Feasibility, safety and effectiveness of the enhanced recovery after surgery protocol in patients undergoing liver resection.

Backgrounds/Aims: The implementation of enhanced recovery after surgery (ERAS) protocols has demonstrated significant advantages for patients by mitigating surgical stress and expediting recovery across a spectrum of surgical procedures worldwide. This investigation seeks to assess the effectiveness of the ERAS protocol specifically in the context of major liver resections within our geographical region. Methods: Our department conducted retrospective analysis of prospectively collected data, gathered from consenting individuals who underwent liver resections from January 2018 to December 2023. The assessment encompassed baseline characteristics, preoperative indications, surgical outcomes, and postoperative complications among patients undergoing liver surgery. Results: Among the included 184 patients (73 standard care, 111 ERAS program), the baseline characteristics were similar. Median postoperative hospital stay differed significantly: 5 days (range: 3-13 days) in ERAS, and 11 days (range: 6-22 days) in standard care (p < 0.001). Prophylactic abdominal drainage was less in ERAS (54.9%) than in standard care (86.3%, p < 0.001). Notably, in ERAS, 88.2% initiated enteral feeding orally on postoperative day 1, significantly higher than in standard care (47.9%, p < 0.001). Early postoperative mobilization was more common in ERAS (84.6%) than in standard care (36.9%, p < 0.001). Overall complication rates were 21.9% in standard care, and 8.1% in ERAS (p = 0.004). Conclusions: Our investigation highlights the merits of ERAS protocol; adherence to its diverse components results in significant reduction in hospital length of stay, and reduced occurrence of postoperative complications, improving short-term recovery post liver resection.

Glucagon-like peptide-1 analogues in monogenic syndromic obesity: Real-world data from a large cohort of Alström syndrome patients.

AIM: To examine the real-world efficacy of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in monogenic obesity in patients with Alström syndrome (ALMS). METHODS: We screened 72 UK adult patients with ALMS and offered treatment to 34 patients meeting one of the following criteria: body mass index of 25 kg/m2 or higher, insulin resistance, suboptimal glycaemic control on antihyperglycaemic medications or non-alcoholic fatty liver disease. RESULTS: In total, 30 patients, with a mean age of 31 ± 11 years and a male to-female ratio of 2:1, completed 6 months of treatment with GLP-1 RAs either in the form of semaglutide or exenatide. On average, treatment with GLP-1 RAs reduced body weight by 5.4 ± 1.7 (95% confidence interval [CI] 3.6-7) kg and HbA1c by 12 ± 3.3 (95% CI 8.7-15.3) mmol/mol, equating to 6% weight loss (P < .01) and 1.1% absolute reduction in HbA1c (P < .01). Significant improvements were also observed in serum total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and alanine aminotransferase. The improvement of metabolic variables in our cohort of monogenic syndromic obesity was comparable with data for polygenic obesity, irrespective of weight loss. CONCLUSIONS: Data from our centre highlight the non-inferiority of GLP-1 RAs in monogenic syndromic obesity to the available GLP-1 RA-use data in polygenic obesity, therefore, these agents can be considered as a treatment option in patients with ALMS, as well as other forms of monogenic obesity.

Adipose tissue function and insulin sensitivity in syndromic obesity of Bardet-Biedl syndrome.

BACKGROUND: Bardet-Biedl syndrome (BBS) is a rare autosomal recessive syndromic obesity of childhood onset among many other features. To date, the excess risk of metabolic complications of severe early-onset obesity in BBS remains controversial. In-depth investigation of adipose tissue structure and function with detailed metabolic phenotype has not been investigated yet. OBJECTIVE: To investigate adipose tissue function in BBS. DESIGN: A prospective cross-sectional study. MAIN OUTCOME MEASURE: To determine if there are differences in insulin resistance, metabolic profile, adipose tissue function and gene expression in patients with BBS compared to BMI-matched polygenic obese controls. METHOD: 9 adults with BBS and 10 controls were recruited from the national centre for BBS, Birmingham, UK. An in-depth study of adipose tissue structure and function along with insulin sensitivity was performed using hyperinsulinemic-euglycemic clamp studies, adipose tissue microdialysis, histology and RNA sequencing, and measurement of circulating adipokines and inflammatory biomarkers. RESULTS: Adipose tissue structure, gene expression and in vivo functional analysis between BBS and polygenic obesity cohorts were similar. Using hyperinsulinemic-euglycemic clamp and surrogate markers of insulin resistance, we found no significant differences in insulin sensitivity between BBS and obese controls. Furthermore, no significant changes were noted in an array of adipokines, cytokines, pro-inflammatory markers and adipose tissue RNA transcriptomic. CONCLUSION: Although childhood-onset extreme obesity is a feature of BBS, detailed studies of insulin sensitivity and adipose tissue structure and function are similar to common polygenic obesity. This study adds to the literature by suggesting that it is the quality and quantity of adiposity not the duration that drives the metabolic phenotype.

Protein Convertase Subtilisin/Kexin Type 9 Monoclonal Antibodies (PCSK9mab) in Clinical Practice at Secondary Care - Real World Multicentre Experience.

Background and Aims Protein convertase subtilisin/Kexin type 9 monoclonal antibodies (PCSK9mab) are a novel addition to the therapeutic options for managing hyperlipidemia. Various guidelines have advocated the addition of these agents if the target low-density lipoprotein-cholesterol ( LDL-C) is not achieved by maximum lipid-lowering therapy. They have shown a robust and consistent reduction in LDL-C in clinical trials. However, the translation of these results in a real-world setting is limited and confined mainly to tertiary lipid centers. This service evaluation aimed to assess their efficacy in a real-world outpatient setting of secondary care centers. Methods Data was collected retrospectively from four hospitals in the North-West of England. Patients were required to attend a lipid clinic for follow-up investigations to continue with the prescription of PCSK9mab. Results A total of 175 patients were identified. Efficacy outcomes were measured in 169 patients. 6 discontinued the agent within 3 months of initiation and were excluded from the efficacy outcomes. 19.5% (n=33) had confirmed familial hypercholesterolemia. 61% (n=103) of the patients were intolerant to statins. 53.2% (n=90) of the patients have been prescribed Alirocumab. Mean LDL-C reduction was 50.6% at 6-month which was sustained at 48.9% at 12 months. There was no difference in % reduction of LDL-C between Alirocumab and Evolocumab. LDL-C reduction was more significant in patients who were on concomitant statins. 9.1% of patients experienced side effects, and 5.1% discontinued the PCSK9mab during treatment. Conclusion The efficacy of lipid reduction and the side effect profile of PCSK9mab from these secondary care services are similar to randomized clinical trials and real-world observational studies from tertiary lipid centers.

Trifascicular Block and Ventricular Standstill: A Late Complication of Mediastinal Radiotherapy in a Cancer Survivor.

Over the last half-century, radiation therapy has evolved to become one of the cornerstones of treatment for various types of cancers. It is estimated that more than 50% of patients with cancer are treated with radiotherapy. Patients with early stages of some cancers can even achieve a cure with radiotherapy alone. Radiation-induced heart disease is a well-recognized cause of mortality and morbidity in cancer survivors as a late complication of radiotherapy, often occurring more than a decade after radiotherapy. We describe a case of a middle-aged female who presented to the hospital with syncopal episodes. She was in remission from non-Hodgkin's lymphoma having received mediastinal radiotherapy 20 years, previously. Her initial workup such as laboratory investigations and 12 lead electrocardiogram were largely unremarkable. Cardiac monitoring over the course of the next few days was consistent with complete heart block with evidence of ventricular standstill. Her symptoms resolved following the implantation of a dual-chamber cardiac pacemaker. This case highlights the significance of clinical history taking and putting together all relevant facts to come to a differential diagnosis. In our case, this could have been easily overlooked as radiation therapy was given many years previously. We review and present an up-to-date albeit brief literature review on long-term cardiovascular complications of radiotherapy. Radiation-induced cardiac complications are an important cause of mortality and morbidity in cancer survivors. This article aims to raise awareness amongst clinicians of cardiac adverse effects occurring several years after the radiation therapy. This case also highlights the need for further research to better understand the pathophysiology of cardiovascular disease post-radiotherapy in order to develop effective prevention strategies and improve clinical outcomes.

Impact of Coronavirus disease (COVID-19) pandemic on health professionals.

OBJECTIVE: Recognizing the huge potential ramifications of COVID-19 pandemic, this study explores its impact on health professionals personally and professionally along with the associated challenges. METHODS: A descriptive cross-sectional qualitative survey was conducted from March-April 2020. Participants included health professionals from various disciplines in both public and private-sector institutions of Pakistan. The sample size was not predetermined, and an iterative approach of simultaneous data collection and analysis was taken until data and time saturation were reached. Thematic analysis of the qualitative data was carried out by two analysts. RESULTS: Two hundred and Ninety health professionals responded. They reported an impact on their mental, physical and social well-being. The clinicians mentioned facing an unprecedented workload in overstretched health facilities, while those in academia become engaged with planning/providing emergency remote teaching for the students affecting work-life balance. Some challenges associated with work-from-home and in the hospitals were identified. CONCLUSION: During COVID-19, the health professionals are anxious, overworked and financially unstable while planning, creating and caring for others and their families. We need to support them to do their jobs, be safe and stay alive. Future research should explore the fears and coping strategies of health professionals during pandemics.

Acute cor pulmonale from saddle pulmonary embolism in a patient with previous COVID-19: should we prolong prophylactic anticoagulation?

Severe coronavirus disease 2019 (COVID-19) is known to be associated with a heightened risk of thromboembolism. However, the risk associated with mild and moderate illness from COVID-19 is unknown, and there is no current recommendation for prophylaxis against thromboembolism in patients after hospital treatment, unless there are established thrombophilic risk factors. We report the case of a 52-year-old woman who presented with massive saddle pulmonary embolism 1 week after initial hospital discharge, which was treated successfully with thrombolysis. This case raises the question of whether extended prophylactic anticoagulation should be considered even in low-risk COVID-19 cases.

Association of Helicobacter pylori with hepatobiliary stone disease, a prospective case control study.

BACKGROUND: Hepatobiliary stone disease is one of the most common surgical conditions worldwide. There are multiple causative agents responsible for the formation of hepatobiliary stones, and bacterial infection is one of them. The presence of Helicobacter DNA species has been investigated in the biliary epithelium of patients with biliary diseases. However, conflicting results have been observed that may have been due to the small number of subjects studied, difficulty in obtaining a healthy control group, absence of controlling for confounding factors, or ethical and regional differences among populations. METHODS: We investigated the presence of Helicobacter pylori species by PCR of 26-kDa surface antigen specific to H. pylori in bile samples from 50 cases with hepatobiliary stones and 25 controls without hepatobiliary stones. The control group comprised of 20 patients of hydatid cyst disease of liver and 5 patients of right colonic growth. RESULT: H. pylori was present in 20 bile samples among cases and was absent in 30 bile samples among cases. Among controls, H. pylori could not be detected. A significant association of the presence of H. pylori with hepatobiliary stone disease was seen (p < 0.001). CONCLUSION: There is an association between bile infection with H. pylori and hepatobiliary stone disease.

Giant mucinous cystadenoma: case report with review of literature.

Cystic tumors of the pancreas are rare and can be confused with hydatid cyst especially in endemic areas like ours. We present a 30-year-old woman with a huge mucinous cystadenoma of the pancreas initially diagnosed and prepared on table as hydatid cyst. After incising the cyst the diagnosis of cystic tumor was considered and underwent total excision with spleen and healthy pancreatic margin. Histologically and biochemistry of fluid confirmed potentially benign mucinous cystic tumor of pancreas tumor excision after histological diagnosis. Sensitivity of radiological imaging values in differentiating between cystic pancreatic tumors and other limited. Cyst wall histology is diagnostic and biopsy of cyst wall should be done in cases with inconclusive preoperative diagnosis or questionable operative findings.

64-section multiphase CT enterography as a diagnostic tool in the evaluation of obscure gastrointestinal bleeding.

BACKGROUND AND AIM: Small bowel follow through (SBFT) and enteroclysis have low sensitivity in picking up lesions in obscure gastrointestinal bleed (OGIB). Computed tomographic enterography (CT-EG), performed with 64-slice multiphase CT system by using large volumes of ingested neutral enteric contrast material, has high spatial and temporal resolution in visualization of the small bowel wall and lumen. The role of 64-slice multiphase CT-EG in the evaluation of OGIB is still evolving, and data on this role are scarce. We evaluated the efficacy of 64-slice multiphase CT-EG using polyethylene glycol (PEG) electrolyte solution as neutral contrast in patients of OGIB. METHODS: CT-EG was performed with 64-slice multiphase CT system using large volume (2,000 mL) of PEG electrolyte solution as oral contrast in patients of OGIB. RESULTS: Thirty-five patients (21 men, age 41.4 [13.5] y, range 19-70 year) with OGIB underwent CT-EG; 20 patients had overt OGIB whereas 15 patients had occult OGIB. Among 15 patients with occult OGIB, 10 patients had iron deficiency anemia (IDA) with fecal occult blood test (FOBT) positive and 5 had IDA with FOBT negative. Thirty-two patients (92 %) completed the procedure successfully. The total time taken for the ingestion of 2,000 mL of PEG electrolyte solution was median 64 (range 60-78) minutes. Adequate luminal distension of small bowel was seen in 29 (90.6 %) patients for successful interpretation of radiological images. Fifteen of 32 (46.9 %) patients had positive findings on CT-EG; 12 of them underwent exploratory laparotomy. The surgical findings were in conformity with CT-EG findings in all patients, which included gastrointestinal stromal tumors (GIST; n = 6), carcinoid (1), Meckel's diverticulum (1), small bowel adenocarcinoma (2) and jejunal vascular malformation (2). CONCLUSION: 64-slice multiphase CT-EG is a useful investigation in the evaluation of both occult and overt OGIB.

Giant splenic artery aneurysm: case report.

Splenic artery aneurysm is the third most common location of intra-abdominal aneurysms. Giant splenic artery aneurysm is rarely seen and is at a high risk of rupture. Location and size of the splenic artery aneurysm determine the likelihood of rupture. A case of giant splenic artery aneurysm in a 35-year-old woman is reported. She presented with upper gastrointestinal bleeding. She had splenomegaly and extrahepatic hepatic portal hypertension. Angiography confirmed a giant splenic artery aneurysm measuring 8 × 10 centimeters, located in middle and distal two-thirds of the splenic artery. Surgical treatment in the form of in toto excision of aneurysm with splenectomy and devascularization was performed.

Hydatid cyst of the pancreas. An experience with six cases.

CONTEXT: The pancreas is an infrequent site of hydatid disease. OBJECTIVE: This study aims at giving better insight into the diagnostic and managerial approach to the disease. PATIENTS: Six patients with hydatid cysts of the pancreas. DESIGN: Retrospective review of the clinical records. RESULTS: The six patients (four men, two women) ranged in age from 18 to 68 years. Five of the cysts were primary while one had an associated cyst in the liver. Abdominal pain, vomiting, abdominal mass and dyspeptic symptoms were seen in cysts involving the body and tail. Two patients having cysts in the head of the pancreas presented with obstructive jaundice. An indirect hemagglutination test and an enzyme-linked immunoabsorbent assay were positive for the presence of specific hydatid antibodies in four patients. Abdominal ultrasonography, computed tomography and magnetic resonance cholangiopancreatography (MRCP) successfully imaged the cysts and also defined the relationship of the lesion with the pancreatic duct. All patients underwent surgical exploration. Three patients had intraoperative fine needle aspiration cytology of the cystic lesion for microscopic and electrolyte analysis. A preoperative diagnosis was possible in two patients and, in the other four, the diagnosis was made intraoperatively and confirmed on histopathological examination. PATIENTS: with cysts located in the tail underwent a distal pancreatectomy with a splenectomy while those with cysts in the body had a pericystectomy or central pancreatectomy. Cysts of the head were treated with evacuation, partial cystectomy and tube drainage. There were no postoperative complications, and no evidence of cyst recurrence was observed during the follow-up period. All the patients were followed up at three-month intervals with a mean follow-up time of 58.7 months (rang: 4-120 months); no patient had cyst recurrence or dissemination. CONCLUSION: A hydatid cyst is an uncommon cause of cystic lesions in the pancreas and should be included in the differential diagnosis of cystic lesions of the pancreas, especially in endemic areas. Intraoperative fine needle aspirate for microscopic and electrolyte estimation seems to be an effective method for establishing a proper diagnosis. MRCP, which can depict the communication of the cystic lesion with the pancreatic duct, helps in defining the type of surgical treatment. Cysts in body and tail are best treated by resectional methods whereas, for those in the head region, a cystectomy with simple drainage is a simple, quick and effective solution.

Glucocorticoid-mediated inhibition of angiogenic changes in human endothelial cells is not caused by reductions in cell proliferation or migration.

BACKGROUND: Glucocorticoid-mediated inhibition of angiogenesis is important in physiology, pathophysiology and therapy. However, the mechanisms through which glucocorticoids inhibit growth of new blood vessels have not been established. This study addresses the hypothesis that physiological levels of glucocorticoids inhibit angiogenesis by directly preventing tube formation by endothelial cells. METHODOLOGY/PRINCIPAL FINDINGS: Cultured human umbilical vein (HUVEC) and aortic (HAoEC) endothelial cells were used to determine the influence of glucocorticoids on tube-like structure (TLS) formation, and on cellular proliferation (5-bromo-2'-deoxyuridine (BrdU) incorporation), viability (ATP production) and migration (Boyden chambers). Dexamethasone or cortisol (at physiological concentrations) inhibited both basal and prostaglandin F(2α) (PGF(2α))-induced and vascular endothelial growth factor (VEGF) stimulated TLS formation in endothelial cells (ECs) cultured on Matrigel, effects which were blocked with the glucocorticoid receptor antagonist RU38486. Glucocorticoids had no effect on EC viability, migration or proliferation. Time-lapse imaging showed that cortisol blocked VEGF-stimulated cytoskeletal reorganisation and initialisation of tube formation. Real time PCR suggested that increased expression of thrombospodin-1 contributed to glucocorticoid-mediated inhibition of TLS formation. CONCLUSIONS/SIGNIFICANCE: We conclude that glucocorticoids interact directly with glucocorticoid receptors on vascular ECs to inhibit TLS formation. This action, which was conserved in ECs from two distinct vascular territories, was due to alterations in cell morphology rather than inhibition of EC viability, migration or proliferation and may be mediated in part by induction of thrombospodin-1. These findings provide important insights into the anti-angiogenic action of endogenous glucocorticoids in health and disease.

Primary fibrosarcoma of the liver: we don't know much: a case report.

A 60-year-old lady presented to us with a right upper abdominal mass. With a clinical diagnosis of liver tumor, she was evaluated with abdominal CT, MRI, nuclear scan, tumor markers, USG guided FNAC and other baseline investigations. On evaluation she had a massive right lobe tumor crossing the midline. In view of the ambiguous diagnosis she was subjected to laparotomy where the lesion was judged unresectable and a biopsy was taken. Histopathological examination showed the rare pathology of primary fibrosarcoma of the liver with features of homogeneous, spindle-shaped cells with abundant collagen fibers showing a classic herringbone pattern. Tissue samples were then sent to another referral cancer hospital for immunohistochemistry and immunoreactive vimentin was found in the tumor cells. Electron microscopically, the tumor cells were rich in rough endoplasmic reticulum without a basement membrane, and were surrounded by large amounts of collagen fibers. The fibroblastic character of the tumor cells was suggested by light and electron microscopy.
