Study of non-alcoholic fatty pancreatic disease among the Egyptian population and the value of serum fatty acid binding protein-1 (FABP-1) as a non-invasive biomarker.

BACKGROUND: Non-alcoholic fatty pancreas disease (NAFPD) can be detected using various imaging techniques, but accurately measuring the amount of fat in the pancreas remains difficult. Fatty acid binding protein-1 (FABP-1) is a marker specific to certain tissues and can aid in diagnosing NAFPD. However, this study aimed to investigate the prevalence of NAFPD among obese and non-obese people with and without diabetes mellitus (DM). Additionally, it aimed to evaluate the associated risk factors for NAFPD and the utility of the FABP-1 level as a simple, non-invasive biomarker for diagnosing NAFPD. METHODS: This study is a prospective cross-sectional study. RESULTS: Ninety-five patients were enrolled in the study, comprising 35 males and 60 females, with a mean age of 44 years and a standard deviation (SD) of 11 years. However, 26.3 % were morbidly obese, 22.1 % were severely obese, 31.6 % were obese, 12.6 % were overweight, and 7.4 % were normal. Additionally, 35.8 % had diabetes mellitus, while 26.3 % of patients had hypertension. Regarding the ultrasonographic findings, 94.7 % of the patients had fatty liver, with the majority (41.1 %) classified as grade II, followed by 38.9 % classified as grade I, and 14.7 % classified as grade III fatty liver. Among these patients, 78.9 % had fatty pancreas, with 38.9 % classified as grade II, 31.6 % classified as grade I, and 8.4 % classified as grade III fatty pancreas. The median FABP-1 level among patients with fatty pancreas was 3.3 ng/ml, which exhibited a significant fair negative correlation with total bilirubin and a fair, positive correlation with alkaline phosphatase and portal vein diameter. A statistically substantial distinction was observed between the levels of AFABP-1 and the presence or grading of the fatty pancreas (p-value = 0.048 and < 0.001, respectively). Using multivariate analysis, FABP-1 was the only significant predictor of a fatty pancreas. The receiver operating characteristic (ROC) curve analysis indicated that at a cut-off point of FABP-1 of ≤ 3.7, it had a sensitivity of 58 %, specificity of 80 %, positive predictive value (PPV) of 96.6 %, negative predictive value (NPV) of 17 %, and an area under the curve (AUC) of 0.77. CONCLUSION: NAFPD is becoming an increasingly significant challenge. FABP-1 can potentially be a straightforward and non-invasive predictor of the fatty pancreas.

Beneficial role of healthy eating Index-2015 score & physical activity on COVID-19 outcomes.

BACKGROUND: Nutritional status and physical activity are essential to maintain a strong immune system. No definite pharmacological strategies for Coronavirus disease 2019 treatment are presently available, so natural enhancement of the immune system is in need. Our goal was to assess the correlation of healthy diet and physical activity on COVID-19 disease outcome. METHODS: This cohort study was conducted on 68 adult patients who contracted mild (38) or moderate [30] cases of COVID-19, recruited via a convenience sampling technique from the outpatient clinic, Kasr Al-Aini Faculty of Medicine, Cairo University Hospital. Patients' Healthy Eating Index (HEI) and degree of physical activity as measured by the Global Physical Activity Questionnaire were evaluated and linked with several inflammatory markers. RESULTS: Most of patients with mild COVID-19 patients (92.1%) were physically active, compared to only 50% of moderate COVID-19. The total Metabolic Equivalent Task-min/week was positively correlated with the lymphocyte percentage. The median total HEI score was significantly higher in the patients with mild COVID-19 than with moderate COVID. Significant positive correlations observed among the lymphocyte count and total HEI-2015. There was approximately a 64% reduction in the probability of acquiring moderate COVID-19 illness for each unit rise in The HEI. CONCLUSION: Healthier nutrition and Physical activity correlated with reduced COVID-19 disease severity. TRIAL REGISTRATION: The study was registered on clinical trial.gov maintained by the US National Library of Medicine (CinicalTrials.gov identifier = NCT04447144; https://clinicaltrials.gov/ ) (25/06/2020).

Role of endoscopic ultrasound and endoscopic ultrasound-guided tissue acquisition in diagnosing hepatic focal lesions.

BACKGROUND: Endoscopic ultrasonography (EUS) has become an established method in diagnostic and therapeutic procedures in gastroenterology; however, it has recently gained a growing role in hepatology. AIM: To evaluate the role of EUS features, strain elastography (SE), and EUS-tissue acquisition in diagnosing hepatic focal lesions (HFLs) that could affect further management. METHODS: This cross-sectional study included 215 patients with pancreatic, biliary, or gastrointestinal malignancies referred for EUS examination. HFLs were identified in 43 patients (20%), and EUS-guided tissue acquisition was performed from these lesions. RESULTS: EUS features were highly sensitive (100%) but much less specific (57%) in diagnosing HFLs; the overall accuracy was 94%. Real-time elastography was also very sensitive (97%) but less specific (67%) in diagnosing HFLs; however, the overall accuracy was 92%. EUS tissue acquisition was extremely sensitive (100%) and specific (100%), with a 100% overall diagnostic accuracy. CONCLUSION: The diagnostic utility of EUS-guided tissue acquisition was extremely accurate in diagnosing HFLs. EUS characteristics and real-time SE accurately predicted the histological diagnosis of both benign and malignant HFLs.

Role of endoscopic ultrasound in the characterization of solid pseudopapillary neoplasm of the pancreas.

BACKGROUND: Solid pseudopapillary neoplasm (SPN) is an uncommon pathology of the pancreas with unpredictable malignant potential. Endoscopic ultrasound (EUS) assessment plays a vital role in lesion characterization and confirmation of the tissue diagnosis. However, there is a paucity of data regarding the imaging assessment of these lesions. AIM: To determine the characteristic EUS features of SPN and define its role in preoperative assessment. METHODS: This was an international, multicenter, retrospective, observational study of prospective cohorts from 7 large hepatopancreaticobiliary centers. All cases with postoperative histology of SPN were included in the study. Data collected included clinical, biochemical, histological and EUS characteristics. RESULTS: One hundred and six patients with the diagnosis of SPN were included. The mean age was 26 years (range 9 to 70 years), with female predominance (89.6%). The most frequent clinical presentation was abdominal pain (80/106; 75.5%). The mean diameter of the lesion was 53.7 mm (range 15 to 130 mm), with the slight predominant location in the head of the pancreas (44/106; 41.5%). The majority of lesions presented with solid imaging features (59/106; 55.7%) although 33.0% (35/106) had mixed solid/cystic characteristics and 11.3% (12/106) had cystic morphology. Calcification was observed in only 4 (3.8%) cases. Main pancreatic duct dilation was uncommon, evident in only 2 cases (1.9%), whilst common bile duct dilation was observed in 5 (11.3%) cases. One patient demonstrated a double duct sign at presentation. Elastography and Doppler evaluation demonstrated inconsistent appearances with no emergence of a predictable pattern. EUS guided biopsy was performed using three different types of needles: Fine needle aspiration (67/106; 63.2%), fine needle biopsy (37/106; 34.9%), and Sonar Trucut (2/106; 1.9%). The diagnosis was conclusive in 103 (97.2%) cases. Ninety-seven patients were treated surgically (91.5%) and the post-surgical SPN diagnosis was confirmed in all cases. During the 2-year follow-up period, no recurrence was observed. CONCLUSION: SPN presented primarily as a solid lesion on endosonographic assessment. The lesion tended to be located in the head or body of the pancreas. There was no consistent characteristic pattern apparent on either elastography or Doppler assessment. Similarly SPN did not frequently cause stricture of the pancreatic duct or common bile duct. Importantly, we confirmed that EUS-guided biopsy was an efficient and safe diagnostic tool. The needle type used does not appear to have a significant impact on the diagnostic yield. Overall SPN remains a challenging diagnosis based on EUS imaging with no pathognomonic features. EUS guided biopsy remains the gold standard in establishing the diagnosis.

Treatment results of Para-Testicular Rhabdomyosarcoma (PT-RMS) using radiation as an alternative to retro-peritoneal nodal dissection: A single Institution experience.

BACKGROUND: Para-testicular Rhabdomyosarcoma (PT-RMS) has a favorable treatment outcome adopting multidisciplinary management; resection, namely high inguinal orchiectomy ± retro-peritoneal lymph node dissection (RPLND) followed by standard or intensive chemotherapy ± adjuvant radiation therapy. PATIENTS AND METHODS: This is a retrospective study including all patients with pathologically proven PT-RMS, presented to the National Cancer Institute, Cairo University, during the period from 2005 to 2020. Endpoints included overall survival, disease free survival and patterns of failure of different treatment modalities. RESULTS: Forty one patients were identified. Median age in our cohort was 15 years (range: 2-54 years). After a median follow up of 26 months (range, 3-75 months) ,two and five years OS were 100% and 91.7% respectively and median survival was not reached. Patients who underwent retro-peritoneal nodal dissection had a 5-year DFS rate of 100% versus 73% for those who received radiation to para-aortic nodes (p = 0.185). Limitations include retrospective nature and deviation from COG protocol. CONCLUSIONS: This study shows promising results suggesting that less aggressive local treatment modalities including radiation to para-aortic chain could be an option in PT-RMS, given the excellent results of this subtype. However further validation in a prospective study is warranted.

Beyond probiotic legend: ESSAP gut microbiota health score to delineate SARS-COV-2 infection severity.

COVID-19 pandemic continues to be a global health crisis. The gut microbiome critically affects the immune system, and some respiratory infections are associated with changes in the gut microbiome; here, we evaluated the role of nutritional and lifestyle habits that modulate gut microbiota on COVID-19 outcomes in a longitudinal cohort study that included 200 patients infected with COVID-19. Of these, 122 cases were mild and seventy-eight were moderate, according to WHO classification. After detailed explanation by a consultant in clinical nutrition, participants responded to a written questionnaire on daily sugar, prebiotic intake in food, sleeping hours, exercise duration and antibiotic prescription, during the past 1 year before infection. Daily consumption of prebiotic-containing foods, less sugar, regular exercise, adequate sleep and fewer antibiotic prescriptions led to a milder disease and rapid virus clearance. Additionally, data on these factors were compiled into a single score, the ESSAP score (Exercise, Sugar consumption, Sleeping hours, Antibiotics taken, and Prebiotics consumption; 0-11 points), median ESSAP score was 5 for both mild and moderate cases; however, the range was 4-8 in mild cases, but 1-6 in moderate (P = 0·001, OR: 4·2, 95 % CI 1·9, 9·1); our results showed a negative correlation between regular consumption of yogurt containing probiotics and disease severity (P = 0·007, OR: 1·6, 95 % CI 1·1, 2·1). Mild COVID-19 disease was associated with 10-20 min of daily exercise (P = 0·016), sleeping at least 8 h daily, prescribed antibiotics less than 5 times per year (P = 0·077) and ate plenty of prebiotic-containing food.

Role of EUS in detection of liver metastasis not seen by computed tomography or magnetic resonance imaging during staging of pancreatic, gastrointestinal, and thoracic malignancies.

BACKGROUND AND OBJECTIVES: Liver metastases might not be detected by computed tomography (CT) and magnetic resonance imaging (MRI) due to their small size, but they can be detected by EUS. Furthermore, EUS-FNA has a significant impact on improving the diagnostic accuracy of EUS. The purpose of this study was to assess the feasibility of EUS in detection of occult small hepatic focal lesions at the time of primary tumor staging, not seen by CT or MRI. METHODS: This prospective study included 730 patients who underwent EUS for staging or sampling of gastrointestinal, pancreatic, or thoracic malignancy. The liver was examined thoroughly for detection of occult lesions. CT or MRI was done within 1 week of EUS examination. RESULTS: EUS examination of the liver detected focal lesions in 150 patients (20.5%) and metastases in 118 patients (16.2%); meanwhile, CT and MRI detected focal lesions in 99 patients (13.6%) and metastases in 82 patients (11.2%). EUS missed focal lesions in 7 patients, 6 of which were liver metastases (1.0% and 0.8%, respectively), while CT and MRI missed focal lesions in 58 patients, 42 of which were metastases (7.9% and 5.8%, respectively), which were detected by EUS. CONCLUSION: Thorough dedicated EUS examination of the liver is a feasible useful tool for detection of small hepatic lesions missed by CT and MRI. It is not considered an extra financial burden to the patient or health-care system because those patients are indicated for EUS examination for evaluation of their original lesion in the first place. Furthermore, EUS-FNA can add another advantage in diagnosing the etiology of such lesions.

COVID-19 Disease Outcomes: Does Gastrointestinal Burden Play a Role?

BACKGROUND: The novel coronavirus disease 2019 presents an urgent threat to global health. As the epidemic grows, prognosis prediction is essential for monitoring risky patient. It is thus important to consider gastrointestinal manifestations and the duration of symptoms as predictors of prognosis. Our aim was to determine the correlation of gastrointestinal symptoms and laboratory markers with disease outcomes and whether symptom duration varies substantially between patients. We also undertook this study to determine the optimal time to predict COVID-19 outcome. PATIENTS AND METHODS: A total of 190 patients with polymerase chain reaction-confirmed COVID-19 were followed up until recovery. We proposed a correlation between gastrointestinal symptoms and disease severity (based on clinical data, and diagnostic investigations) to estimate the duration of symptoms as a predictor of COVID-19 prognosis. RESULTS: The prevalence of gastrointestinal symptoms was 49.5%, consisting mainly of diarrhea in 27.9% of patients. In addition, a longer disease duration and higher temperature were observed in patients with diarrhea. Symptom duration was variable, with a median of 12 days and a range of 1-55 days. Statistical analysis indicated that patients with a duration of symptoms ≥12 day had more severe symptoms and a worse prognosis. Patients who complained of diarrhea had 2.7 times the odds of a longer duration of symptoms, and those with a history of chronic lung disease have 7.2 times the odds of a longer duration of symptoms. CONCLUSION: GIT manifestations (mainly diarrhea) and the duration of symptoms of COVID-19 provide prognostic evidence of COVID-19 outcomes, irrespective of earlier categorization by the World Health Organization. Thus, patients with mild symptoms who present with diarrhea and a duration of symptoms longer than 12 days are expected to have a worse prognosis.
