Squaric acid derivatives with cytotoxic activity- a review.

3,4-Dihydroxycyclobut-3-ene-1,2-dione (squaric acid, SQ) is the most important representative of the oxocarbon acids family. Squaric acid derivatives can be promising pharmaceutical agents, due to their unique structural properties, from which novel drugs benefit: a planar aromatic ring, the ability to form hydrogen bonds, good reactivity and similarity with carboxylate, phosphate and amide groups. These properties make it suitable for three major applications in cancer treatment. Firstly, due to their excellent ion binding ability, the halogenated squaramides can be used as artificial ion transporters or mobile carriers to disrupt Na+/Cl- gradients in cancer cells, thus hindering lysosomal function and inducing apoptosis. Another advantage of this class is their bioisosteric properties. Such molecules have been reported to be selective inhibitors of HDACs, FAK, SNM1A, MMP and kinases, involved in tumor growth and metastasis. Finally, the cyclobutenedione moiety proves to be a great linker in complex radiopharmaceuticals, used in theranostics. Its aromaticity and good reactivity make the generation and stability of these drugs easy and efficient. Multiple derivatives containing the squamide motif have been the subject of in-vitro investigations and have demonstrated anti-cancer activity in the nanomolar range against tumor cell lines, including colorectal adenocarcinoma, breast cancer, gastric carcinoma and cervical cancer. On the other hand, squaric acid derivative-Navarixin, has already been evaluated in Phase II clinical trials for its potential efficacy in the treatment of solid tumors. In this context this review is the first looking into the potential applications of squaric acid derivatives as anticancer therapies. It analyzes experimental studies presented in articles published between 2000 and 2024.

Unbiased Analysis of Knee Cartilage Thickness Change Over Three Years Post-Treatment with Sprifermin vs. Placebo – A Post-Hoc Analysis from the Phase II FORWARD Study

ObjectivePost-treatment cartilage morphometry in the FORWARD study was performed without blinding to MRI acquisition order, involving potential reader bias. Here we obtained unbiased estimates of cartilage change post-treatment, reading year (Y)2 and Y5 MRIs with blinding to time point. We studied whether post-treatment cartilage thickness change differed between sprifermin- and placebo-treated knees. MethodsFORWARD was a 5-year randomized control trial in 549 knee osteoarthritis patients. Here, Y2/Y5 images were analyzed with blinding to relative temporal order and treatment group. Cartilage change during Y2→Y5 was obtained in 337 participants: n=57 treated with placebo intra-articular injections every 6 months (q6M); n=69 with 30μg sprifermin every 12 months (q12M), n=67 with 30μg q6M, n=73 with 100μg q12M, and n=71 with 100μg q6M between baseline (BL) and 18M. Total femorotibial joint (TFTJ) cartilage thickness was the primary analytic focus. ResultsTFTJ cartilage thickness change during Y2→Y5 was -26μm (SD64; 95%CI -32,-19) across the cohort; no statistically significant difference (p=0.80) was observed between treatment or placebo arms (one-way ANOVA). All groups lost cartilage, but the treatment-related difference in cartilage thickness in Sprifermin arms relative to placebo at Y2 was maintained until Y5. Annualized cartilage change in placebo participants was -8.2μm (SD21; 95%CI -14,-2.5) during Y2→Y5 vs. -5.4μm (SD27; 95%CI -13,1.8) during BL→Y2; no significant difference was identified (t-test). ConclusionFORWARD is the first study evaluating post-treatment benefits of a potential disease modifying osteoarthritis drug. Cartilage thickness gained with 100μg sprifermin at Y2 is maintained to Y5 and thus appears viable and sustainable.This is a post-hoc analysis of the FORWARD trial: ClinicalTrials.gov Identifier: NCT01919164

Review on Oral Osmotic Tablet

Traditional oral medication delivery methods provide the drug with an immediate release and an efficient concentration at the intended location. Such a dosage regimen could lead to unexpected, ever-changing plasma concentrations. As a result, numerous regulated medication delivery systems are created. Among these, osmotic drug delivery systems (ODDS) and pulsatile drug delivery systems (PDDS) are becoming more and more significant because they improve patient treatment efficacy and compliance by delivering the medicine at precise times based on the course and physiological requirements of the disease. They regulate the drug’s delivery by using the osmotic pressure theory.To a significant extent, the drug’s release is unaffected by GIT physiological variables. Both targeted and systemic medication delivery are possible with these methods. The theoretical idea of drug delivery, various oral osmotic drug delivery system types, factors influencing the drug delivery system, benefits and drawbacks of these delivery systems, fundamental osmotic system components, evaluation parameters, difficulties, and emerging technologies in oral controlled drug delivery are all “highlighted” in this review.

Recent Advances in Peptide Drug Discovery: Novel Strategies and Targeted Protein Degradation.

Recent technological advancements, including computer-assisted drug discovery, gene-editing techniques, and high-throughput screening approaches, have greatly expanded the palette of methods for the discovery of peptides available to researchers. These emerging strategies, driven by recent advances in bioinformatics and multi-omics, have significantly improved the efficiency of peptide drug discovery when compared with traditional in vitro and in vivo methods, cutting costs and improving their reliability. An added benefit of peptide-based drugs is the ability to precisely target protein-protein interactions, which are normally a particularly challenging aspect of drug discovery. Another recent breakthrough in this field is targeted protein degradation through proteolysis-targeting chimeras. These revolutionary compounds represent a noteworthy advancement over traditional small-molecule inhibitors due to their unique mechanism of action, which allows for the degradation of specific proteins with unprecedented specificity. The inclusion of a peptide as a protein-of-interest-targeting moiety allows for improved versatility and the possibility of targeting otherwise undruggable proteins. In this review, we discuss various novel wet-lab and computational multi-omic methods for peptide drug discovery, provide an overview of therapeutic agents discovered through these cutting-edge techniques, and discuss the potential for the therapeutic delivery of peptide-based drugs.

Preferences for speed of access versus certainty of the survival benefit of new cancer drugs: a discrete choice experiment.

The extent to which patients with cancer are willing to accept uncertainty about the clinical benefit of new cancer drugs in exchange for faster access is not known. This study aims to examine preferences for access versus certainty, and to understand factors that influence these preferences. A US nationally representative sample of older adults were recruited via Cint, an online platform for survey research, to take part in an online discrete choice experiment. To be eligible, respondents had to self-report some experience with cancer-ie, they themselves, a close friend or a family member, previously or currently diagnosed with cancer. In the experiment, respondents chose between two cancer drugs, considering five attributes: functional status, life expectancy, certainty of the survival benefit of a new drug, effect of the drug on a surrogate endpoint, and delay in US Food and Drug Administration (FDA) approval time. The first primary outcome was the relative importance of certainty of survival benefit and wait time to respondents. The second primary outcome was willingness to wait for greater certainty of survival benefit, including subgroup analysis by cancer experience, age, education status, race or ethnicity and income. Secondary outcomes were changes in sensitivity to certainty and wait time, depending on the drug's effect on a surrogate endpoint, respondents' functional status, and life expectancy. The study plan was registered with ClinicalTrials.gov, NCT05936632. Between July 7 and July 20, 2023, 998 eligible respondents completed the survey. 870 respondents (461 [53%] male, 406 [47%] female, and three [<1%] other) were included in the final analysis. Respondents showed strong preferences for high certainty of survival benefit (coefficient 2·61, 95% CI 2·23 to 2·99), and strong preferences against a 1-year delay in FDA approval time (coefficient -1·04, 95% CI -1·31 to -0·77). Given very low certainty a drug would provide survival benefit (no evidence linking a surrogate endpoint to overall survival), respondents were willing to wait up to 21·68 months (95% CI 17·61 to 25·74) for high certainty (strong evidence) of survival benefit. A drug's effect on a surrogate endpoint had no significant impact on drug choices (coefficient 0·02, 95% CI -0·21 to 0·25). Older respondents (aged ≥55 years), non-White, lower-income (<$40 000 per year) individuals, and those with the lowest life expectancy, were most sensitive to wait time. Many cancer drugs approved through the FDA's accelerated approval pathway do not offer any survival benefit to patients. In this study, individuals expressed strong preferences for certainty that a cancer drug would offer survival benefit. Some individuals also expressed a higher willingness to wait for greater certainty than would be necessary to assess the survival benefit (over progression-free survival benefit) of most cancer drugs used in the metastatic setting.

What constitutes meaningful benefit of cancer drugs in the context of LMICs? A mixed-methods study of oncologists’ perceptions on endpoints, benefit, price, and value of cancer drugs

The importance of surrogate endpoints, magnitude of clinical benefit of cancer drugs, and their prices have often been debated in the oncology world. No study, however, has systemically explored oncologists' perception regarding these issues. We conducted a mixed-methods study including in-depth qualitative interviews of medical oncologists prescribing cancer drug therapy in India. Quantitative data were collected using a predetermined proforma. Qualitative in-depth interviews were audio-recorded, transcribed verbatim, anonymized, subsequently coded, and analyzed by generating basic and global themes. We interviewed 25 medical oncologists. Twenty-eight percent of oncologists rarely used cancer drugs that improved response rate (RR) but not overall survival (OS), and an equal percentage mostly/often used such drugs. For cancer drugs that improved progression-free survival (PFS) but not OS, 20% never/rarely used them while 48% mostly/often used them. Oncologists in India considered a 4.5-month (range, 1.5-12 months) advantage in median PFS as meaningful, and considered price of ∼120 United States Dollars (USD) per month (range, 48-720 USD per month) for those PFS gains as justified. For OS, median gains of 4.5 months (range, 2-24 months) and at a monthly price of ∼360 USD (range, 48-900 USD) was considered justified. Oncologists in India were aware and concerned that RR only meant tumour shrinkage not survival benefit, but many assumed that tumour shrinkage meant better quality of life. Many oncologists acknowledged the limitations of PFS but would use a drug with PFS benefit if it was cheaper than the drug with OS benefit. Oncologists in India showed awareness of the limited surrogacy between RR/PFS and OS but assumed that RR/PFS correlated with improved quality of life and acknowledged price as a factor in deciding treatment choices. This is the first study providing a benchmark for minimum clinical benefit (4.5 months in PFS or OS) and maximum monthly price (120 USD for PFS, 360 USD for OS) deemed justifiable by oncologists practicing in low-and-middle-income countries.

Prescription rebate guarantees: employerinsights.

To describe (1) rebate arrangements for specialty drugs, (2) the use and influence of benefits brokers and consultants, and (3) the importance of rebate-related factors when selecting a pharmacy benefits manager (PBM) among a sample of employers with self-funded pharmacybenefits. A national survey of employer drug benefit decision makers (N = 110) for organizations with self-insured pharmacy benefits. We summarized respondents' current rebate agreements for specialty drugs and their perspectives on the importance of rebates and rebate guarantees overall as well as by type of rebate agreement and by the person or entity identified as most influential in rebate strategy. Nearly two-thirds of employers reported having rebate agreements with a rebate guarantee for specialty drugs (n = 69; 62.7%). The person or entity most influential to rebate strategy decisions was often a benefits consultant (37.3%), a human resources/benefits leader (29.1%), or a benefits broker (21.8%). Employers with rebate guarantees ascribed a higher level of importance to guarantees when selecting a PBM (median [IQR], 9 [7-10]) than employers receiving rebates without a guarantee (7 [6-8]) and those who do not receive rebates (7.5 [4-9]) (P = .001). These findings shed light on the importance of rebate guarantees and the role of employer benefits consultants and brokers in PBM selection. Asthe public discourse on PBMs and drug rebates continues, it is important to recognize the role employer benefits consultants may play in perpetuating employer reliance on guaranteed rebate arrangements.

BRCA Mutation in Ovarian Cancer: Implications for Screening, Diagnosis, and Preventive Measures

Ovarian cancer is the most common gynaecological malignancy and the seventh most common malignancy in women. Inherited ovarian cancer is caused by mutations in certain genes, such as BRCA1 and BRCA2, as well as many minor genes. The pathology of ovarian cancer involves damage to the cell cycle mechanism secondary to mutations in BRCA1/2 protective genes. These mutations provide a meaningful marker for screening and diagnosing hereditary ovarian cancer. Classification of ovarian cancer is based on histology, depending on which layers of the ovary are affected. The authors conducted an electronic search using keywords and selected the included studies based on pre-established inclusion criteria. To avoid bias in the data extraction process, three reviewers extracted information independently. Risk assessment models provided by the National Comprehensive Cancer Network (NCCN) and American College of Obstetricians and Gynecologists (ACOG) are mostly used in clinical practice. The combination of serial serum cancer antigen-125 (CA-125) levels and transvaginal ultrasound is the only evidence-based screening approach available to patients at increased risk for ovarian cancer. Strong evidence has made salpingo-oophorectomy the gold standard for risk-reducing surgery. Bilateral salpingectomy, in contrast, is restricted to clinical trials currently. The protective effects of oral contraceptives have made them suitable agents for chemoprevention. Whilst the potential benefits of aspirin and certain other drugs have been investigated, further research is required to address the gap in data for them to be used in clinical practice for the purpose of ovarian cancer prevention.

Clinical Benefit, Price, and Regulatory Approval of Cancer Drugs Granted Breakthrough Therapy Designation in China, 2020-2024

The China National Drug Administration (NMPA) established the breakthrough therapy designation (BTD) in 2020 to encourage the accelerated development of drugs for the prevention and treatment of diseases that are life-threatening. However, the differences between BTD and non-BTD cancer drugs regarding clinical benefit, regulatory approval, and price are unclear. To compare BTD and non-BTD cancer drugs in clinical benefit (defined as efficacy and safety), novelty, time to approval, and average monthly treatment price. This cross-sectional study analyzes the original indication of BTD and non-BTD novel cancer drugs approved by the NMPA between July 8, 2020, and July 8, 2024. Data on efficacy, safety, regulatory approval, and price of cancer drugs were extracted from pivotal clinical trials based on review reports published by the NMPA, peer-reviewed articles or meeting reports, and winning bid prices for cancer drugs in the Chinese provincial-level centralized procurement process. The main outcome was the efficacy and safety associated with BTD vs non-BTD cancer drugs, including progression-free survival (PFS), response rate (RR), duration of response, serious adverse events, grade 3 or higher adverse events, and treatment-related deaths. In addition, the time to approval, novelty, and initial and latest average monthly treatment prices were evaluated, as well as the average annual reduction rate (AARR; the sum of the reduction rates divided by the number of years for the monthly treatment price) for these cancer drugs. Between July 2020 and July 2024, 18 BTD (36%) and 32 non-BTD (64%) cancer drugs were approved by the NMPA. The median (IQR) clinical development time for BTD drugs was significantly shorter than for non-BTD drugs (5.6 [95% CI, 4.3-7.3] vs 6.6 [95% CI, 6.0-8.5] years; P = .02). No significant differences were observed in PFS (HR, 0.44 [95% CI, 0.38-0.52] vs HR, 0.51 [95% CI, 0.40-0.65]; P = .20), PFS gained (median [IQR], 5.4 [3.9-7.0] vs 2.7 [2.6-5.9] months; P = .77), RR (58% [95% CI, 45%-74%] vs 59% [95% CI, 51%-69%]; P = .85), and duration of response (median [IQR], 18.0 [15.0-21.6] vs 11.1 [7.4-17.4] months; P = .09) between BTD and non-BTD drugs. The rates of serious adverse events (37% [95% CI, 26%-52%] vs 32% [95% CI, 27%-36%]; P = .45), adverse events grade 3 or higher (64% [95% CI, 53%-77%] vs 55% [95% CI, 45%-68%]; P = .31), and treatment-related deaths (2% [95% CI, 1%-4%] vs 1% [95% CI, 1%-2%]; P = .10) were similar between BTD and non-BTD drugs. BTD drugs are more likely to be first-in-class drugs (5 of 18 [28%] vs 1 of 32 [3%]; P = .02). Differences in the median (IQR) initial ($5665 [$3542-$9321] vs $3361 [$2604-$5474]; P = .06) and latest ($5665 [$1553-$9321] vs $2145 [$1318-$4276]; P = .18) average monthly treatment prices for BTD drugs and non-BTD drugs were not significant. The median (IQR) AARRs for BTD drugs and non-BTD drugs were 15.2% (0%-46.9%) and 19.8% (1.0%-42.9%), respectively. The findings of this cross-sectional study suggest that BTD has facilitated faster time to market for cancer drugs and improved novelty, but the price of treatment is relatively higher. There was no significant difference on comparative efficacy and safety.

Cosmeceuticals are the product of cosmetics that are biologically active ingredient that impersonates to medical or drug benefits. But the daily use of synthetic results in many side effects and need of organic lip balms is roaring in the society. In the present study we, aimed to formulate organic lip balm using natural ingredients. Lip balm has been formulated using Golden shower flower, red cabbage, honey, ghee, beeswax, vitamin E and coconut oil. Various parameters such as stability, melting point, spreadability, pH, were evaluated for the evaluation of lip balm. pH was found to be 6 and melting point was 60°C 65°C for cassia lip balm and red cabbage lip balm respectively. On preforming skin irritation test the formulation was found to be not irritant, and formulation was observed to be stable. Lip balm from above ingredients could be a better option for daily use to a small extend for minor lip issues.

Early pirfenidone treatment enhances lung function in idiopathic pulmonary fibrosis patients.

This editorial comments on the study by Lei et al investigating the efficacy of early treatment with pirfenidone on the lung function of patients with idiopathic pulmonary fibrosis (IPF) published. This study evaluates the efficacy of early treatment with pirfenidone on lung function in patients with IPF. The early and advanced stages of IPF are defined, highlighting the drug's benefits. While prior research indicates pirfenidone's effectiveness in advanced IPF, this study focuses on its advantages in early stages. The study emphasizes the importance of computed tomography imaging alongside biochemical data and lung function tests for a comprehensive analysis of symptom relief. Results show that early intervention with pirfenidone significantly reduces disease progression and preserves lung function, underscoring its potential as a critical treatment strategy in early IPF.

The effects of sodium-glucose cotransporter 2 inhibitors on the 'forgotten' right ventricle.

With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF). In addition, right HF (RHF) is a common complication associated with various diseases, including congenital heart disease, myocardial infarction (MI), pulmonary arterial hypertension (PAH) and dilated cardiomyopathy (DCM), and it can manifest at any time after left ventricular assist devices (LVADs). The sodium-glucose cotransporter 2 (SGLT2) inhibition by gliflozins has emerged as a cornerstone medicine for managing type 2 diabetes mellitus (T2DM) and HF, with an increasing focus on its potential to enhance RV function. In this review, we aim to present an updated perspective on the pleiotropic effects of gliflozins on the right ventricle and offer insights into the underlying mechanisms. We can ascertain their advantageous impact on the right ventricle by discussing the evidence obtained in animal models and monumental clinical trials. In light of the pathophysiological changes in RHF, we attempt to elucidate crucial mechanisms regarding their beneficial effects, including alleviation of RV overload, reduction of hyperinsulinaemia and inflammatory responses, regulation of nutrient signalling pathways and cellular energy metabolism, inhibition of oxidative stress and myocardial fibrosis, and maintenance of ion balance. Finally, this drug class's potential application and benefits in various clinical settings are described, along with a prospective outlook on future clinical practice and research directions.

Digoxin Discontinuation in Patients with HFrEF on Beta-Blockers: Implication for Future “Knock-Out Trials” in Heart Failure

Background: National heart failure guidelines recommend quadruple therapy with renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter 2 inhibitors for patients with heart failure with reduced ejection fraction (HFrEF), most of whom also receive loop diuretics. However, the guidelines are less clear about the safe approaches to discontinuing older drugs whose decreasing or residual benefit is less well understood. The objective of this study was to examine whether digoxin can be safely discontinued in patients with HFrEF receiving beta-blockers. Methods: In OPTIMIZE-HF, of 2,477 patients with HFrEF (EF ≤45%) receiving beta-blockers and digoxin, digoxin was discontinued in 450 patients. We assembled a propensity score-matched cohort of 433 pairs of patients in which digoxin continuation vs. discontinuation groups were balanced on 51 baseline characteristics. Using the same approach, from 992 patients not on beta-blockers, we assembled a matched cohort of 198 pairs of patients also balanced on 51 baseline characteristics. Hazard ratios (HRs) and 95% CIs for one-year outcomes were estimated. Results: Among patients receiving beta-blockers, digoxin discontinuation had no association with the combined endpoint of heart failure readmission or death (HR, 1.01; 95% CI, 0.85–1.19), heart failure readmission (HR, 1.03; 95% CI, 0.85–1.25) or death (HR, 0.91; 95% CI, 0.72–1.14). Respective HRs (95% CIs) among patients not receiving beta-blockers were 1.60 (1.25–2.04), 1.62 (1.18–2.22) and 1.43 (1.08–1.89). Conclusions: Digoxin can be discontinued without increasing the risk of adverse outcomes in patients with HFrEF receiving beta-blockers. Future studies need to examine the residual benefit of older heart failure drugs to ensure their safe discontinuation in patients with HFrEF receiving newer guideline-directed medical therapy.

Protocolo terapéutico de la diabetes mellitus tipo 2 con obesidad y riesgo cardiovascular

The management of type 2 diabetes mellitus (DM2) with obesity and cardiovascular risk is a growing challenge due to the high prevalence of both conditions. This protocol describes therapeutic recommendations based on glycemic control and the cardiovascular benefits of certain drugs. Two classes of drugs with weight and cardiometabolic efficacy stand out: glucagon-like peptide-1 agonists (GLP-1a) and sodium-glucose cotransporter-2 inhibitors (SGLT-2i). This document suggests the joint use of both to reduce cardiovascular risk and promote weight loss. It also describes the role of metabolic surgery as an effective option for the management of DM2 and obesity, as it significantly improves glycemic outcomes and reduces cardiovascular risk. Continuous follow-up is recommended to adjust treatment according to the patient's clinical response and to avoid therapeutic inertia.

Disparities in the utilization of supportive care medications among older adults with metastatic pancreatic ductal adenocarcinoma.

51 Background: Inequities in cancer care delivery can profoundly affect access to high-quality treatments and patient outcomes. Supportive care medication use is important for preserving quality of life in older adults with metastatic pancreatic ductal adenocarcinoma (PDAC). Whether there are differences in supportive care medication use by race and sex is unknown. Our objectives were to assess the racial/ethnic and biological sex inequities in use of treatments for pain, depression, and pancreatic insufficiency-related treatments (PERT) among older adults with PDAC. Methods: We used the Surveillance, Epidemiology, and End Results-Medicare linked database, to identify Medicare beneficiaries aged 65 and older diagnosed with metastatic PDAC from January 2008 to December 2019. We included those continuously enrolled in Medicare prescription drug benefits in the 6 months before and month of diagnosis. Any use of opioid pain medications, antidepressants, and PERT was identified from diagnosis to the end of the study period (at death, disenrollment, or 12 months). Multivariable regression was used to compare supportive care medications use by racial/ethnic and biological sex groups. Results: There were 29,509 individuals in our sample, with12.9% Black patients, 3.9% Hispanic patients, and 83.2% White patients. The mean age was 76.5 (SD: 7.4) years. Mean follow-up time was 135.4 (SD:117.7) days overall, with the shortest follow-up among Black patients 124 (SD:111.1) days and longest for White patients 137.5 (SD: 118.8) days. Antidepressants were used by 23.8%, opioids by 60.3%, and PERT by 12.4% overall. Within race groups there were limited differences in medication use by sex. However, we observed differences in supportive care treatment use by race and ethnicity. Specifically, relative to White individuals, those who identified as Black were 20% less likely (adjusted risk ratio [aRR]: 0.8, 95% CI:0.74-0.85) to receive antidepressants, 14% less likely to receive opioids (aRR: 0.86, 95% CI:0.84-0.89), and 41% less likely to receive PERT (aRR: 0.59, 95% CI:0.53-0.65). Similar patterns were observed for patients of Hispanic ethnicity, with those individuals being 12% less likely (adjusted risk ratio[aRR]: 0.88, 95% CI:0.89-0.98) to receive antidepressants, 9% less likely to receive opioids (aRR: 0.91, 95% CI:0.87-0.96), and 42% less likely to receive PERT (aRR: 0.58, 95% CI:0.47-0.70). Conclusions: Our preliminary data showed differences in the uptake of supportive care drugs among Black and Hispanic patients relative to White patients. Specifically, these individuals were less likely to start opioid pain medications, antidepressants, and pancreatic enzyme replacement therapy compared to their White counterparts. These findings highlight potential gaps in treatment use that may better support patients facing life-limiting illnesses.

Experimental Study of the Promotional Implications of Proprietary Prescription Drug Names.

The meaning and characteristics embedded in proprietary drug names have the potential to affect name recall, perceptions of drug benefits and risks, and attitudes toward a drug. In this study, we examined: (1) whether names that reference the drug's medical indication affect consumers' and primary care physicians' (PCPs') perceptions of the drug and (2) whether names that overstate the drug's efficacy affect consumers' and PCPs' perceptions of the drug. We conducted an online experiment with 455 PCPs and 450 consumers to test the effects of fictitious proprietary prescription drug names. Participants were randomized to view one neutral drug name, one name that overstated the drug's efficacy, and five names that referenced the drug's medical indication. Names that referenced the drug's medical indication and names that overstated the drug's benefit both influenced perceptions of efficacy and risk compared to neutral names. For several outcomes, names evoking medical indications had similar effects to those designed to overstate the drug's efficacy. The patterns of effects were similar for PCPs and consumers. Findings suggest drug names alone can be sufficient to produce attitudes and risk and benefit perceptions about drugs, even in the absence of any information beyond the drug's medical indication.

Cyclic adenosine monophosphate critically modulates cardiac GLP-1 receptor's anti-inflammatory effects.

Glucagon-like peptide (GLP)-1 receptor (GLP1R) agonists exert a multitude of beneficial cardiovascular effects beyond control of blood glucose levels and obesity reduction. They also have anti-inflammatory actions through both central and peripheral mechanisms. GLP1R is a G protein-coupled receptor (GPCR), coupling to adenylyl cyclase (AC)-stimulatory Gs proteins to raise cyclic 3`-5`-adenosine monophosphate (cAMP) levels in cells. cAMP exerts various anti-apoptotic and anti-inflammatory effects via its effectors protein kinase A (PKA) and Exchange protein directly activated by cAMP (Epac). However, the precise role and importance of cAMP in mediating GLP1R`s anti-inflammatory actions, at least in the heart, remains to be determined. To this end, we tested the effects of the GLP1R agonist liraglutide on lipopolysaccharide (LPS)-induced acute inflammatory injury in H9c2 cardiac cells, either in the absence of cAMP production (AC inhibition) or upon enhancement of cAMP levels via phosphodiesterase (PDE)-4 inhibition with roflumilast. Liraglutide dose-dependently inhibited LPS-induced apoptosis and increased cAMP levels in H9c2 cells, with roflumilast but also PDE8 inhibition further enhancing cAMP production by liraglutide. GLP1R-stimulated cAMP markedly suppressed the LPS-dependent induction of pro-inflammatory tumor necrosis factor (TNF)-a, interleukin (IL)-1b, and IL-6 cytokine expression, of inducible nitric oxide synthase (iNOS) expression and nuclear factor (NF)-kB activity, of matrix metalloproteinases (MMP)-2 and MMP-9 levels and activities, and of myocardial injury markers in H9c2 cardiac cells. The effects of liraglutide were mediated by the GLP1R since they were abolished by the GLP1R antagonist exendin(9-39). Importantly, AC inhibition completely abrogated liraglutide`s suppression of LPS-dependent inflammatory injury, whereas roflumilast significantly enhanced the protective effects of liraglutide against LPS-induced inflammation. Finally, PKA inhibition or Epac1/2 inhibition alone only partially blocked liraglutide`s suppression of LPS-induced inflammation in H9c2 cardiac cells, but, together, PKA and Epac1/2 inhibition fully prevented liraglutide from reducing LPS-dependent inflammation. cAMP, via activation of both PKA and Epac, is essential for GLP1R`s anti-inflammatory signaling in cardiac cells and that cAMP levels crucially regulate the anti-inflammatory efficacy of GLP1R agonists in the heart. Strategies that elevate cardiac cAMP levels, such as PDE4 inhibition, may potentiate the cardiovascular, including anti-inflammatory, benefits of GLP1R agonist drugs.

Summary of the 2023 European Society of Cardiology clinical guidelines on the management of cardiovascular disease in patients with diabetes mellitus

The prevalence of cardiovascular diseases (CVDs) is well known. According to the World Health Organization (WHO), almost 18 million people die from CVDs worldwide every year, accounting for 31% of all causes of death [1]. CVDs often develop concomitantly with diabetes mellitus (DM), with approximately 20% of cardiovascular deaths attributed to elevated blood glucose levels [2]. Notably, CVDs are the leading cause of death among patients with type 2 diabetes (T2DM). Based on data from the Federal Register of Diabetes 2022 in Russia, chronic heart failure was the direct cause of death in 24.2% of T2DM cases, followed by acute heart failure (13.1%), cerebrovascular events (10.0%), and myocardial infarction (3.7%) [3].The pathophysiological interplay between atherosclerotic cardiovascular disease and DM has led to a situation where cardiologists are increasingly involved in the treatment of patients with DM, while endocrinologists are encountering a growing number of patients with CVDs. This association has become so apparent that in a recent article published in the European Journal of Cardiology, Yu. Braunwald speculated about the emergence of a new subspecialty - diabetocardiology [4]. Unfortunately, experts predict that the global number of diabetic patients will reach 783 million [5].Recent data on the CV benefits of certain hypoglycemic drugs (primarily, certain SGLT2 inhibitors, several GLP-1 receptor agonists, and a novel non-steroidal mineralocorticoid receptor antagonist finerenone) prove the need for a unified interdisciplinary approach to managing CVDs and DM.Given the importance of integrated and coordinated efforts in managing patients with CVD and DM, the Task Force of the -European Society of Cardiology (ESC) updated, formulated, and published clinical guidelines on the treatment of CVD in diabetic patients in 2023 [6]. This article provides a concise overview of the key provisions outlined in the guidelines.

Evidence from an Applied Research Health Question (AHRQ): Physician-prescribed medications to children for oral health issues

ObjectivesTo understand changes in prescription patterns over time, and support dental and oral health program planning, Toronto Public Health issued an AHRQ request to collect information on physician-prescribed medications following an oral health-related incident. ApproachAn algorithm was created to identify oral health-related incidents among children and youth aged up to 17 years old in Ontario and Toronto during fiscal years 2013 to 2022. The algorithm used provincial data on physician visits, emergency department visits, inpatient hospitalizations, or day surgeries to define ‘dental-related incidents’. Physician-prescribed medications (e.g., chlorhexidine, opioids, benzodiazepines, antibiotics, NSAIDs and others) within seven days of a dental-related incident were recorded using Ontario Drug Benefit Claims and the Narcotics Monitoring System. ResultsOf 522,674 dental-related incidents in Ontario between 1 April 2013 and 31 March 2023, 9.2% had physician-prescribed medications (versus 8.6% of 90,810 dental-related incidents in Toronto). The proportion of incidents with prescriptions increased from 6.4% in 2013 to 10.7% in 2022 in Ontario, and from 5.9% to 10.3% in Toronto. The most prescribed medication was antibiotics, followed by immediate-release combination medications and non-long-acting medications. Conclusions/ImplicationsOver the 10-year period examined, an increasing proportion of dental-related incidents had physician-prescribed medications, which may be attributed to the implementation of Ontario’s pharmacare program (OHIP+) in 2018. Early access to routine and preventative dental care could become more accessible as part of Canada’s new federal dental program. Results from this AHRQ will inform better resource allocation in dental and oral health program planning, potentially reducing avoidable healthcare costs.

Treatment Effects in Randomized and Nonrandomized Studies of Pharmacological Interventions

Randomized clinical trials (RCTs) are widely regarded as the methodological benchmark for assessing clinical efficacy and safety of health interventions. There is growing interest in using nonrandomized studies to assess efficacy and safety of new drugs. To determine how treatment effects for the same drug compare when evaluated in nonrandomized vs randomized studies. Meta-analyses published between 2009 and 2018 were identified in MEDLINE via PubMed and the Cochrane Database of Systematic Reviews. Data analysis was conducted from October 2019 to July 2024. Meta-analyses of pharmacological interventions were eligible for inclusion if both randomized and nonrandomized studies contributed to a single meta-analytic estimate. For this meta-analysis using a meta-epidemiological framework, separate summary effect size estimates were calculated for nonrandomized and randomized studies within each meta-analysis using a random-effects model and then these estimates were compared. The reporting of this study followed the Guidelines for Reporting Meta-Epidemiological Methodology Research and relevant portions of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline. The primary outcome was discrepancies in treatment effects obtained from nonrandomized and randomized studies, as measured by the proportion of meta-analyses where the 2 study types disagreed about the direction or magnitude of effect, disagreed beyond chance about the effect size estimate, and the summary ratio of odds ratios (ROR) obtained from nonrandomized vs randomized studies combined across all meta-analyses. A total of 346 meta-analyses with 2746 studies were included. Statistical conclusions about drug benefits and harms were different for 130 of 346 meta-analyses (37.6%) when focusing solely on either nonrandomized or randomized studies. Disagreements were beyond chance for 54 meta-analyses (15.6%). Across all meta-analyses, there was no strong evidence of consistent differences in treatment effects obtained from nonrandomized vs randomized studies (summary ROR, 0.95; 95% credible interval [CrI], 0.89-1.02). Compared with experimental nonrandomized studies, randomized studies produced on average a 19% smaller treatment effect (ROR, 0.81; 95% CrI, 0.68-0.97). There was increased heterogeneity in effect size estimates obtained from nonrandomized compared with randomized studies. In this meta-analysis of treatment effects of pharmacological interventions obtained from randomized and nonrandomized studies, there was no overall difference in effect size estimates between study types on average, but nonrandomized studies both overestimated and underestimated treatment effects observed in randomized studies and introduced additional uncertainty. These findings suggest that relying on nonrandomized studies as substitutes for RCTs may introduce additional uncertainty about the therapeutic effects of new drugs.
