ABSTRACT

Background: The symptoms of gastric outlet obstruction have traditionally been managed surgically or endoscopically. Enteral stenting (ES) is a less invasive endoscopic treatment strategy for this condition. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) has recently become a potential alternative technique. Objectives: We conducted a systematic review and meta-analysis of the effectiveness and safety profile of EUS-GE compared with ES. Design: Meta-analysis and systematic review. Data sources and methods: We searched multiple databases from inception to August 2023 to identify studies that reported the effectiveness and safety of EUS-GE compared with ES. The outcomes of technical success, clinical success, and adverse events (AEs) were evaluated. Pooled proportions were calculated using both fixed and random effects models. Results: We included 13 studies with 1762 patients in our final analysis. The pooled rates of technical success for EUS-GE were 95.59% [95% confidence interval (CI), 94.01-97.44, I 2 = 32] and 97.96% (95% CI, 96.06-99.25, I 2 = 63) for ES. The pooled rate of clinical success for EUS-GE was 93.62% (95% CI, 90.76-95.98, I 2 = 54) while for ES it was lower at 85.57% (95% CI, 79.63-90.63, I 2 = 81). The pooled odds ratio (OR) of clinical success was higher for EUS-GE compared to ES at 2.71 (95% CI, 1.87-3.93). The pooled OR of clinical success for EUS-GE was higher compared to ES at 2.72 (95% CI, 1.86-3.97, I 2 = 0). The pooled rates of re-intervention for EUS-GE were lower at 3.77% (95% CI, 1.77-6.46, I 2 = 44) compared with ES, which was 25.13% (95% CI, 18.96-31.85, I 2 = 69). The pooled OR of the rate of re-intervention in the ES group was higher at 7.96 (95% CI, 4.41-14.38, I 2 = 13). Overall, the pooled rate for AEs for EUS-GE was 8.97% (95% CI, 6.88-11.30, I 2 = 15), whereas that for ES was 19.63% (95% CI, 11.75-28.94, I 2 = 89). Conclusion: EUS-GE and ES are comparable in terms of their technical effectiveness. However, EUS-GE has demonstrated improved clinical effectiveness, a lower need for re-intervention, and a better safety profile compared to ES for palliation of gastric outlet obstruction.

ABSTRACT

Mungbean, Vigna radia (L.) R. Wilczek, is ranked 2nd next to chickpea (Cicer arietinum) in total cultivation and production in Pakistan. In August of 2022 and 2023, mungbean plants (cv. PRI Mung-2018) were found wilting in a field at the Ayub Agricultural Research Institute, Faisalabad, Pakistan. Wilted leaves turned yellow, died, but remained attached to the stem. Vascular tissue at the base of the stem showed light to dark brown discoloration. Roots were stunted with purplish brown to black discoloration. Symptomatic mungbean plants were collected from fields at five different locations (20 samples/location). Disease incidence was similar among the five fields, ranging from 5 to 10% at each location depending upon type of germplasm and date of sowing. For fungal isolation and morphological identification, symptomatic stem and root tissues were cut into ~5 mm2 pieces with a sterilized blade. Tissues were surface-sterilized for one min in a 0.5% sodium hypochlorite solution, rinsed twice in sterilized water, air dried on sterilized filter paper, and aseptically placed on potato dextrose agar (PDA) containing 0.5 g/L-1 streptomycin sulphate. Plates were incubated for 3-4 days at 25 ± 2°C with a 12-h photoperiod. Single-spore cultures were used for morphological and molecular analyses. Isolates on PDA grew rapidly and produced abundant white aerial mycelium that turned off-white to beige with age. Macroconidia were hyaline, falcate, typically 3-to-6 septate with a pointed apical cell and a foot-shaped basal cell, measuring 24.5-49.5 x 2.7-4.7 µm (n = 40). Globose to obovate chlamydospores measuring 5.8 ± 0.5 µm (n = 40) were produced singly or in chains and were intercalary or terminal and possessed roughened walls. The morphological data indicated the isolates were members of the genus Fusarium (Leslie and Summerell 2006). To obtain a species-level identification, a portion of translation elongation factor 1-α (TEF1), the largest subunit of RNA polymerase (RPB1), and the second largest subunit of RNA polymerase (RPB2) region were PCR amplified and sequenced using EF1/EF2 (O'Donnell et al. 1998), Fa/G2R (Hofstetter et al. 2007), and 5f2/7cr (Liu et al. 1999) primers, respectively. DNA sequences of these genes were deposited in GenBank under accession numbers MW059021, MW059017 and MW059019, respectively. The partial TEF1, RPB1 and RPB2 sequences were queried against the Fusarium MLST database (https://fusarium.mycobank.org/page/Fusarium_identification), using the polyphasic identification tool. The BLASTn search revealed 99.9% identity of the isolate to F. nanum (Xia et al. 2019), formerly FIESC 25 of the F. incarnatum-equiseti species complex (MRC 2610, NRRL 54143; O'Donnell et al. 2018). To confirm pathogenicity, roots of 3-5 leaf stage mungbean seedlings were soaked in a 106 spores ml-1 conidial suspension of the fungus for 15 min and then planted in 10 cm pots containing sterilized soil. Mock-inoculated plants with sterile water served as a negative control. Twenty pots that were used for each inoculated and control treatment were maintained at 25 ± 2°C, 14:8 h photoperiod, and 80% relative humidity in a growth chamber. After 15 days, leaf yellowing, internal browning from the base of stems and root discoloration was observed in all the inoculated plants. The uninoculated negative control plants remained asymptomatic. Fusarium nanum was re-isolated from artificially inoculated plants and identified by colony growth, conidial characteristics on PDA and molecular analyses (TEF1). To our knowledge, this is the first report of wilt caused by F.nanum on mungbean in Pakistan. In Pakistan, mungbean cultivation in irrigated areas has increased in recent years. It has been introduced frequently in citrus orchards, crop rotation of maize and sesame, intercropping with sugarcane and as green manure. However, citrus, maize, sesame and sugarcane are also hosts of Fusarium spp. Therefore, this information warrants sustainable crop protection and may have an impact on further interaction of F. nanum with other wilt pathogens.

ABSTRACT

BACKGROUND: Soil salinity is one of the major menaces to food security, particularly in dealing with the food demand of the ever-increasing global population. Production of cereal crops such as wheat is severely affected by soil salinity and improper fertilization. The present study aimed to examine the effect of selected microbes and poultry manure (PM) on seedling emergence, physiology, nutrient uptake, and growth of wheat in saline soil. A pot experiment was carried out in research area of Institute of Soil and Environmental Sciences, University of Agriculture, Faisalabad, Pakistan. Saline soil (12 dS m- 1 w/w) was developed by spiking using sodium chloride, and used in experiment along with two microbial strains (i.e., Alcaligenes faecalis MH-2 and Achromobacter denitrificans MH-6) and PM. Finally, wheat seeds (variety Akbar-2019) were sown in amended and unamended soil, and pots were placed following a completely randomized design. The wheat crop was harvested after 140 days of sowing. RESULTS: The results showed a 10-39% increase (compared to non-saline control) in agronomic, physiological, and nutritive attributes of wheat plants when augmented with PM and microbes. Microbes together with PM significantly enhanced seedling emergence (up to 38%), agronomic (up to 36%), and physiological (up to 33%) in saline soil as compared to their respective unamended control. Moreover, the co-use of microbes and PM also improved soil's physicochemical attributes and enhanced N (i.e., 21.7%-17.1%), P (i.e., 24.1-29.3%), and K (i.e., 28.7%-25.3%) availability to the plant (roots and shoots, respectively). Similarly, the co-use of amendments also lowered the Na+ contents in soil (i.e., up to 62%) as compared to unamended saline control. This is the first study reporting the effects of the co-addition of newly identified salt-tolerant bacterial strains and PM on seedling emergence, physiology, nutrient uptake, and growth of wheat in highly saline soil. CONCLUSION: Our findings suggest that co-using a multi-trait bacterial culture and PM could be an appropriate option for sustainable crop production in salt-affected soil.

ABSTRACT

The field of 2D materials has advanced significantly with the emergence of MBenes, a new material derived from the MAX phases family, a novel class of materials that originates from the MAX phases family. Herein, this article explores the unique characteristics and morphological variations of MBenes, offering a comprehensive overview of their structural evolution. First, the discussion explores the evolutionary period of 2D MBenes associated with the several techniques for synthesizing, modifying, and characterizing MBenes to tailor their structure and enhance their functionality. The focus then shifts to the defect chemistry of MBenes, electronic, catalytic, and photothermal properties which play a crucial role in designing multifunctional solar-driven hybrid systems. Second, the recent advancements and potentials of 2D MBenes in solar-driven hybrid systems e.g. photo-electro catalysis, hybrid solar evaporators for freshwater and thermoelectric generators, and phototherapy, emphasizing their crucial significance in tackling energy and environmental issues, are explored. The study further explores the fundamental principles that regulate the improved photocatalytic and photothermal characteristics of MBenes, highlighting their promise for effective utilization of solar energy and remediation of the environment. The study also thoroughly assesses MBenes' scalability, stability, and cost effectiveness in solar-driven systems. Current insights and future directions allow researchers to utilize MBenes for sustainable and varied applications. This review regarding MBenes will be valuable to early researchers intrigued with synthesizing and utilizing 2D materials for solar-powered water-energy-fuel and phototherapy systems.

ABSTRACT

Radiology has become a fundamental constituent of the modern medicine. However, it has been observed that medical students in Pakistan often lack sufficient guidance and education in this field. This study aims to establish whether Pakistani medical students possess the requisite basic knowledge required in radiology and their attitude and perception toward radiology as a potential career path. This cross-sectional study conducted a survey among 530 medical students of Pakistan via a self-reported online questionnaire from August 01, 2021 to September 01, 2021. The data collected were analyzed using the SPSS software, along with logistic regression analyses to identify factors associated with interest in pursuing radiology as a career and possessing a comprehensive understanding of radiology among medical students. Of the 530 participants, 44.2% rated their understanding of radiology as "poor" with only 17% indicating interest to pursue a career in radiology. Logistic regression model showed significantly higher odds of radiology as a career among males (Crude odds ratio [COR] = 1.78, 95% confidence interval [CI] = 1.17-2.72, P = .007), medical students of Punjab (COR = 1.55, 95% CI = 1.01-2.40, P = .048), and those, who self-reported their knowledge of radiology as excellent (COR = 14.35, 95% CI = 5.13-40.12, P < .001). In contrast, medical students from Punjab (COR = 0.504, 95% CI = 0.344-0.737, P < .001) and second-year medical students (COR = 0.046, 95% CI = 0.019-0.107, P < .001) had lower odds of good knowledge. Our study suggests that the medical student's knowledge of radiology is deficient. Thus, it is advised that radiological societies work with medical school boards to integrate thorough and early radiology exposure into the undergraduate curriculum.

ABSTRACT

BACKGROUND: In severe cases of coronary artery disease, percutaneous coronary intervention provide promising results. The stent used could be a drug-eluting stent (DES) or a titanium-nitride-oxide coated stent (TiNOS). AIM: To compare the 5-year effectiveness and safety of the two stent types. METHODS: The following systematic review and meta-analysis was conducted in accordance with the preferred reporting items for systematic reviews and meta-analysis guidelines, and PubMed/MEDLINE, Scopus, and Cochrane Central were searched from inception till August 2023. Primary outcomes were major adverse cardiac events (MACE), cardiac death, myocardial infarction (MI), cardiac death or MI, and ischemia-driven total lesion revascularization (ID-TLR). RESULTS: Four randomized controlled trials (RCT), which analyzed a sum total of 3045 patients with acute coronary syndrome (ACS) after a median follow-up time of 5 years were included. Though statistically insignificant, an increase in the ID-TLR was observed in patients receiving TiNOSs vs DESs. In addition, MI, cardiac death and MI, and definite stent thrombosis (DST) were significantly decreased in the TiNOS arm. Baseline analysis revealed no significant results with meta-regression presenting non-ST elevated MI (NSTEMI) as a statistically significant covariate in the outcome of MACE. CONCLUSION: TiNOS was found to be superior to DES in terms of MI, cardiac death or MI, and DST outcomes, however, the effect of the two stent types on ID-TLR and MACE was not significant. A greater number of studies are required to establish an accurate comparison of patient outcomes in TiNOS and DES.

ABSTRACT

OBJECTIVE: To analyse the frequency, risk factors, and clinical symptoms of acute graft-versus-host disease (aGvHD) in patients with beta-thalassemia major after allogeneic haematopoietic stem cell transplantation (HSCT). STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Clinical Haematology, Armed Forces Bone Marrow Transplant Centre, Rawalpindi, Pakistan, from January 2017 to December 2021. METHODOLOGY: Data were obtained from patients diagnosed with bone and tissue malignancies (BTM) who had undergone haematopoietic stem cell transplantation (HSCT) and experienced aGVHD. Patients who experienced initial graft failure and individuals who underwent subsequent bone marrow transplantation were excluded. RESULTS: Total of 117 patients diagnosed with BTM underwent fully matched HSCT, including 76 (65%) males, and 41 (35%) females. The median age of the patients undergoing transplantation was 7.34±7.32 years and the donors' median age was 7.6±9.85 years. Among the donors, 53 (45.3%) were males and 64 (54.7%) were females. Gender disparity was observed in 46 (39.3%) instances as a female donor matched with a male recipient. A total of 106 individuals underwent bone marrow harvest (BMH); with 5 (4.3%) patients receiving peripheral blood stem cells (PBSC) and 6 (5.2%) patients receiving both BMH and PBSC. Acute GvHD was observed in 50 (42.7%) patients, including 30 (60%) males and 20 (40%) females. Grade I GvHD occurred in 32 (27.3%) individuals, Grade II GvHD in 16 (13.7%) patients, and Grade III GvHD in one (0.8%) patient. It had no statistically significant association with recipient/donor age, gender disparity, the source of the graft source, the dose of stem cells, or the presence of thymoglobulin (TG). CONCLUSION: Acute GvHD was observed in high frequency in Beta-thalassemia patients receiving morrow harvesting proportional to their gender distribution. Associated factors were GvHD prophylaxis measure, mucositis and, CMV reactivation. KEY WORDS: Beta thalassemia major patients, Acute graft versus host disease, Allogeneic haematopoietic stem cell.

ABSTRACT

Biocomposites developed using natural fibers serve as a sustainable alternative to synthetic composite materials. However, narrowing the performance gap between synthetic composites and biocomposites requires serious efforts. A promising approach is the modification of natural fibers using various chemical treatments. This paper investigates the potential of tannic acid (TA) treatment as a sustainable approach to enhance mechanical performance and reduce moisture absorption of flax fabric-reinforced biocomposites. The methodology involves the treatment of flax woven fabric with tannic acid, a naturally occurring polyphenolic compound, followed by the fabrication of biocomposite using a green epoxy matrix. The variables studied during treatment are TA concentration and processing time. Characterization of untreated and treated flax fabric and its composites was done using various analytical techniques such as FTIR spectroscopy, moisture absorption and mechanical testing (tensile strength, flexural strength, and impact resistance). FTIR spectroscopy of TA-treated flax confirmed attachment of aromatic rings and carbon double bond formation, thus serving for properties enhancement. The mechanical characterization of composites showed that properties are enhanced up to an optimum limit of concentration and processing time i.e., 1 % concentration and 30 min of processing. Moisture absorption of the TA-treated composite also reduced significantly as compared to untreated composites. These findings contribute towards the advancement in sustainable biocomposites and pave the way for their utilization in various applications.

ABSTRACT

The lentil (Lens culinaris Medikus ssp. Culinaris) is a self-pollinating, diploid (2n = 2X = 14) crop with a genome size of 4 Gbp. The present study was conducted to provide a database for the evaluation of lentil antioxidant capacity, nutritional quality, and biochemical attributes. For these purposes, lentil germplasm, including 100 exotic and local genotypes from different agro-climatic zones of Pakistan, was collected. Significant variation (p < 0.05) was found among the genotypes under investigation using the Tukey HSD test. Ascorbate peroxidase was highest in ALTINOPARK (2,465 Units/g s. wt.), catalase in LPP 12110 (5,595 Units/g s. wt.), superoxide dismutase in LPP 12105 (296.75 Units/g s. wt.), and peroxidase in NIAB Masoor 2002 (3,170 Units/g s. wt.). Furthermore, NLM 15016 had a maximum total antioxidant capacity of 15.763 mg/g s. wt. The maximum values of total soluble sugars (83.93 mg/g. s. wt.) and non-reducing sugars (74.79 mg/g. s. wt.) were noticed in NLM 15015. The highest reducing sugars were detected in ILL 8006 (45.68 mg/g. s. wt.) ascorbic acid in LPP 12182 (706 µg/g s. wt.), total phenolic content in NLI 17003 (54,600 µM/g s. wt.), and tannins in NLI 17057 (24,563 µM/g s. wt.). The highest chlorophyll a (236.12 µg/g s. wt.), chlorophyll b (317 µg/g s. wt.), total chlorophyll (552.58 µg/g s. wt.), and lycopene (10.881 µg/g s. wt.) were found in NLH 12097. Maximum total carotenoids were revealed in the local approved variety Markaz 2009 (17.89 µg/g s. wt.). Principal component analysis (PCA), correlation analysis (Pearson's test), and agglomerative hierarchical clustering (AHC) were performed to detect the extent of variation in genotypes. In cluster analysis, all genotypes were categorized into three clusters. Cluster II genotypes showed remarkable divergence with cluster III. According to PCA, the contribution of PC-I regarding tested nutritional parameters toward variability was the highest (39.75%) and indicated positive factor loading for the tested nutritional and biochemical parameters. In conclusion, genotype X 2011S 33-34-32 can be used by the food industry in making pasta, multigrain bread, and snacking foods due to its high protein content for meat alternative seekers. Identified genotypes with high nutritional attributes can be utilized to improve quality parameters in the respective lentil breeding lines.

ABSTRACT

The detection of natural images, such as glaciers and mountains, holds practical applications in transportation automation and outdoor activities. Convolutional neural networks (CNNs) have been widely employed for image recognition and classification tasks. While previous studies have focused on fruits, land sliding, and medical images, there is a need for further research on the detection of natural images, particularly glaciers and mountains. To address the limitations of traditional CNNs, such as vanishing gradients and the need for many layers, the proposed work introduces a novel model called DenseHillNet. The model utilizes a DenseHillNet architecture, a type of CNN with densely connected layers, to accurately classify images as glaciers or mountains. The model contributes to the development of automation technologies in transportation and outdoor activities. The dataset used in this study comprises 3,096 images of each of the "glacier" and "mountain" categories. Rigorous methodology was employed for dataset preparation and model training, ensuring the validity of the results. A comparison with a previous work revealed that the proposed DenseHillNet model, trained on both glacier and mountain images, achieved higher accuracy (86%) compared to a CNN model that only utilized glacier images (72%). Researchers and graduate students are the audience of our article.

ABSTRACT

BACKGROUND: Vasomotor symptoms (VMS), such as hot flashes and night sweats, are highly prevalent and burdensome for women experiencing menopausal transition. Fezolinetant, a selective neurokinin 3 receptor (NK3R) antagonist, is a potential therapeutic option for mitigating VMS. OBJECTIVES: Our aim is to assess the efficacy and evaluate the safety profile of fezolinetant compared with placebo in post-menopausal women suffering from VMS, by pooling all the relevant data and reflecting the most current evidence. SEARCH STRATEGY/SELECTION CRITERIA: An extensive literature search was performed in the PubMed, Medline and Cochrane Library databases from inception until June 2023 to identify relevant trials. DATA COLLECTION AND ANALYSIS: Mean differences (MDs) and 95% confidence intervals (CIs) were calculated for continuous outcomes. Risk ratios (RRs) were calculated for dichotomous outcomes. All statistical analyses were performed using R Statistical Software. MAIN RESULTS: A total of six randomized controlled trials were added. For the frequency of daily VMS, the combined pooled result favored the fezolinetant group over placebo (MD -2.38, 95% CI -2.64 to -2.12; P < 0.001, I2 = 0%). For the severity of daily VMS, fezolinetant was again found to be superior to the placebo group (MD -0.40, 95% CI -0.51 to -0.29; P < 0.001, I2 = 70%). Fezolinetant (120 mg) consistently demonstrated a significant reduction in the severity of daily moderate/severe VMS compared with other doses at both 4 and 12 weeks. Patient-reported outcomes (PROs) of Greene Climacteric Scale (GCS), PROMIS the Sleep Disturbance Short Form 8b and Menopause-Specific Quality of Life (MENQoL) scores indicated significant improvement with fezolinetant. No significant difference in efficacy of fezolinetant at 4 and 12 weeks were observed in any outcome. As for safety, no significant differences in the treatment emergent adverse events at 12 weeks were found between fezolinetant and placebo. CONCLUSIONS: Our study significantly favors fezolinetant over placebo regarding the primary efficacy outcomes of daily moderate to severe VMS frequency and severity, including PROs, while both the groups are comparable in terms of treatment emergent adverse events. Further studies are needed to confirm these findings.

ABSTRACT

Background and aims: Increased use of digital devices in the modern era has led to the development of digital eye strain (DES) or computer vision syndrome in their users. This can result in the development of various ocular and visual symptoms among them. In this study, the authors aimed to view the prevalence of digital eye strain among radiology physicians in Pakistan and their associated risk factors. Materials and methods: A cross-sectional study was conducted to evaluate occupational DES among radiology physicians in Pakistan. The data collection was done using the convenience sampling technique, and the data were analyzed using IBM SPSS for Windows, Version 25.0. Results: Out of the 247 respondents, 33.6% were males and 66.4% were females. 41.7% of them were between 30 and 40 years of age and 51.8% of them were radiology residents. 52.2% of the participants had a refractive error and were using a corrective lens. The majority of the radiologists in our study (84.2%) preferred picture archiving and communication system (PACS) over films and 82.2% of them reported having breaks of less than 15 min. Major symptoms reported by the participants were tired or heavy eyes (69.6%) and headache (69.3%). The proportion of developing DES was higher in females [P=0.001, adjusted odds ratio (aOR)=2.94], radiology residents (P=0.031, aOR=3.29), and working hours of more than 4 h per day (P<0.001, aOR=0.04). Conclusion: With recent advances in the field of radiology in Pakistan, the frequency of developing DES among radiologists is increasing. Being a female, having long working hours, and having noticeable flickers on the digital screens were among the significant factors in developing DES among radiologists.

ABSTRACT

A 90-day study was conducted to investigate the effects of substituting sunflower oil (SFO) for fish oil (FO) on various parameters in Labeo rohita (initial weight 18.21 ± 0.22 g). Five experimental diets with different levels of SFO (up to 7%) substitution for FO (0%, 25%, 50%, 75%, and 100%) were formulated, ensuring equal levels of nitrogen and lipids. The results indicated that even with 100% substitution of SFO with FO, there were no significant differences (P>0.05) were observed in growth performance. The survival rate (SR), hepato-somatic index (HSI), and viscero-somatic index (VSI) as well as whole-body composition were also nonsignificant by SFO substitution. However, the fatty acid profiles in both muscle and liver were influenced (P<0.05) by dietary substitution. Saturated fats (SFA) decreased, while monounsaturated fats (MUFA), and linoleic acid (LA) increased (P<0.05). On the other hand, the contribution of linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) decreased (P<0.05) as the amount of SFO in the diet increased. Hematology parameters, including red blood cells (RBCs), hemoglobin (Hb), and hematocrit (Hct), were not affected. Globulin (GLO) levels decreased significantly (P<0.05), while alanine transaminase (ALT) and aspartate transaminase (AST) activity showed nonsignificant increases (P>0.05). Total protein (TP) increased (P<0.05) at 100% SFO inclusion in the diet, and albumin (ALB) levels increased (P<0.05) at 75% and 100% SFO inclusion in the diet. Cholesterol (CHOL), triacylglycerol (TG), and high-density lipids (HDL) were not significantly affected (P>0.05), while low-density lipids (LDL) were significantly increased (P<0.05) compared to the control group. Cortisol (CORT) and glucose (GLU) levels showed nonsignificant (P>0.05) changes. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) activities in the liver and serum were not significantly (P>0.05) affected, while malondialdehyde (MDA) status was significantly (P<0.05) reduced. In conclusion, the fatty acid profile of the muscle and liver of fish was modified by the diets, and FO can be substituted with SFO up to 100% for L. rohita, which is beneficial for growth and immunity while marinating the lipid contents in fish. Our study revealed that fully replacing fish oil with SFO shows promise in fully replacing FO without compromising the growth and overall health status of the fish.

ABSTRACT

PURPOSE: Demodex blepharitis, often overlooked in ocular surface disease, involves Demodex mites, prevalent ectoparasites on human skin. Current treatments may not effectively eliminate these mites, prompting a need for targeted therapies. Lotilaner, an antiparasitic agent, shows promise. This systematic review and meta-analysis assesses 0.25% lotilaner ophthalmic solution's efficacy in reducing Demodex mite populations and its impact on ocular surface inflammation in Demodex blepharitis patients. METHODS: A comprehensive literature search was performed in the PubMed and Cochrane Library databases from inception until February 2024 to identify relevant trials investigating the use of lotilaner in patients with Demodex blepharitis. The included studies were assessed for quality, and a meta-analysis was conducted to determine the overall treatment effects of lotilaner. Odds ratios (OR) and 95% confidence intervals (CIs) were calculated for binary variables. All statistical analyses were performed using the R Statistical Software. RESULTS: Five studies met the inclusion criteria and were included in this systematic review and meta-analysis. Lotilaner demonstrated significant efficacy in Collarette Cure [OR = 6.64; 95 % CI 3.78 to 11.04; p < 0.00001, I2 = 62 %] %], clinically meaningful collarette reduction [OR = 6.21; 95 % CI 3.67 to 10.49; p < 0.00001, I2 = 90 %], and achieving at least 1-grade collarette improvement [OR = 5.12; 95 % CI (2.96 to 8.88); p < 0.00001, I2 = 90 %] compared to the placebo group. The treatment also resulted in mite eradication [OR = 6.18; 95 % CI 4.67 to 6.18; p < 0.00001, I2 = 34 %], reduction in mite density [OR = 9.37; 95 % CI 5.36 to 16.36; p < 0.00001, I2 = 84 %], and erythema cure [OR = 2.29; 95 % CI 2.24 to 3.39; p < 0.00001, I2 = 5 %] and composite cure [OR = 7.05; 95 % CI 3.66 13. 61; p < 0.00001, I2 = 11 %]. The study suggests that lotilaner is a promising therapeutic option for collarette and associated symptoms, but the high heterogeneity in some outcomes and limited long-term data warrant further research to confirm its effectiveness and safety. CONCLUSION: This systematic review and meta-analysis provides robust evidence supporting the efficacy of 0.25% lotilaner ophthalmic solution in treating Demodex blepharitis. Approval of this targeted therapy represents a significant milestone in ophthalmology and offers a promising treatment option for patients with Demodex blepharitis. Eye care professionals should consider the potential benefits of lotilaner in managing and alleviating the symptoms associated with Demodex infestations on the eyelids. Further research and long-term follow-up studies are warranted to assess the safety and effectiveness of lotilaner in treating Demodex blepharitis.

ABSTRACT

Rheumatic Heart Disease (RHD) remains a leading cause of cardiovascular death (CVD) globally. Mitral Valve repair (MVP) and mitral valve replacement (MVR) are the two most commonly and successfully used techniques to treat the disease. MVP is associated with reduced post-operative complications compared to MVR; however, it carries the risk of valvular fibrosis and scarring. Given the lack of recommendations, inconsistent findings, and paucity of pathophysiological evidence at present, we aimed to conduct a meta-analysis and systematically review the available literature to determine the efficacy and safety of MVP compared to MVR in improving clinical outcomes among patients with RHD. A comprehensive literature search was conducted on MEDLINE (PubMed), Cochrane Central and Scopus from inception till September 2023. The primary objective was early mortality defined as any cause-related death occurring 30 days following surgery. Secondary outcomes included long-term survival defined as the time duration between hospital discharge and all-cause death. Infectious endocarditis, thromboembolic events (including stroke, brain infarction, peripheral embolism, valve thrombosis, and transient ischemic attack), and haemorrhagic events (any serious bleeding event that required hospitalisation, resulted in death, resulted in permanent injury, or required blood transfusion) were all considered as post- operative complications. Additionally aggregated Kaplan-Meier curves were reconstructed for long term survival, freedom from reoperation, and freedom from valve-related adverse events by merging the reconstructed individual patient data (IPD) from each individual study. A significant decrease in early mortality with MV repair strategy versus MV replacement [RR 0.63; P = 0.003) irrespective of mechanical or bioprosthetic valves was noted. The results reported significantly higher long-term survival in patients undergoing MVP versus MVR (HR 0.53; P = 0.0009). Reconstructed Kaplan-Meier curves showed that the long term survival rates at 4, 8, and 12 years were 88.6, 82.0, 74.6 %, in the MVR group and 91.7, 86.8, 81.0 %, in the MVP group, respectively. MVP showed statistically significant reduction in early mortality, adverse vascular events, and better long-term survival outcomes compared to the MVR strategy in this analysis.

ABSTRACT

ß-glucan is a well-documented feed additive for its potent immunostimulatory properties in many farmed fish species. This study examined how it can also be a promising growth promoter, modulate antioxidant enzyme activities, and act as an anti-stress agent in striped catfish (Pangasianodon hypophthalmus). A 12-week feeding experiment was untaken to determine the effects of dietary ß-glucan supplementation at graded levels (0, 0.5, 1.0, and 1.5 g kg-1). Measured indicators suggest that a dietary inclusion level of 1.5 g kg-1 ß-glucan gave the highest positive responses: weight gain (120.10 g fish-1), survival (98.30%), and lower FCR (1.70) (P<0.05). Whole body proximate analysis had only revealed that crude protein was significantly affected by the dietary inclusion of ß-glucan (P<0.05), with the highest protein content (19.70%) being in fish that were fed with 1.5 g kg-1 ß-glucan. Although other inclusion levels (i.e., 0.5 and 1 g kg-1) of ß-glucan did not enhance body protein content (P>0.05). The assessment of fatty acid composition in muscle, liver, and adipose tissues showed modifications with the inclusion of ß-glucan. Antioxidative-related enzyme activities (inc. catalase, glutathione peroxidase, and superoxide dismutase) that were measured in the liver had higher levels when fed with ß-glucan inclusion diets (P<0.05). Following the feed trial, fish were subjected to crowding stress treatment. It was subsequently found that catfish fed with ß-glucan-based diet groups had lower levels of blood stress-related indicators compared to the control group with no dietary ß-glucan. The use of 1.5 g kg-1 of dietary ß-glucan resulted in the lowest measured levels of cortisol (43.13 ng mL-1) and glucose (50.16 mg dL-1). This study has demonstrated that the dietary inclusion of ß-glucan can have functional benefits beyond the immunological enhancements in striped catfish. Furthermore, its use can increase production levels and mitigate the stress associated with intensive farming practices.

ABSTRACT

Glioblastoma multiforme (GBM) IDH-wildtype is the most prevalent brain malignancy in adults. However, molecular mechanisms, which leads to GBM have not been completely elucidated. Granulocyte colony-stimulating factor (GCSF), Granulocyte colony-stimulating factor receptor GCSFR, and Signal transducers and activators of transcription 3 (STAT3) have been involved in the occurrence and development of various cancers, but their role in GBM is little known. Herein, we have investigated the gene and protein expression of GCSF, GCSFR, and STAT3 in 21 tissue biopsy samples and also in tumor associated normal tissue (TANT) samples derived from glioblastoma patients, which revealed significantly differential expression of these genes. To validate our findings, we performed a comprehensive integrated analysis of transcriptomic and proteomic profiling of respective genes by retrieving GBM RNA-sequence data from Genome Atlas Databases. GO and KEGG analysis revealed enrichment in disease-related pathways, such as JAK/STAT pathway activation, which were associated with GBM progression. We further performed computational docking analysis of potential drug candidate Nisin against GCSF, and the results were validated in vitro through cytotoxic activity assay using a human glioblastoma cell line SF-767 in a dose-dependent manner. Our comprehensive analysis reveals that GCSF augments glioma progression, and its blockade with anticancer bacteriocin peptide Nisin can potentially inhibit the growth and metastasis of GBM.

ABSTRACT

Background: In Pakistan, where the burden of communicable diseases remains high, the private sector accounts for 62% of health care provision. Aim: To describe the role of the private sector in communicable disease management in Pakistan and inform a more effective engagement towards achieving Universal Health Coverage. Methods: We searched the literature and available documents on policies, regulations and experiences in private health sector engagement in Pakistan. We interviewed policy level experts regarding the formulation of national health policies and plans and a sample of private providers using a structured questionnaire to assess their awareness of and engagement in communicable disease programmes. Results: Published reports described initiatives to engage the private sector in improving coverage for a package of care and programme-specific initiatives. Pakistan did not have a national policy for structural engagement, and regulations were limited. Policy level experts interviewed perceived the private sector as market-driven and poorly regulated. Thirty-nine percent of private sector providers interviewed were aware or had been trained in procedures or guidelines, and 23% of them had had their performance monitored by government. Conclusion: We recommend that the Ministry of Health provide overall vision for the operations of the public and private health sectors so that both sectors can complement each other towards the achievement of Universal Health Coverage, including for communicable diseases.
