Randomized Controlled Trial Comparative Study
A Randomized Single-Blinded Phase II Trial Comparing Efficacy and Quality of Life of Topical Aloe Vera Gel Plus Urea Cream Versus Urea Cream Alone for Prevention of Hand Foot Syndrome in Cancer Patients Receiving Capecitabine.
INTRODUCTION
Capecitabine has been widely prescribed to treat various cancers. The hand foot syndrome (HFS) is the most troublesome adverse effect. Urea cream has been pre-emptively co-prescribed, even though its efficacy is doubtful. Aloe vera gel with urea cream might potentiate each other. This trial was intended to prove the efficacy of this combination.
MATERIALS AND METHODS
The investigators conducted a randomized single-blinded phase II study. The participants were randomized 1:1 to receive the combination of aloe vera gel and 10% urea cream (n = 30), the experimental A+U arm and 10% urea cream alone (n = 31), the U arm. The sample size was calculated to have 90% power to show the significant 20% reduction in the incidence of HFS grade 2-3 of the combination therapy with alpha level = 0.05. Both the CTCAE criteria version 5 and the dermatology life quality index (DLQI) were assessed to determine the severity of HFS and quality of life, respectively.
RESULTS
Most of the participants had rectal cancer (A+U: 43.3%; U: 41.9%). In the A+U group, 86.7% had grade 0-1 HFS and 13.3% had grade 2-3 HFS. In the U group, 64.5% had grade 0-1 HFS and 35.5% had grade 2-3 HFS (Mann-Whitney U test, p = 0.045). Grade 2-3 HFS was significantly lower in the combination group.
CONCLUSION
Combination of aloe vera gel and 10% urea cream ameliorated the severity of HFS in participants taking capecitabine; however, no significant difference in DLQI between the groups was demonstrated.

Randomized Controlled Trial
IMPORTANCE
Fentanyl has exacerbated the opioid use disorder (OUD) and opioid overdose epidemic. Data on the effectiveness of medications for OUD among patients using fentanyl are limited.
OBJECTIVE
To assess the effectiveness of sublingual or extended-release injection formulations of buprenorphine for the treatment of OUD among patients with and without fentanyl use.
DESIGN, SETTING, AND PARTICIPANTS
Post hoc analysis of a 24-week, randomized, double-blind clinical trial conducted at 35 outpatient sites in the US from December 2015 to November 2016 of sublingual buprenorphine-naloxone vs extended-release subcutaneous injection buprenorphine (CAM2038) for patients with OUD subgrouped by presence vs absence of fentanyl or norfentanyl in urine at baseline. Study visits with urine testing occurred weekly for 12 weeks, then 6 times between weeks 13 and 24. Data were analyzed on an intention-to-treat basis from March 2022 to August 2023.
INTERVENTION
Weekly and monthly subcutaneous buprenorphine vs daily sublingual buprenorphine-naloxone.
MAIN OUTCOMES AND MEASURES
Retention in treatment, percentage of urine samples negative for any opioids (missing values imputed as positive), percentage of urine samples negative for fentanyl or norfentanyl (missing values not imputed), and scores on opiate withdrawal scales and visual analog craving scales.
RESULTS
Of 428 participants, 123 (subcutaneous buprenorphine, n = 64; sublingual buprenorphine-naloxone, n = 59; mean [SD] age, 39.1 [10.8] years; 75 men [61.0%]) had evidence of baseline fentanyl use and 305 (subcutaneous buprenorphine, n = 149; buprenorphine-naloxone, n = 156; mean [SD] age, 38.1 [11.1] years; 188 men [61.6%]) did not have evidence of baseline fentanyl use. Study completion was similar between the fentanyl-positive (60.2% [74 of 123]) and fentanyl-negative (56.7% [173 of 305]) subgroups. The mean percentage of urine samples negative for any opioid were 28.5% among those receiving subcutaneous buprenorphine and 18.8% among those receiving buprenorphine-naloxone in the fentanyl-positive subgroup (difference, 9.6%; 95% CI, -3.0% to 22.3%) and 36.7% among those receiving subcutaneous buprenorphine and 30.6% among those receiving buprenorphine-naloxone in the fentanyl-negative subgroup (difference, 6.1%; 95% CI, -1.9% to 14.1%), with significant main associations of baseline fentanyl status and treatment group. In the fentanyl-positive subgroup, the mean percentage of urine samples negative for fentanyl during the study was 74.6% among those receiving subcutaneous buprenorphine vs 61.9% among those receiving sublingual buprenorphine-naloxone (difference, 12.7%; 95% CI, 9.6%-15.9%). Opioid withdrawal and craving scores decreased rapidly after treatment initiation across all groups.
CONCLUSIONS AND RELEVANCE
In this post hoc analysis of a randomized clinical trial of sublingual vs extended-release injection buprenorphine for OUD, buprenorphine appeared to be effective among patients with baseline fentanyl use. Patients with fentanyl use had fewer opioid-negative urine samples during the trial compared with the fentanyl-negative subgroup. These findings suggest that the subcutaneous buprenorphine formulation may be more effective at reducing fentanyl use.

Comparative Study
This retrospective study investigates the efficacy of 2 treatment regimens, pregabalin alone versus pregabalin combined with ketamine, amitriptyline, and lidocaine cream, in reducing itch in patients with brachioradial pruritus at a tertiary care center. Electronic medical records of 64 brachioradial pruritus patients seen at the University of Miami Itch Center were analyzed. A significant reduction in itch scores was seen with both treatments, with no significant difference between the groups. A small number of patients experienced adverse effects, including drowsiness and weight gain with pregabalin and skin irritation with ketamine, amitriptyline, and lidocaine cream. Ultimately, our findings underscore the potential of utilizing combined therapy for difficult-to-treat brachioradial pruritus cases and implementing individualized approaches for managing neuropathic pruritus. Further controlled clinical trials are needed to establish optimal treatment protocols.

PURPOSE
SN-38 (7-ethyl-10-hydroxycamptothecin), the active metabolite of irinotecan, has been extensively studied in drug delivery systems. However, its impact on neural metabolism remains unclear. This study aims to investigate the toxic effects of SN-38 on mouse brain metabolism.
METHODS
Male mice were divided into an SN-38 group and a control group. The SN-38 group received SN-38 (20 mg/kg/day) via intraperitoneal injection, while the control group was given an equal volume of a blank solvent mixture (DMSO and saline, ratio 1:9). Gas chromatography-mass spectrometry (GC-MS) was employed to analyze differential metabolites in the cortical and hippocampal regions of the SN-38-treated mice.
RESULTS
SN-38 induced metabolic disturbances in the central nervous system. Eighteen differential metabolites were identified in the hippocampus and twenty-four in the cortex, with six common to both regions. KEGG pathway enrichment analysis revealed statistically significant alterations in six metabolic pathways in the hippocampus and ten in the cortex (P<0.05).
CONCLUSION
This study is the first to demonstrate the neurotoxicity of SN-38 in male mice through metabolomics. Differential metabolites in the hippocampal and cortical regions were closely linked to purine metabolism, pyrimidine metabolism, amino acid metabolism, and glyceride metabolism, indicating disruptions in the blood-brain barrier, energy metabolism, and central signaling pathways.

PeerJ 2024To evaluate the efficacy and safety of Brolucizumab for neovascular age-related macular degeneration (n-AMD) through a systematic review and meta-analysis. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
To evaluate the efficacy and safety of Brolucizumab for neovascular age-related macular degeneration (n-AMD) through a systematic review and meta-analysis.
MATERIALS AND METHODS
Cochrane, PubMed, Embase, and Web of Science databases were comprehensively searched for relevant studies. Stata and RevMan5.4 were applied for meta-analysis and risk of bias assessment. Data on the best-corrected visual acuity (BCVA), central subfield thickness (CSFT), presence of intraretinal fluid (IRF) and/or subretinal fluid (SRF), participants with ≥1 serious adverse events, and participants with ≥1 adverse events were analyzed.
RESULTS
Six studies were finally included. Meta-analysis showed statistical differences in BCVA [SMD = -0.65, 95% CI [-0.17 to -0.23], < 0.05], the presence of IRF and/or SRF [RR = 0.67, 95% CI [0.56-0.79], < 0.05], and the safety of participants with ≥1 serious adverse events [RR = 0.57, 95% CI [0.39-0.84], < 0.05] between the experimental group and the control group. However, no statistical differences were observed in CSFT [SMD = -1.16, 95% CI [-2.79 to 0.47], > 0.05] or the safety of participants with ≥1 adverse events [RR = 1.07, 95% CI [0.97-1.17], > 0.05].
CONCLUSIONS
Compared to other anti-VEGF drugs such as Aflibercept and Ranibizumab, intravitreal injection of 6 mg Brolucizumab is more effective and safer for n-AMD, especially in the presence of IRF and/or SRF, and for participants with ≥1 serious adverse events.

BACKGROUND
Mediterranean diet rich in polyphenolic compounds holds great promise to prevent and alleviate multiple sclerosis (MS), a central nervous system autoimmune disease associated with gut microbiome dysbiosis. Health-promoting effects of natural polyphenols with low bioavailability could be attributed to gut microbiota reconstruction. However, its underlying mechanism of action remains elusive, resulting in rare therapies have proposed for polyphenol-targeted modulation of gut microbiota for the treatment of MS.
RESULTS
We found that oral ellagic acid (EA), a natural polyphenol rich in the Mediterranean diet, effectively halted the progression of experimental autoimmune encephalomyelitis (EAE), the animal model of MS, via regulating a microbiota-metabolites-immunity axis. EA remodeled the gut microbiome composition and particularly increased the relative abundances of short-chain fatty acids -producing bacteria like Alloprevotella. Propionate (C3) was most significantly up-regulated by EA, and integrative modeling revealed a strong negative correlation between Alloprevotella or C3 and the pathological symptoms of EAE. Gut microbiota depletion negated the alleviating effects of EA on EAE, whereas oral administration of Alloprevotella rava mimicked the beneficial effects of EA on EAE. Moreover, EA directly promoted Alloprevotella rava (DSM 22548) growth and C3 production in vitro. The cell-free supernatants of Alloprevotella rava co-culture with EA suppressed Th17 differentiation by modulating acetylation in cell models. C3 can alleviate EAE development, and the mechanism may be through inhibiting HDAC activity and up-regulating acetylation thereby reducing inflammatory cytokines secreted by pathogenic Th17 cells.
CONCLUSIONS
Our study identifies EA as a novel and potentially effective prebiotic for improving MS and other autoimmune diseases via the microbiota-metabolites-immunity axis. Video Abstract.

Randomized Controlled Trial
INTRODUCTION
Even after the peak of the COVID-19 pandemic, the number of mild cases remains high, requiring continuous control. Curcumin, owing to its anti-inflammatory properties, can suppress vital proliferation and cytokine secretion in animal models. We developed a highly absorbable curcumin, curcuRouge (cR), which is approximately 100 times more orally bioavailable than conventional curcumin. We evaluated the effect of cR on the inhibition of disease progression in asymptomatic or mildly symptomatic COVID-19 patients.
METHODS
This study evaluated the effect of 7-day oral intake of cR (360 mg twice daily). Patients within 5 days of COVID-19 diagnosis were randomly assigned to a placebo or cR group in a double-blind manner.
RESULTS
Primary endpoint events [body temperature (BT) ≥ 37.5 °C and saturation of percutaneous oxygen (SpO2) < 96%] were fewer than expected, and the rate of these events was 2.8% in the cR group (2/71) and 6.0% in the placebo group (4/67); hazard ratio (HR) = 0.532, 95% confidence interval (CI) 0.097-2.902. Patients receiving cR tended to take fewer antipyretic medications than those receiving placebo (HR = 0.716, 95% CI 0.374-1.372). Among patients with a normal range of BT at baseline, the BT change rate was significantly (p = 0.014) lower in the cR group (- 0.34%) versus placebo (- 0.01%).
CONCLUSION
The relative suppression of event rates and antipyretic medications taken, and significant decrease of subclinical BT support the anti-inflammatory effects of cR in asymptomatic or mildly symptomatic patients with COVID-19.

Randomized Controlled Trial
The present study aimed to assess the effectiveness and functional adverse effects of a single and multiple injections of botulinum toxin A (BoNT-A) for masseter hypertrophy (MH). Twenty-six women complaining about lower third facial enlargement due to MH, received 75 U of BoNT-A (abobotulinum toxin) in each masseter muscles. After 3 months, patients were randomly assigned to receive a second treatment session of Saline Solution: (G1; n = 11) or BoNT-A: (G2; n = 12). Muscle thickness (ultrasound), electrical activity (electromyography; EMG), masticatory performance, and subjective perception of MH were evaluated. Follow-up was performed at 1, 3 and 6 months. Muscle thickness, EMG activity, and masticatory performance were analyzed using ANOVA two-way and Sidak test as post-hoc. Masticatory performance was analyzed by the Friedman's test and Mann-Whitney test. Regarding inter-groups comparisons, there was a significant decrease in the left masseter muscle thickness in the G2 group at the 6 month follow-up (p < 0.02). For EMG, significant differences were evident at the 6 month assessment, with higher masseter activity for G1 (p < 0.05). For masticatory performance, no significant differences were observed throughout the study (p > 0.05) and a higher improvement in subjective perception of MH was observed in the 1 month follow-up for G2 (p < 0.05). In conclusion, BoNT-A is effective for MH, however multiple injections cause functional adverse effects in masseter muscle.

Gynecological Endocrinology : the... Dec 2024Female sexual interest and arousal disorder (FSIAD) is the most prevalent female sexual dysfunction in the postmenopause. (Review)
Review
INTRODUCTION
Female sexual interest and arousal disorder (FSIAD) is the most prevalent female sexual dysfunction in the postmenopause.
OBJECTIVE
The aim of this review is to provide a summary of the currently available evidence on the use of testosterone in the treatment of FSIAD in postmenopausal women.
METHODS
A narrative review on the topic was performed. Only randomized controlled trials (RCTs) and systematic reviews and meta-analysis were considered. 123 articles were screened, 105 of them assessed for eligibility, and finally 9 were included in qualitative synthesis following the PRISMA declaration.
RESULTS
Current evidence recommends, with moderate therapeutic benefit, the use of systemic transdermal testosterone within the premenopausal physiological range in postmenopausal women with Hypoactive Sexual Desire Disorder (HSDD), the previous entity for low desire dysfunction, not primarily related to modifiable factors or comorbidities such as relationship or mental health problems. The available evidence is based on studies with heterogeneity on their design (different testosterone doses, routes of administration, testosterone use in combination and alone, sexual instruments of measurement). There is no data indicating severe short-term adverse effects, although long-term safety data is lacking.
CONCLUSIONS
Despite having testosterone as a valuable tool, therapeutic strategies are lacking in the pharmacological field of HSDD/FSIAD. Neuroimaging studies could provide valuable information regarding the sexual desire substrate and suggest the potential application of already approved drugs for women with a good safety profile. The use of validated instruments for HSDD in postmenopausal women, considering the level of distress, is necessary to be able to draw robust conclusions on the evaluated treatments.
