RESUMEN
Investigation of the biological sex of human remains is a crucial aspect of physical anthropology. However, due to varying states of skeletal preservation, multiple approaches and structures of interest need to be explored. This research aims to investigate the potential use of distances between bifrontal breadth (FMB), infraorbital foramina distance (IOD), nasal breadth (NLB), inter-canine width (ICD), and distance between mental foramina (MFD) for combined sex prediction through traditional statistical methods and through open-access machine-learning tools. Ethical approval was obtained from the ethics committee, and out of 100 cone beam computed tomography (CBCT) scans, 54 individuals were selected with all the points visible. Ten extra exams were chosen to test the predictors developed from the learning sample. Descriptive analysis of measurements, standard deviation, and standard error were obtained. T-student and Mann-Whitney tests were utilized to assess the sex differences within the variables. A logistic regression equation was developed and tested for the investigation of the biological sex as well as decision trees, random forest, and artificial neural networks machine-learning models. The results indicate a strong correlation between the measurements and the sex of individuals. When combined, the measurements were able to predict sex using a regression formula or machine learning based models which can be exported and added to software or webpages. Considering the methods, the estimations showed an accuracy rate superior to 80% for males and 82% for females. All skulls in the test sample were accurately predicted by both statistical and machine-learning models. This exploratory study successfully established a correlation between facial measurements and the sex of individuals, validating the prediction potential of machine learning, augmenting the investigative tools available to experts with a high differentiation potential.

Female Pattern Hair Loss (FPHL) is a common form of non-scaring hair loss that occurs in adult women. Although several treatments have already been proposed for FPHL, only Topical Minoxidil accumulated an adequate level of evidence. This study aimed to evaluate the therapeutic response of MMP® (intradermal infiltration) of Minoxidil formulation in the frontal-parietal-vertex regions compared with the gold-standard home administration of Minoxidil 5% Capillary Solution. This self-controlled comparative study evaluated 16 FPHL patients, without treatment for at least 6 months, confirmed by trichoscopy with TrichoLAB® software. They received 4 monthly sessions of MMP® with Minoxidil 0,5% on the right side of the scalp (frontal-parietal-vertex areas), followed by occlusion with plastic film for 12 h and prescription of Minoxidil 5% Solution for home use once a day, on both scalp sides, starting 72 h after the procedure. The reassessment trichoscopy was 6 weeks after the last session and they answered a "self-assessment" questionnaire. Treated scalp areas were compared and showed both treatments, in general, were effective, with no difference between them. If they were analyzed separately by treated areas, there were signs of better response in the parietal-vertex regions with treatment by MMP® with Minoxidil, while clinical treatment indicated a better response in the other regions. When patients were divided into more and less advanced cases, a better response in parietal-vertex regions treated by MMP® with Minoxidil in less advanced patients was confirmed. MMP® with Minoxidil showed a better response in the parietal-vertex regions in less advanced FPHL patients. It represents yet another resource to improve quality of life of these suffering patients.

O objetivo do presente estudo foi revisar a literatura para buscar evidências na associação entre a doença de Alzheimer e a Periodontite. A metodologia usada resultou numa busca às bases de dados PubMed/MEDLINE, Cochrane Library e Web of Science, através dos artigos publicados entre o período de maio de 2000 a maio de 2022. A doença de Alzheimer (DA) é classificada como uma condição neurodegenerativa, um grupo heterogêneo de doenças caracterizadas pela perda lenta e progressiva de uma ou mais funções do sistema nervoso. A doença periodontal (DP) é uma doença infecciosa e inflamatória que causa principalmente destruição óssea alveolar e perda dentária e estima-se que entre 20 e 50% da população geral possa sofrer de DP, dos quais 15-20% apresentam formas graves. A inflamação desempenha um papel crítico no aparecimento e progressão de ambas as doenças. A conclusão desta revisão é que a literatura estudada mostra que os patógenos periodontais e as citocinas pró-inflamatórias contribuíram para a progressão do processo neurodegenerativo da doença de Alzheimer. Porém, são necessários mais estudos clínicos controlados randomizados para a confirmação da relação causal desta associação.
The aim of this study was to review the literature to look for evidence in the association between Alzheimer's disease and Periodontitis. The methodology used resulted in a search of the PubMed/MEDLINE, Cochrane Library and Web of Science databases, through the articles published between May 2000 and May 2022. Alzheimer's disease (AD) is classified as a neurodegenerative condition, a heterogeneous group of diseases characterized by the slow and progressive loss of one or more functions of the nervous system. Periodontal disease (PD) is an infectious and inflammatory disease that mainly causes alveolar bone destruction and tooth loss and it is estimated that between 20 and 50% of the general population may suffer from PD, of which 15-20% present severe forms. Inflammation plays a critical role in the onset and progression of both diseases. The conclusion of this review is that the literature studied shows that periodontal pathogens and pro-inflammatory cytokines contributed to the progression of the neurodegenerative process of Alzheimer's disease. However, more randomized controlled clinical trials are needed to confirm the causal relationship of this association.

The year 2021 marked a decade of holopelagic sargassum (morphotypes Sargassum natans I and VIII, and Sargassum fluitans III) stranding on the Caribbean and West African coasts. Beaching of millions of tons of sargassum negatively impacts coastal ecosystems, economies, and human health. Additionally, the La Soufrière volcano erupted in St. Vincent in April 2021, at the start of the sargassum season. We investigated potential monthly variations in morphotype abundance and biomass composition of sargassum harvested in Jamaica and assessed the influence of processing methods (shade-drying vs. frozen samples) and of volcanic ash exposure on biochemical and elemental components. S. fluitans III was the most abundant morphotype across the year. Limited monthly variations were observed for key brown algal components (phlorotannins, fucoxanthin, and alginate). Shade-drying did not significantly alter the contents of proteins but affected levels of phlorotannins, fucoxanthin, mannitol, and alginate. Simulation of sargassum and volcanic ash drift combined with age statistics suggested that sargassum potentially shared the surface layer with ash for ~50 d, approximately 100 d before stranding in Jamaica. Integrated elemental analysis of volcanic ash, ambient seawater, and sargassum biomass showed that algae harvested from August had accumulated P, Al, Fe, Mn, Zn, and Ni, probably from the ash, and contained less As. This ash fingerprint confirmed the geographical origin and drift timescale of sargassum. Since environmental conditions and processing methods influence biomass composition, efforts should continue to improve understanding, forecasting, monitoring, and valorizing sargassum, particularly as strandings of sargassum show no sign of abating.

Introduction: Androgenetic alopecia (AGA) is the most common alopecia affecting both genders leading to a potential decrease in quality of life and self-esteem. A current concern in trichology is how to accurately measure clinical response in both daily medical practice and academic research. Hair-to-hair (H2H)-matching technology™ has recently emerged as a technique to evaluate variations in follicular units, hair shaft number, and thickness. This study aimed to describe the methodology employed in a clinical trial using this technology to test the efficacy of botulinum toxin (BT) for male AGA. Methods: This pilot study is a triple-blind, randomized, split scalp, placebo-controlled clinical trial. Patients enrolled were submitted to injections half of the scalp with 50 IU of BT and the other half with 1 mL of normal saline as a control. The trial involved three visits (weeks 0, 12, and 24) and 8 global clinical photographs followed by H2H-matching trichoscopy were captured before the injections at each visit. Paired t test analysis was employed for matched pairs of the following parameters: total hair count, the total number of terminal hair strands, average shaft thickness, and the number of hairs lost or gained during each visit. Then, the software compared the differences between the two sides (BT vs. placebo) per scalp zone and a long time. Conclusion: The combination of manually corrected image processing, follicular map, and H2H-matching technology™ appears to be the most precise way to evaluate changes in hair count and thickness over time. The design is reproducible and can help other researchers and dermatologists in their clinical practice to obtain reliable results in similar scientific research.

Background: Trichoscopy can be very useful for evaluation for hair transplantation (HT), helping rule out simulators of androgenetic alopecia (AGA). There are only a few reports about normal trichoscopic findings after HT. Objective: The aim of this study was to evaluate donor and recipient area trichoscopy after FUE in HT without complications in AGA patients. Method: A prospective study was carried out with 10 patients, for 24 weeks, with photographic follow-up, using FotoFinder®. Patients were evaluated from week 1 (w1) to week 8 weekly, then, at week 12 and week 24 post-HT. Results: Main results were perifollicular crusts, donor area erythema, recipient area erythema, perifollicular erythema, white circles, perifollicular whitish halos, repilation black dots, dystrophic hairs, folliculitis, yellow dots. We discussed the meaning of each of these findings in the period in which they occurred. Conclusion: Normal trichoscopic findings in post-transplant patients have not been well established yet. Our findings are an attempt to define a normal pattern. Future studies with a longer follow-up may be necessary to corroborate these results.
RESUMEN
Objective We aim to describe an experimental model for studying femoral fractures in rats after exposure to ionizing radiation, demonstrating a way to apply a substance for analysis, the method for patterning fracture and irradiation, and how to evaluate its effectiveness based on radiographic studies. Methods We used 24 rats divided into 2 groups of 12 animals each. The STUDY group was exposed to ionizing radiation and treated with saline solution, and the CONTROL group was not exposed to radiation and was treated with saline solution. All animals were subjected to standardized fracture of the right femur that was fixed with intramedullary wire. The efficiency of the bone union was assessed by radiographic exam. Results Fracture healing was more efficient in bones not exposed to ionizing radiation ( p = 0.012). All fractures met the criteria of being simple, diaphyseal, transverse or short oblique. Conclusion The experimental model presented is an efficient alternative for the study of fractures in irradiated bones in rats.

Resumo Objetivo Nosso objetivo é descrever um modelo experimental para estudo de fraturas de fêmur em ratos após exposição a radiação ionizante, demonstrando uma forma de aplicação de uma substância para análise, o método de padronização de fratura e irradiação e a forma de avaliação de sua eficácia com base em estudos radiográficos. Métodos Utilizamos 24 ratos divididos em dois grupos de 12 animais cada. O grupo ESTUDO foi exposto à radiação ionizante e tratado com soro fisiológico, enquanto o grupo CONTROLE não foi exposto à radiação e foi tratado com soro fisiológico. Todos os animais foram submetidos à fratura padronizada do fêmur direito e sua fixação com fio intramedular. A eficácia da consolidação óssea foi determinada por exame radiográfico. Resultados A cicatrização de fraturas foi mais eficiente em ossos não expostos à radiação ionizante (p = 0,012). Todas as fraturas atenderam aos critérios de serem simples, diafisárias, transversas ou oblíquas curtas. Conclusão O modelo experimental apresentado é uma boa alternativa para o estudo de fraturas em ossos irradiados em ratos.

Hyaluronic acid filler injections are regarded as the gold standard procedure for facial rejuvenation. Standing as the second most injected cosmetic filler, calcium hydroxyapatite-based fillers are also widely used worldwide. However, to our knowledge, prospective studies assessing patient satisfaction and sonographic changes in dermal thickness after a single session of a hybrid filler combining hyaluronic acid and calcium hydroxyapatite have not been previously published. Methods: This was a single-center, prospective, quasi-experimental study comprising 15 participants between 32 and 63 years of age. Each participant received a single-session treatment based on facial subcutaneous injections of HArmonyCa, a hybrid combination filler comprising hyaluronic acid and calcium hydroxyapatite. This study involved an intrapatient control design and a 120-day follow-up with clinical and sonographic assessment. For this purpose, standardized photographic images, high-frequency ultrasound evaluations, and physician- and patient-oriented overall aesthetic improvement scores were recorded at 0, 30, 90, and 120 following the procedure. Results: According to our findings, 20% of the subjects had an exceptional improvement; 20%, "very improved"; and 60%, "improved." Intrapatient sonographic comparison showed a significant increase in dermal thickness, at 90 and 120 days, only on the side treated (P < 0.001). Conclusion: In our clinical study, a single-session treatment with a hybrid product combining hyaluronic acid and calcium hydroxyapatite resulted in positive cosmetic satisfaction and increased dermal thickness.
RESUMEN
A Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde (CID) é uma forma globalmente padronizada para fornecer informações cruciais sobre as doenças, suas causas e consequências, colaborando para criar políticas de saúde e laborais. Porém, sua divulgação compulsória por parte de profissionais da saúde pode expor o empregado e sua privacidade. Neste contexto, o objetivo desse trabalho é analisar as decisões publicadas nos últimos dez anos, julgadas em última instância pelo Tribunal Superior do Trabalho (TST) e o entendimento dos magistrados sobre o assunto, as leis utilizadas no embasamento e a distribuição dos processos com esse teor. Foi realizada uma pesquisa no site do TST com os termos "exigência" "CID" "atestado" "médico" entre os anos de 2012 e 2022. Foram encontradas 18 decisões, 94% delas das regiões Sul e Sudeste do país. Quase 70% são desfavoráveis à exigência da CID em atestados, tendo como base a Constituição Federal (CF), resoluções do Conselho Federal de Medicina (CFM) e o Código Civil (CC). Conclui-se que as decisões relacionadas à exigência do código da CID estão concentradas em tribunais do Sul e do Sudeste, sendo os anos entre 2015 e 2019 com o maior número de ocorrências. Há uma predominância pela não exigência do código da CID em 12 das 18 decisões, sendo o argumento mais utilizado o sigilo e privacidade garantidos pela CF e Códigos de Ética Médica e de Ética Odontológica. As que se mostraram a favor predominantemente citam a súmula 122 do TST
International Statistical Classification of Diseases and Health Related Problems (ICD) is the global standard for diagnostic health information, providing key information about diseases, their causes, and consequences, leading to improvement on public and labor health. Its disclosure may expose employers when required by employers. Based on this context, the aim of this study is to analyze decisions law decisions and judgments reports from the Federal Labor Court between 2012 and 2022, the understanding of judges on the subject, the basis and distribution of decisions in this matter. Research was conducted on Superior Labor Court of Brazil website, using the keywords in Portuguese "requirement", "ICD", "statement" and "medical" between 2012 and 2022. It was found 18 judgments, 94% from South and Southeast of Brazil. Almost 70% of them were against the requirement of ICD code in medical statement, basing their decisions on our Federal Constitution (FC), resolutions of the Federal Medical Council (FMC) and Civil Code (CC). In conclusion, the Brazilian Law understands that the employee's privacy when seeking for medical help is above the employer's requirement. It is believed the new General Data Protection Law (GDPL) may reinforce this common Legal Knowledge and help footing new orders
RESUMEN
The use of mixed mineral fertilizers consisting of macro- and micronutrients, which are already routinely used for leaf fertilization, in the treatment of corn and soybean seeds would positively influence germination and vigor, consequently improving growth and seedling development. This study aimed to evaluate the physiological potential of corn and soybean seeds treated with mixed mineral fertilizers. The seed treatment efficiency test with mixed mineral fertilizers was conducted at the Federal University of Jataí-UFJ-using Vital®, Lança®, Ídolo®, Massivo®, and their combinations. The treatments consisted of two controls for soybean and three for corn. Analysis of variance was performed using the F-test (p ≤ 0.05), and when there was significance, the means were compared using the Scott-Knott test (p ≤ 0.05). The mixed mineral fertilizers Vital® + Massivo® (T6), Lança® + Ídolo® (T7), and Vital® + Lança® + Ídolo® (T10) used in the seed treatment benefit the development of soybean (NS7667 IPRO) seeds. The treatments for corn (MG744 PWU) had little effect on germination and seedling development. The use of mixed mineral fertilizers in the seed treatments did not affect the physiological potential of the soybean and corn seeds, keeping the lots with germination values within commercialization standards.
