RESUMO

BACKGROUND: The neutrophil percentage-to-albumin ratio (NPAR) is a novel measure of systemic inflammation and infection. Low albumin levels increase the risk of infection, while high neutrophil counts indicate the presence of infection. Spontaneous bacterial peritonitis (SBP) is a serious infection in cirrhotic ascites, and the potential of NPAR in diagnosing SBP is not yet established. OBJECTIVE: The objective of this study is to determine the diagnostic value of NPAR in identifying SBP. PATIENTS: This prospective multicenter study included 465 patients diagnosed with cirrhotic ascites and SBP according to international guidelines. Demographic, clinical, and laboratory data were collected. The sensitivity and specificity of NPAR values for diagnosing SBP were assessed using the receiver operating characteristic curve. RESULTS: For SBP diagnosis in the total cohort, NPAR of > 17 had a sensitivity of 85.71%, specificity of 66.67%, and 95% CI (42.1-99.6). In culture-positive SBP, the NPAR at a cut-off > 5.2 had a sensitivity of 85.71%, specificity of 83.33%, and 95% CI (0.709 to 0.979), while in culture-negative SBP, the NPAR at a cut-off > 2.1 had a sensitivity of 92.86%, specificity of 33.33% and CI (0.367 to 0.764). The multivariate analysis revealed that albumin (OR = 2.78, [1.11;3.98], INR (OR = 0.198, [0.066;0.596], creatinine (OR = 0.292, [0.1; 0.81], CRP (OR = 3.18, [1.239;4.52] total leukocytic count (TLC) (OR = 1.97, [1.878; 2.07], platelets (OR = 2.09, [0.99; 2.31] and neutrophil (OR = 3.43, [1.04;3.89] were significantly associated with higher prediction rates for culture positive SBP. CONCLUSIONS: NPAR could be a new, affordable, noninvasive test for diagnosing SBP.

RESUMO

The burden of chronic kidney disease and associated risk of kidney failure are increasing in Africa. The management of people with chronic kidney disease is fraught with numerous challenges because of limitations in health systems and infrastructures for care delivery. From the third iteration of the International Society of Nephrology Global Kidney Health Atlas, we describe the status of kidney care in the ISN Africa region using the World Health Organization building blocks for health systems. We identified limited government health spending, which in turn led to increased out-of-pocket costs for people with kidney disease at the point of service delivery. The health care workforce across Africa was suboptimal and further challenged by the exodus of trained health care workers out of the continent. Medical products, technologies, and services for the management of people with nondialysis chronic kidney disease and for kidney replacement therapy were scarce due to limitations in health infrastructure, which was inequitably distributed. There were few kidney registries and advocacy groups championing kidney disease management in Africa compared with the rest of the world. Strategies for ensuring improved kidney care in Africa include focusing on chronic kidney disease prevention and early detection, improving the effectiveness of the available health care workforce (e.g., multidisciplinary teams, task substitution, and telemedicine), augmenting kidney care financing, providing quality, up-to-date health information data, and improving the accessibility, affordability, and delivery of quality treatment (kidney replacement therapy or conservative kidney management) for all people living with kidney failure.

RESUMO

BACKGROUND: The prevalence of obesity has increased globally and is associated with many comorbidities such as type 2 diabetes and fatty liver and cardiovascular diseases. Bariatric surgery is considered an effective intervention for achieving weight loss and controlling lipidemia and glycemia. OBJECTIVES: This Saudi retrospective observational study evaluates the clinical and biochemical benefits following bariatric surgery to obese diabetic patients.  Methodology: After gaining ethical committee approval, data was collected from the patients' medical records at a tertiary medical center (King Fahad General Hospital, Al-Madinah Al-Munawwarah, Saudi Arabia). The total sample size was 61 patients, of whom 78.33% (n=48) had a body mass index (BMI) of 40 or greater (obese class III). RESULTS: Following bariatric surgery, there were statistically significant reductions (p<0.001) in BMI and HbA1C (decreased from 45.53±7.791 kg/m2 and 7.9±1.82% to 33.42±6.18 kg/m2 and 6.06±1.35%, respectively, after surgery). Likewise, significant reductions (p<0.001) occurred to serum total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides that decreased from 234.4±26.7 mg/dl, 152.2±19.4 mg/dl, and 187.3±24.6 mg/dl to 158.4±17.3 mg/dl, 95.6±15.7 mg/dl, and 132.5±19.5 mg/dl, respectively. Interestingly, serum high-density lipoprotein (HDL) significantly increased (p<0.001) from 43.8±6.2 mg/dl to 52.3±4.6 mg/dl. Using the novel clinical therapeutic index, bariatric surgery decreased BMI by about 26.6%. Using the novel biochemical therapeutic index, bariatric surgery decreased HbA1C, serum total cholesterol, serum LDL cholesterol, and serum triglycerides by about 22.99%, 32.42%, 37.18%, and 29.26%, respectively, while serum HDL increased by about 19.4%. CONCLUSION: Bariatric surgery is an effective intervention for obese diabetic patients resulting in weight loss, better control of diabetes and hyperlipidemia, and the metabolic profile. It is also recommended in Saudi Arabia for the high prevalence of obesity and diabetes mellitus.

RESUMO

Tumor diseases remain among the world's primary causes of death despite substantial advances in cancer diagnosis and treatment. The adverse chemotherapy problems and sensitivity towards drugs for some cancer types are among the most promising challenges in modern treatment. Finding new anti-cancer agents and drugs is, therefore, essential. A significant class of biologically active substances and prospective medications against cancer is comprised of bacterial proteins and peptides. Among these bacterial peptides, some of them, such as anti-cancer antibiotics and many toxins like diphtheria are widely being used in the treatment of cancer. In contrast, the remaining bacterial peptides are either in clinical trials or under research in vitro studies. This study includes the most recent information on the characteristics and mechanism of action of the bacterial peptides that have anti-cancer activities, some of which are now being employed in cancer therapy while some are still undergoing research.

RESUMO

BACKGROUND: Cytokines play a crucial role in regulating the function of the immune system by controlling the production, differentiation, and activity of immune cells. Occult hepatitis C virus (OHCV) infection can lead to liver damage, including cirrhosis and hepatocellular carcinoma. This study investigates the immunopathogenic impact of the cytokines IL-17 and IL-22 in OHCV infection compared to chronic hepatitis C (CHC) infection. METHODS: We studied three groups of patients: 35 with OHCV, 100 untreated patients with CHC, and 30 healthy control subjects. All subjects underwent physical examination and biochemical testing. We used the sandwich enzyme-linked immunosorbent assay method to measure serum IL-17 and IL-22 levels in all groups. RESULTS: Compared to the occult and control groups, the CHC group had significantly higher serum IL-17 levels (p < 0.001). The occult group also had higher serum IL-17 levels compared to the control group (p < 0.0001). There were no significant differences in IL-22 levels across the research groups. In the OHCV group, individuals with moderate inflammation (A2-A3) had significantly higher serum IL-17 levels than those with minimal inflammation (A0-A1), while in the CHC group, this difference was not statistically significant (p = 0.601). Neither the occult nor the CHC groups showed a correlation between serum IL-22 and inflammatory activity. There was no significant correlation between the levels of IL-17 or IL-22 and the stage of fibrosis/cirrhosis in either group. ROC curves were calculated for serum IL-17 and IL-22 levels and occult HCV infection, with cut-off values set at ≤ 32.1 pg/ml and < 14.3 pg/ml for IL-17 and IL-22, respectively. The AUROC (95%CI) was significantly higher for IL-17 than IL-22 (0.829 (0.732-0.902) vs. 0.504 (0.393-0.614), p < 0.001), suggesting that IL-17 has a stronger correlation with infection risk than IL-22. CONCLUSION: This study suggests that IL-17 may be involved in the immunopathogenesis of OHCV infection, especially in patients with moderate inflammation.

RESUMO

Objective: Malaria during pregnancy is a priority area for malaria research and control as pregnant women represent a high risk group for severe malaria, and the presentation of malaria during pregnancy varies according to the level of transmission in the area; so the aim of this study is to determine the prevalence rates of malaria parasite among pregnant women attending to Saudi Kassala Teaching hospital in Kassala state, 2022. Methods: A cross-sectional study was carried out in Saudi Kassala Teaching hospital in Kassala State. This study involved one hundred and eighty-five blood samples collected from pregnant women who was then examined by using blood films and ICT for malaria, and the data were collected by a structured questionnaire and analyzed using SPSS version 21. Results: The prevalence of malaria among pregnant women was 2.2% (95% CI: 0.006-0.054). There was no significant difference among the different age groups with respect to the prevalence of malaria (P value = 0.483). The prevalence of malaria in rural residency was 2.2%, and this was significantly more common than the urban residency (P value = 0.021). When compared across the gestational trimesters, there was no significant difference between them (P value = 0.518). The number of gravidity is not related to malaria infection (P value = 0.737). The presence of symptom compliant of malaria during pregnancy does not suggest the presence of malaria (P value = 0.152). No difference was found between the different educational levels with respect to the prevalence of malaria (P value = 0.362). The result showed that there was 1 (0.5%) negative result in ICT which was positive in blood film for malaria (BFFM) and there were 3 (1.6%) positive malaria parasites by both methods in all 185 samples with statistically insignificant differences (P = 0.703). Conclusion: Plasmodium falciparum was only species detected in this study. Malaria among pregnant women was more prevalent in rural areas. However, other factors such as age, gestational age, gravidity, and educational level do not affect the prevalence of malaria in pregnant women. The presence of symptomatic compliant of malaria during pregnancy does not suggest the presence of malaria. The use of ICT or BFFM has similar diagnostic outcome for malaria in pregnancy.

RESUMO

It has been demonstrated that cold atmospheric plasma (CAP) accelerates the wound healing process, however the underlying molecular pathways behind this effect remain unclear. Thus, the goal of the proposed investigation is to elucidate the therapeutic advantages of CAP on angiogenesis, pyroptotic, oxidative stress, and inflammatory mediators during the wound-healing mechanisms associated with diabetes. Intraperitoneal administration of streptozotocin (STZ, 60 mg/Kg) of body weight was used to induce type-1 diabetes. Seventy-five male mice were randomized into 3 groups: the control non-diabetic group, the diabetic group that was not treated, and the diabetic group that was treated with CAP. The key mediators of pyroptosis and its impact on the slow healing process of diabetic wounds were examined using histological investigations employing H&E staining, immunohistochemistry, ELISA, and Western blotting analysis. Angiogenesis proteins (VEGF, Ang-1, and HO-1) showed a significant decline in expression concentrations in the diabetic wounds, indicating that diabetic animals' wounds were less likely to heal. Furthermore, compared to the controls, the major mediators of pyroptosis (NLRP-3, IL-1ß, and caspase-1), oxidative stress (iNOS and NO), and inflammation (TNF-α and IL-6) have higher expression levels in the diabetic wounds. These factors substantially impede the healing mechanism of diabetic wounds. Interestingly, our results disclosed the therapeutic impacts of CAP treatment in the healing process of diabetic wounds via significantly regulating the expression levels of angiogenesis, pyroptosis, oxidative stress and pro-inflammatory mediators. Our findings demonstrated the curative likelihood of CAP and the underlying mechanisms for enhancing the healing process of diabetic wounds.

RESUMO

Hematological disorders are common medical ailments constituting an important cause of morbidity and mortality worldwide, which may be managed efficiently using different prophetic medicine remedies as adjuvants to current therapeutics. Prophetic medicine includes the body of knowledge about medicine that has been derived from the deeds, customs (sunnah), ahadith (sayings), actions, and agreements of Prophet Muhammad, peace be upon him. This review article aims at exploring the magnitude of therapeutic benefits of prophetic medicine remedies as adjuvant treatments to many different types of hematological disorders. Herein, we reviewed many published research studies throughout the literature to delineate the potential therapeutic benefits of prophetic remedies on hematological disorders. Several types of hematological disorders may benefit from prophetic medicine remedies that are rich in natural antioxidants that combat oxidative stress-induced harm e.g. nigella sativa, oral honey, camel milk and urine, Ajwa date fruits, olive oil, Zamzam water and figs. Many prophetic medicine remedies were reported to decrease the hematological cytotoxicity effects induced by different chemicals and are beneficial in treating anemias e.g. iron deficiency anemia, sickle cell anemia, thalassemia, coagulopathies and hematological malignancies as leukemia and myeloma. These remedies treat or alleviate the different hematological disorders using different mechanisms e.g. modulating the immune function, treating deficiencies of different substances, protecting against toxins-induced cytotoxicity, decreasing platelets aggregation, suppressing clotting factors activation, exerting antineoplastic effects (enhancing cancer cells cytotoxicity) and inhibiting angiogenesis. Prophetic medicine remedies exert clinically significant therapeutic benefits for treating COVID-19 pandemic, anemia, thrombosis, thalassemia and blood cancers without inducing toxicity or side effects.

RESUMO

Viral hepatitis progresses to liver cirrhosis and HCC. Several challenges are facing Sovaldi treatment to viral C hepatitis, eg, viral resistance, difficulty to treat all genotypes, and inability to access treatments in low-income countries. Also, current treatments to Hepatitis B are still challenging. Ideal treatments to viral hepatitis should decrease the viral load, enhance antiviral immunity and repair the viruses-induced tissue damage. That is still beyond reach. High serum ferritin in viral hepatitis correlates with chronicity, increased necro-inflammation, hepatotoxicity, progression to cirrhosis, progression to HCC, unresponsiveness to treatments and viremia. Previously, Al-hijamah (wet cupping therapy of prophetic medicine) significantly cleared thalassemic children of causative pathological substances (CPS), eg, excess ferritin, free radicals and serum lipids. Moreover, Al-hijamah significantly increased the antioxidant power and potentiated the natural antiviral immunity, eg, increasing CD4 count, CD8 count and CD4/CD8 ratio. Prophet Muhammad peace be upon him said: "If there is a benenvolence (benefit) in any of your medicines, benefit will be in shrtat mihjam (Al-hijamah), honey drink, and a stinge of fire compatible with disease and I do not like to cauterize". Likewise, the author suggests Al-hijamah as a novel promising adjuvant treatment for viral hepatitis (B and C) for percutaneous excretion of CPS as hepatitis viral particles, excess ferritin, inflammatory mediators, free radicals, and antigen-antibody complexes. Published reports proved that Al-hijamah exerted tissue-protective effects, and cleared blood through the fenestrated skin capillaries in a pressure-dependent and size-dependent manner (a kidney-like manner). That collectively may decrease the viral load for better HCC prevention and supports the evidence-based Taibah theory (Taibah mechanism). Same therapeutic benefits apply to other viral illnesses as AIDS. Even after HCC development, Al-hijamah is quite mandatory for excretion and clearance of CPS that favor malignancy, eg, lactate (Warburg effect), growth factors, metalloproteinases, and others. Al-hijamah-induced immune potentiation benefits HCC patients. Combining Al-hijamah with other natural antioxidant remedies of prophetic medicine, eg, nigella sativa, costus, natural honey, Zamzam water and others will maximize the therapeutic benefits. In conclusion, Al-hijamah and other prophetic medicine remedies are recommended adjuvants to current pharmacological treatments to viral hepatitis and HCC.

RESUMO

Background: The present study presents our experience with computed tomography (CT)-guided stereotactic surgery in managing deep-seated brain lesions and provides a background in the expanding fields of morphological stereotactic neurosurgery. Methods: We conducted this retrospective cohort study on 80 patients managed at the Department of Neurosurgery, Zagazig University Hospitals, Zagazig, Egypt, between January 2019 to January 2021. We targeted patients with morphological stereotactic surgeries performed as the primary management modality of their treatment. Results: A total of 80 patients, with a mean age of 44.3 years, were included in the study. The stereotactic targets were supratentorial in 71 patients (88.75%), infratentorial in seven patients (8.75%), and both supraand infratentorial in two patients (2.5%). The lesions showed enhancements with IV contrast in 55 patients (68.75%). Stereotactic procedures were performed under local anesthesia in 64 patients and general anesthesia in 16 patients. Of the 80 stereotactic procedures, 52 were biopsies (65%). We observed a significant improvement in the postoperative Karnofsky performance score compared to the postoperative score (63.4 ± 19.8 vs. 56.7 ± 15.4, P = 0.001). The level of agreement between clinical, radiological, and final pathological diagnosis was assessed; it was complete in 47.5% of the patients. The postprocedural CT scan demonstrated intracranial hemorrhage in five patients (6.25%); four (5%) were silent with no neurological complications. Conclusion: This study provided evidence that the stereotactic procedure is easy to perform, accurate in targeting the lesion, and spares patients from undergoing major surgical procedures. Stereotactic applications of spontaneous intracerebral hemorrhage, deep-seated abscesses, encysted tumors, or medically refractory benign intracranial hypertension can improve the outcome even in medically high-risk patients.

RESUMO

Treating estrogen-dependent diseases like endometriosis with drugs suppressing local estrogen activation may be superior to existing endocrine therapies. Steroid sulfatase (STS) and 17ß-hydroxysteroid dehydrogenase type 1 (17ß-HSD1) are key enzymes of local estrogen activation. We describe the rational design, synthesis, and biological profilation of furan-based compounds as a novel class of dual STS/17ß-HSD1 inhibitors (DSHIs). In T47D cells, compound 5 showed irreversible inhibition of STS and potent, reversible inhibition of 17ß-HSD1. It was selective over 17ß-HSD2 and displayed high metabolic stabilities in human and mouse liver S9 fractions. No effect on cell viability was detected up to 31 µM (HEK293) and 23 µM (HepG2), respectively, and there was no activation of the aryl hydrocarbon receptor (AhR) up to 3.16 µM. Single daily application to mice revealed steady-state plasma levels high enough to make this compound eligible for an in vivo proof-of-principle study in a mouse endometriosis model.

RESUMO

BACKGROUND AND AIM: There is lack of 30-day hospital readmission prediction score in patients with liver cirrhosis and SBP. The aim of this study is to recognize factors capable of predicting 30-day readmission and to develop a readmission risk score in patients with SBP. METHODS: This study prospectively examined the 30-day hospital readmission for patients previously discharged with a diagnosis of SBP. Based on index hospitalization variables, a multivariable logistic regression model was implemented to recognize predictors of patient hospital readmission within 30 days. Consequently, Mousa readmission risk score was established to predict 30-day hospital readmission. RESULTS: Of 475 patients hospitalized with SBP, 400 patients were included in this study. The 30-day readmission rate was 26.5%, with 16.03% of patients readmitted with SBP. Age ≥ 60, MELD > 15, serum bilirubin > 1.5 mg/dL, creatinine > 1.2 mg/dL, INR > 1.4, albumin < 2.5 g/dL, platelets count ≤ 74 (103/dL) were found to be independent predictors of 30-day readmission. Incorporating these predictors, Mousa readmission score was established to predict 30-day patient readmissions. ROC curve analysis demonstrated that at a cutoff value ≥ 4, Mousa score had optimum discriminative power for predicting the readmission in SBP with sensitivity 90.6% and specificity 92.9%. However, at cutoff value ≥ 6 the sensitivity and specificity were 77.4% and 99.7%, respectively, while a cutoff value ≥ 2 had sensitivity of 99.1% and specificity of 31.6%. CONCLUSIONS: The 30-day readmission rate of SBP was 25.6%. With the suggested simple risk assessment Mousa score, patients at high risk for early readmission can be easily identified so as to possibly prevent poorer outcomes.

RESUMO

Traumatic dislocation of the lumbosacral joint is a rare and severe lesion usually caused by high-energy trauma. The literature on traumatic spondylolisthesis is limited, and most published papers are sporadic case reports. By presenting the case of an anterior traumatic L5-S1 spondylolisthesis without neurological deficits caused by a 6-meter fall, we discuss the anatomopathological mechanism of this injury, clinical and radiological evaluation, and current management options. The patient was treated surgically with a combined posterior instrumented reduction and transforaminal interbody fusion. At the final follow-up after seven years, the radiological evaluation showed an unchanged spondylolisthesis reduction with reliable fusion healing. In addition, the patient had good functional results and resumed recreational activities and work. Traumatic lumbosacral spondylolisthesis requires a careful and well-documented initial clinical and radiological assessment. Most authors advocate surgical treatment as the mainstay of management. However, the long-term prognosis remains unclear and unpredictable.

RESUMO

Cancer cells strongly upregulate glucose uptake and glycolysis to produce vital biomolecules for cancer cell survival, proliferation, and metastasis as ATP, lipids, proteins, nucleotides, and lactate. The Warburg effect is tumours' unique glucose oxidation to give lactate (not pyruvate) even in the presence of oxygen. Nicotinamide adenine dinucleotide (NAD/NADH.H) is used in glycolysis via glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and lactate dehydrogenase (LDH). Both catalyse reversible biochemical reactions to produce 1,3-diphosphoglycerate and lactate, respectively. In this expert opinion and based on published evidence, the author suggests that: "In transformed cells and hyperglycolytic cancer cells, the Warburg effect (permanent conversion of pyruvate to lactate) occurs secondary to a vicious cycle and a closed circuit between GAPDH and LDH (reaction of carcinogenesis) causing increased endogenous oxidative stress and subsequent carcinogenesis. Mitochondrial defects in cancer cells cause hyperglycolysis resulting in NADH.H accumulation (produced during GAPDH step) that obligatorily drives LDH to become an irreversible reaction in the direction of lactate formation (Warburg effect) but not pyruvate formation. Likewise, LDH oxidizes NADH.H producing excessive NAD+ that secondarily drives GAPDH reaction to be irreversible to produce NADH.H and so on. Pyruvate is an antioxidant while lactate is pro-oxidant, causing increased endogenous oxidative stress in cancer cells, tumour's hypoxia and obligatory hyperglycolysis with NADH.H overproduction (GAPDH step) to be consumed in the LDH step for lactate production and NAD+ generation (utilized by GAPDH) and so on". This confirms Warburg's origin of cancer cells. Best anticancer applications based on this hypothesis are: breaking this closed vicious circle using siRNA to target GAPDH and LDH, avoiding strong oxidants (as many cancer chemotherapeutics), and using strong antioxidants for causing antioxidant-oxidant antagonism or antioxidant-lactate antagonism to inhibit the Warburg effect. Strong natural antioxidants of prophetic medicine (related to Prophet Muhammad peace be upon him) such as Zamzam water, Nigella sativa, costus, Ajwa date fruit, olive oil, Al-hijamah and natural honey are strongly recommended to prevent and antagonize the Warburg effect.

RESUMO

BACKGROUND: Paracetamol (acetaminophen) is an over-the-counter non-steroidal anti-inflammatory drug that may cause acute toxic overdosage particularly in neuropsychiatric patients. Paracetamol is also very commonly prescribed as an analgesic and antipyretic agent. Paracetamol toxicity causes decreased reduced glutathione and oxidative tissue damage. Aleppo galls is a promising natural remedy exerting antioxidant and tissue-protective effects that may combat acetaminophen-induced oxidative tissue damage. METHODOLOGY: Biochemical and toxicological effects of a toxic dose of paracetamol (250 mg/kg) were investigated for three consecutive days versus the tissue-protective effects of Aleppo galls. Eighteen white albino mice were randomly allocated in this study and divided into three experimental groups (six mice per group): negative control (received intraperitoneal sterile water injection), paracetamol toxicity group (received intraperitoneal paracetamol injection) and the third group (received paracetamol injection at 250 mg/kg/day together with oral Aleppo galls treatment at 250 mg/kg/day for 3 consecutive days). All mice were sacrificed by the end of the study. RESULTS: Our data revealed that paracetamol toxicity exerted significant oxidative stress damaging effects (high serum malondialdehyde, decreased serum catalase and decreased total antioxidant capacity), and significant inflammatory effects (high serum IL-6) and significant tissue-damaging effects (high serum LDH). Aleppo galls treatment significantly protected against acetaminophen toxicity-induced oxidative stress effects (P<0.001), inflammatory effects (P<0.001) and tissue-damaging effects (P<0.001). CONCLUSION: Aleppo galls are promising for future drug therapeutics and for the synthesis of natural remedies for treating paracetamol toxicity. We recommend formulating Aleppo galls extract as a pharmaceutical nutrition and to be given to those who need to take large doses of paracetamol.

RESUMO

BACKGROUND: Acute paracetamol toxicity is a common and potentially life-threatening emergency causing liver failure that may necessitate liver transplantation. Unfortunately, current therapies are still defective. OBJECTIVES: To investigate the protective effects exerted by Aleppo galls (Quercus infectoria Olivier) extract against acute paracetamol toxicity in mice. METHODOLOGY: Eighteen mice were divided into three experimental groups, each included six mice in each group. The groups included: negative control group, paracetamol toxicity group that received an acute toxic intraperitoneal dose of paracetamol (250 mg/kg) for four consecutive days, and treatment group (received 250 mg/kg paracetamol followed few hours later by Aleppo galls extract for the same duration). Animals were anaesthetized using ether anaesthesia. Animals were sacrificed by decapitation and blood samples were drawn. Paracetamol toxicity effects versus Aleppo galls protection were evaluated on liver function tests, liver histology, serum cholesterol and serum triglycerides. RESULTS: Acute paracetamol toxicity caused significantly elevated serum transaminases (ALT and AST), decreased serum albumin, and increased serum cholesterol and triglycerides. Aleppo galls extract exerted significant protective effects and restored near normal serum levels of the previously-mentioned parameters. Upon histopathological evaluation, mice in the control group showed normal hepatic architecture with preserved hepatic cords and sinuses. Acute paracetamol toxicity induced peripheral zonal degeneration with focal necrosis of the hepatic tissue. The hepatocytes showed cytoplasmic vacuolation with indistinct cell borders. Central hepatic venules were congested. Administration of Aleppo galls extract reduced the tissue damaging effects induced by paracetamol toxicity with only minimal residual degenerative changes that were observed with absent necrosis. CONCLUSION: Quercus infectoria Olivier (Aleppo galls) is a promising source of phytochemicals and future therapeutics.

RESUMO

BACKGROUND: Synovial chondromatosis is an uncommon benign condition characterized by synovial membrane proliferation and metaplasia. Synovial chondromatosis cases in patients with rheumatoid arthritis have been reported. However, involvement of the glenohumeral joint is rare. CASE PRESENTATION: We herein report a case of a rare association of synovial chondromatosis involving the shoulder in a rheumatoid arthritis patient. The symptoms have improved with anti-tumor necrosis factor drugs. Consequently, there was no need for invasive therapy to treat synovial chondromatosis. CONCLUSION: Synovial chondromatosis can be aggressive and destructive. More trials are needed to establish a better clinical diagnostic strategy and pharmacological management.

RESUMO

In the present work, polynomial, discrete singular convolution and sinc quadrature techniques are employed as the new techniques to derive accurate and efficient numerical solutions for the reaction-diffusion equations. Three models, Fitzhugh-Nagumo, Newell-Whitehead-Segel, and tumor growth models, were presented. The equations of three models are reduced to nonlinear ordinary differential equations by using different quadrature schemes. Then, Runge-Kutta fourth-order method is employed to solve nonlinear ordinary differential equations. In addition, the MATLAB program is used to solve these problems. Comparisons between the new methods and the existing ones are included, demonstrating the ease of implementation and efficiency. Also, the calculated results are supported by four various statistical errors. It is found that the rate of error reaches ≤ 10-6 in discrete singular convolution depending on regularized Shannon kernel which is better than others. Further, a parametric analysis is presented to discuss the influence of diffusion and reaction parameters on the solution.

RESUMO

INTRODUCTION: Medical education has progressed considerably. Information and communication technologies have been adopted as a learning tool. AIM: We aimed to evaluate the contribution of an educational video in the acquisition of knowledge on the measurement of the Schöber index in young medical students. METHODS: This is a prospective study, spread over 4 months (February 2022-May 2022) and conducted in the rheumatology and orthopedics departments of the Charles Nicolle Hospital in Tunis. We included medical students during their externship at the mentioned services. We compared the realization of the steps of the Schöber test (testing the flexibility of the lumbar spine) before and after the visualization of an educational video. RESULTS: A total of 32 students (6 men and 26 women) were enrolled. There were 18 students (56%) in DCEM1 and 14 students (44%) in PCEM2. Our study showed that the number of students who correctly performed the different steps of the Schöber test increased after viewing the instructional video compared to the beginning, but this increase was not significant. There were some differences between the PCEM2 and DCEM1 groups before viewing the video, but this difference decreased after viewing the video. CONCLUSION: Our study has demonstrated the value of an educational video in improving the knowledge of medical students. This work needs to be applied on a larger scale in different medical specialties.

RESUMO

Impaired wound healing is one of the most critical complications associated with diabetes mellitus. Infections and foot ulcers are major causes of morbidity for diabetic patients. The current treatment of diabetic foot ulcers, commonly used antibiotics, is associated with the development of bacterial resistance. Hence, novel and more effective natural therapeutic antibacterial agents are urgently needed and should be developed against the pathogenic bacteria inhabiting diabetic wounds. Therefore, the current study aimed to investigate the impact of fig latex on pathogenic bacteria and its ability to promote the healing process of diabetic wounds. The pathogenic bacteria were isolated from patients with diabetic foot ulcers admitted to Assiut University Hospital. Fig latex was collected from trees in the Assiut region, and its chemical composition was analyzed using GC‒MS. The antibacterial efficacy of fig latex was assessed on the isolated bacteria. An in vivo study to investigate the effect of fig latex on diabetic wound healing was performed using three mouse groups: nondiabetic control mice, diabetic mice and diabetic mice treated with fig latex. The influence of fig latex on the expression levels of ß-defensin-1, PECAM-1, CCL2 and ZO-1 and collagen formation was investigated. The GC‒MS analysis demonstrated the presence of triterpenoids, comprising more than 90% of the total latex content. Furthermore, using a streptozotocin-induced diabetic mouse model, topical treatment of diabetic wound tissues with fig latex was shown to accelerate and improve wound closure by increasing the expression levels of ß-defensin-1, collagen, and PECAM-1 compared to untreated diabetic wounds. Additionally, fig latex decreased the expression levels of ZO-1 and CCL2.
