A preliminary randomized controlled trial of repetitive transcranial magnetic stimulation applied to the left dorsolateral prefrontal cortex in treatment seeking participants with cannabis use disorder.

BACKGROUND: Cannabis use disorder (CUD) is a common and consequential disorder. When applied to the dorsolateral prefrontal cortex (DLPFC), repetitive transcranial magnetic stimulation (rTMS) reduces craving across substance use disorders and may have therapeutic clinical effects when applied in serial-sessions. The present study sought to preliminarily determine whether serial-sessions of rTMS applied to the DLPFC had a therapeutic effect in CUD. METHODS: This study was a two-site, phase-2, double-blind, randomized-controlled-trial. Seventy-two treatment-seeking participants (37.5% Women, mean age 30.2±9.9SD) with ≥moderate-CUD were randomized to active or sham rTMS (Beam-F3, 10Hz, 20-total-sessions, two-sessions-per-visit, two-visits-per-week, with cannabis cues) while undergoing a three-session motivational enhancement therapy intervention. The primary outcome was the change in craving between pre- and post- treatment (Marijuana Craving Questionnaire Short-Form-MCQ-SF). Secondary outcomes included the number of weeks of abstinence and the number of days-per-week of cannabis use during 4-weeks of follow-up. RESULTS: There were no significant differences in craving between conditions. Participants who received active-rTMS reported numerically, but not significantly, more weeks of abstinence in the follow-up period than those who received sham-rTMS (15.5%-Active; 9.3%-Sham; rate ratio = 1.66 [95% CI: 0.84, 3.28]; p=0.14). Participants who received active-rTMS reported fewer days-per-week of cannabis use over the final two-weeks of the follow-up period than those receiving sham-rTMS (Active vs. Sham: -0.72; Z=-2.33, p=0.02). CONCLUSIONS: This trial suggests rTMS is safe and feasible in individuals with CUD and may have a therapeutic effect on frequency of cannabis use, though further study is needed with additional rTMS-sessions and a longer follow-up period.

Potential roles of circulating microRNAs in the healing of type 1 diabetic wounds treated with green tea extract: molecular and biochemical study.

Background: Circulating miRNAs have been implicated in various aspects of diabetic wound healing, including inflammation, angiogenesis, and extracellular matrix remodeling. Thus, in alternative herbal medicine strategies, miRNAs will be potential therapeutic molecular targets in nonhealing wounds. These could be valuable elements for understanding the molecular basis of diabetic wound healing and could be used as good elements in bioinformatics. Objectives: To elucidate the molecular mechanisms of microRNAs in association with apoptosis-inducing genes in controlling skin wound healing in diabetic wounds treated with green tea polyphenols (GTPs). Methods: Green tea hydro extract (GTE) at doses of100-200 mg/ml was topically applied to the skin tissues of rats with T1DM induced by a single dose of streptozotocin (STZ; 100 mg/kg, in 0.01 M sodium citrate, pH 4.3-4.5) injected intraperitoneally for seven consecutive days to induce T1DM. The rats were treated with green tea for three weeks. A sterile surgical blade was used to inflict a circular wound approximately 2 cm in diameter on the anterior-dorsal side of previously anesthetized rats by a combination of ketamine hydrochloride (50 mg/kg, i.e., body weight) and xylazine hydrochloride. Afterward, the molecular roles of the circulating miRNAs miR-21, miR-23a, miR-146a, and miR-29b and apoptotic genes were determined by quantitative real-time PCR to evaluate Bax, Caspase-3, and Bcl-2 in wound healing. In addition, HPLC analysis was also performed to estimate the active polyphenols (GTPs) present in the hydro extract of green tea leaves. Results: Wound healing was improved in diabetic skin wounds following treatment with GTE at doses of 100-200 mg/dl for three weeks. The wound parameters contraction, epithelialization, and scar formation significantly improved in a short time (14 days) compared to the longer periods identified in diabetic non-treated rats (20 days) and the standard control (15.5 days). Molecular analyses reported a significant increase in the levels of miR-21, miR-23a, and miR-146a and a decrease in the levels of miR-29b in green tea-treated diabetic rats compared to those in the standard control and STZ-diabetic non-treated rats. In addition, the molecular apoptotic genes Bax and caspase-3 significantly increased, and the BcL-2 gene significantly decreased following treatment with green tea polyphenols. Conclusions: The data showed that active green tea polyphenols (GTPs) present in GTE significantly improved diabetic wound healing by controlling apoptotic genes and the circulating microRNAs miR-21, miR-23a, miR-146a, and miR-29b, which might be involved in cellular apoptosis and angiogenesis processes. Thus, to establish a future model for the treatment of diabetic wounds, further studies are needed to understand the potential association of these biological parameters with the wound-healing process in diabetic wounds.

Exploring the impact of integrated polyvagal exercises and knee reinforcement in females with grade II knee osteoarthritis: a randomized controlled trial.

This study aimed to compare the effects of knee strengthening exercises to those of polyvagal theory-based exercises combined with knee strengthening exercises on selected outcomes in women with grade II knee osteoarthritis (OA). A randomized controlled trial was conducted, in which 60 female participants diagnosed with grade II knee OA, with a mean age of 57.27 ± 7.81 years and knee pain rated between 4 and 7 on the visual analog scale (VAS), were assigned to either the knee strengthening exercise group (Group 1, n = 30) or the polyvagal theory-based exercise plus knee strengthening exercise group (Group 2, n = 30). Pre- and posttreatment assessment of outcome variables, including WOMAC scores (joint pain, joint stiffness, functional limitations, and the overall index), WHOQOL scores (overall quality of life, general health, physical, psychological, social, and environmental domains), and heart rate variability (HRV, time and frequency domains), were analyzed. Group 2 demonstrated significantly greater reductions in joint pain, stiffness, and functional limitations than Group 1 after the intervention. Group 2 presented with significantly improved WOMAC scores, indicating better overall outcomes. Group 2 showed significant improvements in the psychological and social domains regarding quality of life. There were no significant differences in the physical domain or the environmental domain. Group 2 showed a significant increase in high-frequency power (HF) and a significant decrease in the LF/HF ratio, suggesting improved autonomic regulation. A combination of polyvagal exercise and knee strengthening training resulted in superior outcomes compared to knee strengthening exercises alone in women with grade II knee OA. These findings support the potential effectiveness of incorporating polyvagal exercises as an adjunctive intervention for osteoarthritis management.

Health status outcome among cannabis addicts after treatment of addiction.

The abuse of Cannabis is a widespread issue in the Asir region. It has a lot of legal and occupational repercussions. The purpose of this study was to evaluate the health status of cannabis addicts at admission and after treatment using body mass index, glycemic status, liver function, renal function, and oxidative stress. A cross-sectional study was conducted with 120 participants. The study was conducted at Al Amal Hospital for Mental Health in Asir region of Saudi Arabia, with 100 hospitalized patients receiving addiction treatment and 20 healthy volunteers. The participants were divided into two groups: group I, the control group, and group II, the cannabis addicts. The socio-demographic data were gathered. The level of cannabis in the urine and the CWAS [Cannabis Withdrawal Assessment Scale] were determined. In addition, the Body Mass Index [BMI], vital signs [temperature, heart rate, systolic blood pressure, diastolic blood pressure, and respiratory rate], serum levels of albumin, total bilirubin, direct bilirubin, AST, ALT, and ALP, urea, creatinine, Thiobarbituric acid-reactive substances [TBARS], superoxide dismutase [SOD], reduced glutathione [GSH], and catalase [CAT] were analyzed on the first day of admission and after treatment. According to the results, there was no significant change in the body mass index. The vital signs in the cannabis user group were significantly lower than the corresponding admission values. Regarding renal function tests such as urea and creatinine, we found that after treatment, the mean urea and creatinine values in the cannabis user group did not differ significantly from the corresponding admission values. However, after treatment, the mean values of fasting blood glucose levels in the cannabis user group were significantly lower than at admission. Also, the mean values of liver function tests such as albumin, total bilirubin, direct bilirubin, AST, ALT, and ALP in the cannabis user group were significantly lower than the corresponding admission values after treatment. In assessing the antioxidant system, we found that the mean values of TBARS, SOD, GSH, and CAT in the cannabis user group did not differ significantly from the corresponding admission values after treatment. The current findings have revealed that cannabis addiction harms the various body systems and has significant implications for the addict's state of health. The values of oxidative stress biomarkers did not change in this study, but other measured parameters improved after treatment.

Effect of slow breathing exercise and progressive muscle relaxation technique in the individual with essential hypertension: A randomized controlled trial.

PURPOSE: The present study aims to investigate the combined effect of slow breathing exercise (SBE) and progressive muscle relaxation (PMR) technique on blood pressure (BP), heart rate (HR), respiratory rate (RR), and anxiety in patients diagnosed with essential hypertension. TRIAL DESIGN: This study was based on a 4-arm parallel-group, randomized control design. METHODS: Sixty-four participants diagnosed with essential hypertension were randomly allocated into SBE, PMR, SBE-PMR, and Control groups, with 16 subjects each. All 3 groups received different treatments according to their name; however, the Control group received no treatment. Systolic and diastolic BP (SBP and DBP), HR, RR, and anxiety were all evaluated as the study outcomes using a digital sphygmomanometer and perceived stress scale (PSS) at baseline (pretest), 2nd week and 4th weeks post-intervention. A repeated measure analysis of variance test assessed intra-group comparison (overall) analyses across multiple time points. Bonferroni multiple comparison tests were used to analyze the mean differences between the groups. The confidence interval was kept at 95% for all the statistical analyses, that is, P < .05 is considered significant. RESULTS: There was a significant change in the HR (F = 239.04, P = .0001), RR (F = 167.74, P = .0001), SBP (F = 266.64, P = .0001), DSP (F = 279.80, P = .0001), and PSS (F = 473.42, P = .0001) as an outcome of baseline measurements versus (vs) the following weeks. There were significant (F = 48.57, P = .001) differences among different training on HR. The SBE vs SBE-PMR showed an insignificant difference (F = 48.54, P = 1.000). The RR showed significant differences (F = 32.05, 0.0001) between the SBE vs PMR, SBE vs Control, PMR vs Control, and SBE-PMR vs Control groups and insignificant differences for the SBE vs SBE-PMR and PMR vs SBE-PMR groups. The SBE vs SBE-PMR groups showed insignificant differences for DPP and SBP. However, PSS showed significant differences (F = 67.12, P = .0001) among the intervention groups except for the PMR and SBE-PMR groups. CONCLUSIONS: The combined interventions of SBEs and progressive muscle relaxation techniques can effectively reduce the heart rate, respiratory rate, BP, and anxiety in essential hypertensive patients compared to both techniques when given alone.

Nursing students perspectives of psychosocial care: cross-sectional study.

BACKGROUND: Psychosocial care is an integral component of holistic nursing practices. This study aimed to examine how fourth-year nursing students at Mutah University perceive various care characteristics, specifically psychosocial care. METHODS: A quantitative cross-sectional study was conducted using the Caring Dimension Inventory (CDI). Data were obtained from 105 nursing students before graduating from a Jordanian public educational institution. Data analyzed using the scoring of CDI and descriptive statistics. RESULTS: The mean scores in the professional and technical domain of care were statistically higher for fourth-year nursing students (4.69 ± 0.25). This exceeded their scores in the psychosocial domain of care (3.37 ± 1.20). This suggests that fourth-year nursing students prioritize professional and technical care over psychosocial care. CONCLUSIONS: Fourth-year nursing students tended to perceive the technical aspects of care as more significant than the psychosocial aspects. This highlights the need for nursing schools and healthcare providers to reconsider their focus and prioritize the importance of psychosocial care.

The Efficacy of Manual Therapy and Pressure Biofeedback-Guided Deep Cervical Flexor Muscle Strength Training on Pain and Functional Limitations in Individuals with Cervicogenic Headaches: A Randomized Comparative Study.

Objective: This study aimed to compare the efficacy of manual therapy and pressure biofeedback-guided DCFM strength training on pain intensity and functional limitations in individuals with CGH. Trial Design. A double-blinded, two-arm parallel group randomized comparative design. Methods: After applying the eligibility criteria, sixty out of eighty-nine CGH patients were recruited from King Saud University Medical Center in Riyadh and randomly allocated to intervention groups using simple random sampling. Group 1 underwent pressure biofeedback-guided DCFM strength training and conventional treatment, while Group 2 received manual therapy and conventional treatment for three consecutive weeks. The main outcome measures were scores on the visual analog scale (VAS) and the headache disability index (HDI). One assessor and two physical therapists were blinded to group allocation. Results: Sixty out of eighty participants aged 29-40 years were randomized into intervention groups (n = 30/group; age (mean ± standard deviation): group 1 = 35.0 ± 2.82; group 2 = 34.87 ± 2.60), and their data were analyzed. A significant improvement (95% CI, p < 0.05) was observed within each group when comparing the VAS and HDI scores between baseline and postintervention. In contrast, between-group comparisons for the outcome score of VAS and HDI revealed nonsignificant differences in the first, second, and third weeks after intervention, except for the VAS score, which showed a significant difference in weeks 2 and 3 after intervention. Cohen's d-value indicated that the intervention effect size for reducing pain was larger in group 1 than in group 2 at weeks 2 and 3. Conclusion: Compared with manual therapy, pressure biofeedback-guided DCFM strength training showed a greater reduction in pain intensity (assessed using the VAS) at weeks two and three. However, both treatments were equally effective in lowering headache-related functional limitations in patients with CGH. This trial is registered with ClinicalTrial.gov PRS (Identifier ID: NCT05692232).

Effectiveness of Aromatherapy in Early Palliative Care for Oncology Patients: Blind Controlled Study.

BACKGROUND: Palliative care is the active holistic treatment of people of all ages who have serious health-related suffering as a result of severe illness, and especially of those who are close to the end of life. Palliative care is provided to cancer patients who experience serious suffering that cannot be relieved without professional intervention and that compromises physical, social, spiritual, and emotional functioning. A straightforward, low-risk, and affordable palliative care approach may be provided through aromatherapy, a type of complementary and alternative medicine. The study objective is to assess the comparative effectiveness of massage, aromatherapy massage, and massage combined with aromatherapy inhalation on cancer patients receiving palliative care. METHODS: A total of 100 participants who were divided into four groups at random. The first group, designated as the control group, received standard hospital nursing care, the second group received massage only (using the odorless almond carrier oil), the third group received massage with lavender oil, and the fourth group received combined (inhalation and massage) aromatherapy. The Rotterdam Symptom Checklist (RSCL), given two weeks after aromatherapy, was used to examine participants' perspectives of care. RESULTS: On the RSCL, combined aromatherapy performed best. In terms of reported physical symptoms, psychological symptoms, and activities, there were statistically significant differences between the scores of the control group and each of the experimental groups. Nonetheless, the total quality of life score showed no significant difference between the control group and the massage only group (t = 0.529, p = 0.60). CONCLUSIONS: When paired with aromatherapy inhalation, massage has a positive effect on physical, psychological symptoms, activities, and overall quality of life for cancer patients receiving early palliative care. Nurses and other healthcare providers are recommended to support programs that provide message therapy to reduce reported bodily symptoms, psychological problems, and limited activities among cancer patients.

Effects of a program consisting of strain/counterstrain technique, phonophoresis, heat therapy, and stretching in patients with temporomandibular joint dysfunction: A pilot study.

BACKGROUND: The present study was conceptualized as a pilot study to examine the effects of a 3-week program consisting of strain/counterstrain technique (SCST), phonophoresis, heat therapy, and stretching exercises on pain and functions in patients with temporomandibular dysfunction (TMD). METHODS: Seven participants (mean age 25.85 years) diagnosed with TMD having pain in the temporomandibular joint (TMJ) area with decreased jaw opening were recruited for the study. Treatment interventions consisting of SCST, phonophoresis (ultrasound gel mixed with diclofenac gel), heat therapy, and stretching (mouth-opening) exercises were performed 3 days a week for 3 weeks. SCST was performed on the masseter, medial, and lateral pterygoid muscles. No control group was present in the study. RESULTS: Paired samples t test revealed a significant difference in numerical pain rating scale (NPRS) (decreased by 50%, P < .001) and jaw functional limitation scale (JFLS) (reduced by 59.58%, P < .001) scores after 3 weeks of intervention. A large effect size (Cohen d = -3.00 for NPRS and -3.16 for JFLS) was observed for both variables. No correlation (R = 0) was found between the baseline values of NPRS and JFLS. CONCLUSION: A 3-week program consisting of SCST, phonophoresis, heat therapy, and stretching exercises was effective in reducing the pain and improving the functions related to TMJ in patients suffering from TMD. However, a randomized controlled trial is needed to reach a definite conclusion.

A Preliminary Investigation Of Repetitive Transcranial Magnetic Stimulation Applied To The Left Dorsolateral Prefrontal Cortex In Treatment Seeking Participants With Cannabis Use Disorder.

Background: Cannabis use disorder (CUD) is a common and consequential disorder. When applied to the dorsolateral prefrontal cortex (DLPFC), repetitive transcranial magnetic stimulation (rTMS) reduces craving across substance use disorders and may have a therapeutic clinical effect when applied in serial sessions. The present study sought to preliminarily determine whether serial sessions of rTMS applied to the DLPFC had a therapeutic effect in CUD. Methods: This study was a two-site, phase-2, double-blind, randomized-controlled-trial. Seventy-two treatment-seeking participants (37.5% Women, mean age 30.2±9.9SD) with ≥moderate-CUD were randomized to active or sham rTMS (Beam-F3, 10Hz, 20-total-sessions, with cannabis cues) while undergoing a three-session motivational enhancement therapy intervention. The primary outcome was the change in craving between pre- and post-treatment (Marijuana Craving Questionnaire Short-Form-MCQ-SF). Secondary outcomes included the number of weeks of abstinence and the number of days-per-week of cannabis use during 4-weeks of follow-up. Results: There were no significant differences in craving between conditions. Participants who received active rTMS reported numerically, but not significantly, more weeks of abstinence in the follow-up period than those who received sham rTMS (15.5%-Active; 9.3%-Sham; rate ratio = 1.66 [95% CI: 0.84, 3.28]; p=0.14). Participants who received active rTMS reported fewer days-per-week of cannabis use over the final two-weeks of the follow-up period (Active vs. Sham: -0.72; Z=-2.33, p=0.02). Conclusions: This trial suggests rTMS is safe and feasible in individuals with CUD and may have a therapeutic effect on frequency of cannabis use, though further study is needed with additional rTMS-sessions and a longer follow-up period.

Cytotoxicity against A549 Human Lung Cancer Cell Line via the Mitochondrial Membrane Potential and Nuclear Condensation Effects of Nepeta paulsenii Briq., a Perennial Herb.

The genus Nepeta belongs to the largest Lamiaceae family, with 300 species, which are distributed throughout the various regions of Africa, Asia, India, and America. Along with other plant families distinguished by their medicinal and therapeutic values, the Nepeta genus of Lameaceae remains relatively valuable. Hence, the phytochemicals of N. paulsenii Briq. were extracted using different plant parts, i.e., leaves, stem, roots, flowers, and the whole plant by using various solvents (ethanol, water, and ethyl acetate), obtaining 15 fractions. Each extract of dried plant material was analyzed by FT-IR and GC-MS to identify the chemical constituents. The cytotoxicity of each fraction was analyzed by MTT assay and mitochondrial membrane potential and nuclear condensation assays against lung cancer cells. Among the ethyl acetate and ethanolic extracts, the flowers showed the best results, with IC50 values of 51.57 µg/mL and 50.58 µg/mL, respectively. In contrast, among the water extracts of the various plant segments, the stem showed the best results, with an IC50 value of 123.80 µg/mL. 5-flourouracil was used as the standard drug, providing an IC50 value of 83.62 µg/mL. The Hoechst 33342 stain results indicated apoptotic features, i.e., chromatin dissolution and broken down, fragmented, and crescent-shaped nuclei. The ethanolic extracts of the flowers showed more pronounced apoptotic effects on the cells. The mitochondrial membrane potential indicated that rhodamine 123 fluorescence signals suppressed mitochondrial potential due to the treatment with the extracts. Again, the apoptotic index of the ethanolic extract of the flowers remained the highest. Hence it can be concluded that the flower part of N. paulsenii Briq. was found to be the most active against the A459 human lung cancer cell line.

Determinants of quality of life of cancer patients at a tertiary care medical city in Riyadh, Saudi Arabia.

Background: Incidences of cancer are increasing at an unprecedented rate in Saudi Arabia, making it a major public health concern. Cancer patients are faced with physical, psychological, social, and economic challenges, all of which can impact quality of life (QoL). Objectives: This study aims to explore the sociodemographic, psychological, clinical, cultural, and personal factors that could affect the overall QoL of cancer patients. Methods: A total of 276 cancer patients who attended the King Saud University Medical City's oncology outpatient clinics between January 2018 to December 2019 were included. QoL was assessed with the Arabic version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30. Psychosocial factors were assessed with several validated scales. Results: QoL was poorer among patients who were female (p = 0.001), have visited a psychiatrist (p = 0.028); were taking psychiatric medications (p = 0.022); and had experienced anxiety (p < 0.001), depression (p < 0.001), and distress (p < 0.001). The most used method to self-treat was Islamic Ruqya (spiritual healing; 48.6%), and the most often perceived cause for developing cancer was evil eye or magic (28.6%). Good QoL outcomes were associated with biological treatment (p = 0.034) and satisfaction with health care (p = 0.001). A regression analysis showed that female sex, depression, and dissatisfaction with health care were independently associated with poor QoL. Conclusions: This study demonstrates that several factors could influence cancer patients' QoL. For instance, female sex, depression, and dissatisfaction with health care were all predictors of poor QoL. Our findings support the need for more programs and interventions to improve the social services for cancer patients, along with the need to explore the social difficulties oncology patients face and address such obstacles through improving social services by expanding the scope of social workers' contribution. Larger multicenter longitudinal studies are warranted to examine the generalizability of the results.

Effects of an incentive spirometer versus a threshold inspiratory muscle trainer on lung functions in Parkinson's disease patients: a randomized trial.

Upper airway obstruction, reduced maximal expiratory and inspiratory flows, reduced lung volumes, abnormal ventilatory control, and diaphragmatic dyskinesias are reported in patients with Parkinson's disease (PD). Inspiratory muscle training (IMT) has been reported to be effective in improving respiratory functions; however, no studies have compared the effects of the incentive spirometer (IS) with the threshold inspiratory muscle trainer (TIMT) in patients with PD. The study aimed to compare the effects of IS and TIMT on maximum inspiratory pressure (MIP), 6-min walk distance (6-MWD), forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and peak expiratory flow rate (PEFR) in patients with stage 1-3 according to the Hoehn and Yahr scale. 18 patients were randomly assigned to two groups, i.e., incentive spirometer (IS) and threshold inspiratory muscle trainer (TIMT) group. The IS group received IMT with volume-based IS, and the TIMT group received IMT with TIMT. MIP, 6-MWD, FVC, FEV1, and PEFR were measured before and after six weeks of training. In IS group: A significant increase (p < 0.05) was observed in MIP and 6-MWD by 18.13 and 5%, respectively. In the TIMT group: A significant increase (p < 0.05) was observed in MIP and 6-MWD by 30.15 and 8.94%, respectively. Both groups observed no significant difference (p > 0.05) in FVC, FEV1, and PEFR. When the two groups were compared, a greater increase (p < 0.05) was observed in the MIP and 6-MWD in the TIMT group compared to IS group. IMT with IS or TIMT for six weeks effectively increased MIP and 6-MWD in patients with stage 1-3 (Hoehn and Yahr scale) of PD. No improvement was observed in FVC, FEV1, or PEFR with any of the techniques. TIMT is more effective than IS in improving MIP and 6-MWD.

Real time patient-reported outcome measures in patients with cancer: Early experience within an integrated health system.

BACKGROUND: While patient-reported outcome measures (PROMs) have benefit in cancer clinical trials, real-world applications are lacking. This study describes the method of implementation of a cancer enterprise-wide PROMs platform. METHODS: After establishing a multispecialty stakeholder group within a large integrated health system, domain-specific instruments were selected from the National Institutes of Health's Patient-Reported Outcomes Measurement Information System (PROMIS) instruments (pain interference, fatigue, physical function, and depression) and were administered at varying frequencies throughout each patient's cancer journey. All cancer patients with an oncologic visit were eligible to complete the PROMs prior to the visit using a patient portal, or at the time of the visit using a tablet. PROMs were integrated into clinical workflow. Clinical partnerships were essential for successful implementation. Descriptive preliminary data were compared using multivariable logistic regression to determine the factors associated with method of PROMs completion. RESULTS: From September 16, 2020 to July 23, 2021, 23 of 38 clinical units (60.5%) implemented PROMs over 2392 encounters and 1666 patients. Approximately one third of patients (n = 629, 37.8%) used the patient portal. Black patients (aOR 0.70; 95% CI: 0.51-0.97) and patients residing in zip codes with higher percentage of unemployment (aOR: 0.07, 95% CI: 0.01-0.41) were among the least likely to complete PROMs using the patient portal. CONCLUSIONS: Successful system-wide implementation of PROMs among cancer patients requires engagement from multispecialty stakeholders and investment from clinical partners. Attention to the method of PROMs collection is required in order to reduce the potential for disparities, such as Black populations and those residing in areas with high levels of unemployment.

Effect of dentin biomodification using natural collagen cross-linkers on the durability of the resin-dentin bond and demineralized dentin stiffness.

OBJECTIVE: The purpose of this study was to evaluate the effect of using natural cross-linkers as sumac and curcumin on the durability of the resin-dentin bond and stiffness of demineralized dentin matrix. METHODS: Thirty sound molars were divided into 5 groups: Control (CO), Grape Seed extract (GSE), Cacao seed extract (CSE), Sumac extract (SE) and Curcumin extract (CE). The teeth had their coronal dentin exposed, etched, and pre-treated for 1 min with the extracts. Teeth were then bonded using Single-Bond II adhesive and 4 mm composite was built up on dentin surface. Teeth were sectioned into 1 × 1 × 8mm beams and their micro-tensile bond strength (µTBS) was tested after 24 h and 6 months of water storage. For stiffness testing, 15 teeth were sectioned to obtain dentin beams (1 × 1 × 6.5 mm), the beams were demineralized in 10% phosphoric acid then rinsed and divided into 5 groups. Beams were then immersed in their respective extract solution for 1 min after which they were subjected to a 3- point loading test using a universal testing machine to calculate their modulus of elasticity. RESULTS: After 24 h, no significant difference in µTBS was shown between all groups. After 6 Months, GSE, CE, and SE showed significantly higher µTBS compared to CO (p ≥ 0.05). For the modulus of elasticity; only GSE showed a significantly higher modulus compared to other groups. CLINICAL RELEVANCE: The application of grape seed extract, curcumin and sumac extract as dentin pre-treatments appear to be a promising approach to enhance the durability of the resin-dentin bond in a clinically relevant application time.

Antibacterial and antifungal activity of methanolic extracts of Salix alba L. against various disease causing pathogens / Atividade antibacteriana e antifúngica de extratos metanólicos de Salix alba L. contra vários patógenos que causam doenças

Abstract The present study was aimed to manifest the antibacterial and antifungal activity of methanolic extracts of Salix alba L. against seven Gram-positive and Gram-negative bacterial pathogens e.g. Streptococcus pyogenes, Staphylococcus aureus (1), S. aureus (2), Shigella sonnei, Escherichia coli (1), E. coli (2) and Neisseria gonorrhoeae and three fungal isolates from the air such as Aspergillus terreus, A. ornatus, and Rhizopus stolonifer. Two different serotypes of S. aureus and E. coli were used. The agar well-diffusion method results showed the dose-dependent response of plant extracts against bacterial and fungal strains while some organisms were found resistant e.g. E. coli (1), S. sonnei, A. terreus and R. stolonifer. The highest antibacterial activity was recorded at 17.000±1.732 mm from 100 mg/mL of leaves methanolic extracts against S. pyogenes while the activity of most of the pathogens decreased after 24 h of incubation. The highest antifungal activity was reported at 11.833±1.0 mm against A. ornatus at 50 mg/mL after 48 h of the incubation period. These experimental findings endorse the use of S. alba in ethnopharmacological formulations and suggest the use of methanolic extracts of the said plant to develop drugs to control the proliferation of resistant disease causing pathogenic microbes.

Resumo O presente estudo teve como objetivo manifestar a atividade antibacteriana e antifúngica de extratos metanólicos de Salix alba L. contra sete patógenos bacterianos Gram-positivos e Gram-negativos. Streptococcus pyogenes, Staphylococcus aureus (1), S. aureus (2), Shigella sonnei, Escherichia coli (1), E. coli (2) e Neisseria gonorrhoeae e três isolados de fungos do ar, como Aspergillus terreus, A. ornatus, e Rhizopus stolonifer. Dois sorotipos diferentes de S. aureus e E. coli foram usados. Os resultados do método de difusão em ágar mostraram a resposta dependente da dose de extratos de plantas contra cepas de bactérias e fungos, enquanto alguns organismos foram considerados resistentes, e.g. E. coli (1), S. sonnei, A. terreus e R. stolonifer. A maior atividade antibacteriana foi registrada em 17.000 ± 1.732 de 100 mg/mL de extratos metanólicos de folhas contra S. pyogenes, enquanto a atividade da maioria dos patógenos diminuiu após 24 h de incubação. A maior atividade antifúngica foi relatada em 11,833 ± 1,0 contra A. ornatus a 50 mg/mL após 48 h do período de incubação. Esses achados experimentais endossam o uso de S. alba em formulações etnofarmacológicas e sugerem o uso de extratos metanólicos da referida planta para o desenvolvimento de fármacos que controlem a proliferação de doenças resistentes que causam micróbios patogênicos.

Antibacterial and antifungal activity of methanolic extracts of Salix alba L. against various disease causing pathogens

Abstract The present study was aimed to manifest the antibacterial and antifungal activity of methanolic extracts of Salix alba L. against seven Gram-positive and Gram-negative bacterial pathogens e.g. Streptococcus pyogenes, Staphylococcus aureus (1), S. aureus (2), Shigella sonnei, Escherichia coli (1), E. coli (2) and Neisseria gonorrhoeae and three fungal isolates from the air such as Aspergillus terreus, A. ornatus, and Rhizopus stolonifer. Two different serotypes of S. aureus and E. coli were used. The agar well-diffusion method results showed the dose-dependent response of plant extracts against bacterial and fungal strains while some organisms were found resistant e.g. E. coli (1), S. sonnei, A. terreus and R. stolonifer. The highest antibacterial activity was recorded at 17.000±1.732 mm from 100 mg/mL of leaves methanolic extracts against S. pyogenes while the activity of most of the pathogens decreased after 24 h of incubation. The highest antifungal activity was reported at 11.833±1.0 mm against A. ornatus at 50 mg/mL after 48 h of the incubation period. These experimental findings endorse the use of S. alba in ethnopharmacological formulations and suggest the use of methanolic extracts of the said plant to develop drugs to control the proliferation of resistant disease causing pathogenic microbes.

Resumo O presente estudo teve como objetivo manifestar a atividade antibacteriana e antifúngica de extratos metanólicos de Salix alba L. contra sete patógenos bacterianos Gram-positivos e Gram-negativos. Streptococcus pyogenes, Staphylococcus aureus (1), S. aureus (2), Shigella sonnei, Escherichia coli (1), E. coli (2) e Neisseria gonorrhoeae e três isolados de fungos do ar, como Aspergillus terreus, A. ornatus, e Rhizopus stolonifer. Dois sorotipos diferentes de S. aureus e E. coli foram usados. Os resultados do método de difusão em ágar mostraram a resposta dependente da dose de extratos de plantas contra cepas de bactérias e fungos, enquanto alguns organismos foram considerados resistentes, e.g. E. coli (1), S. sonnei, A. terreus e R. stolonifer. A maior atividade antibacteriana foi registrada em 17.000 ± 1.732 de 100 mg/mL de extratos metanólicos de folhas contra S. pyogenes, enquanto a atividade da maioria dos patógenos diminuiu após 24 h de incubação. A maior atividade antifúngica foi relatada em 11,833 ± 1,0 contra A. ornatus a 50 mg/mL após 48 h do período de incubação. Esses achados experimentais endossam o uso de S. alba em formulações etnofarmacológicas e sugerem o uso de extratos metanólicos da referida planta para o desenvolvimento de fármacos que controlem a proliferação de doenças resistentes que causam micróbios patogênicos.

Knowledge, attitude and dispensing practice of the pharmacists related to complementary alternative medicines in the Riyadh region of Saudi Arabia: a cross-sectional descriptive study.

BACKGROUND: The use of complementary alternative medicines (CAMs) has risen globally in recent times. Such medications are exclusively and readily available in the Riyadh region of Saudi Arabia through community pharmacies and other retail outlets, exposing the consumers to various risks like harmful drug interactions. These situations take pharmacists to a responsible position where they should provide evidence-based information to help consumers make safe consumption. The consumption of CAMs can be ensured safe if pharmacists have appropriate knowledge and training about their use, dosing, side effects, etc. This study aimed to investigate and evaluate the pharmacist's factual knowledge, perception and dispensing practice related to various aspects of CAMs based on gender and experience. METHODS: The study followed a structured self-administered questionnaire-based cross-sectional survey design. Out of 200, with a response rate of 89.5%, 179 pharmacists (115 males; 64 females) from the Riyadh region of Saudi Arabia participated in this study. The knowledge scores of male and female pharmacists were compared using an unpaired t-test. The correlation between pharmacists' knowledge and their work experience was determined using Pearson's correlation coefficient test, keeping the significance value at p < 0.05. RESULTS: Almost all the respondents (99%) reported that they had never attended any lecture or course related to CAMs. Results show low knowledge scores, indicating poor respondents' knowledge concerning the use of CAMs. No significant difference was observed in knowledge scores based on gender, and no significant correlation between pharmacists' knowledge scores and their work experiences. CONCLUSION: Therefore, the study concluded that both male and female pharmacists possess equal knowledge concerning the use of CAMs, and their work experience doesn't differentiate in their knowledge. Various factors like lack of time, etc., prevented respondents from interacting with patients. Regular organization of mandatory continuing education programs about the safe use of CAMs that can improve their knowledge is recommended. In addition, establishing a pharmacy connection network system can enhance patient monitoring and CAMs vigilance. This study lays a foundation for further work to assess pharmacists' knowledge and practice patterns in Saudi Arabia. TRIAL REGISTRATION: Not applicable.

The association of mindfulness with professional quality of life and negative emotional states among critical care nurses during COVID-19 pandemic.

BACKGROUND: The recent coronavirus disease 2019 (COVID-19) pandemic has imposed severe psychological pressure on nurses. Mindfulness has been shown to be effective in improving professional quality of life (ProQOL) and reducing psychological distress in a wide range of populations and contexts. However, its role in supporting critical care nurses during the outbreak of COVID-19 has yet to be established. PURPOSE: This study explores the relationship of mindfulness with negative emotional states and ProQOL among nurses working in critical care units during COVID-19 pandemic. METHODS: A cross-sectional descriptive correlational design was used. A sample of 156 critical care nurses completed self-reported measures of mindfulness, ProQOL, and negative emotional states. Multiple regressions were used to address the study purpose. RESULTS: Overall, the participants had severe anxiety, moderate depression, moderate stress, moderate burnout, moderate secondary traumatic stress, and moderate compassion satisfaction. Mindfulness was significantly and negatively associated with stress (r = - 0.230, p = .004), depression (r = - 0.190, p = .018), burnout (r = - 0.218, p = .007), and secondary traumatic stress (r = - 0.168, p = .037). Mindfulness explained 3% of the variance in depression (B = -0.19, p = .018), 3.9% of variance in stress, (B = -0.201, p = .012), 4.2% of variance in BO (B = -0.206, p = .009), and 2.2% of the variance in secondary traumatic stress (B = -0.168, t = -2.104, p = .037), controlling for demographics. CONCLUSIONS: The current study provides preliminary evidence that mindfulness can be helpful in reducing critical care nurses' psychological distress and promoting their ProQOL, and is worthy of further investigation in this population.

Effects of myofascial release with tennis ball on spasticity and motor functions of upper limb in patients with chronic stroke: A randomized controlled trial.

BACKGROUND: Impaired motor function and upper extremity spasticity are common concerns in patients after stroke. It is essential to plan therapeutic techniques to recover from the stroke. The objective of this study was to investigate the effects of myofascial release with the tennis ball on spasticity and motor functions of the upper extremity in patients with chronic stroke. METHODS: Twenty-two chronic stroke patients (male-16, female-6) were selected to conduct this study. Two groups were formed: the control group (n=11) which included conventional physiotherapy only and the experimental group (n=11) which included conventional physiotherapy along with tennis ball myofascial release - in both groups interventions were performed for 6 sessions (35 minutes/session) per week for a total of 4 weeks. The conventional physiotherapy program consisted of active and passive ROM exercises, positional stretch exercises, resistance strength training, postural control exercises, and exercises to improve lower limb functions. All patients were evaluated with a modified Ashworth scale for spasticity of upper limb muscles (biceps brachii, pronator teres, and the long finger flexors) and a Fugl-Meyer assessment scale for upper limb motor functions before and after 4 weeks. Nonparametric (Mann-Whitney U test and Wilcoxon signed-rank test) tests were used to analyze data statistically. This study has been registered on clinicaltrial.gov (ID: NCT05242679). RESULTS: A significant improvement (P < .05) was observed in the spasticity of all 3 muscles in both groups. For upper limb motor functions, significant improvement (P < .05) was observed in the experimental group only. When both groups were compared, greater improvement (P < .05) was observed in the experimental group in comparison to the control group for both spasticity of muscles and upper limb motor functions. CONCLUSION: Myofascial release performed with a tennis ball in conjunction with conventional physiotherapy has more beneficial effects on spasticity and motor functions of the upper extremity in patients with chronic stroke compared to conventional therapy alone.
