Evaluation of the anti-infective potential of the seed endophytic fungi of Corchorus olitorius through metabolomics and molecular docking approach.

BACKGROUND: Endophytic fungi are very rich sources of natural antibacterial and antifungal compounds. The main aim of this study is to isolate the fungal endophytes from the medicinal plant Corchorus olitorius seeds (F. Malvaceae), followed by antimicrobial screening against various bacterial and fungal strains. RESULTS: Seven endophytic fungal strains belonging to different three genera were isolated, including Penicillium, Fusarium, and Aspergillus. The seven isolated endophytic strains revealed selective noticeable activity against Escherichia coli (ATCC25922) with varied IC50s ranging from 1.19 to 10 µg /mL, in which Aspergillus sp. (Ar 6) exhibited the strongest potency against E. coli (ATCC 25,922) and candida albicans (ATCC 10,231) with IC50s 1.19 and 15 µg /mL, respectively. Therefore, the chemical profiling of Aspergillus sp. (Ar 6) crude extract was performed using LC-HR-ESI-MS and led to the dereplication of sixteen compounds of various classes (1-16). In-silico analysis of the dereplicated metabolites led to highlighting the compounds responsible for the antimicrobial activity of Aspergillus sp. extract. Moreover, molecular docking showed the potential targets of the metabolites; Astellatol (5), Aspergillipeptide A (10), and Emericellamide C (14) against E. coli and C. albicans. CONCLUSION: These results will expand the knowledge of endophytes and provide us with new approaches to face the global antibiotic resistance problem and the future production of undiscovered compounds different from the antibiotics classes.

Prevalence of Enuresis in Children, Adolescents, and Young Adults Diagnosed With Attention Deficit Hyperactivity Disorder.

Background Enuresis, or bedwetting, is a common condition affecting millions of children worldwide. This can be a source of distress for both children and their families. Children, adolescents, and young adults with attention deficit hyperactivity disorder (ADHD) are at risk of developing enuresis. They have difficulties with executive functioning, including impulse control and emotional regulation. These difficulties may contribute to the development of enuresis, as individuals may struggle to recognize the urge to use the bathroom or have difficulty controlling their bladder during sleep. Objective To assess the prevalence of enuresis in children, adolescents, and young adults with ADHD and determine whether the presence of other behavioral disorders such anxiety, depression, learning disabilities, and autism comorbid with ADHD is a risk factor for developing enuresis. Method A case-control study included 213 children, adolescents, and young adults aged seven to 23 years, with 139 males and 74 females. A total of 161 participants were diagnosed with ADHD. Data collection consisted of a semi-structured interview conducted with each participant or their parents in person during their visit to Developmental Pediatric Clinics and Psychiatry Clinics. The questions were designed to collect data on the participant's ADHD diagnosis, enuresis history, other behavioral disorders, such as anxiety, depression, and learning difficulties, and any relevant medical or developmental history. The interview lasted approximately 30 minutes. Results Children, adolescents, and young adults with ADHD had a significantly higher prevalence of enuresis than the control group (13.6% vs. 0.9%, p = 0.01). Other behavioral disorders comorbid with ADHD did not pose a statistically significant risk for the development of enuresis (p = 0.36). Conclusions This study supports that children, adolescents, and young adults diagnosed with ADHD are more likely to have enuresis than those without ADHD. This finding is consistent with previous research and emphasizes the importance of a thorough evaluation and comprehensive treatment plan for individuals with ADHD.

The nutritional status of mycetoma affected patients seen at the Mycetoma Research Center, Sudan.

Nutrition plays a critical and crucial role in addressing neglected tropical diseases (NTDs) and their complications, as they often contribute to malnutrition, which can worsen the impact of these conditions. Therefore, it is necessary to investigate the nutritional status of mycetoma patients, which has not been explored previously. This descriptive cross-sectional hospital-based study was conducted at the Mycetoma Research Center (MRC), University of Khartoum, Sudan. The study included 179 confirmed mycetoma patients and an equal number of age- and sex-matched normal controls. The nutritional status of the mycetoma patients was assessed and compared with that of the control group. The majority of the patients were young adults with varying educational levels, predominantly from Central Sudan. The foot was the most commonly affected part; most patients had lesions more than 10 cm in diameter. The Body Mass Index (BMI) was calculated for both study groups, revealing that 43.5% of the patients and 53.6% of controls had a normal BMI. Furthermore, 36% of patients were underweight, contrasting with only 11% in the control group. Correlation analyses indicated no significant associations between BMI and age groups, educational levels, daily meals, food quantity, and appetite in the study population (p > 0.05). Similarly, no significant differences were observed in BMI concerning disease duration and affected sites (p = 0.0577). The Kruskal-Wallis test did not reveal significant differences in BMI means among the groups. The study revealed that most participants consumed three meals daily, and the control group showed a more robust appetite and consumed more food than the patient group (p = 0.005). Nevertheless, there were no significant differences in the consumption of different food types between the patient and control groups and among different BMI categories (p = 0.025 and 0.040, respectively).

The endophytic Fusarium strains: a treasure trove of natural products.

The complexity and structural diversity of the secondary metabolites produced by endophytes make them an attractive source of natural products with novel structures that can help in treating life-changing diseases. The genus Fusarium is one of the most abundant endophytic fungal genera, comprising about 70 species characterized by extraordinary discrepancy in terms of genetics and ability to grow on a wide range of substrates, affecting not only their biology and interaction with their surrounding organisms, but also their secondary metabolism. Members of the genus Fusarium are a source of secondary metabolites with structural and chemical diversity and reported to exhibit diverse pharmacological activities. This comprehensive review focuses on the secondary metabolites isolated from different endophytic Fusarium species along with their various biological activities, reported in the period from April 1999 to April 2022.

Refractory Hyperammonemic encephalopathy in Fibrolamellar hepatocellular carcinoma, a case report and literature review.

Fibrolamellar hepatocellular carcinoma is a rare type of hepatocellular carcinoma with unclear etiology. Its prevalence ranges from 0.6%-5%. One of the rare manifestations of FHCC includes hyperammonemic hepatic encephalopathy (HAE). Data regarding HAE in FHCC is limited to case reports, and much is unknown, including its precipitating factors, clinical course, and management. We have reported one such case of FHCC associated HAE and presented an extensive literature review on the topic. We report the case of a 26-year-old Pakistani male who was diagnosed with fibrolamellar hepatocellular carcinoma. On day five after the first chemotherapy, he presented with nausea, vomiting, and confusion. His serum ammonia level was raised, and he was treated with lactulose and rifaximin. The patient continued chemotherapy and had recurrent admissions with HAE. A detailed workup revealed acquired ornithine transcarbamylase deficiency. Ammonia level peaked at 694 umol/L during the clinical course of his disease. He received treatment with multiple ammonia scavengers, including sodium benzoate + phenylacetate, with relief of symptoms and reduction in ammonia level. The patient was eventually lost to follow-up. HAE presents as a paraneoplastic manifestation of FHCC. Patients have laboratory features suggestive of acquired ornithine transcarbamylase deficiency. There is a variable frequency of episodes reported in the literature. Most patients respond well to ammonia scavenger therapies rather than conventional HE management with lactulose or rifaxmin.

Predictors and Outcome of Ventriculoperitoneal Shunt Infection: A Retrospective Single-Center Study.

BACKGROUND: Shunt infection critically affects approximately 8-10% of all inserted shunts, leading to significant morbidity and mortality. This study aimed to assess the clinical and laboratory factors associated with shunt infection and outcomes in patients treated for hydrocephalus. Methods: A retrospective study was performed on patients who underwent ventriculoperitoneal shunt (VPS) surgery for hydrocephalus between January 2015 and June 2018. The primary outcome was the development of shunt infection following VPS surgery. Records were reviewed, and variables were analyzed, including patients' demographics, perioperative laboratory and shunt data, and outcomes. The patients had five years of follow-up from surgery, including a minimum of two years from the onset of VPS infection. RESULTS: A total of 132 shunts were inserted in 103 patients with a mean age of 2 years (range; 2 days to 73 years), and 53.4% were males. Twenty-two patients were suspected of having VPS infection (16.7% per procedure); only six (4.5%) had positive cerebrospinal fluid (CSF) detected organisms. Patients with preoperative hemoglobin, white blood cells, and serum glucose within normal values had a lower shunt infection rate. The pediatric population had an elevated risk of VPS infection, particularly those who underwent surgery at a younger age than 7.5 months, weighed less than 10 Kg, and were associated with myelomeningocele. in addition, a shorter surgery time of less than 82 min, single surgeon, and operating room of fewer than four attendees are associated with lower risk of VPS infection. CONCLUSION: We emphasize that early identification and modifications of the risk factors can minimize the probability of developing VPS infection and improve patients outcome.

Content Analysis of Media Coverage of Childhood Obesity Topics in UAE Newspapers and Popular Social Media Platforms, 2014-2017.

The 2017 prevalence of obesity among children (age 5-17 years) in the United Arab Emirates (UAE) is 13.68%. Childhood obesity is one of the 10 top health priorities in the UAE. This study examines the quality, frequency, sources, scope and framing of childhood obesity in popular social media and three leading UAE newspapers from 2014 to 2017. During the review period, 152 newspaper articles from three leading national newspapers - Gulf News, The National and Al Ittihad - met the eligibility criteria for this study. There were 57 Facebook posts, 50 Twitter posts, 14 posted YouTube videos, and 13 Media releases on related to childhood obesity between 2014 and 2017. Childhood obesity was consistently problematized, primarily in health terms, but was not strongly linked to socio-economic and geographical factors. Childhood obesity was framed as being predominantly influenced by individual and parental behaviours more frequently (n = 76) compared with structural or environmental factors such as the roles of the food and beverage industry (n = 22). Unlike findings from studies with adult obesity, articles advocating individual behavior changes to address childhood obesity were relatively few (n = 29). Social media may be an effective way to help children overcome obesity, in part through online interaction with health care providers and health conscious obese peers. Areas for improvement in social media use to reduce childhood obesity prevalence in UAE include enhancing public engagement with social media posts on childhood obesity, as reflected in the numbers of Likes and Retweets or Shares.

Epidemiology and distribution of Plasmodium vivax malaria in Sudan.

BACKGROUND: Plasmodium vivax malaria has been recognised as an important cause of morbidity in several African countries. The prevalence was previously estimated as 2-5% in eastern Sudan. These estimates are observed to be rising and spreading continuously. The present study was undertaken to investigate the situation of distribution and epidemiology of P. vivax malaria in Sudan. METHODS: Cross-sectional malaria surveys carried out in hospitals and health centres covered 21 sites in 10 states. Data and blood samples were collected from 1226 clinically investigated suspected malaria cases of both genders and all ages. Microscopically detected malaria parasites were confirmed by PCR. RESULTS: The overall prevalence of P. vivax among the malaria cases was 26.6%. The prevalence showed significant variations between the states (p<0.001), which could be explained by differences in population movement, the presence of refugees and proximity to endemic neighbouring countries. It also varied significantly with residence status (p<0.001), reflecting the stability of transmission. CONCLUSION: Although malaria in Sudan is still largely attributed to Plasmodium falciparum, P. vivax has been rising with worrying proportions and spreading to new areas. The emergence and marked increase of P. vivax poses new challenges to malaria treatment and control in Sudan.
