The LISA-PPV Formula: An Ensemble Artificial Intelligence-Based Thick Intraocular Lens Calculation Formula for Vitrectomized Eyes.

PURPOSE: To investigate the relationship between effective lens position (ELP) and patient characteristics, and to further develop a new intraocular lens (IOL) calculation formula for cataract patients with previous pars plana vitrectomy (PPV). DESIGN: Cross-sectional study. METHODS: A total of 2793 age-related cataract patients (group 1) and 915 post-PPV cataract patients (group 2) who underwent phacoemulsification with IOL implantation were included. The ELP of 2 groups was compared and the association between ELP and patient characteristics was further evaluated using standardized multivariate regression coefficients. An ensemble artificial intelligence-based ELP prediction model was developed using a training set of 810 vitrectomized eyes, and a thick-lens IOL formula (LISA-PPV) was constructed and compared with 7 existing formulas on an external multi-center testing set of 105 eyes. RESULTS: Compared to eyes with age-related cataract, vitrectomized eyes showed a similar ELP distribution (P = .19), but different standardized coefficients of preoperative biometry for ELP. The standardized coefficients also varied with the type of vitreous tamponade, history of scleral buckling, and ciliary sulcus IOL implantation. The LISA-PPV formula showed the lowest mean and median absolute prediction error (MAE: 0.63 D; MedAE: 0.44 D), and the highest percentages of eyes within ±0.5 D of prediction error (57.14%) in the testing dataset. CONCLUSIONS: The ELP prediction required optimization specifically for vitrectomized eyes based on their biometric and surgical characteristics. The LISA-PPV formula is a useful and accurate tool for determining IOL power in cataract patients with previous PPV (available at http://ppv-iolcalculator.com/).

Correlates of sexual and reproductive health service utilization among older adults in China: Findings from the sexual well-being (SWELL) study.

BACKGROUND: Sexual and reproductive health (SRH) is critical to the overall health of older adults. We assessed the utilization of SRH services and its correlates among older adults in China. METHODS: We recruited community-dwelling adults aged 50 and above in five Chinese cities between June 2020 and December 2022. In this study SRH services included reproductive health examination, cervical cancer screening, and sexual life counselling. Logistic regression was used to assess correlates of SRH services utilization. RESULTS: A total of 3001 older adults (1819 men and 1182 women) were enrolled. Among them, 11.4 % (343/3001) of participants received a reproductive health examination, 35.4 % (418/1182) of female participants received cervical cancer screening, and 30.1 % (401/1332) of sexually active participants sought help for their sexual lives. Older men with an annual income of USD 7500 or more (aOR = 3.21, 95%CI: 1.39-7.44), two or more chronic conditions (2.38, 1.39-4.08), and reproductive health problems (2.01, 1.18-3.43) were more likely to receive a urological examination. For older women, individuals who were younger (aged 50-59 years: 5.18, 2.84-9.43; aged 60-69 years: 2.67, 1.49-4.79), lived in an urban area (1.88, 1.31-2.71), were employed (1.73, 1.21-2.47), had two or more chronic conditions (2.04, 1.37-3.05), were sexually active (1.72, 1.15-2.58) and talked about sex (1.69, 1.21-2.36) were more likely to receive a gynecological examination. CONCLUSION: SRH services utilization among older adults was low, with urological examination among older men particularly low. SRH messages and services tailored for older adults are needed to enhance their utilization of SRH services.

Landscape of adenosine pathway and immune checkpoint dual blockade in NSCLC: progress in basic research and clinical application.

Lung cancer poses a global threat to human health, while common cancer treatments (chemotherapy and targeted therapies) have limited efficacy. Immunotherapy offers hope of sustained remission for many patients with lung cancer, but a significant proportion of patients fail to respond to treatment owing to immune resistance. There is extensive evidence to suggest the immunosuppressive microenvironment as the cause of this treatment failure. Numerous studies have suggested that the adenosine (ADO) pathway plays an important role in the formation of an immunosuppressive microenvironment and may be a key factor in the development of immune resistance in EGFR-mutant cell lung cancer. Inhibition of this pathway may therefore be a potential target to achieve effective reversal of ADO pathway-mediated immune resistance. Recently, an increasing number of clinical trials have begun to address the broad prospects of using the ADO pathway as an immunotherapeutic strategy. However, few researchers have summarized the theoretical basis and clinical rationale of the ADO pathway and immune checkpoint dual blockade in a systematic and detailed manner, particularly in lung cancer. As such, a timely review of the potential value of the ADO pathway in combination with immunotherapy strategies for lung cancer is warranted. This comprehensive review first describes the role of ADO in the formation of a lung tumor-induced immunosuppressive microenvironment, discusses the key mechanisms of ADO inhibitors in reversing lung immunosuppression, and highlights recent evidence from preclinical and clinical studies of ADO inhibitors combined with immune checkpoint blockers to improve the lung cancer immunosuppressive microenvironment.

Metal-Organic Framework Based Sensors for Benzene Vapor.

Sensing of benzene vapor is a hot spot due to the volatile drastic carcinogen even at trace concentration. However, achieving convenient and rapid detection is still a challenge. As a sort of functional porous material, metal-organic frameworks (MOFs) have been developed as detection sensors by adsorbing benzene vapor and converting it into other signals (fluorescence intensity/wavelength, chemiresistive, weight or color, etc.). Supramolecular interaction between benzene molecules and the host framework, aperture size/shape and structural flexibility are influential factors in the performance of MOF-based sensors. Therefore, enhancing the host-guest interactions between the host framework and benzene molecules, or regulating the diffusion rate of benzene molecules by changing the aperture size/shape and flexibility of the host framework to enhance the detection signal are effective strategies for constructing MOF-based sensors. This concept highlights several types of MOF-based sensors for the detection of benzene vapor.

Engineering a Z-Scheme Heterostructure on ZnIn2S4@NH2-MIL-125 Composites for Boosting the Photocatalytic Performance.

Constructing a Z-scheme heterostructure on a metal-organic framework (MOF) composite with an explicit charge transfer mechanism at the interface is considered to be an effective strategy for improving the photocatalytic performance of MOFs. Herein, an internal electric field (IEF)-induced Z-scheme heterostructure on the ZnIn2S4@NH2-MIL-125 composite is designed and fabricated by a facile electrostatic self-assembly process. Systematic investigations reveal that close interfacial contact and difference in work function between NH2-MIL-125 and ZnIn2S4 enable the formation of the IEF, which drives the Z-scheme charge transfer as revealed by the in situ irradiated X-ray photoelectron spectroscopy (ISI-XPS), photoirradiated Kelvin probe force microscope (KPFM) measurement, electron paramagnetic resonance (EPR) radical trapping experiment, as well as density functional theory (DFT) calculation; meanwhile, directions of the interfacial IEFs are determined. Benefiting from the unique merit of IEF-induced Z-scheme charge transfer, the optimized ZnIn2S4@NH2-MIL-125 composite exhibits significantly enhanced photocatalytic activity for the photoreduction of 4-nitroaniline (4-NA) to p-phenylenediamine (PPD) under visible light irradiation. This work not only provides in-depth insights for charge transfer in the IEF-induced Z scheme heterostructure but also affords useful inspirations on designing the Z-scheme MOF composite to boost the photocatalytic performance.

Effects of selenium-enriched yeast dietary supplementation on egg quality, gut morphology and caecal microflora of laying hens.

Selenium (Se) is an essential micronutrient for humans and animals and is a powerful antioxidant that can promote reproductive and immune functions. The purpose of this study was to evaluate the effects of supplemental dietary selenium-enriched yeast (SeY) on egg quality, gut morphology and microflora in laying hens. In total, 100 HY-Line Brown laying hens (45-week old) were randomly allocated to two groups with 10 replicates and fed either a basal diet (without Se supplementation) or a basal diet containing 0.2 mg/kg Se in the form of SeY for 8 weeks. The Se supplementation did not have a significant effect on egg quality and intestinal morphology of laying hens. Based on the 16S rRNA sequencing, SeY dietary supplementation effectively modulated the cecal microbiota structure. An alpha diversity analysis demonstrated that birds fed 100 mg/kg SeY had a higher cecal bacterial diversity. SeY dietary addition elevated Erysipelotrichia (class), Lachnospiraceae (family), Erysipelotrichaceae (family) and Ruminococcus_torques_group (genus; p < .05). Analysis of microbial community-level phenotypes revealed that SeY supplementation decreased the microorganism abundance of facultatively anaerobic and potentially pathogenic phenotypes. Overall, SeY supplementation cannot significantly improve intestinal morphology; however, it modulated the composition of cecal microbiota toward a healthier gut.

Genome-wide meta-analysis, functional genomics and integrative analyses implicate new risk genes and therapeutic targets for anxiety disorders.

Anxiety disorders are the most prevalent mental disorders. However, the genetic etiology of anxiety disorders remains largely unknown. Here we conducted a genome-wide meta-analysis on anxiety disorders by including 74,973 (28,392 proxy) cases and 400,243 (146,771 proxy) controls. We identified 14 risk loci, including 10 new associations near CNTNAP5, MAP2, RAB9BP1, BTN1A1, PRR16, PCLO, PTPRD, FARP1, CDH2 and RAB27B. Functional genomics and fine-mapping pinpointed the potential causal variants, and expression quantitative trait loci analysis revealed the potential target genes regulated by the risk variants. Integrative analyses, including transcriptome-wide association study, proteome-wide association study and colocalization analyses, prioritized potential causal genes (including CTNND1 and RAB27B). Evidence from multiple analyses revealed possibly causal genes, including RAB27B, BTN3A2, PCLO and CTNND1. Finally, we showed that Ctnnd1 knockdown affected dendritic spine density and resulted in anxiety-like behaviours in mice, revealing the potential role of CTNND1 in anxiety disorders. Our study identified new risk loci, potential causal variants and genes for anxiety disorders, providing insights into the genetic architecture of anxiety disorders and potential therapeutic targets.

Ferroptosis in cancer immunity and immunotherapy: Multifaceted interplay and clinical implications.

Ferroptosis is a type of cell death characterized by iron-dependent phospholipid peroxidation and reactive oxygen species overproduction. Ferroptosis induces immunogenic cell death and elicits anti-tumor immune responses, playing an important role in cancer immunotherapy. Ferroptosis suppression in cancer cells impairs its immunotherapeutic efficacy. To overcome this issue, ferroptosis inducers (FINs) have been combined with other cancer therapies to create an anti-tumor immune microenvironment. However, the ferroptosis-based crosstalk between immune and tumor cells is complex because oxidative products released by ferroptotic tumor cells impair the functions of anti-tumor immune cells, resulting in immunotherapeutic resistance. In the present article, we have reviewed ferroptosis in tumor and immune cells and summarized the crosstalk between ferroptotic tumor cells and the immune microenvironment. Based on the existing literature, we have further discussed future perspectives on opportunities for combining ferroptosis-targeted therapies with cancer immunotherapies.

Effects of dietary supplementation with tea polyphenols and probiotics on laying performance, biochemical parameters intestinal morphology and microflora of laying hens.

This study was conducted to investigate the effects of tea polyphenols (TP) and probiotics (PB) on the production performance, biochemical indices, and gut health of laying hens. A total of 400 Hy-line Brown layers (45 weeks old) were randomly assigned to 8 diet groups for 8-week feeding trial. Compared with the control basal diet (CT), dietary high dosage of TP and PB (HTP-PB) increased egg mass (P < 0.05). Supplementation with HTP-PB improved the levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and decreased the malonic dialdehyde (MDA) content (P < 0.05) without affecting the contents of immunoglobulins in the serum. The combination of HTP and PB supplementation promoted the secretion of estradiol (E2) and progesterone (PROG) compared with treatment with TP or PB alone (P < 0.05). The combined use of HTP and PB induced higher jejunal villus height (VH) than the CT group (P < 0.05). Dietary TP and PB could optimize the functional network of intestinal microflora and the interactions between the intestinal microflora and the host. Therefore, the combined use of the high dosage of TP and PB affected laying performance, improved antioxidant capacity, and promoted intestinal health, which may be associated with regulation of the intestinal microbiota.

Association between dietary flavonoid intake and depressive symptoms: A cross-sectional research.

OBJECTIVE: To investigate the relationship between dietary flavonoid intake and depression symptoms in American adults. METHODS: Data sets were obtained from the National Health and Nutrition Examination Survey (NHANES) 2007-2008, 2009-2010, and 2017-2018 survey cycles. Both males and females aged 18 years and older with complete information about dietary flavonoid intake (isoflavones, anthocyanidins, flavan-3-ols, flavanones, flavones, and flavonols), depression symptoms, and covariates were included. Logistic regression models were conducted to calculate the odds ratio (OR) of single dietary flavonoid subclass intake on depression, and the restricted cubic spline (RCS) models were utilized to explore the corresponding dose-response relationships. Additionally, we implemented the weighted quantile sum (WQS) regression and quantile g-computation (qgcomp) models to estimate the mixed effects of six flavonoid subclasses and identify the predominant types. RESULTS: After multivariable adjustments, people with higher consumption of flavanones (OR: 0.68, 95% CI: 0.52-0.90, p = 0.008), flavones (OR: 0.63, 95% CI: 0.46-0.87, p = 0.007), flavonols (OR: 0.66, 95% CI: 0.49-0.89, p = 0.008), and total flavonoids (OR: 0.69, 95% CI: 0.50-0.95, p = 0.024) had lower odds of depression symptoms. Meanwhile, significant dose-response relationships were supported by the RCS models. However, no obvious associations between isoflavones, anthocyanidins, flavan-3-ols, and the odds of suffering from depression symptoms were found by the logistic regression models and RCS models. As for the mixed effect, the WQS and qgcomp models both demonstrated that the mixture of six flavonoid subclasses was inversely related to the odds ratios of depression symptoms, and flavones, flavanones, and anthocyanidins were the top 3 contributors. CONCLUSION: Our study implied dietary flavonoid intake was associated with the decreased probability of depression symptoms in U.S. adults, among which flavones, flavanones, and anthocyanidins may occupy the predominant roles.

Relationship between dietary carotenoid intake and sleep duration in American adults: a population-based study.

OBJECTIVE: To investigate the relationship between dietary carotenoid intake and sleep duration. METHODS: Adults enrolled in the National Health and Nutrition Examination Survey (NHANES) 2007-2018 without missing information on dietary carotenoid intake (α-carotene, ß-carotene, ß-cryptoxanthin, lycopene, and lutein + zeaxanthin), sleep duration, and covariates were included. Participants' carotenoid consumption was divided into three groups by quartiles and sleep duration was grouped as short (< 7 h/night), optimal (7-8 h/night), and long (> 8 h/night). Multinominal logistic regression was constructed to examine the association between dietary carotenoid intake and sleep duration. Restricted cubic spline (RCS) regression was further utilized to explore their dose-response relationship. The weighted quantile sum (WQS) model was adopted to calculate the mixed and individual effect of 5 carotenoid sub-types on sleep duration. RESULTS: Multinominal logistic regression presented that people with higher intakes of α-carotene, ß-carotene, ß-cryptoxanthin, lycopene, and lutein + zeaxanthin were less likely to sleep too short or too long. Consistent with the findings from multinominal logistic regression, the RCS models suggested a reverse U-shaped relationship between sleep duration and carotenoid intakes. The mixed effects were also significant, where ß-cryptoxanthin and lutein + zeaxanthin were the top 2 contributors associated with the decreased risks of short sleep duration, while ß-carotene, α-carotene, and ß-cryptoxanthin were the main factors related to the lower risk of long sleep duration. CONCLUSION: Our study revealed that the American adults with optimal sleep duration were associated with more dietary carotenoid intake, in comparison to short or long sleepers.

Sexual activity, sexual satisfaction and their correlates among older adults in China: findings from the sexual well-being (SWELL) study.

Background: Sexual activity is important to the holistic health of older adults. However, the sexual lives of older adults are understudied. We aimed to investigate the prevalence and correlates of sexual activity and sexual satisfaction among older adults in China. Methods: In this multi-centre cross-sectional study, individuals aged 50 years and older were recruited from four regions in China between June 2020 and December 2022. An investigator-administered questionnaire was completed to collect information on socio-demographics, health status (general health and specific health), and sexual health characteristics. Sexual activity (including vaginal, oral, or anal sex) in the past year was treated as sexually active. Sexual satisfaction was measured using a validated five-point Likert scale. Logistic regression was used to assess correlates of sexual activity and sexual satisfaction. Findings: 3001 older adults (1182 women and 1819 men, mean age 60.3 ± 7.8 years) were recruited. Most participants were living in urban areas (1688, 56.2%), in a stable relationship (2531, 84.3%), and satisfied with life (2141, 71.3%). 46.8% of men and 40.7% of women were sexually active. Better self-reported general health status (good: aOR 0.53, 95% CI 0.34-0.82; fair: 0.47, 0.29-0.76; bad or very bad: 0.58, 0.35-0.96; versus very good), no difficulty walking upstairs (0.63, 0.41-0.97), diabetes (0.64, 0.42-0.98), and menopause (0.57, 0.36-0.92), were associated with sexual activity among women. Such an association was not found among men. Among sexually active participants, about three-quarters (men: 73.6%, women: 73.4%) were sexually satisfied. Self-reported general health status (men [good: 0.25, 0.12-0.53; fair: 0.17, 0.08-0.37; bad or very bad: 0.15, 0.06-0.34]; women [good: 0.27, 0.10-0.70; fair: 0.11, 0.04-0.30; bad or very bad: 0.11, 0.04-0.32]), life satisfaction (men: 1.73, 1.22-2.46; women: 2.23, 1.34-3.71) and talking about sexual preferences with a partner (men: 1.77, 1.23-2.56; women: 2.93, 1.69-5.09) were associated with sexual satisfaction. Interpretation: Older adults who had better health status and talked easily with their partners about their sex life were more likely to report sexual satisfaction. For women, better self-reported general health status and lack of disability were associated with sexual activity. Further research should address measures that improve sexual satisfaction, especially among sexually active older adults. Funding: This study was supported by the Natural Science Foundation of China International/Regional Research Collaboration Project [72061137001] and the Economic and Social Research Council [ES/T014547/1].

Stable Pyrene-Based Metal-Organic Framework for Cyclization of Propargylic Amines with CO2 and Detection of Antibiotics in Water.

A pyrene-based metal-organic framework, Cd2(PTTB)(H2O)2 (WYU-11), was synthesized from the tetracarboxylic pyrene ligand H4PTTB (H4PTTB = 1,3,6,8-tetrakis(3-carboxyphenyl)pyrene) and Cd(NO3)2·4H2O. Powder X-ray diffraction analysis discloses that the framework is stable in acid, base, and various organic solvent environments. WYU-11 shows excellent catalytic performance on the cyclization reaction of propargylic amines with CO2 into 2-oxazolidinones under mild conditions (60 °C, atmospheric CO2). 1H NMR studies unveiled that WYU-11 and 1,1,3,3-tetramethylguanidine (TMG) can synergistically activate the propargylic amine substrate and promote the reaction. Importantly, WYU-11 represents a rare example of noble metal-free heterogeneous catalyst that can catalyze the cyclization of CO2 with propargylic amines. In addition, by virtue of the excellent water stability and luminescence properties, WYU-11 shows excellent detection performance for sulfathiazole (STZ) and ornidazole (ODZ) in water. Investigation reveals that the coexistence of photoinduced electron transfer and internal filtering effect could reasonably explain the luminescence quenching of WYU-11 by the antibiotics.

Association between frailty and depression: A bidirectional Mendelian randomization study.

Frailty and depression were linked in observational studies, but the causality remains ambiguous. We intended to explore it using Mendelian randomization (MR). We obtained frailty genome-wide association study (GWAS) data from UK Biobank and TwinGen meta-analysis, and depression GWAS data from Psychiatric Genomics Consortium (PGC) and FinnGen (respectively recorded as PD and FD). We performed univariable and multivariable-adjusted MR with adjustments for body mass index (BMI) and physical activity (PA). Frailty was significantly associated with elevated risks of PD (OR, 1.860; 95% CI, 1.439 to 2.405; P < 0.001) and FD (OR, 1.745; 95% CI, 1.193 to 2.552; P = 0.004), and depression was meanwhile a susceptible factor for frailty (PD: ß, 0.146; 95% CI, 0.086 to 0.201; P < 0.001; and FD: ß, 0.112; 95% CI, 0.051 to 0.174; P < 0.001). This association was robust after adjustments for BMI or PA. Our study provides evidence of the bidirectional causal association between frailty and depression from genetic perspectives.

Efficacy and safety of reduced-dose chemotherapy plus immunotherapy in patients with lung squamous cell carcinoma: A real-world observational study.

BACKGROUND: Recently, chemotherapy plus immunotherapy has achieved remarkable efficacy in lung squamous cell carcinoma (LUSC). However, some patients, especially frail people, cannot tolerate full-dose chemotherapy in the real world. To reduce toxicity, appropriate dose reduction in chemotherapy is necessary. Therefore, this study aimed to demonstrate the efficacy and safety of reduced-dose chemotherapy plus immunotherapy in LUSC patients in the real world. METHODS: A real-world observational study was conducted concerning patients who received chemotherapy plus immunotherapy in our situation. The primary endpoints were objective response rate (ORR) and disease control rate (DCR), and the secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity. RESULTS: Between December 2018 and January 2022, 110 patients were enrolled, of whom 54 patients were chemotherapy reduced-dose group and 56 patients were chemotherapy standard-dose group. The ORR in the reduced-dose group is similar to standard-dose group (85.19% vs. 71.43%, p = 0.082). Similar DCR were observed (100% vs. 94.64%, p = 0.086). Median PFS was 12 months in the reduced-dose group and standard-dose group, respectively. Median OS was 15 months and 16 months in the reduced-dose group and standard-dose group, respectively. We reported a lower incidence of grade 3-4 toxicity in the reduced-dose group compared with standard-dose group (27.78% vs. 42.86%, p = 0.100). The major toxic reactions were better alleviated in the reduced-dose group than in the standard-dose group, especially in the thrombocytopenia (p = 0.044), peripheral nerve damage (p = 0.001), gastrointestinal reactions (p < 0.0001), and fatigue (p = 0.001). CONCLUSIONS: The modified regimen with attenuated doses of chemotherapy in combination with immunotherapy was effective and well tolerated in patients with LUSC. The efficacy of this modified regimen is similar to that of the full-dose regimen.

Whole transcriptome analysis reveals dysregulation of molecular networks in schizophrenia.

To characterize the regulatory relationships between different types of transcripts and the altered molecular networks in schizophrenia (SCZ), we performed a whole transcriptome study by quantifying mRNAs, long noncoding RNAs (lncRNAs), miRNAs, and circular RNAs (circRNAs) in the same individuals simultaneously. A total of 807 dysregulated genes showed differential expression in SCZ cases compared with controls. Network-based analysis revealed dysregulation of molecular networks in SCZ. Finally, integration of the transcriptome data with published data identified promising SCZ candidate genes. Our study reveals that dysregulated molecular networks and regulatory relationships between different types of transcript may have a role in SCZ.

Analysis of Inter-Eye Vault Differences After Implantable Collamer Lens (V4c) Implantation.

Purpose: The safety and stability of implantable collamer lens (ICL) implantation are closely related to the vault. We aimed to assess clinical data from patients with similar anterior segment anatomy who received ICL of the same model placed in the same position and analyze common range and factors affecting the vault inter-eye difference. Patients and Methods: A prospective study was performed, including 162 eyes of 81 patients with a bilateral ICL (V4c) implantation. Subjects were evaluated before the surgery and 1 day, 1 week, and 1 month postoperatively, and they were divided into 4 groups based on the ICL size. Bivariate correlation and multiple linear regression (stepwise) analyzed associations between vault inter-eye differences and horizontal sulcus-to-sulcus diameter, anterior chamber depth, lens thickness, ICL size, spherical equivalent, and vault. Results: One month after surgery, mean vault inter-eye differences were 74.59 ± 55.59 µm. Nearly 70% of patients presented with vault inter-eye differences lower than 100 µm. The second eye vault variance of 69% was attributed to the first eye vault. Vault inter-eye differences were positively correlated with ICL spherical equivalent (regression equation: vault inter-eye differences (µm) = 139.415 + 6.295 × ICL spherical equivalent). Vaults after ICL implantation were similar in fellow eyes, with some considerable differences. The 95% confidence interval of the vault inter-eye difference was -34.4 ~ 183.6 µm. Conclusion: In eyes with similar anterior segment anatomy, there is a 95% probability that the vault will vary from -34.4 µm to -183.6 µm when a similar ICL is implanted. These results can help surgeons to select an appropriate ICL size to achieve an ideal vault. The smaller the spherical equivalent, the larger the difference between the two vaults, which provides a reference for size in moderate myopia. ICL spherical equivalent affects and predicts vault inter-eye differences after ICL implantation.

Enhancing the anti-tumor response by combining DNA damage repair inhibitors in the treatment of solid tumors.

The anti-cancer efficacy of anti-malignancy therapies is related to DNA damage. However, DNA damage-response mechanisms can repair DNA damage, failing anti-tumor therapy. The resistance to chemotherapy, radiotherapy, and immunotherapy remains a clinical challenge. Thus, new strategies to overcome these therapeutic resistance mechanisms are needed. DNA damage repair inhibitors (DDRis) continue to be investigated, with polyadenosine diphosphate ribose polymerase inhibitors being the most studied inhibitors. Evidence of their clinical benefits and therapeutic potential in preclinical studies is growing. In addition to their potential as a monotherapy, DDRis may play an important synergistic role with other anti-cancer therapies or in reversing acquired treatment resistance. Here we review the impact of DDRis on solid tumors and the potential value of combinations of different treatment modalities with DDRis for solid tumors.

[Zi Huangjing TM Preparation Relieves Cancer-Related Fatigue During Chemotherapy: A Prospective Single-Arm Multicenter Clinical Trial].

Objective: To primarily explore the efficacy of Zi Huangjing TM preparation in patients with cancer-related fatigue (CRF) during chemotherapy. Methods: This study was designed as a prospective, single-arm, multicenter clinical trial. According to the plan of the study, patients with malignant tumors who had received at least one cycle of chemotherapy and had moderate-to-severe CRF (Piper Fatigue Scale score≥4) were enrolled. All the enrolled patients took Zi Huangjing TM preparation (2.1 g, twice a day) every day during the two subsequent cycles of chemotherapy and were followed up. During the period, the enrolled patients independently completed the Piper Fatigue Scale and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) scale, and part of their biochemical and immunological indicators were measured at the baseline, before the second cycle of chemotherapy (day 21), and before the third cycle of chemotherapy (day 42). The primary endpoint was the change in Piper Fatigue Scale scores between the baseline and day 42. Results: Eventually, 47 patients completed the entire study. After treatment, the mean score of the Piper Fatigue Scale assessed before the third cycle of chemotherapy (day 42) was 3.21±1.67, which was significantly lower than that at baseline (5.89±1.36) ( P=0.000), and the patients' CRF was significantly improved. In terms of quality of life, the patient's global quality of life, physical functions, role function, emotional function, cognitive function, and social function were significantly improved. In terms of symptom management, the patient's symptoms, such as fatigue, nausea and vomiting, insomnia, and appetite loss also significantly improved. No severe adverse reactions (grades 3 and 4) occurred during the observation period of this study. After evaluation, the adverse reactions that the patients actually had were considered to be related to chemotherapy, but unrelated to Zi Huangjing TM preparation. Conclusion: According to our preliminary investigation, Zi Huangjing TM preparation is safe and has the potential therapeutic effect of improving CRF in cancer patients during chemotherapy. However, further larger-scale randomized controlled clinical studies are needed to confirm the efficacy of Zi Huangjing TM in improving CRF.
