Superonasal vs Inferonasal Subconjunctival Gel Stent Placement in Patients with Glaucoma.

Aim and background: To compare the safety and efficacy of subconjunctival gel stent implantation in the superonasal (SN) vs inferonasal (IN) quadrants in the treatment of glaucoma. Materials and methods: Patients with a history of IN (n = 29) or SN, (n = 96) gel stent placement with ≥3 months of follow-up were included. Intraocular pressure (IOP) and the number of glaucoma medications were collected preoperatively and postoperatively at months 1, 3, 6, and 12. Safety measures included the number of bleb needlings, complication rate, and additional surgeries. Results: Mean baseline IOP was 32.4 ± 11.7 mm Hg in the IN group and 21.6 ± 9.2 mm Hg in the SN group (p < 0.01). IOP was similar between groups at 3 months (IN = 15.8, SN = 15.6, p = 0.45), 6 months (IN = 17.4, SN = 15, p = 0.13), and 12 months (IN = 17.9, SN = 14.7, p = 0.15) follow-up. The number of glaucoma medications was also similar at 3 months (p = 0.31), 6 months (p = 0.24), and 12 months (p = 0.39) follow-up. Bleb needling rates were similar with 51.7% (15/29) in the IN group vs 42.7% (41/96) in the SN group (p = 0.39) and subjects requiring further surgery were 17.2% (5/29) in the IN group vs 24.0% (23/96) in the SN group (p = 0.45). Conclusion: Both IN and SN subconjunctival gel stent placements provide favorable safety and efficacy when treating open-angle glaucoma, with a meaningful decrease in medication use and IOP. Clinical significance: Implantation of the subconjunctival gel stent in the IN quadrant is an effective and safe alternative to superior implantation in refractory glaucoma.

Remimazolam in General Anesthesia: A Comprehensive Review of Its Applications and Clinical Efficacy.

Remimazolam is a novel ultra-short-acting benzodiazepine with a unique pharmacokinetic profile that makes it an attractive option for use in general anesthesia. This review paper provides an in-depth analysis of remimazolam's applications in the field of general anesthesia, focusing on its pharmacological properties, clinical efficacy, safety profile, and potential advantages compared to other anesthetic agents. Remimazolam acts on GABAa receptors, offering rapid onset and recovery times due to its unique metabolic pathway involving tissue esterases. Clinical trials have demonstrated its efficacy in procedural sedation and general anesthesia, showing a favorable safety profile with minimal cardiovascular and respiratory depression. Compared to traditional anesthetics such as propofol, remimazolam presents distinct advantages, including predictable pharmacokinetics, reduced risk of prolonged sedation, and a reliable safety margin. These attributes position remimazolam as a promising agent in various clinical settings. The purpose of this review is to synthesize current evidence on remimazolam and discuss its potential to improve clinical outcomes in anesthesia practice.

Retrospective Study of the Use of Heparins in Pregnant Women and in vitro Testing on the HCT 116 Colorectal Carcinoma Cell Line.

Introduction: Pregnant women manifest an increased risk of developing coagulation disorders. Unfractionated heparin (HEP) and low-molecular-weight heparin (LMWHep) are considered as selective medication in the case of pregnancy which needs anticoagulant treatment. In addition to anticoagulant properties, HEP and its derivatives manifest other properties including anti-cancer potential. According to Globocan's latest data, colorectal cancer (CRC) is the second most encountered form of malignancy in the case of women, manifesting some special particularities, as confusion of symptoms from cancer with symptoms encountered normally in pregnant women (such as constipation or rectal bleeding), delayed diagnosis because of limitations imposed both for the fetus and for the mother, and the need for special treatment. Aim: The aim of the present work is to follow the incidence and safety of consumption of HEP and LMWHep in the case of pregnant women and to analyze their potential on the HCT 116 colorectal carcinoma cells. Results: Analyzing the consumption of heparins in case of pregnant women hospitalized from 01.01.2022 to 31.12.2022 at the Pius Brînzeu" Emergency Clinical Hospital from Timisoara, Obstetrics and Gynecology Clinic I, it was observed that 44,6% of the patients were administered the following medication and no administration risks were observed. When tested on HCT 116 cells, heparins manifested a significant anti-migratory effect (with wound healing rates of 2,6%, when tested with HEP 100 UI concentration and 14.52% wound healing rates in case of fraxiparine 100 UI). In addition, different signs of apoptosis were observed, suggesting the pro-apoptotic potential of the tested substances. Conclusions: Heparins remain the preferred medication to be administered to pregnant women with the potential for coagulation disorders, showing a high safety profile. Testing on the cancerous line of colorectal carcinoma highlights important properties that stimulate future studies, to establish the anti-tumor potential and the exact mechanism of action.

Proprotein convertase subtilisin/kexin type 9 inhibitors in peripheral artery disease: A review of efficacy, safety, and outcomes.

Peripheral artery disease (PAD) is a common condition characterized by atherosclerosis in the peripheral arteries, associated with concomitant coronary and cerebrovascular diseases. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are a class of drugs that have shown potential in hypercholesterolemic patients. This review focuses on the efficacy, safety, and clinical outcomes of PCSK9 inhibitors in PAD based on the literature indexed by PubMed. Trials such as FOURIER and ODYSSEY demonstrate the efficacy of evolocumab and alirocumab in reducing cardiovascular events, offering a potential treatment option for PAD patients. Safety evaluations from trials show few adverse events, most of which are injection-site reactions, indicating the overall safety profile of PCSK9 inhibitors. Clinical outcomes show a reduction in cardiovascular events, ischemic strokes, and major adverse limb events. However, despite these positive findings, PCSK9 inhibitors are still underutilized in clinical practice, possibly due to a lack of awareness among care providers and cost concerns. Further research is needed to establish the long-term effects and cost-effectiveness of PCSK9 inhibitors in PAD patients.

Assessing the Efficacy of Bortezomib and Dexamethasone for Induction and Maintenance Therapy in Relapsed/Refractory Cutaneous T-Cell Lymphoma: A Phase II CISL1701/BIC Study.

Purpose: This multicenter, open-label, phase II trial evaluated the efficacy and safety of bortezomib combined with dexamethasone for the treatment of relapsed/refractory cutaneous T-cell lymphoma (CTCL) in previously treated patients across 14 institutions in South Korea. Patients and Methods: Between September 2017 and July 2020, 29 patients with histologically confirmed CTCL received treatment, consisting of eight 4-week cycles of induction therapy followed by maintenance therapy, contingent upon response, for up to one year. The primary endpoint was the proportion of patients achieving an objective global response. Results: Thirteen (44.8%) of the 29 patients achieved an objective global response, including two complete responses. The median progression-free survival (PFS) was 5.8 months, with responders showing a median PFS of 14.0 months. Treatment-emergent adverse events were generally mild, with a low incidence of peripheral neuropathy and hematologic toxicities. Despite the trend toward shorter PFS in patients with higher mutation burdens, genomic profiling before and after treatment showed no significant emergence of new mutations indicative of disease progression. Conclusion: This study supports the use of bortezomib and dexamethasone as a viable and safe treatment option for previously treated CTCL, demonstrating substantial efficacy and manageability in adverse effects. Further research with a larger cohort is suggested to validate these findings and explore the prognostic value of mutation profiles.

Preclinical studies of BB-1701, a HER2-targeting eribulin-containing ADC with potent bystander effect and ICD activity.

BACKGROUND: Several HER2-targeting antibody-drug conjugates (ADC) have gained market approval for the treatment of HER2-expressing metastasis. Promising responses have been reported with the new generation of ADCs in patients who do not respond well to other HER2-targeting therapeutics. However, these ADCs still face challenges of resistance and/or severe adverse effects associated with their particular payload toxins. Eribulin, a therapeutic agent for the treatment of metastatic breast cancer and liposarcoma, is a new choice of ADC payload with a distinct mechanism of action and safety profile. METHODS: We've generated a novel HER2-tageting eribulin-containing ADC, BB-1701. The potency of BB-1701 was tested in vitro and in vivo against cancer cells where HER2-expressing levels vary in a large range. Bystander killing effect and toxin-induced immunogenic cell death (ICD) of BB-1701 were also tested. RESULTS: In comparison with HER2-targeting ADCs with DM1 and Dxd payload, eribulin-containing ADC demonstrated higher in vitro cytotoxicity in HER2-low cancer cell lines. BB-1701 also effectively suppressed tumors in models resistant to DM1 or Dxd containing ADCs. Mode of action studies showed that BB-1701 had a significant bystander effect on HER2-null cells adjacent to HER2-high cells. In addition, BB-1701 treatment induced ICD. Repeated doses of BB-1701 in nonhuman primates showed favorable pharmacokinetics and safety profiles at the intended clinical dosage, route of administration, and schedule. CONCLUSIONS: The preclinical data support the test of BB-1701 in patients with various HER2-expressing cancers, including those resistant to other HER2-targeting ADCs. A phase I clinical trial of BB-1701 (NCT04257110) in patients is currently underway.

Safety profiling of technical lignins originating from various bioresources and conversion processes.

In this work, a set of eight technical lignin samples from various botanical origins and production processes were characterized for their chemical composition, higher heating value, size distribution, dust explosion sensitivity and severity, thermal hazard characteristics and biodegradability, in further support of their sustainable use. More specifically, safety-focused parameters have been assessed in terms of consistency with relating physico-chemical properties determined for the whole set of technical lignins. The results emphasized the heterogeneity and variability of technical lignins and the subsequent need for a comprehensive characterization of new lignin feedstocks arising from novel biorefineries. Indeed, significant differences were revealed between the samples in terms of hazards sensitivity. This first comparative physico-chemical safety profiling of technical lignins could be useful for the hazard analysis and the safe design of the facilities associated with large scale valorisation of biomass residues such as lignins, targeting "zero waste" sustainable conversion of bioresources.

Remimazolam has similar anesthetic effect and superior safety compared to propofol in elderly patients: A meta-analysis of randomized controlled trials.

BACKGROUND: The superiority between remimazolam and propofol for anesthesia is controversial in elderly patients (≥60 years). This meta-analysis aimed to systematically compare anesthetic effect and safety profile between remimazolam and propofol in elderly patients under any surgery. METHODS: Cochrane Library, Web of Science, and PubMed were searched until December 25, 2023 for relevant randomized controlled trials. RESULTS: Ten studies with 806 patients receiving remimazolam (experimental group) and 813 patients receiving propofol (control group) were included. Time to loss of consciousness [standard mean difference (SMD) (95% confidence interval (CI): 1.347 (-0.362, 3.055), p = 0.122] and recovery time [SMD (95% CI): -0.022 (-0.300, 0.257), p = 0.879] were similar between experimental and control groups. Mean arterial pressure at baseline minus 1 min after induction [SMD (95% CI): -1.800 (-3.250, -0.349), p = 0.015], heart rate at baseline minus 1 min after induction [SMD (95% CI): -1.041 (-1.537, -0.545), p < 0.001], incidences of hypoxemia [relative risk (RR) (95% CI): 0.247 (0.138, 0.444), p < 0.001], respiratory depression [RR (95% CI): 0.458 (0.300, 0.700), p < 0.001], bradycardia [RR (95% CI): 0.409 (0.176, 0.954), p = 0.043], hypotension [RR (95% CI): 0.415 (0.241, 0.714), p = 0.007], and injection pain [RR (95% CI): 0.172 (0.113, 0.263), p < 0.001] were lower in the experimental group compared to the control group. Postoperative nausea and vomiting was not different between groups [RR (95% CI): 1.194 (0.829, 1.718), p = 0.341]. Moreover, this meta-analysis displayed a low risk of bias, minimal publication bias, and good robustness. CONCLUSION: Remimazolam shows comparative anesthetic effect and better safety profile than propofol in elderly patients under any surgery.

Adjuvant Atezolizumab in Patients with Sarcomatoid Renal Cell Carcinoma: A Prespecified Subgroup Analysis of IMmotion010.

Patients with sarcomatoid renal cell carcinoma (sRCC) have a poor prognosis. In the randomised, double-blind phase 3 IMmotion010 trial (NCT03024996), adjuvant atezolizumab did not demonstrate a disease-free survival (DFS) benefit versus placebo in the overall population of patients with locoregional renal cell carcinoma with an increased risk of recurrence following surgery. This prespecified subgroup analysis of efficacy and safety was completed in 104 patients with sRCC. Baseline characteristics were similar between treatment arms. At a median follow-up of 45 mo, the median DFS was not evaluable (NE; 95% confidence interval [CI], 12 mo-NE) in the atezolizumab arm (n = 37) and 23 mo (95% CI, 11-NE) in the placebo arm (n = 66; hazard ratio 0.77 [95% CI, 0.44-1.4]). In the sRCC subgroup, grade 3/4 treatment-related adverse events (TRAEs) occurred in one patient (2.7%) in the atezolizumab arm and two patients (3.0%) in the placebo arm. By comparison, 54 of 353 patients (15%) and 16 of 317 patients (5.0%) with non-sarcomatoid histology reported grade 3/4 TRAEs in the respective arms. In conclusion, the difference in DFS was not statistically significant between adjuvant atezolizumab and placebo in patients with sRCC. The safety profile was similar between patients with sRCC and non-sRCC. PATIENT SUMMARY: Patients with a specific type of locoregional kidney cancer (tumours with sarcomatoid features) were treated with atezolizumab or placebo after surgery. Slightly more patients treated with atezolizumab lived longer without the disease getting worse than those treated with placebo, although this finding was not statistically significant. The side effects were similar to those seen in patients with other types of kidney cancer treated with atezolizumab in the same study (IMmotion010). In patients with sarcomatoid kidney cancer, atezolizumab was tolerable and may be more effective than placebo, but this requires further study.

Interleukin 23 versus interleukin 12/23 inhibitors on preventing incidental psoriatic arthritis in patients with psoriasis? A real-world comparison from the TriNetX Global Collaborative Network.

BACKGROUND: Managing psoriasis and its comorbidities, particularly psoriatic arthritis, often involves using IL-23 and IL-12/23 inhibitors. However, the comparative risk of these treatments still needs to be explored. OBJECTIVE: This study evaluates the risk of developing psoriatic arthritis in patients treated with IL23 inhibitors compared to IL-12/23 inhibitors. METHODS: This retrospective cohort study utilized data from the TriNetX, including adult patients diagnosed with psoriasis. Patients with IL-23 or IL-12/23 inhibitors treatment were included and propensity score matched. The primary outcome was the incidence of arthropathic psoriasis, analyzed using a Cox regression hazard model and Kaplan-Meier estimates. RESULTS: The study included matched cohorts of patients treated with IL-23 inhibitors (n=2,273) and IL-12/23 inhibitors (n=2,995). Cox regression analysis revealed no significant difference in the cumulative incidence of arthropathic psoriasis between the IL-23i and IL-12/23i cohorts (p = 0.812). Kaplan-Meier estimates confirmed similar cumulative incidences of arthropathic psoriasis in both cohorts over the study period. LIMITATION: Long-term follow-up studies are required to understand more of the effects of these interleukin inhibitors. CONCLUSION: No significant difference but a numerically lower risk of PsA in PsO patients treated with IL-23 inhibitors than with IL-12/23 inhibitors, underscoring their comparable efficacy in PsO management and follow-up.

ENDOLUNG trial. A phase 1/2 study of the Akt/mTOR inhibitor and autophagy inducer Ibrilatazar (ABTL0812) in combination with paclitaxel/carboplatin in patients with advanced/recurrent endometrial cancer.

BACKGROUND: Carboplatin and paclitaxel (CP) have been the standard of care for advanced/recurrent endometrial cancer (EC) for many years. However, this chemotherapy combination shows limited efficacy and recurrences often occur in less than 12 months. ABTL0812 is a novel drug that selectively kill cancer cells by cytotoxic autophagy and has shown anticancer efficacy in preclinical models of EC in combination with CP. METHODS: ENDOLUNG was an open-label, phase 1/2 clinical trial designed to determine the safety and efficacy of Ibrilatazar (ABTL0812) with CP in patients with advanced/recurrent EC and non-irradiable stage III and IV squamous non-small cell lung cancer (sq-NSCLC). The phase 1 part consisted of a 3 + 3 de-escalation design followed by an expansion cohort with 12 patients. The primary endpoint was safety. ABTL0812 starting dose was 1300 mg tid combined with carboplatin at area under the curve (AUC) 5 and paclitaxel at 175 mg/m2 both administered every 21 days for up to 8 cycles. The phase 2 part included a total of 51 patients. The primary endpoint was overall response rate (ORR) and the secondary endpoints included duration of response (DOR), progression-free survival (PFS) and overall survival (OS). RESULTS: During the phase 1 only one dose limiting toxicity (DLT), a grade 4 neutropenia, was observed in 1 out of 6 patients, thus no de-escalation was applied. One additional DLT, a grade 3 febrile neutropenia, was observed in the expansion cohort, thus the recommended phase 2 dose (RP2D) for ABTL0812 was established at 1300 mg tid. Most frequent hematological adverse events (AE) of the combination were neutropenia (52.9%), anemia (37.3%) and thrombocytopenia (19.6%). Nausea (66.7%), asthenia (66.7%), diarrhea (54.9%) and vomiting (54.9%) were the most frequent non-hematological adverse events (AEs). The combination of ABTL0812 plus CP showed an ORR of 65.8% (13.2% complete response and 52.6% partial response) with a median DOR of 7.4 months (95% CI: 6.3-10.8 months). Median PFS was 9.8 months (95% CI: 6.6-10.6) and median OS 23.6 months (95% CI 6.4-ND). Pharmacokinetic parameters were compatible with target engagement observed in preclinical studies, and blood pharmacodynamic biomarkers indicated sustained target regulation during, at least, 28 days after starting the treatment. CONCLUSIONS: This study suggests that the combination of ABTL0812 with CP is safe and feasible with an encouraging activity in patients with advanced/recurrent EC. Our data warrant further confirmation in prospective randomized trials. TRIAL REGISTRATION: EU Clinical Trial Register, EudraCT number 2016-001352-21 and National Clinical Trials Number, NCT03366480. Registration on 19 September 2016.

Assessment of the Safety Profile of Chimeric Marker Vaccine against Classical Swine Fever: Reversion to Virulence Study.

Chimeric marker vaccine candidates, vGPE-/PAPeV Erns and vGPE-/PhoPeV Erns, have been generated and their efficacy and capability to differentiate infected from vaccinated animals were confirmed in previous studies. The safety profile of the two chimeric marker vaccine candidates, particularly in the potential reversion to virulence, was evaluated. Each virus was administered to pigs with a dose equivalent to the vaccination dose, and pooled tonsil homogenates were subsequently inoculated into further pigs. Chimeric virus vGPE-/PAPeV Erns displayed the most substantial attenuation, achieving this within only two passages, whereas vGPE-/PhoPeV Erns was detectable until the third passage and disappeared entirely by the fourth passage. The vGPE- strain, assessed alongside, consistently exhibited stable virus recovery across each passage without any signs of increased virulence in pigs. In vitro assays revealed that the type I interferon-inducing capacity of vGPE-/PAPeV Erns was significantly higher than that of vGPE-/PhoPeV Erns and vGPE-. In conclusion, the safety profile of the two chimeric marker vaccine candidates was affirmed. Further research is essential to ensure the stability of their attenuation and safety in diverse pig populations.

Evaluating the safety profile of semaglutide: an updated meta-analysis.

BACKGROUND: Semaglutide is increasingly used in the management of type 2 diabetes mellitus and obesity. Ensuring the safety of this medication is crucial for its clinical use. This meta-analysis evaluates the safety profile of semaglutide across patient populations and treatment durations. METHODS: Randomized controlled trials assessing the safety of semaglutide vs. placebo, with specified treatment durations were identified. The primary outcome was occurrence of any cardiovascular adverse events. Secondary outcomes included sudden cardiac death, adverse events leading to death, adverse events, gastrointestinal side effects, occurrence of hypoglycemia, and new-onset neoplasm. RESULTS: A total of 23 studies met the inclusion criteria with a combined sample size of 57,911 participants. The meta-analysis revealed that the adverse event associated with semaglutide is gastrointestinal in nature (nausea and vomiting). No significant differences were observed between semaglutide and comparator groups. CONCLUSION: Semaglutide appears to have a favorable safety profile across diverse patient populations and treatment durations, supporting its continued use in the management of type 2 diabetes mellitus and obesity. It is generally well-tolerated, with a low incidence of adverse events. Clinicians should be aware of these findings and monitor patients accordingly. Further long-term studies are warranted to assess the safety of semaglutide in clinical practice.

Atomoxetine: toxicological aspects of a new treatment for Attention Deficit Hyperactivity Disorder in Brazil.

Atomoxetine is a drug widely used for the treatment of the attention deficit hyperactivity disorder (ADHD) with reduced risk of adverse motor reactions and chemical dependence. However, the pharmacokinetics characteristics as well as the toxicological risk of atomoxetine deserves further investigation to comprehensively analyze the therapeutic and safety aspects of this drug. This study aimed to predict the physicochemical profile and medicinal chemistry characteristics of atomoxetine, alongside its pharmacokinetic properties-namely absorption, distribution, metabolism, and excretion-as well as its toxicology (ADMET) potential through the utilization of web-based in silico tools. This research emphasizes predicted physicochemical, medicinal chemistry, and absorption parameters of atomoxetine that could influence the efficacy and safety of this drug for ADHD treatment. Additionally, atomoxetine also presents noteworthy predicted risks of hepatotoxicity, cardiotoxicity, neurotoxicity, nephrotoxicity, respiratory system toxicity, skin toxicity, and carcinogenicity. These findings underscore the necessity for further assessments of atomoxetine's safety profile, particularly considering different patient populations and durations of drug treatment. The data reported here from in silico predictions suggest that closer monitoring is warranted when atomoxetine is administered to patients with ADHD. Moreover, controlled studies detailing reliable protocols for personalized dosing, considering the multifactorial variability in metabolism efficiency and toxicological potential, would enable a more comprehensive assessment of atomoxetine's safety profile.

The influence of low-dose s-ketamine on postoperative delirium and cognitive function in older adults undergoing thoracic surgery.

BACKGROUND: Postoperative delirium (POD) and cognitive dysfunction (POCD) are common complications following thoracic surgery, particularly in patients aged 65 years and above. These complications can significantly affect recovery and increase healthcare costs. This study investigates the effects of low-dose S-ketamine on reducing POD and POCD in this patient demographic. METHODS: In this retrospective cohort study, medical records of patients aged ≥ 65 years who underwent elective thoracic surgery from January 2019 to August 2023 were reviewed. Patients were categorized into S-ketamine and Control groups based on intraoperative S-ketamine exposure. POD was assessed using the Confusion Assessment Method (CAM), while cognitive function was evaluated using the Montreal Cognitive Assessment (MoCA) at baseline, 1 week, 1 month, and 6 months post-surgery. Intraoperative and postoperative parameters, including hemodynamic stability, blood loss, pain scores, and ICU stay length, were also recorded. RESULTS: The study comprised 140 participants, with 70 in each group. The S-ketamine group demonstrated a significantly lower incidence of POD at 7 days post-surgery (12.0% vs. 26.7%, P < 0.001), and reduced POCD at 1 month (18.7% vs. 36.0%, P < 0.05) and 6 months (10.7% vs. 21.3%, P < 0.05). The Ketamine group had a significantly higher median MoCA score compared to the Control group both at 1 month (P = 0.021) and 6 months (P = 0.007). Adverse events, such as infection, bleeding, and respiratory failure, showed no significant differences between the groups, suggesting a safe profile for S-ketamine. CONCLUSION: Administering low-dose S-ketamine during thoracic surgery in patients aged 65 years and above significantly reduces the incidence of POD and POCD, highlighting its neuroprotective potential. These findings advocate for the inclusion of S-ketamine in anesthetic protocols to improve postoperative outcomes and reduce healthcare costs in this patient population.

First­line programmed cell death 1 inhibitor plus chemotherapy vs. standard treatment in patients with recurrent or metastatic oral squamous cell carcinoma: A retrospective cohort study.

Programmed cell death 1 (PD-1) inhibitor revives the killing effect of immune cells to prevent tumor progression. The present study aimed to evaluate the efficacy and safety of first-line PD-1 inhibitor + chemotherapy vs. standard treatment in recurrent or metastatic (R/M) oral squamous cell carcinoma (OSCC). A total of 51 patients with R/M OSCC were reviewed and divided into the PD-1 inhibitor + chemotherapy (n=21) and standard treatment (n=30) groups based on their actual treatments. The results of the present study demonstrated that the objective response rate (52.4 vs. 36.7%, P=0.265) and disease control rate (81.0 vs. 70.0%, P=0.377) were numerically elevated in the PD-1 inhibitor + chemotherapy group compared with those in the standard treatment group; however, the results did not reach statistical significance. The progression-free survival (PFS) was numerically increased (without statistical significance) in the PD-1 inhibitor + chemotherapy group compared with that of the standard treatment group (P=0.057). Specifically, the PD-1 inhibitor + chemotherapy group and the standard treatment group exhibited a median [95% confidence interval (CI)] PFS duration of 6.7 (1.6-11.8) and 5.2 (3.4-7.0) months, respectively. In addition, the PD-1 inhibitor + chemotherapy group demonstrated increased overall survival (OS) compared with that of the standard treatment group (P=0.032). Specifically, the PD-1 inhibitor + chemotherapy group and the standard treatment group exhibited a median (95% CI) OS duration of 18.3 (11.9-24.7) and 10.3 (7.9-12.7) months, respectively. Furthermore, multivariate Cox regression analysis indicated that PD-1 inhibitor + chemotherapy was independently associated with improved PFS [hazard ratio (HR)=0.308, P=0.002] and OS (HR=0.252, P=0.003). In addition, the incidence of grade 3-5 adverse events (AEs) was relatively low in both groups and the incidence of any grade of each AE was not significantly different between groups (all P>0.050). In conclusion, the first-line PD-1 inhibitor + chemotherapy group had improved efficacy and comparable safety compared with those of the standard treatment in patients with R/M OSCC.

Safety and Preliminary Effectiveness of Lateral Transiliac Sacroiliac Joint Fusion by Interventional Pain Physicians: A Retrospective Analysis.

Introduction: Minimally invasive sacroiliac (SI) joint fusion has become the mainstay treatment for chronic refractory sacroiliac joint dysfunction. Multiple procedures are now available including transfixing procedures with implants placed in the lateral or posterolateral transiliac trajectories, and intra-articular procedures with devices and/or allograft placed via a dorsal approach. To date, the published literature on the lateral approach has been primarily by surgeons. This retrospective chart review aims to evaluate the safety and preliminary effectiveness when the procedure is performed by physicians trained in interventional pain management. Methods: Retrospective analysis of patients who underwent lateral SI joint fusion using a lateral transiliac approach between December 2022 and September 2023 by a single physician. Data on demographics, perioperative details, complications, and postoperative outcomes were collected and analyzed. The study was reviewed by WCG IRB and received an exemption authorization. Results: Medical charts were reviewed for the first 49 consecutive cases performed. Mean (SD, range) age was 64 (11, 34-83), BMI was 32.5 (8.4), 59% were female, 35% were smokers, and 82% were on opioids at baseline. Mean (SD) operative time was 40 (11) minutes and all procedures were performed at an ambulatory surgery center under monitored anesthesia care. No device- or procedure-related complications occurred. Mean follow up was 175 days; Mean (SD) baseline reported pain was 9 (1.5) on a 0-10 numerical rating scale. At follow up, 88% of the patients reported ≥50% pain relief. Six patients who reported 0% relief suffer from multiple pain generators and are on long term opioids. Conclusion: Results of this single center experience support the safety of lateral SI joint fusion using a threaded implant when performed by interventional pain management physicians. However, further prospective studies with larger sample sizes and longer follow-ups are warranted to validate these findings.

The effectiveness and safety of clazosentan in treating aneurysmal subarachnoid hemorrhage: A systematic review and meta-analysis.

BACKGROUND: Aneurysmal subarachnoid hemorrhage (aSAH) is a severe event often complicated by cerebral vasospasm (CV). This study aimed to assess the efficacy and safety of clazosentan, an endothelin receptor antagonist, in reducing CV, delayed cerebral ischemia (DCI), and the need for rescue therapy in aSAH patients, while evaluating its impact on functional outcomes and mortality. METHODS: We conducted a literature search across multiple databases to identify relevant studies evaluating the effects of clazosentan in aSAH patients. Both cohort studies and randomized controlled trials (RCTs) were included. The primary outcomes were vasospasm incidence, moderate to severe vasospasm, DCI, and the need for rescue therapy. Secondary outcomes included functional outcomes, mortality, and adverse events. The data were pooled as Risk ratios (R/R) with 95 % confidence intervals (CI) using RevMan 5.4 software. RESULTS: A total of 11 studies, including 10 published and one unpublished, comprising 8,469 patients were included in the meta-analysis. Clazosentan significantly reduced the incidence of vasospasm (R/R = 0.49: 0.34-0.70), moderate to severe vasospasm (R/R = 0.53: 0.46-0.61), DCI (R/R = 0.70: 0.59-0.82), and the need for rescue therapy (R/R = 0.65: 0.52-0.83) compared to placebo. However, no significant improvement in functional outcomes or mortality rates was observed. Clazosentan was associated with increased rates of pulmonary adverse events (R/R = 1.89: 1.64-2.18), hypotension (R/R = 2.47: 1.79-3.42), and anemia (R/R = 1.49: 1.23-1.79) but no increased risk of hepatobiliary adverse events or cerebral hemorrhage. CONCLUSIONS: Clazosentan demonstrates efficacy in reducing vasospasm, moderate to severe vasospasm, DCI, and the need for rescue therapy in aSAH patients, but does not significantly improve functional outcomes or mortality rates. While associated with specific adverse events, clazosentan may be a valuable adjunctive therapy in the management of aSAH, particularly in a high-risk population for vasospasm.

The efficacy, safety, and beneficiary population of angiogenesis inhibitor apatinib plus chemotherapy in recurrent platinum-resistant ovarian cancer patients: A comparative cohort study.

AIM: Angiogenesis inhibitor apatinib targets vascular endothelial growth factor receptors and improves the outcomes of patients with gynecologic malignancy. This study aimed to evaluate the efficacy and safety of angiogenesis inhibitor apatinib plus chemotherapy in recurrent platinum-resistant ovarian cancer (RPR-OC) patients. METHODS: This study retrieved 67 RPR-OC patients who received apatinib plus chemotherapy or chemotherapy alone and divided them into apatinib + chemo (N = 30) and chemo alone (N = 37) groups according to the actual medication. RESULTS: Objective response rate (36.7% vs. 16.2%, p = 0.056) and disease control rate (80.0% vs. 59.5%, p = 0.072) showed an increased trend in apatinib + chemo group versus chemo alone group. The progression-free survival (PFS) (p = 0.010) and overall survival (OS) (p = 0.042) were prolonged in apatinib + chemo group versus chemo alone group. The median (95%confidence interval [CI]) PFS was 5.9 (5.5-6.3) months in apatinib + chemo group and 3.8 (2.0-5.6) months in chemo alone group. The median (95%CI) OS was 20.5 (16.5-24.5) months in apatinib + chemo group and 13.6 (8.6-18.6) months in chemo alone group. Apatinib plus chemotherapy was independently related with better PFS (hazard ratio [HR]: 0.354, p < 0.001) and OS (HR: 0.116, p < 0.001). Subgroup analyses indicated that patients with a more serious disease condition might benefit more from apatinib plus chemotherapy. No difference was found in adverse events of all grade or grade ≥3 between the two groups (all p > 0.05). CONCLUSION: Angiogenesis inhibitor apatinib plus chemotherapy shows better treatment efficacy than chemotherapy alone with controllable safety profile in RPR-OC patients.
