BPSD and improving functional ability in people with dementia. DESIGN: Systematic review and meta-analysis. SETTING AND PARTICIPANTS: Patients with dementia receiving aromatherapy. METHODS: A literature search was conducted using PubMed, Embase, and Cochrane Library for RCTs published before March 2024 comparing aromatherapy with control treatments in patients with dementia. RESULTS: There were 15 trials involving 821 patients. Overall, significant reduction in BPSD was observed after 1 month of aromatherapy treatment. Among 15 trials, 9 reported the Cohen-Mansfield Agitation Inventory (CMAI) score, and 7 evaluated the Neuropsychiatric Inventory (NPI) score. The meta-analysis showed significant improvement in CMAI score (weighted mean difference [WMD] -6.31, 95% CI -9.52 to -3.11) and NPI score (WMD -8.07, 95% CI -13.53 to -2.61) in patients receiving 3 to 4 weeks of aromatherapy compared with the control group. Four of the 15 trials reported improvement in depressive mood and 3 trials reported no significant improvement in functional ability. CONCLUSIONS AND IMPLICATIONS: In conclusion, aromatherapy is a safe and viable nonpharmacologic treatment to improve BPSD in people with dementia and its combination with massage showed higher efficacy.

Evaluating the relaxation effects of Shikuwasa (Citrus depressa Hayata) essential oil inhalation in young female adults: Study protocol for a randomised controlled trial.

Introduction: The essential oil of Shikuwasa (Citrus depressa Hayata) primarily contains limonene and γ-terpinene, which have potential applications in stress management and relaxation. However, the psychological or physiological relaxation effects of Shikuwasa essential oil on humans are still unknown. This study aims to investigate the short-term relaxation effects of Shikuwasa essential oil, one of the less-studied varieties, compared to inhaling odour-free air in young female adults. Methods: and analysis: This study is a two-arm, parallel-group, open-label, randomised controlled superiority trial. Forty young female adults will be assigned with a 1:1 allocation ratio to either the Shikuwasa essential oil inhalation group or the odour-free air inhalation group. The primary outcome measure will be subjective tense arousal (subscale of the Japanese version of the University of Wales Institute of Science and Technology Mood Adjective Checklist). Secondary outcomes include objective measures: miosis rate and peripheral skin temperature for evaluating autonomic nervous activity, and cerebral blood flow (assessed using near-infrared spectroscopy) for evaluating central nervous activity. Since these objective outcome measures cannot be performed at the same time, we divide our experiment into three phases and participants will inhale sample vials for 2 min in each experiment. We will also evaluate individual preferences/impressions regarding inhaled samples and any adverse events. Ethics and dissemination: The study protocol has been reviewed and approved by the Research Ethics Committee of the Faculty of Medicine, University of Miyazaki (reference no: I-0074). The findings of this study will be disseminated to academic and professional audiences via publications in peer-reviewed journals and presentations at academic conferences, and to the broader public via public talks and media/press releases. All study findings, whether negative or positive, will be reported. Trial registration: UMIN Clinical Trials Registry (UMIN-CTR), UMIN000053914. Prospectively registered on March 20, 2024.

The effect of aroma lymphatic tressage on taxane-induced lower-extremity edema in breast cancer patients.

BACKGROUND: Taxanes are effective chemotherapy drugs for breast cancer care, but adverse effects pose a significant challenge in cancer treatment. Taxane-induced fluid retention and lower-extremity edema are two of the important dose-limiting toxicity and result in decreased quality of life (QoL). However, there is no standard of care to alleviate the symptoms. We conducted a clinical study to assess the efficacy of short-term aroma lymphatic tressage therapy (ALTT) in reducing taxane-induced edema in breast cancer patients. METHODS: In this phase 2 clinical trial, patients with edema of CTCAE grade 2 or higher were enrolled and conducted 8 sessions of ALTT. The primary endpoint was to determine the proportion of patients with a reduction in lower extremity circumference of 3% or more before and 6 weeks after starting ALTT. The change in QoL was assessed as the secondary endpoint using QoL questionnaires. RESULTS: A total of 37 breast cancer patients completed the protocol and were analyzed. The median sum of the 3-point circumference (thigh, calf, and ankle) was 230.8 cm (IQR 218-243) in the baseline and 220.2 cm (IQR 212-236) at the end of the study. The average decrease of circumference was 3.8%. About, 23 patients (62%) experienced a circumference decrease of 3% or more. An improvement in every scale of FACT-TAXANE and EORTC-QLQ-C30 was observed when comparing questionnaire results before and at the end of the intervention (P < 0.0001). CONCLUSION: Eight sessions of ALTT over 4 weeks were effective in reducing lower-extremity edema and resulted in improvement of QoL in patients with breast cancer.

Comparing the Effects of Lavender Aromatherapy and Mindfulness-Based Cognitive Therapy on Sexual Function in Women in Iran.

OBJECTIVE: To compare the effects of aromatherapy with lavender and mindfulness-based cognitive therapy for sexuality (MBCT-S) on female sexual function. DESIGN: Randomized controlled trial. SETTING: Health centers in Roudan city, Iran. PARTICIPANTS: Sixty married women, ages 18 to 45 years, were recruited using the Female Sexual Function Index (FSFI). Participants were selected from health centers in 2022 via convenience sampling. INTERVENTION AND MEASUREMENTS: Upon their completion of a demographic checklist and the FSFI as a pretest, participants were divided into three groups, including lavender aromatherapy (n = 20), MBCT-S (n = 20), and control (n = 20) through random selection with permutation blocks. All groups completed FSFI as a posttest. Data were analyzed by SPSS 26 using chi-square, Wilcoxon, Kruskal-Wallis, and Mann-Whitney statistical tests. RESULTS: There was no statistically significant difference among the three groups before the intervention (p = .652), but there was a significant difference among them after the intervention (p = .001). There was a significantly positive difference between the intervention groups and the control group (p < .001). A significant relationship was observed among the three groups in sexual desire, pain, satisfaction, lubrication, and arousal. The mean scores of the posttest in sexual desire, pain, satisfaction, and lubrication were positively higher in the MBCT-S group than in the aromatherapy group, and both intervention groups showed the same effect for sexual arousal. Aromatherapy and counseling had no significant effect on improving sexual orgasm. CONCLUSION: MBCT-S can be used to improve many aspects of female sexual function, except for orgasm disorders; aromatherapy may improve sexual arousal.

Eucalyptus Essential Oil Inhibits Cell Infection by SARS-CoV-2 Spike Pseudotyped Lentivirus.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains a public health concern due to infections with new SARS-CoV-2 variants. Therefore, finding effective preventive and therapeutic treatments against all SARS-CoV-2 variants is of great interest. In this study, we examined the capacity of eucalyptus essential oil (EEO) and eucalyptol (EOL) to prevent SARS-CoV-2 infection, using as a model SARS-CoV-2 Spike pseudotyped lentivirus (SARS-CoV-2 pseudovirus) and 293T cells transfected with human angiotensin-converting enzyme 2 (hACE2-293T cells). First, we determined the cytotoxicity of EEO and EOL using the MTT colorimetric assay, selecting non-cytotoxic concentrations ≤ 0.1% (v/v) for further analysis. Subsequently, we evaluated the capacity of EEO and EOL in cell cultures to preclude infection of hACE2-293T cells by SARS-CoV-2 pseudovirus, using a luciferase-based assay. We found that EEO and EOL significantly reduced SARS-CoV-2 pseudovirus infection, obtaining IC50 values of 0.00895% and 0.0042% (v/v), respectively. Likewise, EEO and EOL also reduced infection by vesicular stomatitis virus (VSV) pseudovirus, although higher concentrations were required. Hence, EEO and EOL may be able to inhibit SARS-CoV-2 infection, at least partially, through a Spike-independent pathway, supporting the implementation of aromatherapy with these agents as a cost-effective antiviral measure.

The effect of lavender and rosemary aromatherapy application on cognitive functions, anxiety, and sleep quality in the elderly with diabetes.

OBJECTIVE: This study aimed to determine the effects of aromatherapy use on cognitive function, anxiety, and sleep quality in the elderly with diabetes. METHODS: The study was conducted with 63 participants aged 65 and over. Participants were randomly divided into three groups: lavender, rosemary and control groups. The intervention continued for four weeks. Data was collected using the Blessed Orientation Concentration Test, State-Trait Anxiety Scale, and Pittsburgh Sleep Quality Scale. Data were analyzed using One-Way ANOVA, Mann-Whitney U/Kruskal-Wallis, Wilcoxon and Friedman tests. RESULTS: In both intervention groups, the 4th week scores of cognitive functions, anxiety, and sleep quality after aromatherapy were significant compared to the baseline scores. In the control group, state anxiety scores were significantly higher in the 2nd and 4th weeks compared to the initial scores. CONCLUSIONS: Inhaling lavender and rosemary has been observed to improve cognitive function and sleep quality and reduce anxiety levels. The effects of the essential oils used in the research were evaluated over four weeks. It is thought that studying for a longer period and with more samples would be beneficial. There is a need for studies examining its effects, especially in the elderly with diabetes.

Aromatherapy for the prevention of postoperative nausea and vomiting: A systematic review and meta-analysis.

Objectives: Postoperative nausea and vomiting (PONV) are common complications following surgical procedures. While drug-based treatments are standard, there is increasing interest in nonpharmacological alternatives, such as aromatherapy, due to potential benefits and minimal side effects. This study aimed to assess the effectiveness of aromatherapy in preventing PONV. Materials and Methods: A comprehensive systematic review and meta-analysis were conducted using PubMed, Cochrane Library, EMBASE, and CINAHL databases for studies published up to May 2023. The included studies were randomized controlled trials (RCTs) and nonrandomized studies of interventions that examined the impact of aromatherapy on PONV. The risk of bias was assessed, and the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was employed to evaluate the certainty of the evidence. Results: Eleven studies were selected for review, with eight RCTs included in the meta-analysis. Aromatherapy effectively reduced postoperative nausea severity (standardized mean difference [SMD]: -0.93, 95% confidence interval [CI]: -1.64 to -0.22; P = 0.010), but the reduction in vomiting episodes was not statistically significant (SMD: -0.81, 95% CI: -1.98-0.37; P = 0.180). Subgroup analysis indicated that ginger essence, lavender, and peppermint oils were particularly effective in managing postoperative nausea. However, due to significant statistical heterogeneity and potential biases in the studies, the results should be interpreted with caution. The certainty of the evidence, as evaluated by the GRADE approach, was low. Conclusion: Preliminary evidence supports the potential benefit of aromatherapy in reducing the severity of postoperative nausea. However, given the low certainty of current evidence, more rigorous and standardized research is needed. The safety, affordability, and potential benefits to patient comfort make aromatherapy a promising area for further research in postoperative care.

Effect of inhaled aromatherapy on sleep quality in critically ill patients: A systematic review and network meta-analysis.

AIM: This study aimed to compare the effect of inhaled aromatherapy using various essential oils on the sleep quality of critically ill patients. BACKGROUND: Inhalation of essential oils significantly promotes the physiological and psychological health of patients in intensive care units (ICUs). However, research identifying and ranking the effects of different essential oils on the sleep quality of critically ill patients is lacking. DESIGN: This study followed the PRISMA Extension Statement for Reporting of Systematic Reviews Incorporating Network Meta-Analyses of Health Care Interventions (PRISMA-NMA) guidelines. METHODS: A comprehensive search of five databases (Embase, MEDLINE, the Cochrane Library, CINAHL and PsycINFO) was conducted from their inception to March 15, 2023 (with an additional eligible study included dated August 14, 2023). Google Scholar was used as a supplementary method. Frequentist NMA was used to determine the effects of various essential oils. Certainty of evidence (CoE) was assessed using Confidence in Network Meta-Analysis (CINeMA). RESULTS: A total of 11 trials involving 690 critically ill patients were included in the analysis. The NMA of inhaled aromatherapy revealed that the combination of lavender, Matricaria recutita, and neroli essential oils (ratio 6:2:0.5) resulted in the most significant improvement in sleep quality compared to usual care, followed by Rosa damascene, peppermint, Citrus aurantium, pure sunflower oil and lavender oil alone.
