Background: Direct isolation of genomic DNA of mycetoma fungi from black-grains achieve rapid diagnosis and may overcome culture disadvantages. Objectives: This study aimed to isolate and assess the DNA of mycetoma fungi using black-grains and to apply amplification of ITS region and nucleotide sequences. Methods: CTAB method was followed by manual homogenization alternatively to liquid nitrogen and glass beads disruption to obtain the genomic DNA. Results: Yielded DNA concentrations vary from 1.50 to 47.97 μg/ml (mean 10.09 μg/ml) while the optimum DNA purity recorded with 75.8% of specimens (n=69/91).Successful amplification of ITS region was done using pan-fungal primers (ITS4/5) with 90.1 (n=82/91)percentage. Species nucleotide sequences were detected with 67 (94.4%) amplicons from a total of 71.Conclusion: The study recommended using of black-grain specimens for DNA extraction of mycetoma fungi parallel with culture to insure rabid diagnosis and identification

Evaluation of the Efficiency of N-terminal Pro-B-type Natriuretic Peptide for Diagnosis of Acute Myocardial Infarction

Background: Cardiac diseases are one of the major causes of death worldwide with increasing incidence rate per year, particularly in developing countries such as Sudan owing to urbanization and changing lifestyle. Myocardial infarction is a consequence of the imbalance between the heart blood supply and the required heart cell; this disorder leads to necrosis of myocardium and may cause death. It could be diagnosed by at least two of the following criteria: chest pain, electrocardiography (ECG) elevation, and levels on cardiac biomarkers. This study aimed to evaluate the efficiency of N-terminal pro-B-type natriuretic peptide (NTproBNP) for the diagnosis of acute myocardial infarction (AMI).  Methods: This analytical case–control hospital-based study was conducted on a total of 70 individuals, of which 40 participants were suspected of or diagnosed with AMI, while 30 healthy subjects  were included as a control group. Three ml of venous blood were collected in lithium heparin containers. Troponin I (TnI) as a cardiac biomarker was measured by TOSOH AIA-360, while the NTproBNP level was detected using I-Chroma II. Personal and clinical data were collected directly from each participant using a predesigned questionnaire. Results: A significant increase in the TnI level (mean: 13.13 ± 18.9 ng/ml) and NTproBNP (mean: 5756.5 ± 8378.2 pg/mL) in AMI patients were detected when compared with control mean (0.02 ± 0.00 ng/ml and 57.8 ± 42.32 pg/mL, respectively). Conclusions: NTproBNP gave a high sensitivity (87.5%), specificity (100%), positive predictive value (100%), and negative predictive value (85.7%) in the diagnosis of AMI when compared with another cardiac biomarker such as TnI.

The importance of the bioactive compounds of avocado fruit (Persea americana Mill) on human health

Mexico is the largest producer, exporter and consumer of avocados (Persea americana Mill) in the world. The demand for this fruit in some non-producing countries is currently high. The main motivation for this fruit’s consumption is its exquisite taste and pleasant texture. However, recent research has suggested that this fruit can exert protective effects on human health, as empirically determined centuries ago by the inhabitants of pre-Hispanic Mexico. These effects have been attributed to the high content of health-related compounds, including unsaturated fatty acids, acetogenins, phytosterols, tocopherols, tocotrienols, carotenoids, chlorophylls, phenols, organic acids and sugars of seven carbons. Avocado is one of the few fruits in the human diet with a high content of both water-soluble and fat-soluble health-related compounds. The main protective effects attributed to avocados include the prevention of cardiovascular diseases, diabetes and some forms of cancer, which are diseases considered in many countries as public health problems. Unfortunately, there is little research demonstrating the protective effects of avocados on human health. The aim of this work was the systematical analysis of the health-protective effects, both objectively regarded to avocado fruit, as well as those inferred from the avocado chemical composition

Mathematical evaluation of jumping distance in total hip arthroplasty: Influence of abduction angle, femoral head offset, and head diameter

Background and purpose The jumping distance (JD) is the degree of lateral translation of the femoral head center required before dislocation occurs. The smaller the distance, the higher the theoretical risk of dislocation. The aim of our study was to evaluate this jumping distance and its variation according to the characteristics of the implant, and also the theoretical gain in using large head diameters of above 38 mm

Source identification of heavy metals in Particulate Matter (PM10) in a Malaysian traffic area using multivariate techniques

This study was conducted to determine heavy metal concentrations in particulate matter (PM10) and the source identification in the areas affected by traffic during the southwest monsoon from June to July 2014. Collection of the particulate samples was done at three sampling sites that have varying traffic densities (high, medium, and low). Samples were collected using a high-volume air sampler. Heavy metals in the particulate matter (PM10) were assessed with inductively coupled plasma mass spectrometry. The results show that the mean concentrations of PM10 for high-, medium-, and low-density traffic were found to be 207.63±7.82, 164.92±10.68, and 90.09±20.70 µg m⁻³, respectively. The concentrations in high- and medium-density areas were found to be significantly higher than 150 µg m⁻³ for 24 hrs as per Recommended Malaysian Air Quality Guidelines (RMAQG). The heavy metals found were dominated by Ba and Fe, followed by Cu > V> Zn > Pb > Mn > Cr> As > Ni >Cd > Co. A comparison of the concentrations of heavy metals with the United State Environmental Protection Agency (USEPA) and World Health Organization (WHO) guidelines revealed that As was higher than the standards in high- and medium-density areas. Cluster analysis (CA) and principal component analysis (PCA) were employed in the identification of the sources of metals for high-, medium-, and low-traffic densities. The CA identified three clusters for high-, medium-, and low-traffic densities, while PCA extracted four sources for high-, medium-, and low-traffic densities and the major pollution sources identified were vehicle exhaust emission, non-exhaust emission (brake and tire wear), and re-suspension dust

Race and ethnicity in the COVID-19 Critical Care Consortium: demographics, treatments, and outcomes, an international observational registry study

Background: Improving access to healthcare for ethnic minorities is a public health priority in many countries, yet little is known about how to incorporate information on race, ethnicity, and related social determinants of health into large international studies. Most studies of differences in treatments and outcomes of COVID-19 associated with race and ethnicity are from single cities or countries. Methods: We present the breadth of race and ethnicity reported for patients in the COVID-19 Critical Care Consortium, an international observational cohort study from 380 sites across 32 countries. Patients from the United States, Australia, and South Africa were the focus of an analysis of treatments and in-hospital mortality stratified by race and ethnicity. Inclusion criteria were admission to intensive care for acute COVID-19 between January 14th, 2020, and February 15, 2022. Measurements included demographics, comorbidities, disease severity scores, treatments for organ failure, and in-hospital mortality. Results: Seven thousand three hundred ninety-four adults met the inclusion criteria. There was a wide variety of race and ethnicity designations. In the US, American Indian or Alaska Natives frequently received dialysis and mechanical ventilation and had the highest mortality. In Australia, organ failure scores were highest for Aboriginal/First Nations persons. The South Africa cohort ethnicities were predominantly Black African (50%) and Coloured* (28%). All patients in the South Africa cohort required mechanical ventilation. Mortality was highest for South Africa (68%), lowest for Australia (15%), and 30% in the US. Conclusions: Disease severity was higher for Indigenous ethnicity groups in the US and Australia than for other ethnicities. Race and ethnicity groups with longstanding healthcare disparities were found to have high acuity from COVID-19 and high mortality. Because there is no global system of race and ethnicity classification, researchers designing case report forms for international studies should consider including related information, such as socioeconomic status or migration background. *Note: “Coloured” is an official, contemporary government census category of South Africa and is a term of self-identification of race and ethnicity of many citizens of South Africa

Global access to technologies to support safe and effective inguinal hernia surgery:prospective, international cohort study

Technological advancement is important to improve healthcare quality and safety, especially in surgery1. For patients with an inguinal hernia, mesh and minimally invasive surgery are the two main technologies that have improved healthcare quality and safety2,3. The use of mesh is proven to reduce recurrence4,5. This avoids the need for further repairs, which are technically more challenging and have a higher risk for patients6. The use of minimally invasive surgery has proven advantages in bilateral hernias and in female patients2,3 and is recommended in unilateral repair where appropriate expertise is available2,3.Access to these technologies and the expertise required are not widely or equitably distributed at a global level. As it is the case for other technologies, countries in the Global South have more limited access1. At the same time, in this part of the globe, there is a higher prevalence and a higher burden of disease associated with inguinal hernias7. Several barriers to implementation in the Global South have been identified previously, including costs, distribution, and training8,9. To overcome these, studies reporting the use of mesh based on mosquito net mesh and evaluating training programmes have been conducted10,11. With these efforts and with global investment in new technologies and the expansion of existing technologies, it was expected that there would be an increase in their use in low–middle-income countries. Data assessing this variability have not been collected in a standardized way and are usually reported from single-country or single-region studies5,12. Therefore, identification of areas where improvement is most needed will be key to better inform policymakers.The overarching aim of this study was to evaluate access to technologies that are relevant to the treatment of inguinal hernia patients to identify the areas where improvement is needed. Therefore, the primary aim of this study was to evaluate the use of mesh and predictors of mesh use in elective inguinal hernia repairs and the secondary aims of this study were to evaluate the use of minimally invasive surgery and predictors of minimally invasive surgery use and to evaluate the safety associated with the use of mesh and the use of minimally invasive surgery

Outcomes of intended temporary stomas in Crohn's disease (INTESTINE study): International, multicentre, retrospective study

© The Author(s) 2025. Published by Oxford University Press on behalf of BJS Foundation Ltd.BACKGROUND: Patients with ileocolic Crohn's disease often require surgery that can result in temporary stoma formation. Stomas are associated with a morbidity and can negatively impact quality of life. This study aimed to investigate the short-term (6-month) and mid-term (18-month) outcomes of intended temporary stomas in patients with Crohn's disease. METHODS: A trainee-led, international multicentre, retrospective study was conducted on all patients who underwent surgery for Crohn's disease in collaborating centres over 4 years (2017-2020). The primary outcome was the proportion of patients with Crohn's disease who underwent stoma reversal surgery by 6- and 18-month postoperative follow-up. Secondary outcomes included: the time interval between formation and reversal of stoma and predictors for non-reversal and stoma-related morbidity (postoperative complications, related readmissions and complications due to stoma reversal surgery). RESULTS: A total of 401 patients underwent stoma formation for Crohn's disease over the 4 years across the 44 collaborating centres. The temporary stomas had been reversed in 30.2% of patients at the 6-month and 56.9% at the 18-month follow-up. Reasons for non-reversal included ongoing medical treatment for Crohn's disease (respectively 6-month and 18-month: 37.6%, 39.3%), patient unfit for surgery (respectively 6-month and 18-month: 14.5%, 16.8%), patient preference (respectively 6-month and 18-month: 12.1%, 20.2%) and due to waiting lists (respectively 6-month and 18-month: 12.1%, 8.1%). Overall, 63.3% of patients had a temporary stoma reversed with a median time interval of 6 months. The stoma-related overall morbidity rate was 29.4%. CONCLUSIONS: A large proportion of temporary stomas for Crohn's disease were not reversed at 6 and 18 months following initial surgery. Patients are exposed to the risk of non-reversal and risk of developing stoma complications for significantly longer intervals of time and, in some cases, indefinitely.Unfunde
