Abstract

Background
To the best of our knowledge, there is a gap in the review of literature about the most suitable varicocelectomy technique in isolating and ligating adherent periarterial vein(s). Consequently, leaving the artery intact or ligating it together with the adherent vein may pose a challenge. We conducted a comparative prospective study to assess the outcomes of the three techniques namely Fisch, sclerotherapy and microvaricoclectomy (MSV).

Results
The patients who underwent MSV showed the longest operative time (66.29 ± 2.78 min), followed by Fisch technique (56.94 ± 3.07 min) then sclerotherapy (55.45 ± 1.99). Thus, the difference in the operative time between the three techniques was statistically significant (P < 0.001). Regarding the postoperative right vein diameter, MSV group showed the largest diameter (2.14 ± 0.15 mm), followed by Fisch technique (2.13 ± 0.15 mm) then sclerotherapy (1.75 ± 0.42 mm). Regarding the postoperative left vein diameter, MSV group showed again the largest diameter (2.17 ± 0.21 mm), followed by Fisch technique (2.14 ± 0.15 mm) then sclerotherapy (1.75 ± 0.42 mm). Moreover, the patients who underwent sclerotherapy showed the highest postoperative progressive sperm motility percent (25.27 ± 4.00%), followed by Fisch technique (21.56 ± 7.30%) then MSV group (19.85 ± 6.33%). Post hoc pair wise comparisons revealed that sclerotherapy and Fisch technique had a significantly higher effectiveness in reducing operative time than MSV. Additionally, it revealed that sclerotherapy technique had a significantly higher effectiveness in reducing postoperative vein diameters measurement than MSV and Fisch technique. Post hoc pair wise comparisons revealed that sclerotherapy technique had a significantly higher effectiveness in improving the postoperative progressive sperm motility percent than MSV.
Patients who underwent the 3 techniques demonstrated statistically significant differences between baseline and post-operative vein diameter, reflux duration, sperm concentration, progressive sperm motility, progressive motile count/ejaculate and sperm abnormal forms.

Conclusion
The 3 techniques showed significant improvement in the semen parameters after 3 months in the studied patients. However, sclerotherapy technique showed a significantly higher effectiveness in improving the postoperative progressive sperm motility percent compared to MSV.

Abstract
Maize is the third most important grain crop worldwide after wheat and rice; it is a vital global crop, serving as a key source of food, animal feed, and industrial products, making it essential for food security and economic stability in many countries. Drought stress adversely affects water uptake and can stunt growth, reducing the overall productivity of maize. So, this study was carried out to investigate the cytogenetic effects of gamma radiation and drought stress on maize SC131 genotype, focusing on chromosomal aberrations in seedling root meristems induced by varying doses of gamma irradiation (50, 100, 150, 200, and 250 Gray) and drought stress imposed by 10% polyethylene glycol (PEG). The present study also aims to evaluate the impact of these treatments on growth parameters under a controlled pot experiment. Additionally, molecular polymorphism induced by both gamma irradiation and drought stress was analyzed using Real-Time quantitative PCR techniques for DREB2, ERF, and EF transcription factors. Also, under a field condition experiment, maize plants were subjected to the same gamma irradiation doses and drought stress by reducing the number of irrigations, with subsequent evaluations of yield attributes to assess the overall impact of treatments on plant performance. The study also investigates the sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE) banding patterns of proteins in grains yielded under the influence of gamma radiation and drought treatments. Findings of the current investigation indicate that the low dose of gamma radiation (50 Gray) not only induces cytogenetic changes but also enhances drought tolerance and improves yield characteristics, suggesting that targeted gamma irradiation could serve as a viable strategy to bolster maize resilience in challenging environmental conditions.

Abstract

Background
Particulate matter less than 2.5 microns in aerodynamic diameter (PM2.5) is a significant air pollutant known to adversely affect respiratory health and increase the incidence of chronic obstructive pulmonary disease (COPD). Furthermore, climate change exacerbates these impacts, as extreme temperatures and relative humidity (RH) levels can intensify the effects of PM2.5. This study aims to examine the joint effects of PM2.5, temperature, and RH on the risk of COPD.

Methods
A case–control study was conducted among 1,828 participants from 2017 to 2022 (995 COPD patients and 833 controls). The radial basis function interpolation was utilized to estimate participants' individual mean and differences in PM2.5, temperature, and RH in 1-day, 7-day, and 1-month periods. Logistic regression models examined the associations of environmental exposures with the risk of COPD adjusting for confounders. Joint effects of PM2.5 by quartiles of temperature and RH were also examined.

Results
We observed that a 1 µg/m3 increase in PM2.5 7-day and 1-month mean was associated with a 1.05-fold and 1.06-fold increase in OR of COPD (p < 0.05). For temperature and RH, we observed U-shaped effects on OR for COPD with optimal temperatures identified as 21.2 °C, 23.8 °C, and 23.8 °C for 1-day, 7-day, and 1-month mean temperature, respectively, and optimal RH levels identified as 73.8%, 76.7%, and 75.4% for 1-day, 7-day, and 1-month mean RH, respectively (p < 0.05). The joint effect models show that high temperatures (> 23.5 °C) and both extremely low (69.3%) and high (80.9%) RH levels generally exacerbate the effects of PM2.5 on OR for COPD, especially over longer exposure durations.

Conclusion
The joint effects of PM2.5, temperature, and RH on the risk of COPD underscore the importance of air pollution control and comprehensive research to mitigate COPD risk in the context of climate change.
Differences in fatty infiltration in thigh muscles and physical function between people with and without knee osteoarthritis and similar body mass index: a cross-sectional study
Authors: Aily Jessica B. , de Noronha Marcos , Ferrari Ricardo J. , Mattiello Stela M. 
Published: February 2025

Abstract

Background
People with knee osteoarthritis (OA) may have more thigh intermuscular and intramuscular adipose tissue (interMAT and intraMAT, respectively) compared to those without knee OA. Literature has not considered differences in body mass index (BMI) in the context of comparing intraMAT and interMAT between individuals with and without knee OA, matched for BMI (± 1 kg/m²). This study aims to compare interMAT and intraMAT, along with physical function (including knee extension strength), between individuals with and without knee osteoarthritis, matched by BMI.

Methods
Participants aged ≥ 40 years with symptomatic and radiological knee OA group (grade 2 and 3 on the Kellgren and Lawrence (KL) scale) were included in the affected group, while those with no knee pain and no radiological knee OA changes were included in the unaffected group. No participants were lost to assessment, ensuring complete data analysis for all participants. We used independent t-test and mean difference (95% CI) to compare thigh intraMAT and interMAT volume, self-reported measures (WOMAC questionnaire), physical function measures, and knee extension strength between groups.

Results
Forty-six participants were analyzed (23 in each group). The affected group had significantly higher intraMAT compared to the unaffected group (p < 0.05), but no differences were observed for interMAT. Self-reported outcomes and physical function measures were worse in the affected group, as was knee extension strength.

Conclusion
People with knee OA present higher levels of intraMAT and poorer physical function compared to those without knee OA. These findings highlight the need for further research to explore the clinical significance of intraMAT and its potential impact on physical function in this population.

Abstract

Background
Endodontic treatment aims to eliminate pulp tissue, microorganisms, and toxins while creating an environment conducive to tissue revitalization and regeneration. Sodium hypochlorite, the gold-standard irrigant, is effective but has significant cytotoxic effects, prompting the need for safer alternatives. This study investigates the cytotoxicity, cell proliferation, adhesion to dentin, and osteogenic differentiation of cells exposed to Dual Rinse HEDP, curcumin, and sodium hypochlorite (2.5%) for 1, 5, and 15 min, focusing on their potential application in revitalization and regenerative endodontic protocols.

Methodology
Samples were assigned to groups based on the irrigant used: control, HEDP, curcumin, or sodium hypochlorite (2.5%) for exposure durations of 1, 5, and 15 min. Cytotoxicity was assessed using the MTT assay, with optical density measured at the specified times. Cell proliferation was evaluated via the Trypan blue exclusion test, with viable cells counted using a hemocytometer. Data were presented as mean and standard deviation (SD) values and statistical significance was set at p < 0.05 for all tests. Cell adherence to dentin discs was analyzed using scanning electron microscopy (SEM) after 5-min irrigant exposure. Osteogenic differentiation was assessed through alizarin red staining for calcium deposition and quantitative PCR analysis of BMP-2, TGF-β1, VEGF, and DSPP gene expression.

Results
Cell cytotoxicity differed significantly across groups (p < 0.05), with HEDP showing the best results at 1 and 5 min. After 15 min, Group II had the highest value, followed by Group I. HEDP also recorded the highest cell proliferation, followed by curcumin. HEDP exhibited substantial calcium deposition and significantly upregulated BMP-2, TGF-β1, VEGF, and DSPP gene expression, surpassing other materials. Curcumin moderately promoted calcified nodule formation. Osteogenic media also induced significant gene upregulation.

Conclusions
Dual Rinse HEDP and curcumin are tissue-friendly. Dual rinse HEDP efficiently increases stem cell adherence to dentin discs and their osteogenic differentiation.
So, this irrigant has the potential to be used in regeneration protocols.
Informational support for women with endometriosis: a scoping review
Authors: Senyel Deniz , Boyd James H. , Graham Melissa 
Published: February 2025

Abstract

Background
Ten per cent of women of reproductive age suffer from endometriosis, a painful and incurable disease that leaves women with severe implications for their health and overall well-being. Due to the absence of a cure and the limited effectiveness of available treatments, acquiring accurate information is paramount for women to successfully navigate both their daily lives and the complexities of the healthcare system. This scoping review aimed to map the current literature on women with endometriosis information needs, their information seeking behaviour, and the format and scope of current information resources available.

Methods
The scoping review was conducted using the JBI methodology for scoping reviews and reported according to the PRISMA-ScR statement. The final search was conducted in August 2024, through the databases Medline, Cinahl, Embase, Scopus, and WebofScience. Studies on information resources on endometriosis and information seeking behaviour as well as information needs of women with endometriosis were eligible for inclusion.

Results
The majority of the 25 included studies focused on information resources, specifically webpages and social media sites. While few studies analysed information seeking behaviour and information needs, the evidence shows women’s high interest in a broad spectrum of information topics. Across all studies, the internet was the most important access point for information.

Conclusion
Addressing the absence of systematic analyses on the information seeking behaviour and needs of women with endometriosis is crucial for future research. This step is essential for the development of customised information resources that cater specifically to the diverse needs of women affected by endometriosis.

Abstract

Background
Over the last decades, universal health coverage (UHC) has been promoted in south-east Asia (SEA), where many countries still need to ensure adequate financial protection to their populations. However, successful health financing reforms involve complex interactions among a range of stakeholders, as well as with context factors, including shocks and crises of different nature. In this article, we examine recent health financing reforms in Nepal, Thailand and Indonesia, using a political economy lens. The objective is to understand whether and how crises can be utilised to progress UHC and to analyse the strategies used by reformers to benefit from potential windows of opportunity.

Methods
The study adopted a retrospective, comparative case study design, using a shared framework and tools. The case studies mapped the contexts, including economic, political, social trends and any shocks which had recently occurred. A focal health financing reform was chosen in each setting to examine, probing the role of crisis in relation to it, through the key elements of the reform process, content and actors. Data sources were largely qualitative and included literature and document review (144 documents included across the three cases) and key informant interviews (26 in total).

Results
The findings, which bring out similarities and differences in the roles played by change teams across the settings, highlight the importance of working closely with political leaders and using a wide range of strategies to build coalitions and engage or block opponents. Changing decision rules to block veto points was significant in one case, and all three cases used participation and dialogue strategically to further reforms. More broadly, the links with context emerged as important, with prior conflicts and economic crises creating a sense of urgency about addressing health inequities, while in all countries appeal was made to underlying values to enhance the legitimacy of the reforms.

Conclusion
The lessons from these case studies include that technical teams can and should engage in Political Economy Analysis (PEA) thinking and strategizing, including being aware of and adaptable to the changing PEA landscape and prepared to take advantage of windows of opportunity, including, but not limited to, those emerging from crisis. There is a need for more empirical studies in this area and sharing of lessons to support future reforms to increase health coverage and financial protection, including in the face of likely shocks.

Abstract

Background
Epilepsy is a neurological disorder characterized by recurrent seizures, tightly associated with neuroinflammation. Activation of inflammatory cells and molecules in damaged nervous tissues plays a pivotal role in epilepsy. Caffeic acid, one of the most abundant polyphenols in coffee, has shown potent protective effects as a phytomedicine in various neurological disorders. However, the direct protein targets and exact molecular mechanisms of caffeic acid in epilepsy, remain largely elusive.

Purpose
This study aimed to explore the protective effects of caffeic acid in epilepsy and elucidate its underlying mechanism.

Methods
In this study, we established pentylenetetrazol-induced acute and kindling models of seizures. Additionally, a BV2 microglial cellular inflammation model was established by lipopolysaccharide stimulation. The potential direct protein targets of caffeic acid in BV2 cells were analyzed using an activity-based protein profiling (ABPP) with a caffeic acid probe. Various methods such as pull-down assay, immunofluorescence and cellular heat transfer assays were used for experimental validation. The anti-inflammatory effects of caffeic acid in LPS-activated BV2 cells was proved by knocking down the target protein.

Results
Here, we found that caffeic acid exhibits antiepileptic effects in pentylenetetrazol-induced epilepsy mice and exerts anti-neuroinflammation effect in vivo and in vitro. Besides, we discovered that caffeic acid directly binds to aconitate decarboxylase 1 and influenced its enzymatic activity. Moreover, we indicated that caffeic acid exhibits anti-neuroinflammation effect through aconitate decarboxylase 1 mediated PERK-NF-κB pathway in vitro.

Conclusion
In summary, this study elucidates, for the first time, the potential antiepileptic targets and mechanism of action of caffeic acid using the ABPP strategy. Our study provides evidence supporting the utilization of caffeic acid as a promising therapeutic agent for treating epilepsy and neuroinflammation-related disorders.
Optimal needle characteristics for classical inferior alveolar nerve block anesthesia: a systematic review
Authors: Abd-Elsabour Mennat Allah Ashraf , Gamal-AbdelNaser Ayat 
Published: February 2025

Abstract

Objectives
Although frequently applied, inferior alveolar nerve block (IANB) is associated with high rate of complications, beside its unpredictable success; partly due to improper needle choice. Evidence of the ideal needle contradicts in literature. Therefore, this review aims to assess the effect of needle characteristics on the outcomes of IANB.

Materials and methods
A systematic search was performed on MedLine via Pubmed, Cochrane Library, LILACS, Science Open, EBSCOhost, Scopus, Egyptian Knowledge Bank (EKB), and Google scholar; beside searching grey literature and hand searching. The review included randomized controlled trials comparing needles of difference in any of the characteristics (gauge, length, bevel, alloy) used for IANB regarding their effects on pain, success of anesthesia and aspiration. The authors ran the search, selected the eligible studies, assessed the risk of bias using RoB 1 and extracted the data of the finally included studies. All the steps were performed in duplicates.

Results
The search yielded a total of 2,812 records. After de-duplication and excluding ineligible studies by title and abstract then by full text, the review included nine eligible studies. The compared needle interventions included: gauges (23G, 24G, 25G, 26G, 27G and 30G), lengths (12 mm, 25 mm, 32 mm, 35 mm, 42 mm), and internal diameters (0.265 mm, 0.215 mm, 0.3 mm and 0.4 mm). All studies had high risk of bias, adopted different assessment methods for the outcomes, and included participants with differences in baseline characteristics.

Conclusions
The level of the available evidence introduced by primary studies hinder concluding the optimal needle characteristics; keeping the research question unanswered. However, within the limitations of the heterogenous studies, available data favors thinner needles for less pain during needle insertion; otherwise, data of the other outcomes was inconclusive.

Clinical relevance
Thinner needles are favored for less pain during insertion; but standardized future studies are essentially needed for solid conclusions. A detailed standard protocol is, therefore, proposed.

Published: February 2025

Abstract

Background
The prevalence of dengue fever (DF), a mosquito-borne viral disease, is rising worldwide. Its severe manifestations like thrombocytopenia and plasma leakage are associated with increased mortality. Ultrasound-detected gallbladder wall thickening (GBWT) has been suggested as a potential indicator of the severity of the disease.

Aims
This systematic review and meta-analysis evaluated the predictive value of GBWT in identifying patients at risk for severe dengue.

Methods
Following the PRISMA 2020 guidelines, we conducted a systematic search of Web of Science, PubMed, Embase, and Scopus. Among the inclusion criteria were original studies that assessed GBWT across various dengue severity categories. Then, we performed a meta-analysis using a random effects model and subgroup analyses based on severity criteria to determine the relationship between GBWT and severe dengue.

Results
For the meta-analysis, 19 studies qualified for the inclusion criteria. There was a significant association between GBWT and severe dengue, according to the odds ratio (OR) of 2.35 (95% CI 1.88–2.82, p < 0.001). The subgroup analysis revealed consistent results for thrombocytopenia (OR: 2.65) and plasma leakage (OR: 2.26), among other severity criteria.

Conclusions
A reliable ultrasound indicator, GBWT can help identify patients at risk for severe dengue early on, improving clinical decision-making and patient outcomes. However, the possibility of differential diagnosis requires cautious interpretation.
