ABSTRACT

BACKGROUND: The adverse effects of pulmonary arterial hypertension (PAH) on physical, emotional, and health-related quality of life (HRQoL) remain primarily unrecognized, especially in resource-limited settings. OBJECTIVES: This study aims to characterize the HRQoL of patients with PAH in this area and also identify the potential role of clinically relevant characteristics, including the 6-min walk distance test (6MWD), WHO-Functional Classification (WHO-FC), and mental health in the occurrence of lowering quality of life. DESIGN: This was a cross-sectional observational study. METHODS: Inpatients with PAH were chosen from a tertiary hospital located in Gansu province, China. All participants were interviewed face-by-face by using questionnaires, including items from the 36-Item Short Form Health Survey (SF-36), the self-rating anxiety scale, and the self-rating depression scale. Data on demographic and clinically relevant characteristics, including WHO-FC and 6MWD, were also collected by tracing medical recorders. Multiple linear regression analysis was used to determine the association between demographic, clinically relevant characteristics data, and physical component summary (PCS) or mental component summary (MCS) in SF-36. RESULTS: Of the 152 participants, SF-36 differed significantly from Chinese norms in all eight domains, with role-physical (21.55 ± 9.87) less than one-third of the norm (88.79 ± 28.49). Multiple linear regression results showed that the factors with the greatest impact on PCS were anxiety scores (ß = -0.22, p = 0.001), followed by WHO-FC (ß = -0.16, p = 0.014) and 6MWD (ß = 0.15, p = 0.036). The factors with the greatest impact on MCS were WHO-FC (ß = -0.30, p < 0.001), followed by anxiety (ß = -0.23, p = 0.001) and depression scores (ß = -0.16, p = 0.013). CONCLUSION: HRQoL was substantially reduced among PAH patients in the resource-limited area, mainly the physiological functions. WHO-FC and anxiety scores were independently associated with both PCS and MCS in SF-36. Clinicians should make reasonable rehabilitation programs and plans for patients according to their cardiac function grade and the severity of clinical symptoms. In addition, psychological interventions should also be taken, especially for those with anxiety symptoms, so as to improve their HRQoL.

ABSTRACT

The testosterone undecanoate oil solution is the most widely used injection of testosterone for long-acting effects on the market, whereas the formulation carries the potential risk of causing pulmonary vascular embolism, inflammation, and pain at the injection site. Therefore, a sustained-released long-acting injection of testosterone with strong security is urgently exploited. Herein, a poorly water-soluble testosterone-cholesterol prodrug (TST-Chol) was synthesized by esterification. The water solubility of TST-Chol was decreased by 644 folds in comparison to that of testosterone (TST). Moreover, suspensions of TST and TST-Chol were prepared and analyzed in vitro, utilizing three distinct particle sizes: small-sized nanocrystals (SNCs) measuring 300 nm, medium-sized microcrystals (MMCs) measuring 12 µm, and large-sized microcrystals (LMCs) measuring 20 µm. The findings from the in vitro release study indicated that the sustained release of the drug was significantly influenced by the solubility and particle sizes of the suspension. Notably, the suspensions with low water solubility and larger particle sizes exhibited a more desirable sustained-release effect in vitro. Furthermore, the study on pharmacokinetics exhibited that TST-Chol SNCs produced a sustained TST plasma concentration in vivo for up to 40 days and no obvious pathological changes in lung tissue were found. Our study indicated that solubility and particle sizes of suspensions had made a difference in pharmacokinetics and provided a valuable reference for the advancement of long-acting injections.

ABSTRACT

Latuda® is an oral tablet approved by the US Food and Drug Administration (FDA) for the treatment of schizophrenia. However, the clinical efficacy of Latuda® is compromised by patient noncompliance due to frequent daily administration, especially for patients experiencing severe schizophrenia, whose medication is often needed for several months to years. Hence, developing a long-acting injectable formulation of lurasidone is urgently needed. Herein, a poorly water-soluble lurasidone pamoate (LP) salt was synthesized via the facile ion pair-based salt formation technology. The solubility of LP was decreased by 233 folds compared with that of lurasidone hydrochloride (LH). Furthermore, suspensions of LH and LP with three different particle sizes, including 400 nm small-sized nanocrystals (SNCs), 4 µm medium-sized microcrystals (MMCs), and 15 µm large-sized microcrystals (LMCs) were prepared and characterized by powder X-ray diffraction (PXRD) and differential scanning calorimetry (DSC). The in vitro release results showed that particle sizes had great effects on the sustained release of LH, where large-sized particles exhibited superior sustained release than the smaller ones. Besides, LP suspensions exhibited better sustained release than LH suspensions at the same size scale. Moreover, the pharmacokinetics showed that LP LMCs produced an extended in vivo intramuscularly injectable profile for up to 45 days, which was 10 days longer than that of the LH LMCs. Our findings demonstrated that particle size had appreciable impacts on drug sustained release and provided valuable knowledge for the rational design of optimized micronized suspensions for long-acting injectables.

ABSTRACT

Inspired by the natural phenomenon of phenolic-protein interactions, we translate this "naturally evolved interaction" to a "phenolic acid derivative based albumin bound" technology, through the synthesis of phenolic acid derivatives comprising a therapeutic cargo linked to a phenolic motif. Phenolic acid derivatives can bind to albumin and form nanocomplexes after microfluidic mixing. This strategy has been successfully applied to different types of anticancer drugs, including taxanes, anthraquinones, etoposides, and terpenoids. Paclitaxel was selected as a model drug for an in-depth study. Three novel paclitaxel-phenolic acid conjugates have been synthesized. Molecular dynamics simulations provide insights into the self-assembled mechanisms of phenolic-protein nanocomplexes. The nanocomplexes show improved pharmacokinetics, elevated tolerability, decreased neurotoxicity, and enhanced anticancer efficacies in multiple murine xenograft models of breast cancer, in comparison with two clinically approved formulations, Taxol (polyoxyethylated castor oil-formulated paclitaxel) and Abraxane (nab-paclitaxel). Such a robust system provides a broadly applicable platform for the development of albumin-based nanomedicines and has great potential for clinical translation.

ABSTRACT

BACKGROUND: Further clarification is needed regarding the association between adverse childhood experiences (ACEs) and the risk of diabetes. To conduct a systematic review with meta-analysis of studies assessing the association between ACEs and the risk of diabetes. METHOD: We conducted a systematic literature search of PubMed, Embase, and Cochrane Library for published studies describing the association between ACEs and diabetes in December 2021. We examined the overall relationship between ACEs and diabetes and performed a subgroup analysis based on the type of ACEs, number of ACEs, and gender. RESULTS: A total of 17 studies were included. The results of Meta-analysis showed the significant estimated effect of ACEs on diabetes (OR = 1.20, 95%CI: 1.07, 1.35). The subgroup analysis found a significant association between neglect (OR = 1.61, 95%CI: 1.11, 2.33), family dysfunction (OR = 1.14, 95%CI: 1.05, 1.24) and diabetes, respectively. Gender and the number of ACEs were factors that significantly affect the risk of diabetes. CONCLUSION: The results suggest that ACEs were significantly associated with an elevated risk of diabetes, especially for exposure to neglect, family dysfunction, and two or more ACES. Effective ACEs screening for children and intervention among high-risk populations should be taken so as to reduce the incidence of diabetes.

ABSTRACT

OBJECTIVE: To evaluate the reporting quality of randomized controlled trial (RCT) abstracts regarding patients with coronavirus disease 2019 (COVID-19) and to analyze the factors influencing the quality. METHODS: The PubMed, Embase, Web of Science, and Cochrane Library databases were searched to collect RCTs on patients with COVID-19. The retrieval time was from inception to December 1, 2020. The CONSORT statement for abstracts was used to evaluate the reporting quality of RCT abstracts. RESULTS: A total of 53 RCT abstracts were included. The CONSORT statement for abstracts showed that the average reporting rate of all items was 50.2%. The items with a lower reporting quality were mainly the trial design and the details of randomization and blinding (<10%). The mean overall adherence score across all studies was 8.68 ± 2.69 (range 4-13.5). Multivariate linear regression analysis showed that the higher reporting scores were associated with higher journal impact factor (P < 0.01), international collaboration (P = 0.04), and structured abstract format (P < 0.01). CONCLUSIONS: Although many RCTs on patients with COVID-19 have been published in different journals, the overall quality of reporting in the included RCT abstracts was suboptimal, thus diminishing their potential usefulness, and this may mislead clinical decision-making. In order to improve the reporting quality, it is necessary to promote and actively apply the CONSORT statement for abstracts.

ABSTRACT

OBJECTIVE: To evaluate the reporting quality of randomized controlled trials (RCTs) regarding patients with COVID-19 and analyse the influence factors. METHODS: PubMed, Embase, Web of Science and the Cochrane Library databases were searched to collect RCTs regarding patients with COVID-19. The retrieval time was from the inception to December 1, 2020. The CONSORT 2010 statement was used to evaluate the overall reporting quality of these RCTs. RESULTS: 53 RCTs were included. The study showed that the average reporting rate for 37 items in CONSORT checklist was 53.85% with mean overall adherence score of 13.02±3.546 (ranged: 7 to 22). The multivariate linear regression analysis showed the overall adherence score to the CONSORT guideline was associated with journal impact factor (P = 0.006), and endorsement of CONSORT statement (P = 0.014). CONCLUSION: Although many RCTs of COVID-19 have been published in different journals, the overall reporting quality of these articles was suboptimal, it can not provide valid evidence for clinical decision-making and systematic reviews. Therefore, more journals should endorse the CONSORT statement, authors should strictly follow the relevant provisions of the CONSORT guideline when reporting articles. Future RCTs should particularly focus on improvement of detailed reporting in allocation concealment, blinding and estimation of sample size.
