Mycosis Fungoides Diagnosis Using TOX Versus Old Panel Immunohistochemical Markers
Background: For primary cutaneous lymphoma, mycosis fungoides (MF) is the most prevalent form with skin-homing T cells plus clonal proliferation of CD4. In many CTCLs, thymocyte selection associated with the HMG-box (TOX) is an uncontrolled gene, together with MF in comparison with controls. Early mycosis fungoides is difficult to diagnose, and, its distinction from inflammatory diseases is sometimes impossible.
Objective: In this study, we compared the TOX vs C7 and CD4 expression as an early mycosis fungoides diagnostic markers & to assess their ability to differentiate Mycosis fungoides from benign cutaneous inflammatory diseases (BCID).
Materials and methods: 60 patients who had been previously diagnosed as MF (30 cases) and BCID (30 cases). All were evaluated histopathologically using H & E and immunohistochemically staining for TOX, CD7 & CD 4.
Results: There was statistically significant difference between MF and BCID with increased TOX, CD7 & CD4 expression among MF than among BCID and ability of TOX to detect all true positive cases (100.0%) compared to 83.3% for CD4 and 13.3% for CD7. TOX had the highest sensitivity (100.0%) and accuracy (88.3%) followed by CD4 with sensitivity of 88.3% and accuracy of 66.7%, (P < 0.001).
Conclusion: TOX had the highest sensitivity (100.0%) & accuracy (88.3%) followed by CD4 with sensitivity of 88.3% and accuracy of 66.7%. Our results suggest that TOX is a useful marker in diagnosis of MF & differentiating it from BCID

Role of Health Education in Raising Tetanus Toxoid Vaccination Coverage among Pregnant Women and Mothers with Newborns in Khartoum North-Sudan, 2019
Tetanus is an acute disease caused by the toxin of a bacterium called Clostridium tetani which is often found in soil. It is a life-threatening bacterial disease, which causes severe mortality among maternal, neonatal, and young infant. It is so serious even it can waste pregnancy, harm her baby during pregnancy or after delivery. A quasi experimental community based study was conducted among pregnant women and mothers with newborns in Khartoum North Locality from 2015-2019 with the aim to assess the effectiveness of health education intervening in raising tetanus toxoid vaccination coverage among pregnant women and mothers with new born. 266 participants were selected by using a systematic random sampling technique. The intervention that continued for six months includes; health talks, home visits, video show, presentations with power points, focus groups discussion, exhibitions, distribution of printed materials, pamphlets, brochures and posters. The data was statistically analyzed by using the (SPSS) and significant t and c2 - tests. The result showed a significant increase in the participants’ knowledge after the intervention towards tetanus toxoid at P value 0.00, the mode of infection with tetanus at P value 0.00, vulnerable group to tetanus at p value is 0.00, the seriousness of the tetanus at P value 0.00, neonatal tetanus at P value 0.00. There was a significant positive modification of the participants’ attitudes towards the easiness to communicate with the health workers at P value 0.00. The result showed a significant change in the participants’ practices towards vaccination against tetanus toxic at P value 0.00 and significant change towards taking vaccine dose regularly at P value 0.00. The study recommended that Federal Ministry of Health has to conduct many health education interventions to raise the tetanus toxoid vaccination coverage
The effect of vitamin D deficiency on glycemic control in patients with type 2 diabetes mellitus
Multiple factors are involved in the development of type 2 diabetes mellitus (T2DM), but an imbalance between free radical formation and antioxidant removal is the main cause of diabetic complications. Micronutrients with antioxidant properties may have a role in the development of diabetes mellitus (DM) and its complications. Vitamin D has recently been found to have membrane antioxidant effect and a relationship to the development of T2DM, as it can modify its risk. Whether vitamin D deficiency has an effect on hyperglycemia in diabetic patients or not need further study. Our aim was to examine the effect of vitamin D deficiency on glycemic control in T2DM. We examined the vitamin D levels of 100 patients with T2DM and correlated them with fasting blood sugar and glycated hemoglobin A1c (HbA1c) levels. High levels of fasting blood sugar and HbA1c levels were significantly associated with vitamin D deficiency. Vitamin D deficiency negatively affects glycemic control in patients with T2DM
Value of biochemical markers in predicting outcome of COVID-19 infection in University Hospital, Alexandria, Egypt
This paper aims to examine the value of different biochemical markers in predicting the outcome of COVID-19 infection. A total of 140 patients with confirmed COVID-19 infection by polymerase chain reaction (PCR), different biochemical markers were tested, their relation to the outcome of the disease was monitored, and the most reliable tests were determined. The study found a significant correlation between all evaluated biochemical markers and severity of the disease, including C-reactive protein (CRP), D-dimer, alanine aminotransferase (ALT), Aspartate aminotransferase (AST), prothrombin time (PT), activated partial thromboplastin time (aPTT). In addition, ferritin, lactate dehydrogenase (LDH), procalcitonin (PCT) and Pro- Brain natriuretic peptide (proBNP) demonstrated highly sensitivity and specificity as well as significant prognostic performance. These markers were also independently significant in predicting mortality. Early assessment of biochemical markers in patients with COVID-19 can help clinicians in tailoring treatment and providing more intensive care to those with greater mortality risk. In particular, the assessment of ferritin, LDH, procalcitonin and proBNP can independently predict mortality
HER2/neu expression status of post BCG recurrent non-muscle-invasive bladder urothelial carcinomas in relation to their primary ones
Background: Transurethral resection (TUR) followed by adjuvant therapy is still the treatment of choice of Non-Muscle-Invasive Bladder Urothelial Carcinoma (NMIBUC). However, recurrence is one of the most troublesome features of these lesions. Early second resection and adjuvant BCG therapy has been shown to improve the outcome. Objective: To evaluate the prognostic value of C-erbB-2 (HER2/neu) expression status in Non-Muscle-Invasive Bladder Urothelial Carcinoma cases, before and after intravesical Bacillus Calmette Guerin (BCG immunotherapy). Materials and methods: HER2/neu expression was studied in 120 (Ta-T1) Non-Muscle-Invasive Urothelial Carcinoma cases. The expression was evaluated and compared to the expression after Bacillus Calmette Guerin (BCG) immunotherapy. Results: HER2/neu expression in low and high grade of the Non- Muscle-Invasive Urothelial Carcinoma was (38%) and (83%) respectively. The difference of the expression rates by tumor grade was statistically significant. In recurring lesions post BCG therapy, C-erbB-2 expression was markedly decreased (31.6%) when compared to its expression before therapy (65%). Conclusions: The HER2/neu expression increased as the tumor grade rose. The reduction in expression following BCG treatment in Non-Invasive transitional cell carcinoma cases could reflect a reduction of the potential malignancy of the tumor
The mechanism of action of Spirulina as antidiabetic: a narrative review
Spirulina happens to be a special type of blue-green algae that originally emerged 3.5 billion years ago and was used as a source of nutrition. Spirulina gets its name from the filaments’ spiral or helical structure, but its true name is taxonomically Genus Arthrospira which encompasses several species. The most common species are S. fusiformis, S. maxima, and S. platensis. It is rich in various nutrients and chemical components including protein, carbohydrates, lipids, vitamins, minerals, pigments, chlorophyll, and enzymes. Spirulina’s active molecules and rich nutrients make it have several pharmacological activities and uses including antioxidant, anti-inflammatory, immunomodulatory, immune system booster, anticancer, antiviral activity, and neuroprotective properties. It is also utilized as a nutritional supplement and for weight loss. Moreover, several studies confirm that Spirulina improves insulin sensitivity and reduces blood glucose levels in rat models as well as diabetic patients. The reason behind this unique behavior could be credited to the presence of several active components in it, but the action’s fundamental mechanism is still a matter of debate. Several studies have suggested different mechanisms including anti-inflammatory activity, increased insulin sensitivity, inhibition of gluconeogenesis, antioxidant activity, modulating gut microbiota composition, improved glucose homeostasis, and insulin receptor activation. Therefore, it became clear that Spirulina is a mine of active substances used as a nutritional supplement and reduces blood glucose levels or used in conjunction with other treatments to tackle type 2 diabetes. Further exploration is required to fully explain its effects on human physiology and determine optimal dosages for treatment
Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey
Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020
Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis
BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study
Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world.
Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231.
Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001).
Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication
