Ductal lavage followed by observation versus oral corticosteroids in idiopathic granulomatous mastitis: A randomized trial

Oral corticosteroids represents the most prevalent treatment for idiopathic granulomatous mastitis. Ductal lavage with triamcinolone acetonide and antibiotics followed by observation (DL-OBS) has emerged as a novel strategy, but a comparison of them remains lacking. Here in this multicenter, open-label, non-inferiority, randomized trial (ClinicalTrials.gov identifier: NCT03724903), we assigned 140 patients to oral corticosteroids (N = 71) and DL-OBS (N = 69), stratified by baseline M-score. The primary outcome is complete Clinical Response rate at 1 year. The non-inferiority margin is −15%. The primary outcome is 85.5% in DL-OBS and 87.3% in oral corticosteroids (difference: −1.8%; 95%CI, 13.2 to 9.5; Pnon-inferiority = .01) in intention-to-treat population, and 92.6% vs 98.2% (difference −5.6%; 95%CI −13.4 to 2.2; Pnon-inferiority = .01) in per-protocol population, respectively. The most common (>15%) adverse events were Cushingoid, epigastric pain and arthralgia in oral corticosteroids, and irregular menstruation in DL-OBS, respectively. Here, we report that DL-OBS shows similar efficacy to oral corticosteroids but with better safety profile.

Postoperative quality of recovery comparison between ciprofol and propofol in total intravenous anesthesia for elderly patients undergoing laparoscopic major abdominal surgery: A randomized, controlled, double-blind, non-inferiority trial

Study objectivesWe conducted a non-inferiority study to assess the postoperative quality of recovery (QoR) in elderly patients receiving ciprofol or propofol total intravenous anesthersia(TIVA)after elective laparoscopic major abdominal surgery, with QoR-15 scores as the main measure. DesignA prospective, double-blind, randomized non-inferiority trial was conducted in the theater, post-anesthesia care unit (PACU), and the ward. Participants144 elderly patients (age ≥ 65 years) were randomly assigned to either the ciprofol group or the propofol group. InterventionsThe ciprofol group received continuous infusion of ciprofol with remifentanil, and the propofol group received infusion of propofol with remifentanil. Outcome measuresThe primary outcome was the QoR-15 on the first postoperative day (POD1), assessed in both intention-to-treat and per-protocol populations, with the mean difference between groups compared to a non-inferiority threshold of −8. Additional assessments included QoR-15 scores on POD2, 3, and 5 for both analysis sets. Other evaluated perioperative value factors included hemodynamic parameters and injection discomfort in the intention-to-treat analysis. A linear mixed model was utilized to examine the impact of group-time interactions on hemodynamic data and QoR-15. Main resultsThe QoR-15 scores on POD1 in the ciprofol group were non-inferior to those in the propofol group both in intention-to-treat set (mean [95 %CI], 95.9[93.7–98.2] vs. 95.6 [93.3–97.8]; mean difference [95 % CI], 0.4 [−2.8–3.5]; P<0.001 for noninferiority) and per-protocol set (mean [95 %CI], 96.7 [94.4–99.0] vs. 95.7 [93.4–98.0]; mean difference [95 % CI], 1.0 [−2.2–4.3]; P<0.001 for noninferiority). Comparable outcomes were noted on postoperative days 2, 3, and 5 following the procedure in both analysis sets. Additionally: compared with propofol group, the occurrence of injection pain was lower (2.8 % vs. 27.8 %, P < 0.001); the hypotension was less frequent (33.3 % vs. 54.2 %, P = 0.012); the bradycardia was more common (38.9 % vs. 23.6 %, P = 0.048). ConclusionsCiprofol is not inferior to propofol in QoR. Ciprofol can be suitably administered to elderly patients undergoing elective laparoscopic major abdominal surgery.

Efficacy and safety of a lipid-containing artificial tear compared with a non-lipid containing tear: a randomized clinical trial.

Dry eye disease (DED) is a prevalent condition affecting over 16 million patients in the USA. DED and the symptoms of ocular discomfort are debilitating and a significant burden on patients. If left untreated, DED can progress to cause severe pathology. Treatment is often initiated by patients without consulting a healthcare professional. This study investigated the safety and efficacy of a novel lipid-containing eye drop (BTC), which might better mimic the components of natural tears. This was a multicenter, randomized, double-masked, active control, two arm, parallel group study of eye drops in adult subjects with self-reported DED. Subjects were randomly assigned to BTC or control (commercially available non-lipid eye drops; NLED) arm and were followed for 30 days. Assessments using visual analog scale and patient-reported outcomes (PRO) questionnaires, non-invasive tear break up time, slit-lamp examination, and subject-reported ocular symptoms were conducted at baseline and at days 7 and 30. The primary endpoint was change in overall ocular comfort score from baseline to day 30. 158 subjects were randomized, of whom 130 completed the study per protocol (PP). Mean (SD) age was 47.8 (14.14) years. The mean (95% CI) change in overall comfort scores at the 30-day follow-up in the PP population was 21.4 (15.1, 27.7) for the test drop and 10.0 (3.9, 16.1) for the comparator. The mean (95% CI) treatment difference was 11.3 (2.6, 20.1); this met the pre-defined requirements for non-inferiority. There was no significant difference in the proportion of eyes with reported ocular symptoms between the groups. At day 7, the OR (95% CI) was 0.967 (0.528, 1.770) and at day 30 was 1.160 (0.610, 2.203). There were no Grade 3 or higher corneal edema, corneal neovascularization, corneal staining, conjunctival injection, tarsal abnormalities or any other biomicroscopy findings, and no corneal infiltrates observed during the study. The investigational lipid eye drop BTC was noninferior to the commercially available non-lipid comparator in all parameters measured and has the potential to provide an effective therapy for subjects with symptoms of dry eye who would benefit from a lipid-based artificial tear.

Estetrol Inhibits the Prostate Cancer Tumor Stimulators FSH and IGF-1

Background: The co-treatment of androgen deprivation therapy (ADT) for advanced prostate cancer (PCa) with the fetal estrogen estetrol (E4) may further inhibit endocrine PCa tumor stimulators. We previously reported the suppression of follicle-stimulating hormone (FSH), total and free testosterone, and prostate-specific antigen by ADT+E4. Here, we provide more detailed data on FSH suppression by E4 and present new findings on the effect of ADT+E4 on insulin-like growth factor-1 (IGF-1). Methods: A Phase II, double-blind, randomized, placebo-controlled study (the PCombi study) was conducted in advanced PCa patients treated with ADT. The study assessed the effect of E4 co-treatment with LHRH agonist ADT on tumor stimulators, including FSH and IGF-1. Patients starting ADT were randomized 2:1 to receive either 40 mg E4 (n = 41) or placebo (n = 21) for 24 weeks. Non-parametric analyses were performed on the per-protocol population (PP) and individual changes were visualized. Results: The PP included 57 patients (37 ADT+E4; 20 ADT+placebo). ADT+E4 almost completely suppressed FSH in all patients (98% versus 37%; p &lt; 0.0001). IGF-1 levels decreased by 41% with ADT+E4 versus an increase of 10% with ADT+placebo (p &lt; 0.0001). Conclusions: The almost complete suppression of the tumor stimulator FSH using ADT plus E4 observed in all individual patients in this study, along with the augmented suppression of IGF-1 versus an increase by ADT only, may be clinically relevant and suggest the enhanced anti-cancer treatment efficacy of E4 in addition to the previously reported additional suppression of total and free T and PSA.

Ultrasound-guided superficial cervical plexus blocks for persistent pain after suboccipital craniotomies: a randomized trial.

The efficacy of superficial cervical plexus blocks for reducing persistent pain after craniotomies remains unclear. We therefore tested the primary hypothesis that preoperative ultrasound-guided superficial cervical plexus blocks reduce persistent pain 3 months after suboccipital craniotomies. We conducted a single-center randomized and blinded parallel-group trial. Eligible patients having suboccipital craniotomies were randomly allocated to superficial cervical plexus blocks with 10 ml of 0.5% ropivacaine or a comparable amount of normal saline. Injections were into the superficial layer of prevertebral fascia. The primary outcome was the incidence of persistent pain three months after surgery. From Nov 2021 to August 2023, 292 qualifying patients were randomly allocated to blocks with ropivacaine (n=146) or saline (n=146). The average ± SD age of participating patients was 45±12 years and the duration of surgery was 4.2±1.3 hours. Persistent pain 3 months after surgery was reported by 48 (34%) of patients randomized to ropivacaine versus 73 (51%) in those assigned to saline (relative risk 0.66; 95% CI, 0.50 to 0.88; P = 0.003) in the per-protocol population, and by 53 (36%) of patients randomized to ropivacaine versus 77 (53%) in those assigned to saline (relative risk 0.69, 95% CI, 0.53 to 0.90; P = 0.005) in the intention-to-treat population. Superficial cervical plexus blocks reduce the incidence of persistent incisional pain by about a third in patients recovering from suboccipital craniotomies.

Liver transplantation plus chemotherapy versus chemotherapy alone in patients with permanently unresectable colorectal liver metastases (TransMet): results from a multicentre, open-label, prospective, randomised controlled trial

Despite the increasing efficacy of chemotherapy, permanently unresectable colorectal liver metastases are associated with poor long-term survival. We aimed to assess whether liver transplantation plus chemotherapy could improve overall survival. TransMet was a multicentre, open-label, prospective, randomised controlled trial done in 20 tertiary centres in Europe. Patients aged 18-65 years, with Eastern Cooperative Oncology Group performance score 0-1, permanently unresectable colorectal liver metastases from resected BRAF-non-mutated colorectal cancer responsive to systemic chemotherapy (≥3 months, ≤3 lines), and no extrahepatic disease, were eligible for enrolment. Patients were randomised (1:1) to liver transplantation plus chemotherapy or chemotherapy alone, using block randomisation. The liver transplantation plus chemotherapy group underwent liver transplantation for 2 months or less after the last chemotherapy cycle. At randomisation, the liver transplantation plus chemotherapy group received a median of 21·0 chemotherapy cycles (IQR 18·0-29·0) versus 17·0 cycles (12·0-24·0) in the chemotherapy alone group, in up to three lines of chemotherapy. During first-line chemotherapy, 64 (68%) of 94 patients had received doublet chemotherapy and 30 (32%) of 94 patients had received triplet regimens; 76 (80%) of 94 patients had targeted therapy. Transplanted patients received tailored immunosuppression (methylprednisolone 10 mg/kg intravenously on day 0; tacrolimus 0·1 mg/kg via gastric tube on day 0, 6-10 ng/mL days 1-14; mycophenolate mofetil 10 mg/kg intravenously day 0 to <2 months and switch to everolimus 5-8 ng/mL), and postoperative chemotherapy, and the chemotherapy group had continued chemotherapy. The primary endpoint was 5-year overall survival analysed in the intention to treat and per-protocol population. Safety events were assessed in the as-treated population. The study is registered with ClinicalTrials.gov (NCT02597348), and accrual is complete. Between Feb 18, 2016, and July 5, 2021, 94 patients were randomly assigned and included in the intention-to-treat population, with 47 in the liver transplantation plus chemotherapy group and 47 in the chemotherapy alone group. 11 patients in the liver transplantation plus chemotherapy group and nine patients in the chemotherapy alone group did not receive the assigned treatment; 36 patients and 38 patients in each group, respectively, were included in the per-protocol analysis. Patients had a median age of 54·0 years (IQR 47·0-59·0), and 55 (59%) of 94 patients were male and 39 (41%) were female. Median follow-up was 59·3 months (IQR 42·4-60·2). In the intention-to-treat population, 5-year overall survival was 56·6% (95% CI 43·2-74·1) for liver transplantation plus chemotherapy and 12·6% (5·2-30·1) for chemotherapy alone (HR 0·37 [95% CI 0·21-0·65]; p=0·0003) and 73·3% (95% CI 59·6-90·0) and 9·3% (3·2-26·8), respectively, for the per-protocol population. Serious adverse events occurred in 32 (80%) of 40 patients who underwent liver transplantation (from either group), and 69 serious adverse events were observed in 45 (83%) of 54 patients treated with chemotherapy alone. Three patients in the liver transplantation plus chemotherapy group were retransplanted, one of whom died postoperatively of multi-organ failure. In selected patients with permanently unresectable colorectal liver metastases, liver transplantation plus chemotherapy with organ allocation priority significantly improved survival versus chemotherapy alone. These results support the validation of liver transplantation as a new standard option for patients with permanently unresectable liver-only metastases.

Safety and immunogenicity of mRNA-based seasonal influenza vaccines formulated to include multiple A/H3N2 strains with or without the B/Yamagata strain in US adults aged 50–75 years: a phase 1/2, open-label, randomised trial

Inclusion of additional influenza A/H3N2 strains in seasonal influenza vaccines could expand coverage against multiple, antigenically distinct, cocirculating A/H3N2 clades and potentially replace the no longer circulating B/Yamagata strain. We aimed to evaluate the safety and immunogenicity of three next-generation seasonal influenza mRNA vaccines with different compositions that encode for haemagglutinins of multiple A/H3N2 strains, with or without the B/Yamagata strain, in adults. This randomised, open-label, phase 1/2 trial enrolled healthy adults aged 50-75 years across 22 sites in the USA. Participants were randomly assigned (1:1:1:1:1:1:1) via interactive response technology to receive a single dose of mRNA-1011.1 (pentavalent; containing one additional A/H3N2 strain [Newcastle]), mRNA-1011.2 (quadrivalent; B/Yamagata replaced with one additional A/H3N2 strain [Newcastle]), mRNA-1012 at one of two dose levels (pentavalent; B/Yamagata replaced with two additional A/H3N2 strains [Newcastle and Hong Kong]), or one of three quadrivalent mRNA-1010 controls each encoding one of the A/H3N2 study strains. The primary outcomes were safety, evaluated in all randomly assigned participants who received a study vaccination (safety population), and reactogenicity, evaluated in all participants from the safety population who contributed any solicited adverse reaction data (solicited safety population). The secondary outcome was humoral immunogenicity of investigational mRNA vaccines at day 29 versus mRNA-1010 control vaccines based on haemagglutination inhibition antibody (HAI) assay in the per-protocol population. Here, we summarise findings from the planned interim analysis after participants had completed day 29. The study is registered with ClinicalTrials.gov, NCT05827068, and is ongoing. Between March 27 and May 9, 2023, 1183 participants were screened for eligibility, 699 (59·1%) were randomly assigned, and 696 (58·8%) received vaccination (safety population, n=696; solicited safety population, n=694; per-protocol population, n=646). 382 (55%) of the 696 participants in the safety population self-reported as female and 314 (45%) as male. Frequencies of solicited adverse reactions were similar across vaccine groups; 551 (79%) of 694 participants reported at least one solicited adverse reaction within 7 days after vaccination and 83 (12%) of 696 participants reported at least one unsolicited adverse event within 28 days after vaccination. No vaccine-related serious adverse events or deaths were reported. All three next-generation influenza vaccines elicited robust antibody responses against vaccine-matched influenza A and B strains at day 29 that were generally similar to mRNA-1010 controls, and higher responses against additional A/H3N2 strains that were not included within respective mRNA-1010 controls. Day 29 geometric mean fold rises in HAI titres from day 1 against vaccine-matched A/H3N2 strains were 3·0 (95% CI 2·6-3·6; Darwin) and 3·1 (2·6-3·8; Newcastle) for mRNA-1011.1; 3·3 (2·7-4·1; Darwin) and 4·2 (3·4-5·2; Newcastle) for mRNA-1011.2; 3·4 (2·9-4·0; Darwin), 4·5 (3·6-5·5; Newcastle), and 5·1 (4·2-6·2; Hong Kong) for mRNA-1012 50·0 μg; and 2·6 (2·2-3·1; Darwin), 3·7 (3·0-4·6; Newcastle), and 4·1 (3·3-5·1; Hong Kong) for mRNA-1012 62·5 μg. Inclusion of additional A/H3N2 strains did not reduce responses against influenza A/H1N1 or influenza B strains, and removal of B/Yamagata did not affect responses to B/Victoria. These data support the continued clinical development of mRNA-based next-generation seasonal influenza vaccines with broadened influenza A/H3N2 strain coverage. Moderna.

Safety of acamprosate for alcohol use disorder after liver transplant: A pilot randomized controlled trial.

Acamprosate is a therapy for alcohol use disorder, but data on feasibility and safety in recipients of liver transplants are lacking. This was a single-center unblinded prospective pilot randomized controlled trial of adults (≥18y) with liver transplant for alcohol-associated liver disease enrolled between 2021 and 2023, who were randomized 2:1 to the intervention of acamprosate (666mg dose 3 times daily) or standard of care (SOC) over 14 weeks. Outcomes included safety (prevalence of adverse events [AEs]), feasibility (weekly survey response rate >60%), adherence (self-reported acamprosate use >60%), and efficacy (reduction in Penn Alcohol Craving Scale), and relapse-blood phosphatidylethanol (≥20ng/mL/reported alcohol use) evaluated by standardized weekly surveys. The efficacy analysis was done in both the intention-to-treat (excluding withdrawals before medication administration) and per-protocol population (excluding withdrawals/<4 weeks participation). Of 78 participants who were approached, 30 enrolled (19 acamprosate and 11 SOC) with similar baseline characteristics. Eight participants withdrew (6 acamprosate before medication administration and 2 SOC). AEs were similar between acamprosate and SOC groups (92.3% vs. 90.0%, p > 0.99), including grade 3 AEs (53.9% vs. 60.0%, p > 0.99) with no reported grade 4/5 AEs. Survey response rates were similar in acamprosate versus SOC groups (61.0% vs. 76.0%, p = 0.19), and 69.0% were acamprosate adherents. Baseline Penn Alcohol Craving Scale values were low with no difference by the group in median absolute change in Penn Alcohol Craving Scale for intention-to-treat (0, IQR: -4 to 0 vs. 0, IQR: 0-0, p = 0.32), and per-protocol analyses (-1, IQR: -6 to 0 vs. 0, IQR: -0 to 0, p = 0.36). There was no reported or biochemical evidence of alcohol relapse. In this pilot study, preliminary data suggest that acamprosate may be safe and feasible. These data can inform larger studies and clinician efforts to address alcohol use disorder in post-liver transplant care (ClinicalTrials.gov, Number: NCT06471686).

Iloprost and Organ Dysfunction in Adults With Septic Shock and Endotheliopathy

Soluble thrombomodulin is a marker of endotheliopathy, and iloprost may improve endothelial function. In patients with septic shock, high plasma levels of soluble thrombomodulin (>10 ng/mL) have been associated with worse organ dysfunction and mortality. To assess the effects of treatment with iloprost vs placebo on the severity of organ failure in patients with septic shock and plasma levels of soluble thrombomodulin higher than 10 ng/mL. This investigator-initiated, adaptive, parallel group, stratified, double-blind randomized clinical trial was conducted between November 1, 2019, and July 5, 2022, at 6 hospitals in Denmark. The trial had a maximum sample size of 380, with an interim analysis for futility only at 200 patients with 90 days of follow-up. In total, 279 adults in the intensive care unit (ICU) with septic shock and endotheliopathy were included. Patients were randomized 1:1 to masked intravenous infusion of iloprost, 1 ng/kg/min (n = 142), or placebo (n = 137) for 72 hours. The primary outcome was mean daily Sequential Organ Failure Assessment (SOFA) score in the ICU adjusted for trial site and baseline SOFA score for the per-protocol population. SOFA scores for each of the 5 organ systems ranged from 0 to 4, with higher scores indicating more severe dysfunction (maximum score, 20). The secondary outcomes included serious adverse reactions and serious adverse events at 7 days and mortality at 90 days. Of 279 randomized patients, data from 278 were analyzed (median [IQR] age, 69 [58-77] years; 171 (62%) male), 142 in the iloprost group and 136 in the placebo group. The trial was stopped for futility at the planned interim analysis. The mean [IQR] daily SOFA score was 10.6 (6.4-14.8) in the iloprost group and 10.5 (5.9-15.5) in the placebo group (adjusted mean difference, 0.2 [95% CI, -0.8 to 1.2]; P = .70). Mortality at 90 days in the iloprost group was 57% (81 of 142) vs 51% (70 of 136) in the placebo group (adjusted relative risk, 1.12 [95% CI, 0.91-1.40]; P = .33). Serious adverse events occurred in 26 of 142 patients (18%) for the iloprost group vs 20 of 136 patients (15%) for the placebo group (adjusted relative risk, 1.25 [95% CI, 0.73-2.15]; P = .52). Only 1 serious adverse reaction was observed. In this randomized clinical trial of adults in the ICU with septic shock and severe endotheliopathy, infusion of iloprost, 1 ng/kg/min, for 72 hours did not reduce mean daily SOFA scores compared with placebo. In a clinical context, administration of iloprost will be unlikely to improve outcome in these patients. ClinicalTrials.gov Identifier: NCT04123444.

Efficacy and safety of autologous whole blood clot in diabetic foot ulcers: a randomised controlled trial.

Diabetic foot ulcers (DFUs) present a significant global health challenge, resulting in high morbidity and economic costs. Current available treatments often fail to achieve satisfactory healing rates, highlighting the need for novel therapies. This study evaluated the safety and efficacy of a novel autologous whole blood clot (AWBC)-a blood-based, biodegradable provisional matrix-in conjunction with standard of care (SoC) when compared to SoC alone in the treatment of hard-to-heal DFUs. A multicentre, prospective, blinded assessor, randomised controlled trial was conducted at 16 sites across the US, South Africa and Turkey. A cohort of patients with hard-to-heal DFUs was enrolled and randomised to either the AWBC group or the control group. The primary endpoint was complete wound closure at 12 weeks, while secondary endpoints included time to heal and percentage area reduction (PAR) at four and eight weeks. Data were analysed using both intention-to-treat (ITT) and per-protocol (PP) populations. The cohort included 119 patients. AWBC treatment resulted in a significantly higher healing rate compared to the control in both ITT (41% versus 15%, respectively; p=0.002) and PP populations (51% versus 18%, respectively; p=0.0075). AWBC treatment also resulted in a shorter mean time to heal and higher durability of wound closure. Safety analysis showed a similar incidence of adverse events (AEs) between groups, with no device-related AEs. The AWBC system, by modulating the wound microenvironment and providing a functional extracellular matrix, offered a promising new approach to treating hard-to-heal DFUs, demonstrating superior healing outcomes compared to SoC alone in this study.

The Efficacy Of Continuous Non-Inhaled Intranasal Carbon Dioxide (CO2) In The Abortive Treatment Of Migraine: Results From Three Randomized, Double-Blinded, Placebo-Controlled Trials

Objective: Determining the efficacy, tolerability, and safety of continuous non-inhaled intranasal carbon dioxide (CO2) in the acute or abortive treatment of migraine. Background: Carbon dioxide gas infused in the nose and sinuses potentially blocks trigeminal nerve activation and subsequent neuropeptide release, probably through inhibition of voltage-gated channels. The pathogenesis of the migraine headache involves activation of the trigeminocervical system, which establishes the nociceptive innervation of the head through the trigeminal and occipital nerves. Methods: In three randomized, double-blinded, placebo-controlled trials, we randomized 350 subjects with migraine as defined by the International Headache Society (intent-to-treat population). We determined tolerability and safety in the 317 subjects who we exposed to treatment up to 24 hours post-dose (modified intent-to-treat population). We determined efficacy in the modified intent-to-treat and per-protocol populations at 15 minutes, half, one, two, and twenty-four hours post-dose in terms of pain freedom, freedom from headache-associated symptoms, and headache relief, treating migraine headaches of mild, moderate, or severe intensity. Results: We did not observe clinically significant systemic effects, either on blood carbon dioxide pressure or on the cardiovascular or respiratory system. No serious or clinically significant adverse events occurred and those reported were predominantly local, transient, and short-lived. Headache intensity strongly and in a negative way determined the efficacy of treatment with carbon dioxide but not with placebo, and even when placebo consisted of no gas, blinding seemed adequate. Conclusions: Continuous non-inhaled intranasal carbon dioxide seems safe, relatively well tolerated, and moderately effective for the acute or abortive treatment of migraine.

A Randomized Controlled Trial Comparing the Effects of Vilazodone, Escitalopram, and Vortioxetine Monotherapy on the Metabolic Parameters in Patients With Major Depressive Disorder.

The coexistence of major depressive disorder (MDD) and metabolic illness could culminate in an aberrant metabolic profile. Individuals with MDD and type 2 diabetes mellitus (T2DM) are more likely to have impaired metabolic indicators. Effective antidepressant therapy can alleviate depressive symptoms and metabolic abnormalities. We focused on the effects of vilazodone, escitalopram, and vortioxetine on metabolic indices. Our research aimed to examine changes after 16 weeks of intervention in the glycemic indices, serum creatinine, lipid profile, hepatic parameters, and the Hamilton Depression Rating Scale (HDRS) 17-item version. A three-arm, randomized, open-label trial with 96 MDD patients was executed. Participants were divided into three distinct groups in a 1:1:1 ratio for 16 weeks and issued tablets of vilazodone (20-40 mg/day), escitalopram (10-20 mg/day), or vortioxetine (5-20 mg/day). Vilazodone and vortioxetine were the two test medications, while escitalopram served as the control. We stratified the participants as non-diabetics and diabetics. Follow-up appointments were slated four weeks after the initial visit. HDRS scores and other metabolic indicators were assessed at each visit in the per-protocol (PP) population. After 12 weeks, glycated hemoglobin (HbA1c) levels were measured. Lower HDRS scores indicated that depression-related symptoms had improved. We investigated the relationship between the 16-week differences in the fasting blood sugar(FBS) and HDRS scores. The Kruskal-Wallis test, Bonferroni correction, and Pearson correlation were all used in our analysis. We registered our trial prospectively in the Clinical Trial Registry of India (CTRI) (2022/07/043808). Of the 134 people we screened, 119 (81.34%) were deemed eligible. The PP population included 96 (88.07%) of those who completed the 16-week study. The population's average age was 46.3 ± 6.2 years. Across all study groups, the median baseline HDRS score was 30.0 (p = 0.964). At 16 weeks, the equivalent scores dropped to 15.0, 14.0, and 13.0 (p = 0.002). The median FBS levels at baseline and 16 weeks were 100.5, 104.0, and 98.0 (p = 0.491) and 91.5, 98.5, and 91.5 (p = 0.561), respectively. The post hoc analysis manifested no statistically significant changes between any parameters. Except for the reductions in glycemic indices in diabetic patients, no other data differed significantly. There was a positive relationship between FBS and HDRS scores. Irrespective of the diabetic situation, all three drugs substantially lowered HDRS scores. People with diabetes experienced noticeable declines in glycemic indices. Despite this, the patients' other metabolic indicators showed no significant alterations. We urge additional research with a larger sample size to investigate these medications' long-term impact on various metabolic indicators.

Hepatitis C treatment outcome among people in prison: The SToP-C study.

Hepatitis C virus (HCV) burden is higher among people in prison given high prevalence of injecting drug use. This study evaluated direct-acting antiviral (DAA) treatment outcome in prisons. The Surveillance and Treatment of Prisoners with hepatitis C (SToP-C) study enrolled individuals incarcerated in four Australian prisons (2017-2019). Participants with detectable HCV RNA were offered sofosbuvir-velpatasvir for 12 weeks. Sustained virological response (SVR) was assessed in intention-to-treat (ITT; participants commencing treatment and due for SVR assessment before study close) and per-protocol (PP; participants with documented treatment completion and SVR assessment) populations. Among 799 participants with HCV, 324 (41%) commenced treatment (94% male; median age, 32 years; median duration of incarceration, 9 months). In ITT population (n = 310), 201 had documented treatment completion (65% [95% CI: 59-70]), and 137 achieved SVR (ITT-SVR: 44% [95% CI: 39-50]). In PP population (n = 143), 137 achieved SVR (PP-SVR: 96% [95% CI: 91-98]). Six participants had quantifiable HCV RNA at SVR assessment from treatment failure (n = 2) or reinfection (n = 4). Release or inter-prison transfer was common reasons for no documented treatment completion (n = 106/109 [97%]) and no SVR assessment (n = 57/58 [98%]). In ITT analysis, longer incarceration was associated with increased SVR (adjusted OR per month 1.03 [95% CI: 1.01-1.04]). Among participants who completed DAA treatment and were assessed for SVR, treatment outcome was consistent with non-prison clinical studies. However, most individuals did not complete treatment or lacked study-documented treatment outcome due to release or transfer. Strategies to accommodate dynamic prisoner populations are required to ensure continuity of HCV care, including treatment completion and post-treatment care.

User engagement in clinical trials of digital mental health interventions: a systematic review

IntroductionDigital mental health interventions (DMHIs) overcome traditional barriers enabling wider access to mental health support and allowing individuals to manage their treatment. How individuals engage with DMHIs impacts the intervention effect. This review determined whether the impact of user engagement was assessed in the intervention effect in Randomised Controlled Trials (RCTs) evaluating DMHIs targeting common mental disorders (CMDs).MethodsThis systematic review was registered on Prospero (CRD42021249503). RCTs published between 01/01/2016 and 17/09/2021 were included if evaluated DMHIs were delivered by app or website; targeted patients with a CMD without non-CMD comorbidities (e.g., diabetes); and were self-guided. Databases searched: Medline; PsycInfo; Embase; and CENTRAL. All data was double extracted. A meta-analysis compared intervention effect estimates when accounting for engagement and when engagement was ignored.ResultsWe identified 184 articles randomising 43,529 participants. Interventions were delivered predominantly via websites (145, 78.8%) and 140 (76.1%) articles reported engagement data. All primary analyses adopted treatment policy strategies, ignoring engagement levels. Only 19 (10.3%) articles provided additional intervention effect estimates accounting for user engagement: 2 (10.5%) conducted a complier-average-causal effect (CACE) analysis (principal stratum strategy) and 17 (89.5%) used a less-preferred per-protocol (PP) population excluding individuals failing to meet engagement criteria (estimand strategies unclear). Meta-analysis for PP estimates, when accounting for user engagement, changed the standardised effect to -0.18 95% CI (-0.32, -0.04) from − 0.14 95% CI (-0.24, -0.03) and sample sizes reduced by 33% decreasing precision, whereas meta-analysis for CACE estimates were − 0.19 95% CI (-0.42, 0.03) from − 0.16 95% CI (-0.38, 0.06) with no sample size decrease and less impact on precision.DiscussionMany articles report user engagement metrics but few assessed the impact on the intervention effect missing opportunities to answer important patient centred questions for how well DMHIs work for engaged users. Defining engagement in this area is complex, more research is needed to obtain ways to categorise this into groups. However, the majority that considered engagement in analysis used approaches most likely to induce bias.

Immune killer cells treatment for previously treated stage IV NSCLC patients

The 5-year survival is poor for stage IV non-small cell lung cancer (NSCLC). Recently, cell immunotherapy has emerged as a new treatment strategy. This study aimed to evaluate the efficacy and safety of Immune killer cells (IKC) in patients with stage IV NSCLC after the failure of prior chemotherapy. This study enrolled 26 patients with stage IV NSCLC who failed at least two lines of chemotherapy with or without targeted therapy. The IKC was given alone weekly for 24 weeks. The primary endpoint was progression-free survival (PFS). Secondary outcomes included overall survival (OS), pain intensity, quality of life (QOL), and safety. The median PFS for the intent-to-treat (ITT) population (i.e., all enrolled patients) was 3.8 month. In the per-protocol (PP) population (i.e., patients receiving > 12 IKC infusions), the median PFS was 5.6 months. Moreover, the ITT population showed a 1-year survival rate of 60.0%, while that for the PP population was 85.7%. Only 7 out of 200 AEs (3.5%) were related to the IKC infusion, and they were all rated as grade 1 in severity. The IKC infusion was well tolerated. This novel immunotherapy prolonged the PFS and improved the survival compared with historical data. It might be a potential treatment strategy for stage IV NSCLC patient who failed prior chemotherapy.ClinicalTrials.gov identifier: NCT03499834.

Efficacy and safety of peginterferon beta-1a compared to interferon beta-1a in relapsing remitting multiple sclerosis patients: A phase 3, randomized, non-inferiority clinical trial (PEGINTEGRITY)

BackgroundMultiple sclerosis (MS) is a prevalent, disabling, inflammatory, neurodegenerative disease that typically manifests during a highly productive stage of life. Interferon beta-1a was among the first approved disease-modifying therapies for MS and remains among the first-line treatment options. Pegylation of the interferon beta-1a molecule prolongs its half-life while maintaining its efficacy and safety profile. In PEGINTEGRITY study, we aimed to compare peginterferon beta-1a with interferon beta-1a in terms of efficacy and safety in relapsing-remitting multiple sclerosis (RRMS) patients. MethodsThis study was a randomized, active-controlled, parallel-group, multi-center Phase 3 trial conducted in Iran in participants with RRMS. Participants received 125 µg of subcutaneous peginterferon beta-1a every two weeks or 30 µg of intramuscular interferon beta-1a once a week for up to 96 weeks. The primary outcome was the non-inferiority of peginterferon beta-1a to interferon beta-1a in reducing annualized relapse rate (ARR). Other outcomes included the number of patients with 12-week confirmed disability progression, the number of new or newly-enlarging T2 hyperintense lesions, the number of gadolinium-enhancing lesions, the number of new T1 hypointense lesions, the volume of new or newly-enlarging T2 hyperintense lesions, changes in brain volume, immunogenicity, and safety assessments. ResultsA total of 168 patients who met the eligibility criteria were enrolled and assigned to two arms of the study, each consisting of 84 participants. Totally, 41 participants (24 patients in the peginterferon beta-1a group and 17 patients in the interferon beta-1a group) were withdrawn from the study. The withdrawn patients were included in the per-protocol analysis for the period of time they were in the study. In 96 weeks, in the per-protocol population, the ARR was 0.05 in the peginterferon beta-1a group versus 0.11 in the interferon beta-1a group, which does not reflect a statistically significant difference (p=0.09; 95 % CI, 0.18-1.14). Considering the upper limit of the one-sided 95 % CI of the rate ratio of peginterferon beta-1a compared to interferon beta-1a, as well as the non-inferiority margin, it can be concluded that the primary outcome was met. The results were also comparable for other efficacy and safety outcomes. ConclusionThe results demonstrate the non-inferiority of peginterferon beta-1a to interferon beta-1a with similar efficacy in 96-week ARR in RRMS patients. Both arms were also comparable in other efficacy outcomes and safety profiles with no statistically significant differences. These findings support considering peginterferon beta-1a as a safe and efficient option in patients with RRMS.This study was registered on Iranian Registry of Clinical Trials (IRCT201612306135N8) and clinicaltrials.gov (NCT05242133).

Dual therapy based on co-formulated darunavir/ritonavir plus lamivudine for initial therapy of HIV infection: The ANDES randomized controlled trial

Tenofovir-containing antiretroviral therapy regimens may have long-term toxicity-related side effects. This study aimed to compare the virological efficacy of co-formulated darunavir/ritonavir plus lamivudine with darunavir/ritonavir plus tenofovir and emtricitabine or lamivudine. The ANDES study was a 48-week, phase 4, randomized, open-label, non-inferiority trial in treatment-naïve adults living with human immunodeficiency virus (HIV). Patients were randomized on a 1:1 basis to receive a daily oral regimen of either dual therapy based on a generic co-formulation of darunavir/ritonavir (800/100 mg) plus a generic lamivudine 300 mg pill, or triple therapy with darunavir/ritonavir plus tenofovir/emtricitabine (300/200 mg) or tenofovir/lamivudine (300/300 mg). The primary endpoint was the proportion of patients with a viral load of <50 copies/mL at week 48 in the intention-to-treat population. The US Food and Drug Administration snapshot algorithm and a non-inferiority margin of -12% were used. The secondary objective was to analyse safety in the per-protocol population. This study has been registered at ClinicalTrials.gov (NCT02770508). Between November 2015 and 31 October 2020, 336 participants were assigned at random to the triple therapy arm (n=165) or the dual therapy arm (n=171). After 48 weeks, 153 patients in the triple therapy group (93%) and 155 patients in the dual therapy group (91%) achieved virological suppression (difference -2.1%, 95% confidence interval -7.0 to 2.9). Drug-related adverse events were more common in the triple therapy group (P=0.04). Two toxicity-related events led to discontinuation in each group. Co-formulated darunavir/ritonavir plus lamivudine showed non-inferiority and a safer toxicity profile compared with the standard-of-care triple therapy regimen including tenofovir in treatment-naïve patients.

Ultrasound-guided supraclavicular block versus Bier block for emergency reduction of upper limb injuries: statistical analysis plan

BackgroundUltrasound-guided supraclavicular block (UGSCB) is an emerging technique gaining interest amongst emergency physicians that provides regional anaesthesia to the upper limb to tolerate painful procedures. It offers an alternative to the more traditional technique of a Bier block (BB). However, the effectiveness or safety of UGSCB when performed in the emergency department (ED) is unclear.MethodsSUPERB (SUPraclavicular block for Emergency Reduction versus Bier block) is a prospective open-label non-inferiority randomised controlled trial comparing the effectiveness of UGSCB versus BB for closed reduction of upper limb fractures and/or dislocations. Adult patients presenting with upper limb fracture and/or dislocation requiring closed reduction in ED were randomised to either UGSCB or BB. Once regional anaesthesia is obtained, closed reduction of the injured part was performed and immobilised. The primary outcome is maximal pain experienced during closed reduction measured via a visual analogue scale (VAS). Secondary outcomes include post-reduction pain, patient satisfaction, total opioid requirement in ED, ED length of stay, adverse events and regional anaesthesia failure.ResultsPrimary outcome analysis will be performed using both the intention-to-treat and per-protocol populations. The between-group difference in maximum pain intensity will be assessed using linear regression modelling with trial group allocation (UGSCB vs BB) included as a main affect. A pre-specified non-inferiority margin of 20 mm on the VAS scale will be used to establish non-inferiority of UGSCB compared to BB.ConclusionSUPERB is the first randomised controlled trial to investigate the effectiveness and safety of UGSCB in the ED. The trial has the potential to demonstrate that UGSCB is an alternative safe and effective option for the management of upper extremity emergencies in the ED.

Completion axillary lymph node dissection for the identification of pN2–3 status as an indication for adjuvant CDK4/6 inhibitor treatment: a post-hoc analysis of the randomised, phase 3 SENOMAC trial

In luminal breast cancer, adjuvant CDK4/6 inhibitors (eg, abemaciclib) improve invasive disease-free survival. In patients with T1-2, grade 1-2 tumours, and one or two sentinel lymph node metastases, completion axillary lymph node dissection (cALND) is the only prognostic tool available that can reveal four or more nodal metastases (pN2-3), which is the only indication for adjuvant abemaciclib in this setting. However, this technique can lead to substantial arm morbidity in patients. We aimed to pragmatically describe the potential benefit and harm of this strategy on the individual patient level in patients from the ongoing SENOMAC trial. In the randomised, phase 3, SENOMAC trial, patients aged 18 years or older, of any performance status, with clinically node-negative T1-T3 breast cancer and one or two sentinel node macrometastases from 67 sites in five European countries (Denmark, Germany, Greece, Italy, and Sweden) were randomly assigned (1:1), via permutated block randomisation (random block size of 2 and 4) stratified by country, to either cALND or its omission (ie, they had a sentinel lymph node biopsy only). The primary outcome is overall survival, which is yet to be reported. In this post-hoc analysis, patients from the SENOMAC per-protocol population, with luminal oestrogen-receptor positive, HER2-negative, T1-2, histological grade 1-2 breast cancer, with tumour size of 5 cm or smaller were selected to match the characteristics of cohort 1 of the monarchE trial who would only have an indication for adjuvant abemaciclib if found to have 4 or more nodal metastases. The primary study objective was to determine the number of patients who developed patient-reported severe or very severe impairment of physical arm function after cALND (as measured by the Lymphedema Functioning, Disability, and Health [Lymph-ICF] Questionnaire) 1 year after surgery to avoid one invasive disease-free survival event at 5 years with 2 years of adjuvant abemaciclib, using invasive disease-free survival event data from cohort 1 of the monarchE trial. The SENOMAC trial is registered with ClincialTrials.gov, NCT02240472, and is closed to accrual and ongoing. Between Jan 31, 2015, and Dec 31, 2021, 2766 patients were enrolled in SENOMAC and randomly assigned to cALND (n=1384) or sentinel node biopsy only (n=1382), of whom 2540 were included in the per-protocol population. 1705 (67%) of 2540 patients met this post-hoc study's eligibility criteria, of whom 802 (47%) had a cALND and 903 (53%) had a sentinel lymph node biopsy only. Median age at randomisation was 62 years (IQR 52-71), 1699 (>99%) of 1705 patients were female, and six (<1%) were male. Among 1342 patients who responded to questionnaires, after a median follow-up of 45·2 months (IQR 25·6-59·8; data cutoff Nov 17, 2023), patient-reported severe or very severe impairment of physical arm function was reported in 84 (13%) of 634 patients who had cALND versus 30 (4%) of 708 who had sentinel lymph node biopsy only (χ2 test p<0·0001). To avoid one invasive disease-free survival event at 5 years with adjuvant abemaciclib, cALND would need to be performed in 104 patients, and would result in nine patients having severe or very severe impairment of physical arm function 1 year after surgery. As a method to potentially identify an indication for abemaciclib, and subsequently avoid invasive disease-free survival events at 5 years with 2 years of adjuvant abemaciclib, cALND carries a substantial risk of severe or very severe arm morbidity and so cALND should be discouraged for this purpose.

Addition of Metastasis-Directed Therapy to Systemic Therapy for Oligometastatic Pancreatic Ductal Adenocarcinoma (EXTEND): A Multicenter, Randomized Phase II Trial.

The EXTEND trial tested the hypothesis that adding comprehensive metastasis-directed therapy (MDT) to chemotherapy would improve progression-free survival (PFS) over chemotherapy alone among patients with oligometastatic pancreatic ductal adenocarcinoma (PDAC). EXTEND (ClinicalTrials.gov identifier: NCT03599765) is a multicenter, phase II basket trial randomly assigning patients with ≤five metastases 1:1 to MDT plus systemic therapy versus systemic therapy. Disease progression was defined by radiologic criteria (RECIST v1.1), clinical progression, or death. The primary end point was PFS in the per-protocol population, evaluated after all patients achieved at least 6 months of follow-up. Exploratory end points included systemic immune response measures. Between March 19, 2019, and February 13, 2023, 41 patients were randomly assigned and 40 were eligible for the primary analysis of PFS (19 patients in the MDT arm; 21 patients in the control arm). At a median follow-up time of 17 months, the median PFS time was 10.3 months (95% CI, 4.6 to 14.0) in the MDT arm versus 2.5 months (95% CI, 1.7 to 5.1) in the control arm. PFS was significantly improved by the addition of MDT to systemic therapy (P = .030 for stratified log-rank test) with a hazard ratio of 0.43 (95% CI, 0.20 to 0.94). No grade ≥3 or greater adverse events related to MDT were observed. Systemic immune activation events were associated with MDT and correlated with improved PFS. This study supports the addition of MDT to systemic therapy for patients with oligometastatic PDAC. Induction of systemic immunity is a possible mechanism of benefit. These results warrant confirmatory trials to refine treatment strategy and provide external validation.
