Germline variants and impact on lung cancer outcomes following chemotherapy: A systematic review.

BACKGROUND: Lung cancer is the primary cause of cancer deaths in the UK and globally, and the main subtypes are non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Many treatment options are available, with platinum-based chemotherapy being a key component for many patients. However, variation in survival outcomes exists among individuals of European ancestry, which makes it important to identify germline genetic variants that help guide decision-making and optimise patient treatment and outcomes. METHOD: A systematic literature search was conducted in PubMed and Web of Science for lung cancer studies investigating the impact of germline genetic variants on systemic anti-cancer therapy (SACT) outcomes in populations of European ancestry. The review was conducted according to the Preferred Reporting Items of Systematic Review and Meta-Analysis (PRISMA) and Synthesis without Meta-Analysis (SWiM) guidelines. RESULTS: A total of 20 studies were included in the review out of 4469 on NSCLC and SCLC, encompassing 3639 patients. The most thoroughly investigated area was NSCLC treated with platinum-based chemotherapy. Genetic variants associated with overall survival and/or progression-free survival included XPD Lys751Gln, XPD Asp312Asn, ERCC1 C118T, and XRCC1 Arg399Gln. For non-platinum-treated NSCLC and SCLC, there was insufficient evidence to conduct a meaningful investigation. CONCLUSION: The XPD Lys751Gln, XPD Asp312Asn, ERCC1 C118T, and XRCC1 Arg399Gln variants showed potential associations with survival outcomes among patients of European ancestry with NSCLC after platinum-based chemotherapy. To support clinical implementation, large real-world pharmacogenomics studies stratified by ancestry are needed to overcome statistical power and heterogeneity limitations.

Suicidality risk of cancer caregivers: a systematic review and meta-analysis of observational studies.

BACKGROUND: The increase in the number of global cancer cases is expected to lead to a greater caregiving burden. However, few studies have investigated the risk of suicidality among cancer caregivers. OBJECTIVE: The aim of this systematic review was to explore the risk of suicidality among cancer caregivers. METHODS: For this systematic review, a comprehensive search of the PubMed, Embase, Cochrane, Web of Science databases, PsycINFO and Scopus databases was conducted from inception to 16 July 2025. A meta-analysis was performed to determine the odds ratios (ORs) for case-control and cross-sectional studies and the adjusted hazard ratios (aHRs) for cohort studies. RESULTS: Seven studies were included (four cohort studies, one case-control study and two cross-sectional studies), and 638,188 study subjects and 4,203,957 nonexposed subjects. The meta-analyses revealed that the ORs was 1.91 (95% confidence interval [CI]: 1.46-2.49) in the case-control study, cross-sectional studies, and one cohort study which reported ORs, and the aHRs was 1.32 (95% CI: 1.16-1.50) in the three cohort studies. Caregivers of patients with highly aggressive cancers had a greater risk of suicidality (aHR = 1.66; 95% CI: 1.48-1.86). Within the first 7 years following a patient's cancer diagnosis, the risk of suicidality among caregivers remained elevated (aHR = 1.42; 95% CI: 1.04-1.94). CONCLUSION: The results indicate the need for both clinical and societal awareness to reduce the risk of suicidality among cancer caregivers, especially those with highly aggressive cancers.

3D epigenomic remodelling mediated by Foxa1 drives gemcitabine resistance in pancreatic cancer.

Gemcitabine remains a cornerstone treatment for pancreatic ductal adenocarcinoma (PDAC), yet the emergence of resistance constitutes a major clinical challenge with poorly understood epigenomic mechanisms. Here, we identified the pioneer transcription factor Foxa1 as a master regulator of gemcitabine resistance through multi-omics analysis. Mechanistically, Foxa1 drives widespread super-enhancer (SE) reprogramming and 3D genome remodelling in resistant cells, which coordinately activates the expression of key resistance genes, notably Rrm1 and Cdadc1. This is accompanied by increased chromatin accessibility, elevated H3K27ac enrichment at SEs, and enhanced Foxa1 binding at regulatory elements. Moreover, post-translational stabilization of Foxa1 via USP7-mediated deubiquitination sustains this epigenomic program. Genetic ablation of Foxa1 or specific SE regions near Rrm1 resensitizes resistant cells to gemcitabine. Building upon this mechanism, we demonstrate that bromodomain and extraterminal (BET) inhibitors, which disrupt SE function, potently reverse resistance. Notably, the clinical-stage BET inhibitor AZD5153, in combination with gemcitabine, achieves robust tumor suppression and overcomes resistance in cell-derived xenograft (CDX) models by dismantling the Foxa1-mediated resistant transcriptome and reinvigorating drug sensitivity. Our findings establish Foxa1-orchestrated enhancer reprogramming as a fundamental mechanism of gemcitabine resistance and unveil a promising epigenetic therapy to restore treatment efficacy in PDAC.

Continuous Intravenous Lidocaine for Refractory Cancer Pain in Palliative Care: A Multicenter Feasibility Study.

ObjectivesTo assess the feasibility and tolerability of continuous low-dose intravenous lidocaine infusion in patients with opioid-refractory cancer pain receiving palliative care, and to explore its potential impact on pain outcomes in real-world clinical conditions.MethodsWe conducted a multicenter, randomized, double-blind, placebo-controlled feasibility study in palliative care units to evaluate continuous intravenous lidocaine infusion in patients with opioid-refractory cancer pain. Patients were randomized to receive lidocaine (5&#x2005;mg/kg/day, increased to 8&#x2005;mg/kg/day if pain reduction was <30% after 24&#x2005;h) or placebo for 48&#x2005;h. Pain intensity was assessed using the Numeric Pain Intensity Scale, with a clinically meaningful response defined as a&#x2009;&#x2265;30% reduction from baseline at 40&#x2005;min. Secondary outcomes included pain evolution over time, neuropathic pain, symptom burden, and tolerability.ResultsThirty-five patients were included in the final analysis (18 lidocaine, 17 placebo). No significant difference was observed between lidocaine and placebo for the primary endpoint or for secondary pain outcomes. Reductions in pain intensity were observed in both groups. In the lidocaine group, 61% of patients required dose escalation to 8&#x2005;mg/kg/day. Continuous intravenous lidocaine infusion was generally well tolerated, with mostly mild adverse events and no unexpected toxicity.ConclusionIn this multicenter feasibility study, continuous low-dose intravenous lidocaine did not demonstrate a clinically meaningful analgesic benefit over placebo. As the planned sample size was not reached, the study was underpowered. These findings highlight the challenges of randomized trials in palliative care and may inform future feasibility-oriented designs.

Specific Instruments for Caregiving Competence Among Family Caregivers of Cancer Patients: A COSMIN Systematic Review of Psychometric Properties.

OBJECTIVE: To evaluate and summarize the psychometric properties of specific instruments for caregiving competence among family caregivers of cancer patients. METHODS: Systematically searched eight databases for studies published up to November 2025. The methodological quality and psychometric properties of the instruments were evaluated using COSMIN 2.0. Evidence grades were rated using the modified GRADE system (four grades: "High," "Moderate," "Low," and "Very Low"), and recommendations were formulated (Category A: recommended, Category B: potential with further validation, and Category C: not recommended). RESULTS: Seven studies were included, comprising three specific instruments: the Care Competency Scale for Family Caregivers in Home Palliative Care (CCSHPC) (n = 1), the Caregiver Caregiving Self-Efficacy Scale-Oral Cancer (CSES-OC) (n = 1), and the Caring Ability of Family Caregivers of Patients with Cancer Scale (CAFCPCS) (n = 5). Both the CCSHPC and CAFCPCS received Category B recommendations, demonstrating "adequate" content validity with evidence grades rated "very low" and "low," respectively. The CAFCPCS also shows good structural validity ("moderate") and internal consistency ("low") in some cultural contexts. The CSES-OC is a Category C recommendation, with high-quality evidence indicating "inadequate" criterion validity. CONCLUSION: Few specific instruments exist, and most did not strictly follow COSMIN guidelines. The CAFCPCS is provisionally recommended based on relative evidence superiority rather than complete psychometric validation. Further cross-cultural and localized instrument development is warranted. IMPLICATIONS FOR NURSING PRACTICE: Use well-validated specific instruments to identify strengths and weaknesses in the caregiving competencies of family caregivers of cancer patients, enabling them to deliver high-quality home-based cancer care.

Effect of Bariatric Surgery on Improvement of Retinal Microvasculature in Patients With Obesity: A Systematic Review and Meta-Analysis.

Obesity is associated with adverse retinal microvascular changes, including narrower central retinal arteriolar equivalent (CRAE), wider central retinal venular equivalent (CRVE) and lower arteriovenous ratio (AVR). Although bariatric surgery improves cardiometabolic risk, its effect on retinal microvascular calibre remains uncertain. We systematically searched the Cochrane Library, PubMed, ScienceDirect and Scopus up to June 2026. Prospective cohort studies reporting CRAE, CRVE or AVR before and after bariatric surgery in patients with obesity were included. Risk of bias was assessed using the Newcastle-Ottawa Scale. Pooled mean differences (MD) with 95% confidence intervals (CI) were calculated using a random-effects model. Eight prospective cohort studies including 283 patients were included. Seven studies contributed to the CRAE and CRVE analyses, and seven contributed to the AVR analysis. Bariatric surgery was associated with a significant increase in CRAE (MD&#x2009;=&#x2009;+4.02&#x2009;&#x3bc;m, CI [0.26-7.78], p&#x2009;=&#x2009;0.04). Sensitivity analysis excluding one study showed a stronger and more consistent effect (MD&#x2009;=&#x2009;+5.41&#x2009;&#x3bc;m, CI [4.59-6.22], p&#x2009;<&#x2009;0.01). CRVE significantly decreased after surgery (MD&#x2009;=&#x2009;-6.75&#x2009;&#x3bc;m, CI [-7.42 to -6.07], p&#x2009;<&#x2009;0.01), while AVR significantly increased (MD&#x2009;=&#x2009;+0.03, CI [0.02-0.05], p&#x2009;<&#x2009;0.01). Sensitivity analyses suggested that the direction of effect was generally robust, although between-study heterogeneity was present. Bariatric surgery may be associated with favourable retinal microvascular changes in patients with obesity, reflected by increased CRAE and AVR and decreased CRVE.

Delphi study robot consenso: Strategies for the implementation of robotic surgery in general surgery in the Spanish hospital network.

INTRODUCTION: The implementation of robotic surgery in public hospitals presents multiple logistical, educational, and organizational challenges. In the absence of unified guidelines, a national consensus is required to optimize its safe and efficient adoption. This study aimed to establish a set of consensus-based and measurable recommendations for the implementation of robotic surgery programs in hospitals within the Spanish National Health System, based on the experience of centres with established robotic programs and intended to serve as guidance for hospitals that are initiating or planning their implementation. METHODS: A national Delphi study was conducted with the participation of robotic surgery experts from 26 public hospitals. The expert panel was composed exclusively of digestive surgeons with experience in robotic surgery. Three iterative rounds of expert panel evaluation were conducted between March 2024 and March 2025. The questions were grouped into five thematic blocks. Consensus was defined as an agreement level of &#x2265;66.7%. Kendall's W coefficient was used to assess concordance. RESULTS: High levels of consensus were achieved on key aspects related to infrastructure, structured training, cost evaluation, and quality assurance mechanisms. Areas of disagreement were also identified, such as the need for a dedicated anaesthesiologist, purchase of accessory instruments during the initial phase, and official accreditation pathways. CONCLUSIONS: This study provides a guideline for developing a national robotic surgery strategy focused on patient safety, program sustainability, and standardized training of surgical teams. These recommendations can guide hospitals at different stages of robotic technology adoption. Given that the consensus was reached from an exclusively surgical perspective, the recommendations focus on patient safety, program sustainability, and standardized training of the surgical team, and should be interpreted in an adaptable manner according to each centre's context, case volume, and available resources.

The Neurological Impact of Metabolic and Bariatric Surgery: A Systematic Review of Post-Operative Neuropathic and Non-Neuropathic Complications.

Metabolic and bariatric surgery achieves durable weight loss and meaningful improvement in obesity-related comorbidities yet carries a risk of neurological complications that remains under-recognised in routine clinical practice. This systematic review, registered with PROSPERO (CRD42024591611) and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, searched MEDLINE, Embase, Emcare, CINAHL and Cochrane databases through September 2023 to evaluate the incidence, spectrum, timing, pathophysiology and management of post-operative neurological complications. Twelve studies comprising over 5000 patients were included. Reported incidence ranged from 1.4% to 16%, with peripheral neuropathy the most frequent manifestation. Mononeuropathies, particularly carpal tunnel syndrome, were prominent in several cohorts, while central complications including Wernicke encephalopathy occurred less commonly but with considerably greater severity. Thiamine deficiency was the predominant aetiological factor. Onset varied from days to several years postoperatively, with early presentations typically compression-related and later ones nutritionally mediated. Outcomes were generally favourable with early intervention, though severe or delayed cases were associated with persistent neurological deficits and occasional mortality. Neurological complications after bariatric surgery are heterogeneous and largely preventable, and structured post-operative follow-up with consistent adherence to nutritional supplementation remains central to reducing long-term harm.

Identification of CD55 as a downstream factor of EP4 receptor signaling in colorectal cancer cells.

Prostaglandin E2 (PGE2) signaling through the E-type prostanoid 4 (EP4) receptor has been implicated in the pathophysiology of colorectal cancer (CRC). We herein identified decay-accelerating factor, also known as CD55, as a novel CRC-associated downstream factor of the EP4 receptor. The integration of transcriptomic profiling of PGE2-stimulated HCA-7 human colon cancer cells with analyses of cancer genomic databases predicted CD55 as a potential EP4 receptor-regulated target. Inhibitor-based experiments showed the induction of CD55 after a PGE2 stimulation required the EP4 receptor and Gi protein in HCA-7 cells, whereas protein kinase A signaling was dispensable. In combination with a toxicogenomic database analysis, p38 mitogen-activated protein kinase (MAPK) was identified as the predominant effector connecting the EP4 receptor to CD55 upregulation. A single-cell RNA-seq re-analysis of human CRC tissues revealed CD55 upregulation and p38 MAPK-related gene set enrichment in epithelial cells expressing the EP4 receptor, suggesting that this induction mechanism may operate in a subset of epithelial cells in clinical specimens. Collectively, these results delineate a PGE2/EP4 receptor/Gi protein/p38 MAPK signaling axis that induces CD55 expression in HCA-7 cells and epithelial tumor cells, provide new mechanistic clues for understanding the regulation of complement regulatory molecule CD55 expression by prostaglandin signaling.

Opposing kinase signaling may underlie the inverse relationship between cancer and Alzheimer's disease.

Cancer and Alzheimer's disease (AD) are leading causes of mortality and exhibit an inverse relationship, where AD patients have reduced cancer risk and vice versa. However, the molecular basis of this relationship remains poorly understood. We reanalyzed published proteomic and phosphoproteomic datasets to investigate this relationship. Differentially abundant proteins were identified in lung adenocarcinoma and glioblastoma samples relative to controls and compared with proteins altered in AD brains, revealing 37 proteins with opposing abundance patterns. Protein-protein interaction and pathway analyses revealed enrichment in kinase signaling and phosphorylation pathways. Phosphoproteomic analysis identified 52 differentially phosphorylated sites with opposing patterns, while kinase-substrate enrichment analysis identified 44 kinases with opposing inferred activity profiles. Integration of kinase activity and phosphosite data identified 29 kinase-phosphosite pairs, including 4 prioritized pairs with opposing patterns relevant to both diseases. Across seven independent cancer cohorts, 17 of 20 statistically significant phosphosite-cohort comparisons (85%) were concordant with the discovery findings, supporting reproducibility of the prioritized phosphosites. Together, these findings highlight opposing kinase signaling as a prominent feature of the inverse relationship and suggest potential biomarkers and therapeutic targets. This study provides a novel systems-level framework for investigating inverse relationships, supported by an R Shiny application for data exploration (https://advscancer.shinyapps.io/advscancer/). SIGNIFICANCE: This study presents an integrated proteomic and phosphoproteomic framework for investigating the inverse relationship between cancer and Alzheimer's disease (AD). By integrating differential protein abundance, phosphosite phosphorylation, inferred kinase activity, and curated kinase-substrate relationships, we identified opposing signaling patterns and prioritized four kinase-phosphosite pairs. Independent evaluation across seven CPTAC cancer cohorts supported the reproducibility of the prioritized phosphosite patterns. These findings provide insight into molecular processes potentially associated with the inverse relationship between cancer and AD, identify candidate biomarkers and therapeutic targets, and demonstrate the value of systems-level, data-driven approaches for investigating shared and opposing disease processes.

Regional and statewide hysterectomy-corrected endometrial cancer incidence and five-year relative survival in Texas.

BACKGROUND: Rising endometrial cancer (EC) incidence nationwide, particularly among Hispanic women, and high prevalence of risk factors such as obesity and comorbidities in Texas, motivated us to estimate EC incidence rates (IRs) and survival by age (<50 years/ early-onset, &#x2265;50 years/late-onset), race-ethnicity (Non-Hispanic-White [NHW], -Black [NHB], Hispanic), histology (endometrioid, non-endometrioid), and area-based socioeconomic (SES) factors across Texas Health Service Regions (HSRs). STUDY DESIGN: Between 2000 and 2019, a total of 42,571 women (20-79 years) with EC were reported from Texas within the Surveillance, Epidemiology, and End Results Program. IRs and 5-year relative survival were calculated using SEER*Stat. IRs were corrected for hysterectomy using Behavioral Risk Factor Surveillance System data. RESULTS: Statewide EC IRs rose from 38.5 (2000-2009) to 44.5 (2010-2019), with the highest increase in the Upper-South (42.6 to 53.8). Across HSRs, Upper-South consistently had higher IRs among women <&#x202f;50 (13.9) and &#x2265;&#x202f;50 years (112.7). Among those <&#x202f;50 years, Hispanics had the highest IRs (12.4), predominantly endometrioid tumors, whereas in women &#x2265;&#x202f;50 years, NHB had the highest IRs (119.2) with a large proportion of non-endometrioid tumors. IRs were higher in areas with lower poverty, and higher education, income, and urbanization. Associations with unemployment were mixed. Worse survival outcomes were observed among NHBs, non-endometrioid, advanced-stage, and lower SES. Central Texas had more favorable survival outcomes compared to other HSR. CONCLUSION: EC IRs and survival rates in Texas largely mirror national trends, with regional differences likely reflecting sociodemographic and histologic distributions.

Mindfulness and Sex Education for Sexual Dysfunction in Breast Cancer Survivors: Mediators and Moderators of Treatment Outcome.

Mindfulness-based cognitive therapy (MBCT) and supportive-expressive sex education therapy (STEP) are effective group treatments for sexual dysfunction after breast cancer (BrCa). We explored mediators and moderators of outcomes following the 8-week groups. BrCa survivors (n&#x2009;=&#x2009;116, mean age&#x2009;=&#x2009;49.9&#x2009;&#xb1;&#x2009;9.5) were randomized to group and completed measures before, immediately after, and 6&#x2009;months after treatment. Mediators assessed were changes in depression, chronic pain acceptance, pain catastrophizing, and trait mindfulness. Potential moderators included age, treatment expectations, baseline mental health, cancer treatment duration, use of chemotherapy, and adjuvant endocrine therapy. Longitudinal mediation and moderation were assessed using linear mixed models. Increases in pain acceptance mediated improvements in sexual desire and reductions in both sexual distress and vaginal pain. Decreases in pain catastrophizing mediated improvements in sexual distress. Higher expectations for treatment led to greater reductions in sexual distress. Those with low baseline anxiety showed greater improvements in desire and distress. Low baseline depression predicted greater improvements in desire, but only in the STEP arm. Older STEP participants improved significantly more than younger STEP participants. Cancer-related treatment variables, and the impact of adjuvant endocrine therapy, had differential effects on outcomes based on the treatment arm of the study. In conclusion, treatments aimed at improving pain acceptance and pain catastrophizing are likely to promote improvements in sexual health among BrCa survivors, and factoring in patients' expectations about treatment improvements, depression and anxiety, age, duration of cancer treatment, chemotherapy, and adjuvant hormonal therapy may help to guide treatment recommendations for sexual dysfunction.

Mechanisms linking the gut microbiota to colorectal cancer development and progression.

Colorectal cancer remains a leading cause of global cancer mortality, with a concerning rise in early-onset cases driven by complex interactions between environmental exposures, lifestyle factors, and host genetics. Mounting evidence indicates that gut microbiota dysbiosis critically modulates this oncogenic process, acting as an active participant rather than a passive bystander. This review systematically synthesizes the dichotomous roles of the intestinal microbiome in colorectal tumorigenesis through the conceptual framework of the driver-passenger model. We discuss how early initiating driver bacteria, such as Polyketide synthase-positive Escherichia coli and enterotoxigenic Bacteroides fragilis, compromise mucosal barriers, induce chronic mucosal inflammation, and inflict direct genomic instability. As the local tumor microenvironment undergoes profound metabolic remodeling, opportunistic passenger pathogens, notably Fusobacterium nucleatum, become enriched, further promoting cellular proliferation and facilitating tumor immune evasion. Conversely, protective commensals, exemplified by Clostridium butyricum and Streptococcus thermophilus, exert robust tumor-suppressive effects through multifaceted mechanisms. These beneficial microbes actively antagonize malignant progression by redirecting tumor metabolic fluxes toward oxidative stress, orchestrating deep epigenetic reprogramming, and degrading core oncoproteins to reverse chemoresistance. Transitioning from fundamental mechanisms to clinical application, we evaluate a comprehensive spectrum of microbiota-targeted interventions, encompassing non-invasive diagnostic biomarkers, fecal microbiota transplantation, engineered bacteria, phage therapy, and postbiotics. Finally, we critically address the formidable translational challenges associated with microbial heterogeneity, long-term safety, and regulatory standardization, aiming to provide a balanced perspective on integrating microbiome-based strategies into next-generation precision oncology for colorectal cancer.

Efficacy and safety of postoperative chewing gum for gastrointestinal recovery in children undergoing surgery: an updated systematic review and meta-analysis.

Chewing gum may stimulate gut motility through a "sham feeding" mechanism, but evidence in children is limited. We performed an updated systematic review and meta-analysis of randomized controlled trials comparing chewing gum plus usual care versus usual care alone in patients younger than 18 years undergoing any surgery. We searched five databases through June 2025. Primary outcomes were the time to first flatus, time to first defecation, and postoperative length of stay (LOS). Certainty was assessed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Ten studies (n&#x2009;=&#x2009;649) were included: abdominal surgery (5), spinal fusion (3), and tonsillectomy (2). Chewing gum may result in little to no difference in the time to first flatus (MD&#x2009;-&#x2009;3.58&#xa0;h, 95% CI&#x2009;-&#x2009;8.08 to 0.91) or first defecation (MD&#x2009;-&#x2009;3.23&#xa0;h, 95% CI&#x2009;-&#x2009;6.63 to 0.18), both with low certainty. LOS evidence was very uncertain (MD&#x2009;-&#x2009;0.18 days, 95% CI&#x2009;-&#x2009;0.70 to 0.33). Subgroup analyses suggested shorter LOS after abdominal surgery (MD&#x2009;-&#x2009;0.60 days, 95% CI&#x2009;-&#x2009;1.99 to 0.79) but not after spinal fusion (MD 0.10 days, 95% CI&#x2009;-&#x2009;0.29 to 0.50; p for interaction&#x2009;=&#x2009;0.0362). The benefits of postoperative chewing gum in children remain uncertain, with potential surgery-specific differences in LOS warranting investigation.

Dexamethasone as an adjuvant to continuous erector spinae plane block for postoperative analgesia after video-assisted thoracoscopic surgery for pulmonary nodule surgery: a randomized controlled trial.

BACKGROUND: While dexamethasone is proven to enhance single-shot erector spinae plane block (ESPB), its role as an adjuvant in continuous ESPB catheters is unclear. This randomised controlled trial evaluated whether adding dexamethasone to ropivacaine improves analgesia after video-assisted thoracoscopic surgery (VATS). METHODS: 85 patients undergoing VATS with continuous ESPB were randomised to receive postoperative infusion of either 0.2% ropivacaine(C-ESPB group) or ropivacaine with 10&#x2009;mg dexamethasone(D&#x2009;+&#x2009;C-ESPB group). The primary outcome was resting pain visual analog scale (VAS)at 12&#x2009;h postoperatively, while secondary outcomes included QoR-15 scores, tramadol consumption, time to first analgesic requirement, postoperative adverse events, 3-month incidence of chronic pain, catheter-related complications, pain intensity at other times, and hospital stay. RESULTS: The D&#x2009;+&#x2009;C-ESPB group had significantly lower resting pain at 12&#x2009;h [2.56 (1.03) vs 3.24 (1.21), mean difference -0.680, p&#x2009;=&#x2009;0.006]; and lower coughing pain at 12&#x2009;h [4.60 (1.48) vs 5.69 (1.35), mean difference 1.086, p&#x2009;<&#x2009;0.001], with analgesic superiority sustained through 72&#x2009;h. Quality of Recovery-15 scores were higher at 12&#x2009;h [124.70 (12.48) vs 117.26 (12.24); mean difference -7.436, p&#x2009;=&#x2009;0.007] and 48&#x2009;h [141.60 (5.51) vs 138.98 (6.64); mean difference -2.628, p&#x2009;=&#x2009;0.050]; Total tramadol consumption over 72&#x2009;h was markedly reduce [0 (0,100) vs 100 (75,100), z&#xa0;=&#xa0;-3.807, p&#x2009;<&#x2009;0.001], and hospital stay was shorter [Mean (SD) 6.09 (1.34)&#xa0;d vs 6.93 (1.55)d, p&#x2009;<&#x2009;0.001]. The intervention did not, however, alter the 3-month incidence of chronic postsurgical pain (31% vs 34%, p&#x2009;=&#x2009;0.756). CONCLUSION: Dexamethasone significantly enhances the analgesic efficacy of continuous ESPB, improving early pain control, recovery quality, and opioid-sparing after VATS, but does not reduce the incidence of chronic persistent surgical pain.

The gut microbiota-obesity axis in the pathogenesis and prognosis of breast cancer.

BACKGROUND: Breast cancer (BC) remains a major global health concern, accounting for 11.7% of all cancer cases and ranking as the second leading cause of female cancer-related deaths worldwide. Increasing evidence highlights the interplay between&#xa0;gut microbiota (GM) dysbiosis and obesity-associated metabolic dysfunction in BC progression. This review aims to elucidate&#xa0;the role of GM in obese patients with BC. METHODS: A systematic literature search was conducted in PubMed and Web of Science databases for publications from July 2015 to January 2025. Search terms combined BC, GM, obesity, dysbiosis, immunity, and microbiome. Article selection prioritized studies investigating microbial alterations in BC patients, mechanistic links between obesity and cancer progression, and GM-targeted interventions. Both original studies and authoritative reviews were included, supplemented by manual reference screening. DISCUSSION: Obesity may trigger systemic inflammation, altered adipokine secretion, and disrupted steroid hormone metabolism via gut-derived &#x3b2;-glucuronidase activity, thereby exacerbating BC occurrence and recurrence. GM dysbiosis-driven metabolites such as branched-chain amino acids (BCAAs) and short-chain fatty acids (SCFAs) can activate oncogenic signaling pathways and immunosuppressive myeloid-derived suppressor cells (MDSCs), fostering tumor immune evasion. Conversely, dietary interventions, probiotics, and fecal microbiota transplantation (FMT) can alleviate dysbiosis, strengthen gut barriers, and restore anti-tumor immunity, improving chemotherapy response and reducing recurrence. However, challenges persist in deciphering BC subtype-related microbial signatures and optimizing microbiota-targeted therapies. CONCLUSION: Future longitudinal studies are needed to clarify causal relationships, validate microbial biomarkers, and translate preclinical findings into clinical applications. Addressing the gut-breast axis may offer transformative potential for precision oncology in obesity-driven BC.

Glaucoma filtering surgery combined with phacoemulsification in the era of new aqueous humor filtration devices: A systematic review.

We evaluate the efficacy and safety of filtering glaucoma surgeries combined with phacoemulsification (PCE)-including new aqueous humor drainage devices-compared to standalone procedures. We performed a systematic search up to March 23, 2025, including all comparative studies assessing trabeculectomy (TRAB), non-penetrating deep sclerectomy (NPDS), Xen&#xae; Gel Stent (XEN), or Preserflo&#xae; MicroShunt (PMS) combined with PCE, versus the same surgery alone. Key exclusion criteria include inadequate follow-up (less than 12-month), absence of a defined success criterion, more than 50% of loss to follow-up at 12-month, and lens extraction performed without PCE. Main outcome was surgical success at &#x2265;&#x202f;12 months. Secondary outcomes included intraocular pressure (IOP) reduction, decrease in hypotensive medications, and rates of complications. A total of 27 studies were included for analysis. Among studies comparing TRAB/PCE with standalone TRAB, half reported similar success rates, while others favored standalone TRAB, particularly using strict IOP thresholds. Safety profiles were comparable. For NPDS/PCE, data mostly showed equivalent outcomes versus standalone NPDS, with comparable safety. In studies on XEN/PCE and PMS/PCE, results suggested similar rates of surgical success, efficacy in IOP and medication reduction, and safety compared to their stand-alone procedures. Small differences occasionally favored standalone procedures under stricter success definitions. Current evidence suggests that combined filtering glaucoma surgery provides long-term efficacy and safety comparable to standalone, though some subgroups and outcome thresholds may slightly favor standalone approaches. The limited availability of high-quality prospective trials underscores the need for further large-scale robust studies.

Quality of life and gender identity in females with congenital adrenal hyperplasia after genital restoration surgery: A single-center experience.

BACKGROUND: Legislation restricting surgical interventions in children with differences of sex development (DSD) has intensified debate about female genital restoration surgery (FGRS) in patients with congenital adrenal hyperplasia (CAH). Long-term patient-reported outcomes are needed regarding the optimal timing of surgery. OBJECTIVE: We aimed to assess health-related quality of life (HRQoL), gender identity, and family satisfaction regarding surgical timing and outcome in females with CAH following genital restoration surgery. STUDY DESIGN: Cross-sectional survey of CAH patients who underwent surgery between January 2007 to December 2016 at our institution. Validated instruments (KINDL questionnaire for HRQoL, Utrecht Gender Dysphoria Scale, UGDS) and structured telephone interviews were employed. RESULTS: Data on HRQoL was available for 25 patients (self- and/or parent-reported) out of 56 eligible patients (45% response rate). Median age at first surgery was 6 months (range: 3-137 months). Patients' age at time of participation ranged from 2 to 28 years. All had 21-hydroxylase deficiency (92% salt-wasting form) with Prader grades ranging from II-V. Wound dehiscence requiring secondary suturing occurred in 15% of patients with primary surgery at our center, while only one (4%) patient developed vaginal stenosis after early primary vaginoplasty. Two additional patients (8%) with prior outside surgery required vaginal revision after FGRS at age 12. HRQoL scores were comparable to healthy reference populations across most age groups. Children aged 3-6 and adolescents and young adults showed no significant difference from reference values, while children aged 7-13 showed a slight elevation. None of five patients &#x2265;14 years demonstrated gender dysphoria (all UGDS scores <40, threshold &#x2265;40). 14 patients and families were also interviewed by telephone. All preferred early surgical timing. No family expressed regret about the decision or preferred delayed surgery. DISCUSSION: This study provides validated intermediate-term patient- and parent-reported outcomes after FGRS in CAH. Key limitations include the small sample size, single-center design, and young age of most patients. Selection bias may exist, though participating families included those who underwent revision surgery. The absence of a non-operated comparison group reflects current clinical reality, as nearly all CAH patients with urogenital sinus underwent surgical correction. CONCLUSIONS: Females with CAH reported normal HRQoL and a comfortable female gender identity after early FGRS. The patients and their families expressed a preference for early surgery. However, there is need for longer-term follow-up to assess sexual function and reproductive outcomes as well comparison of outcomes with a non-operated group.
