Surgical interventions for intractable migraine: a systematic review and meta-analysis.

BACKGROUND: Migraine affects approximately 14-15% of the global population, contributing to nearly 5% of the world's health burden. When drug treatments prove ineffective for intractable migraines, highly specific surgical interventions emerge as potential solutions. We aimed to analyze surgical approaches for these refractory or intractable migraines through a systematic review and meta-analysis. METHODS: We conducted a literature search across databases such as PubMed, Scopus, Web of Science, and Embase, focusing on studies related to migraines and surgical outcomes. We considered clinical trials or observational studies that included any surgical intervention for refractory or intractable migraines, emphasizing key outcomes such as reductions in migraine intensity, Migraine Disability Assessment scores (MIDAS), and 50% Migraine Headache Index (MHI) reduction rates. Statistical analyses were performed using R version 4.3. RESULTS: Eleven studies were included in the systematic review. A meta-analysis of four studies involving overall 95 patients showed a significant reduction in mean migraine intensity scores using ONS (-2.27, 95% CI: -3.92 to -0.63, P=0.021). Three studies with 85 patients showed an average MIDAS score reduction of -52.3, though this was not statistically significant (95% CI: -136.85 to 32.19, P=0.116). Two additional studies corroborated these reductions in MIDAS scores. Nerve decompression surgery showed a substantial decrease in the average migraine intensity (from 8.31 down to 4.06). Median MIDAS score dropped from 57 to 20. Two studies indicated a success rate of 40% and 82%, respectively, in achieving a 50% reduction in the Migraine MHI through nerve decompression. Findings from two studies suggest that septorhinoplasty and sinus surgery effectively decrease migraine intensity scores. CONCLUSION: The existing evidence emphasizes the potential advantages of surgical interventions as a promising approach to managing intractable or refractory migraines. However, robust and comprehensive research is crucial to refine and solidify the efficacy of these surgical methods, aiming for widespread benefits for patients, considering cost-effectiveness factors.

Risk of Corneal Transplant Rejection Following COVID-19 Vaccination: A Systematic Review and Meta-analysis.

INTRODUCTION: The COVID-19 pandemic has initiated an unparalleled global vaccination campaign, raising concerns about the vaccine's effects on various health conditions, including the risk of corneal transplant rejection. This systematic review aimed to identify the relationship between COVID-19 vaccination and rejection of corneal transplant, filling a significant gap in the existing medical literature. METHODS: A literature search was performed across multiple databases up to February 12, 2024, to identify studies evaluating the risk of corneal transplant rejection post-COVID-19 vaccination. Eligible studies were original research that reported outcomes of corneal graft rejection following vaccination. Nested Knowledge web software facilitated screening and data extraction. The Newcastle-Ottawa Scale was employed for quality assessment. A meta-analysis was conducted to calculate the aggregated relative risk (RR) utilizing R software version 4.3. RESULTS: Six studies were included in the qualitative synthesis, with four meeting the criteria for meta-analysis. These studies varied in geographic location, surgical techniques, and types of vaccines used. The pooled RR for corneal transplant rejection following COVID-19 vaccination was 0.816 (95% CI 0.178-1.453), indicating no significant risk of rejection. No statistical heterogeneity was observed among the studies (I2 = 0%). CONCLUSIONS: This review and meta-analysis found no significant evidence that COVID-19 vaccination increases the risk of corneal graft rejection. However, the current evidence is insufficient to conclusively determine the vaccine's safety for corneal transplant recipients. These findings underscore the need for additional research to confirm these preliminary results and investigate the long-term effects of COVID-19 vaccination on corneal transplants, aiming to provide evidence-based guidance to healthcare providers and patients.

Caregivers' Experience with Lip Taping as a Presurgical Orthopedic Treatment for Cleft Lip and Palate Defects.

BACKGROUND: This study aimed to assess caregivers' experiences and perceptions of applying lip taping as presurgical orthopedic therapy (PSO) for infants with a cleft lip and palate. METHODS: A retrospective survey was conducted, inviting parents to respond to a series of structured questions between September 2022 and June 2023. The questionnaire focused on evaluating parents' experience with lip taping, a crucial component of PSO. Descriptive statistics and the Chi-square test were employed to analyze relationships between categorical variables. RESULTS: Of the 157 participants, overall, 122 completed the survey, forming the dataset for analysis. A majority (90.0%) reported sufficient experience in using lip taping and no major difficulties with lip taping application. Caregivers with higher education levels exhibited a significantly positive correlation (p = 0.015). Additionally, 93.4% confirmed the efficacy of lip taping for premaxillary segment retraction, with this outcome being correlated with caregivers' knowledge and education (p = 0.008). Interestingly, caregivers' age also demonstrated a substantial association (p = 0.020). CONCLUSIONS: While a vast majority expressed positive experiences with lip taping as a presurgical treatment, continuous, tailored education on cleft lip and palate is imperative. This education should be directed towards caregivers and individuals offering direct support to parents of children with CLP, ensuring optimal care and preparation for surgical treatment.

Efficacy and safety of stem cell therapy in patients with dilated cardiomyopathy: An umbrella review of systematic reviews.

BACKGROUND: Stem cell therapy (SCT) has emerged as a potential therapeutic avenue, with various cell types being explored for their efficacy in treating DCM. However, the safety and efficacy of these therapies have been the subject of numerous systematic reviews. This umbrella review aims to consolidate the existing evidence on stem cell interventions for DCM, providing a comprehensive overview of the current research landscape. METHODS: This review was conducted following the JBI and PRISMA guidelines. Systematic reviews and meta-analyses of randomized controlled trials (RCTs) evaluating the safety and efficacy of SCT for DCM were included. Outcomes such as 6MWT, LVEDD, LVEF, MACE, NYHA, and QoL, among others, were considered. A literature search was executed across databases like PubMed, Embase, Web of Science, and Cochrane Database up to October 07, 2023. The quality of the included reviews was assessed using the JBI Checklist for Systematic Reviews and Research Syntheses. Data synthesis was carried out in both narrative and tabular formats, with the GRADE criteria guiding the determination of evidence certainty. RESULTS: Nine systematic reviews met the inclusion criteria. LVEF found to be significantly improved with SCT. LVEDD and LVEDV assessments yielded mixed results, with some reviews observing significant changes. LVESV showed consistent reductions across multiple studies. BNP concentrations post-interventions were explored in several studies, with mixed findings. Health-related quality of life (HRQL) showed varied results, with some studies noting improvements and others finding no significant differences. NYHA classifications and 6-MWT results indicated potential benefits from stem cell treatments. SCT was observed to be generally safe. The certainty of evidence was low or very low for most of outcomes. CONCLUSION: SCT showed has shown promise in treating DCM, with many studies highlighting its safety and potential benefits. Nonetheless, the existing data has its limitations due to biases in the RCTs studies. To truly establish the benefits of SCT for DCM, future high quality RCTS, are crucial.

The accuracy and retention of presurgical infant orthopaedics constructed from different polymer materials: A comparative study.

Objectives: This laboratory-based study aimed to evaluate and compare the accuracy and retention of moulding plates when used as pre-surgical orthopaedic appliances (PSIOs) for infants with cleft lip and/or palate (CL/P). Methods: Ten moulding plates were fabricated from three different materials (total sample size: 30), including polymethyl methacrylate (PMMA), a hard clear aligner (PET-G polymer), and a dual-layered hard and soft clear aligner (mixed PET-G/EVA) on ten three-dimensional (3D) printed working models. Accuracy was evaluated by measuring the virtual gap between the data acquired from the moulding plate and the working model after the optical scanning at each of the designated 36 points for each plate. Exocad software was used to facilitate all virtual alignments and measurements. Retention was measured using a digital gauge that quantified the traction force required to separate the plates from the retention test cast (a soft resin printed cast). Results: PET-G plates exhibited the best fit with the working cast, with overall adaptations of 0.146 ± 0.012 for PET-G, 0.250 ± 0.073 for PET-G/EVA, and 0.294 ± 0.113 for PMMA. For region-specific misfit, PET-G plates exhibited superior accuracy across all regions, with mean discrepancies of 0.16 ± 0.08 mm, 0.15 ± 0.061 mm, and 0.12 ± 0.128 mm in the anterior, middle, and posterior regions, respectively. Retention for PET-G was significantly higher than the other materials, with a mean of 3.34 N ± 0.487, as opposed to 1.65 N ± 0.331for PMMA and 1.27 N ± 0.239 for PET-G/EVA (P < 0.05). Conclusions: Moulding plates constructed from PET-G exhibited a better fit and higher retention than those made from PET-G/EVA and PMMA. Clinical significance: Collectively, our findings suggest that the selection of PET-G for PSIO appliances could have clinical significance by potentially improving treatment outcomes in infants with CL/P.

Enhanced antimicrobial efficacy of chlorhexidine-encapsulated halloysite nanotubes incorporated in presurgical orthopedic appliances: an in vitro, controlled study.

AIMS AND OBJECTIVE: Presurgical infant's orthopedic appliances (PSIOs) play an increasingly crucial role in the interdisciplinary management of neonatal CLP, aiming to improve and maintain adequate nasolabial aesthetics, followed by primary lip/nasal surgery in both unilateral and bilateral CLP cases. The use of PSIOs in cleft lip and palate patients can lead to contamination with oral microflora, acting as a potential reservoir for infectious microorganisms. Acrylic surfaces might provide retention niches for microorganisms to adhere, and inhabit, which is difficult to control in immunocompromised patients, thus predisposing them to increased infection risks. The objective of this multi-assay in vitro study was to investigate the effects of incorporating chlorhexidine-loaded halloysite nanotubes (CHX-HNTs) fillers on the morphological, cytotoxic, release, and antimicrobial characteristics of self-cured acrylic polymethyl methacrylate (PMMA) material used in pre-surgical orthopedic appliances. METHODS: Disk-shaped PMMA specimens were prepared with varying proportions of CHX-HNTs. A control group without any addition served as a reference, and four experimental samples contained a range of different concentrations of CHX-HNTs (1.0, 1.5, 3, and 4.5 wt%). The antimicrobial efficacy was assessed using an agar diffusion test against common reference microorganisms: Candida albicans, Staphylococcus aureus, Streptococcus pneumoniae, and Streptococcus agalactiae. Cytotoxicity was examined using the L929 cell line (mouse fibroblasts) through a (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide, MTT) cell viability assay. The release kinetics of CHX were monitored using UV-spectral measurements. The statistical analysis used a one-way ANOVA followed by Tukey's post hoc test. RESULTS: The integration of CHX-HNTs in PMMA exhibited a substantial dose-dependent antifungal and antibacterial effect against microorganisms at tested mass fractions (1.0 to 4.5 wt%). CHX release was sustained for up to 60 days, supporting prolonged antimicrobial activity. Furthermore, no significant cytotoxicity was determined in the L929 fibroblast cell line (control), indicating the biocompatibility of the CHX-HNTs-enhanced PMMA. CONCLUSION: Incorporating CHX-HNTs in PMMA successfully enhanced its antimicrobial properties, providing sustained CHX release and superior antimicrobial efficacy. These findings demonstrate the potential of antimicrobial nanoparticles in dental therapies to improve therapeutic outcomes. However, rigorous further clinical trials and observational studies are warranted to validate the practical application, safety, and efficacy. CLINICAL RELEVANCE: This study has the potential to make a major impact on the health of infants born with cleft lip and palate by helping to reduce the prevalence of infectious illnesses. The incorporation of CHX-HNTs into PMMA-based appliances is a novel promising preventive approach to reduce microbial infections.

The Potential Therapeutic Effects of Platelet-Derived Biomaterials on Osteoporosis: A Comprehensive Review of Current Evidence.

Osteoporosis is a chronic multifactorial condition that affects the skeletal system, leading to the deterioration of bone microstructure and an increased risk of bone fracture. Platelet-derived biomaterials (PDBs), so-called platelet concentrates, such as platelet-rich plasma (PRP) and platelet-rich fibrin (PRF), have shown potential for improving bone healing by addressing microstructural impairment. While the administration of platelet concentrates has yielded positive results in bone regeneration, the optimal method for its administration in the clinical setting is still debatable. This comprehensive review aims to explore the systemic and local use of PRP/PRF for treating various bone defects and acute fractures in patients with osteoporosis. Furthermore, combining PRP/PRF with stem cells or osteoinductive and osteoconductive biomaterials has shown promise in restoring bone microstructural properties, treating bony defects, and improving implant osseointegration in osteoporotic animal models. Here, reviewing the results of in vitro and in vivo studies, this comprehensive evaluation provides a detailed mechanism for how platelet concentrates may support the healing process of osteoporotic bone fractures.

New Propargyloxy Derivatives of Galangin, Kaempferol and Fisetin-Synthesis, Spectroscopic Analysis and In Vitro Anticancer Activity on Head and Neck Cancer Cells.

Head and neck cancer (HNC) therapy is limited; therefore, new solutions are increasingly being sought among flavonoids, which exhibit numerous biological properties, including potential anticancer activity. However, because they are mostly insoluble in water, are unstable and have low bioavailability, they are subjected to chemical modification to obtain new derivatives with better properties. This study aimed to synthesize and analyze new propargyloxy derivatives of galangin, kaempferol and fisetin, and to evaluate their anticancer activity against selected HNC cell lines. The obtained derivatives were assessed by spectroscopic analysis; next, their anticancer activity was evaluated using a flow cytometer and real-time cell analysis. The results showed that only the fisetin derivative was suitable for further analysis, due to the lack of crystal formation of the compound. The fisetin derivative statistically significantly increases the number of cells in the G2/M phase (p < 0.05) and increases cyclin B1 levels. A statistically significant increase in the number of apoptotic cells after being exposed to the tested compound was also observed (p < 0.05). The data indicate that the obtained fisetin derivative exhibits anticancer activity by affecting the cell cycle and increasing apoptosis in selected HNC lines, which suggests its potential use as a new medicinal agent in the future.

Burden of stillbirths among women vaccinated with COVID-19 vaccines: A systematic review and meta-analysis.

OBJECTIVE: To estimate the global burden of stillbirths among pregnant women with the COVID-19 vaccination. DATA SOURCE: In this systematic review and meta-analysis, a literature search was carried out in PubMed, Cochrane and Scopus until February 4, 2023, with language restriction (English). STUDY SELECTION: Title-abstract screening followed by full text review was done independently by two authors, based on the research question, "What is the prevalence of stillbirths among the pregnant women vaccinated with COVID-19 vaccines?" DATA EXTRACTION: Two authors independently extracted the relevant data from every study. The third author resolved the conflicts. This study was registered in PROSPERO and followed the PRISMA guidelines. DATA ANALYSIS: A Random effects model was applied to assess the pooled estimate of stillbirths. The I2 test was used to assess the heterogeneity of the articles included in the study. For checking the publication bias, the Doi plot and the contour-enhanced funnel plot were utilized. RESULTS: The database systematic search yielded 168 articles; 11 of them were determined to be eligible for systematic review and 8 of them ended up being included for meta-analysis. The pooled prevalence of stillbirth in pregnant women vaccinated against COVID-19 infection was 0.00509 (5 per 1000 live births delivered by pregnant women vaccinated against COVID-19 (95% CI: 0.00003-0.01676). Statistically significant heterogeneity was reported across studies (I2 = 98%; p < 0.01). CONCLUSIONS: The study concluded that vaccination against COVID-19 among pregnant women had a low stillbirth rate. It adds to the existing evidence that the COVID-19 vaccine is safe and can be taken during pregnancy.

Oral Lesions as the Primary Manifestations of Behçet's Disease: The Importance of Interdisciplinary Diagnostics-A Case Report.

BACKGROUND: Behçet's disease (BD) is a rare chronic auto-inflammatory systemic disease with non-specific oral manifestations, categorised as generalised variable vessel vasculitis that requires an interdisciplinary approach to diagnose due to its phenotypic heterogeneity. Whilst the oral lesions that reoccur in BD underpin the complex diagnostic process, the crucial role of dental professionals is highlighted in a case report summarised herein. We present a case of a 47-year-old male referred to the Oral Medicine Department by a rheumatologist after previous hospitalization for thrombosis of the iliac vein and inferior vena cava. He had elevated inflammatory C-reactive protein biomarker and an increased erythrocyte sedimentation rate. Recurrent episodes of folliculitis, oral and genital ulcers were reported. Clinical examination revealed multiple ulcerations in the oral mucosa. The complementary, histopathological analysis performed to rule out other disorders, based on excisional biopsy, showed non-keratinised stratified squamous epithelium with areas of exocytosis and ulceration. The connective tissue presented an intense mixed inflammatory infiltrate, congested blood vessels, haemorrhage, vasculitis, and HLA-B genotyping identified the expression of HLA-B15, further supporting the BD diagnosis. Treatment was initiated with colchicine, prednisolone, and weekly subcutaneous administration of methotrexate and resulted in the complete remission of oral lesions and no recurrence of other manifestations. CONCLUSIONS: This BD case report emphasizes the importance of a multidisciplinary approach in diagnosing BD, including the use of histopathological assessment and genetic profiling. It highlights the significance of thorough intraoral assessment and referral to a multidisciplinary team for diagnosis. The oral manifestations of BD as the primary symptoms often indicate underlying major systemic pathologies. The authors stress the need for a structured diagnostic algorithm to facilitate timely and effective management of BD.

Kaempferol and Fisetin-Related Signaling Pathways Induce Apoptosis in Head and Neck Cancer Cells.

Despite the relative effectiveness of standard cancer treatment strategies, head and neck cancer (HNC) is still considered one of the leading causes of mortality and morbidity. While selected bioactive compounds of plant origin reveal a pro-apoptotic effect, kaempferol and fisetin flavonols have been reported as potential anti-cancer agents against malignant neoplasms. To date, their exact role in signaling pathways of head and neck cancer cells is largely unknown. Based on the various methods of cytotoxicity testing, we elucidated that kaempferol and fisetin inhibit proliferation, reduce the capacity of cell migration, and induce apoptosis in SCC-9, SCC-25, and A-253 HNC cells in a dose-dependent manner in vitro (p < 0.05, fisetin IC50 values of 38.85 µM, 62.34 µM, and 49.21 µM, and 45.03 µM, 49.90 µM, and 47.49 µM for kaempferol-SCC-9, SCC-25, and A-253, respectively). The obtained results showed that exposure to kaempferol and fisetin reduces Bcl-2 protein expression, simultaneously leading to the arrest in the G2/M and S phases of the cell cycle. Kaempferol and fisetin inhibit cell proliferation by interfering with the cell cycle, which is strongly associated with the induction of G2/M arrest, and induce apoptosis by activating caspase-3 and releasing cytochrome c in human HNC cells. In addition, investigating flavonols, by inhibiting anti-apoptotic proteins from the Bcl-2 family and damaging the mitochondrial transmembrane potential, increased the level of cytochrome c. While flavonols selectively induce apoptosis of head and neck cancer cells, they may support oncological therapy as promising agents. The discovery of new derivatives may be a breakthrough in the search for effective chemotherapeutic agents with less toxicity and thus fewer side effects.

Oral side effects of COVID-19 vaccines in 32 European countries: Analysis of EudraVigilance reports.

The recent reports of oral side effects (SEs) following COVID-19 vaccination warrant further investigation into their prevalence, severity, and aetiology. This study was conducted to synthesize the first-ever population-level evidence about oral SEs of COVID-19 vaccines in Europe. The European Union Drug Regulating Authorities Pharmacovigilance (EudraVigilance) database was accessed in August 2022 to extract summary data of all potential oral SEs reported after COVID-19 vaccination. The data were reported descriptively and cross-tabulated to facilitate sub-group analysis per vaccine type, sex, and age group. Dysgeusia was the most commonly reported oral SE (0.381 case per each 100 received reports), followed by oral paraesthesia (0.315%), ageusia (0.296%), lip swelling (0.243%), dry mouth (0.215%), oral hypoaesthesia (0.210%), swollen tongue (0.207%), and taste disorder (0.173%). Females had significantly (Sig. < 0.001) a higher prevalence of all most common (top 20) oral SEs, except for salivary hypersecretion, which was equally prevalent among females and males. The present study revealed a low prevalence of oral SEs, with taste-related, other sensory and anaphylactic SEs being the most common SEs in Europe, similar to what was found earlier among the US population. Future studies should explore the potential risk factors of oral sensory and anaphylactic SEs to verify whether they are causally linked to COVID-19 vaccines.

Ophthalmic Manifestations of the Monkeypox Virus: A Systematic Review and Meta-Analysis.

BACKGROUND: The accurate estimation of the prevalence of mpox-induced ophthalmic lesions will enable health departments to allocate resources more effectively during the ongoing mpox pandemic. The aim of this meta-analysis was to estimate the global prevalence of ophthalmic manifestations in mpox patients. METHODS: A systematic search was carried out in seven databases-Pub Med, Scopus, Web of Science, EMBASE, ProQuest, EBSCOHost, and Cochrane-for studies published on or before 12 December 2022. The pooled prevalence of ophthalmic manifestations was estimated by the random effects model. Risk of bias assessment of the studies and sub-group analysis to explain heterogeneity were undertaken. RESULTS: Overall, 12 studies were included, with 3239 confirmed mpox cases, among which 755 patients reported ophthalmic manifestations. The pooled prevalence of ophthalmic manifestations was 9% (95% confidence interval (CI), 3-24). Studies from Europe reported a very low prevalence of ocular manifestations of 0.98% (95% CI 0.14-2.31), compared to studies from Africa with a substantially higher prevalence of 27.22% (95% CI 13.69-43.26). CONCLUSIONS: A wide variation in the prevalence of ocular manifestations among mpox patients was observed globally. Healthcare workers involved in mpox-endemic African countries should be aware of ocular manifestations for early detection and management.

Tissue Engineering Supporting Regenerative Strategies to Enhance Clinical Orthodontics and Dentofacial Orthopaedics: A Scoping, Perspective Review.

The personalized regenerative therapeutic strategies applicable in the structural and functional repair of maxillofacial/dental defects are expected to extend beyond the limits of what is currently possible in the management of dentofacial anomalies and treating malocclusions. The application of undifferentiated stem cells (SCs), including signaling molecule control and individualized tissue engineering based on targeted therapies, has been proposed to overcome therapeutic limitations and complications associated with treatments for craniofacial defects, including severe orthodontic discrepancies. This scoping, prospective review discusses comprehensively the current knowledge and prospects for improving clinical outcomes by the application of novel cell-required and cell-free regenerative strategies in biomedicine. The existing evidence, although scant, suggests that patients receiving an orthodontic treatment could benefit from precise tissue augmentation, allowing enhancement of tooth movement generated by orthognathic forces; faster, more predictable alignment of dental arches; optimal management of periodontal complications; and prevention of external root resorption. Ultimately, enriching orofacial tissues and "customizing" the repair of congenital/acquired defects in the craniofacial region can be vastly enhanced to provide a positive therapeutic outcome and improve patients' quality of life.

Preliminary Assessment of the Quality of Life and Daily Burden of Caregivers of Persons with Special Needs: A Questionnaire-Based, Cross-Sectional Survey.

Caregivers of persons with special needs (PSN) experience a variety of burdens and elevated levels of stress and anxiety throughout their lives, leading to a physical, psychological, emotional, social, and financial overload. This analytical study with a cross-sectional design and a quantitative approach aimed to appraise quality of life (QoL), reflecting the daily workload of informal family caregivers of PSN. METHODS: Four structured, validated questionnaires were utilised: sociodemographic, WHOQOL-bref, Zarit Burden Interview, and Functional Independence Measure Scale in 60 anonymous volunteered respondents. RESULTS: The informal caregivers were middle-aged mothers (81.7%), married (55%), stay-at-home spouses (60%) with high school degrees (51.6%), providing a care for their relatives with special needs for more than 20 years (41.8%). Most of the PSN were diagnosed with autistic spectrum disorder (ASD, 61.8%), had a wide spectrum of intellectual deficits, and required constant support for their basic needs. They were mainly adolescent males without physical limitations (83.4%) on disorder-specific medications (90%). The study revealed that those caregivers had a median perception of QoL considering four essential domains, with a highest score recorded for the physical domain (64.3 +/- 16.1 SD). A moderate burden level prevailed, revealing neither a correlation between the workload expressed by caregivers and the patient's functional capacity, nor in the performance of daily self-care tasks (Spearman correlation test p > 0.05), apart from the environmental domain (mild correlation = 0.335, p < 0.05). CONCLUSIONS: The reported average level of overload associated with QoL of informal caregivers exists, affecting a vast proportion of the respondents. The absence of a direct association between workload and the functional capacity/daily self-care tasks can be related to the significant personal dedication of family caregivers, regardless of their socioeconomic status.

Is Periodontitis Associated with Age-Related Cognitive Impairment? The Systematic Review, Confounders Assessment and Meta-Analysis of Clinical Studies.

It has been suggested that molecular pathological mechanisms responsible for periodontitis can be linked with biochemical alterations in neurodegenerative disorders. Hypothetically, chronic systemic inflammation as a response to periodontitis plays a role in the etiology of cognitive impairment. This study aimed to determine whether periodontitis (PDS) is a risk factor for age-related cognitive impairment (ACI) based on evidence of clinical studies. A comprehensive, structured systematic review of existing data adhering to the Preferred Reporting Items for Systematic Review and Meta Analyses (PRISMA) guidelines was carried out. Five electronic databases, PubMed, Embase, Scopus, Web of Science, and Cochrane, were searched for key terms published in peer-reviewed journals until January 2021. The Newcastle-Ottawa scale was used to assess the quality of studies and risk of bias. The primary and residual confounders were explored and evaluated. A meta-analysis synthesizing quantitative data was carried out using a random-effects model. Seventeen clinical studies were identified, including 14 cohort, one cross-sectional, and two case-control studies. Study samples ranged from 85 to 262,349 subjects, with follow-up between 2 and 32 years, and age above 45 years, except for two studies. The findings of studies suggesting the PDS-ACI relationship revealed substantial differences in design and methods. A noticeable variation related to the treatment of confounders was observed. Quality assessment unveiled a moderate quality of evidence and risk of bias. The subgroups meta-analysis and pooled sensitivity analysis of results from seven eligible studies demonstrated overall that the presence of PDS is associated with an increased risk of incidence of cognitive impairment (OR = 1.36, 95% CI 1.03-1.79), particularly dementia (OR = 1.39, 95% CI 1.02-1.88) and Alzheimer's disease (OR = 1.03 95% CI 0.98-1.07)). However, a considerable heterogeneity of synthesized data (I2 = 96%) and potential publication bias might affect obtained results. While there is a moderate statistical association between periodontitis and dementia, as well as Alzheimer's disease, the risk of bias in the evidence prevents conclusions being drawn about the role of periodontitis as a risk factor for age-related cognitive impairment.

The Increasing Population Movements in the 21st Century: A Call for the E-Register of Health-Related Data Integrating Health Care Systems in Europe.

The escalating mass influx of people to Europe in the 21st century due to geopolitical and economic reasons as well as food crises ignites significant challenges for national health care services. The lack or disruption of cross-border, e-transferred, health-related data negatively affects the health outcome and continuous care, particularly in medically compromised individuals with an unsettled status. Proposal: The urgent need of a structured database, in the form of a health-related data register funded by the European Union that allows a swift exchange of crucial medical data, was discussed to flag ever-increasing migrants' health problems, with a primary aim to support an adequate health care provision for underserved people who are at risk of deteriorating health. The data security information technology aspects, with a proposed and drafted structure of an e-health register, were succinctly highlighted. Conclusions: Focusing on long-term benefits and considering future waves of mass relocation, an investment in a health-related data register in Europe could vastly reduce health care disparities between minority groups and improve epidemiological situations with regard to major illnesses, including common, communicable diseases as well as oncological and infectious conditions. Commissioners, policymakers, and stakeholders are urged to continue a collective action to ensure vulnerable people can access health services by responding to the ongoing global migration crisis.

Hepatocellular cancer cell lines, Hep-3B and Hep-G2 display the pleiotropic response to resveratrol and berberine.

PURPOSE: Human carcinoma cells with different p53 status exposed to a combination of bioactive substances, resveratrol and berberine, revealed different responses in cell viability via p53-dependant apoptosis pathway activation. MATERIALS AND METHODS: Using 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay, we investigated various and opposing effects in hepatocellular carcinoma cells, Hep-G2 and Hep-3B with different p53-status. RESULTS: Cells decreased in viability after treatment with dose-dependent concentrations of resveratrol and berberine. Hep-3B p53 mutants were more sensitive in comparison to the p53 wild type Hep-G2 cell line. A synergistic effect was observed after treatment of Hep-3B cells with a combination of resveratrol/berberine ratios in favor of resveratrol (2:1, 3:1). The results suggest that an effective concentration of berberine, in the presence of resveratrol, could be decreased even to 50% (half the IC50 for berberine) in cancer treatment. Combined treatment with berberine and resveratrol, at the investigated concentrations and fractions, significantly reduces the viability of wild type p53 Hep-G2 and null p53-mutant Hep-3B cells by 20% and 40%, respectively. CONCLUSIONS: Stronger toxic effects on viability and proliferation were observed in Hep-3B cells what is consistent with the assumptions that null p53-mutants activate apoptosis canonical pathway. In conclusion, p53 status in human hepatocellular cancer cell lines modulates responses to plant-derived therapies.

COVID-19 vaccine booster hesitancy (VBH) of healthcare professionals and students in Poland: Cross-sectional survey-based study.

Since healthcare professionals (HCPs) play a critical role in shaping their local communities' attitudes toward vaccines, HCPs' beliefs and attitudes toward vaccination are of vital importance for primary prevention strategies. The present study was designed as a cross-sectional survey-based study utilizing a self-administered questionnaire to collect data about COVID-19 vaccine booster hesitancy (VBH) among Polish HCPs and students of medical universities (MUSs). Out of the 443 included participants, 76.3% were females, 52.6% were HCPs, 31.8% were previously infected by SARS-CoV-2, and 69.3% had already received COVID-19 vaccine booster doses (VBD). Overall, 74.5% of the participants were willing to receive COVID-19 VBD, while 7.9 and 17.6% exhibited their hesitance and rejection, respectively. The most commonly found promoter for acceptance was protection of one's health (95.2%), followed by protection of family's health (81.8%) and protection of community's health (63.3%). Inferential statistics did not show a significant association between COVID-19 VBH and demographic variables, e.g., age and gender; however, the participants who had been previously infected by SARS-CoV-2 were significantly more inclined to reject the VBD. Protection from severe infection, community transmission, good safety profile, and favorable risk-benefit ratio were the significant determinants of the COVID-19 VBD acceptance and uptake. Fear of post-vaccination side effects was one of the key barriers for accepting COVID-19 VBD, which is consistent with the pre-existing literature. Public health campaigns need to highlight the postulated benefits of vaccines and the expected harms of skipping VBD.

Osteopathic Manipulative Treatment for Pediatric Conditions: An Update of Systematic Review and Meta-Analysis.

Osteopathic manipulative treatment (OMT) continues to be used for a range of diseases in children. OBJECTIVES: The aim of this paper is to update our previous systematic review (SR) initially published in 2013 by critically evaluating the evidence for or against this treatment. METHODS: Eleven databases were searched (January 2012 to November 2021). STUDY SELECTION AND DATA EXTRACTION: Only randomized clinical trials (RCTs) of OMT in pediatric patients compared with any type of controls were considered. The Cochrane risk-of-bias tool was used. In addition, the quality of the evidence was rated using Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria, as recommended by the Cochrane Collaboration. RESULTS: Thirteen trials met the eligibility criteria, of which four could be subjected to a meta-analysis. The findings show that, in preterm infants, OMT has little or no effect on reducing the length of hospital stay (standardized mean difference (SMD) -0.03; 95% confidence interval (CI) -0.44 to 0.39; very low certainty of evidence) when compared with usual care alone. Only one study (8.3%) was judged to have a low risk of bias and showed no effects of OMT on improving exclusive breastfeeding at 1 month. The methodological quality of RCTs published since 2013 has improved. However, adverse effects remain poorly reported. CONCLUSIONS: The quality of the primary trials of OMT has improved during recent years. However, the quality of the totality of the evidence remains low or very low. Therefore, the effectiveness of OMT for selected pediatric populations remains unproven.
