HERBAL MEDICINES QUESTIONNAIRE AND EVALUATION OF ATTITUDE, PERCEPTIONS AND SELF-USE AMONG HEALTH CARE PROFESSIONALS IN RAK, UAE: PILOT STUDY

Objective: The aim of this study was to assess the perceptions of different healthcare professionals towards HM. Methods: The 16-item questionnaire on the belief of health care professionals in herbal medicine was designed by the interdisciplinary task force. Eligible participants were health care providers who were English-and Arabic-literate. The response rate was 78% of participants (781 of 1000) were respondents. In total, 553 out of 781 (71%) participants indicated that they had previously used herbal medicines. The remaining 228 participants did not believe in herbal medicine due to lack of scientific evidence, ineffectiveness and other reasons. Results: The findings of this study indicate that health care professionals including pharmacists believe they have a responsibility to provide information on HM to their patients. However, the current consensus among the respondents is that current HM-focused knowledge is inadequate for such an application. Conclusion: Health care professionals believe in using HM for their needs and have a responsibility to provide information on HM to their patients

Deformation Characteristics of Base and Subbase Layers under Monotonic & Cyclic Loading

Base and Subbase layers are considered as the platform for distributing the different applied stresses in flexible pavements. The two layers must provide sufficient strength to resist any excessive generated deformation to achieve this goal, proper compaction machinery is essential to reach the required degree of compaction. The present paper investigates the influence of degree of compaction of the base and Subbase layers on the generated deformation under the action of both monotonic and cyclic loadings. Model tests were performed by compacting beds of base and Subbase layers to relative densities of 65%,77% and 88%, inside steel container of dimensions 1000mm*750mm*750mm. The final thicknesses of the base and Subbase layers were 150mm and 350mm respectively. A circular model footing of diameter 175mm: equivalent to 24194 mm tire contact area is placed on the base layer and subjected to a series of monotonic and cyclic loadings. The results of monotonic tests revealed an increase of 71% and 107% in the carrying capacity when the relative density increased from 65% to 77% and from 65% to 88% respectively. The cyclic tests revealed a substantial increase in the number of cycles at any stress level as the relative density increases from 65% to 77% and from 65% to 88%

Outcome of patients with visceral leishmaniasis in Diyala province

Background: Visceral leishmaniasis is the second largest parasitic killer in the world after malaria. Objective: The outcome of patient with visceral leishmaniasis in hospital samples depending on spot test for diagnosis. Patients and Methods: This study was conducted in Al-Batool Teaching Hospital in Baqubah- Diyala province, during the period from January 2015 to December 2015. Thirty five collecting cases were suspected to have visceral leishmaniasis. History was taken regarding residence, gender, age, animal contact, blood group type. Clinical examination and investigation were done using complete blood count, abdominal ultrasound and spot test. Results: In this study, thirty-five children were diagnosed as visceral leishmaniasis. It is found more among males (60%) than females (40%), more common in spring and winter, than in summer and autumn; which was (48.5%, 31%, 14% and 0.05%) respectively. High percentage recorded among patient with type (A) and (B) blood group, and less in (AB) and (O) (57%,22%,5%,14%) respectively also infection in rural area (71%) more than in urban (29%). Regarding the site of infection, organomegaly was (57%), splenomegaly (14%), hepatomegaly (17%), hepatosplenomegaly (26%) no-organomegaly(43%). All patients were anemic (43%), mild anemia (10 mg% and less) and (57%) severe anemia (7mg% and less). The percentage of duration of fever was 17%2 weeks. Conclusion: Visceral leishmaniasis is a common in patients live in rural areas that have contact with animals (Dog, fox and jackals)

MTA1 Expression Correlates Significantly with Histologic Grade in Salivary Mucoepidermoid Carcinoma

Background: Metastasis associated protein-1 (MTA1) has been a recently identified as a unique gene playing important role in tumorigenesis and progression of cancer cells. Objective:To evaluate MTA1 expression and its predictive value in determining histologic grade of salivary mucoepidermoid carcinoma (MEC).   Patients and Methods: MTA1 expression was evaluated by immunohistochemistry in paraffin-embedded tumor specimens blocks from 22 patients. Assessment of MTA1 immunostaining was achieved by counting the proportion of positively-stained tumor cells in 5 high power microscopic fields; and staining was analyzed in relation to clinicopathological variables.  Results: MTA1 show nuclear and cytoplasmic expression in varying intensity in 95% of cases. No significant correlation was found between MTA1expression and age, gender, site of the tumor (p>0.05). However, statistically significant correlation was found between MTA1expression and clinical stage, nodal involvement (p=0.009 and 0.007; respectively). Regarding histologic grade, high MTA1 level was significantly associated with grade of tumors categorized by Auclair and Brandwein systems (<0.001 and 0.009; respectively). Conclusion:MTA1 expression significantly correlates with tumor grade and progression, and has a potential role in diagnosis and prediction of behavior in salivary MEC

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

PANC Study (Pancreatitis: A National Cohort Study): national cohort study examining the first 30 days from presentation of acute pancreatitis in the UK

Abstract Background Acute pancreatitis is a common, yet complex, emergency surgical presentation. Multiple guidelines exist and management can vary significantly. The aim of this first UK, multicentre, prospective cohort study was to assess the variation in management of acute pancreatitis to guide resource planning and optimize treatment. Methods All patients aged greater than or equal to 18 years presenting with acute pancreatitis, as per the Atlanta criteria, from March to April 2021 were eligible for inclusion and followed up for 30 days. Anonymized data were uploaded to a secure electronic database in line with local governance approvals. Results A total of 113 hospitals contributed data on 2580 patients, with an equal sex distribution and a mean age of 57 years. The aetiology was gallstones in 50.6 per cent, with idiopathic the next most common (22.4 per cent). In addition to the 7.6 per cent with a diagnosis of chronic pancreatitis, 20.1 per cent of patients had a previous episode of acute pancreatitis. One in 20 patients were classed as having severe pancreatitis, as per the Atlanta criteria. The overall mortality rate was 2.3 per cent at 30 days, but rose to one in three in the severe group. Predictors of death included male sex, increased age, and frailty; previous acute pancreatitis and gallstones as aetiologies were protective. Smoking status and body mass index did not affect death. Conclusion Most patients presenting with acute pancreatitis have a mild, self-limiting disease. Rates of patients with idiopathic pancreatitis are high. Recurrent attacks of pancreatitis are common, but are likely to have reduced risk of death on subsequent admissions. </jats:sec

BakerIncludes bibliographical references.M. S. University of Missouri--Columbia 2012."December 2012"[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The primary goal of this research was to decrease the quantities of CO2 emission gases in the emission sources by absorption process using synthesized and modified solid sorbent materials that are readily available, inexpensive and chemically selective toward CO2. Calcium oxide (CaO) was one of these solid sorbents that have been investigated and synthesized for CO2 capture at high temperatures by a calcination method from calcium acetate as a precursor. Functionalized solid sorbents, with dopant (graphite nanoplates) aimed to increase surface area and pore volume, showed the highest capacity capture of (0.68 mg of CO2 / mg of sorbent) at 600[degrees]C and were fully regenerated at 850[degrees] C. Additionally, different percentages of dopants in the CaO were tested. The best distribution dopant in the calcite body was the CaO-20%nanoplates. The second solid sorbent that has been investigated for capturing CO2 at low temperatures was Jeffamine/silica solid sorbents. By incorporating different Jeffamines (polymers) into a support of different sized nanosilica, quasi-solid-state sorbents were synthesized. Different ratios of Jeffamines to nanosilica were investigated. The mass ratio 1:1 (w:w) T-403/14 nm silica had the highest CO2 uptake close to 70 mg of CO2 per gram of sorbent at 45[degrees]C and capable of fully ([about]90%) regenerated using simple vacuum swing. Kinetics study of the sorbent was also investigated, showed rapidly chemisorb CO2 in almost 2 min and can be regenerated easily in 10 min
