RESUMO
Geosystem services (GSs) and ecosystem services (ESs) are interconnected, both representing nature's contributions to people. Whether GSs are a subset of ESs depends on the definition of ESs. The answer would be "not necessarily" (i.e., some GSs are, while other GSs are not), if ESs are the benefits humans derive from ecological functions, processes, or characteristics. The boundary proposed by Chen et al. (2023) to differentiate ESs from other ecosystem-related benefits adopted this definition, and suggested that ESs are renewable and affected by biotic elements to occur. Gray et al. (2024) criticized this boundary for separating out bits of nature and ignoring the contributions of GSs and abiotic elements to ESs and human wellbeing. In fact, highlighting that ESs are affected by biotic elements to occur does not deny that ESs' occurrence is also affected by abiotic elements. However, ESs' dependence on abiotic elements cannot be a criterion to differentiate ESs from other benefits because abiotic elements are integral to geosystems, ecosystems, and many other natural and artificial systems, as well as to these systems' services. Conversely, while geosystems might persist without biotic elements, ecosystems cannot. Chen et al. (2023) only excluded those (not the whole) abiotic benefits, such as wind energy, that may occur independently of biotic elements, while allowing for integrating certain GSs into ESs. For example, geological structures can offer flood protection and water storage as GSs, which can also be classified as ESs when their qualities or quantities are affected by biotic elements. Differentiation between GSs and ESs should not be misinterpreted as splitting their interconnections or undervaluing or dividing nature. Instead, such differentiation and classification of nature's benefits serve to facilitate communication, management, education, research, and policy-making associated with nature's benefits, while also highlighting the richness and diversity of nature's benefits.

BACKGROUND: Cervical cancer remains one of the most prevalent cancers worldwide. Accumulating evidence suggests that specificity protein 1 (Sp1) plays a pivotal role in tumour progression. The underlying role and mechanism of Sp1 in tumour progression remain unclear. METHODS: The protein level of Sp1 in tumour tissues was determined by immunohistochemistry. The effect of Sp1 expression on the biological characteristics of cervical cancer cells was assessed by colony, wound healing, transwell formation, EdU, and TUNEL assays. Finally, the underlying mechanisms and effects of Sp1 on the mitochondrial network and metabolism of cervical cancer were analysed both in vitro and in vivo. RESULTS: Sp1 expression was upregulated in cervical cancer. Sp1 knockdown suppressed cell proliferation both in vitro and in vivo, while overexpression of Sp1 had the opposite effects. Mechanistically, Sp1 facilitated mitochondrial remodelling by regulating mitofusin 1/2 (Mfn1/2), OPA1 mitochondrial dynamin-like GTPase (Opa1), and dynamin 1-like (Drp1). Additionally, the Sp1-mediated reprogramming of glucose metabolism played a critical role in the progression of cervical cancer cells. CONCLUSIONS: Our study demonstrates that Sp1 plays a vital role in cervical tumorigenesis by regulating the mitochondrial network and reprogramming glucose metabolism. Targeting Sp1 could be an effective strategy for the treatment of cervical cancer.

OBJECTIVES: This study aimed to investigate corneal epithelial and topographic changes caused by two commercial myopia orthokeratology (ortho-k) designs. METHODS: Twenty-six subjects fitted with vision shape treatment (VST) lenses and 30 subjects fitted with corneal reshaping therapy (CRT) lenses were reviewed 1 day, 1 week, and 1 month after lens initiation. A spectral-domain optical coherence tomography system was used to create epithelial maps that were in turn used to determine the average epithelial thickness of each zone and the diameter of treatment zone. By measuring the topographic tangential differential map, the treatment zone diameter and the power and width of the high convex zone (HCZ) were obtained. All epithelial thicknesses and topographic corneal variations recorded were analyzed. RESULTS: At the central zone, the epithelial thickness changes (â³ET) decreased significantly after 1 day of ortho-k in two groups. At 2- to 9-mm peripheral zone, ortho-k increased â³ET until 1 week in the VST group, whereas it kept increasing in the CRT group after 1 week. At 1 month, the central â³ET is -9.51±2.38 mm in the VST group, which was comparable to -8.72±3.43 mm in the CRT group. The nasal HCZ power and the â³ET of nasal and inferior nasal were significantly larger in the CRT group. A positive correlation was found between the HCZ power and â³ET generated by VST-type lenses inferiorly and temporally. For the CRT group, a positive correlation was found between inferior HCZ power and â³ET. CONCLUSIONS: At the early stage of ortho-k, epithelial thickness and topography change quickly and simultaneously. Epithelial changes were in line with corneal topography reshaping. Epithelial and optical remodelling were affected by different lens types.

The epithelial-mesenchymal transition (EMT) is an important process during metastasis in various tumors, including colorectal cancer (CRC). Thus, the study of its characteristics and related genes is of great significance for CRC treatment. In this study, 26 EMT-related gene sets were used to score each sample from The Cancer Genome Atlas program (TCGA) colon adenocarcinoma (COAD) database. Based on the 26 EMT enrichment scores for each sample, we performed unsupervised cluster analysis and classified the TCGA-COAD samples into three EMT clusters. Then, weighted gene co-expression network analysis (WGCNA) was used to investigate the gene modules that were significantly associated with these three EMT clusters. Two gene modules that were strongly positively correlated with the EMT cluster 2 (worst prognosis) were subjected to Cox regression and least absolute shrinkage and selection operator (LASSO) regression analysis. Then, a prognosis-related risk model composed of three hub genes GPRC5B, LSAMP, and PDGFRA was established. The TCGA rectal adenocarcinoma (READ) dataset and a CRC dataset from the Gene Expression Omnibus (GEO) were used as the validation sets. A novel nomogram that incorporated the risk model and clinicopathological features was developed to predict the clinical outcomes of the COAD patients. The risk model served as an independent prognostic factor. It showed good predictive power for overall survival (OS), immunotherapy efficacy, and drug sensitivity in the COAD patients. Our study provides a comprehensive evaluation of the clinical relevance of this three-gene risk model for COAD patients and a deeper understanding of the role of EMT-related genes in COAD.

Ecosystem Services (ESs) are either material or non-material benefits humans receive from ecosystems. Definitions, classifications, and typologies of ESs can vary to address different research and policy purposes. However, a boundary that distinguishes ESs from other ecosystem-related benefits (e.g., industrial products that consume raw materials, fossil fuels that used to be a part of ecosystems) is needed to avoid the risk of using ESs as an all-encompassing metaphor that captures any benefit. The boundary also maintains a common ground for communication and comparison of ESs across studies. To guide future development and application of the ES concepts, we suggest five criteria. ESs are (1) primary contributions of ecosystems, (2) flows assessed during a period or per time unit (not stock existing at a time point), (3) renewable (having the potential to be reproduced with a conceivable timeframe relevant to human use), (4) affected by biotic parts of ecosystems to occur. ESs include both biotic and some abiotic flows (e.g., water provisioning) but exclude abiotic flows (e.g., wind and solar energy) whose occurrence is unaffected by ecosystem functions, processes, or characteristics; and (5) inclusive to the benefits humans actually and potentially receive from ecosystems. These criteria link ESs with conservation of life-supporting and culturally important ecosystems, recognize use, option, and non-use values of ESs, and highlight ESs' sustainability.

Mortalin is involved in the malignant phenotype of many cancers. However, the specific molecular mechanisms involving Mortalin in lung adenocarcinoma remain unclear. In this study, we showed that both Mortalin mRNA and protein are overexpressed in lung adenocarcinoma. In addition, Mortalin overexpression was positively correlated with poor overall survival. In vitro experiments showed that Mortalin silencing inhibited the proliferation, colony formation and migration abilities of A549 and H1299 cells. Mortalin promotes EMT progression, angiogenesis and tumor progression by activating the Wnt/ß-catenin signaling pathway. In vivo experiments further confirmed that Mortalin promoted malignant progression of lung adenocarcinoma. Taken together, our data suggest that Mortalin represents an attractive prognostic marker and therapeutic target in lung adenocarcinoma patients.

PD-L1 is closely related to the immune escape process of tumour cells, and targeted PD-L1 clinical immunotherapy has been implemented. However, whether PD-L1 is involved in TAM/M2 polarization in the TME of NSCLC and its specific mechanism remain unclear. In order to clarify the specific role of PD-L1 in NSCLC and to seek new treatments for NSCLC, we designed a series of experimental studies. After constructing the co-culture system and conditioned medium system, the proliferation, apoptosis, metastasis, angiogenesis, EMT process and stemness of NSCLC were detected by MTT, flow cytometry, Transwell, endothelial cell tube formation and western blot assays. The results showed that αPD-L1 reversed TAM/M2 polarization by suppressing STAT3 phosphorylation in TAM/M2, therapy inhibiting NSCLC cell migration, angiogenesis, EMT process and stemness. However, αPD-L1 had no effect on the proliferation and apoptosis abilities of NSCLC cells. In vivo experiments showed that αPD-L1 inhibited lung metastasis of NSCLC and reversed TAM/M2 polarization in TME. The study investigates the mechanism by which PD-L1 regulates TAMs polarization in TME and promotes malignant progression of NSCLC, providing a new theoretical basis for PD-L1 targeted therapy of NSCLC.

CircBRWD3 is a newly discovered circRNA, and its potential function has not been probed. Here, we aimed to molecularly dissect the role of circBRWD3 in the tumorigenesis and progression of breast cancer (BC). qRT-PCR analysis revealed that circBRWD3 expression was dramatically upregulated in BC tissues, a feature that was positively correlated with the poor prognosis of patients with BC. CircBRWD3 knockdown repressed cell proliferation and metastasis, while promoting cell apoptosis in vitro. Consistently, an in vivo circBRWD3 deficiency model exhibited suppressed tumor metastasis and oncogenesis. On the other hand, circBRWD3 overexpression promoted cancer cell activity and tumorigenesis. Further, mechanistic studies elucidated that circBRWD3 sponged both miR-142-3p and miR-142-5p to modulate RAC1 expression, which subsequently activated the RAC1/PAK1 signaling to facilitate the tumorigenesis and progression of BC. Moreover, we discovered that EIF4A3 facilitated circBRWD3 expression by targeting the upstream of BRWD3 pre-mRNA. In conclusion, our study reveals that circBRWD3 facilitates BC tumorigenesis by regulating the circBRWD3/miR-142-3p_miR-142-5p /RAC1/PAK1 axis. In addition, circBRWD3 expression is positively regulated by an RNA-binding protein, EIFA3. Our results provide valuable scientific data for early diagnosis and therapy for breast cancer patients.

INTRODUCTION: The macular morphologic and microvascular changes in children with pseudophakia after pediatric cataract surgery remain unknown. The aim of this study was to analyze macular morphologic and microvascular remodeling in children with pseudophakia after pediatric cataract surgery using optical coherence tomography angiography (OCTA). METHODS: Consecutive cases between December 1, 2018, and November 31, 2020 were recruited. Sixty-one participants (31 pseudophakic children and 30 healthy controls) met the inclusion criteria and were included for final analysis. OCTA was used to measure macular vascular density, the foveal avascular zone (FAZ), and macular thickness. The parameters were compared between pseudophakic and healthy eyes using binary logistic regression, with adjustment for the effect of refractive error, age, and axial length. RESULTS: Compared with normal eyes, a significantly reduced area of the FAZ (p = 0.042), increased superficial foveal vascular density (p = 0.033), and increased inner and outer foveal thickness (p = 0.034 and 0.029, respectively) were noted in pseudophakic eyes. The deep parafoveal vascular density was generally lower in eyes with cataracts (p ≤ 0.044). The inner foveal thickness was positively correlated with the superficial foveal vascular density (r = 0.889, p < 0.001) and negatively correlated with the area of the FAZ (r = -0.903, p < 0.001). The outer foveal thickness was positively correlated with the deep foveal vascular density (r = 0.399, p = 0.002). CONCLUSIONS: Morphological and microvascular remodeling in children with previous pediatric cataract indicates foveal underdevelopment. The underlying mechanism requires further investigation.

BACKGROUND: Feruloyl oligosaccharides (FOs), the ferulic acid ester of oligosaccharides, may possess the physiological functions of both ferulic acid and oligosaccharides, including antioxidative activity and gut microbiota modulation capacity. The present study aimed to investigate whether FOs could regulate the intestinal antioxidative capacity of rats by modulating the MAPKs/Nrf2 signaling pathway and gut microbiota. Thirty Wistar rats were randomly divided into five groups. Rats received a standard diet and were gavaged once daily with 0.85% normal saline, 100 mg kg-1 body weight vitamin C or FOs solution at doses of 20, 40 and 80 mg kg-1 body weight for 21 days. RESULTS: FOs strengthened the antioxidative capacity of the jejunum, as indicated by increased in contents of catalase, superoxide dismutase and glutathione peroxidase, as well as glutathione. Moreover, FOs administration upregulated the mRNA expression level of antioxidant-related genes (glutamate-cysteine ligase catalytic subunit, glutamate-cysteine ligase modifier subunit and heme oxygenase-1) in the jejunum. Increases in phosphorylation levels of Nrf2, p38 and JNK were also observed. Administration with 40 mg kg-1 FOs altered the structure and composition of the cecal microbiota, which was indicated by the increased the relative abundances of Actinobacteria, Proteobacteria and Acidobacteriota, and the decreased the relative abundances of Firmicutes, Lachnospiraceae_NK4A136_group and Blautia. Furthermore, Spearman correlation analysis revealed that the altered cecal microbiota closely correlated with jejunal antioxidative capacity of rats. CONCLUSION: FOs could be used as an antioxidant for gut heath improvement through modulating the p38/JNK-Nrf2 signaling pathway and gut microbiota. © 2022 Society of Chemical Industry.

Mortalin is a member of the heat shock protein 70 (HSP70) family that promotes the development of many cancers. It is reportedly a tumor promoter, but the mechanism of Mortalin in breast cancer is unclear. We designed a series of experiments to explore the correlation between Mortalin and the malignancy of breast cancer, and to assess the potential of Mortalin as a novel therapeutic target in breast cancer. The expression level of Mortalin in breast cancer tissues was detected. Then, we did a series of functional experiment. The findings indicated that Mortalin facilitates the proliferation, metastasis, and endothelial-to-mesenchymal transition (EMT) process of breast cancer. In our research, Mortalin is regulated EMT process and malignant progression of breast cancer through Wnt/ß-Catenin signaling pathway. The findings imply that Mortalin significantly promotes the progression of breast cancer malignancy and reduces patient survival, suggesting that Mortalin as a biomarker and prognostic factor in breast cancer.

BACKGROUND: This study profiled the somatic genes mutations and the copy number variations (CNVs) in cerebrospinal fluid (CSF)-circulating tumor DNA (ctDNA) from patients with neoplastic meningitis (NM). METHODS: A total of 62 CSF ctDNA samples were collected from 58 NM patients for the next generation sequencing. The data were bioinformatically analyzed by (Database for Annotation, Visualization and Integrated Discovery) DAVID software. RESULTS: The most common mutated gene was TP53 (54/62; 87.10%), followed by EGFR (44/62; 70.97%), PTEN (39/62; 62.90%), CDKN2A (32/62; 51.61%), APC (27/62: 43.55%), TET2 (27/62; 43.55%), GNAQ (18/62; 29.03%), NOTCH1 (17/62; 27.42%), VHL (17/62; 27.42%), FLT3 (16/62; 25.81%), PTCH1 (15/62; 24.19%), BRCA2 (13/62; 20.97%), KDR (10/62; 16.13%), KIT (9/62; 14.52%), MLH1 (9/62; 14.52%), ATM (8/62; 12.90%), CBL (8/62; 12.90%), and DNMT3A (7/62; 11.29%). The mutated genes were enriched in the PI3K-Akt signaling pathway by the KEGG pathway analysis. Furthermore, the CNVs of these genes were also identified in these 62 samples. The mutated genes in CSF samples receiving intrathecal chemotherapy and systemic therapy were enriched in the ERK1/2 signaling pathway. CONCLUSIONS: This study identified genes mutations in all CSF ctDNA samples, indicating that these mutated genes may be acted as a kind of biomarker for diagnosis of NM, and these mutated genes may affect meningeal metastasis through PI3K-Akt signaling pathway.

BACKGROUND: ED overutilization is a leading cause of increased healthcare costs and a key target for healthcare reform. ED utilization patterns following common operative procedures are unknown. METHODS: Using the SPARCS New York (NY) statewide longitudinal administrative database, a longitudinal analysis on 746,633 patients who underwent cholecystectomy (n = 355,368), appendectomy (n = 142,797) or inguinal hernia repair (n = 248,468) from 2005 to 2014 was performed. ED revisits were identified via unique patient identifiers which allow for patient tracking across hospitals in NY State. RESULTS: In total, 59,255 (7.9%) patients presented to the ED within 30-days of their operation of which 21,638 (36.5%) were admitted. The aggregated rate of ED utilization and admission from the ED were as follows: cholecystectomy (9.5%, 40%), appendectomy (9.1%, 33.1%), and inguinal hernia repair (5.1%, 26.2%), respectively. A longitudinal analysis demonstrated a relative slowing of the rate of increase in hospital readmissions for cholecystectomy and inguinal hernia repair but no change in the number of ED revisits for inguinal hernia repair. CONCLUSIONS: Nearly 1 in 10 patients undergoing cholecystectomy and appendectomy, and 1 in 20 patients undergoing inguinal hernia repair will present to the ED following surgery. The majority of ED visits do not result in admission, calling their necessity into question. These data suggest possible overutilization of the ED following common operations and support the consideration of ED utilization as a quality indicator.

BACKGROUND: Impaired gut microbiota leads to pathogenic bacteria infection, pro-inflammatory response and post-weaning diarrhea. Enterotoxigenic Escherichia coli (ETEC) K88 is a major cause of post-weaning diarrhea in weaned piglets. Fermented soybean meal (FSBM) could relieve diarrhea, alleviate inflammatory response, and modulate gut microbiota of weaned piglets. We used ETEC K88-challenged weaned piglet model to investigate the effects of FSBM on the growth performance, inflammatory response and cecal microbiota. Twenty-four crossbred piglets (6.8 ± 0.5 kg; 21 ± 2 days of age) were allotted into 2 treatment fed the diets with or without FSBM (6% at the expense of soybean meal). Six weaned piglets in each diet treatment were challenged by ETEC K88 (1 × 109 CFU/piglets) on day 15. The experimental period lasted for 20 days. RESULTS: The ETEC K88 challenge decreased (p < 0.05) fecal consistency and plasma interleukin-10 (IL-10) concentration, while increased (p < 0.05) average daily feed intake (ADFI) and plasma tumor necrosis factor-α (TNF-α), interleukin-1ß (IL-1ß) and interleukin 6 (IL-6) concentrations. After ETEC K88 challenge, dietary FSBM replacement increased (p < 0.05) final body weight (BW), average daily gain (ADG), ADFI, and fecal consistency, but decreased feed conversion ratio (FCR). The plasma IL-10 concentration of weaned piglets fed FSBM was higher (p < 0.05), while IL-1ß, IL-6 and TNF-α concentrations were lower (p < 0.05). Dietary FSBM replacement attenuated the increase of plasma TNF-α concentration and the decrease of ADG induced by ETEC K88 challenge (p < 0.05). High-throughput sequencing of 16S rRNA gene V4 region of cecal microbiota revealed that ETEC K88 challenge increased (p < 0.05) Campylobacter relative abundance on genus level. Dietary FSBM replacement resulted in higher (p < 0.05) relative abundances of Bacteroidetes and Prevotellaceae_NK3B31_group, and lower (p < 0.05) relative abundances of Proteobacteria and Actinobacillus. Furthermore, dietary FSBM replacement relieved the increase of Escherichia-Shigella relative abundance in weaned piglets challenged by ETEC K88 (p < 0.05). CONCLUSIONS: Dietary FSBM replacement improved growth performance and alleviated the diarrhea of weaned piglets challenged with ETEC K88, which could be due to modulation of cecal microbiota composition and down-regulation of inflammatory cytokines production.

BACKGROUND Despite noteworthy advancements in the multidisciplinary treatment of colorectal cancer (CRC) and deeper understanding in the molecular mechanisms of CRC, many of CRC patients with histologically identical tumors present different treatment response and prognosis. Thus, more evidence on novel predictive and prognostic biomarkers for CRC remains urgently needed. This study aims to identify potential prognostic biomarkers for CRC with integrative gene expression profiling analysis. MATERIAL AND METHODS Differential expression analysis of paired CRC and adjacent normal tissue samples in 6 microarray datasets was independently performed, and the 6 datasets were integrated by the robust rank aggregation method to detect consistent differentially expressed genes (DEGs). Aberrant expression patterns of these genes were further validated in RNA sequencing data. Then, gene set enrichment analysis (GSEA) was performed to investigate significantly dysregulated biological functions in CRC. Finally, univariate, LASSO and multivariate Cox regression models were built to identify key prognostic genes in CRC patients. RESULTS A total of 990 DEGs (495 downregulated and 495 upregulated genes) were acquired after integratedly analyzing the 6 microarray datasets, and 4131 DEGs (2050 downregulated and 2081 upregulated genes) were obtained from the RNA sequencing dataset. Subsequently, these DEGs were intersected and 885 consistent DEGs were finally identified, including 458 downregulated and 427 upregulated genes. Two risky prognostic genes (TIMP1 and LZTS3) and 5 protective prognostic genes (AXIN2, CXCL1, ITLN1, CPT2 and CLDN23) were identified, which were significantly associated with the prognosis of CRC. CONCLUSIONS The 7 genes that we identified would provide more evidence for further applying novel diagnostic and prognostic biomarkers in clinical practice to facilitate personalized treatment of CRC.

WHAT IS KNOWN AND OBJECTIVE: An increasing macrolide resistance leads to complex clinical treatment schemes in mycoplasma pneumonia in children. Chinese herbal injection (CHI) is widely used to treat it and may provide a new treatment regimen. This study was conducted to systematically evaluate the efficacy of CHIs combined with azithromycin for treating mycoplasma pneumonia in children by Bayesian network meta-analysis. METHODS: Randomized controlled trials (RCTs) of CHIs combined with azithromycin for mycoplasma pneumonia in children were searched in electronic databases and related references from initiation to 30 October 2018. Two researchers conducted data extraction and risk of bias assessment. WinBUGS software and STATA software were adopted to analyse the data. RESULTS: A total of 167 RCTs were included with 5 CHIs involving 16 144 patients. All CHIs combined with azithromycin had superior effects than azithromycin only among overall outcomes. Yanhuning injection combined with azithromycin ranked highest in four different outcomes and second in two based on surface under the cumulative ranking probabilities (SUCRA). Meanwhile, the results of MD and 95% CIs of concerned outcomes indicated that only Yanhuning injection combined with azithromycin had better response than other CHIs combined with azithromycin. Moreover, cluster analysis results revealed Reduning injection combined with azithromycin was associated with a positive effect on the three group outcomes. Similarly, it was found to be the top three ranking in all outcomes based on SUCRA. WHAT IS NEW AND CONCLUSION: Yanhuning injection combined with azithromycin and Reduning injection combined with azithromycin were found to be preferable treatments based on the data of this study.

INTRODUCTION: Common bile duct (CBD) injury is a serious and dreaded complication of cholecystectomy. A paucity of data assessing long-term outcomes exists. This study aimed to determine long-term mortality and liver transplantation rates following CBD injury requiring operative intervention. METHODS: Patients were identified via the New York State (NYS) Planning and Research Cooperative System longitudinal administrative database which captures patient-level data from every inpatient and outpatient hospital discharge in NYS. In total, 125 patients with CBD injuries were identified following 156,958 laparoscopic cholecystectomies for cholelithiasis performed in NYS from 2005 to 2010. Patients were then tracked by unique identifier to obtain rate of liver transplantation. Follow-up ranged from 4 to 9 years from surgery. RESULTS: There were 125 patients with CBD injuries detected. No mortalities occurred within 30 days. All-cause mortality was 20.8 % (n = 26) with mean time to death 1.64 ± 1.08 years. One patient who underwent hepaticoenterostomy required a liver transplant 4.3 years after surgery. Significant factors predictive of all-cause mortality included: age >61, Medicare insurance, male gender, White race, diabetes, hypertension and pulmonary complications following surgery. Overall 30-day morbidity, timing to and type of operative intervention did not influence mortality. CONCLUSION: Considerable long-term mortality, 20.8 %, is associated with common bile duct injury requiring operative intervention. This was an increase of 8.8 % above the cohort's expected age-adjusted rate of death. The mortality rate is appreciably higher than quoted previously. No difference was demonstrated by type of repair required. Liver transplant rate was 0.8 %. These data have significant implications for patient and family counseling both prior to cholecystectomy and following CBD injury.

BACKGROUND: Early reports of higher complication rates, specifically bile duct injuries, raised concerns over the safety of laparoscopy over open cholecystectomy. This study aims to ascertain the rate, management, and perioperative outcomes of bile duct injury in an era beyond the laparoscopic learning curve. METHODS: The New York State (NYS) Planning and Research Cooperative System longitudinal administrative database was used to identify patients. From 2005 to 2010, 156,315 patients were identified who had undergone laparoscopic cholecystectomy for symptomatic cholelithiasis or acute or chronic cholecystitis. Patients were then tracked with unique identifiers for common bile duct injury. Common bile duct injury was identified by ICD-9 and CPT diagnosis and procedure codes for patients who subsequently underwent hepatectomy, hepaticojejunostomy, or other bile duct surgery. RESULTS: From 2005 to 2010, 156,958 patients were identified who had undergone laparoscopic cholecystectomy for symptomatic cholelithiasis or acute or chronic cholecystitis. Of the total patients, 149 patients underwent a biliary duct procedure within a year. Twenty-four of them were diagnosed with gallbladder cancer and excluded, leaving 125 for further analysis. The biliary injuries were identified at a rate of 0.080 %. Thirty-one of those patients (24.8 %) underwent hepatectomy, 40 patients (32.0 %) underwent hepaticoenterostomy, and 54 patients (43.2 %) underwent primary repair of the bile duct. Thirty-two (26 %) patients were repaired on the same day of their initial procedure. Of the remaining 93 patients, 38 (30 %) were repaired within 10 days, seven (6 %) repaired between 11 and 20 days, and 48 (38 %) patients over 21 days from injury. CONCLUSION: In NYS, the rate of bile duct injury has now decreased to 0.08 % and mirrors the historical figures quoted for open cholecystectomy. This improvement likely reflects increased experience, improved instrumentation, and movement beyond the "learning curve."

INTRODUCTION: We sought to determine the rate of revision and explant of the laparoscopic adjustable gastric banding (LAGB) over a ten-year period in the state of New York. METHODS: Following IRB approval, the SPARCS administrative database was used to identify LAGB placement from 2004 to 2010. We tracked patients who underwent band placement with subsequent removal/revision, followed by conversion to either Roux-en-Y gastric bypass (RYBG) or sleeve gastrectomy (SG) between 2004 and 2013. McNemar test and Chi-square test were used to compare complications between primary procedure and subsequent revision and to compare complication rates and mortality rates, respectively. Log-rank test was used to assess patient characteristics and comorbidities. p < 0.05 was considered significant. RESULTS: During a 7-year period, there were 19,221 records of LAGB placements and 6567 records of revisions or removal. We were able to follow up 3158 (16.43 %) who subsequently underwent a band removal or revision over the course of this period. An additional 3606 patients had no records in the state of New York following the procedure, thus making the rate of revision 20.22 %. Initial revision procedures were coded as band removal in 32.77 % (n = 1035), band revision in 30.53 % (n = 964), band removal and replacement in 19.09 % (n = 603), removal and conversion to SG in 5.64 % (n = 178), or removal and conversion to RYGB in 11.97 % (n = 378). From the 3158 patients, 2515 (79.64 %) required only one revision. Six hundred and forty-three patients underwent two or more revisions. Thirty-one out of 3158 (0.0098 %) patients had complications at their initial operation, but 919 (29.1 %) had complications during revision (p < 0.0001). CONCLUSIONS: Over a 7-year period, at least 20.22 % of LAGB required removal or revision. Based on all case numbers, total revision rate may be as high as 34.2 %. Although the band is believed to be a reversible procedure, revisional procedures are significantly more morbid than the initial procedure.
