Outcomes of Hepatic Artery-Based Therapies and Systemic Multiagent Chemotherapy in Unresectable Colorectal Liver Metastases: A Systematic Review and Meta-analysis.

BACKGROUND: Treatment of unresectable colorectal liver metastases (UCRLM) includes locoregional and systemic therapy. A comprehensive analysis capturing long-term outcomes of these treatment options has not been performed. OBJECTIVE: A systematic review and meta-analysis was performed to calculate pooled outcomes of hepatic artery infusion with systemic chemotherapy (HAI-S), transarterial chemoembolization with systemic chemotherapy (TACE-S), transarterial radioembolization with systemic chemotherapy (TARE-S), doublet (FOLFOX, FOLFIRI), and triplet chemotherapy (FOLFOXIRI). METHODS: Outcomes included overall survival (OS), progression-free survival (PFS), rate of conversion to resection (CTR), and response rate (RR). RESULTS: A total of 32, 7, 9, and 14 publications were included in the HAI-S, TACE-S, and TARE-S chemotherapy arms. The 6/12/24/36-month OS estimates for HAI-S, TACE-S, TARE-S, FOLFOX, FOLFIRI, and FOLFOXIRI were 97%/80%/54%/35%, 100%/83%/40%/14%, 82%/61%/34%/21%, 96%/83%/53%/36%, and 96%/93%/72%/55%. Similarly, the 6/12/24/36-month PFS estimates were 74%/44%/19%/14%, 66%/20%/9%/3%, 57%/23%/10%/3%, 69%/30%/12%/7%, and 88%/55%/18%/11%. The corresponding CTR and RR rates were 31, 20%, unmeasurable (TARE-S), 35, 53; and 49, 45, 45, 50, 80%, respectively. The majority of chemotherapy studies included first-line therapy and liver-only metastases, whereas most HAI-S studies were pretreated. On subgroup analysis in first-line setting with liver-only metastases, the HAI-S arm had comparable outcomes to FOLFOXIRI and outperformed doublet chemotherapy regimens. Although triplet chemotherapy appeared to outperform other arms, high toxicity and inclusion of potentially resectable patients must be considered while interpreting results. CONCLUSIONS: HAI-S and multiagent chemotherapy are effective therapies for UCRLM. To make definitive conclusions, a randomized trial with comparable patient characteristics and line of therapy will be required. The upcoming EA2222 PUMP trial may help to address this question.

Surgical Resection Alone is Associated With Higher Long-Term Survival Than Multiagent Chemotherapy Alone for Patients With Localized Biliary Tract Cancers.

INTRODUCTION: We compared long-term survival of patients with localized biliary tract cancers (BTCs) treated with either surgical resection or multiagent chemotherapy. METHODS: Patients with localized BTC [gallbladder adenocarcinoma, extrahepatic cholangiocarcinoma, intrahepatic cholangiocarcinoma] were identified within the National Cancer Database (2010-2017). Piecewise-constant hazard modeling was used to estimate hazard ratios (HRs) at prespecified intervals: 0-30 d, 31-60 d, 61-90 d, and >90 d post-treatment. RESULTS: A total of 5988 patients with localized BTC were identified: 2697 (45.0%) received multiagent chemotherapy and 3291 (55.0%) underwent surgical resection. Patients with gallbladder adenocarcinoma or extrahepatic cholangiocarcinoma who were treated with surgical resection had an associated decline in overall survival (OS) as compared to those treated with multiagent chemotherapy within 0-30 d of treatment initiation (gallbladder adenocarcinoma [adjusted HR = 3.94, 95% confidence interval [CI]: 1.77-8.80]; extrahepatic cholangiocarcinoma [adjusted HR = 4.88, 95% CI: 2.76-8.61]). However, there was an associated improvement in OS for patients treated with surgical resection after 90 d from treatment initiation (gallbladder adenocarcinoma [adjusted HR = 0.36, 95% CI: 0.28-0.46]; extrahepatic cholangiocarcinoma [adjusted HR = 0.27, 95% CI: 0.24-0.32]). Among patients with intrahepatic cholangiocarcinoma, those who underwent surgical resection had an associated improvement in OS at 31-60 d (adjusted HR = 0.63, 95% CI: 0.40-0.99) and a further associated increase in OS at 61-90 d (adjusted HR = 0.34, 95% CI: 0.21-0.54) and after 90 d (HR = 0.23, 95% CI: 0.21-0.27) of treatment initiation. CONCLUSIONS: For patients with localized BTC, surgical resection alone is associated with improved long-term survival outcomes compared to multiagent chemotherapy alone.

Comparison of Erector Spinae Plane Block and Pectointercostal Facial Plane Block for Enhanced Recovery After Sternotomy in Adult Cardiac Surgery.

OBJECTIVES: This study aimed to investigate and compare the effects of the pectointercostal fascial plane block (PIFPB) and the erector spinae plane block (ESPB) on enhancing the recovery of patients who undergo cardiac surgery. DESIGN: A randomized, controlled, double-blinded study. SETTING: The operating rooms and intensive care units of university hospitals. PARTICIPANTS: One hundred patients who were American Society of Anesthesiologists class II to III aged 18-to-70 years scheduled for elective cardiac surgery. INTERVENTIONS: Patients were randomly assigned to undergo either ultrasound-guided bilateral PIFPB or ESPB. MEASUREMENTS AND MAIN RESULTS: Patients shared comparable baseline characteristics. Time to extubation, the primary outcome, did not demonstrate a statistically significant difference between the groups, with median (95% confidence interval) values of 115 (90-120) minutes and 110 (100-120) minutes, respectively (p = 0.875). The ESPB group had a statistically significant reduced pain score postoperatively. The median (IQR) values of postoperative fentanyl consumption were statistically significantly lower in the ESPB group than in the PIFPB group (p < 0.001): 4 (4-5) versus 9 (9-11) µg/kg, respectively. In the ESPB group, the first analgesia request was given 4 hours later than in the PIFPB group (p < 0.001). Additionally, 12 (24%) patients in the PIFPB group reported nonsternal wound chest pain, compared with none in the ESPB group. The median intensive care unit length of stay for both groups was 3 days (p = 0.428). CONCLUSIONS: Erector spinae plane block and PIFPB were found to equally affect recovery after cardiac surgery, with comparable extubation times and intensive care unit length of stay.

Expert consensus on the role of supplementation in obstetrics and gynecology using modified delphi method.

PURPOSE: To reach a consensus among obstetrics and gynecology experts on the effects of micronutrient supplementation on fertility and pregnancy to aid clinicians in decision-making and create a unified approach to managing micronutrient deficiencies in women, by performing a modified Delphi study. METHODS: A three-round modified Delphi process was conducted among a Delphi panel of 38 Egyptian experts to define recommendations regarding the role of supplementation on fertility and pregnancy in women of reproductive age. A literature review was performed and supporting evidence was graded to help guide the recommendations based on available evidence. RESULTS: A total of 62 statements were developed for discussion and voting. Out of the 62 statements, 60 statements reached expert consensus. Statements were divided into two domains. The first domain discussed the role of supplementation in fertility: optimizing natural fertility, polycystic ovary syndrome (PCOS), in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI), unexplained infertility, and endometriosis, whereas the second domain was concerned with the role of supplementation in pregnancy during the prenatal, antenatal, and postnatal periods. CONCLUSION: In this work, a modified Delphi methodology was implemented to reach a consensus on the use of micronutrient supplementation in women of reproductive age. These recommendations can help clinicians in their practice, guide future research, and identify gaps in the market for the pharmaceutical industry. This clinical guidance can be extrapolated to similar communities.

Limited genetic variability and spatial population structure in grasshoppers between natural and metal-contaminated areas in Egypt.

Pollutants in an environment can have long-term implications for the species living there, resulting in local adaptations with implications for their genetic structure. Heavy metal pollutants infiltrate soils and groundwater, bioaccumulate in food webs, and negatively impact biota. In this study, we investigated the degree to which the genetic structure and variability of the slender green-winged grasshopper (Aiolopus thalassinus (Fabricius) (Orthoptera: Acrididae)) were impacted by heavy metal pollution and distance. We used the random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) method to examine the genetic variability of populations in 3 heavy metal-polluted and 3 unpolluted locations across varying geographical distances in Egypt. The heavy metal concentrations of cadmium, copper, lead, and zinc were measured from the grasshopper tissue and soils. Sixty-nine unique and polymorphic bands were produced by 4 primers. Cluster and principal component analyses separated the populations inside and outside Cairo into 2 main branches, which were further divided into smaller branches corresponding to their geographical regions. We found no differences in the Shannon genetic diversity index between populations or with increasing heavy metal concentrations in either the soil or the grasshopper tissue. Our results showed a greater genetic variation among populations than between populations within the same location, indicating populations within locations were less differentiated than those between locations. The moderate correlation between genetic similarity and spatial distance suggests geographical isolation influenced grasshopper population differentiation. Based on the RAPD analysis, environmental pollutants and geographical distances impact the A. thalassinus population structure, potentially restricting gene flow between sites even at small spatial scales.

Active Dual Line-Laser Scanning for Depth Imaging of Piled Agricultural Commodities for Itemized Processing Lines.

The accurate depth imaging of piled products provides essential perception for the automated selection of individual objects that require itemized food processing, such as fish, crabs, or fruit. Traditional depth imaging techniques, such as Time-of-Flight and stereoscopy, lack the necessary depth resolution for imaging small items, such as food commodities. Although structured light methods such as laser triangulation have high depth resolution, they depend on conveyor motion for depth scanning. This manuscript introduces an active dual line-laser scanning system for depth imaging static piled items, such as a pile of crabs on a table, eliminating the need for conveyor motion to generate high-resolution 3D images. This advancement benefits robotic perception for loading individual items from a pile for itemized food processing. Leveraging a unique geometrical configuration and laser redundancy, the dual-laser strategy overcomes occlusions while reconstructing a large field of view (FOV) from a long working distance. We achieved a depth reconstruction MSE of 0.3 mm and an STD of 0.5 mm on a symmetrical pyramid stage. The proposed system demonstrates that laser scanners can produce depth maps of complex items, such as piled Chesapeake Blue Crab and White Button mushrooms. This technology enables 3D perception for automated processing lines and offers broad applicability for quality inspection, sorting, and handling of piled products.

Long-Term Outcome of Transcutaneous Posterior Tibial Nerve Stimulation in the Treatment of Functional Non-Retentive Fecal Incontinence in Children.

BACKGROUND: Functional non-retentive fecal incontinence (FNRFI) is a psychologically upsetting and embarrassing issue and affects children's quality of life negatively. AIM OF THIS STUDY: Evaluation of the short and long-term effect of Bilateral transcutaneous posterior tibial nerve stimulation (BTPTNS) in the treatment of FNRFI in children and its impact on the quality of life (QoL). Methodology: The current randomized controlled study included 94 Children with FNRFI who were randomly allocated into two equal groups. Group A received BTPTNS and Group B Received Sham BTPTNS. Follow-up was planned for 24 months for manometric findings, incontinence score, Incontinence episodes, and the QoL. RESULTS: The incontinence score was significantly decreases in Group A more than what was reported in Group B at 6, 12, 24 months follow up . In group A 53.2% of the included children who received BTPTNS showed a decrease in the incontinence episodes more than 75% and among them, 23.4% were fully continent. All the QoL domains were significantly improved in Group A after 6, 12, and 24 months when compared with Group B. CONCLUSION: BTPTNS can be a good modality in the treatment of FNRFI with favorable long-term maintenance of its effect together with a remarkable positive impact on all domains of QoL.

Impacts of preoperative anxiety and depression on pain and range of motion after arthroscopic frozen shoulder release: a cohort study.

PURPOSE: We aimed to evaluate the impact of preoperative anxiety and depression levels on baseline and postoperative pain in patients who underwent arthroscopic frozen shoulder release. METHODS: The study included 59 patients with more than three months of idiopathic frozen shoulder. All patients had arthroscopic frozen shoulder release. Two patients were excluded from statistical analysis. Therefore, the statistical analysis was performed on the remaining 57 patients. The patients were divided into two groups according to HADS scores: group 1 which included 28 patients with a healthy psychological status (anxiety ≤ 7 and depression ≤ 7), and Group 2, which included 29 patients with psychological distress ( anxiety ≥ 8 or depression ≥ 8). RESULTS: The hallmark finding of this study is that patients complaining of frozen shoulder symptoms and having psychological distress (HADS ≥ 8) experienced higher pain scores preoperatively and at one-year follow-up after arthroscopic release. All patients showed significant improvement between the preoperative period and the one year follow-up regarding the abduction, forward flexion, external rotation at the side and the VAS pain score with a P value of 0.001. CONCLUSIONS: Arthroscopic frozen shoulder release significantly lowers the VAS pain score over the 12-month.

Chitosan-Supported ZnO Nanoparticles: Their Green Synthesis, Characterization, and Application for the Removal of Pyridoxine HCl (Vitamin B6) from Aqueous Media.

A composite of chitosan-supported ZnO nanoparticles (ZnO/CS) was green-synthesized via an easy and cost-effective method using Chicory (Cichorium intybus) plant extract. The synthesis was confirmed using uv-vis spectrometry at a λmax of 380 nm, and the surface of the material was characterized via FT-IR spectroscopy, and finally via SEM, which confirmed the distribution of ZnO nanoparticles on the surface of chitosan biopolymer (CS). The synthesized material was applied in the adsorptive removal of residues of the pyridoxine hydrochloride (vitamin B6) pharmaceutical drug from aqueous media using the batch technique. The material's removal capacity was studied through several adjustable parameters including pH, contact time, the dose of the adsorbent, and the capacity for drug adsorption under the optimal conditions. Langmuir and Freundlich isotherms were applied to describe the adsorption process. The removal was found to obey the Freundlich model, which refers to a chemisorption process. Different kinetic models were also studied for the removal process and showed that the pseudo-second-order model was more fitted, which indicates that the removal was a chemisorption process. Thermodynamic studies were also carried out. The maximum removal of vitamin B6 by the nano-ZnO/CS composite was found to be 75% at optimal conditions. The results were compared to other reported adsorbents. Reusability tests showed that the nano-ZnO/CS composite can be efficiently reused up to seven times for the removal of PDX drugs from aqueous media.

Connecting the Human Microbiome and Pancreatic Cancer.

Pancreatic cancer is a deadly disease that is increasing in incidence throughout the world. There are no clear causal factors associated with the incidence of pancreatic cancer; however, some correlation to smoking, diabetes and alcohol has been described. Recently, a few studies have linked the human microbiome (oral and gastrointestinal tract) to pancreatic cancer development. A perturbed microbiome has been shown to alter normal cells while promoting cancer-related processes such as increased cell signaling, immune system evasion and invasion. In this article, we will review in detail the alterations within the gut and oral microbiome that have been linked to pancreatic cancer and explore the ability of other microbiomes, such as the lung and skin microbiome, to contribute to disease development. Understanding ways to identify a perturbed microbiome can result in advancements in pancreatic cancer research and allow for prevention, earlier detection and alternative treatment strategies for patients.

Why the Treatment Sequence Matters: Interplay Between Chemotherapy Cycles Received, Cumulative Dose Intensity, and Survival in Resected Early-stage Pancreas Cancer.

OBJECTIVE: To define the optimal threshold of perioperative chemotherapy completion and relative dose intensity (RDI) for patients with resected pancreatic ductal adenocarcinoma (PDAC). BACKGROUND: Many patients who undergo pancreatectomy for PDAC fail to initiate or complete recommended perioperative chemotherapy. The association between the amount of perioperative chemotherapy received and overall survival (OS) is not well-defined. METHODS: Single-institution analysis of 225 patients who underwent pancreatectomy for stage I/II PDAC (2010-2021). Associations between OS, chemotherapy cycles completed, and RDI were analyzed. RESULTS: Regardless of treatment sequence, completion of ≥67% of recommended cycles was associated with improved OS compared with no chemotherapy [median OS: 34.5 vs 18.1 months; hazard ratio (HR): 0.43; 95% CI: 0.25-0.74] and <67% of cycles (median OS: 17.9 months; HR: 0.39; 95% CI: 0.24-0.64). A near-linear relationship existed between cycles completed and the RDI received (ß = 0.82). A median RDI of 56% corresponded to the completion of 67% of cycles. Receipt of ≥56% RDI was associated with improved OS compared with no chemotherapy (median OS: 35.5 vs 18.1 months; HR: 0.44; 95% CI: 0.23-0.84) and <56% RDI (median OS: 27.2 months; HR: 0.44; 95% CI: 0.20-0.96). Neoadjuvant chemotherapy is associated with increased odds of receiving ≥67% of recommended cycles (odds ratio: 2.94; 95% CI: 1.45-6.26) and ≥56% RDI (odds ratio: 4.47; 95% CI: 1.72-12.50). CONCLUSIONS: Patients with PDAC who received ≥67% of recommended chemotherapy cycles or ≥56% cumulative RDI had improved OS. Neoadjuvant therapy was associated with increased odds of receiving ≥67% of cycles and ≥56% cumulative RDI and should be considered in all patients with resectable PDAC.

Clinical and Prognostic Biomarker Value of Blood-Circulating Inflammatory Cytokines in Hepatocellular Carcinoma.

INTRODUCTION: Circulating inflammatory cytokines play critical roles in tumor-associated inflammation and immune responses. Recent data have suggested that several interleukins (ILs) mediate carcinogenesis in hepatocellular carcinoma (HCC). However, the predictive and prognostic value of circulating ILs is yet to be validated. Our study aimed to evaluate the association of the serum ILs with overall survival (OS) and clinicopathologic features in a large cohort of HCC patients. METHODS: We prospectively collected data and serum samples from 767 HCC patients treated at the University of Texas MD Anderson Cancer Center between 2001 and 2014, with a median follow-up of 67.4 months (95% confidence interval [CI]: 52.5, 83.3). Biomarker association with OS was evaluated by the log-rank method. RESULTS: The median OS in this cohort was 14.2 months (95% CI: 12, 16.1 months). Clinicopathologic features were more advanced, and OS was significantly inferior in patients with high circulating levels of IL1-R1, IL-6, IL-8, IL-10, IL-15, IL-16, and IL-18. CONCLUSION: Our study shows that several serum IL levels are valid prognostic biomarker candidates and potential targets for therapy in HCC.

Odorant-Binding Proteins and Chemosensory Proteins in Spodoptera frugiperda: From Genome-Wide Identification and Developmental Stage-Related Expression Analysis to the Perception of Host Plant Odors, Sex Pheromones, and Insecticides.

Spodoptera frugiperda is a worldwide generalist pest with remarkable adaptations to environments and stresses, including developmental stage-related behavioral and physiological adaptations, such as diverse feeding preferences, mate seeking, and pesticide resistance. Insects' odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) are essential for the chemical recognition during behavioral responses or other physiological processes. The genome-wide identification and the gene expression patterns of all these identified OBPs and CSPs across developmental stage-related S. frugiperda have not been reported. Here, we screened for genome-wide SfruOBPs and SfruCSPs, and analyzed the gene expression patterns of SfruOBPs and SfruCSPs repertoires across all developmental stages and sexes. We found 33 OBPs and 22 CSPs in the S. frugiperda genome. The majority of the SfruOBP genes were most highly expressed in the adult male or female stages, while more SfruCSP genes were highly expressed in the larval or egg stages, indicating their function complementation. The gene expression patterns of SfruOBPs and SfruCSPs revealed strong correlations with their respective phylogenic trees, indicating a correlation between function and evolution. In addition, we analyzed the chemical-competitive binding of a widely expressed protein, SfruOBP31, to host plant odorants, sex pheromones, and insecticides. Further ligands binding assay revealed a broad functional related binding spectrum of SfruOBP31 to host plant odorants, sex pheromones, and insecticides, suggesting its potential function in food, mate seeking, and pesticide resistance. These results provide guidance for future research on the development of behavioral regulators of S. frugiperda or other environmentally friendly pest-control strategies.

Disparities in guideline-compliant care for patients with pancreatic ductal adenocarcinoma at minority-versus non-minority-serving hospitals.

BACKGROUND: We examined disparities in guideline-compliant care at minority-serving hospitals (MSH) versus non-MSH among patients with localized or metastatic pancreatic adenocarcinoma (PDAC). METHODS: Patients with PDAC were identified within the National Cancer Database (2004-2018). Guideline-compliant care was defined as surgery + chemotherapy ± radiation therapy for localized and chemotherapy for metastatic disease. Facilities in the top decile of minority patients treated were considered MSH. RESULTS: A total of 190,950 patients were identified and most (59.6%) had metastatic disease. Overall, 6.4% of patients with localized and 8.2% of patients with metastatic disease were treated at MSH. Patients treated at MSH were less likely to receive guideline-compliant care (localized: OR = 0.78, 95% CI: 0.67-0.91; metastatic: OR = 0.77, 95% CI: 0.67-0.88). Minority patients were less likely to receive guideline-compliant care at non-MSH (localized: OR = 0.71, 95% CI: 0.67-0.75; metastatic: OR = 0.85, 95% CI: 0.82-0.89) or MSH (localized: OR = 0.85, 95% CI: 0.74-0.98; metastatic: OR = 0.91, 95% CI: 0.82-0.99). Patients treated at non-MSH or MSH who received guideline-compliant care were more likely to have higher OS regardless of stage or race. CONCLUSIONS: MSH patients were less likely to receive guideline-compliant care and minority patients were less likely to receive guideline-compliant care regardless of MSH status. Guideline-compliant care was associated with improved OS.

Z-shaped Miniplates vs Conventional Miniplates for Fixation of Mandibular Parasymphyseal Fractures.

AIM: The aim of this study was to evaluate a clinically and radiographically Z-shaped miniplate for the fixation of the parasymphyseal fractures. PATIENTS AND METHODS: Twenty patients (10 patients in each group) who had parasymphseal mandibular fractures were randomly selected for this study. In this study, open reduction and internal fixation were performed for mandibular parasymphyseal region fractures using two miniplates as group I, and open reduction and internal fixation were performed for mandibular parasymphyseal region fractures using a newly designed Z-shaped miniplate as group II. Clinical and radiographic evaluations were made. Each patient was evaluated: (1) clinically evaluated preoperatively and postoperatively for operating time, ease of placement of the miniplate, and occlusion and (2) radiological: postoperative reduction of fracture was evaluated radiologically at 5-day, 1-month, 2-month, and 3-month intervals with orthopantomogram, and lingual splaying was evaluated by cone-beam computed tomography (CBCT) immediately postoperatively and at an interval of 3 months. The collected data were subjected to statistical analysis. Data analysis was performed by SPSS software, version 25 (SPSS Inc., PASW statistics for Windows version 25). Chicago: SPSS Inc. RESULTS: There was a statistically significant difference (p < 0.001) between the mean intraoperative time. This indicates that group I had a longer time for fracture fixation than group II. Group I had a longer time elapsed for plate adaptation and definitive fixation than group II. Occlusion and reduction stability in both groups were similar. There was a statistically significant difference in postoperative lingual display control after 5 days and 3 months between the studied groups. This indicates that lingual display control in group II is better than in group I. CONCLUSION: The Z-shaped miniplate is effective and provides three-dimensional stability for the fixation of parasymphyseal fractures, ease of use, easily adapted in cases of fractures near the mental nerve reduced operative time, and better control of lingual splaying than conventional miniplates. CLINICAL SIGNIFICANCE: The newly designed Z-shaped miniplate is a valuable option for fixation parasymphysis fractures that need open reduction and internal fixation instead of using conventional miniplates, which are less successful in controlling lingual splaying.

Trends and disparities in the utilization of systemic chemotherapy in patients with metastatic hepato-pancreato-biliary cancers.

BACKGROUND: We described trends and disparities in utilization of systemic chemotherapy in metastatic hepato-pancreato-biliary (HPB) cancers. METHODS: We queried the National Cancer Database for metastatic HPB cancers [hepatocellular carcinoma (HCC), biliary tract cancers (BTC), pancreatic adenocarcinoma (PDAC)]. We used multivariable analysis to examine the factors associated with utilization of systemic chemotherapy. We utilized marginal structural logistic models to estimate the effect of health insurance, facility type, or facility volume on utilization of systemic chemotherapy. RESULTS: We identified 162,283 patients with metastatic HPB cancers: 23,923 (14.7%) had HCC, 26,766 (16.5%) had BTC, and 111,594 (68.8%) had PDAC. A total of 37.2% patients with HCC, 55.6% with BTC, and 56.4% with PDAC received chemotherapy. Age ≥70 years and Charlson-Deyo score ≥2 were associated with lower likelihood of receiving chemotherapy across all cancers. Patients with private health insurance had higher receipt of chemotherapy. Receiving treatment at academic facilities had no effect on the receipt of chemotherapy. Treatment of patients with HCC or PDAC at high-volume facilities resulted in higher receipt of chemotherapy. CONCLUSION: A significant proportion of patients with metastatic HPB cancers do not receive systemic chemotherapy. Several disparities in administration of chemotherapy for metastatic HPB cancers exist.

Coalition excision and corrective osteotomies versus coalition excision and arthroereisis in management of pes planovalgus with talo-calcaneal coalition in adolescents: A randomized controlled trial.

BACKGROUND: Talocalcaneal coalition is the most common cause of rigid flat foot in adolescents. It presents with recurrent ankle sprains, foot and ankle pain, and foot deformity. Management is still controversial. Multiple options were utilized during the last 40 years, including coalition excision only or coalition excision with hind foot arthrodesis or corrective osteotomies. However, the effect of arthroereisis after coalition excision is still questionable. PATIENTS AND METHODS: Thirty feet in 28 patients with rigid flat foot due to talocalcaneal coalition, who presented to our institution between September 2018 and April 2020, were prospectively analyzed. Randomization was performed by random allocation using a computer-based system into two groups: group A for coalition excision and arthroereisis, group B for coalition excision and osteotomies. Functional and radiological outcomes and complications were recorded and analyzed using Statistical Package for the Social Sciences software. RESULTS: Thirty feet in 28 patients were included in the final analysis (15 feet in each group). One patient in each group had bilateral affection. The mean age was 14.5 years, and the mean follow-up duration was 24 months. At final follow-up, the mean AOFAS was 78.8 ± 4.04 in group A and 76.73 ± 4.66 in group B, while the FAAM scores were 80 ± 5 and 79 ± 3 in groups A and B, respectively. The complication rate was higher in group A, however with no statistical significance. CONCLUSION: The combination of talocalcaneal coalition resection with either corrective osteotomies or arthroereisis had a significant improvement of functional and radiological outcomes in the management of rigid pes planovalgus.

The Role of the Microbiome in Gastroentero-Pancreatic Neuroendocrine Neoplasms (GEP-NENs).

Gut microbiome balance plays a key role in human health and maintains gut barrier integrity. Dysbiosis, referring to impaired gut microbiome, is linked to a variety of diseases, including cancers, through modulation of the inflammatory process. Most studies concentrated on adenocarcinoma of different sites with very limited information on gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs). In this study, we have analyzed the gut microbiome (both fungal and bacterial communities) in patients with metastatic GEP-NENs. Fecal samples were collected and compared with matched healthy control samples using logistic regression distances utilizing R package MatchIt (version 4.2.0, Daniel E. Ho, Stanford, CA, USA). We examined differences in microbiome profiles between GEP-NENs and control samples using small subunit (SSU) rRNA (16S), ITS1, ITS4 genomic regions for their ability to accurately characterize bacterial and fungal communities. We correlated the results with different behavioral and dietary habits, and tumor features including differentiation, grade, primary site, and therapeutic response. All tests are two-sided and p-values ≤ 0.05 were considered statistically significant. Gut samples of 34 patients (12 males, 22 females, median age 64 years) with metastatic GEP-NENs (22 small bowel, 10 pancreatic, 1 gall bladder, and 1 unknown primary) were analyzed. Twenty-nine patients had well differentiated GEP-neuroendocrine tumors (GEP-NETs), (G1 = 14, G2 = 12, G3 = 3) and five patients had poorly differentiated GEP-neuroendocrine carcinomas (GEP-NECs). Patients with GEP-NENs had significantly decreased bacterial species and increased fungi (notably Candida species, Ascomycota, and species belonging to saccharomycetes) compared to controls. Patients with GEP-NECs had significantly enriched populations of specific bacteria and fungi (such as Enterobacter hormaechei, Bacteroides fragilis and Trichosporon asahii) compared to those with GEP-NETs (p = 0.048, 0.0022 and 0.034, respectively). In addition, higher grade GEP-NETs were associated with significantly higher Bacteroides fragilis (p = 0.022), and Eggerthella lenta (p = 0.00018) species compared to lower grade tumors. There were substantial differences associated with dietary habits and therapeutic responses. This is the first study to analyze the role of the microbiome environment in patients with GEP-NENs. There were significant differences between GEP-NETs and GEP-NECs, supporting the role of the gut microbiome in the pathogenesis of these two distinct entities.

The Efficacy of Suspensory Ligament Release and Pubic Lipectomy Via Penopubic Z Plasty During Penile Prosthesis Implantation in Improving Sexual Satisfaction: A Prospective Randomized Controlled Trial.

BACKGROUND: The utility of penile suspensory ligament release (SLR) in the setting of penile prosthesis implantation (PPI) has received limited attention in the literature. AIM: To assess the efficacy and safety of penile SLR release, pubic lipectomy (PL), and the utility of penopubic Z-plasty (ZP) during malleable PPI in improving sexual satisfaction compared to that achieved with the conventional method. METHODS: Between August 2018 and April 2020, 61 patients with refractory erectile dysfunction were prospectively randomized into 2 groups; group A included 31 patients who underwent PPI with SLR and PL via ZP, and group B included 30 patients who underwent conventional PPI via a penoscrotal incision. OUTCOMES: Penile length was assessed at 3 months, and sexual satisfaction was assessed up to 1 year after PPI using both validated and non-validated tools. RESULTS: The median operative time was higher in group A than in group B (170 min; interquartile range [IQR] [160-190] vs 97.5 min; IQR [90-110] P < .001).The median pre- to postoperative differences in functional and visible penile lengths for group A were 1.5 cm; IQR [0-2] and 2.5 cm; IQR [1-3.5], respectively, while those in group B were both 0 cm; IQR [-1 to 0] P < .001). Group A patients reported higher scores in the International Index of Erectile Function satisfaction domains than the group B patients did (13; IQR [12-14] and 9; IQR [8-10] vs 11; IQR [9.5-12] and 8; IQR [6.5-8.5], respectively, P < .001). Moreover, the postoperative Erectile Dysfunction Inventory of Treatment Satisfaction score was higher in group A than that in group B (95.40; IQR [91-97.7] vs 85.20; IQR [72.7-91], respectively, P < .001). Common complications in group A were penile edema (77.4%), penile instability (9.7%) and glans numbness (9.7%). CLINICAL IMPLICATIONS: The benefit in patient satisfaction following SLR and PL via ZP during PPI may outweigh the incremental increase in complications. STRENGTH & LIMITATIONS: To our knowledge, this is the first prospective randomized controlled study to evaluate the efficacy and safety of SLR, PL, and ZP during PPI. However, because an optimal tool for assessing sexual satisfaction after PPI is lacking at this time, we alternatively adopted the most used assessment tools. Further, our data applies only to malleable penile prosthesis. CONCLUSION: SLR and PL via ZP during PPI resulted in a substantial improvement of the patients' sexual satisfaction without serious complications. Fotouh El Gharably MA, Ghoneima W, Lotfi MR, et al.
