Numerous studies have established a link between gene variants within the inflammasome complex and the incidence of periodontitis and cardiovascular illness across various ethnic groups. This study investigated the association between PYCARD gene polymorphism and susceptibility to periodontal disease and coronary heart disease (CHD) and their correlation with clinical periodontal indices. A total of 120 participants were enrolled, categorized into four groups: 30 healthy controls (C), 30 patients with generalized periodontitis (P), 30 patients with atherosclerotic CHD but clinically healthy periodontium (AS-C), and 30 patients with both atherosclerotic CHD and generalized periodontitis (AS-P). We recorded demographic data, collected blood samples, and measured periodontal indices, including plaque index, clinical attachment loss, bleeding on probing, and pocket depth. The genomic variant of the PYCARD gene was analyzed using a conventional polymerase reaction. A significant prevalence of T and G allele mutations and a higher distribution of CT and TT genotypes in PYCARD C/T (rs8056505) and the AG genotype in PYCARD A/G (rs372507365) were observed in groups P, AS-P, and AS-C. These single nucleotide polymorphisms (SNPs) were also positively correlated with the severity of clinical periodontitis indices. Our findings suggest that the increased frequency of T and G alleles and the distribution of CT, TT, and AG genotypes in PYCARD SNPs are significantly associated with an elevated risk for periodontal disease and CHD. These SNPs may participate in the pathogenesis of these conditions. The study reinforces the potential role of these genetic markers as risk factors for both diseases in the Iraqi population.

UNASSIGNED: Several vaccines have been approved against COVID-19, and 5 have been used in Indonesia. Due to the decrease in antibody levels 3 to 6 months after the second dose of CoronaVac, healthcare workers received the third booster of mRNA vaccine (mRNA-1273) to increase the antibody level. This study aimed to evaluate the risk factors of anti-S-RBD IgG levels differences in healthcare workers.
UNASSIGNED: This study is a retrospective cohort study of 576 healthcare workers without previous SARS-CoV-2 infection who received 2 doses of CoronaVac and the third dose of mRNA-1273 6 months after the second dose. Blood samples were obtained 2nd, 6th, 12th, and 24th weeks after the second dose of CoronaVac vaccine administration, with mRNA-1273 booster on week 20. Quantitative measurements of IgG antibodies were performed with Elecsys Anti-SARS-CoV-2 S immunoassay. We identify the baseline factors predicting post-vaccination antibody titers using univariate and multivariate linear regression analysis.
UNASSIGNED: This study comprised 576 participants aged 32 years old, 72.05% female, and 45.84% from high-risk occupation subgroups. The median antibodies titer level on the 2nd, 6th, 12th, and 24th weeks after the second vaccine dose administration were 40.99 u/mL, 42.01 u/mL, 54.78 u/mL, and 23,225 u/mL. Antibody levels trended highest in female and younger age group (20-29 years old).
UNASSIGNED: The third dose of vaccine increased the quantitative SARS-CoV-2 spike IgG antibody titers and eliminated differences in antibodies titer by gender.

UNASSIGNED: Chest Computerized Tomography has been widely used in COVID patients\' assessment. Hence the question arises as to whether there is any correlation between the Ct value and findings on Chest CT scan or clinical presentation of the patient. We wanted to test the hypothesis of whether low Ct values (≤30) in RT-PCR were associated with a high mortality rate, CT scan findings, or with comorbidities such as immunosuppression and lung disease.
UNASSIGNED: The radiographic records and RT-PCR Ct values of 371 COVID patents diagnosed at the American University of Beirut Medical Center were reviewed.
UNASSIGNED: We found out that the sensitivity of chest CT scan compared to RT-PCR, the gold standard, turned out to be 74% (95% CI 69-79%). Specificity, on the other hand was 33% (95% CI 16-55%). The positive predictive value of CT was 94% (95% CI 91-97%) and the negative predictive value was 8% (95% CI 4-16%). low Ct values in RT-PCR were not associated with a higher mortality rate (p-value = 0.416). There was no significant positive association between low Ct value and suspicious CT scan findings (typical and indeterminate for COVID-19), with a p-value of 0.078. There was also no significant association between low Ct value and immunosuppression (p-value = 0.511), or lung disease (p-value =0.06). CT scan findings whether suspicious or not for COVID-19 infection, were not shown to be significantly associated with respiratory symptoms of any kind.No association was found between a history of lung disease, immunosuppression and suspicious CT scan findings for COVID-19.
UNASSIGNED: As long as this pandemic exists, nucleic acid testing was and remains the gold standard of COVID-19 diagnosis worldwide and in our community as it has a superior diagnostic accuracy to CT scan and higher sensitivity (94% vs 74%).

In 2005 and 2010, the European Commission (EC) published two subsequent \'Road Maps\' to provide options for relaxation of the bans on the application of animal proteins in feed. Since then, the food production system has changed considerably and demands for more sustainability and circularity are growing louder. Many relaxations envisioned in the second Road Map have by now been implemented, such as the use of processed animal proteins (PAPs) from poultry in pig feed and vice versa. However, some legislative changes, in particular concerning insects, had not been foreseen. In this article, we present a new vision on legislation for increased and improved use of animal by-products. Six current legislative principles are discussed for the bans on animal by-products as feed ingredients: feed bans; categorization of farmed animals; prohibition unless explicitly approved; approved processing techniques, the categorization of animal by-products, and monitoring methods. We provide a proposal for new guiding principles and future directions, and several concrete options for further relaxations. We argue that biological nature of farmed animals in terms of dietary preferences should be better recognised, that legal zero-tolerance limits should be expanded if safe, and that legislation should be revised and simplified.

UNASSIGNED: Periodontitis is an inflammation of the periodontal apparatus leads to destruction of connective tissue attachment and tooth loss. Red complex bacteria may contribute to disease initiation. Bacterial infection in periodontitis leads to a low-grade chronic infection and inflammation in distant organs. Notably, aging can affect the immune response.
UNASSIGNED: The aim of this study was to analyze the effect of aging on oral hygiene and inflammation condition. Moreover, to evaluate the correlation between the oral hygiene condition and red complex bacterial load in subgingival plaque.
UNASSIGNED: In this cross-sectional study, we examined 20 adult and 20 elderly subjects with periodontitis. Clinical parameters included Oral Hygiene Index Simplified (OHI-S) and Papillary Bleeding Index (PBI) were recorded. Subgingival plaque was collected from the tooth with a probing depth of 5-7 mm and analyzed with a reverse transcription polymerase chain reaction (RT-PCR) for red complex bacteria quantification. Statistical analysis was performed, respectively.
UNASSIGNED: Both groups had poor oral hygiene conditions, reflected by high OHI-S and PBI. The quantity of red complex bacteria (P. gingivalis, T. denticola, T. forsythia) in the elderly group was significantly higher in comparison to the adult group. There was significant strong linear relationship between OHI-S and red complex bacteria (r < 1, p < 0.05). Only P. gingivalis bacteria with PBI values had a strong linear relationship and statistically significant. (r < 1, p < 0.05). P. gingivalis load was significantly higher than T. denticola and T. forsythia load, and it correlated with poor oral hygiene in the adult and elderly groups and with PBI in the elderly group.
UNASSIGNED: Aging affects to the red complex bacterial load and oral hygiene condition, but not the inflammation. These findings contribute to the development of novel treatment strategies focusing on bacterial aspect for periodontitis in the elderly.

Alveolar echinococcosis in slaughtered horses remains a public health issue. This study aimed to develop a Recombinase polymerase amplification (RPA) assay targeting the mitochondrial NADH dehydrogenase subunit 5 (Nad5) gene of Echinococcus multilocularis for the rapid detection of equine alveolar echinococcosis. Thirty-six hepatic solid nodules obtained from each horse (n = 36) were evaluated based on histopathological examination and Nad5-targeted PCR and then submitted to the RPA assay. The results of the developed RPA assay were 94.4% consistent with those of Nad5 PCR and Cohen\'s kappa coefficient value was 0.89 statistically, indicating high agreement. In addition, the RPA assay using the plasmid samples was one hundredfold more sensitive than PCR testing. Consequently, these results suggest that the performance of the RPA assay developed in this study is equal to that of conventional PCR testing.

UNASSIGNED: Tuberculosis (TB) continues to be a common disease in developing countries, among which middle ear TB is rare. Furthermore, it is relatively difficult to make an early diagnosis and provide follow-up treatment for middle ear TB. So, it is necessary to report this case for reference and further discussion.
UNASSIGNED: We reported 1 case of multidrug-resistant tuberculosis otitis media. TB otitis media is rare in tuberculosis; multidrug-resistant TB otitis media is even more rare. Our paper analyzes the possible causes, imaging, molecular biology, pathology, and clinical manifestations of multidrug-resistant TB otitis media.
UNASSIGNED: PCR and DNA molecular biology techniques are highly recommended for the early diagnosis of multidrug-resistant TB otitis media. Early, effective anti-tuberculosis treatment is the guarantee for further recovery for patients with multidrug-resistant TB otitis media.

Phenotypic switching of vascular smooth muscle cells is a central process in abdominal aortic aneurysm (AAA) pathology. We found that knockdown TCF7L1 (transcription factor 7-like 1), a member of the TCF/LEF (T cell factor/lymphoid enhancer factor) family of transcription factors, inhibits vascular smooth muscle cell differentiation. This study hints at potential interventions to maintain a normal, differentiated smooth muscle cell state, thereby eliminating the pathogenesis of AAA. In addition, our study provides insights into the potential use of TCF7L1 as a biomarker for AAA.

Water-soluble protein (WSP) from fish meat is abundant in the waste effluent generated via the surimi manufacturing process. This study investigated the anti-inflammatory effects and mechanisms of fish WSP using primary macrophages (MΦ) and animal ingestion. MΦ were treated with digested-WSP (d-WSP, 500 µg/mL) with or without lipopolysaccharide (LPS) stimulation. For the ingestion study, male ICR mice (5 weeks old) were fed 4% WSP for 14 days following LPS administration (4 mg/kg body weight). d-WSP decreased the expression of Tlr4, an LPS receptor. Additionally, d-WSP significantly suppressed the secretion of inflammatory cytokines, phagocytic ability, and Myd88 and Il1b expressions of LPS-stimulated macrophages. Furthermore, the ingestion of 4% WSP attenuated not only LPS-induced IL-1β secretion in the blood but also Myd88 and Il1b expressions in the liver. Thus, fish WSP decreases the expressions of the genes involved in the TLR4-MyD88 pathway in MΦ and the liver, thereby suppressing inflammation.

UNASSIGNED: Asymptomatic Plasmodium carriers form the majority of malaria-infected individuals in most endemic areas. A proportion of these asymptomatically infected individuals carry gametocytes, the transmissible stages of malaria parasites, that sustain human to mosquito transmission. Few studies examine gametocytaemia in asymptomatic school children who may form an important reservoir for transmission. We assessed the prevalence of gametocytaemia before antimalarial treatment and monitored clearance of gametocytes after treatment in asymptomatic malaria children.
UNASSIGNED: A total of 274 primary school children were screened for P. falciparum parasitaemia by microscopy. One hundred and fifty-five (155) parasite positive children were treated under direct observation with dihydroartemisinin-piperaquine (DP). Gametocyte carriage was determined by microscopy seven days prior to treatment, day 0 before treatment, and on days 7, 14 and 21 post initiation of treatment.
UNASSIGNED: The prevalence of microscopically-detectable gametocytes at screening (day -7) and enrolment (day 0) were 9% (25/274) and 13.6% (21/155) respectively. Following DP treatment, gametocyte carriage dropped to 4% (6/135), 3% (5/135) and 6% (10/151) on days 7, 14 and 21 respectively. Asexual parasites persisted in a minority of treated children, resulting in microscopically detectable parasites on days 7 (9%, 12/135), 14 (4%, 5/135) and 21 (7%, 10/151). Gametocyte carriage was inversely correlated with the age of the participants (p = 0.05) and asexual parasite density (p = 0.08). In a variate analysis, persistent gametocytaemia 7 or more days after treatment was significantly associated with post-treatment asexual parasitaemia at day 7 (P = 0.027) and presence of gametocytes on the day of treatment (P < 0.001).
UNASSIGNED: Though DP provides both excellent cure rates for clinical malaria and a long prophylactic half-life, our findings suggest that after treatment of asymptomatic infections, both asexual parasites and gametocytes may persist in a minority of individuals during the first 3 weeks after treatment. This indicates DP may be unsuitable for use in mass drug administration strategies towards malaria elimination in Africa.
