Homologous equivalence study of immunogenicity after third dose of Covid-19 vaccine (recombinant) with an interval of six months after the second dose, comparing the interval of eight and 12 weeks between the first two doses.

BACKGROUND: In response to the coronavirus disease 2019 (Covid-19) pandemic, Brazil authorised the Astra Zeneca/Fiocruz vaccine in January 2021. As the Delta variant emerged in May 2021, interval between vaccine doses was adjusted. By September 2021, the Brazilian National Immunisation Program recommended a booster dose for individuals over 70, and later expanded the recommendation to all adults. OBJECTIVES: Assess the equivalence of IgG antibody response against the Covid-19 S protein before and approximately 28 days after the third dose of a Covid-19 recombinant vaccine. Two groups received initial two doses with intervals of eight and 12 weeks. METHODS: This is a phase IV clinical study, uncontrolled, non-randomised. The study proposes calculating the ratio of geometric means titres (GMT) 28 days after the third dose, with a target ratio of confidence interval (CI) between 0.77 and 1.3. FINDINGS: In the primary endpoint, there was no equivalence between the eight- and 12-week intervals with a slight variation favouring the eight-week group. Post-third dose, both groups showed increases titres at 28 days, three months, six months and 12 months. Both groups responded similarly to Delta and Omicron BA.1, with a more significant increase for Delta. MAIN CONCLUSIONS: The study showed strong and consistent immune response in all age groups receiving the Covid-19 recombinant vaccine. Third dose elicited an increase in GMT by at least three times aligned with Ministry of Health strategies emphasising Bio-Manguinhos crucial role in pandemic control in the country.

Applications of MALDI mass spectrometry in forensic science.

Forensic chemistry literature has grown exponentially, with many analytical techniques being used to provide valuable information to help solve criminal cases. Among them, matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS), particularly MALDI MS imaging (MALDI MSI), has shown much potential in forensic applications. Due to its high specificity, MALDI MSI can analyze a wide variety of compounds in complex samples without extensive sample preparation, providing chemical profiles and spatial distributions of given analyte(s). This review introduces MALDI MS(I) to forensic scientists with a focus on its basic principles and the applications of MALDI MS(I) to the analysis of fingerprints, drugs of abuse, and their metabolites in hair, medicine samples, animal tissues, and inks in documents.

Assessment of the Efficacy and Durability of IncobotulinumtoxinA in the Treatment of the Upper Face in Adult Women.

INTRODUCTION: IncobotulinumtoxinA (Xeomin®) is used in the treatment of dynamic wrinkles and the aesthetic repositioning of facial structures. The duration of its muscular effect typically extends for around 4 months. However, the residual aesthetic benefit can be observed for a longer period. To date, the long-term aesthetic benefit of incobotulinumtoxinA in facial aesthetics has not been systematically evaluated. This study aimed to evaluate longitudinally the duration and aesthetic benefits of incobotulinumtoxinA in the treatment of the upper face in adult women. METHODS: A quasi-experimental, evaluator-blind, clinical trial involving 28 adult women (30-60 years old) with facial movement lines, undergoing treatment of the upper face with incobotulinumtoxinA by two injectors, following an individualized protocol (ONE21 and glabellar contraction patterns) was performed. Participants were evaluated on the day of the intervention (day 0) and days 30, 120, 180, and 240, and subjected to standardized photographs. The following outcomes were evaluated blindly at each visit: Merz Aesthetics Facial Contraction Scale (MAS), GAIS (Global Aesthetic Improvement Scale), and patient satisfaction. Adverse effects were evaluated at each visit. RESULTS: Participants ranged in age from 30 to 60 years, 93% were self-declared white, and most of their baseline MAS scores for dynamic lines were moderate and severe. All the parameters presented significative reduction from baseline until day 180. At day 240, the dynamic MAS scores were lower than baseline for forehead lines in 15.4% (95% confidence interval (CI) 0.8-30.0%) of the participants, for glabellar lines in 38.5% (95% CI 18.8-58.1%), and for crow's feet lines in 26.9% (95% CI 9.0-44.8%). Aesthetic improvement compared to baseline was identified in 35% (CI 95% 23‒50%) of the participants at day 240, and 62% (CI 95% 42‒81%) of the sample kept reporting some satisfaction with the procedure. CONCLUSION: The aesthetic treatment of the upper face with incobotulinumtoxinA demonstrates enduring clinical benefits, and patient satisfaction lasting up to 180 days in most participants. The length of efficacy, which exceeded those reported in the literature, may be attributed to the use of techniques based on individualized assessment such as ONE21 and glabellar patterns of contraction.

Bariatric surgery: behavioral patterns and personality disorders in the preoperative period

Introduction: Bariatric surgery has become an increasingly common procedure, especially for patients with morbid obesity who have obtained unsatisfactory results from conventional treatments. Objective: To evaluate the occurrence of behavioral patterns and personality disorders in patients in the preoperative period of bariatric surgery. Materials and methods: Cross-sectional study carried out with 146 patients from a medium-sized clinic, a reference in the execution of bariatric surgeries in the Midwest region of Minas Gerais, Brazil. Data collection was performed using the psychological instrument entitled Factorial Personality Battery. Descriptive analysis and data association were performed. Results: Half of the participants presented high or very high scores for greater propensity to develop depression and anxiety, showing a close relationship with personality disorders, especially with behavioral patterns of effort and dedication. Discussion: The patterns of effort and dedication behavior are protective factors in the postoperative period, taking into account the adaptations and new habits necessary for a good recovery and maintenance of weight loss. Conclusions: The dysfunctional patterns of behavior that stood out most are related to greater difficulty in perceiving the positive side and ease in perceiving the negative side, leading to a more intense experience of suffering, in addition to difficulty in making decisions and facing routine challenges. Screening behavioral patterns and personality disorders preoperatively is necessary for adequate patient monitoring and successful bariatric surgery.

Promising AAV.U7snRNAs vectors targeting DMPK improve DM1 hallmarks in patient-derived cell lines.

Myotonic dystrophy type 1 (DM1) is the most common form of muscular dystrophy in adults and affects mainly the skeletal muscle, heart, and brain. DM1 is caused by a CTG repeat expansion in the 3'UTR region of the DMPK gene that sequesters muscleblind-like proteins, blocking their splicing activity and forming nuclear RNA foci. Consequently, many genes have their splicing reversed to a fetal pattern. There is no treatment for DM1, but several approaches have been explored, including antisense oligonucleotides (ASOs) aiming to knock down DMPK expression or bind to the CTGs expansion. ASOs were shown to reduce RNA foci and restore the splicing pattern. However, ASOs have several limitations and although being safe treated DM1 patients did not demonstrate improvement in a human clinical trial. AAV-based gene therapies have the potential to overcome such limitations, providing longer and more stable expression of antisense sequences. In the present study, we designed different antisense sequences targeting exons 5 or 8 of DMPK and the CTG repeat tract aiming to knock down DMPK expression or promote steric hindrance, respectively. The antisense sequences were inserted in U7snRNAs, which were then vectorized in AAV8 particles. Patient-derived myoblasts treated with AAV8. U7snRNAs showed a significant reduction in the number of RNA foci and re-localization of muscle-blind protein. RNA-seq analysis revealed a global splicing correction in different patient-cell lines, without alteration in DMPK expression.

Risk of bleeding in anticoagulated patients undergoing dental extraction treated with topical tranexamic acid compared to collagen-gelatin sponge: Randomized clinical trial.

This two-arm, parallel-group, double-blind, randomized clinical trial design evaluated the risk of postoperative bleeding in anticoagulated patients undergoing dental extraction treated with topical TXA in comparison to collagen-gelatin sponge. Forty patients were randomly included in one of the study groups: (1) topical use of 4.8% TXA solution; and (2) resorbable hydrolyzed collagen-gelatin sponge applied to the surgical alveolus. Primary outcomes were postoperative bleeding episodes and secondary outcomes were thromboembolic events and postoperative INR values. The relative risk (RR), the absolute risk reduction (RAR) and the number needed to treat (NNT) were used as effect estimates and calculated from the counting of bleeding episodes observed during the first postoperative week. The bleeding rate under the TXA treatment was 22.2%, while in the collagen-gelatin sponge group it was 45.7%, resulting in a RR of 0.49 (95% CI 0.24-099; p = 0.046), RAR 23.5% and NNT 4.3. TXA was more effective in reducing bleeding in surgical sites located in the mandible (RR = 0.10; 95% CI 0.01-0.71; p = 0.021) and the posterior region (RR = 0.39; 95% CI 0.18-0.84; p = 0.016). Within the limitations of the study it seems that topical TXA is more effective in controlling bleeding after tooth extractions in anticoagulated patients than collagen-gelatin sponge. CLINICAL TRIAL REGISTRATION: RBR-83qw93.

Natural and Synthetic Peptides to Control Drug-resistant Pathogens.

Due to the excessive and inappropriate use of antibiotics in farming and clinic, pathogens developed resistance mechanisms to currently used drugs. Thus, because of this resistance, drugs become ineffective, leading to public health problems worldwide. According to the World Health Organization (WHO), microbial resistance to drugs is one of the most threats that humanity must face. Therefore, it is imperative to seek alternative methods to overcome microbial resistance. Here, the potential of natural or synthetic antimicrobial peptides to overcome microbial resistance will be discussed, and how peptides could be a source for new therapeutics molecules. In this context, antimicrobial peptides (natural or synthetic) are considered promising molecules based on their antifungal, antiviral, and antibacterial properties, making them eligible for developing new drugs. In addition, they can act synergistically with existing drugs on the market, revealing a broad spectrum of applications.

Sexualidade e gênero: o que pensam os adolescentes? O papel da escola e sociedade na visão de adolescentes sobre a temática

Este trabalho tem por objetivo analisar a percepção dos alunos, bem como as práticas educativas nas escolas quanto à abordagem dos temas sexualidade e gênero com adolescentes do nono ano do Ensino Fundamental. Para isto, foi feito um estudo qualitativo, com dez estudantes, entre 13 e 15 anos, em escolas públicas estaduais de uma cidade do Centro-Oeste Mineiro. A pesquisa foi realizada entre setembro e dezembro de 2019. Para a coleta de dados, foi utilizado um roteiro semiestruturado, confeccionado pelos próprios pesquisadores, contendo questões acerca do conhecimento dos jovens sobre sexualidade e gênero, preconceito, violência e a forma como o tema é abordado no ambiente escolar. A análise utilizou o referencial teórico-metodológico da hermenêuticadialética. Os resultados demonstraram um desconhecimento dos estudantes no que concerne à conceituação de gênero e orientação sexual. No que diz respeito à abordagem das escolas referente ao assunto, observou-se ainda uma visão biologicista e uma dificuldade em dialogar com os adolescentes sobre suas dúvidas e posicionamentos. A maioria dos participantes também relatou ter sofrido ou presenciado preconceito contra mulheres ou devido à orientação sexual. Por fim, os achados deste estudo indicaram a necessidade de reflexão sobre o paradigma dominante da educação sexual nas escolas, como também a necessidade de superar os tabus e construir uma abordagem mais multidisciplinar, abrangente e inclusiva, que respeite a autonomia dos adolescentes em relação à sua sexualidade.

Hospital Dermatology: analysis of dermatological consultations in a tertiary teaching hospital.

BACKGROUND: In hospital settings, dermatology can offer substantial clinical support for the diagnosis and management of skin conditions, reducing morbidity and mortality. Thus, the study aimed to analyze the profile of referrals and consultations performed by the Dermatology Service of the Santa Casa de Misericordia de Porto Alegre, from August 2018 to January 2020. METHODS: This study is descriptive, quantitative, and retrospective, conducted through data collection and review of medical records and referrals. The variables included were clinical data of referrals, in-patients profiles, dermatological diagnoses, complementary exams, therapeutic conduct, and recommended follow-ups. RESULTS: A total of 1020 referrals were analyzed, which resulted in 641 consultations (328 men, 313 women). The most prevalent skin disease groups were 'Dermatitis and Eczema' (33.1%) and 'Other infectious skin diseases (21.8%), while the most frequent ICD-10 were 'Drug eruptions - L27' (9.9%) and 'Other and unspecified dermatitis - L30' (6.6%). Corticoids were the most recommended treatments (27.7%), followed by antifungals (13.1%). 'Consultation Discharge' (44%) and 'Outpatient' Dermatology follow-up (27%) were the most frequent causes for ending consultation. STUDY LIMITATIONS: Among the study limitations, the authors highlight its retrospective nature, with data analysis based on referrals and medical records, which may present inaccurate or incomplete information. In addition to this, the study may demonstrate a certain degree of subjectivity due to the review and interpretation process conducted by the researchers. However, the definition of objective criteria based on previous studies attenuates such possible bias. Furthermore, considering that the Dermatology teams are composed of a preceptor dermatologist and residents, the established diagnoses were not submitted to third-party verification, except in the cases of skin biopsies and cultures. Thus, the professional's experience and skills may have influenced the dermatological diagnoses. CONCLUSIONS: These findings underlie the importance of Dermatology in hospital assistance, contributing to the management of a wide range of skin conditions.

Efficacy and Tolerability of Hyperdiluted Calcium Hydroxylapatite (Radiesse) for Neck Rejuvenation: Clinical and Ultrasonographic Assessment.

Background: The subdermal injection of calcium hydroxylapatite (CaHA) can improve the mechanical properties of the skin, providing immediate correction and stimulating the endogenous production of collagen, elastin, angiogenesis, and dermal cell proliferation; however, few studies have examined the neck region. Purpose: This study assessed the clinical and ultrasonographic improvement induced by two sessions of subdermal injection of hyperdiluted (1:4) CaHA for neck rejuvenation in 22 women. Patients and Methods: A quasi-experimental longitudinal trial (before and after) was performed by enrolling 22 adult women with mild and moderate neck aging (grades 1 and 2) on Merz Neck Volume Scale at rest (laxity) and Neck Horizontal Lines. They were submitted to two sessions of subdermal hyperdiluted CaHA (D0 and D45) treatments and assessed clinically and ultrasonographically at D0, D45, and D120. The main outcomes were the blinded photographic assessment (Merz scales of neck laxity and horizontal lines), dermal thickness (at three points), and the GAIS (Global Aesthetic Improvement Scale) score. Results: The mean (SD) age was 43.5 (5.6) years. At the inclusion, the Merz scores for neck laxity were mild for 27% and moderate for 73% of participants, and the Merz scores for necklines were mild for 32% and moderate for 68%. At D120, scores decreased in 86% (95% CI 68-99%) of the participants by at least one degree on the necklines scale and in 82% (95% CI 73-90%) for neck laxity. According to the GAIS, 91% (95% CI 77-99%) of the participants evidenced improvement at D120. The mean dermal thickness increased by 15% (95% CI 8-21%) at D120. No severe adverse effects were recorded, and high satisfaction was reported by 82% of the participants. Conclusion: Two sessions of subdermal hyperdiluted CaHA were well-tolerated and improved necklines, neck laxity, and dermal thickness in adult women with mild and moderate cervical aging.

Prevalence of dentin hypersensitivity after orthodontic treatment: A cross-sectional study.

INTRODUCTION: The prevalence of cervical dentin hypersensitivity in patients after corrective orthodontic treatment has been poorly studied, although such hypersensitivity is very common. This study aimed to assess the prevalence of dentin hypersensitivity in patients who received corrective orthodontic treatment, the impact of general oral problems on quality of life, and the impact of hypersensitivity on the quality of life of this population. METHODS: This observational, cross-sectional study evaluated 232 patients who finished orthodontic treatment between 2000 and 2020 for self-reported hypersensitivity and clinically diagnosed hypersensitivity. The following tests were used: tactile, evaporative (bellows), evaporative (triple syringe), and thermal. The patients were also evaluated regarding their quality of life using questionnaires (Oral Health Impact Profile-14 and Dentine Hypersensitivity Experience Questionnaire). We evaluated data with nonparametric statistics. RESULTS: The prevalence of hypersensitivity was higher in women and in those aged <30 years; the most affected teeth were the mandibular incisors and premolars; different diagnostic tests for hypersensitivity may indicate different prevalence values; patients with hypersensitivity had a lower quality of life in most of the domains of both of the tests that were used. CONCLUSIONS: The prevalence of hypersensitivity among patients after orthodontic treatment may be higher than in the general population. Further investigation is needed to indicate the possible factors associated with orthodontic tooth movement.

Predicted Bezlotoxumab Exposure in Patients Who Have Received a Hematopoietic Stem Cell Transplant.

PURPOSE: Bezlotoxumab is approved for prevention of recurrent Clostridioides (Clostridium) difficile infection (CDI) in adults receiving antibacterial treatment for CDI who are at high risk for recurrent CDI. Previous studies have shown that although serum albumin levels are an important predictor for bezlotoxumab exposure, this has no clinically meaningful impact on efficacy. This pharmacokinetic modeling study assessed whether hematopoietic stem cell transplant (HSCT) recipients, at increased risk of CDI and exhibiting decreased albumin levels within the first month posttransplant, are at risk of clinically relevant reductions in bezlotoxumab exposure. METHODS: Observed bezlotoxumab concentration-time data pooled from participants in Phase III trials MODIFY I and II (ClinicalTrials.gov identifiers NCT01241552/NCT01513239) and three Phase I studies (PN004, PN005, and PN006) were used to predict bezlotoxumab exposures in two adult post-HSCT populations: A Phase Ib study of posaconazole including allogeneic HSCT recipients (ClinicalTrials.gov identifier NCT01777763; posaconazole-HSCT population); and a Phase III study of fidaxomicin for CDI prophylaxis (ClinicalTrials.gov identifier NCT01691248; fidaxomicin-HSCT population). The bezlotoxumab PK model used the minimum albumin level for each individual in post-HSCT populations to mimic a "worst-case scenario." FINDINGS: Predicted worst-case bezlotoxumab exposures for the posaconazole-HSCT population (N = 87) were decreased by 10.8% versus bezlotoxumab exposures observed in the pooled Phase III/Phase I data set (N = 1587). No further decrease was predicted for the fidaxomicin-HSCT population (N = 350). IMPLICATIONS: Based on published population pharmacokinetic data, the predicted decrease in bezlotoxumab exposure in the post-HSCT populations is not expected to have a clinically meaningful effect on bezlotoxumab efficacy at the recommended 10 mg/kg dose. Dose modification is therefore not required in the hypoalbuminemia setting expected post-HSCT.

Vitamin D-Dependent Rickets Type 3: A Case Report and Systematic Review.

Although vitamin D deficiency resulting from insufficient sunlight exposure or inadequate dietary vitamin D intake is the most common cause of rickets, mutations in genes involved in vitamin D metabolism can cause genetic forms of rickets termed Vitamin D-Dependent Rickets (VDDR). In 2018, Roizen et al. described a new type of VDDR, named VDDR3, caused by a recurrent missense mutation in the CYP3A4 gene that leads to accelerated inactivation of vitamin D metabolites. Here, we describe the third case of VDDR3 due to the same CYP3A4 mutation in a 2-year-old boy with bone deformities associated with poor growth. As in the previously reported cases, this patient had no family history of rickets. Serial measurements of vitamin D metabolites after a single 150,000 IU dose of cholecalciferol demonstrated an accelerated inactivation of 25(OH)D and 1,25(OH)2D. Significant improvement in growth velocity and healing of bone deformities were achieved after a short period of treatment with 10.000 IU of cholecalciferol daily, showing the importance of early recognition and prompt precision therapy of this condition.

Model-Informed Dose Justifications of Posaconazole in Japanese Patients for Prophylaxis and Treatment Against Fungal Infection.

Posaconazole is a globally approved broad-spectrum triazole antifungal compound. In Japanese patients, posaconazole has identical dosing regimens as those approved globally for both tablet and intravenous formulations. This article aims to describe a model-informed approach for dose justification of posaconazole in the Japanese population as either high-risk patients with fungal infections (prophylaxis patients) or patients with fungal infections (treatment patients). A simultaneous population pharmacokinetic (PK) model for tablet and intravenous formulation was developed on the basis of a data set including Japanese data from healthy participants and treatment patients. The PK profiles and exposure distributions in Japanese patients were predicted and compared against foreign patients, that is, patients outside of Japan. Relationships between the post hoc posaconazole exposures and frequently observed clinical adverse events were evaluated. Although clinical trials for Japanese prophylaxis patients were not conducted, PK profiles in Japanese prophylaxis patients were predicted using the population PK model and demographic covariate information obtained from the published literature. Based upon the globally approved dosing regimen, posaconazole exposure distribution was predicted to be the highest in Japanese treatment patients, and generally similar between Japanese and foreign prophylaxis patients. Exposures in Japanese patients exceeded the efficacy target level (500 ng/mL). Safety profiles in Japanese treatment patients with the highest exposures were clinically acceptable without specific concerns to Japanese patients and appeared to have no relationship with posaconazole exposures. From PK, safety, and efficacy perspectives, the use of the same dosing regimen as in foreign patients was justified in Japanese prophylaxis and treatment patients.
