Effects of high-power pain threshold ultrasound technique in patients with knee osteoarthritis: A single-blind randomized controlled trial

Osteoarthritis (OA) is a highly prevalent, degenerative disease of the joints manifested by joint pain, tenderness, decreased function, and limited range of motion (ROM). The current study aimed at evaluating the therapeutic effect of the high-power pain-threshold ultrasound technique (HPPTUS) in comparison with conventional ultrasound (US) techniques in patients with knee osteoarthritis (KOA). A single-masked, pre–post randomized controlled trial was conducted. Fifty participants of both sexes (between 40 and 50 years of age), diagnosed with stage II knee osteoarthritis, participated in this study. They were randomized into two groups: Group A (experimental group, n=25), which received HPPTUS on the knee joint in addition to the traditional treatment (hot packs and isometric exercise for quadriceps), and Group B (control group, n=25), which received conventional ultrasound on knee joint in addition to the traditional treatment (hot packs and isometric exercise for quadriceps). Both groups underwent a four-week treatment plan in which sessions were conducted twice per week. The visual analogue scale (VAS) was used to estimate the intensity of pain, Digital Electronic Pressure Algometer was used to measure pressure pain threshold (PPT) on trigger point around knee, and Digital goniometer was utilized to assess ROM of the knee joint before and after treatment. The MANOVA test revealed statistically significant improvements in all variables (VAS, PPT, knee ROM) post-treatment compared to pre-treatment values in the HPPTUS group (experimental group) (p < 0.05), while the control group revealed statistically significant improvement only in VAS post-treatment compared with pre-treatment (p < 0.05). Comparison between groups revealed statistically significant improvements in VAS, PPT, knee ROM in participants receiving HPPTUS compared with the control group (p < 0.05). High-power ultrasound can be effectively implemented in the treatment of knee OA as it produces significant improvements in the intensity of pain, pressure-pain threshold, and knee joint ROM

Unmasking the Ongoing Challenge of Equid Herpesvirus- 1 (EHV-1) : A Comprehensive Review

Equid herpesviruses (EHVs) are a group of highly impactful viral pathogens that affect horses, presenting a substantial risk to the global equine industry. Among these, equid herpesvirus-1 (EHV-1) primarily causes respiratory infections. However, its ability to spread to distant organs can lead to severe consequences such as abortion and neurological diseases. These viruses can enter a dormant phase, with minimal activity, and later reactivate to trigger active infections at any time. Recently, there has been a notable rise in the prevalence of a particularly devastating strains of EHV-1 known as equid herpesviral myeloencephalopathy (EHM). In the light of dynamic nature of EHV-1, this review provides a thorough overview of EHV-1 and explores how advances in viral biology affect the pathophysiology of viral infection. The information presented here is crucial for understanding the dynamics of EHV-1 infections and creating practical plans to stop the virus's global spread among equid populations

Criminal Violence in Libya: A Descriptive, Autopsy-Based Study of Deaths by Firearms in Tripoli

Abstract The uprisings in some Arab states during the past several years developed into armed conflicts. Therefore, the incidence of violent crimes has become more common with no reliable data on their patterns. The present study aimed to estimate the magnitude of that problem by studying the frequency and pattern of firearm deaths in Tripoli, Libya. A retrospective descriptive study of autopsy cases of firearm deaths was conducted. The data was retrieved from medico-legal reports of cases that were referred to the Forensic Medicine Department of the Judicial Expertise and Research Center, Ministry of justice, Tripoli, Libya during two years from the 1st of January 2014 to the end of December 2015. Structured data sheets were produced. Out of 4,342 unnatural deaths that were autopsied, 774 cases (17.82 %) were due to firearms. Males were commonly targeted. The mean age of victims was 31.7 ± 11 years with significant predominance in the middle age group. Incidence of firearm deaths in non-Libyans increased in 2015 to 8.5%. Homicidal cases represented 92.12% of cases. There was a significant relationship between manner of firing and sex (p ≤ 0.001). In 95.9% of cases, the firing was from a far range. Rifled weapons were used in 98.32% of cases. Head and neck were targeted in 30.8% of cases. There is a high incidence of illegal firearm use and firearm related deaths in Libya. Societal and international efforts are needed to decrease the illicit use and trafficking of such weapons

Decoding the secrets of longevity: unraveling nutraceutical and miRNA-Mediated aging pathways and therapeutic strategies

MicroRNAs (miRNAs) are short RNA molecules that are not involved in coding for proteins. They have a significant function in regulating gene expression after the process of transcription. Their participation in several biological processes has rendered them appealing subjects for investigating age-related disorders. Increasing data indicates that miRNAs can be influenced by dietary variables, such as macronutrients, micronutrients, trace minerals, and nutraceuticals. This review examines the influence of dietary factors and nutraceuticals on the regulation of miRNA in relation to the process of aging. We examine the present comprehension of miRNA disruption in age-related illnesses and emphasize the possibility of dietary manipulation as a means of prevention or treatment. Consolidating animal and human research is essential to validate the significance of dietary miRNA control in living organisms, despite the abundance of information already provided by several studies. This review elucidates the complex interaction among miRNAs, nutrition, and aging, offering valuable insights into promising areas for further research and potential therapies for age-related disorders

Biological characterization of wild-bird-origin avian avulavirus 1 and efficacy of currently applied vaccines against potential infection in commercial poultry

Newcastle disease virus (NDV), the type member of the species Avian avulavirus 1 (formerly known as avian paramyxovirus serotype 1), causes a highly contagious and economically important disease in a myriad of avian species around the globe. While extensive vaccination programs have been implemented in ND-endemic countries, the disease is continuously spreading in commercial, backyard, and wild captive poultry. In order to investigate the evolution of the virus and assess the efficiency of the vaccine regimens that are currently being applied in commercial poultry, four wild-bird-origin NDV strains were characterized biologically, based on mean death time and intracerebral pathogenicity index, and genetically, based on the cleavage motif (112RRQKRF117) in the fusion (F) protein. Based on these features, all of the isolates were characterized as velogenic strains of NDV. Phylogenetic analysis based on the complete genome sequence revealed clustering of these isolates within class II, genotype VII. This class of NDV remains the predominant genotype in the Egyptian poultry industry, as well as in those of many Asian and African countries. To investigate the potential of these wild-bird-origin NDV isolates to cause infection in domesticated poultry and to assess the efficacy of currently available vaccines for protection of commercial poultry, an extensive animal challenge experiment was performed. Cumulative clinicopathological and immunological investigations of virus-challenged chickens indicate that these isolates can potentially be transmitted between chicken and cause systemic infections, and the currently applied vaccines are unable to prevent clinical disease and virus shedding. Taken together, the data represent a comprehensive evaluation of the ability of Egyptian wild-bird-origin NDV strains to cause infection in commercial poultry and highlights the need for a continuous and large-scale surveillance as well as revised vaccine approaches. These integrated and multifaceted strategies would be crucial in any efforts to control and eradicate the disease globally

Comparison of Newly Diagnosed Ocular Hypertension and Open-Angle Glaucoma: Ocular Variables, Risk Factors, and Disease Severity

Purpose. To describe the distribution of ocular variables, risk factors, and disease severity in newly diagnosed ocular hypertension (OH) or open-angle glaucoma (OAG). Methods. Eligible subjects underwent a complete history and examination. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) obtained from multiple logistic regression models were used to compare OAG to OH and advanced to early/moderate OAG. Results. 405 subjects were enrolled: 292 (72.1%) with OAG and 113 (27.9%) with OH. 51.7% had early, 27.1% moderate, and 20.9% advanced OAG. The OR for OAG versus OH was 8.19 (P < 0.0001) for disc notch, 5.36 (P < 0.0001) for abnormal visual field, 1.45 (P = 0.001) for worsening mean deviation, 1.91 (P < 0.0001) for increased cupping, 1.03 for increased age (P = 0.030), and 0.36 (P = 0.010) for smoking. Conclusions. Increased age was a risk for OAG, and smoking decreased the risk of OAG compared to OH. Almost half of the OAG subjects had moderate/advanced disease at diagnosis

Evolutionary Trajectories of Avian Avulaviruses and Vaccines Compatibilities in Poultry.

Newcastle disease virus (NDV) causes one of the highly infectious avian diseases in poultry leading to genuine financial misfortunes around the world. Recently, there has been an increasing trend in the number of ND-associated outbreaks in commercial Jordanian poultry flocks indicating a possible complex evolutionary dynamic of NDV infections in the country. To underpin the dynamics of circulating NDV strains and to assess the vaccine-escape potential, a total of 130 samples were collected from different poultry flocks in six Jordanian Governorates during 2019-2021. Twenty positive isolates, based on real-time reverse transcriptase PCR, were used for further genetic characterization and evolutionary analysis. Our results showed that there is a high evolutionary distance between the newly identified NDV strains (genotype VII.1.1) in this study and the commercially used vaccines (genotypes I and II), suggesting that circulating NDV field strains are under constant evolutionary pressure. These mutations may significantly affect flocks that have received vaccinations as well as flocks with insufficient immunity in terms of viral immunity and disease dynamics. To assess this further, we investigated the efficacy of the heterologous inactivated LaSota or homologous genotype VII.1.1 vaccine for their protection against virulent NDV in chicken. Vaccine-induced immunity was evaluated based on the serology, and protection efficacy was assessed based on clinical signs, survival rates, histopathology, and viral shedding. Chickens vaccinated with the inactivated genotype VII.1.1 based vaccine showed 100% protection with a significant reduction in virus shedding, and ameliorated histopathology lesions compared to LaSota vaccinated chicks that showed 60% protection. These results revealed that the usage of NDV inactivated vaccine from the circulating field strains can successfully ameliorate the clinical outcome and virus pathobiology in vaccinated chicks and will serve as an effective vaccine against the threat posed by commonly circulating NDV strains in the poultry industry

Antiviral Nanomedicine‑Based Approaches against Epstein‑Barr Virus Infection

Purpose of Review The Epstein-Barr virus (EBV) is a common virus around the globe with approximately 98% of adults testing positive against EBV. However, EBV infection typically begins early in the childhood. Owing to the ability to infect various body organ, EBV is linked to a broad spectrum of symptoms, diseases, and inflammatory conditions. Moreover, since EBV exists in both latent and replicating forms in most healthy individuals, any disruption in the balance between the virus and its host can lead to the development of different diseases, including autoimmune disorders and cancer. Given these circumstances, we draw attention to the crucial need for developing prophylactic measures and treatments for EBV and its associated diseases. Recent Findings We propose leveraging the advantages of nanomedicine, such as ferritin and iron oxide nanoparticles, for the creation of EBV vaccines. These advancements can also be applied to developing drugs to treat EBV-associated diseases, such as cancer, autoimmune disorders, and cytokine storm syndrome. Summary We emphasize the urgency of having accessible EBV vaccines, as well as effective treatments for EBV-related diseases, especially when early diagnosis is involved. This approach, which includes comprehensive cytokine profiling for patients, can significantly enhance the effectiveness of treatment programs

Digital pathology for reporting histopathology samples, including cancer screening samples – definitive evidence from a multisite study

Aims To conduct a definitive multicentre comparison of digital pathology (DP) with light microscopy (LM) for reporting histopathology slides including breast and bowel cancer screening samples. Methods A total of 2024 cases (608 breast, 607 GI, 609 skin, 200 renal) were studied, including 207 breast and 250 bowel cancer screening samples. Cases were examined by four pathologists (16 study pathologists across the four speciality groups), using both LM and DP, with the order randomly assigned and 6 weeks between viewings. Reports were compared for clinical management concordance (CMC), meaning identical diagnoses plus differences which do not affect patient management. Percentage CMCs were computed using logistic regression models with crossed random-effects terms for case and pathologist. The obtained percentage CMCs were referenced to 98.3% calculated from previous studies. Results For all cases LM versus DP comparisons showed the CMC rates were 99.95% [95% confidence interval (CI) = 99.90–99.97] and 98.96 (95% CI = 98.42–99.32) for cancer screening samples. In speciality groups CMC for LM versus DP showed: breast 99.40% (99.06–99.62) overall and 96.27% (94.63–97.43) for cancer screening samples; [gastrointestinal (GI) = 99.96% (99.89–99.99)] overall and 99.93% (99.68–99.98) for bowel cancer screening samples; skin 99.99% (99.92–100.0); renal 99.99% (99.57–100.0). Analysis of clinically significant differences revealed discrepancies in areas where interobserver variability is known to be high, in reads performed with both modalities and without apparent trends to either. Conclusions Comparing LM and DP CMC, overall rates exceed the reference 98.3%, providing compelling evidence that pathologists provide equivalent results for both routine and cancer screening samples irrespective of the modality used
