RESUMO

Aim: In our study, we evaluated the gender dimorphism among dental measurements of selected people in a South Indian district. Methodology: In our research, 500 participants between 17 and 25 years of age were included after taking their maxillary arch impressions. Utilizing Korkhaus compass and digital caliper, depth of palatal area as well as maxillary arch as a whole was done. T-test was done to initiate the comparative analysis between the palatal arch and complete maxillary arch depths where P < 0.05 was denoted significant statistically. Results: It was recorded that complete maxillary arch depth measurements were increased in case of men as compared to women, whereas the measurements related to depth of the palatal arch were not statistically significant. Conclusion: In our research, we found that complete maxillary arch depth can be utilized for gender segregation accompanied with other auxiliary methods. The mean value for both these measurements can be utilized as a standard measurement for advance research.

RESUMO

Transient monocular visual loss (TMVL), also known as transient monocular blindness or amaurosis fugax ("fleeting blindness"), is a temporary loss of vision often due to ischemia to the retina. While acute TMVL should be considered an emergency that further requires exhaustive investigation, there are some cases in which TMVL arises secondary to benign causes. Age has a major impact in the diagnosis of ischemia and although the differential diagnosis of TMVL can be broad, timely and appropriate history, examination, diagnostic testing, and treatment can be vision- or life-saving. We review the causes of TMVL and the impact of age on the differential diagnoses and management.

RESUMO

BACKGROUND: Vascular Ehlers-Danlos syndrome (vEDS) is a rare connective tissue disorder with a high risk for arterial, bowel, and uterine rupture, caused by heterozygous pathogenic variants in COL3A1. The aim of this cohort study is to provide further insights into the natural history of vEDS and describe genotype-phenotype correlations in a Dutch multicenter cohort to optimize patient care and increase awareness of the disease. METHODS: Individuals with vEDS throughout the Netherlands were included. The phenotype was charted by retrospective analysis of molecular and clinical data, combined with a one-time physical examination. RESULTS: A total of 142 individuals (50% female) participated the study, including 46 index patients (32%). The overall median age at genetic diagnosis was 41.0 years. More than half of the index patients (54.3%) and relatives (53.1%) had a physical appearance highly suggestive of vEDS. In these individuals, major events were not more frequent (P=0.90), but occurred at a younger age (P=0.01). A major event occurred more often and at a younger age in men compared with women (P<0.001 and P=0.004, respectively). Aortic aneurysms (P=0.003) and pneumothoraces (P=0.029) were more frequent in men. Aortic dissection was more frequent in individuals with a COL3A1 variant in the first quarter of the collagen helical domain (P=0.03). CONCLUSIONS: Male sex, type and location of the COL3A1 variant, and physical appearance highly suggestive of vEDS are risk factors for the occurrence and/or early age of onset of major events. This national multicenter cohort study of Dutch individuals with vEDS provides a valuable basis for improving guidelines for the diagnosing, follow-up, and treatment of individuals with vEDS.

RESUMO

Neuro-ophthalmologic diseases include a broad range of disorders affecting the afferent and efferent visual pathways. Recently, monoclonal antibody (mAb) therapies have emerged as a promising targeted approach in the management of several of these complex conditions. Here, we describe the mechanism-specific applications and advancements in neuro-ophthalmologic mAb therapies. The application of mAbs in neuro-ophthalmologic diseases highlights our increasing understanding of disease-specific mechanisms in autoimmune conditions such as neuromyelitis optica, thyroid eye disease, and myasthenia gravis. Due to the specificity of mAb therapies, applications in neuro-ophthalmologic diseases have yielded exceptional clinical outcomes, including both reduced rate of relapse and progression to disability, visual function preservation, and quality of life improvement. These advancements have not only expanded the range of treatable neuro-ophthalmologic diseases but also reduced adverse events and increased the response rate to treatment. Further research into neuro-ophthalmologic disease mechanisms will provide accurate and specific targeting of important disease mediators through applications of future mAbs. As our understanding of these diseases and the relevant therapeutic targets evolve, we will continue to build on our understanding of how mAbs interfere with disease pathogenesis, and how these changes improve clinical outcomes and quality of life for patients.

RESUMO

BACKGROUND: To determine whether a neuro-ophthalmic curriculum would improve National Football League (NFL) game officials' self-rated knowledge and interest in neuro-ophthalmic principles to improve precision and accuracy of NFL play-calling. METHODS: The formalized and structured neuro-ophthalmic principles (NOP) curriculum was introduced to 121 NFL game officials, 17 replay officials, and 4 officiating staff who attended the NFL Official Training Camp in Irving, Texas, on September 8 and 9, 2023. Before and after the lecture and videos were introduced, participants completed an optional hard-copy feedback form pertaining to self-reported NOP knowledge, likelihood of using said terms, and interest in future content of NOP applicable NFL officiating. Paired 2-tailed t tests were used for statistical analysis to directly compare the self-reported knowledge before and after the neuro-ophthalmic curriculum introduction. RESULTS: One hundred forty-two participants completed the prelecture and postlecture feedback forms self-reported knowledge after the NOP curriculum was given to the NFL officiating staff. All (142/142) participants completed a survey. There was a statistically significant improvement in the mean ratings of the prelecture vs. postlecture understanding of the specific neuro-ophthalmic terms pertinent to NFL game officials (2.6 [95% CI, 2.3-3.0] vs. 7.9 [95% CI, 7.6-8.2], P < 0.001) and 2.7 [95% CI, 2.3-3.0] vs. 7.7 [95% CI, 7.4-8.0]), respectively. There was a statistically significant greater likelihood of using said terms prelecture vs. postlecture (2.9 [95% CI, 2.4-3.4] vs. 7.5 [95% CI, 7.2-7.9], P < 0.001). CONCLUSIONS: This study found a statistically significant improvement in neuro-ophthalmic knowledge and a greater likelihood of using NOP terms following the NOP curriculum. NFL game officials, replay officials, and staff are interested in expanding their knowledge in the vision science of neuro-ophthalmic concepts and applications involved in play-calling. We hope that our pilot data will lead to a model of education that will improve the precision and accuracy of NFL play-calls by officials on game days.

RESUMO

AIM: To evaluate the long-term clinical effectiveness of computed tomography (CT)-guided transforaminal cervical epidural steroid injection using an anterolateral approach for the treatment of cervical radiculopathy (CR) using well-established robust clinical scoring systems for neck pain and neck disability. Despite its widespread use, evidence to support the long-term benefit of routine cervical epidural steroid injection is currently very limited. MATERIALS AND METHODS: This study included 113 patients with magnetic resonance imaging (MRI)-confirmed CR who underwent a steroid injection at a single cervical level via a unilateral transforaminal anterolateral approach. Pain was assessed quantitatively at pre-injection, 15 minutes post-injection, 1 month, 3 months, and at 1 year. Neck disability was assessed using the Oswestry Neck Disability Index (NDI) at pre-injection, 1 month, 3 months, and 1 year time points. RESULTS: Eighty patients completed the study. Sixty per cent reported reduced neck pain (mean pain reduction, 55%), which was clinically significant in 45% cases. Furthermore, 66% reported an improvement in neck disability (mean improvement, 51%), which was clinically significant for 56% patients. Clinically significant good outcomes in both neck pain and neck disability were evident from as early as 1-month, and importantly, were independent both of pre-treatment CR characteristics (including severity of pre-injection neck pain or disability) and of findings on pre-injection MRI imaging. CONCLUSION: Transforaminal anterolateral approach CT-guided epidural steroid injection resulted in a clinically significant long-term improvement in both neck pain and disability for half of the present cohort of patients with unilateral single-level CR. This improvement was independent of the severity of the initial symptoms and pre-injection MRI findings.

RESUMO

BACKGROUND: The rising prevalence of electronic cigarette (E-cigarette) use among adolescents is a major public health concern. This study investigates the prevalence of E-cigarette use among male adolescents in Al-Ahsa, Saudi Arabia, and explores associated factors. METHODOLOGY: A cross-sectional study was conducted from December 2022 to April 2023, involving 476 male students aged 12 to 19. Data were collected through structured questionnaires, covering sociodemographic information, E-cigarette usage patterns, reasons for use, sources of acquisition, awareness of nicotine content, and perceptions of harm. Statistical analysis was performed using SPSS 25 (IBM Corp., Armonk, NY), with significance set at p < 0.05. RESULTS: The study revealed a prevalence of 17.4% E-cigarette use among participants, with 12.6% using E-cigarettes exclusively and 4.8% concurrently with traditional tobacco cigarettes. Key findings included initiation as early as age eight, sustained and frequent use, and motivations including peer influence (61.4%), curiosity (31.3%), and flavored options (26.5%). Online platforms (34.9%) and shopping malls (28.9%) were the primary sources of E-cigarette acquisition. Most participants were aware of the nicotine content (84.3%) and believed E-cigarettes were harmful (86.7%). Importantly, 69.9% expressed intentions to quit, with 44.6% planning to do so within 30 days. Significant associations were found between E-cigarette use, education level, and having friends who smoke. CONCLUSION: This study highlights the prevalence of E-cigarette use among male adolescents in Al-Ahsa, Saudi Arabia, and identifies peer influence, curiosity, and appealing flavors as driving factors. Targeted prevention and intervention programs, along with regulatory efforts to restrict access, are urgently needed to address this growing public health issue. Increasing awareness of E-cigarette risks and providing cessation support are vital steps towards mitigating E-cigarette use among Saudi male adolescents.

RESUMO

Regenerative endodontics represents a paradigm shift in dental therapy, with the potential to not only restore damaged dental tissues but also to preserve the vitality of teeth. At the heart of this innovative approach is cell homing, a technique that harnesses the body's own healing mechanisms by recruiting endogenous stem cells to the site of dental injury for effective tissue regeneration. This review delves into the intricate processes of cell homing in the context of regenerative endodontics, particularly focusing on its application in immature teeth with open apices. It examines the role of bioactive molecules, scaffolds, and growth factors in orchestrating cell migration and differentiation within the root canal space. In addition, the review addresses the current limitations in clinical practice, such as the challenges in completely regenerating the pulp-dentin complex and the unpredictability in long-term outcomes. It also explores future possibilities, including the potential for more refined and effective regenerative strategies. By providing a comprehensive overview of the current state of cell homing in regenerative endodontics, this article aims to contribute to the ongoing development of advanced therapeutic techniques that could revolutionize endodontic treatment and improve patient care.

RESUMO

Therapy-Induced Senescence (TIS) is a form of senescence that is typically described in malignant cells in response to the exposure of cancer chemotherapy or radiation but can also be precipitated in non-malignant cells. TIS has been shown to contribute to the development of several cancer therapy-related adverse effects; however, evidence on its role in mediating chemotherapy-induced neurotoxicity, such as Chemotherapy-induced Peripheral Neuropathy (CIPN), is limited. We here show that cisplatin treatment over two cycles (cumulative dose of 23 mg/kg) provoked mechanical allodynia and thermal hyperalgesia in Sprague-Dawley rats. Isolation of dorsal root ganglia (DRG) from the cisplatin-treated rats demonstrated robust SA-ß-gal upregulation at both day 8 (after the first cycle) and day 18 (after the second cycle), decreased lmnb1 expression, increased expression of cdkn1a and cdkn2a, and of several factors of the Senescence-associated Secretory Phenotype (SASP) (Il6, Il1b, and mmp9). Moreover, single-cell calcium imaging of cultured DRGs revealed a significant increase in terms of the magnitude of KCl-evoked calcium responses in cisplatin-treated rats compared to vehicle-treated rats. No significant change was observed in terms of the magnitude of capsaicin-evoked calcium responses in cisplatin-treated rats compared to vehicle-treated rats but with decreased area under the curve of the responses in cisplatin-treated rats. Further evidence to support the contribution of TIS to therapy adverse effects is required but should encourage the use of senescence-modulating agents (senotherapeutics) as novel palliative approaches to mitigate chemotherapy-induced neurotoxicity.

RESUMO

Respiratory complex I (NADH:ubiquinone oxidoreductase) is essential for cellular energy production and NAD+ homeostasis. Complex I mutations cause neuromuscular, mitochondrial diseases, such as Leigh Syndrome, but their molecular-level consequences remain poorly understood. Here, we use a popular complex I-linked mitochondrial disease model, the ndufs4-/- mouse, to define the structural, biochemical, and functional consequences of the absence of subunit NDUFS4. Cryo-EM analyses of the complex I from ndufs4-/- mouse hearts revealed a loose association of the NADH-dehydrogenase module, and discrete classes containing either assembly factor NDUFAF2 or subunit NDUFS6. Subunit NDUFA12, which replaces its paralogue NDUFAF2 in mature complex I, is absent from all classes, compounding the deletion of NDUFS4 and preventing maturation of an NDUFS4-free enzyme. We propose that NDUFAF2 recruits the NADH-dehydrogenase module during assembly of the complex. Taken together, the findings provide new molecular-level understanding of the ndufs4-/- mouse model and complex I-linked mitochondrial disease.

RESUMO

PURPOSE OF REVIEW: This review will examine the most current evidence for Metabolic and Bariatric Surgery (MBS) in the pediatric population, specifically in terms of weight loss outcomes and improvement in comorbid conditions and complications. Additionally, we compare surgical and non-surgical interventions, review current guidelines, and propose a stepwise evidence-based approach to the management of obesity in children. RECENT FINDINGS: MBS is a safe option for appropriately selected pediatric patients which leads to significant and sustained weight loss. This weight loss is associated with improvement of related comorbid conditions. Laparoscopic sleeve gastrectomy (LSG) has emerged as the procedure of choice with a better safety profile. Despite the evidence, very few adolescents undergo MBS. New pharmacologic agents specifically the GLP-1/GIP agents have shown early promise especially in patients under body mass index 40, but the long-term effects are unknown. MBS is an effective tool in the management of pediatric obesity, and its use has been recommended by professional societies. Early referral to a multidisciplinary obesity team can help identify appropriate patients.

RESUMO

PURPOSE: Genome sequencing (GS) enables comprehensive molecular analysis of tumors and identification of hereditary cancer predisposition. According to guidelines, directly determining pathogenic germline variants (PGVs) requires pretest genetic counseling, which is cost-ineffective. Referral for genetic counseling based on tumor variants alone could miss relevant PGVs and/or result in unnecessary referrals. METHODS: We validated GS for detection of germline variants and simulated 3 strategies using paired tumor-normal GS data of 937 metastatic patients. In strategy-1, genetic counseling before tumor testing allowed direct PGV analysis. In strategy-2 and -3, germline testing and referral for post-test genetic counseling is based on tumor variants using Dutch (strategy-2) or Europen Society for Medical Oncology (ESMO) Precision Medicine Working Group (strategy-3) guidelines. RESULTS: In strategy-1, PGVs would be detected in 50 patients (number-needed-to counsel; NTC = 18.7). In strategy-2, 86 patients would have been referred for genetic counseling and 43 would have PGVs (NTC = 2). In strategy-3, 94 patients would have been referred for genetic counseling and 32 would have PGVs (NTC = 2.9). Hence, 43 and 62 patients, respectively, were unnecessarily referred based on a somatic variant. CONCLUSION: Both post-tumor test counseling strategies (2 and 3) had significantly lower NTC, and strategy-2 had the highest PGV yield. Combining pre-tumor test mainstreaming and post-tumor test counseling may maximize the clinically relevant PGV yield and minimize unnecessary referrals.

RESUMO

Abstract Transplanting time and genotype contribute to improving crop yield and quality of eggplant (Solanum melongena L.). A field experiment was conducted to investigate the impact of foliar applied of triacontanol (TRIA) and eggplant genotypes 25919, Nirala, 28389 and Pak-10927,transplanted on 1 March,15 March, and 1 April on exposure to high air temperature conditions. The experiment was performed according to Randomized Complete Block Design and the data was analyzed by using Tuckey,s test . The TRIA was applied at 10µM at flowering stage; distilled water was used as the control. Rate of photosynthesis and transpiration, stomatal conductance, water use efficiency, and effects on antioxidative enzymes (superoxide dismutase, catalase and peroxidase) were evaluated. The 10µM TRIA increased photosynthesis rate and water use efficiency and yield was improved in all genotypes transplanted at the different dates. Foliar application of 10µM TRIA increased antioxidative enzyme activities (SOD, POD & CAT) and improved physiological as well as biochemical attributes of eggplant genotypes exposed to high heat conditions. Highest activity of dismutase enzyme 5.41mg/1g FW was recorded in Nirala genotype in second transplantation. Whereas, lowest was noted in PAK-10927 (2.30mg/g FW). Maximum fruit yield was found in accession 25919 (1.725kg per plant) at 1st transplantation with Triacontanol, whereas accession PAK-10927 gave the lowest yield (0.285 kg per plant) at control treatment on 3rd transplantation. Genotype, transplanting date and application of TRIA improved growth, yield and quality attributes under of heat stress in eggplant.


Resumo O tempo de transplante e o genótipo contribuem para melhorar a produtividade e a qualidade da cultura da berinjela (Solanum melongena L.). Um experimento de campo foi conduzido para investigar o impacto da aplicação foliar de triacontanol (TRIA) e genótipos de berinjela 25919, Nirala, 28389 e Pak-10927, transplantados em 1 de março, 15 de março e 1 de abril de exposição a condições de alta temperatura do ar. O experimento foi realizado de acordo com o Randomized Complete Block Design e os dados foram analisados pelo teste de Tuckey. O TRIA foi aplicado a 10 µM na fase de floração; água destilada foi utilizada como controle. Taxa de fotossíntese e transpiração, condutância estomática, eficiência do uso da água e efeitos sobre as enzimas antioxidantes (superóxido dismutase, catalase e peroxidase) foram avaliados. O TRIA 10 µM aumentou a taxa de fotossíntese e a eficiência do uso da água e o rendimento foi melhorado em todos os genótipos transplantados nas diferentes datas. A aplicação foliar de TRIA 10µM aumentou as atividades das enzimas antioxidantes (SOD, POD e CAT) e melhorou os atributos fisiológicos e bioquímicos de genótipos de berinjela expostos a condições de alto calor. A atividade mais elevada da enzima dismutase 5,41mg / 1g FW foi registrada no genótipo Nirala no segundo transplante. Considerando que o mais baixo foi observado em PAK-10927 (2,30 mg / g FW). A produtividade máxima de frutos foi encontrada no acesso 25919 (1,725 ​​kg por planta) no 1º transplante com Triacontanol, enquanto o acesso PAK-10927 deu a menor produção (0,285 kg por planta) no tratamento de controle no 3º transplante. Genótipo, data de transplante e aplicação de TRIA, melhoramento do crescimento, rendimento e atributos de qualidade sob estresse térmico em berinjela.
