25). Furthermore, multiple light scattering analysis confirmed NLG improved colloidal stability in phosphate buffer saline and cell culture medium, with respect to NG. Finally, lipid coating completely abrogated the cytotoxicity of NG when incubated at 50 μg·mL-1 with HeLa, U87, or b.End3 cell lines and significantly improved the biocompatibility at 100 and 150 μg·mL-1. Future investigations will explore how the lipid coating affects drug loading, release profile, and the ability of NLG to deliver drugs and genes in vitro.
In spite of advances in surgical techniques, the significance of anastomosis leak continues in colorectal surgery. There is no ideal method in spite of all studies and technical advances in this field. Our aim ofthis study was to use fibroblast growth factor collagen (FGF-C) and antibiotic collagen (AB-C) to increase the rate of anastomosis healing in experimental animals withperitonitis.

This animal experimental study received ethics committee approval. Theanimals were dividedinto three groupsof seven animalseach; the first group was control, the second group was the fibroblast growth factor collagen group, and the third group was the antibiotic collagen group. Under anesthesia, more than 50% of the colonic lumen was opened 4-5cm distal tothe ileocecal junction to create a defect. Twenty-four hours later, primary anastomosis was performed. The second group had the anastomosis line covered with a cover containing FGF-C. The third group had the anastomosis line covered by material containing AB-C. The experiment was concluded on the postoperative 7th day, and the anastomosis burst pressure, tissue hydroxyproline level, and histopathological assessment were performed.

Though the burst pressure was higher in the experimental groups, it was not statistically significant. In the second and third groups, vascular proliferation and fibroblastic activity appeared to be better than in the control group. Hydroxyproline values were statistically significant in the experimental groups compared to the control group.

FGF-C and AB-C may have potential utility in anastomosis healing, especially in those susceptible to infection due to anastomosis leak.

Living donor liver transplant (LDLT) for hepatocellular carcinoma (HCC) has been controversial in terms of selection and outcome. We share our experience of LDLT for HCC in Indian patients.

Retrospective analysis of patients undergoing LDLT for HCC discovered either preoperatively or incidentally on explant pathology was done. Preoperative characteristics and explant histopathology findings were recorded. Overall, recurrence-free survival and factors predicting recurrence were analyzed.

Six hundred and eleven LDLT were performed between June 2011 and October 2019. HCC constituted 6.5% (n = 53) of transplant activity. Forty had preoperative diagnosis, while 13 were detected incidentally. The median model for end-stage liver disease (MELD) score was 18 for patients with HCC. Only in 10 patients (19%), HCC was the primary indication for liver transplant (LT), and the rest had undergone transplant for progressive decompensation. Thirty-two patients were within up-to-7, while 21 were outside up-to-7 criteria. Overall 5-year survival was 85.4% and recurrence-free survival was 83.3% after a median follow-up of 35months (13-59). This was similar to LDLT for other indications (81.2% at 5years). Risk Estimation of Tumor Recurrence After Transplant (RETREAT) score was best able to predict recurrence (p = 0.03) with odds ratio of 6.8.

Patients with HCC in India present late for liver transplant. Most patients have some form of decompensation before they undergo LT. In selected patients, overall survival was comparable with other indications for LDLT with acceptable recurrence rates. RETREAT score was best to predict recurrence.

Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) in acute pancreatitis (AP) are associated with development and worsening of organ failures and poor prognosis. Limited studies suggest that contrast-enhanced computed tomography(CECT) can predict the presence of IAH/ACS.We aimedto study clinical profile of patients with AP and IAH and identify predictive factors of IAH on CECT abdomen.

Consecutive patients admitted with moderately severe and severe acute pancreatitis (SAP) were recruited. Clinical and radiological data were recorded prospectively. Intra-abdominal pressure was measured via a urinary catheter to document the presence of IAH/ACS. CECT abdomen was done within the first week of admission and various features that may predict the presence of IAH were studied.

Thirty-seven patients (24 SAP) (mean age 39.78 ± 13.43years and 67.6% males) with APwere studied. The most common etiology was alcohol (37.7%). IAH developed in 54.05% of patients; patients with IAH had significapatients.Cardiopulmonary arrest (CA) can greatly impact a patient's life, causing long-term disability and death. Although multi-faceted treatment strategies against CA have improved survival rates, the prognosis of CA remains poor. We previously reported asphyxial cardiac arrest (ACA) can cause excessive activation of the sympathetic nervous system (SNS) in the brain, which contributes to cerebral blood flow (CBF) derangements such as hypoperfusion and, consequently, neurological deficits. Here, we report excessive activation of the SNS can cause enhanced neuropeptide Y levels. In fact, mRNA and protein levels of neuropeptide Y (NPY, a 36-amino acid neuropeptide) in the hippocampus were elevated after ACA-induced SNS activation, resulting in a reduced blood supply to the brain. Post-treatment with peptide YY3-36 (PYY3-36), a pre-synaptic NPY2 receptor agonist, after ACA inhibited NPY release and restored brain circulation. Moreover, PYY3-36 decreased neuroinflammatory cytokines, alleviated mitochondrial dysfunction, and improved neuronal survival and neurological outcomes. Overall, NPY is detrimental during/after ACA, but attenuation of NPY release via PYY3-36 affords neuroprotection. The consequences of PYY3-36 inhibit ACA-induced 1) hypoperfusion, 2) neuroinflammation, 3) mitochondrial dysfunction, 4) neuronal cell death, and 5) neurological deficits. The present study provides novel insights to further our understanding of NPY's role in ischemic brain injury.
Gastric cancer is endemic in the so-called stomach cancer region comprising Rwanda, Burundi, South Western Uganda, and eastern Kivu province of Democratic Republic of Congo, but its outcomes in that region are under investigated. The purpose of this study was to describe the short-term outcomes (in-hospital mortality rate, length of hospital stay, 3-, 6-, 12-, and 24-month survival rates) in patients treated for gastric cancer in Rwanda.

We retrospectively reviewed the data collected from records of patients who consulted Kigali University Teaching Hospital (CHUK) over a period of 10years from September 2007 to August 2016. We followed patients before and after discharge for survival data. Baseline demographic data studied using descriptive statistics, whereas Kaplan-Meier model and univariate Cox regression were used for survival analysis.

Among 199 patients enrolled in this study, 92 (46%) were males and 107 (54%) females. The age was ranging between 24 and 93years with a mean age of 55.4. The mean symptom duration was 15months. Many patients had advanced disease, 62.3% with distant metastases on presentation. Treatment with curative intent was offered for only 19.9% of patients. The in-hospital mortality rate was 13.3%. The 3-, 6-, 12-, and 24-month survival rate was 52%, 40.5%, 28%, and 23.4%, respectively. The overall survival rate was 7months.

Rwanda records a high number of delayed consultations and advanced disease at the time of presentation in patients with gastric cancer. This cancer is associated with poor outcomes as evidenced by high hospital mortality rates and short post discharge survival.

We report here a patient with an aggressive well-differentiated high-grade gastric neuroendocrine tumour (gastric grade 3 NET), in a context of autoimmune gastritis. Consistent with grade 3 disease, the tumour had a Ki-67 proliferation index of 30%. Targeted next-generation sequencing identified variants of four genes, including a pathogenic ATM variant underlying the differentiation and metastatic potential of the tumour. Liver metastasis was diagnosed during follow-up, and the patient died after 6 years, due to disease progression.Tumors with papillary cribriform and morular architecture were initially considered to be variants of papillary thyroid carcinoma; however, recent observations have challenged this view. In this study, we reviewed the demographical, histopathological, and immunohistochemical features of the largest case series, consisting of 33 tumors. The age at time of pathological diagnosis ranged from 18 to 59 (mean 33) years, and all patients except one were female. Sixteen patients had multifocal and fifteen had unifocal disease. The status of focality was unavailable in two patients. Tumors were well-circumscribed, ranging in size from 0.1 to 8.0 cm. The cribriform component was admixed with morulae in the majority, except seven had a cribriform-predominant architecture and two had predominantly solid growth. Variable degrees of nuclear enlargement, elongation, overlapping, and grooves were seen but florid nuclear convolution, intranuclear pseudoinclusions, and optically clear nuclei due to chromatin margination were nfferentiation. Given their unique cytomorphology, immunohistochemical profiles, and genetic features that have little overlap with traditional follicular cell-derived thyroid carcinomas, we propose that these tumors represent a distinct form of thyroid carcinoma unrelated to other neoplasms of thyroid follicular cells.
An increased prevalence of vertebral fractures (VFs) has been reported in previous studies. The aim of this study was to evaluate the association between bone mineral density (BMD), bone turnover markers, serum sclerostin levels, and vertebral fractures (VFs) in acromegaly patients. We also evaluated the effects of gonadal status, disease activity, treatment modality, age, sex, and body mass index (BMI) on skeletal endpoints.

Case-control study.

Seventy acromegaly patients (M/F36/34, mean age 45.5 ± 11.9 years) and 70 controls (M/F31/39; mean age 45.66 ± 11.9 years) were included. VFs, BMD, calcium metabolism, markers of bone turnover, and sclerostin levels were evaluated. BMD was measured by dual-energy X-ray absorptiometry (Hologic QDR 4500). Conventional lateral radiography of the spine was performed and the Genant method was used for the assessment of fractures of T4-L5 vertebrae.

The prevalence of vertebral fractures was higher in acromegalic patients as compared with the control group (72.9 vs. 20%; p < 0.
