Clinical characteristics and survival of esophageal cancer patients: annual report of the surgical treatment in Shanghai Chest Hospital, 2017.

Background: Esophageal cancer remains a significant burden of lethal cancers worldwide, particularly in China. This is an annual report of Shanghai Chest Hospital (SCH) on surgical treatment for esophageal cancer patients in 2017. Methods: All patients who received surgical treatment for esophageal cancer at SCH in 2017 were given a detailed summary of clinical information based on the database of SCH. Kaplan-Meier method was used to present their survival, subgroup analyses, and multivariate Cox regression analysis were used to estimate the potential risk factors for prognosis. Results: In 2017, a total of 663 patients received surgical treatment (628 esophagectomies and 35 endoscopic resections) for esophageal cancer at SCH. Of the patients who underwent esophagectomy, 292 patients received perioperative treatment, majority of which was postoperative treatment (47.9%). Only 69 (10.4%) patients received preoperative treatment. Minimally invasive techniques were used in 444 (70.7%) patients and robotic-assisted esophagectomies were used in 130 (20.7%) patients. Complete resection (R0) was achieved in 90.3% of esophagectomy patients. The 5-year overall survival (OS) rate after esophagectomy was 52.5%. Conclusions: The 5-year OS of patients with esophageal cancer can reach 52.5% after surgical treatment in 2017 at SCH. The exact beneficiaries of neoadjuvant therapy are still unclear in the 2017 cohort.

Occurrence and recovery of vocal cord paralysis after minimally invasive McKeown esophagectomy, risk factors, and clinical outcome.

BACKGROUND: This study aimed to observe the occurrence of recurrent laryngeal nerve injury after McKeown esophagectomy for esophageal squamous cell carcinoma, as well as its recovery and influencing factors within 7 months after surgery. METHODS: From July 2020 to July 2021, among all patients who underwent minimally invasive McKeown esophagectomy, 90 patients who developed vocal cord paralysis after surgery were included in the study. These patients underwent endoscopic vocal cord function assessment every 1 to 2 months and continued until 7 months postoperatively. RESULTS: Among all 388 patients undergoing esophagectomy, 23.2% (90/388) of patients suffered postoperative vocal cord paralysis. Left, right, and bilateral injuries were confirmed in 73 (81.1%), 12 (13.3%), and 5 patients (5.6%), respectively. With a median recovery time being 183 days, the cumulative overall recovery rate was 65.4% at 7 months, 68.6% for the left side, 55.6% for the right, and 20.0% for bilateral injuries. In multivariable analysis, cervical paraoesophageal lymph node dissection and conventional thoracoscopic-assisted esophagectomy were demonstrated to be independent risk factors associated with non-recovery of vocal cord paralysis. CONCLUSIONS: After intensive endoscopic follow-up, a cumulative vocal cord paralysis recovery rate of 65.4% within 7 months was observed in patients after minimally invasive McKeown esophagectomy. Cervical paraoesophageal lymph node dissection and conventional thoracoscopic-assisted esophagectomy were demonstrated to be risk factors hindering vocal cord paralysis recovery.

Brood success of sex-role-reversed pheasant-tailed jacanas: the effects of social polyandry, seasonality, and male mating order.

Multiple mating by avian females may increase hatching and overall brood success; however, reproductive effort and parental investment are costly, and females may be gradually depleted, with lowered outputs over time. Thus, males in social polyandry systems may differ greatly in their reproductive gains. In the present study, we investigated the reproductive outputs of social polyandrous and sex-role-reversed pheasant-tailed jacanas, Hydrophasianus chirurgus, to assess the effects of polyandry, seasonality, and male mating order on breeding success. Female jacanas produced multiple clutches, either by leaving two or more clutches with an individual male (22%), or by mating with two or more males (78%). The polyandrous females laid both the first and second clutches earlier and showed a breeding period more than twice as long as that of monandrous females. Both polyandry and seasonality affected the fate of a clutch, where clutches from polyandrous females and the early season had higher hatching and brood success rates, but the number of polyandrous females declined over the season. Polyandrous females not only laid more clutches and eggs, and gained more hatchlings and fledglings, but also achieved higher per-clutch outputs and hatching rates than monandrous females. In polyandry groups, males gained higher total hatchlings and fledglings, although not total clutches or eggs, than males in monandry or bi-andry groups. Moreover, males in polyandry groups achieved higher hatchlings and fledglings per clutch and higher hatching and brood success rates. In polyandry groups, the first-mating males obtained more clutches, eggs, and hatchlings; however, they did not have higher success rates, nor total fledglings and per-clutch outputs, than males who mated later. Overall, the results indicate a selective advantage of polyandry for the jacanas studied, particularly in the early breeding season. This advantage, however, differs both between the sexes and intra-sexually, suggesting strong connections with certain ecological/environmental conditions in addition to the jacanas' own quality.

Acute, long-term or non-vincristine-induced peripheral neuropathy among non-Hodgkin lymphoma survivors: Symptoms, daily activities, functional status, and quality of life.

PURPOSE: This study aimed to explore the incidence and severity of vincristine-induced peripheral neuropathy (VIPN) in non-Hodgkin lymphoma (NHL) survivors (primary aim) and its impact on daily life by comparing common cancer symptoms, functional status, and quality of life (QoL) among survivors with acute, long-term, and non-VIPN (secondary aim). METHODS: This cross-sectional study examined 144 NHL survivors. Standardized questionnaires were used to assess common cancer symptoms, functional status, and QoL with the European Organization for the Research and Treatment of Cancer - Quality of Life Questionnaire (EORTC-QLQ-C30). VIPN (Chemotherapy-Induced Peripheral Neuropathy) status was classified using EORTC-QLQ-CIPN20. A self-designed interference scale was developed to determine the impact of the VIPN on daily activities. The Kruskal-Wallis test and Spearman rank correlation were used in this study. RESULTS: Among the survivors of acute and long-term VIPN, the highest incidences and most severe symptoms were found for hand numbness and foot cramps. A significant moderate correlation was found between disturbances in daily activities and acute or long-term VIPN, including gait changes, going up or down the stairs, and imbalance-related falls. Acute and long-term VIPN survivors showed worse symptoms (fatigue, insomnia, and constipation) and lower QoL than non-VIPN survivors did. In acute VIPN, social function was significantly affected, whereas in long-term VIPN, emotional and cognitive functions were affected. CONCLUSION: Numbness and cramps should be addressed in survivors of acute and long-term VIPN. Preventing falls is recommended for NHL survivors with VIPN, and psychological support is suggested for long-term VIPN survivors.

The Relationship between Dynapenic Abdominal Obesity and Fall: A Systematic Review and Meta-Analysis of 15,506 Middle to Older Adults.

BACKGROUND: The main objective of this study was to investigate the risk of falls among middle-aged and older adults with dynapenic abdominal obesity. METHODS: A systematic literature search was conducted to review and analyze relevant studies. Dynapenia was measured by handgrip strength, and abdominal obesity was measured by waist circumference. The search keywords included "older people" OR "elderly" OR "middle age" AND "dynapenia" AND "abdominal obesity" AND "fall." The search was not limited by time and included articles published up until April 2023. The literature search process followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, involving extraction and examination of the retrieved relevant articles. Systematic literature searches were performed in databases such as Embase, PubMed, MEDLINE, CINAHL, and Cochrane Library. RESULTS: This study collected a total of eight articles with a combined sample size of 15,506 participants. The findings revealed that the average follow-up period for falls was 6.6 years (SD = 3.67). The overall results of the study showed that individuals with dynapenic abdominal obesity had a higher risk of falls compared to those without dynapenic abdominal obesity (RR = 6.91, 95% CI: 5.42-8.80). Subgroup analysis demonstrated that both prospective studies (HR = 6.61; 95% CI = 4.29-10.20) and retrospective studies (OR = 7.37; 95% CI = 5.13-10.59) consistently found a higher risk of falls among individuals with dynapenic abdominal obesity. However, there was no significant difference in fall risk between community-dwelling individuals with dynapenic abdominal obesity and hospitalized individuals with dynapenic abdominal obesity (Qbetweenx2 = 0.29, p = 0.58). Additionally, there was no difference in fall risk between individuals with dynapenic abdominal obesity residing in Europe and Latin America compared to those residing in Asia (Qbetweenx2 = 0.05, p = 0.81). It was worth noting that male individuals with dynapenic abdominal obesity had a higher risk of falls compared to females (Qbetweenx2 = 4.73, p = 0.03). CONCLUSIONS: Empirical studies have demonstrated that individuals with dynapenic abdominal obesity have a higher risk of falls. Therefore, healthcare professionals should conduct early fall risk assessments and develop effective preventive strategies specifically targeted at individuals with dynapenic abdominal obesity.

Enhancing Prediction for Tumor Pathologic Response to Neoadjuvant Immunochemotherapy in Locally Advanced Esophageal Cancer by Dynamic Parameters from Clinical Assessments.

To develop accurate and accessible prediction methods for assessing pathologic response following NICT prior to surgery, we conducted a retrospective study including 137 patients with esophageal squamous cell carcinoma (ESCC) who underwent surgery after two cycles of NICT between January 2019 and March 2022 at our center. We collected clinical parameters to evaluate the dynamic changes in the primary tumor. Univariate and multivariate analyses were performed to determine the correlations between these parameters and the pathologic response of the primary tumor. Subsequently, we constructed prediction models for pCR and MPR using multivariate logistic regression. The MPR prediction Model 2 was internally validated using bootstrapping and externally validated using an independent cohort from our center. The univariate logistic analysis revealed significant differences in clinical parameters reflecting tumor regression among patients with varying pathologic responses. The clinical models based on these assessments demonstrated excellent predictive performance, with the training cohort achieving a C-index of 0.879 for pCR and 0.912 for MPR, while the testing cohort also achieved a C-index of 0.912 for MPR. Notably, the MPR prediction Model 2, with a threshold cut-off of 0.74, exhibited 92.7% specificity and greater than 70% sensitivity, indicating a low rate of underestimating residual tumors. In conclusion, our study demonstrated the high accuracy of clinical assessment-based models in pathologic response prediction, aiding in decision-making regarding organ preservation and radiotherapy adjustments after induction immunochemotherapy.

Human-Like Artificial Intelligent System for Predicting Invasion Depth of Esophageal Squamous Cell Carcinoma Using Magnifying Narrow-Band Imaging Endoscopy: A Retrospective Multicenter Study.

INTRODUCTION: Endoscopic evaluation is crucial for predicting the invasion depth of esophagus squamous cell carcinoma (ESCC) and selecting appropriate treatment strategies. Our study aimed to develop and validate an interpretable artificial intelligence-based invasion depth prediction system (AI-IDPS) for ESCC. METHODS: We reviewed the PubMed for eligible studies and collected potential visual feature indices associated with invasion depth. Multicenter data comprising 5,119 narrow-band imaging magnifying endoscopy images from 581 patients with ESCC were collected from 4 hospitals between April 2016 and November 2021. Thirteen models for feature extraction and 1 model for feature fitting were developed for AI-IDPS. The efficiency of AI-IDPS was evaluated on 196 images and 33 consecutively collected videos and compared with a pure deep learning model and performance of endoscopists. A crossover study and a questionnaire survey were conducted to investigate the system's impact on endoscopists' understanding of the AI predictions. RESULTS: AI-IDPS demonstrated the sensitivity, specificity, and accuracy of 85.7%, 86.3%, and 86.2% in image validation and 87.5%, 84%, and 84.9% in consecutively collected videos, respectively, for differentiating SM2-3 lesions. The pure deep learning model showed significantly lower sensitivity, specificity, and accuracy (83.7%, 52.1% and 60.0%, respectively). The endoscopists had significantly improved accuracy (from 79.7% to 84.9% on average, P = 0.03) and comparable sensitivity (from 37.5% to 55.4% on average, P = 0.27) and specificity (from 93.1% to 94.3% on average, P = 0.75) after AI-IDPS assistance. DISCUSSION: Based on domain knowledge, we developed an interpretable system for predicting ESCC invasion depth. The anthropopathic approach demonstrates the potential to outperform deep learning architecture in practice.

Subcellular Distribution of BALF2 and the Role of Rab1 in the Formation of Epstein-Barr Virus Cytoplasmic Assembly Compartment and Virion Release.

Epstein-Barr virus (EBV) replicates its genome in the nucleus and undergoes tegumentation and envelopment in the cytoplasm. We are interested in how the single-stranded DNA binding protein BALF2, which executes its function and distributes predominantly in the nucleus, is packaged into the tegument of virions. At the mid-stage of virus replication in epithelial TW01-EBV cells, a small pool of BALF2 colocalizes with tegument protein BBLF1, BGLF4 protein kinase, and the cis-Golgi marker GM130 at the perinuclear viral assembly compartment (AC). A possible nuclear localization signal (NLS) between amino acids 1100 and 1128 (C29), which contains positive charged amino acid 1113RRKRR1117, is able to promote yellow fluorescent protein (YFP)-LacZ into the nucleus. In addition, BALF2 interacts with the nucleocapsid-associated protein BVRF1, suggesting that BALF2 may be transported into the cytoplasm with nucleocapsids in a nuclear egress complex (NEC)-dependent manner. A group of proteins involved in intracellular transport were identified to interact with BALF2 in a proteomic analysis. Among them, the small GTPase Rab1A functioning in bi-directional trafficking at the ER-Golgi interface is also a tegument component. In reactivated TW01-EBV cells, BALF2 colocalizes with Rab1A in the cytoplasmic AC. Expression of dominant-negative GFP-Rab1A(N124I) diminished the accumulation of BALF2 in the AC, coupling with attenuation of gp350/220 glycosylation. Virion release was significantly downregulated by expressing dominant-negative GFP-Rab1A(N124I). Overall, the subcellular distribution of BALF2 is regulated through its complex interaction with various proteins. Rab1 activity is required for proper gp350/220 glycosylation and the maturation of EBV. IMPORTANCE Upon EBV lytic reactivation, the virus-encoded DNA replication machinery functions in the nucleus, while the newly synthesized DNA is encapsidated and transported to the cytoplasm for final virus assembly. The single-stranded DNA binding protein BALF2 executing functions within the nucleus was also identified in the tegument layer of mature virions. Here, we studied the functional domain of BALF2 that contributes to the nuclear targeting and used a proteomic approach to identify novel BALF2-interacting cellular proteins that may contribute to virion morphogenesis. The GTPase Rab1, a master regulator of anterograde and retrograde endoplasmic reticulum (ER)-Golgi trafficking, colocalizes with BALF2 in the juxtanuclear concave region at the midstage of EBV reactivation. Rab1 activity is required for BALF2 targeting to the cytoplasmic assembly compartment (AC) and for gp350/220 targeting to cis-Golgi for proper glycosylation and virion release. Our study hints that EBV hijacks the bi-directional ER-Golgi trafficking machinery to complete virus assembly.

Active-fluidics versus gravity-fluidics in lens extraction: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To investigate differences in outcomes between active-fluidics and gravity-fluidics phacoemulsification systems. METHODS: We searched PubMed, Embase, and Cochrane Library databases for randomized controlled trials (RCTs) published no later than December 1, 2021. The Cochrane Collaboration risk of bias tool was used for quality assessment. We presented the outcomes as standardized mean differences (SMDs) with 95% confidence intervals (CI). Sensitivity analysis was performed by removing studies that included ≥2 types of phacoemulsification tips. RESULTS: We analyzed six RCTs that totally enrolled 884 patients. Patients undergoing lens extraction with active-fluidics systems exhibited lower cumulative dissipated energy (CDE), total aspiration time (TAT), and estimated fluid usage (EFU) compared with patients who did not (SMD [95% CI]: CDE, - 0.818 [ - 1.054 to - 0.582]; TAT, - 0.664 [ - 0.850 to - 0.479]; EFU, - 0.655 [ - 0.932 to - 0.378]). A sensitivity analysis revealed similar results for CDE, TAT, and EFU. For endothelial cell density (ECD) 1 week after surgery, ECD 1 month after surgery, and central corneal thickness (CCT) 1 week after surgery, outcomes of both systems were comparable (ECD at 1 week, 0.074 [ - 0.177 to 0.325]; ECD at 1 month, 0.069 [ - 0.167 to 0.305]; CCT 1 week after surgery, 0.077 [ - 0.173 to 0.328]). No severe adverse events in patients treated with either system were reported in the studies. CONCLUSION: Active-fluidics systems are superior to gravity-fluidics systems with respect to CDE, TAT, and EFU; no differences in postoperative ECD and CCT were observed. Future studies are required to determine the reasons for heterogeneity and to detect rare adverse events.

Pickering emulsion-enhanced Vibrio fischeri assay for ecotoxicity assessment of highly hydrophobic polycyclic aromatic hydrocarbons.

Accurate ecotoxicity assessment of contaminated soil is critical to public health, and the luminescent bacteria (Vibrio fischeri) method is the most commonly used. Hydrophobic compounds such as polycyclic aromatic hydrocarbons (PAHs) in soil cannot be in contact with luminescent bacteria due to their low water solubility so that the luminescence inhibitory effect cannot be observed. The underestimated biological toxicity makes the test unreliable and en-dangers public health and safety. The commonly adopted improved method of adding cosolvents has limited effect, it was only effective for low-hydrophobicity chemicals and could not be used for ecotoxicity evaluation of high-hydrophobicity chemicals. Therefore, we constructed Pickering emulsions using luminescent bacteria modified with n-dodecanol in which PAHs were dissolved in the oil phase, n-tetradecane. Then the luminescent bacteria could tightly adhere to the oil-water interface and contact PAHs. As a result, their bioluminescence was suppressed to varying degrees depending on the chemical species and concentrations. With no solubility limitation, highly hydrophobic PAHs could even completely inhibit bacterial bioluminescence, hence the toxicity information was accurately displayed and the median effect concentration (EC50) values could be calculated. This Pickering emulsion-based method was successfully applied for the accurate ecotoxicity evaluation of highly hydrophobic PAHs and soil samples contaminated with them, which all previous methods could not achieve. This method overcomes the problem of ecotoxicity evaluation of hydrophobic compounds, and has great potential for practical application, whether it is pure chemicals or various real samples from the ecological environment.

Self-assembled hyaluronic acid-coated nanocomplexes for targeted delivery of curcumin alleviate acute kidney injury.

Acute kidney injury (AKI) is a pathological process with high morbidity, and drug resistance is easy to occur due to untargeted drug therapy. Curcumin can repair acute kidney injury. The expression of the CD44 receptor in renal tubular epithelial cells is abnormally elevated during AKI, and hyaluronic acid (HA) has the ability to bind specifically to the CD44 receptor. In this study, we developed a hyaluronic acid-coated liposome (HALP) nanocomplexes that targeted renal epithelial cells and its effect of relieving AKI was investigated. HALP was formed by self-assembly through the electrostatic interaction of curcumin-loaded cationic liposomes (LP) with hyaluronic acid and responds to the release of curcumin in the acidic microenvironment of lesions to treat AKI. HALP had good stability and biocompatibility. The in vitro results showed that compared to LP, HALP exhibited higher antioxidant, anti-inflammatory, and anti-apoptotic capacities. The AKI model suggested that HALP could not only target and accumulate in the injured kidney but also had an excellent ability to reduce the inflammatory response, which decreased tubular necrosis and restored kidney function.

Survival outcomes of patients with head and neck squamous cell cancer with hepatitis B virus infection: An analysis from an endemic tertiary center.

BACKGROUND: Hepatitis B virus (HBV) affects the occurrence and survival outcome of various malignant disorders. The study aimed to evaluate the survival outcome of head and neck squamous cell cancer (HNSCC) patients with or without HBV infection. METHODS: This study included patients with HNSCC who visited Taichung Veterans General Hospital from 2007 to 2015. HBV infection was defined by hepatitis B surface antigen (HBsAg) seropositivity. By propensity score matching, we compared survival outcomes, including progression-free survival (PFS) and overall survival (OS), among patients with or without HBV infection. RESULTS: The prevalence of HBV infection in our cohort was 12.3%. Among the 1,015 patients included in the matched analysis, a higher risk of baseline liver cirrhosis (11.3% vs. 3.4%, p < 0.001) and initial hepatic dysfunction (10.8% vs. 5.4%, p = 0.005) rates were observed than those without HBV infection at baseline. The 5-year OS was 43.1% and 53.2% (p < 0.001) and the 5-year PFS was 37.4% and 42.3% (p = 0.007) in patients with and without HBV infection, respectively. The incidence of subsequent hepatic dysfunction showed no difference between patients with and without HBV infection (29.6% vs. 26.8%, p = 0.439). CONCLUSIONS: Patients with HNSCC and HBV infection were younger and had a higher risk of cirrhosis compared to those without HBV infection. Moreover, HBV infection significantly influenced the OS and PFS outcomes but not subsequent hepatic dysfunction in patients with HNSCC.

Copper nanoclusters on specific-primer PCR fragments with magnetic capture for the label-free fluorescent sensing of the T315I single nucleotide variant in the BCR-ABL1 gene.

In this study, a simple and facile procedure using the all or none formation of double-stranded DNA-templated copper nanoclusters on specific-primer PCR fragments was designed to fluorescently identify the T315I single nucleotide variant on the BCR-ABL1 gene. Chronic myeloid leukaemia (CML), a disease caused by the BCR-ABL1 fusion of tyrosine kinase, is well known for the T315I mutation that causes tyrosine kinase inhibitors (TKIs) to be resisted due to the alternative structure of the drug-binding site. Therefore, it is an important single nucleotide variant for clinical detection. In this study, only specific functional primers and the digestion of the wild genotype from the T315I mutation site with specific restriction enzymes were designed, and the different digested products could then be captured using magnetic beads. The final products would allow for fluorescent sensing via the all or none formation of double-stranded DNA-templated copper nanoclusters for the detection of the T315I mutation. This study has been successfully applied for identifying wild and mutant homozygotes and the mutant/wild heterozygote of the T315I mutation. It is expected that this analytical system can serve as a tool for the clinical diagnosis of T315I mutations and be applied to real samples of CML patients in the future.

The Relationship between Sarcopenia and Injury Events: A Systematic Review and Meta-Analysis of 98,754 Older Adults.

The main purpose of this study was to investigate the relationship between sarcopenia and injury events (falls, fractures, hospitalization, disability, and death). This study systemically searched the literature from Embase, PubMed, MEDLINE, CINAHL, and Cochrane Library and analyzed the collected literature using the random effects model to demonstrate the relationship between sarcopenia and injury events. This study followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and collected a total of 38 prospective studies, and the results showed that, when compared to robust individuals, the risk of injury events for older individuals with sarcopenia was significantly higher for fractures (HR = 9.66, CI: 5.07-18.38), hospital admissions (HR = 11.80, CI: 4.86-28.65), and death (HR = 9.57, CI: 3.17-28.94). In consideration of the negative impact of sarcopenia on the subsequent health of older adults, professional nursing personnel should assess older adults for sarcopenia as early as possible and propose relevant care policies to further reduce negative health impacts.

Comparative anatomical outcomes of high-flow vs. low-flow phacoemulsification cataract surgery: A systematic review and meta-analysis.

Background: Phacoemulsification is an effective and widely performed technique in cataract surgery, but the comparative anatomical outcomes, including endothelial cell loss (ECL), central corneal thickness (CCT), and central macular thickness (CMT), between high-flow and low-flow phacoemulsification cataract surgery remain unclear. Methods: This study followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Random-effects models were applied to measure pooled mean differences (MD) with 95% confidence intervals (CI) of anatomical outcomes between high-flow and low-flow phacoemulsification cataract surgery. We judged overall certainty of evidence (CoE) based on Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Results: We included six randomized controlled trials (RCTs) totaling 477 participants. The meta-analysis showed similar changes associated with these two surgery types in both ECL at postoperative days 2-14 (MD: -1.63%; 95% CI: -3.73 to 0.47%; CoE: very low), days 15-42 (MD: -0.65%; 95% CI -2.96 to 1.65%; CoE: very low) and day 43 to month 18 (MD: -0.35%; 95% CI: -1.48 to 0.78%; CoE: very low), and CCT at postoperative day 1 (MD: -16.37 µm; 95% CI: -56.91 to 24.17 µm; CoE: very low), days 2-14 (MD: -10.92 µm; 95% CI: -30.00 to 8.16 µm; CoE: very low) and days 15-42 (MD: -2.76 µm; 95% CI: -5.75 to 0.24 µm; CoE: low). By contrast, low-flow phacoemulsification showed less increase in CMT at postoperative days 15-42 (MD, -4.58 µm; 95% CI: -6.3 to -2.86 µm; CoE: low). Conclusions: We found similar anatomical outcomes, except in CMT, for both high-flow and low-flow phacoemulsification cataract surgery. Future head-to-head RCTs on visual outcomes should confirm our findings. Systematic review registration: PROSPERO, identifier: CRD42022297036.

Monitoring of the yogurt fermentation process based on a rapid bio-luminescent chiral pattern recognition of amino acids.

The analysis of chiral α-amino acids is of great significance in asymmetric synthesis, nutrition, food science, and microbiology. However, the ability of chiral recognition is difficult to achieve. Due to the demand for expensive equipment and skilled operators, traditional methods such as high-performance liquid chromatography are limited. The previously reported methods based on chemical sensor arrays usually cannot carry out the chiral analysis. Here, we developed a novel biosensor array based on the interaction between a suite of host-based luminescent bacteria and amino acids and used linear discriminant analysis to reflect their luminescence response patterns. This biosensor array could effectively discriminate chiral amino acids, including 19 L-amino acids, their corresponding D-enantiomers, and the achiral glycine. In addition, the determination of enantiomeric purity and quantitative ability has been proved. The successful identification of a complex system containing multiple chiral amino acids further demonstrates the superiority of the bioluminescent sensor array. Moreover, this sensor array could efficiently monitor the dynamic composition of free amino acids in the process of milk fermentation. Finally, the bioluminescence response mechanism of the luminescent bacteria for the recognition of chirality was clarified. This approach possessed the advantages of facile construction, high throughput, easy operation, high accuracy and fast response.

Comparison of Sodium-Glucose Cotransporter 2 Inhibitors vs Glucagonlike Peptide-1 Receptor Agonists and Incidence of Dry Eye Disease in Patients With Type 2 Diabetes in Taiwan.

Importance: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been found to improve low-grade systemic and tissue inflammation; however, the association between SGLT2 inhibitor use and the incidence of dry eye disease (DED) has not been explored. Objective: To investigate the association between SGLT2 inhibitor use and dry eye disease in patients with type 2 diabetes (T2D). Design, Setting, and Participants: A retrospective cohort analysis of the largest multi-institutional electronic medical records database in Taiwan was conducted to identify patients with T2D newly receiving SGLT2 inhibitors or glucagonlike peptide-1 receptor agonists (GLP-1 RAs) from 2016 to 2018. Data analysis was performed from March 1 to May 31, 2022. Propensity scores with inverse probability of treatment weighting were generated to enable homogeneous comparisons between the 2 groups. Exposures: Treatment with SGLT2 inhibitors or GLP-1 RAs. Main Outcomes and Measures: Incident dry eye disease, which was defined by clinical diagnoses, plus the related drug prescription. Cox proportional hazards regression models were used to estimate hazard ratios with 95% CIs for the risk of DED. Results: A total of 10 038 and 1077 T2D patients newly receiving SGLT2 inhibitors (mean [SD] age, 59.5 [12.1] years; 5689 [56.7%] men) or GLP-1 RAs (mean [SD] age, 58.5 [41.2] years; 587 [54.5%] men), respectively, were included in the analysis. The incidence of DED was lower in patients newly receiving SGLT2 inhibitors (9.0 events per 1000 person-years) compared with those receiving GLP-1 RAs (11.5 events per 1000 person-years), yielding a hazard ratio of 0.78 (95% CI, 0.68-0.89). Subgroup analyses indicated that the lowered DED risks associated with SGLT2 inhibitors in patients with T2D were similar across different age, sex, blood glucose level, and kidney function groups. Results from the sensitivity analyses (including the propensity score-matching approach, on-treatment analyses, and different follow-up periods of 1, 2, and 3 years) were similar to the main analyses. Conclusions and Relevance: The findings of this study suggest that patients with T2D newly receiving SGLT2 inhibitors may have a lower risk for DED compared with those receiving GLP-1 RAs. Prospective studies are needed to analyze these results.

Risk of dialysis in patients receiving intravitreal anti-vascular endothelial growth factor treatment: a population-based cohort study.

We utilized the Longitudinal Health Insurance Database which was stemmed from the Taiwan's National Health Insurance Research Database to conduct a retrospective cohort study investigating the risk of becoming dialysis dependent after receiving intravitreal anti-vascular endothelial growth factor (VEGF) agents for retinal diseases. Patients newly receiving intravitreal ranibizumab or aflibercept from 2000 to 2017 for age-related macular degeneration, polypoidal choroidal vasculopathy, diabetic macular edema, retinal vein occlusions, or myopic choroid neovascularization were included as the study group, and patients with same retinal diseases but did not receive intravitreal anti-VEGFs served as controls extracted by age- and sex-matched (1:4) and further propensity score matching (PSM). Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the risk of dialysis. A cohort of 2447 anti-VEGF users and 2447 controls by PSM were evaluated. Higher dialysis risks were observed among patients newly receiving anti-VEGF agents compared to controls (adjusted HR: 1.849; 95% CI: 1.378-2.482) in the PSM cohort. For subgroup analysis, patients newly receiving anti-VEGF treatment for diabetic macular edema had significant risk (adjusted HR: 1.834; 95% CI: 1.448-2.324) of becoming dialysis-dependent, while patients in other subgroups demonstrated similar risks as the controls. In conclusion, intravitreal anti-VEGF agents might increase the risk of becoming dialysis-dependent, especially in patients who are treated for diabetic macular edema.

Clinical Features and Immunophenotypes of Double-Hit Diffuse Large B-Cell Lymphoma.

Double-hit (DH) genetics induces a reduction in the complete remission (CR) and, consequently, in poor overall survival (OS) in diffuse large B-cell lymphoma (DLBCL) patients. Unfortunately, DH identification is time-consuming. Here, we retrospectively reviewed 92 newly diagnosed DLBCL patients, stratified them into the DH (n = 14) and non-DH groups (n = 78), and compared their clinical features and outcomes. The results revealed that the DH group had a higher percentage of bulky disease than the non-DH group (64.3% vs. 28.2%; p = 0.013). More patients in the DH group tested positive for double expresser (DE) (50.0% vs. 21.8%; p = 0.044). The three-year OS rates of patients with and without DH were 33.3% and 52.2%, respectively (p = 0.016). Importantly, advance stage and multiple comorbidities were correlated with a high mortality rate in multivariate analysis. Furthermore, by combining DE and the bulky disease, a specificity of 89.7% for DH prediction was achieved. In summary, DH genetics, not DE immunopositivity, could be a factor for an inferior OS in DLBCL. A combination of bulky disease and a positive DE immunophenotype could facilitate DH genetics prediction in newly diagnosed DLBCL patients.
