RESUMO

Broccoli is commonly consumed as food and as medicine. However, comprehensive metabolic profiling of two broccoli varieties, Romanesco broccoli (RB) and purple broccoli (PB), in relation to their anticholinergic activity has not been fully disclosed. A total of 110 compounds were tentatively identified using UPLC-Q-TOF-MS metabolomics. Distinctively different metabolomic profiles of the two varieties were revealed by principal component analysis (PCA). Furthermore, by volcano diagram analysis, it was found that PB had a significantly higher content of phenolic acids, flavonoids, and glucosinolates, indicating the different beneficial health potentials of PB that demonstrated higher antioxidant and anticholinergic activities. Moreover, Pearson's correlation analysis revealed 18 metabolites, mainly phenolic and sulfur compounds, as the main bioactive. The binding affinity of these biomarkers to the active sites of acetyl- and butyryl-cholinesterase enzymes was further validated using molecular docking studies. Results emphasize the broccoli significance as a functional food and nutraceutical source and highlight its beneficial effects against Alzheimer's disease.

RESUMO

This study aims to isolate the active constituents of Pyrus pyrifolia Nakai fruits using a bioassay-guided fractionation approach, test their activity in vitro against key enzymes for metabolic disorders, and support it with molecular docking simulations. The antioxidant potential of the methanolic extract (ME), its polar (PF), and non-polar fractions (NPF), along with the inhibitory activity against α-glucosidase, α-amylase, lipase, angiotensin I converting enzyme (ACE), renin, inducible nitric oxide synthase (iNOS), and xanthine oxidase (XO) were assessed. The PF exhibited the highest antioxidant and enzyme inhibitory activity. Purification of PF yielded rutin, isoquercitrin, isorhamnetin-3-O-ß-D-glucoside, chlorogenic acid, quercetin, and cinnamic acid. HPLC-UV analysis of the PF allowed for the quantification of 15 phenolic compounds, including the isolated compounds. Cinnamic acid was the most powerful antioxidant in all assays and potent enzyme inhibitor against the tested enzymes (α-glucosidase, α-amylase, lipase, ACE, renin, iNOS, and XO). Additionally, it showed high affinity to target α-glucosidase and ACE active sites with high docking scores (calculated total binding free energy (ΔGbind) -23.11 kcal/mol and - 20.03 kcal/mol, respectively]. A 20-ns molecular dynamics simulation using MM-GBSA analysis revealed a stable conformation and binding patterns in a stimulating environment of cinnamic acid. Interestingly, the isolated compounds' dynamic investigations including RMSD, RMSF, and Rg demonstrated a stable ligand - protein complex to the active site of iNOS with ΔGbind ranging from - 68.85 kcal/mol to -13.47 kcal/mol. These findings support the notion that P. pyrifolia fruit is a functional food with multifactorial therapeutic agents against metabolic syndrome-associated diseases.

RESUMO

BACKGROUND: Although community pharmacists have been actively engaged in patient care, their role in deprescribing is still restricted. OBJECTIVES: This study aimed to assess the effectiveness of a new educational approach designed to catalyze deprescribing in community pharmacies. METHODS: In this 4-month, randomized, controlled trial, 108 community pharmacies in Egypt were randomly and equally distributed to either the active or the control groups. Participants from the active group pharmacies received 31 deprescribing-related clinical case scenarios, designed according to the available deprescribing guideline and clinical experiences of an expert panel members, and delivered through WhatsApp. Then participants from both groups reported the incidence of potentially inappropriate medicines (PIMs), the frequency of deprescribing opportunities, and related pharmacist interventions. RESULTS: Pharmacists from the active group reported a considerably higher incidence of PIMs (20.87%) than that reported by pharmacists from the control group (5.03%). In addition, they made 1326 deprescribing-related interventions, of which 1022 (77.07%) were accepted and 641 (48.34%) were significant interventions. The proportions of cessation of drug therapy, reducing the dose, and persuasion of patients to accept deprescribing pharmacist interventions in the active group were 37.85%, 22.09%, and 10.63%, respectively. In contrast, 150 of 268 deprescribing-related interventions (55.97%) in the active group were accepted. The clinical value and type of deprescribing decision were statistically significant determinants for the acceptance of deprescribing decisions. The mean time needed to persuade the patient about deprescribing and the cost saved per patient across the active and the control groups were 5.09 ± 3.54 minutes versus 10.03 ± 6.19 minutes and 17.88 ± 9.60 U.S. dollars versus 4.49 ± 2.44 U.S. dollars, respectively. CONCLUSION: The intervention proposed improved the frequency and clinical value of deprescribing decisions.

RESUMO

The current study reports for the first time the nutritional, fruit volatiles, phytochemical, and biological characteristics of Ferocactus herrerae J. G. Ortega fruits. The nutritional analysis revealed that carbohydrate (20.6%) was the most abundant nutrient followed by dietary fibers (11.8%), lipids (0.9%), and proteins (0.8%). It was rich in vitamins, minerals, essential, and non-essential amino acids. Gas chromatography-mass spectrometry (GC-MS) analysis of the headspace-extracted volatiles showed that 3-methyl octadecane (35.72 ± 2.38%) was the major constituent detected. Spectrophotometric determination of total phenolic and flavonoid contents of the fruit methanolic extract (ME) showed high total phenolic [9.17 ± 0.87 mg/g gallic acid equivalent (GAE)] and flavonoid [4.99 ± 0.23 mg/g quercetin equivalent (QE)] contents. The ME was analyzed using high-performance liquid chromatography with ultraviolet (HPLC-UV), which allowed for both qualitative and quantitative estimation of 16 phenolic compounds. Caffeic acid was the major phenolic acid identified [45.03 ± 0.45 mg/100 g dried powdered fruits (DW)] while quercitrin (52.65 ± 0.31 mg/100 g DW), was the major flavonoid detected. In-vitro assessment of the antioxidant capacities of the ME revealed pronounced activity using three comparative methods; 2, 2-diphenyl-1-picrylhydrazyl (DPPH) (132.06 ± 2.1 µM Trolox equivalent (TE) /g), 2,2'-azino-di(3-ethylbenzthiazoline-6-sulfonic acid (ABTS), (241.1 ± 5.03 uM TE/g), and ferric reducing antioxidant power (FRAP) (258.9 ± 1.75 uM TE/g). Besides, remarkable anti-inflammatory [COX-1 (IC50 = 20.2 ± 1.1 µg/mL) and COX-2 (IC50 = 9.8 ± 0.64 µg/mL)] and acetylcholinesterase inhibitory (IC50 = 1.01 ± 0.39 mg/mL) activities were observed. Finally, our results revealed that these fruits could be used effectively as functional foods and nutraceuticals suggesting an increase in their propagation.

RESUMO

INTRODUCTION: (Background)The role of pharmacists revolves around providing the highest levels of care to society and ensuring the provision of medicine to all patients. However, with the spread of coronavirus disease 2019 (COVID -19), pharmacists as a very important part of healthcare professionals' team are responsible for fighting against the disease regardless of their setting of practice. The role of pharmacists will undergo a little change to extend and include other roles in order to ensure the safety of the community and limit the virus spread. Also, they will be required to obtain information from reliable sources, and to be up to date, so they can be reliable advisors to the community and raise their awareness. OBJECTIVES: The purpose of this review is to highlight community and hospital pharmacists' roles during (COVID-19) global pandemic, and to clearly illustrate how they are contributing to maintain pharmacy services continuity, supporting other healthcare professionals, and facilitating the patient's education. SUMMARY: Clinical pharmacists provide direct patient care through monitoring adverse drug reactions, ensuring individualized treatment, performing evidence-based practice, and evaluating drugs in clinical trials. On the other hand, community pharmacists which are the most accessible healthcare providers by the community increase their awareness regarding the preventive measures, balance medicines supply and demand, provide drive-thru and home delivery services, offer telehealth counselling, psychological support, refer suspected COVID-19 patients, and provide vaccination when available. CONCLUSION: Innovative pharmacists' roles have emerged to adapt to changes during COVID-19 pandemic, however, they may be needed in the post COVID-19 world as well.

RESUMO

INTRODUCTION: Pregnancy period is of high concern to every woman. Knowledge about medication use needs to be highlighted at such a critical stage. OBJECTIVE: This study aimed to assess pregnant and postpartum women's use and attitude regarding the utilisation of medications during pregnancy in the United Arab Emirates (UAE). METHODS: A self-administrated survey was distributed among 500 pregnant and postpartum women randomly selected from the general population of five different cities within the UAE: Abu Dhabi, Dubai, Sharjah, AL Fujairah and Ajman over a period of 3 months. All analyses were two-sided, and a P-value of ≤.05 was taken as the cut-off for statistical significance. RESULTS: Overall, 434 participants took part in the survey. Forty-one percent of respondents reported that they use drugs during pregnancy, and the most frequently used medications during pregnancy were multivitamins, analgesics and folic acid. Moreover, 77.9% of female participants acquired their knowledge from their gynaecologists. Only 21.7% of respondents reported that the pharmacist provided enough information during dispensing. Most ladies had an uplifting mentality towards medicines, but they believed pregnant ladies should be more wary with respect to medication use during pregnancy. A significant association was found between participants' nationality and occupation, and attitudes about medications (P < .001), where women with Arab nationality and those with health-related careers agreed that they have a higher threshold for using medicines during pregnancy. CONCLUSION: During pregnancy, ladies were more moderate and doubter towards the drug, healthcare providers should know about such mentalities while encouraging pregnant ladies to take prescription.

RESUMO

OBJECTIVES: This study aimed to investigate the frequency, nature, and clinical significance of pharmacist interventions on over-the-counter (OTC) medicines with abuse potential across community pharmacies with and without virtual care. METHODS: In this prospective observational study, a trained research team observed the dispensary teams of 12 community pharmacies in the United Arab Emirates (UAE), 6 of which were operating virtual pharmacy care. A standardized data collection form was used to include information about dispensing of OTC medicines and pharmacist interventions on those with abuse/misuse potential. The clinical significance of the interventions was evaluated by a multidisciplinary committee. RESULTS: The frequency of pharmacist interventions on OTC medicines with abuse potential across pharmacies with and without virtual services was 83.2% versus 91.0%, respectively, whereas the frequency of pharmacist interventions on OTC medicines with misuse potential across pharmacies with and without virtual services was 79.8% versus 41.2%, respectively. The proportions of clinically significant interventions across pharmacies with and without virtual services were 19.7% versus 10.5%, respectively. Cough medicines were dispensed significantly more across pharmacies with virtual care than across pharmacies without virtual care (25.6% vs. 9.7%, respectively; P = 0.04). Asking the patient to seek the advice of an addiction specialist (adjusted odds ratio = 4.11; P = 0.001) versus refusing to sell the drug was more likely to be associated with pharmacies with virtual services than with pharmacies operating traditional pharmacy services. CONCLUSION: Virtual pharmaceutical care is a potential approach to reduce the abuse/misuse of OTC medicines but needs some improvements regarding detection of these cases. The UAE is the first country in the region to implement and regulate virtual pharmacy practice.

RESUMO

Background: Telepharmacy services are expected to have an important role in increasing access of patients to pharmaceutical care and reducing potential dispensing errors in community pharmacies. Objective: To assess the predictors for effective telepharmacy services on increasing access of patients to care and reducing dispensing errors in community pharmacies. Method: This is a prospective study carried out for 4 months in 52 community pharmacies across the United Arab Emirates (UAE) using disguised direct observation. Multivariable logistic regression was used as a tool to predict factors associated with effective telepharmacy services in improving dispensing safety and increasing access of patients to pharmaceutical care. Data were entered and analyzed using the Statistical Package for Social Science (SPSS) software version 26. Results: Pharmacist recommendations related to COVID-19 at pharmacies with telepharmacy (n = 63,714) versus those without remote services (n = 15,539) were significantly more likely to be (1) contact the nearest testing center (adjusted odds ratio [AOR] = 7.93), (2) maintain home quarantine (AOR = 5.64), and (3) take paracetamol for fever (AOR = 3.53), all were significant results (p < 0.05). Rates of medication dispensing errors (MDEs) and its subcategories, prescription-related errors, and pharmacist counseling errors across pharmacies with telepharmacy versus those without remote services were (15.81% vs. 19.43%, p < 0.05), (5.38% vs. 10.08%, p < 0.05), and (10.42% vs. 9.35%, p > 0.05), respectively. However, pharmacies with telepharmacy were more likely to include wrong patient errors (AOR = 5.38, p < 0.05). Conclusions: Telepharmacy can be used as a tool to reduce the burden on the health care system and improve drug dispensing safety in community pharmacies.

RESUMO

Iodine is a micronutrient essential for normal thyroid function, growth and development of a child. Iodine deficiency remains an unresolved problem worldwide, where even in countries with adequate iodine supply certain population groups remain particularly at risk. Premature newborns comprise one such group as several factors including organic and functional developmental immaturity, a lower iodine reserve pool and insufficient postnatal iodine intake may contribute to iodine deficiency. However, such newborns are also more susceptible to autoregulatory thyroid inhibition upon excessive iodine supply. Several guidelines on the optimal daily iodine intake for preterm newborns exist in different parts of the world. Our article presents an overview of these guidelines and current data about iodine content in parenteral nutrition, breast milk and milk formulas.

RESUMO

INTRODUCTION: Mental illness has become a global public health issue and according to WHO report in 2015, United Arab Emirates (UAE) recorded the highest level of depression among all countries at Eastern Mediterranean Region. Many people frequently suffer from mental health diseases but tend not to obtain help. Treatment delay can become life-threatening. OBJECTIVES: This study aimed to identify the barriers to seeking professional help for mental illness and the consequences of untreated mental health disorders. The study also aimed to examine outcomes in patients when help was provided by health care providers. METHODS: A self-administrated survey was distributed among 377 people randomly selected from general population of three different cities at United Arab Emirates (UAE): Abu Dhabi, Dubai and Sharjah. Their perception of the barriers, consequences and outcomes was analyzed to achieve the objectives of the study. RESULTS: Overall, 341 participants completed the survey. Wrong thought regarding mental disorders (60.1%) and being ashamed (58.9%) were identified to be the most common and significant barriers (P < 0.001) that prevent people from obtaining healthcare providers' assistance. The majority of responders reported building confidence (78.9%) and improvement in relationships (73.0%) as outcomes for taking professional help in mental illness. Moreover, many individuals believed that untreated mental illness could lead to problems with family and friends (69.2%) as well as to suicidal thoughts (56.3%). CONCLUSION: This research gives some insights regarding the challenges associated with mental diseases management in the UAE. Majority of responders had a negative perception of mental health service due to a lack of awareness regarding treatment effectiveness for mental disorders.

RESUMO

Paraduodenal hernias (PDH) pose a diagnostic challenge due to their varied presentations and rarity. We report a rare case report illustrating the clinical course, diagnostic approach, and management of PDH in a 19-year-old female patient with a history of neonatal laparotomy for intestinal atresia. The patient initially presented with chronic, diffuse abdominal pain, which had progressively worsened over 2 years. Physical examination revealed no palpable mass, with normal bowel sounds and vital signs. Imaging studies, including computed tomography of the abdomen, demonstrated protrusion of small bowel loops in the left upper abdominal quadrant consistent with a left paraduodenal hernia. Following laparoscopic exploration, a large defect was identified, and successful repair was performed, resulting in resolution of symptoms and a smooth postoperative recovery. Our case highlights the importance of maintaining a high index of suspicion for PDH in patients with chronic abdominal pain, particularly those with a history of abdominal surgeries. Prompt diagnosis and timely surgical intervention, preferably laparoscopic, can lead to favorable outcomes and improved quality of life for affected individuals.

RESUMO

INTRODUCTION: Esophageal cancer, notably rare in the proximal esophagus, demonstrates poor outcomes despite advanced treatments. This case underscores the successful management of proximal esophageal adenocarcinoma using chemoradiotherapy alone. CASE PRESENTATION: A 65-year-old Mediterranean woman presented with severe dysphagia and was diagnosed with stage IVA T4b N0M0 esophageal adenocarcinoma. She achieved complete remission after chemoradiotherapy, evidenced by PET CT scans, without surgical intervention. DISCUSSION: This case highlights the rarity of proximal esophageal adenocarcinoma and challenges the conventional treatment paradigm, emphasizing the potential of chemoradiotherapy as a standalone treatment in selected advanced cases. CONCLUSION: The complete response to chemoradiotherapy in this case of proximal esophageal adenocarcinoma illustrates the need for personalized treatment strategies and further research into non-surgical options for esophageal cancer management.

RESUMO

BACKGROUND: Fabaceae plays a crucial role in African traditional medicine as a source of large number of important folk medication, agriculture and food plants. In a search of potential antioxidant and anti-inflammatory candidates derived from locally cultivated plants, the flowers of Tipuana tipu (Benth.) Lillo growing in Egypt were subjected to extensive biological and phytochemical studies. The impact of the extraction technique on the estimated biological activities was investigated. METHODS: The flowers were extracted using different solvents (aqueous, methanol, water/methanol (1:1), methanol/methylene chloride (1:1), and methylene chloride). The different extracts were subjected to antioxidant (DPPH, ABTS, and FRAP) and anti-inflammatory (COX-2 and 5-LOX) assays. The methanol extract was assessed for its inhibitory activity against iNOS, NO production, and pro-inflammatory cytokines (NF-KB, TNF-R2, TNF-α, IL-1ß, and IL-6) in LPS-activated RAW 264.7 macrophages. The composition-activity relationship of the active methanol extract was further investigated using a comprehensive LC-QTOF-MS/MS analysis. The major identified phenolic compounds were further quantified using HPLC-DAD technique. The affinity of representative compounds to iNOS, COX-2, and 5-LOX target active sites was investigated using molecular docking and molecular dynamics simulations. RESULTS: The methanol extract exhibited the highest radical scavenging capacity and enzyme inhibitory activities against COX-2 and 5-LOX enzymes with IC50 values of 10.6 ± 0.4 and 14.4 ± 1.0 µg/mL, respectively. It also inhibited iNOS enzyme activity, suppressed NO production, and decreased the secretion of pro-inflammatory cytokines. In total, 62 compounds were identified in the extract including flavonoids, coumarins, organic, phenolic, and fatty acids. Among them 18 phenolic compounds were quantified by HPLC-DAD. The highest docking scores were achieved by kaempferol-3-glucoside and orientin. Additionally, molecular dynamics simulations supported the docking findings. CONCLUSION: The flower could be considered a potentially valuable component in herbal medicines owing to its unique composition and promising bioactivities. These findings encourage increased propagation of T. tipu or even tissue culturing of its flowers for bioprospecting of novel anti-inflammatory drugs. Such applications could be adopted as future approaches that benefit the biomedical field.

RESUMO

This study comprehensively analyzes the primary metabolites of sweet potato peels and pulps from four cultivars and assesses the impact of four different processing methods on pulp metabolome using a multiplex metabolomics approach of GC-MS and NIR. A total of 69 metabolites were identified. Beauregard cv. showed the highest sugar content (387.85 mg/g), whereas Sahrawy cv. was higher in alcohols (24.63 mg/g) and organic acids (2.98 mg/g). The chemometric analysis identified key markers that distinguished each cv. represented by its pulp, peel, and processed pulp. KEGG enrichment analysis pinpointed key metabolic pathways leading to the metabolic discrepancy of the specimens. Sugars were the most altered class by processing as manifested by a 5 to 11-fold increase, notably in the air-fried pulp. Air-frying also increased alcohol and organic acid contents. NIR analysis revealed that air-frying was the preferred method of processing, preserving the majority of pulp's metabolites, including ß-carotene and phenolics.

RESUMO

Even though legumes are valuable medicinal plants with edible seeds that are extensively consumed worldwide, there is little information available on the metabolic variations between different dietary beans and their influence as potential anti-cholinesterase agents. High-resolution liquid chromatography coupled with mass spectrometry in positive and negative ionization modes combined with multivariate analysis were used to explore differences in the metabolic profiles of five commonly edible seeds, fava bean, black-eyed pea, kidney bean, red lentil, and chickpea. A total of 139 metabolites from various classes were identified including saponins, alkaloids, phenolic acids, iridoids, and terpenes. Chickpea showed the highest antioxidant and anti-cholinesterase effects, followed by kidney beans. Supervised and unsupervised chemometric analysis determined that species could be distinguished by their different discriminatory metabolites. The major metabolic pathways in legumes were also studied. Glycerophospholipid metabolism was the most significantly enriched KEGG pathway. Pearson's correlation analysis pinpointed 18 metabolites that were positively correlated with the anti-cholinesterase activity. Molecular docking of the biomarkers to the active sites of acetyl- and butyryl-cholinesterase enzymes revealed promising binding scores, validating the correlation results. The present study will add to the metabolomic analysis of legumes and their nutritional value and advocate their inclusion in anti-Alzheimer's formulations.

RESUMO

BACKGROUND: Infections caused by Acinetobacter baumannii are becoming a rising public health problem due to its high degree of acquired and intrinsic resistance mechanisms. Bacterial lipases penetrate and damage host tissues, resulting in multiple infections. Because there are very few effective inhibitors of bacterial lipases, new alternatives for treating A. baumannii infections are urgently needed. In recent years, Brassica vegetables have received a lot of attention since their phytochemical compounds have been directly linked to diverse antimicrobial actions by inhibiting the growth of various Gram-positive and Gram-negative bacteria, yeast, and fungi. Despite their longstanding antibacterial history, there is currently a lack of scientific evidence to support their role in the management of infections caused by the nosocomial bacterium, A. baumannii. This study aimed to address this gap in knowledge by examining the antibacterial and lipase inhibitory effects of six commonly consumed Brassica greens, Chinese cabbage (CC), curly and Tuscan kale (CK and TK), red and green Pak choi (RP and GP), and Brussels sprouts (BR), against A. baumannii in relation to their chemical profiles. METHODS: The secondary metabolites of the six extracts were identified using LC-QTOF-MS/MS analysis, and they were subsequently correlated with the lipase inhibitory activity using multivariate data analysis and molecular docking. RESULTS: In total, 99 metabolites from various chemical classes were identified in the extracts. Hierarchical cluster analysis (HCA) and principal component analysis (PCA) revealed the chemical similarities and variabilities among the specimens, with glucosinolates and phenolic compounds being the major metabolites. RP and GP showed the highest antibacterial activity against A. baumannii, followed by CK. Additionally, four species showed a significant effect on the bacterial growth curves and demonstrated relevant inhibition of A. baumannii lipolytic activity. CK showed the greatest inhibition (26%), followed by RP (21%), GP (21%), and TK (15%). Orthogonal partial least squares-discriminant analysis (OPLS-DA) pinpointed 9 metabolites positively correlated with the observed bioactivities. Further, the biomarkers displayed good binding affinities towards lipase active sites ranging from -70.61 to -30.91 kcal/mol, compared to orlistat. CONCLUSION: This study emphasizes the significance of Brassica vegetables as a novel natural source of potential inhibitors of lipase from A. baumannii.

RESUMO

Objectives: Schizophrenia, unipolar depression, bipolar disorder, bipolar mania, and bipolar depression are a few of the severe psychiatric diseases that affect millions of individuals and their overall life quality. This study aimed to look at differences in TGA, TC, HDL, LDL, and FPG levels in people who were going through acute episodes of listed diseases. Materials and methods: A cross-sectional prospective study was carried out in Jordan between January and November of 2023, involving all patients with the aforementioned diseases who attended three psychiatric clinics. This study encompassed results from 1187 patients (women N = 675, 56.87%) who were classified into the following ranges: <25, 25-45, 45-65, and >65. Results: The average level of LDL was the highest in bipolar depression (112.442 ± 36.178 mg/dL) and the lowest in bipolar mania (111.25 ± 33.14 mg/dL). The average level of HDL was the highest in schizophrenia (58.755 ± 16.198 mg/dL) and the lowest in bipolar depression (45.584 ± 12.128 mg/dL). Both average levels of TC and TGA were the highest in patients with bipolar depression (188.403 ± 37.396 mg/dL and 149.685 ± 96.951 mg/dL, respectively) and the lowest in bipolar mania (164.790 ± 40.488 mg/dL and 100.679 ± 54.337 mg/dL, respectively). The average level of FPG was the highest in unipolar depression (94.00 ± 21.453 mg/dL) and the lowest in bipolar mania (89.492 ± 14.700 mg/dL). Conclusions: The results confirmed that lipid and glucose abnormalities were more common in people with schizophrenia and mood disorders (unipolar and bipolar).

RESUMO

Injuries to the peripheral nervous system are a common clinical issue, causing dysfunctions of the motor and sensory systems. Surgical interventions such as nerve autografting are necessary to repair damaged nerves. Even with autografting, i.e., the gold standard, malfunctioning and mismatches between the injured and donor nerves often lead to unwanted failure. Thus, there is an urgent need for a new intervention in clinical practice to achieve full functional recovery. Nerve guidance conduits (NGCs), providing physicochemical cues to guide neural regeneration, have great potential for the clinical regeneration of peripheral nerves. Typically, NGCs are tubular structures with various configurations to create a microenvironment that induces the oriented and accelerated growth of axons and promotes neuron cell migration and tissue maturation within the injured tissue. Once the native neural environment is better understood, ideal NGCs should maximally recapitulate those key physiological attributes for better neural regeneration. Indeed, NGC design has evolved from solely physical guidance to biochemical stimulation. NGC fabrication requires fundamental considerations of distinct nerve structures, the associated extracellular compositions (extracellular matrices, growth factors, and cytokines), cellular components, and advanced fabrication technologies that can mimic the structure and morphology of native extracellular matrices. Thus, this review mainly summarizes the recent advances in the state-of-the-art NGCs in terms of biomaterial innovations, structural design, and advanced fabrication technologies and provides an in-depth discussion of cellular responses (adhesion, spreading, and alignment) to such biomimetic cues for neural regeneration and repair.

RESUMO

Sickle cell anemia is a chronic and debilitating hemoglobinopathy characterized by the presence of abnormal hemoglobin, resulting in the formation of sickle-shaped red blood cells. This case report presents an unusual case of a 32-year-old female patient with sickle cell anemia who had not experienced any previous sickle cell crises since her diagnosis at the age of four years. Despite a stable clinical history, the patient's condition rapidly deteriorated, leading to septic shock, multiorgan failure, and atypical complications such as neurological impairment and acute kidney injury. Intensive management strategies, including blood exchange, mechanical ventilation, and aggressive antibiotic therapy, were implemented but unfortunately failed to reverse the progressive clinical deterioration. This case underscores the importance of early recognition and a multidisciplinary approach in managing atypical sickle cell crises to optimize patient outcomes. Further research is needed to improve our understanding and management of such presentations.

RESUMO

This paper presents a novel approach to utilizing agricultural waste. It compares three different applications for cotton stalks: fabrication of wood composites, bioethanol production, and biogas cradle-to-gate Life cycle assessment production processes. Cotton cultivation generates a lot of debris, mostly cotton stalks, which are incinerated or landfilled, Sustainable resource management is critical for maintaining the ecosystem, and economic stability, and promoting social fairness since it ensures the long-term availability of resources while minimizing environmental damage. The investigation uses the Ecological Footprint, Impact 2002 +, Global Warming Damage Potential, Greenhouse Gas Protocol, Recipe Midpoint, Ecosystem Damage Potential, and CML IA Baseline-open LCA-enabled environmental sustainability assessments. The analysis showed that bioethanol has a lower carbon footprint and climate change impact than both wood composite and biogas production processes, as a result, this could cause a preference for bioethanol production as an environmentally friendly strategy for cotton stalks utilization. While human toxicity was higher in the biogas production process, it emits less fossil CO2 than biogenic CO2. The total climate change of wood composite, bioethanol, and biogas production processes was 0.01761, 0.011300, and 0.01083 points, respectively. This research helps accomplish wider ecological and economic aims by giving insights into sustainable waste management practices.
