Efficacy and Safety of Vildagliptin and Remogliflozin as Add-on Therapy to Metformin in Patients of Type 2 Diabetes Mellitus: An open-label comparative study.

Objectives: This study aimed to evaluate the safety and efficacy of remogliflozin compared to vildagliptin as an add-on drug to metformin in type 2 diabetes mellitus (T2DM) treatment. Metformin is considered a first-line drug in T2DM. However, as the disease progresses with heightened insulin resistance and declining ß-cell function, the use of metformin alone is often inadequate to achieve optimum glucose levels. Methods: This prospective, randomised study was conducted at Maulana Azad Medical College and Associated Hospital in New Delhi, India, between February 2020 to January 2021. This study recruited 60 T2DM patients aged 35-70 years with glycated haemoglobin (HbA1c) >6.5% taking metformin at a daily dosage of 1,500-3,000 mg for ≥3 months. Patients were randomly assigned in a 1:1 ratio to receive either vildagliptin (50 mg) or remogliflozin (100 mg) twice daily for 90 days. The primary endpoint was a change in HbA1c levels from baseline to the end of 90 days whereas secondary endpoints were changes in lipid profile and weight. Results: The decrement in mean HbA1c levels was significantly higher in the remogliflozin group than in the vildagliptin group (-8.1% versus -2.4%; P <0.001). In addition, more significant weight loss was found in remogliflozin-treated patients (-5.2% versus -0.6%; P <0.01). Both treatments were well tolerated throughout the study. Conclusion: Compared to vildagliptin, remoglilflozin was significantly more effective in glycaemic control and weight loss in patients with T2DM and can therefore be considered as an add-on drug in T2DM not adequately controlled by metformin monotherapy.

Minocycline in the eradication of Helicobacter pylori infection: A systematic review and meta-analysis.

BACKGROUND: Difficulty in obtaining tetracycline, increased adverse reactions, and relatively complicated medication methods have limited the clinical application of the classic bismuth quadruple therapy. Therefore, the search for new alternative drugs has become one of the research hotspots. In recent years, minocycline, as a semisynthetic tetracycline, has demonstrated good potential for eradicating Helicobacter pylori (H. pylori) infection, but the systematic evaluation of its role remains lacking. AIM: To explore the efficacy, safety, and compliance of minocycline in eradicating H. pylori infection. METHODS: We comprehensively retrieved the electronic databases of PubMed, Embase, Web of Science, China National Knowledge Infrastructure, SinoMed, and Wanfang database as of October 30, 2023, and finally included 22 research reports on H. pylori eradication with minocycline-containing regimens as per the inclusion and exclusion criteria. The eradication rates of H. pylori were calculated using a fixed or a random effect model, and the heterogeneity and publication bias of the studies were measured. RESULTS: The single-arm meta-analysis revealed that the minocycline-containing regimens achieved good overall H. pylori eradication rates, reaching 82.3% [95% confidence interval (CI): 79.7%-85.1%] in the intention-to-treat analysis and 90.0% (95%CI: 87.7%-92.4%) in the per-protocol analysis. The overall safety and compliance of the minocycline-containing regimens were good, demonstrating an overall incidence of adverse reactions of 36.5% (95%CI: 31.5%-42.2%). Further by traditional meta-analysis, the results showed that the minocycline-containing regimens were not statistically different from other commonly used eradication regimens in eradication rate and incidence of adverse effects. Most of the adverse reactions were mild to moderate and well-tolerated, and dizziness was relatively prominent in the minocycline-containing regimens (16%). CONCLUSION: The minocycline-containing regimens demonstrated good efficacy, safety, and compliance in H. pylori eradication. Minocycline has good potential to replace tetracycline for eradicating H. pylori infection.

A randomized controlled double-blinded split-face prospective clinical trial to assess the efficacy, safety, and tolerability of a novel 3-step routine compared to benzoyl peroxide for the treatment of mild to moderate acne vulgaris.

Adult acne vulgaris affects up to 43-51% of individuals. While there are numerous treatment options for acne including topical, oral, and energy-based approaches, benzoyl peroxide (BPO) is a popular over the counter (OTC) treatment. Although BPO monotherapy has a long history of efficacy and safety, it suffers from several disadvantages, most notably, skin irritation, particularly for treatment naïve patients. In this prospective, randomized, controlled, split-face study, we evaluated the comparative efficacy, safety, and tolerability of a novel 3-step azelaic acid, salicylic acid, and graduated retinol regimen versus a common OTC BPO-based regimen over 12 weeks. A total of 37 adult subjects with self-reported mild to moderate acne vulgaris were recruited. A total of 21 subjects underwent a 2-week washout period and completed the full study with 3 dropping out due to product irritation from the BPO routine, and 13 being lost to follow-up. Detailed tolerability surveys were conducted at Week 4. Additional surveys on tolerability and product preferences were collected monthly, at Week 4, Week 8, and Week 12. A blinded board-certified dermatologist objectively scored the presence and type of acne lesions (open or closed comedones, papules, pustules, nodules, and cysts) at baseline, Week 4, Week 8, and Week 12. Patients photographed themselves and uploaded the images using personal mobile phones. Detailed Week 4 survey results showed across 25 domains of user-assessed product performance, the novel routine outperformed the BPO routine in 19 (76%) which included domains in preference (e.g. "I would use this in the future) and performance ("my skin improved" and "helped my acne clear up faster"). Users of the novel routine reported less facial redness, itching, and burning, though differences did not reach statistical significance. In terms of efficacy, both products performed similarly, reducing total acne lesions by 36% (novel routine) and 40% (BPO routine) by Week 12. Overall, accounting for user preferences and tolerability the novel routine was more preferred than the BPO routine in 79% of domains (22/28). Differences in objective acne lesion reduction were not statistically significant (p = 0.97). In a randomized split-face study, a 3-step azelaic acid, salicylic acid, and graduated retinol regimen delivered similar acne lesion reduction, fewer user dropouts, greater user tolerability, and higher use preference compared to a 3-step BPO routine based in a cohort of participants with mild-to-moderate acne vulgaris.

Biogated mesoporous silica nanoagents for inhibition of cell migration and combined cancer therapy.

Migration is an initial step in tumor expansion and metastasis; suppressing cellular migration is beneficial to cancer therapy. Herein, we designed a novel biogated nanoagents that integrated the migration inhibitory factor into the mesoporous silica nanoparticle (MSN) drug delivery nanosystem to realize cell migratory inhibition and synergistic treatment. Antisense oligonucleotides (Anti) of microRNA-330-3p, which is positively related with cancer cell proliferation, migration, invasion, and angiogenesis, not only acted as the locker for blocking drugs but also acted as the inhibitory factor for suppressing migration via gene therapy. Synergistic with gene therapy, the biogated nanoagents (termed as MSNs-Gef-Anti) could achieve on-demand drug release based on the intracellular stimulus-recognition and effectively kill tumor cells. Experimental results synchronously demonstrated that the migration suppression ability of MSNs-Gef-Anti nanoagents (nearly 30%) significantly contributed to cancer therapy, and the lethality rate of the non-small-cell lung cancer was up to 70%. This strategy opens avenues for realizing efficacious cancer therapy and should provide an innovative way for pursuing the rational design of advanced nano-therapeutic platforms with the combination of cancer cell migratory inhibition.

Long-term effects of adjunctive eslicarbazepine acetate in adult Asian patients with refractory focal seizures: Post hoc analysis of a phase III trial.

A post hoc analysis of data from Asian patients included in the study BIA-2093-304 was conducted to evaluate the long-term safety/tolerability and efficacy of adjunctive eslicarbazepine acetate (ESL) in adult Asian patients with refractory focal seizures. Part I was a randomized controlled trial, in which patients received ESL (800 or 1200 mg once daily [QD]) or placebo, assessed over a 12-week maintenance period. Patients completing Part I could enter two open-label extension periods (Part II, 1 year; Part III, ≥2 years), during which all received ESL (400-1600 mg QD). Safety/tolerability was assessed by evaluating treatment-emergent adverse events (TEAEs). Efficacy assessments included responder and seizure freedom rates. The safety population included 125, 92, and 23 Asian patients in Parts I, II, and III, respectively. Incidence of ESL-related TEAEs was 61.3%, 45.7%, and 17.4% during Parts I, II, and III, respectively. ESL-related TEAEs (most commonly, dizziness, somnolence, and headache) were consistent with ESL's known safety profile. During Part I, responder rates were higher with ESL 800 (41.7%) and 1200 mg QD (44.4%) versus placebo (32.6%), although not statistically significant. Seizure freedom rates with ESL 800 (5.5%) and 1200 mg QD (11.1%) were also higher versus placebo (0%) (p < 0.05 for ESL 1200 mg QD versus placebo). At the end of Part II, responder and seizure freedom rates were 60.3% and 14.7%, respectively. In summary, adult Asian patients with refractory focal seizures were responsive to treatment with ESL as adjunctive therapy and generally showed treatment tolerance well for up to 3 years. No new/unexpected safety findings were observed.

Combination treatment of inflammatory bowel disease: Present status and future perspectives.

The treatment of patients with inflammatory bowel disease (IBD), especially those with severe or refractory disease, represents an important challenge for the clinical gastroenterologist. It seems to be no exaggeration to say that in these patients, not only the scientific background of the gastroenterologist is tested, but also the abundance of "gifts" that he should possess (insight, intuition, determination, ability to take initiative, etc.) for the successful outcome of the treatment. In daily clinical practice, depending on the severity of the attack, IBD is treated with one or a combination of two or more pharmaceutical agents. These combinations include not only the first-line drugs (e.g., mesalazine, corticosteroids, antibiotics, etc) but also second- and third-line drugs (immunosuppressants and biologic agents). It is a fact that despite the significant therapeutic advances there is still a significant percentage of patients who do not satisfactorily respond to the treatment applied. Therefore, a part of these patients are going to surgery. In recent years, several small-size clinical studies, reviews, and case reports have been published combining not only biological agents with other drugs (e.g., immunosuppressants or corticosteroids) but also the combination of two biological agents simultaneously, especially in severe cases. In our opinion, it is at least a strange (and largely unexplained) fact that we often use combinations of drugs in a given patient although studies comparing the simultaneous administration of two or more drugs with monotherapy are very few. As mentioned above, there is a timid tendency in the literature to combine two biological agents in severe cases unresponsive to the applied treatment or patients with severe extraintestinal manifestations. The appropriate dosage, the duration of the administration, the suitable timing for checking the clinical and laboratory outcome, as well as the treatment side-effects, should be the subject of intense clinical research shortly. In this editorial, we attempt to summarize the existing data regarding the already applied combination therapies and to humbly formulate thoughts and suggestions for the future application of the combination treatment of biological agents in a well-defined category of patients. We suggest that the application of biomarkers and artificial intelligence could help in establishing new forms of treatment using the available modern drugs in patients with IBD resistant to treatment.

First-line camrelizumab (a PD-1 inhibitor) plus apatinib (an VEGFR-2 inhibitor) and chemotherapy for advanced gastric cancer (SPACE): a phase 1 study.

Patients with advanced gastric cancer typically face a grim prognosis. This phase 1a (dose escalation) and phase 1b (dose expansion) study investigated safety and efficacy of first-line camrelizumab plus apatinib and chemotherapy for advanced gastric or gastroesophageal junction adenocarcinoma. The primary endpoints included maximum tolerated dose (MTD) in phase 1a and objective response rate (ORR) across phase 1a and 1b. Phase 1a tested three dose regimens of camrelizumab, apatinib, oxaliplatin, and S-1. Dose regimen 1: camrelizumab 200 mg on day 1, apatinib 250 mg every other day, oxaliplatin 100 mg/m² on day 1, and S-1 40 mg twice a day on days 1-14. Dose regimen 2: same as dose regimen 1, but oxaliplatin 130 mg/m². Dose regimen 3: same as dose regimen 2, but apatinib 250 mg daily. Thirty-four patients were included (9 in phase 1a, 25 in phase 1b). No dose-limiting toxicities occurred so no MTD was identified. Dose 3 was set for the recommended phase 2 doses and administered in phase 1b. The confirmed ORR was 76.5% (95% CI 58.8-89.3). The median progression-free survival was 8.4 months (95% CI 5.9-not evaluable [NE]), and the median overall survival (OS) was not mature (11.6-NE). Ten patients underwent surgery after treatment and the multidisciplinary team evaluation. Among 24 patients without surgery, the median OS was 19.6 months (7.8-NE). Eighteen patients (52.9%) developed grade ≥ 3 treatment-emergent adverse events. Camrelizumab plus apatinib and chemotherapy showed favorable clinical outcomes and manageable safety for untreated advanced gastric cancer (ChiCTR2000034109).

Combined Dexamethasone and Dexmedetomidine as Adjuncts to Popliteal and Saphenous Nerve Blocks in Patients Undergoing Surgery of the Foot or Ankle: A Randomized, Blinded, Placebo-controlled Clinical Trial.

BACKGROUND: Both dexamethasone and dexmedetomidine increase the duration of analgesia of peripheral nerve blocks. The authors hypothesized that combined intravenous dexamethasone and intravenous dexmedetomidine would result in a greater duration of analgesia when compared with intravenous dexamethasone alone and placebo. METHODS: The authors randomly allocated participants undergoing surgery of the foot or ankle under general anesthesia and with a combined popliteal (sciatic) and saphenous nerve block to a combination of 12 mg dexamethasone and 1 µg/kg dexmedetomidine, 12 mg dexamethasone, or placebo (saline). The primary outcome was the duration of analgesia measured as the time from block performance until the first sensation of pain in the surgical area as reported by the participant. The authors predefined a 33% difference in the duration of analgesia as clinically relevant. RESULTS: A total of 120 participants from two centers were randomized and 119 analyzed for the primary outcome. The median [interquartile range] duration of analgesia was 1,572 min [1,259 to 1,715] with combined dexamethasone and dexmedetomidine, 1,400 min [1,133 to 1,750] with dexamethasone alone, and 870 min [748 to 1,138] with placebo. Compared with placebo, the duration was greater with combined dexamethasone and dexmedetomidine (difference, 564 min; 98.33% CI, 301 to 794; P < 0.001) and with dexamethasone (difference, 489 min; 98.33% CI, 265 to 706; P < 0.001). The prolongations exceeded the authors' predefined clinically relevant difference. The duration was similar when combined dexamethasone and dexmedetomidine was compared with dexamethasone alone (difference, 61 min; 98.33% CI, -222 to 331; P = 0.614). CONCLUSIONS: Dexamethasone with or without dexmedetomidine increased the duration of analgesia in patients undergoing surgery of the foot or ankle with a popliteal (sciatic) and saphenous nerve block. Combined dexamethasone and dexmedetomidine did not increase the duration of analgesia when compared with dexamethasone.

Effectiveness analysis of three-drug combination therapies for refractory focal epilepsy.

Selecting appropriate antiseizure medications (ASMs) for combination therapy in patients with drug-resistant epilepsy (DRE) is a complex task that requires an empirical approach, especially in patients receiving polytherapy. We aimed to analyze the effectiveness of various three-drug combinations in a group of patients with DRE under real-world conditions. This single-center, longitudinal observational study investigated patients with drug-resistant focal epilepsy who received three-drug regimens in the outpatient clinic of Tongji Hospital from September 2019 to December 2022. The effectiveness of each triple regimen was evaluated by the seizure-free rate and within-patient ratio of the seizure frequency (a seizure frequency ratio [SFR]<1 indicated superior efficacy). The independent t-test or Mann-Whitney U test was used for effectiveness analysis, and P values were adjusted by the Benjamini-Hochberg method for multiple comparisons. A total of 511 triple trials comprising 76 different regimens were conducted among 323 enrolled patients. Among these triple regimens, lamotrigine (LTG)/valproic acid (VPA)/topiramate (TPM) was the most frequently prescribed (29.4%, n â€‹= â€‹95). At the last clinical visit, 14.9% (n â€‹= â€‹48) of patients achieved seizure freedom after receiving triple therapy. LTG/VPA/TPM and LTG/VPA/levetiracetam (LEV) exhibited the highest seizure-free rates at 17.9% and 12.8%, respectively. These two regimens also had significantly lower median SFRs of 0.48 (interquartile range [IQR], 0.17-0.85; adjusted P â€‹< â€‹0.001) and 0.63 (IQR, 0.21-1.04; adjusted P â€‹< â€‹0.01), respectively. LTG/VPA/perampanel (PER) was another promising regimen that showed marginal effectiveness (median SFR â€‹= â€‹0.67; adjusted P â€‹= â€‹0.053). LTG/VPA/phenobarbital had the highest incidence of regimen-specific side effects (40.0%, 4/10), while the incidence of side effects from LTG/VPA/LEV was minimal (5.1%, 2/39). In conclusion, LTG/VPA/TPM and LTG/VPA/LEV exhibited superior efficacy and good tolerability in treating patients with DRE. Our results provide preliminary insights into the selection of ASMs for three-drug combination therapies in this clinically challenging population.

Furosemide to lower antenatal severe hypertension: a randomized placebo-controlled trial.

BACKGROUND: Hypertensive disorders of pregnancy are a leading cause of perinatal morbidity, and timely treatment of severely elevated blood pressure is recommended to prevent serious sequelae. In acute hypertension marked by increased blood volume, it is unknown whether diuretics used as an adjunct to antihypertensive medications lead to more effective blood pressure control. OBJECTIVE: This study aimed to evaluate whether the addition of intravenous furosemide to first-line antihypertensive agents reduces systolic blood pressure in acute-onset, severe antenatal hypertension with wide (≥60 mm Hg) pulse pressure. STUDY DESIGN: In this double-blinded randomized trial, participants received 40 mg of intravenous furosemide or placebo in addition to a first-line antihypertensive agent. The primary outcome was mean systolic blood pressure during the first hour after intervention. Secondary outcomes included corresponding diastolic blood pressure; systolic blood pressure, diastolic blood pressure, and pulse pressure at 2 hours after intervention; total reduction from qualifying blood pressure; duration of blood pressure control; need for additional antihypertensive doses within 1 hour; and electrolytes and urine output. A sample size of 35 participants per group was planned to detect a 15-mm Hg difference in blood pressure. RESULTS: Between January 2021 and March 2022, 65 individuals were randomized: 33 to furosemide and 32 to placebo. Baseline characteristics were similar between the groups. There was no difference in the primary outcome of mean 1-hour systolic blood pressure (147 [14.8] vs 152 [13.8] mm Hg; P=.200). We found a reduction in 2-hour systolic blood pressure (139 [18.5] vs 154 [18.4] mm Hg; P=.007) and a decrease in 2-hour pulse pressure (55 [12.5] vs 67 [15.1]; P=.003) in the furosemide group. Subgroup analysis according to hypertension type showed a significant reduction in 2-hour systolic blood pressure and 2-hour pulse pressure among patients with new-onset hypertension, but not among those with preexisting hypertension. Urine output was greater in the furosemide group, with no difference in electrolytes and creatinine before and after intervention. CONCLUSION: Intravenous furosemide in conjunction with a first-line antihypertensive agent did not significantly reduce systolic blood pressure in the first hour after administration. However, both systolic blood pressure and pulse pressure at 2 hours were decreased in the furosemide group. These findings suggest that a 1-time dose of intravenous furosemide is a reasonable adjunct to achieve blood pressure control, particularly in patients in whom increased volume is suspected.

Pharmacodynamic rationale for the choice of antiseizure medications in the paediatric population.

In the landscape of paediatric epilepsy treatment, over 20 anti-seizure medications (ASMs) have gained approval from Drug Regulatory Agencies, each delineating clear indications. However, the complexity of managing drug-resistant epilepsy often necessitates the concurrent use of multiple medications. This therapeutic challenge highlights a notable gap: the absence of standardized guidelines, compelling clinicians to rely on empirical clinical experience when selecting combination therapies. This comprehensive review aims to explore current evidence elucidating the preferential utilization of specific ASMs or their combinations, with a primary emphasis on pharmacodynamic considerations. The fundamental objective underlying rational polytherapy is the strategic combination of medications, harnessing diverse mechanisms of action to optimize efficacy while mitigating shared side effects. Moreover, the intricate interplay between epilepsy and comorbidities partly may influence the treatment selection process. Despite advancements, unresolved queries persist, notably concerning the mechanisms underpinning drug resistance and the paradoxical exacerbation of seizures. By synthesizing existing evidence and addressing pertinent unresolved issues, this review aims to contribute to the evolving landscape of paediatric epilepsy treatment strategies, paving the way for more informed and efficacious therapeutic interventions.

Assessing effectiveness of adding niosomal atorvastatin 1% ointment to topical calcineurin inhibitor treatment in non-segmental vitiligo.

BACKGROUND: Treatment of vitiligo is still a big challenge for dermatologists. The efficacy of statins in the treatment of vitiligo is controversial. AIM AND OBJECTIVE: We studied possible therapeutic effect of topical 1% niosomal atorvastatin ointment combined with topical 0.1% tacrolimus in treatment of non-segmental vitiligo. METHODS: This is a triple blind, pilot, randomized placebo-controlled trial (RCT) that was performed in dermatology clinic. All the patients used topical 0.1% tacrolimus cream twice daily (BD). Moreover, the intervention group participants used topical 1% niosomal atorvastatin ointment, and control group participants were prescribed placebo ointment, BD. Patients were evaluated using vitiligo area surface index (VASI) score and patients' satisfaction at baseline and after 3 months treatment. RESULTS: The mean patient satisfaction in the intervention and control groups were 5 ± 1.4 and 3.5 ± 1.9; the difference between groups was not statistically significant (p = 0.9). We found statistically significant difference in VASI score before and after treatment in both intervention and control groups (p = 0.01 and p = 0.03, respectively). However, comparison of the VASI score between groups was not statistically significant (p = 0.62). We also found no significant correlation between VASI score and other variables. CONCLUSION: The result of this study indicates that adding of niosomal atorvastatin 1% ointment to topical calcineurin inhibitor has no additional effect on non-segmental type of vitiligo. Further large studies with different combinations are recommended before any conclusive result can be concluded on efficacy of statins in vitiligo.

Ceftazidime-avibactam in the treatment of bacteremia due to carbapenem-resistant gram-negative bacteria in hematological patients: Experience in a single center.

INTRODUCTION: Limited experience exists with ceftazidime-avibactam (CAZ-AVI) in treating bacteremia caused by carbapenem-resistant Enterobacterales (CRE) and Pseudomonas aeruginosa (CRPA) in hematological patients. METHODS: We performed a single-center, retrospective, observational study including patients who received CAZ-AVI for bacteremia due to CRE or CRPA between 2018 and 2022. The primary outcome was 30-day survival. We conducted a multivariable analysis to identify predictors of survival. RESULTS: 56 patients were included and 57 (41 CRE and 16 CRPA) strains were isolated. 35 strains produced carbapenemase, including 25 metallo-beta-lactamase (MBL) and 10 serine-beta-lactamase. 48 patients (85.7 %) received combination therapy. All patients with MBL-CRE bacteremia (n = 24) received combination therapy with aztreonam (AZT). The susceptibility rates to CAZ-AVI were only 26.8 % (11/41) in CRE and 80.0 % (8/10) in CRPA. The 30-day survival rates were 85.0 % (34/40) in the CRE group and 81.3 % (13/16) in the CRPA group. In patients with MBL-CRE bacteremia, the 30-day survival was as high as 91.7 % (22/24) due to combination with AZT. Ceftazidime did not influence the activity of aztreonam-avibactam against MBL-CRE in-vitro. Multivariable cox analysis revealed neutropenia >14 days (P = 0.002, HR: 34.483, 95%CI: 3.846-333.333) and a higher Pitt bacteremia score (P = 0.005, HR: 2.074, 95%CI: 1.253-3.436) were risk factors for 30-day survival. CONCLUSIONS: CAZ-AVI is highly effective in treating bacteremia due to CRPA and serine-beta-lactamase CRE. The combination of avibactam with AZT is highly effective in treating bacteremia due to AZT-resistant MBL producers.

[Chinese expert consensus on intra-arterial drug and combined drug administration for primary hepatocellular carcinoma].

Transarterial interventional therapy is one of the most widely used treatment methods in patients with primary hepatocellular carcinoma. With the progress in interventional technology and the use of new drugs, transarterial interventional therapy has achieved favorable results in the treatment of primary hepatocellular carcinoma and has become the first choice non-surgical treatment for advanced liver cancer. However, at present, there are great differences in the drugs used in transarterial interventional treatment and the combined application of other drugs among centers, and there is no uniform consensus or guideline. Based on the latest research data and clinical practice experience, as well as the characteristics of Chinese patients, the Specialist Group of Interventional Drugs, Interventionalists Branch of the Chinese Medical Doctor Association was organized to formulate the Chinese expert consensus on intra-arterial drug and combined drug administration for primary hepatocellular carcinoma. The purpose of this consensus is to explore the efficacy and safety of drugs and drug combinations related to intra-arterial interventional therapy, the use of drugs in special populations, the management of adverse reactions, and adjuvant drugs to provide a reference for clinical practice.

Polylactic acid based polymeric nanoparticle mediated co-delivery of navitoclax and decitabine for cancer therapy.

Combination chemotherapy with systemic administration of drugs in their free form can be challenging due to non-synchronized pharmacokinetics and sub-optimal tumor accumulation. The present study investigates a PLA-based block copolymeric nanocarrier for the co-delivery of navitoclax and decitabine (NAV/DCB NPs) for combination cancer therapy. NAV/DCB NPs exhibited potent in vitro synergistic cytotoxicity in both acute myeloid leukemia and breast cancer cell lines. Biodistribution studies of NAV/DCB NPs in tumor bearing mice, showed significant drug accumulation in tumor tissue and detectable quantities in plasma even after 48 h. Good hemocompatibility with reduced in vivo platelet toxicity indicated that encapsulation in PLA-based nanocarrier helped ameliorate navitoclax associated thrombocytopenia. In vivo biological activity of NAV/DCB NPs evaluated in xenograft AML and syngeneic breast cancer model, demonstrated potent tumor growth inhibition efficacy. PLA-based NAV/DCB dual NPs present a novel, safe and effective nanoformulation for combination cancer therapy in both solid tumors and hematologic malignancies.

Antiagregación plaquetaria: stents, isquemia y sangrado ¿Qué sabemos al respecto? / Platelet antiaggregation: stents, ischemia and bleeding What do we know about it?

Antiplatelet therapy and percutaneous coronary intervention are two of the most important interventions in the management of coronary artery disease. In the last 20 years there has been groundbreaking advances in the pharmacotherapy and stent technology. Bleeding is the most feared complication of antiplatelet therapy, mainly due to the increase in major adverse cardiovascular events besides the bleeding itself. Different clinical decision tools have developed with the aim to define which patients have a high ischemic or bleeding risk, thus individualizing treatment.

Naringenin and morin reduces insulin resistance and endometrial hyperplasia in the rat model of polycystic ovarian syndrome through enhancement of inflammation and autophagic apoptosis.

Polycystic Ovary Syndrome (PCOS) is a gynecologic disorder with unsatisfactory treatment options. Hyperandrogenism and insulin resistance (IR) are two symptoms of PCOS. The majority of PCOS patients (approximately 50% to 70%) have IR and moderate diffuse inflammation of varying degrees. We investigated in-vitro and in-vivo effects of naringenin, morin and their combination on PCOS induced endometrial hyperplasia by interfering with the mTORC1 and mTORC2 signaling pathways. The vaginal smear test ensured the regular oestrous cycles in female rats. Serum cytokines (TNF-α and IL-6) were assessed using the ELISA test, followed by in-vivo and in-vitro determination of prominent gene expressions (mTORC1and C2, p62, LC3-II, and Caspase-3 involved in the inflammatory signaling mechanisms through RT-PCR, western bloting, or immunohistochemical analysis. In addition, the viability of naringenin or morin treated cells was determined using flow cytometry analysis. The abnormal oestrous cycle and vaginal keratosis indicated that PCOS was induced successfully. The recovery rate of the oestrous cycle with treatments was increased significantly (P<0.01) when compared to the PCOS model. Narigenin, morin, or a combination of the two drugs substantially decreased serum insulin, TNF-α, IL-6 levels with improved total anti-oxidant capacity and SOD levels (P<0.01). Treatments showed suppression of HEC-1-A cells proliferation with increased apoptosis (P<0.01) by the upregulation of Caspase-3 expression, followed by downregulation of mTORC, mTORC1, and p62 (P<0.01) expressions with improved LC3-II expressions (P<0.05) respectively. The histological findings showed a substantial increase in the thickness of granulose layers with improved corpora lutea and declined the number of cysts. Our findings noticed improved inflammatory and oxidative microenvironment of ovarian tissues in PCOS treated rats involving the autophagic and apoptotic mechanisms demonstrating synergistic in-vitro and in-vivo therapeutic effects of treatments on PCOS-induced endometrial hyperplasia.
