ITC-Net-blend-60: a comprehensive dataset for robust network traffic classification in diverse environments.

OBJECTIVES: Recognition of mobile applications within encrypted network traffic holds considerable effects across multiple domains, encompassing network administration, security, and digital marketing. The creation of network traffic classifiers capable of adjusting to dynamic and unforeseeable real-world settings presents a tremendous challenge. Presently available datasets exclusively encompass traffic data obtained from a singular network environment, thereby restricting their utility in evaluating the robustness and compatibility of a given model. DATA DESCRIPTION: This dataset was gathered from 60 popular Android applications in five different network scenarios, with the intention of overcoming the limitations of previous datasets. The scenarios were the same in the applications set but differed in terms of Internet service provider (ISP), geographic location, device, application version, and individual users. The traffic was generated through real human interactions on physical devices for 3-15 min. The method used to capture the traffic did not require root privileges on mobile phones and filtered out any background traffic. In total, the collected dataset comprises over 48 million packets, 450K bidirectional flows, and 36 GB of data.

COVID-19 Outbreak and its Burden on a New Wave of Functional Gastrointestinal Disorders.

The current outbreak of COVID-19 infection among humans is strongly impacting global physical and mental health. This outbreak can induce or exacerbate some chronic disorders such as functional gastrointestinal disorders (FGIDs) due to stress, anxiety, depression, insomnia, denial, anger, and fear. The current focus on the physical aspects of COVID-19 infection may distract public attention from the psychosocial consequences of this outbreak. The mental disorders related to this outbreak may develop and extend FGIDs in the long term. FGIDs have a significant impact on daily activities and quality of life and also cause high economic burdens through direct medical costs and loss of productivity. The purpose of this mini-review was to emphasize the critical state of old and new cases of FGIDs during the COVID-19 outbreak. Published English papers about mental health disorders related to the COVID19 outbreak or before the infectious outbreak, stress, and FGIDs were considered and reviewed. We selected articles which were current and had the most relevance to FGIDs, psycho-somatization, and infectious outbreak.

An Unusual Presentation of Endometriosis as an Ileocolic Intussusception with Cecal Mass: A Case Report.

BACKGROUND: Bowel endometriosis affects about 3.8-37% of women with endometriosis diagnosis. Most of the time endometriosis involves the recto-sigmoid. Right colon involvement is not common in endometriosis and also a few studies have reported obstructive endometriosis of bowel. Here, a case of endometriosis was reported with the ileocolic intussusception and cecal mass. CASE PRESENTATION: A 32y old woman was referred to Yas hospital due to severe low abdominal pain and vomiting. Ultrasonographic examination of her pelvis revealed bilateral ovarian cysts. Abdominal erect X-ray showed dilatation of small bowel segments. Diagnostic colonoscopy showed one small ulcer with the pressure effect of mass like lesion at cecum. The patient was taken to the operating room for excision of the mass; as a result the ileocolic intussusception was seen. After reduction, a firm mass was recognized at cecum so the ileocecal resection was performed. In pathologic examination of mass, endometriosis was reported. The postoperative period was uneventful. CONCLUSION: The diagnosis of bowel endometriosis is sometimes difficult. The case of bowel obstructive endometriosis is rare. Surgical excision of bowel endometriosis is necessary for symptomatic patients with bowel obstruction. Bowel endometriotic nodules are excised by nodulectomy or segmental resection.

Menstrual and Reproductive Factors and Risk of Pancreatic Cancer in Women.

BACKGROUND Pancreatic cancer (PC) is a deadly disease with a 5-year survival of less than 5%. Worldwide PC incidence rates are lower among women than men. While this suggests a protective role for steroid hormones in PC risk, results from epidemiological studies are not consistent. METHODS 153 new incident PC cases and 202 controls were recruited from a prospective case-control study, running in a referral center for endoscopic ultrasonography during 2011-2017. A structured valid and reliable questionnaire was used for data collection by a few trained interviewers. Odds ratios and 95% confidence intervals for reproductive factors and PC were estimated using logistic regression methods. RESULTS Mean age (SD) of the cases and the controls were 63.18 (11.4) and 63.37 (12.0) years, respectively. Age at menarche, age at menopause, number of parity, gravidity, and abortion were not associated with PC risk. CONCLUSION This study does not support the hypothesis that menstrual and reproductive factors are associated with PC risk.

Type II Enteropathy-Associated T-cell Lymphoma: A Rare Report from Iran.

Type II enteropathy-associated T-cell lymphoma (EATL) is a rare disease that is reported from Asia, especially from Taiwan. In this paper, we present a patient from Iran (Arab) with Type II EATL whose disease was not associated with celiac disease or Epstein-Barr virus (EBV) infection. The patient died due to intestinal perforation during the first chemotherapy. Type II EATL is a gastrointestinal lymphoma with poor prognosis and a high affinity for intestinal perforation. Early detection of EATL II is essential for chemotherapy prior to the onset of malnutrition symptoms.

Report of a Rare Case of Nasal Mucosa Pyoderma Vegetans in a Patient with Ulcerative Colitis.

Some dermatologic manifestations are common in ulcerative colitis (UC). Herein, we present a 36-year-old woman with ulcerative colitis and uncommon nasal mucosa pyoderma vegetans. The patient presented to our hospital with symptoms of active colitis and a concomitant 3×4×5 cm dermato-mucosal lesion in her left nasal lumen. After surgery of the mucosal lesion, the treatment for her active colitis was initiated with intravenous infliximab and oral asacol. After a 1-year follow-up, no sign of recurrence favoring mucosal lesion was noted and symptoms of ulcerative colitis were managed properly.

Clinical and pathological features of non-functional neuroendocrine tumors of pancreas: a report from iran.

BACKGROUND Pancreatic neuroendocrine tumors (PNETs) are rare tumors with variable malignant potential, prognosis, and survival. We aimed to assess the characteristics of patients with non- functional PNET in our hospital. METHODS From Nov 2010 to Nov 2013 , all patients who came to endosonography unit of Shariati hospital , Tehran , Iran , and had pancreatic lesions were assessed . Tumor samples were obtained through fine needle aspiration. Various characteristics of the non- functional PNET were recorded and patients were followed up to three years. RESULTS Twenty eight non func-PNET cases, aged 37-72 years were identified, 15 (53.6%) of whom were men. Fifteen (53.6%) tumors were located in the head and 5(17.8%) in the body of the pancreas. The mean tumor size was 3.9 Cm and 10.7% , 28.6%, 32.1%, and 28.6% of the patients were at stages I, II, III and IV, respectively. Of the patients, 12 (43%) underwent surgery, 3 (10.7%) received chemotherapy, and 13 (46.4%) received no treatment. During the mean follow-up of 16 months, the disease had progressed in 3 (10.7%) patients and 10 (35.7%) had died. In univariate analysis, tumor size>3Cm and Ki-67>20% were correlated with survival rate but not in multivariate analysis. CONCLUSION Iranian patients with non- functional PNET present similar characteristics to world patients. There is a need to establish efficacy of tumor samples which are obtaining through fine needle aspiration for assessing tumor grading.

Systemic lupus erythematosus presenting with a fatal intestinal vasculitis: a case report.

This case report demonstrates fatal gastrointestinal vasculitis as a rare presentation of systemic lupus erythematosus. A 34-year-old woman presented with abdominal pain and diarrhea. Anti nuclear antibody was positive and high titre of anti-ds DNA antibody was also reported. Treatment with corticosteroid and supportive cares were started; however, her condition worsened. Eventually, she was considered as a candidate for diagnostic laparoscopy. Immediately after laparoscopy, she developed respiratory distress along with upper gastrointestinal bleeding. Soon after, the patient died because of disseminated intravascular coagulation .

Long-term Outcome of Budd-Chiari Syndrome: A Single Center Experience.

BACKGROUND: Budd-Chiari syndrome (BCS) is defined as hepatic venous outflow obstruction(HVOO). BCS is an uncommon, life-threatening liver disorder. This studydescribes the clinical and etiological characteristics in addition to the longtermoutcome of BCS in a single referral center in Tehran, Iran. METHODS: We reviewed long-term outcome of patients who were diagnosed with BCSbetween 1989 and 2012 at Shariati Hospital, a tertiary hospital affiliated withTehran University of Medical Sciences, Tehran, Iran. The diagnosis was confirmedby at least two imaging techniques. A comprehensive analysis of theclinical and paraclinical manifestations, etiology and long-term outcome of thedisease was conducted. RESULTS: Seventy one patients (43 female) with a diagnosis of Budd-Chiari syndromewere identified during the 22 year period of study. The age were ranged from17 to 64 years (median: 29 years). We excluded 16 patients because of incompleteinformation or follow up. The remaining 55 cases were the subjects ofthis study. Underlying etiologies consisted of congenital thrombophilia factorsin 50% (28 cases) which was defined as protein C deficiency (12 cases),protein S deficiency (3 cases), antithrombin deficiency (3 cases) and factor VLeiden mutation (10 cases). Etiology was unknown in 18% (10 cases). Acquiredcauses of thrombophilia were observed in 25% (14 cases) that consistedof 9 cases of myeloproliferative disease and 5 cases of autoimmune diseases.In 3 cases pregnancy was the only etiology. The main clinical presentationswere abdominal pain in 33 (60%), abdominal distention in 21 (38.2%), andjaundice in 10 (18%) cases. The main clinical signs were ascites (76.4%), splenomegaly(34%), hepatomegaly (25.5%) and deep vein thrombosis (1.8%). All55 patients were treated with anticoagulants (heparin followed by warfarin)and supportive care. Two cases underwent mesocaval shunt surgery, 2 patientsrequired transjugular portosystemic shunt (TIPS) and 5 were referred for livertransplantation. A total of 17 (30%) patients died during 22 years of follow up. CONCLUSION: BCS, although uncommon in Iran, is a challenging liver disease with an importantburden. Medical therapy that includes anticoagulation seems to be effectivein most cases although the prognosis is guarded. In long-term followup, 40% of cases will need liver transplant or die from end stage liver disease.
