Fungi generate different metabolites some of which are intrinsically bioactive and could therefore serve as templates for drug development. In the current study, six endophytic fungi namely Aspergillus flavus, Aspergillus tubigenesis, Aspergillus oryzae, Penicillium oxalicum, Aspergillus niger, and Aspergillus brasiliensis were isolated and identified from the medicinal plant, Silybum marianum. These endophytic fungi were identified through intra transcribed sequence (ITS) gene sequencing. The bioactive potentials of fungal extracts were investigated using several bioassays such as antibacterial activity by well-diffusion, MIC, MBC, anti-biofilm, antioxidant, and haemolysis. The Pseudomonas aeruginosa PAO1 was used to determine the antibiofilm activity. The ethyl acetate extract of Aspergillus flavus showed strong to moderate efficacy against Staphylococcus aureus, Escherichia coli, P. aeruginosa, and Bacillus spizizenii. Aspergillus flavus and Aspergillus brasiliensis exhibited significant antibiofilm activity with IC50 at 4.02 and 3.63 mg/ml, while A. flavus exhibited maximum antioxidant activity of 50.8%. Based on HPLC, LC-MS, and NMR experiments kojic acid (1) and carbamic acid (methylene-4, 1-phenylene) bis-dimethyl ester (2) were identified from A. flavus. Kojic acid exhibited DPPH free radical scavenging activity with an IC50 value of 99.3 µg/ml and moderate activity against ovarian teratocarcinoma (CH1), colon carcinoma (SW480), and non-small cell lung cancer (A549) cell lines. These findings suggest that endophytic fungi are able to produce promising bioactive compounds which deserve further investigation.

In the dynamic landscape of Breast Cancer (BC), Oligo- Metastatic Breast Cancer (OMBC) presents unique challenges and opportunities. This comprehensive review delves into current strategies for addressing OMBC, covering locoregional and site-specific metastasis management, and addressing both surgical and minimally invasive therapies as essential components. Moreover, the transformative role of Artificial Intelligence (AI) is spotlighted. However, while the future looks promising, several limitations need addressing, including the need for further research, especially in diverse patient populations and resource-challenged settings. AI implementation may require overcoming the lack of Electronic Health Records acceptance in resource-challenged countries, which contributes to a scarcity of large datasets for AI training. As AI continues to evolve, validation and regulatory aspects must be continually addressed for seamless integration into clinical practice. In summary, this review outlines the evolving landscape of OMBC management, emphasizing the need for comprehensive research, global collaboration, and innovative AI solutions to enhance patient care and outcomes.

The control of infections is one of the key strategies to treat cuts, wounds, lung, and skin infections. In this study the folkloric use of Rumex dentatus (R. dentatus) roots in the mentioned conditions was scientifically investigated. The methanolic (MeOH) crude extract of R. dentatus root was fractionated (n-hexane, ethyl acetate and water) via bioassay-guided method, and its antibacterial activity was evaluated using the agar well diffusion and Minimum inhibitory concentration (MIC) assays against clinical isolate of Pseudomonas aeruginosa (P. aeruginosa). The antibiofilm activity was measured using the crystal violet staining method. The crude extract, fractions and sub-fractions tested showed the MICs values ranging from 200 to 1000 µg/mL respectively. Among the fractions, notably, the water fraction exhibited the highest activity against P. aeruginosa. The water fraction was then subjected to thin layer chromatography (TLC). Following spectrometric analysis using HPLC-ESI-Q-TOF-MS, gallic acid and emodin were identified as the primary components within the same fraction, responsible for eliciting antibacterial and antibiofilm effects. The in-silico studies conducted with AutoDock Vina on the LasR protein, using both isolated gallic acid and emodin, confirm the binding affinity of these molecules to the active sites of the LasR protein that has regulatory role in building of biofilm formation and its pathogenicity. By scientifically validating the infection-controlling properties of R. dentatus, this research provides compelling evidence that supports its traditional use as reported in folklore. Moreover, this study contributes to our understanding of the plant's potential in managing infections, thereby substantiating its traditional therapeutic application in a scientific context.
RESUMEN
Parsley (Petroselinum crispum) is herb with many biological and medicinal benefits for humans. However, growth on zinc (Zn) and cadmium (Cd) contaminated sites might get severely affected due to over accumulation of heavy metals (HM) in different plant tissues. Antioxidants play a crucial role in minimizing the negative effects of HM. The present study investigates the effects of Zn and Cd stress on P. crispum morphological parameters, enzymatic/non-enzymatic antioxidant profiling and metal accumulation in shoot/root. Plants were exposed to different concentrations of Zn (50, 100, 150 and 200 µM) and Cd (10, 20, 40 and 80 µM) along with control (no stress), in soil-less Hoagland's solution. The results showed that Zn and Cd substantially decrease the growth parameters with increased contents of malondialdehyde (MDA), hydrogen peroxide (H2O2), and electrolyte leakage (EL). Non-enzymatic antioxidant activities, like total phenolic contents (TPC) and ferric reducing antioxidant power (FRAP), were induced high in leaves only upon Cd stress and contrarily decreased upon Zn stress. Total flavonoid contents (TFC) were decreased under Zn and Cd stress. Enzymatic antioxidant activities like superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) were also strongly induced upon Cd stress. At the same time, SOD and guaiacol peroxidase (GPX) activity was induced significantly upon Zn stress. Cd uptake and accumulation was notably high in roots as compared to shoots, which suggests P. crispum have a reduced ability to translocate Cd towards aboveground parts (leaves). Additionally, strong induction of antioxidants by P. crispum under Cd stress might indicate the capacity to effectively re-modulate its physiological response. However, further investigations regarding other HMs and experiments at the molecular level are still needed.

INTRODUCTION: Fumarate Hydratase-deficient-renal cell carcinoma (FH-dRCC) is an uncommon and extremely aggressive variant of renal cell carcinoma (RCC) resulting from inactivating mutations in the tumor suppressor gene, fumarate hydratase (FH). CASE PRESENTATION: We report a case of a young male who presented with the complaint of painless hematuria. Upon workup, he was found to have a renal mass with bony metastases. The histopathology was consistent with renal cell carcinoma with features of FH-deficient variant. Germline testing showed a pathogenic mutation in the FH gene. He was started on a treatment combination of Pembrolizumab and Axitinib along with Zoledronate for bone metastasis. His response to the combination therapy was short with early progression of disease. He was switched to a second-line treatment Bevacizumab and Erlotinib, which achieved significant disease response. DISCUSSION: Systemic therapy is the mainstay of treatment for metastatic disease. Although the novel agents approved for other subsets of RCC have been used, the responses are grim. There is no consensus on the sequence of further lines of treatment for FH-dRCC and is based on the physician's choice, availability of the drugs, cost, toxicity, and tolerance of the patient. CONCLUSION: This case report emphasizes the occurrence, presentation, management and prognosis of FH-dRCC, which is an aggressive entity, presenting at a young age with early distant metastases, not diagnosed appropriately due to its poorly characterized cytologic features. Being an infrequent neoplasm, it is an area that warrants oncological exploration to improve outcomes in these individuals. The combination of Erlotinib and Bevacizumab provides promising outcomes in terms of progression-free survival.
RESUMEN
This comprehensive narrative review aims to investigate the impact of virtual reality (VR) and social gaming on the quality of life, depression, and dialysis tolerance in patients with chronic kidney disease (CKD), a growing global health concern affecting the quality of life and increasing mortality rates. Through a combination of exercise and video games, exergaming, and digital game therapy (DGT), sedentary risks can be mitigated and therapy adherence enhanced. Despite potential side effects such as exhaustion and nausea, research indicates that virtual therapeutic games improve motivation and dialysis tolerance, and even reduce brain activity in pain-associated regions during procedures. These methods are superior to traditional distraction techniques like music, movies, and toys. Exergaming, social gaming, and VR gaming can improve various health factors including depressive symptoms, functional capacity, muscle strength, fatigue, physical activity, mental health, motivation, engagement, cognition, and overall quality of life for CKD patients. Representing a novel approach to CKD management, these interventions promote physical activity, cognitive stimulation, and social interaction. Continued research and innovation will facilitate the integration of VR-based therapies into routine CKD care.
RESUMEN
BACKGROUND: Vascularized (VBG) and non-vascularized (NVBG) bone grafting are two crucial biological reconstructive techniques in the management of bone tumours. The objective of this study is to compare the outcomes of reconstruction with vascularized and non-vascularized bone grafts after resection of bone tumours. METHODS: A systematic evaluation of the literature from 2012-2021 was undertaken using the online databases PubMed/Medline, Google Scholar, and Cochrane Library considering only comparative articles with specific outcomes for the restoration of the defect with vascularized and non-vascularized bone graft following the resection of bone tumours. The quality of the research methodology was evaluated using Oxford Quality Scoring System and Newcastle Ottawa Scale for randomized trials and non-randomized comparison research respectively. The SPSS version 23 was used to examine the data that was collected. Musculoskeletal tumour society score (MSTS), bone union time, and complications were the outcomes of this review. RESULTS: Four clinical publications were considered, totalling 178 participants (92 men and 86 women) with 90 patients with VBG and 88 with NVBG. MSTS score and bone union time were the key outcomes that were measured. The overall MSTS (p>0.05) and rate of complications (p>0.05) results were comparable between the two groups, however, VBG had a better rate of bone union (p<0.001). CONCLUSIONS: As a result of the quicker bone union, our systematic evaluation demonstrated that VBG causes earlier recovery. Complication rates and functional results were the same in both groups. The link between the bone union time and functional score following VBG and NVBG must also be demonstrated.

Neurogenic orthostatic hypotension (nOH) is a disabling problem of autonomic dysfunction in patients with Parkinson's disease, which is associated with poor quality of life and higher mortality rates. The purpose of this literature review was to explore and compare the efficacy and safety of droxidopa (an existing treatment) and ampreloxetine (a newer medication) in the treatment of nOH. We used a mixed-method literature review that addresses the epidemiology, pathophysiology, and pharmacological and non-pharmacological management of nOH in Parkinson's disease in a general way, with a more exploratory approach to droxidopa- and ampreloxetine-controlled trial studies. We included a total of 10 studies of randomized controlled trials with eight studies focused on droxidopa and two studies focused on ampreloxetine. These two drugs were analyzed and compared based on the collected individual study results. Treatment of nOH in Parkinson's disease patients with droxidopa or ampreloxetine showed clinically meaningful and statistically significant improvements relative to placebo on the components of the OHSA (Orthostatic Hypotension Symptom Assessment) composite score and OHDAS (Orthostatic Hypotension Daily Activity Scale composite scores) composite score. Droxidopa had an improved effect on daily activities, with an associated increase in standing systolic blood pressure (BP), but the long-term efficacy of droxidopa has not been documented. Standing systolic BP was maintained by ampreloxetine and worsened after the withdrawal phase. This highlights the importance of conducting further research which will help us to improve the therapeutic approach for patients with nOH and Parkinson's disease.
RESUMEN
Ventilator-associated pneumonia (VAP) is the most common ICU acquired pneumonia among patients who are invasively intubated for mechanical ventilation. Patients with VAP suffer an increased mortality risk, financial burden, and length of stay in the hospital. The authors aimed to review the literature to describe the incidence, mortality, and microbiological evidence of VAP. We selected 13 peer-reviewed articles published from 1 January 2010 to 15 September 2022 from electronic databases for studies among adult or pediatric patients diagnosed with VAP expressed per thousand days admitted in the ICU. The VAP rates ranged from 7 to 43 per thousand days, varying among different countries of the world. A significant rate of mortality was observed in 13 studies ranging from 6.3 to 66.9%. Gram-negative organisms like Acinetobacter spp., Pseudomonas aeruginosa Gram-positive organisms like Staphylococcus aureus were frequently found. Our findings suggest an alarming situation of VAP among patients admitted to the intensive care units with increasing incidence and mortality. The review also found that VAP is more common in males and that there is a significant variation in the incidence and mortality rates of VAP among different countries. The findings of this review can inform the development of infection control and prevention strategies to reduce the burden of VAP. Thus, there is a crucial need for control and preventive measures like interventional studies and educational programs on staff training, hand-hygiene, and the appropriate use of ventilator bundle approach to curb this preventable threat that is increasing at an alarming rate.
RESUMEN
Background Pakistan's hereditary breast cancer has a higher-than-average prevalence. Our acceptability of prophylactic risk-reducing mastectomy (PRRM) still needs to be determined, and genetic testing still needs to be offered to all eligible. The aim is to determine the number of women presenting to our centre who availed of PRRM after positive genetic tests and the main reasons restraining them from considering PRRM.Materials and methods This study is a single-centre, prospective cohort. We collected data from 2017 to 2022 on BRCA1/2 and other (P/LP) gene-positive patients. Continuous variables are presented as means (±SD) and categorical variables in percentages, with a significant P-value of ≤ 0.05.Results Out of 477 tested individuals, only 95(20.12%) had a positive result. BRCA1/2 was positive in 70 cases, while P/LP variants were in 24 cases. Only 32.6% of eligible families underwent genetic testing, with 54.8% positivity. Altogether, 92.6% of patients had BRCA1/2-related cancers. Only 25/95(26.3%) individuals availed of PRRM, the majority had contralateral risk-reducing mastectomy 68% with a 20% reconstruction rate. The main reasons to decline PRRM were false belief of not having any disease 57.44%, followed by family/spouse pressure 51%, body appearance/societal perception, fear of complications/quality of life and financial constraints.Conclusion Genetic testing and its implications are still a grey area for LMICs, primarily due to the scarcity of centres offering genetic testing to eligible populations, followed by prevalent perceptions about prophylactic surgeries among the masses. Addressing relevant issues in LMICs is the need of time.

INTRODUCTION: Adenoid cystic carcinoma is a neoplasm that is commonly of salivary gland origin. It could infrequently arise from other tissues such as breast in which case it behaves favorably despite belonging to triple-negative breast cancer subgroup. CASE PRESENTATION: We report a case of a 49-year-old female patient, who presented with right breast pain and upon work-up, was diagnosed with early-stage adenoid cystic carcinoma of the breast. She underwent breast conservation successfully and was advised to get evaluated for adjuvant radiotherapy. The work has been reported in line with the SCARE criteria (Agha et al., 2020). CLINICAL DISCUSSION: Breast adenoid cystic carcinoma (BACC) is a rare distinct salivary gland-like carcinoma of the breast with similar morphological features to those seen in salivary gland adenoid cystic carcinoma. Surgical resection is the standard mode of treatment in BACC. The role of adjuvant chemotherapy has not proven beneficial in the management of BACC, owing to the similar survival rates seen in patients with and without chemotherapy. CONCLUSION: Localized breast adenoid cystic carcinoma (BACC) is an indolent disease having optimal response to surgical resection alone and thus can omit adjuvant radiotherapy and chemotherapy when completely excised. Our case is unique as BACC is a rare clinical variant of breast cancer with a very low incidence rate.
RESUMEN
Breast Cancer Stem Cells (BCSCs), unlike normal breast cells, exhibit the potential for self-regeneration and tumour formation and express unique markers. Studies have highlighted their role in tumour progression, recurrence, and treatment resistance. BCSCs can be one of the reasons that resistance is encountered despite recent advances in the treatment of breast cancer (BC). This review underlines the clinical implications at the molecular level of different cellular pathways, cellular level interactions in Tumour Micro Environment (TME), and types of markers and receptors involved in tumorigenesis. It accentuates the importance of comprehensive targeted treatment options available for BCSCs so that targeted modalities can be introduced to deal with treatment resistance. Stem cells (SCs) are a developing field, and limited data is available from our country to use stem cell-targeted treatment plans as a therapeutic option. Therefore, this literature review will provide insight for future research in this domain.

Series of sulfonamide-substituted amide (9-11), benzamide (12-15), and 1,3-disubstituted thiourea (17-26) derivatives were synthesized from a common precursor, i.e., substituted benzoyl chlorides. Structures of all of the synthesized compounds were characterized by spectroscopic techniques (1H nuclear magnetic resonance (NMR),13C NMR, and Fourier transform infrared spectroscopy (FTIR)). All of the amide (9-15) and thiourea (17-26) derivatives were screened against human carbonic anhydrases, hCA-II, hCA IX, and hCA-XII. Sulfonamide-substituted amides 9, 11, and 12 were found to be excellent selective inhibitors with IC50 values of 0.18 ± 0.05, 0.17 ± 0.05, and 0.58 ± 0.05 µM against hCA II, hCA IX, and hCA XII, respectively. Compound 9 was found to be highly selective for hCA II and about 6-fold more potent as compared to the standard antagonist, acetazolamide. Safe toxicity profiling of the most potent and selective compounds was determined against normal BHK-21 and HEK-293 T cells. Molecular docking studies were performed, which described the type of interactions between the synthesized compounds and enzyme proteins. In addition, in silico absorption, distribution, metabolism, and excretion (ADME) studies were performed, which showed that all of the synthesized molecules fulfilled the druggability criteria.
RESUMEN
Background: Breast cancer, a leading cause of mortality among females, has been the center of research for many decades. Work is in progress to advance the research worldwide and in our region. This study is conducted to look into regional ethical predilection/age, clinical presentation/stage, pathological subtypes and risk factors of BC among patients of Karachi, with the aim of proposing a ground in our policy making regarding protocol setting for screening and management of BC patients. Methods: A prospective cohort study started at public Hospital, Karachi from 2010 to 2020.500 females with histo-pathologically proven BC selected. History, clinical examination, radiological and histo-pathological data retrieved; data regarding age, ethnicity, family history, parity, marriage/menopause, stage/lump size/symptoms were filled on pro-forma. Primary outcomes were age, ethnicity, family history, stage/histological type and menopausal status of our cohort while secondary outcomes were parity, marriage, symptoms and lump size/site. Data analyzed using SPSS in ranges and percentages. Results: Among different ethnicities, Makrani were the most affected(34%). Majority were premenopausal females ≤50yrs (78%). Infiltrating ductal carcinoma (88.8%) was the commonest subtype. Family history was positive in few (5.8%). Parity and marital status had no effect on our population. Breast lump (88%) was the commonest presenting symptom and 51% of our patients had the right side involved. Upper outer quadrant (51%) was the most involved quadrant and the majority (46%) were stage II. Conclusions: Age of presentation is around a decade earlier in our region, with women of Makrani descent more prone to develop BC. 2/3rd of patients were premenopausal, with lump breast as primary complaint. Majority of patients presented in stage-II. Results of age and racial predilection in our population suggest us to concentrate future research more on genetic profiling so we incorporate the results to devise population specific protocols with reference to age, presentation, BC type, ethnicity & risk factors.Record submitted retrospectively at ClinicalTrials.govt on 09-07-2022 NCT05458570 .
RESUMEN
Meckel's diverticulum (MD)1, the most common congenital anomaly of the gastrointestinal tract, occurs in 2% of the population with males being more symptomatic than females. In this case, a 32-year-old male presented with sudden onset colicky abdominal pain, bilious vomiting, and absolute constipation. Emergency laparotomy was done on his virgin abdomen, as a result MD and vitelline cyst along with a fibrous cord connecting the two were identified. Knotting of an ileal loop around this cord had resulted in intestinal obstruction. Meckel's diverticulectomy, along with cord resection, was carried out. The patient made smooth recovery and was discharged on the fifth postoperative day with no complications. The importance of this study is to highlight the case of symptomatic MD in an adult male as it can be a cause of intestinal obstruction and should always be considered in a patient presenting with symptoms of intestinal obstruction.

Critically ill COVID-19 patients have to undergo positive pressure ventilation, a non-physiological and invasive intervention that can be lifesaving in severe ARDS. Similar to any other intervention, it has its pros and cons. Despite following Lung Protective Ventilation (LPV), some of the complications are frequently reported in these critically ill patients and significantly impact overall mortality. The complications related to invasive mechanical ventilation (IMV) in critically ill COVID-19 patients can be broadly divided into pulmonary and non-pulmonary. Among pulmonary complications, the most frequent is ventilator-associated pneumonia. Others are barotrauma, including subcutaneous emphysema, pneumomediastinum, pneumothorax, bullous lesions, cardiopulmonary effects of right ventricular dysfunction, and pulmonary complications mimicking cardiac failure, including pulmonary edema. Tracheal complications, including full-thickness tracheal lesions (FTTLs) and tracheoesophageal fistulas (TEFs) are serious but rare complications. Non-Pulmonary complications include neurological, nephrological, ocular, and oral complications.
