Clinical study of different interventional treatments for primary hepatocellular carcinoma based on propensity-score matching

BACKGROUND Transcatheter arterial chemoembolization (TACE) is the main treatment for patients with primary hepatocellular carcinoma (PHC) who miss the opportunity to undergo surgery. Conventional TACE (c-TACE) uses iodized oil as an embolic agent, which is easily washed by blood and affects its efficacy. Drug-eluting bead TACE (DEB-TACE) can sustainably release chemotherapeutic drugs and has a long embolization time. However, the clinical characteristics of patients before the two types of interventional therapies may differ, possibly affecting the conclusion. Only a few studies have compared these two interventions using propensity-score matching (PSM). AIM To analyze the clinical effects of DEB-TACE and c-TACE on patients with PHC based on PSM. METHODS Patients with PHC admitted to Dangyang People’s Hospital (March 2020 to March 2024) were retrospectively enrolled and categorized into groups A (DEB-TACE, n = 125) and B (c-TACE, n = 106). Sex, age, Child-Pugh grade, tumor-node-metastasis stage, and Eastern Cooperative Oncology Group score were selected for 1:1 PSM. Eighty-six patients each were included post-matching. Clinical efficacy, liver function indices (aspartate aminotransferase, alanine aminotransferase, total bilirubin, and albumin), tumor serum markers, and adverse reactions were compared between the groups. RESULTS The objective response and disease control rates were significantly higher in group A (80.23% and 97.67%, respectively) than in group B (60.47% and 87.21%, respectively) (P < 0.05). Post-treatment levels of aspartate aminotransferase, alanine aminotransferase, and total bilirubin were lower in group A than in group B (P < 0.05), whereas post-treatment levels of albumin in group A were comparable to those in group B (P > 0.05). Post-treatment levels of tumor serum markers were significantly lower in group A than in group B (P < 0.05). Patients in groups A and B had mild-to-moderate fever and vomiting symptoms, which improved with conservative treatment. The total incidence of adverse reactions was significantly higher in group B (22.09%) than in group A (6.97%) (P < 0.05). CONCLUSION DEB-TACE has obvious therapeutic effects on patients with PHC. It can improve liver function indices and tumor markers of patients without increasing the rate of liver toxicity or adverse reactions.

Abstract PR004: Age-induced chronic accumulation of glucocorticoids drives therapy resistance in lung cancer

Abstract Non-small cell lung cancer (NSCLC), a highly aggressive cancer, is the leading cause of cancer- related deaths in the U.S. While chemotherapy and targeted therapy are the main treatment modalities in the clinic, many patients do not respond to these treatments. Strikingly, the median age for lung cancer diagnosis is 71. Yet, preclinical and clinical research have largely been skewed towards young mice and patients. Here, we address this gap in knowledge and evaluate if old age affects the response to standard of care NSCLC therapies in KRAS-driven NSCLC. Using human sera from young and old healthy subjects to treat NSCLC cell lines, we show that age-driven circulatory changes are sufficient to drive a state of profound resistance to both chemotherapies as well as KRASG12C targeted therapies. We confirmed the relevance of our findings in vivo, by transplanting cancer cells derived from the K-rasLSL-G12D/+; p53fl/fl genetically engineered mouse model of lung cancer into young and old C57BL/6 mice. Using this model we showed that unlike young lung tumor-bearing mice on chemotherapy, old tumor-bearing mice do not respond to treatment and have a poor prognosis. Mechanistically, we found that old age drives a transcriptional reprogramming that favors drug resistance and identified the glucocorticoid receptor as a major driver of these transcriptional changes. We traced this to an age-induced chronic accumulation of glucocorticoids in circulation and within the tumor interstitial fluid. Chronic treatment with age-relevant concentrations of cortisol alone was sufficient to drive glucocorticoid receptor activation and induce resistance to therapies mirroring the effects of old age. Further supporting a driving role for glucocorticoids in driving age- induced drug resistance, blocking the glucocorticoid receptor genetically or pharmacologically rescues the drug resistance state imposed by old age in NSCLC cells. Lastly, using TCGA patient data we show an inverse correlation between glucocorticoid receptor activation (GR score) and progression-free survival of lung cancer patients. Together, our work demonstrates a role for age-induced glucocorticoids in circulation in promoting therapy-resistance in NSCLC patients and supports the use of therapeutic agents that block the glucocorticoid receptor as a strategy to increase therapy efficacy in NSCLC patients.

Cisternostomy associated with decompressive craniectomy for traumatic brain injury: a systematic review and meta-analysis.

Decompressive craniectomy (DC) has been the main surgical treatment of refractory high intracranial pressure (ICP) in traumatic brain injury (TBI) for decades. Basal cisternostomy emerged as a novel option in brain trauma, with results still unclear. We performed a systematic review and meta-analysis comparing cisternostomy added to conventional DC versus DC alone for the treatment of TBI. This study was designed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. Three databases were systematically searched for studies comparing cisternostomy + DC versus DC alone. Primary outcomes were overall mortality, length of stay in ICU care, duration of mechanical ventilation. Review Manager was used for statistical analysis and I2 measured heterogeneity. A total of seven studies and 980 patients were included in this meta-analysis, 473 in the cisternostomy + DC group and 507 in the DC group. Age ranged from 14 to 69 years old, with 76% male patients. Overall mortality was significantly lower in the cisternostomy + DC group (OR 0.70; 95% CI 0.53-0.92; p = 0.01; I2 = 31%). Length of stay in ICU care was significantly reduced in the patients submitted to cisternostomy + DC (OR -4.58; CI -6.78, -2.37); p < 0.0001; I2 = 35%). The mean duration in mechanical ventilation was significantly lower in the group submitted to cisternostomy + DC (-3.49; 95% CI-6.79, -0.20; p = 0.04; I2 = 86%). Regarding functional outcomes, the scarce and heterogeneous data were not sufficient to make any conclusion about the effect of cisternostomy on functional outcomes, but tends to favor patients who underwent cisternostomy combined with DC. In this meta-analysis, the implementation of cisternostomy added to conventional DC was associated with lower mortality, days in mechanical ventilation and length of stay in ICU care. Larger prospective and randomized cohorts are necessary to recommend this procedure on a large scale.

Monitoring and Treatment of Paroxysmal Nocturnal Hemoglobinuria in Patients with Aplastic Anemia in Asia: An Expert Consensus

Paroxysmal nocturnal hemoglobinuria (PNH) clones can be identified in a significant proportion of patients with aplastic anemia (AA). Screening for PNH clones at the time of an AA diagnosis is recommended by national and international guidelines. In this report, an expert panel of physicians discusses current best practices and provides recommendations for managing PNH in patients with AA in the Asia–Pacific region. Plasma/serum lactate dehydrogenase (LDH) levels and reticulocyte count should be measured with every blood test. PNH clone size should be monitored regularly by flow cytometry, with on-demand testing in the event of a rise in LDH level ± reticulocyte count or development of symptoms such as thrombosis. Monitoring for PNH clones can guide the choice of initial AA treatment, although flow cytometry has resource implications which may present a challenge in some Asia–Pacific countries. The treatment of patients with both PNH and AA depends on which condition predominates; following PNH treatment guidelines if hemolysis is the main symptom and AA treatment guidelines if bone marrow failure is severe (regardless of whether hemolysis is mild or moderate). The expert panel’s recommendations on the monitoring and treatment of PNH in patients with AA are practical for healthcare systems in the Asia–Pacific region.

BN SO17 - When cholecystectomies go wrong: A single-centre review of post-operative complications over a two year period

Abstract Background Laparoscopic cholecystectomy (LC) is the main treatment for symptomatic gallstone disease with around 70,000 performed in the UK each year. The majority of these are day case procedures and patients recover well, however, there will always be a risk of more serious complication which can have serious negative effects on patients. The Clavien-Dindo classification of surgical complications is the most recognised method of grading post-operative complications by severity. The aim of our study was to identify our rates and severity of post-operative complication and their management. Method All patients who had LC between 1st July 2020 and 30th June 2022 were identified. Patient and operative details were retrieved from their electronic record. A complication was defined as any deviation from the standard post-operative course and was graded according to the Clavien-Dindo classification. 30-day readmission data was collected via hospital episode statistics and outcomes were reviewed on the patient record. Results 974 patients underwent LC. 30-day morbidity = 8.9%, 30-day readmission = 4.8% and 30-day mortality = 0.31%. Clavien-Dindo grade of complication: Grade 1= 44.7%, Grade 2 = 22.4%, Grade 3A = 12.9%, Grade 3B = 11.8%, Grade 4A = 1.2%, Grade 4B = 1.2%; and Grade 5 = 3.5%. 11 patients (1.1%) returned to theatre; bile leak was the most common indication (73%). Two intra-operative bile duct injuries were observed (0.21%) with one managed locally and the other transferred to the regional HPB centre. 7 patients required post-operative ERCP (0.72%), 57% for CBD stones and 43% for persistent bile leak. Conclusion Our study showed that the majority of post-operative morbidity following LC is related to post-operative pain (2.9%) or simple wound infection (1.8%). 2.6% of patients who underwent LC during had a significant complication requiring surgical, endoscopic or radiological intervention or admission to intensive care (Clavien-Dindo &amp;gt; 2). We report a 0.21% risk of bile duct injury and a 0.92% risk of post-operative bile leak. Overall our findings are in keeping with other studies but provide an insight into our local practice and that an area of potential improvement would be better management of post-operative pain.

BN SO20 - Day-case laparoscopic cholecystectomy: Predictors of failure

Abstract Background Laparoscopic Cholecystectomy (LC) is the main treatment option for symptomatic gallstone disease. It is commonly performed as a day case operation and Getting It Right First Time (GIRFT) have suggested that this should be the default position for all trusts. NHSE Model Hospital analyses hospital metrics and sets national benchmarks. They suggest that the day case rate for LC should be greater than 71.4%. The aim of our study is to analyse all elective LC’s over a two year period and identify factors that increase the likelihood of day-case failure and the common reasons for this. Method All patients who had LC between 1st July 2020 and 30th June 2022 were identified. All emergency cholecystectomies were excluded from analysis. Patient and operative details were retrieved from their electronic record and a Charlson co-morbidity index was calculated. Statistical analysis was performed using SPSS with Chi-squared tests performed for categorical data and ANOVA for continuous data. Odds ratios with 95% confidence intervals were calculated. Statistical significance was taken as p&amp;lt;0.05. Results 788 patients had elective cholecystectomies with 74.0% being successful day-case. Factors increasing day-case failure included: Admission with gallbladder disease within past year (OR 3.15 (2.26-4.37), CBD diameter&amp;gt;8mm (OR 2.17(1.44-3.26), thick-walled gallbladder (OR 2.20(1.59-3.04), on-table cholangiogram (OR 4.16 (2.21-7.84), sub-total cholecystectomy (OR 30.6(9.19-102) and male sex (OR 1.55(1.11-2.18). Patients who failed day-case had higher mean age (59 vs 49) and higher co-morbidity index (2.16 vs 1.44). The most common reasons for day-case failure were complex procedure (41%), and symptom control (35%). Only 20% had planned admissions. 30-day morbidity and re-admission rate were higher for failed day-case patients. Conclusion Our hospital complies with the day case benchmark set out by Model Hospital. Furthermore, only 5.2% of patients undergoing elective cholecystectomy had a pre-operative decision for an inpatient stay demonstrating that day case is the default for the vast majority of patients. Despite this, improvement could still be made with post-operative symptom control to try and increase this number further.

BN SO21 - Factors influencing subtotal cholecystectomy

Abstract Background Laparoscopic Cholecystectomy (LC) is the main treatment for symptomatic gallstone disease. Sub-total cholecystectomy (SC) has become increasingly utilised as a safe alternative to conversion to open when unable to visualise the critical view of safety. This avoids the morbidity of an open operation whilst minimising the risk of iatrogenic injury to the common bile duct. Male sex, increasing age, previous acute cholecystitis and ERCP have previously been identified as independent risk factors for SC. We aim to identify factors that increased the likelihood of SC within our cohort and the effect of SC on post-operative morbidity. Method All patients who had LC as either an elective or emergency procedure between 1st July 2020 and 30th June 2022 were identified and included in this study. Patient and operative details were retrieved from their electronic record and a Charlson co-morbidity index was calculated. Any post-operative complication was noted and graded according to the Clavien-Dindo classification. Statistical analysis was performed using SPSS with ANOVA analysis being performed for continuous data. Odds ratios were calculated with a 95% confidence interval. Statistical significance was taken as a p value &amp;lt; 0.05. Results 974 patients underwent LC with 4.8% having SC. Factors associated with increased risk of SC included: previous acute cholecystitis (OR 9.37 (4.69-18.70), increased age (mean = 58.7 vs 50.9), higher Charlson co-morbidity index (mean = 2.60 vs 1.43) male sex (OR 2.49 (1.38-4.48), emergency operation (OR 2.30 (1.23-4.30), Diabetes Mellitus (OR 2.58 (1.23-5.36); and previous ERCP (OR 2.62 (1.13-6.11). 30-day morbidity was higher for SC (25.5% vs 8.1%) with major complication (Clavien-Dindo &amp;gt; 2) being significantly more frequent (OR 6.64(2.53-17.4). Median post-operative length of stay was 2 days for SC and 0 days for LC. Conclusion Although regarded as a safe option in difficult cholecystectomy, our study shows that there is significant morbidity associated with subtotal cholecystectomy. However, the majority of patients only require a short hospital stay post-operatively. Multiple risk factors were identified for SC with previous acute cholecystitis being the most strongly associated with SC. Diabetes was identified as an independent risk factor alongside higher Charlson co-morbidity index as a generic marker of co-morbidity. Interestingly, CBD diameter &amp;gt; 8mm on pre-operative imaging was not shown to increase risk of SC.

EGS SO08 - How best to time the operative management of acute cholecystitis: Is there a difference in outcomes between hot and smouldering cholecystectomy?

Abstract Background Laparoscopic Cholecystectomy (LC) is the main treatment for symptomatic gallstone disease. Acute cholecystitis (AC) is a common emergency presentation in the UK and the 2015 AUGIS guidelines recommend emergency cholecystectomy within 72 hours of admission if the patient is fit. On a practical level this can sometimes be difficult to implement and often patients are discharged to return for an elective procedure (the smouldering gallbladder). We aimed to analyse our practice at a large district general hospital for the management of patients with AC and their post-operative outcomes. Method All patients undergoing LC between 1st July 2020 and 30th June 2022 were identified. Patients with an ICD-10 code of K81 (AC) associated with an inpatient stay within a year of their operation were included. Those admitted and operated on during that admission were classified as hot cholecystectomies (HC), whereas those admitted and discharged for an elective procedure were termed smouldering cholecystectomies (SC). Patient and operative details were retrieved from their electronic record and a Charlson co-morbidity index was calculated. Statistical analysis was performed using SPSS with Chi-squared tests performed for categorical data and ANOVA for continuous data. Results 276 patients underwent cholecystectomy for AC with 52.2% elective and 47.8% emergency (91% within 72 hours of admission). HC patients were younger (52.3 vs. 57.5, p&amp;lt;0.01) and less-comorbid (1.67 vs 2.12, p&amp;lt;0.05). The subtotal cholecystectomy rate was comparable between the groups (9.8% vs 16.0%, p=0.131). HC patients had more post-operative drains (38.6% vs 27.1%, p&amp;lt;0.05) and thick-walled gallbladders (92.4% vs 64.6%, p&amp;lt;0.001). Median post-operative length of stay was 1 day for HC and 0 days for SC. No difference was observed for 30-day readmission (4.5% vs 7.6%, p=0.286), morbidity (12.9% vs 11.8%, p=0.786) or mortality (0.8% vs 0.7%, p=0.951). Conclusion This study adds to the evidence that emergency cholecystectomy is as safe an option as discharging patients to return for an elective procedure in the future. Although a proportion of those discharged to return for an elective operation will have thin-walled gallbladders, the rate of subtotal cholecystectomy remains similar, if not slightly higher in the elective group (although not reaching statistical significance). Most emergency cholecystectomy patients were discharged the following day, therefore demonstrating that they do not significantly contribute to bed blocking and reduce the burden on already strained elective waiting lists.

Impact of Levels of Nutrient Management on Economics of Soybean-onion and Soybean-potato Cropping System

Background: Nutrient management and cropping sequence are two important factors which affect productivity and profitability of crop. Profitability is one the important part of the successful crop production. Soybean fixes atmospheric nitrogen in soil and partially fulfills the nitrogen requirement of succeeding crops. There is a need for a suitable substitute crop or cropping systems after soybean to improve the soil fertility and productivity to maximize the profitability. The plains of Maharashtra are well suited for onion and potato cultivation. There is scope for increasing the area, production and productivity of onion and potato crop. Majority of farmers in Maharashtra following soybean-wheat and soybean-chickpea crop sequence while in present investigation soybean is grown in sequence with vegetable crop such as onion and potato which could help to increase profitability through higher net return and B: C ratio. Methods: The experiment was laid out in split plot design with three replications. Six combinations of two crop sequences (soybean-onion and soybean-potato) and three levels of nutrient management viz., 50% RDF+FYM 5 t ha-1+ biofertilizer (N1), 75 % RDF+ FYM 5 t ha-1+ biofertilizer (N2) and 100 % RDF+ FYM 5 t ha-1+ biofertilizer (N3) were the main plot treatments in kharif season replicated three times in randomized block design. During rabi season each main plot treatment of nutrient management level was split into three sub plot treatments with three levels of recommended dose of fertilizer viz., 75% RDF (F1), 100% RDF (F2) and 125% RDF (F3) to rabi season crops resulting in eighteen treatment combinations replicated three times in split plot design. The data pertaining to growth characteristics, yield characteristics, economics of soybean (kharif) and onion or potato (rabi) was collected at regular interval in 2017-18, 2018-19 and 2019-20 at Agronomy Farm, Dr. PDKV, Akola which was analyzed statistically in SPD (split plot design). Result: Soybean-onion crop sequence registered higher profitability in terms of GMR, NMR and B: C in comparison with soybean - potato crop sequence. Soybean crop supplied with 100% RDN+ 5 t FYM ha-1 + Biofertilizer (Rhizobium japonicum+ PSB+ Tricoderma viridi) recorded highest GMR, NMR and B:C ratio over lower levels of treatments in all year experimentation. Rabi crops treated with 125% RDF recorded GMR, NMR and B:C ratio over lower levels of treatments in all years of experimentation.

Atrazine application shapes white leaf spot (Neopseudocercosporella capsellae) development on triazine-resistant canola

Studies were undertaken on two atrazine-tolerant canola (Brassica napus) cultivars (moderately resistant Crusher TT and highly susceptible Thunder TT) to white leaf spot (WLS) (Neopseudocercosporella capsellae), to determine how atrazine application affects WLS development. There were significant main treatment effects in relation to percent leaf disease incidence (%LDI), percent leaf area diseased (%LAD) and percent leaf area collapsed (%LAC) for canola cultivar, disease development period (days-post-inoculation), atrazine spray (before or after inoculation), and %LDI for atrazine spray timing (0, 1, 3, 7 days), along with significant two- and three-way interactions between treatments. For %LDI across a 21-day period, Crusher TT showed greatest disease suppression from atrazine application 0 or 7 days before inoculation, and Thunder TT from application 0 days before and 7 days after inoculation. In terms of %LAD, Crusher TT showed greatest suppression from application at 0 and 7 days before inoculation, and Thunder TT from application 0 days before or 1 day after inoculation. In relation to %LAC, Crusher TT showed greatest suppression from application 7 days before inoculation and Thunder from application 0 days before or 1 day after inoculation. That the extent of suppression of WLS by atrazine application was substantial and that it varied with cultivar susceptibility, application timing, and that there was a strong interaction of cultivar x application timing, highlights potential opportunities for farmers to exploit better cultivar choices in conjunction with manipulating the timing of atrazine application to maximize WLS suppression and consequent canola yield.

A Clinicopathological Study of Scrotal Calcinosis and Literature Review.

Objective. We aimed to investigate the clinicopathological features and pathogenesis of scrotal calcinosis. Methods. Hematoxylin and eosin (HE)-stained slides were performed on 14 patients with scrotal calcinosis, and the clinicopathological characteristics were analyzed together with clinical data. Meanwhile, 81 patients with extrascrotal calcinosis cutis and 7480 patients with epidermoid cysts without calcification in the skin of various parts of the body were collected and analyzed to explore the etiology and pathogenesis of scrotal calcinosis in conjunction with the literature review. Results. All our patients were adult men with a mean age of 38.2 years, with clinical manifestations of multiple scrotal nodules of varying sizes, microscopically characterized by intradermal calcium deposits, of which 3 lesions had a cystic cavity lined with squamous epithelium. Conclusions. Scrotal calcinosis is a rare benign disease that presents clinically as single or multiple hard nodules in the scrotum, usually asymptomatic, and it is histopathologically characterized by intradermal calcium deposition. There is still controversy as to whether it is idiopathic. We believe that scrotal calcinosis is not idiopathic and originates from epidermoid cysts. Prolonged local compression or injury may be one reason for the development of calcification, and perhaps there are other unknown factors contributing to the development of the disease. Surgical excision is the main treatment for this disease with satisfactory therapeutic effectiveness.

Ovarian Steroid Cell Tumor About a Case

Tumors of the sex cords and stroma of the ovary are relatively rare, accounting for around 8% of all primary ovarian tumors. Steroid cell tumors of the ovary are rare, accounting for less than 0.1% of all ovarian tumors. The majority of these tumors produce steroid hormones, and only 10-15% of patients are asymptomatic. Although steroid cell tumors are generally benign, there is a risk of malignant transformation. Surgery is the main treatment. We report a case of a steroid cell tumour of the left ovary discovered on anatomopathological examination of the left adnexectomy operative specimen in a 47-year-old hypertensive diabetic patient who clinically presented with virilism with severe hirsutism, muscular and clitoral hypertrophy and frontotemporal baldness, and biologically increased androgens without associated hypercorticism, and in whom an abdomino-pelvic scanner showed a left latero-uterine mass measuring 74x66x64 mm, pelvic MRI showed a polylobed left ovarian mass classified ORADS 5, measuring 53x65x87 mm. After histological confirmation of the diagnosis, the patient was taken back for total surgery with total hysterectomy, right adnexectomy, omentectomy, appendectomy, multiple peritoneal biopsies, with no signs of malignancy on histological examination, simple postoperative follow-up and our patient placed under surveillance.

Arthroscopic Management of Juxta-Articular Proximal Tibial Chondroblastoma: A Case Report and Literature Review.

Chondroblastoma is a rare bone tumor that originates from the epiphysis, constitutes around 1% of all primary bone tumors and is recognized for its tendency to exhibit local invasiveness, as well as the possibility of metastasis and recurrence in nearby areas. Currently, the main surgical treatment for chondroblastoma is open surgery, involving excision of the lesion. There are relatively few reports on arthroscopic surgery for the treatment of chondroblastoma. However, open surgical curettage is associated with operation-related trauma and potential for damage to the osteoepiphysis resulting in growth disturbances. This case study presents the application of an arthroscopic technique in a 14-year-old male patient with chondroblastoma affecting the proximal tibia and tibial eminence. The procedure involved thorough removal of the lesion using direct visualization with the management of the cavity utilizing a substitute for autologous bone graft. After 1 year of follow-up, the patient remains free from symptoms, exhibits normal knee functionality, and radiographic analysis reveals a good autologous bone graft fusion without any signs of recurrence. Based on the existing cases of arthroscopic treatment for chondroblastoma and the report of this case, arthroscopic treatment for chondroblastoma can be considered as a specific treatment option for certain patients. In some cases, this technique could be an effective alternative to open surgery.

Biphenotypic Sinonasal Sarcoma: Literature Review of a Peculiar Pathological Entity—The Neurosurgical Point of View

Background: Biphenotypic sinonasal sarcoma (BSNS) is a low-grade tumor of the sinonasal tract with frequent extension to the orbit and skull base. Due to its rare incidence and recent histopathological and molecular characterization, little data are available in regard to its natural history, treatment and surveillance protocol. Methods: A comprehensive literature review in Embase online electronic databases on BSNS was made. The analyzed factors included the patients’ sex and age, presenting symptoms and signs, anatomical origin and pattern of growth of the tumor, immunohistochemical and molecular features, time to treatment, type of treatment, surgical approach, extent of resection, peri- and post-operative complications, adjuvant therapies, clinical outcome, recurrence and overall survival rates. Results: This literature review involved 34 studies for an overall series of 149 cases of BSNS. The female (66.9%) and middle-aged populations (median 54.88 years old) were mainly affected. The most frequent clinical onset was nasal obstruction (81%), followed by facial discomfort (44%), epistaxis (15.5%) and ocular impairment (14.3%). Ethmoid sinus (67.8%) and nasal cavity (45.4%) were the most common anatomical site of tumor origin, while an extension to the orbit and skull base was registered in 28.7% and 24.5% of cases. Surgery was the main treatment, especially in the form of endoscopic endonasal approach (56.9%), and allowed for gross total resection in 79% of cases. The recurrence rate was 26.2%; three cases of tumor-related death were reported. Median follow-up was 4.6 years. Conclusions: Biphenotypic sinonasal sarcoma is a rare and unique tumoral entity in terms of biological and clinical behavior. Based on the current knowledge, surgery plays the leading role in treatment, accounting for gross total tumor resection in most cases, allowing for clinical symptom and sign resolution and presenting a low rate of perioperative complications. The type of approach and the aim of surgery should be assessed case by case according to patient and pathology features and the surgeon’s experience, as well as the aim of the treatment. Further studies including large surgical series and with long follow-up are required to define prognostic factors and guidelines of treatment for this peculiar pathological entity.

Case report: How I do it? Laparoscopic hepatectomy with transcatheter arterial ICG staining for hepatolithiasis review

BackgroundHepatolithiasis is regarded as the presence of stones in the intrahepatic bile ducts. Recurrent inflammation of bile ducts can bring many bad effects. How to completely remove stones is still a challenge.PresentationA 66-year-old male went to our hospital because of hepatolithiasis and choledocholithiasis. Selective hepatic arteriography and transcatheter arterial embolization followed by laparoscopic watershed hepatectomy under fluorescent navigation and laparoscopic common bile duct exploration on mass removal are performed.Clinical discussionFor patients who suffer from hepatolithiasis, the main treatment principles of the operation are to remove the stones, correct the stenosis, and prevent recurrence. The laparoscopic watershed hepatectomy under fluorescent navigation can provide important support for precision liver surgery, which can give some suggestions for future hepatectomy.ConclusionBased on the three-dimensional (3D) visual watershed analysis, trans-arterial DSA positive fluorescence navigation has some advantages, which successfully overcome the shortcomings of the reverse staining method and the positive staining method.

Efficacy of a WeChat-Based, Multidisciplinary, Full-Course Nutritional Management Program on the Nutritional Status of Patients With Ovarian Cancer Undergoing Chemotherapy: Randomized Controlled Trial.

As the most malignant type of cancer in the female reproductive system, ovarian cancer (OC) has become the second leading cause of death among Chinese women. Chemotherapy is the main treatment for patients with OC, and its numerous adverse effects can easily lead to malnutrition. It is difficult to centrally manage patients with OC in the intervals between chemotherapy. The use of WeChat, an effective mobile tool, in chronic disease management has been highlighted. This study aimed to implement a continuous follow-up strategy and health monitoring based on the WeChat platform for patients with OC undergoing chemotherapy to ensure that each phase of chemotherapy was delivered on schedule and to improve the survival rate of patients with OC. Participants were recruited and randomly assigned to either the WeChat-based nutrition intervention group or the usual care group. A self-administered general information questionnaire was used at enrollment to obtain basic information about the patients. The Patient-Generated Subjective Global Assessment (PG-SGA) Scale was used to investigate the nutritional status of the patients at 3 time points (T0=before the first admission to the hospital for chemotherapy, T1=2 weeks after the first chemotherapy, and T6=2 weeks after the sixth chemotherapy). The blood indices of patients were investigated through the inhospital health care system at 3 times（T0=before the first admission to the hospital for chemotherapy, T1=2 weeks after the first chemotherapy, and T6=2 weeks after the sixth chemotherapy). Patients in the intervention group were introduced to the nutrition applet, invited to join the nutrition management group chat, and allowed to consult on nutritional issues in private chats with nutrition management team members. Linear mixed models were used to analyze changes in each nutritional indicator in the 2 groups, with their baseline measurements as covariates; with group, time, and group-time interactions considered as fixed effects; and with patients considered as random effects. A total of 96 patients with OC undergoing chemotherapy were recruited into the study. Distribution was based on a 1:1 ratio, with 48 patients each in the nutrition intervention group and the usual care group. The attrition rate after the first chemotherapy session was 18.75%. The mixed linear model revealed that the group-based effect and the group-time interaction effect on PG-SGA scores were significant (F38,38=4.763, P=.03; F37,37=6.368, P=.01), whereas the time-based effect on PG-SGA scores was not (F38,38=0.377; P=.54). The findings indicated that the group-based effect, the time-based effect, and the group-time interaction effect on nutrition-inflammation composite indices were significant (F38,38=7.653, P=.006; F38,38=13.309, P<.001; F37,37=92.304, P<.001; F37,38=110.675, P<.001; F38,38=10.379, P=.002; and F37,37=5.289, P=.02). This study provided evidence that a WeChat-based, multidisciplinary, full-course nutritional management program can significantly improve the nutritional status of patients with OC during chemotherapy.

Zoledronate Therapy in Osteogenesis Imperfecta: Perspectives in Indonesia Tertiary Hospital.

Osteogenesis imperfecta (OI) is a rare disease with an estimated incidence of between 1/25,000 and 1/10,000 globally. The main treatment for OI is the administration of bisphosphonate drugs. Research on clinical, radiographic, and biochemical markers to monitor patients with OI treated with zoledronate can be challenging in countries in which patients have limited national health insurance. We aimed to examine patients with OI treated in Indonesia with a minimum follow-up period of 2 years. An observational study was conducted of all patients with OI treated with zoledronate between 2021 and 2023 at a tertiary hospital in Indonesia. We evaluated the paediatric quality of life (PedsQL), bone mineral density (BMD), and alkaline phosphatase (ALP) level before and after zoledronate treatment. To monitor safety, serum creatinine and calcium levels were also measured. Eleven boys (55%) and nine girls (45%), with an average age of 6.9 years (range, 4-17 years), were included. After 2 years of zoledronate treatment, the total PedsQL score increased from 66.7 to 76.9 (P=0.0001) and the mean lumbar and total body BMD increased from 0.467 and 0.501 to 0.599 g/cm2, and 0.626 g/cm2 (P=0.001), respectively. The ALP level decreased from 310.6 to 186.4 mg/mL (P=0.0001). Neither serum creatinine (P=0.586) nor calcium (P=0.53) levels changed from the pre-treatment to 2 years post-treatment time points. Zoledronate was safe and effective for the treatment of OI. There were significant improvements in the quality of life and BMD in patients with OI. The ALP level decreased, but serum creatinine and calcium levels were not affected by zoledronate.

Antiviral therapy for cytomegalovirus retinitis: A systematic review and meta-analysis.

Cytomegalovirus retinitis (CMVR) is a significant cause of blindness in patients with advanced acquired immunodeficiency syndrome (AIDS). There are no established guidelines for its treatment, resulting in varied antiviral approaches. We pooled data from 59 studies (4,501 patients) to evaluate treatment variations and outcomes (CRD42022321088). Overall pooled estimates showed visual acuity improvement at 18% (95% CI: 7-41%), inflammation resolution at 90% (95% CI: 81-95%), retinal detachment at 11% (95% CI: 8-14%), and recurrence at 19% (95% CI: 11-31%). The main antiviral treatment approaches identified were: (1) intravenous antivirals alone in 33 studies, (2) intravitreal antivirals alone in 26 studies, (3) oral antivirals alone in 3 studies, and (4) a combination of systemic (oral or intravenous[IV]) and intravitreal antivirals in 7 studies, with varying schemes and durations. Ganciclovir was the predominant antiviral, with intravenous administration being the most reported (in 23 studies), followed by intravitreal administration (in 20 studies). While visual acuity improvement was comparable, inflammation resolution tended to be higher with intravitreal than with IV antivirals, though not statistically significant (88%, 95% CI: 69-96% vs 75%, 95% CI: 35-94%, p = 0.38). Retinitis progression rate for IV ganciclovir was lower than for those without ganciclovir. Inflammation recurrence was significantly lower in antiretroviral (ART)-treated compared to non-ART-treated HIV/AIDS patients (10% (95% CI: 4-20%) vs 33% (95% CI: 19-50%), p < 0.01). Neutropenia, particularly with ganciclovir, was the most reported adverse effect (up to 50%).

Mesh-associated pain syndrome: predictors for continence and prolapse mesh removal surgery in a single centre

ObjectiveOver the last two decades one of the main surgical treatment for stress urinary incontinence (SUI) and pelvic organ prolapse (POP) surgery was the insertion of non-absorbable mesh to restore continence and prolapse respectively. Over time complications arose including mesh-associated pain syndrome (MAPS), mesh exposure, mesh, erosion, chronic bladder/vaginal infections, and dyspareunia. Consequently, women chose surgical mesh removal to counter these problems. However, little is known about the demographics, medical co-morbidities, mesh types involved and the timing from mesh insertion to mesh removal. This retrospective study will look at which of these factors may be closely associated with mesh removal surgery.DesignRetrospective evaluation.SettingFemale Pelvic Medicine and Reconstructive Surgery (FPMRS) Clinic at University College London Hospitals NHS Foundation Trust.PopulationAll patients presenting to the FPMRS Clinic between June 2011 to December 2019, requesting mesh removal surgery with a history of MAPS and other mesh complications were included in this study.MethodsPatient demographics including age, ethnicity, obstetric history, and medical co-morbidities; type of mesh/anatomical route used; onset of symptoms; and time from insertion to removal were recorded.Main Outcome MeasuresDetermination of correlation coefficients between patient demographics, patient reported symptoms and mesh removal surgery.ResultsThree hundred and forty-five women with a history of MAPS were included in the study. Women in the 40–60 year old cohort accounted for 54.4% of mesh removal surgery; 54.8% had a BMI under 30 and almost 90% were Caucasian. 96.5% had had children, with over 77% having had a vaginal delivery. 91.9% of patients reported other health conditions including 18.8% with a concomitant history of mental health problems and 15.4% with a history of heart disease. Over 80% of women undergoing mesh removal surgery had a continence mesh (49% retropubic and 32% obturator continence mesh) removed, whereas 20% had an abdominal prolapse and/or vaginal prolapse mesh removed. The average time from mesh insertion to mesh removal was seven years, with the prevalence of mesh removal surgery averaging 85% (range 50–100%) depending on the comorbidity determined.ConclusionsAll women presented to the clinic with a history of MAPS and other comorbidities which may have influenced their decision to pursue mesh removal surgery. There were no specific predictors, other than chronic pain associated with mesh, determining which women underwent surgery, though those with continence mesh were more likely to do so.

Results of CO2 laser surgery in laryngeal papillomatosis

Recurrent respiratory papillomatosis is medical condition strictly connected with HPV infection of the epithelium of the upper respiratory track. The main treatment of lesions located in larynx or lower pharynx includes microsurgical excision by using CO2 laser. A thorough preoperative assessment of patients is extremely important, which should not only be based on traditional laryngological examination, but also on endoscopy of the larynx and the use of the NBI (narrow band imaging) technique to assess the vascularization of lesions. In patients with recurrent papillomas, neoadjuvant therapy with antiviral agents or agents that inhibit angiogenesis is also often used. Among our group of 31 patients with laryngeal papillomas, 15 people (48%) required repeated surgical intervention and additional antiviral therapy while 10 (33%) people had to undergo the procedure three or more times due to disease recurrence. In this article we will discuss that laryngeal microsurgery with a CO2 laser is an effective method of treating patients with laryngeal papillomatosis and we will present the possibilities of adjuvant therapy.
