Knowledge, Attitude and Practice of Gynecologists at Public Teaching Hospitals in Sana'a city towards Cervical Cancer Screening, -Yemen, 2020

Background: Cervical cancer is the fourth most prevalent cancer among women causing 250, 0000 annual deaths worldwide. The available data, although limited, indicates that 8.5 million Yemeni women are at risk of developing cervical cancer and most cases are diagnosed at late stages causing deaths from this illness which could be prevented through screening. There is limited evidence about the awareness of health staff in Yemen about the importance, eligibility criteria, role and availability of cervical cancer screening as well as their attitude toward it and their utilization of this service either for themselves or their patients. The aim: to assess the knowledge, attitude, and practice (KAP) of gynecologists toward cervical cancer screening as well as barriers of implementing this screening service in Yemen. Methods: All physicians who provide gynecology and obstetrics care at the four main public teaching hospitals in Sana’a city were targeted in this cross-sectional study. The data was collected using a validated self-administered questionnaire. Findings: Gynecologists in the main public teaching hospitals in the capital of Yemen have a satisfactory knowledge of importance of screening of cervical cancer and positive attitude toward this service. However, their awareness and positive attitude are not well-reflected in the utilization of cervical cancer services, either for themselves or their patients. Barriers of using cervical cancer services include unawareness and misconceptions of gynecologists. Conclusion: The identified gap in gynecologists’ KAP and barriers should be addressed to enhance the neglected cervical cancer screening in Yemen toward better control of this serious preventable disease

Clinical Study Bedside Endoscopic Ultrasound in Critically Ill patients

Background. The aim of this study was to evaluate the role and impact of EUS in the management of critically ill patients. Methods. We retrospectively identified all patients at our institution over a 68-month period in whom bedside inpatient EUS was performed. EUS was considered to have a significant impact if a new diagnosis was established and/or the findings altered subsequent clinical management. Results. Fifteen patients (9 male; mean age 58 ± 15 years) underwent bedside EUS without complications. EUS-FNA (median 4 passes; range 2–7) performed in 12 (80%) demonstrated a malignant mediastinal mass/lymph node (5), pancreatic abscess (1), excluded a pelvic abscess (1), established enlarged gastric folds as benign (1) and excluded malignancy in enlarged mediastinal (1) and porta hepatis adenopathy (1). In two patients, EUS-FNA failed to diagnose mediastinal histoplasmosis (1) and a hemorrhagic pancreatic pseudocyst (1). In three diagnostic exams without FNA, EUS correctly excluded choledocholithaisis (n = 1) and cholangiocarcinoma (1), and found gastric varices successfully thrombosed after previous cyanoacrylate injection (1). EUS was considered to have an impact in 13/15 (87%) patients. Conclusions. In this series, bedside EUS in critically ill patients was technically feasible, safe and had a major impact on the majority of patients. 1

A preliminary study on operation management for one-way EV car sharing system in university campus

Car sharing using electric vehicles(EVs) is effective in local society and community from the viewpoint of economy and the protection of the natural environment. For instance, Univerisiti Putra Malaysia (UPM), which has two large campuses, has a plan to use a small number of small EVs as one of transportation methods. When a large number of people share a small number of vehicles in this way, the confliction of usage requests by users may cause inconvenience to users and ineffective operation of vehicles. In addition, because the degree of legal compliance with usage time and operation rules relies on social and cultural backgrounds, operation methods may be affected by them. Therefore, a framework for supporting operation management in consideration of characteristics of the local society and community is necessary in order to efficiently operate a limited number of vehicles without detracting from the convenience of users. We have been developing an operation management support system for one-way EV car sharing in the university campus to improve user convenience and vehicle operation efficiency. In this presentation, we clarify the issues of operation management for car sharing system. We also introduce an overview of the operation management support system and propose several reservation methods of vehicles

M-FISH evaluation of chromosome aberrations to examine for historical exposure to ionising radiation due to participation at British nuclear test sites

All data that support the findings of this study are included within the article (and any supplementary files).Data availability statement: All data that support the findings of this study are included within the article (and any supplementary files) available online at: https://doi.org/10.1088/1361-6498/ad1743 .Veterans of the British nuclear testing programme represent a population of ex-military personnel who had the potential to be exposed to ionising radiation through their participation at nuclear testing sites in the 1950s and 1960s. In the intervening years, members of this population have raised concerns about the status of their health and that of their descendants, as a consequence. Radiation dose estimates based on film badge measurements of external dose recorded at the time of the tests suggest any exposure to be limited for the majority of personnel, however, only ∼20% of personnel were monitored and no measurement for internalised exposure are on record. Here, to in-part address families concerns, we assay for chromosomal evidence of historical radiation exposure in a group of aged nuclear test (NT) veterans, using multiplex in situ hybridisation (M-FISH), for comparison with a matched group of veterans who were not present at NT sites. In total, we analysed 9379 and 7698 metaphase cells using M-FISH (24-colour karyotyping) from 48 NT and 38 control veteran samples, representing veteran servicemen from the army, Royal Airforce and Royal Navy. We observed stable and unstable simple- and complex-type chromosome aberrations in both NT and control veterans' samples, however find no significant difference in yield of any chromosome aberration type between the two cohorts. We do observe higher average frequencies of complex chromosome aberrations in a very small subset of veterans previously identified as having a higher potential for radiation exposure, which may be indicative of internalised contamination to long-lived radionuclides from radiation fallout. By utilising recently published whole genome sequence analysis data of a sub-set of the same family groups, we examined for but found no relationship between paternal chromosome aberration burden, germline mutation frequency and self-reported concerns of adverse health in family members, suggesting that the previously reported health issues by participants in this study are unlikely to be associated with historical radiation exposure. We did observe a small number of families, representing both control and NT cohorts, showing a relationship between paternal chromosome aberrations and germline mutation sub-types which should be explored in future studies. In conclusion, we find no cytogenetic evidence of historical radiation exposure in the cohort of nuclear veterans sampled here, offering reassurance that attendance at NTs sites by the veterans sampled here, was not associated with significant levels of exposure to radiation.Nuclear Community Charity Fund (NCCF) through funds received by The Armed Forces Covenant Fund Trust under the Aged Veterans Fund Grants AVF15A and AVF16.

Endoscopic Ultrasound-Guided Celiac Plexus Neurolysis in Pancreatic Cancer: A Prospective Pilot Study of Safety Using 10 mL versus 20 mL Alcohol

Background. The dose of alcohol used in EUS-CPN is not standardized. The objective was to compare the safety of 20 mL alcohol versus 10 mL alcohol during EUS-CPN for patients with pancreatic cancer-related pain. Methods. 20 patients were selected to receive 10 mL or 20 mL of alcohol during EUS-CPN. Followup was done at baseline, 24 hours, and weekly. Health-related quality of life (HRQoL) was assessed at baseline, week 2, week 4, and every 4 weeks thereafter until pain returned. Results. There were no major complications in both groups. Minor self-limited adverse effects were seen in 6 (30%) subjects and included lightheadedness in 1 (5%), transient diarrhea in 2 (10%), and transient nausea and vomiting in 3. Pain relief was similar in both groups: 80% in the 10 mL group and 100% in the 20 mL group (P = 0.21). The mean (± SD) duration of pain relief in the 10 mL and 20 mL groups was 7.9 ± 10.8 and 8.4 ± 9.2 weeks, respectively. 30% of patients in each group had complete pain relief. Conclusions. EUS-CPN using 20 mL of alcohol is safe. Similar clinical outcomes were seen in both groups. Further investigations to confirm these findings are warranted

Internet-based search of randomised trials relevant to mental health originating in the Arab world

BACKGROUND: The internet is becoming a widely used source of accessing medical research through various on-line databases. This instant access to information is of benefit to busy clinicians and service users around the world. The population of the Arab World is comparable to that of the United States, yet it is widely believed to have a greatly contrasting output of randomised controlled trials related to mental health. This study was designed to investigate the existence of such research in the Arab World and also to investigate the availability of this research on-line. METHODS: Survey of findings from three internet-based potential sources of randomised trials originating from the Arab world and relevant to mental health care. RESULTS: A manual search of an Arabic online current contents service identified 3 studies, MEDLINE, EMBASE, and PsycINFO searches identified only 1 study, and a manual search of a specifically indexed, study-based mental health database, PsiTri, revealed 27 trials. CONCLUSION: There genuinely seem to be few trials from the Arab world and accessing these on-line was problematic. Replication of some studies that guide psychiatric/psychological practice in the Arab world would seem prudent

Utility of EUS following endoscopic polypectomy of high-risk rectosigmoid lesions

BACKGROUND: The utility of endoscopic ultrasound (EUS) compared with standard white light endoscopy (WLE) following recent polypectomy of high-risk colorectal polyps is unknown. OBJECTIVE: To assess the incremental yield of EUS after endoscopic polypectomy of a high-risk rectal lesion. DESIGN: Retrospective cohort. SETTING: Tertiary referral center. MATERIALS AND METHODS: Patients referred for EUS following attempted endoscopic resection of a high-risk rectal neoplasm, defined as a tubulovillous adenoma, tubular adenoma with high-grade dysplasia, carcinoid, carcinoma in-situ or adenocarcinoma (CA). INTERVENTIONS: Sigmoidoscopy ± mucosal biopsy and EUS ± fine-needle aspiration (FNA) to evaluate for: (1) Residual polyp/tumor in the rectal wall or (2) peritumoral adenopathy. MAIN OUTCOME: Sensitivity and specificity for detection of residual neoplasia for WLE ± biopsy (WLE/BX) and EUS ± FNA for cancer (CA group) or benign disease (non-CA group). The incremental yield of EUS defined as: (1) Residual intramural neoplasia not present on WLE ± BX and; (2) abnormal peritumoral adenopathy. RESULTS: A total of 70 patients (mean age 64 ± 11 years, 61% male) with a final diagnosis of CA (n = 38) and non-CA (n = 32) were identified. There was no difference between the sensitivity and specificity of WLE alone (65% and 84%), WLE with biopsy (71% and 95%), and EUS (59% and 84%), for the detection of residual neoplasia (P > 0.05 for all). EUS identified 3 masses missed by WLE, all in the CA group. A malignant (n = 2) or benign (n = 3) node was identified in 5 (13%) CA patients; EUS-FNA in two showed residual malignancy in one and a reactive lymph node (LN) in one. No LNs were identified in the non-CA patients. LIMITATIONS: Retrospective design, incomplete follow-up in some patients. CONCLUSION: Following endoscopic polypectomy of high-risk rectal neoplasia, the incremental yield of EUS compared with WLE/BX for evaluation of residual disease appears limited, especially in patients with benign disease
