Morphometric Analysis of the Mandibular Canal and Its Anatomical Variants in a Chilean Subpopulation: Cone Beam Computed Tomography Study.

The inferior alveolar nerve (IAN), contained within the mandibular canal (MC), is a structure prone to damage in clinical and surgical procedures on the mandible. This study aimed to analyze the MC morphology and its anatomical variants in a Chilean subpopulation using cone beam computed tomography (CBCT). In total, 342 images from patients with the following parameters were observed: 120 kV, 9 mA, field of view 12 × 9 MC, and voxel size 0.12 mm. The average length of the MC recorded a mean value of 70.493 ± 4.987 mm on the right side and 70.805 ± 5.177 mm on the left side. The location of the mental foramen (MF) was most frequently found between the mandibular first and second premolar. The greatest bone thickness was found at the level of the basilar border of the 2MPM. The root closest to the MC was distal from the mandibular second molar. The lowest thickness was in the lingual area at 1MM. The prevalence of the anterior loop (AL) (61.5%) and the retromolar canal (RC) (17.5%) showed no significant differences between men and women. The results obtained showed that the morphology of the MC in the Chilean subpopulation can vary.

Multimodal neuroimaging in Long-COVID and its correlates with cognition 1.8 years after SARS-CoV-2 infection: a cross-sectional study of the Aliança ProHEpiC-19 Cognitiu.

Introduction: There is a growing interest in the effect of Long-COVID (LC) on cognition, and neuroimaging allows us to gain insight into the structural and functional changes underlying cognitive impairment in LC. We used multimodal neuroimaging data in combination with neuropsychological evaluations to study cognitive complaints in a cohort of LC patients with mild to moderate severity symptoms. Methods: We conducted a 3T brain magnetic resonance imaging (MRI) study with diffusion tensor imaging (DTI) and functional MRI (fMRI) sequences on 53 LC patients 1.8 years after acute COVID-19 onset. We administered neuropsychological tests to evaluate cognitive domains and examined correlations with Tract-Based Spatial Statistics (TBSS) and resting state. Results: We included 53 participants with LC (mean age, 48.23 years; 88.7% females). According to the Frascati criteria, more than half of the participants had deficits in the executive (59%) and attentional (55%) domains, while 40% had impairments in the memory domain. Only one participant (1.89%) showed problems in the visuospatial and visuoconstructive domain. We observed that increased radial diffusivity in different white matter tracts was negatively correlated with the memory domain. Our results showed that higher resting state activity in the fronto-parietal network was associated with lower memory performance. Moreover, we detected increased functional connectivity among the bilateral hippocampus, the right hippocampus and the left amygdala, and the right hippocampus and the left middle temporal gyrus. These connectivity patterns were inversely related to memory and did not survive false discovery rate (FDR) correction. Discussion: People with LC exhibit cognitive impairments linked to long-lasting changes in brain structure and function, which justify the cognitive alterations detected.

Adolescents and Young Adults Evaluating a Website for Affective-Sexual Information and Education: Multicenter Cross-Sectional Study.

BACKGROUND: Today's young people have long been demanding a paradigm shift in the emotional and sexual education they receive. While for them, affective-sexual and gender diversity is already a reality, the sexual and reproductive health professionals they encounter lack sufficient training. The digital devices and affective-sexual education websites aimed at today's young people must also be thoroughly evaluated. The website Sexe Joves is a website on sexuality by the Department of Health of the Government of Catalonia (Spain). It is designed for people aged 14 to 25 years. It currently needs to undergo a process of evaluation. Affective-sexual education aimed at young people must stem from their participation and the whole range of sexual and gender diversity in order to reach the entire population equally. OBJECTIVE: The aim of this study was to evaluate the website Sexe Joves as a source of affective-sexual health information, education, and communication for young people. It takes into account sex, gender identity, sexual orientation, socioeconomic status, and location within Catalonia (urban, semiurban, and rural areas). METHODS: This was an observational, descriptive, and cross-sectional study that forms part of a larger mixed methods study. An ad hoc questionnaire was used to collect data. In total, 1830 participants were included. The study was carried out simultaneously in all the territorial administrations of Catalonia. RESULTS: Almost 30% of the sample obtained were young people who experience affective-sexual and gender diversity. Of those surveyed, only 14.2% (n=260) said they were familiar with the website and of these, 6.5% said they used it (n=114). The website content rated most indispensable was on sexual abuse, harassment, and violence, followed by sexually transmitted infections; 70.5% (n=1200) reported that they visit pornographic websites. CONCLUSIONS: The results of this study will contribute to the design of new strategies for the website Sexe Joves, a public health resource, in order to improve affective sexual education for young people.

In vitro comparative study between adhesion forces obtained on zirconia ceramic micromechanically treated with femtosecond laser (1027 nm), carbon dioxide laser (10,600 nm), and aluminum-oxide particles.

Conventional surface roughening treatments used for silica-based ceramics in order to improve subsequent adhesion become unreliable for zirconia ceramics. Laser conditioning can be a good alternative. The purpose of this in vitro study was to compare conventional (macro) shear bond strength (SBS) values obtained between resin composite and zirconium oxide ceramic samples grouped according to different micromechanical treatments received, and examine differences in surface roughness. One-hundred and fifty disks of sintered zirconia were randomly divided into 5 groups and roughened as follows: (1) Group NOT, no surface treatment; (2) Group APA, abraded with 50-µm aluminum-oxide (Al2O3) particles; (3) Group TBS, abraded with 30-µm aluminum-oxide particles covered with silica; (4) Group CO2, irradiated with a CO2 laser which emitted in continuous wave mode at 3 W of power; and (5) Group FEM, irradiated with a pulsed femtosecond laser, with an incident energy of 10 µJ, a frequency of 1000 Hz, and a fluence of 1.3 kJ/cm2. All surfaces were treated with a MDP-containing adhesive/silane coupling agent mixture upon which were prepared and light polymerized composite resin cylinders. Shear bond strength was measured and samples were observed by scanning electron microscopy (SEM). Statistically significant differences (p < 0.05) were found among all groups, except between CO2 and FEM, which showed the highest adhesion values (15.12 ± 2.35 MPa and 16.03 ± 2.73 MPa). SEM revealed differences in surface patterns. CO2 laser irradiation can be an alternative to sandblasting, although it could also weaken the ceramic. Suitable surface patterns on zirconia ceramics can be obtained with ultrashort pulsed radiation emitted by a pulsed femtosecond laser.

Post-endodontic pain evaluation after different intracanal laser assisted disinfection techniques. A Systematic Review.

Background: Post-endodontic pain (PEP) management is an important factor to be considered in endodontic treatment. Several risk factors have been described that can attribute to its appearance. Laser-assisted disinfection has been described by many authors for its antimicrobial effect. Few studies described the relation between laser disinfection and its effect on PEP. The objective of this review is to describe the relation between different intracanal laser disinfection techniques and their effects on PEP. Material and Methods: An electronic search strategy was performed in Pubmed, Embase, and Web of Science (WOS) databases without restrictions as to the date of publication. Eligibility criteria were randomized controlled clinical trials (RCT) that used one of the different intracanal laser disinfection techniques in their experimental groups evaluating PEP outcome were included. Risk of bias analysis was performed by the Cochrane risk of bias tool. Results: The initial research identified 245 articles from which 221 were excluded and 21 studies were sought for retrieval and 12 articles met our inclusion criteria for the final qualitative analysis. The laser systems used were Nd:YAG, Er:YAG and, diode lasers including photodynamic therapy. Conclusions: The diode lasers showed the most promising results in terms of PEP reduction while Er:YAG showed more short-term efficacy (6 hours postoperative interval). The variables could not be analyzed homogenously due to the differences in the study designs. More RCT are needed comparing different laser disinfection techniques with the same baseline endodontic pathology to establish a specific protocol for the best outcome. Key words:Root canal treatment, Post-endodontic pain, Intracanal laser disinfection, laser dentistry.

Comparative Study of Transmission of 2940 nm Wavelength in Six Different Aesthetic Orthodontic Brackets.

BACKGROUND: Previous studies have confirmed the superiority of using erbium lasers (2940, 2780 nm) over other lasers in the debonding of ceramic brackets due to their safety and effectiveness. The most important factor in the debonding of aesthetic brackets is the transmission of the erbium laser through the aesthetic bracket to the adhesive resin. OBJECTIVE: To identify the transmission of the 2940 nm wavelength through different types of aesthetic brackets. MATERIALS AND METHODS: A total of 60 aesthetic brackets were divided into six equal groups (10 monocrystalline sapphire brackets-Radiance, AO; 10 monocrystalline sapphire brackets-Absolute, Star Dentech; 10 polycrystalline brackets-20/40, AO; 10 polycrystalline brackets-3M Unitek Gemini Clear Ceramic; 10 silicon brackets-Silkon Plus, AO; 10 composite brackets-Orthoflex, OrthoTech). The aesthetic brackets were mounted in a Fourier transform infrared spectrophotometer (FTIR IRPrestige-21, SHIMADZU) following the typical spectroscopy lab procedure for such samples. The transmission ratio for the 2940 nm wavelength was obtained using IRsolution software. The mean transmission values of the tested groups were compared using a one-way analysis of variance (ANOVA) test followed by a Bonferroni test (post-hoc test). RESULTS: The highest transmission ratio was observed for the Radiance sapphire brackets (64.75%) and the lowest was observed for the 3M polycrystalline brackets (40.48%). The differences among the Aesthetic brackets were significant (p < 0.05). CONCLUSIONS: The thick polycrystalline and composite brackets have the lowest transmissibility, whereas the monocrystalline sapphire brackets have the highest transmissibility for the 2940 nm wavelength, meaning that there is a higher possibility of debonding them with a hard tissue laser through thermal ablation.

Complejidad asistencial y lugar de muerte en atención domiciliaria paliativa / Care complexity and place of death in palliative home care

Objetivo: Examinar las asociaciones entre las dimensiones del modelo de complejidad asistencial HexCom y la ubicación de la muerte. Método: Estudio observacional longitudinal multicéntrico en pacientes con enfermedad avanzada tratados por los equipos de soporte a la atención domiciliaria en Cataluña. Se recogieron edad, sexo, estado funcional y cognitivo, tipo de enfermedad, cuidador/a principal, trabajador/a familiar, lugar de la muerte y complejidad tras la primera visita. Se realizó un análisis de regresión de Cox multivariante. Resultados: Participación de 1527 pacientes (72% oncológicos), atendidos una mediana de 35 días. El 45% fallecieron en su domicilio. La probabilidad de morir en casa era mayor cuando se detectaba un mayor deterioro funcional (hazard ratio [HR]: 7,67; intervalo de confianza del 95% [IC95%]: 4,93-11,92), cuando el sujeto era varón (HR: 1,19; IC95%: 1,02-1,39), cuando la edad era >80 años (HR: 1,41; IC95%: 1,20-1,66) y cuando se detectaba complejidad en relación a la situación de últimos días (HR: 2,24; IC95%: 1,69-2,97). Era más probable no morir en casa si se padecía cáncer (HR: 0,76; IC95%: 0,64-0,89), si se detectaba un pobre apoyo externo al grupo familiar (HR: 0,79; IC95%: 0,67-0,93), si el/la paciente no se sentía en paz con los demás (HR: 0,54; IC95%: 0,39-0,75) o si había falta de acuerdo en la planificación del lugar de la muerte (HR: 0,57; IC95%: 0,48-0,68). Conclusiones: La valoración de la complejidad asistencial a través del modelo HexCom-Clin puede contribuir a una mejor planificación anticipada de decisiones al incorporar entre sus dimensiones el sentirse en paz con los demás, el soporte externo al núcleo familiar y el grado de acuerdo sobre el lugar de muerte.

Objective: To examine the associations between the dimensions of the HexCom care complexity model and the place of death. Method: Multicenter longitudinal observational study in patients with advanced illness cared for by home care support teams in Catalonia. Age, gender, type of illness, main caregiver, external support, place of death and the sub-areas of care complexity provided by HexCom were registered. A multivariate Cox regression analysis was performed. Results: Participation of 1527 patients (72% oncology), cared for a median of 35 days. 45% died at home. The probability of dying at home was greater when a greater functional impairment was detected in the initial assessment (hazard ratio [HR]: 7.67; 95% confidence interval [95%CI]: 4.93-11.92), when the patient was male (HR: 1.19; 95%CI: 1.02-1.39), was over 80 years old (HR: 1.41; 95%CI: 1.20-1.66) and when care complexity was detected in relation to being in a situation of last days (HR: 2.24; 95%CI: 1.69-2.97). It was more likely not to die at home in the case of cancer (HR: 0.76; 95%CI: 0.64-0.89), or if poor external support to the family group was detected in the first evaluation (HR: 0.79; 95%CI: 0.67-0.93), or that the patient did not feel at peace with others (HR: 0.56; 95%CI: 0.40-0.79), or lack of agreement on the planning of the place of death (HR: 0.57; 95%CI: 0.48-0.68). Conclusions: The assessment of the complexity of care through the HexCom-Clin model can help to improve advance planning of decisions by incorporating among its dimensions the feeling of peace with others, the external support to the family nucleus and the degree of agreement on the place of death.

Histologic Evaluation of Effect of Three Wavelengths of Diode Laser on Human Gingival Margins.

Introduction: Available evidence suggests that the response of the intervened tissue is directly linked to the effects generated by the cutting instrument used. To determine the histological findings in gingival tissue margins excised through gingivectomies performed using 450 nm, 940 nm, and 980 nm diode lasers. The present study aimed to determine the histological findings in gingival tissue margins excised through gingivectomies performed using 450 nm, 940 nm, and 980 nm diode lasers. Methods: Gingival tissue samples were collected from 30 patients who had undergone gingivectomy procedures. Each study group comprised 10 patients who willingly provided their samples after providing informed consent. The visualization of histological findings was facilitated through Hematoxylin-Eosin staining. Additionally, variables related to pain and hemostasis were assessed during the intraoperative period. Results: The incision quality was categorized as irregular across all three wavelengths. Histological examination of the epithelial tissue revealed the absence of carbonization and the preservation of cell morphology in over 50% of the resection margin in samples obtained with the 450 nm and 940 nm wavelengths. In the connective tissue, observations included carbonization, collagen coagulation, and basophilia, with the 980 nm wavelength demonstrating the highest percentage of samples displaying collagen coagulation in more than 50% of the resection margin. Conversely, the 450 nm wavelength exhibited the highest degree of preservation of the fibroblast structure. Conclusion: Based on a comprehensive analysis of the study results, it can be inferred that the 450nm and 940nm wavelength lasers tend to produce less thermal damage and better cell preservation when compared to the 980nm wavelength.

Adolescents and Young Adults Evaluating a Website for Affective-Sexual Information and Education: A Mixed-Methods Study Protocol.

The website Sexe Joves is a website on sexuality of the Department of Health of the Government of Catalonia (Spain). This study aims to understand the experiences and opinions of people aged 14 to 25 regarding this website, taking into account sex, gender identity, sexual orientation, socioeconomic status and location within Catalonia (urban, semiurban and rural areas). With the objective of improving the website and adpating the resources allocated to it, this study evaluates whether this population is familiar with it and uses it, as well as the website's usability and accessibility (digital equity), usefulness and the relevance of its content. A parallel convergent triangulation design is used: a qualitative study using a social constructivist perspective, and an observational, descriptive and cross-sectional quantitative study. We conduct a discourse analysis of participants and use an "ad hoc" questionnaire to collect quantitative data. A descriptive analysis of all variables is carried out. Affective-sexual education aimed at young people must stem from their participation and the whole range of sexual and gender diversity in order to reach the entire population equally. This analysis will contribute to the design of new strategies for the wesbite Sexe Joves, a public health resource, in order to improve affective-sexual education for young people.

Kinetics of humoral immune response over 17 months of COVID-19 pandemic in a large cohort of healthcare workers in Spain: the ProHEpiC-19 study.

BACKGROUND: Understanding the immune response to the SARS-CoV-2 virus is critical for efficient monitoring and control strategies. The ProHEpic-19 cohort provides a fine-grained description of the kinetics of antibodies after SARS-CoV-2 infection with an exceptional resolution over 17 months. METHODS: We established a cohort of 769 healthcare workers including healthy and infected with SARS-CoV-2 in northern Barcelona to determine the kinetics of the IgM against the nucleocapsid (N) and the IgG against the N and spike (S) of SARS-CoV-2 in infected healthcare workers. The study period was from 5 May 2020 to 11 November 2021.We used non-linear mixed models to investigate the kinetics of IgG and IgM measured at nine time points over 17 months from the date of diagnosis. The model included factors of time, gender, and disease severity (asymptomatic, mild-moderate, severe-critical) to assess their effects and their interactions. FINDINGS: 474 of the 769 participants (61.6%) became infected with SARS-CoV-2. Significant effects of gender and disease severity were found for the levels of all three antibodies. Median IgM(N) levels were already below the positivity threshold in patients with asymptomatic and mild-moderate disease at day 270 after the diagnosis, while IgG(N and S) levels remained positive at least until days 450 and 270, respectively. Kinetic modelling showed a general rise in both IgM(N) and IgG(N) levels up to day 30, followed by a decay with a rate depending on disease severity. IgG(S) levels remained relatively constant from day 15 over time. INTERPRETATION: IgM(N) and IgG(N, S) SARS-CoV-2 antibodies showed a heterogeneous kinetics over the 17 months. Only the IgG(S) showed a stable increase, and the levels and the kinetics of antibodies varied according to disease severity. The kinetics of IgM and IgG observed over a year also varied by clinical spectrum can be very useful for public health policies around vaccination criteria in adult population.

Knowledge, Perceptions, Attitudes and Practices of Midwives Regarding Maternal Influenza and Pertussis Vaccination: A Qualitative Study.

The coverage of maternal vaccination against pertussis and, particularly, influenza is lower than expected. The lack of recommendation from healthcare providers conditions non-vaccination in pregnant women. The purpose was to determine the knowledge, perceptions, attitudes and practices of midwives regarding maternal influenza and pertussis vaccination. A qualitative descriptive study based on semi-structured, face-to-face interviews with seventeen midwives was conducted, including purposive sampling and thematic analyses. Midwives had disparate knowledge and perceptions about the severity of influenza and pertussis in pregnant women, and influenza was not considered very serious. The vaccines were generally considered safe. However, because midwives did not have enough information about the safety of the influenza vaccine, there was a tendency not to recommend it. While most midwives had a positive attitude toward vaccination, their advocation for vaccination against influenza was not as clear as it was for pertussis. Not wanting to influence the decision and assuming an informative-facilitating role also led providers to recommend the influenza vaccine less frequently. Midwives are among the main sources of professional advice for pregnant women. Addressing their understanding and professional practices regarding maternal vaccination is key to change the attitude of pregnant women and thus increase vaccine uptake among them, particularly for influenza.

Validation of a Spanish-language scale for evaluating perceived quality of care of medical abortions before 9 weeks gestation.

BACKGROUND: Spanish Organic Law 2/2010 legalizes abortion within 14 weeks of gestation. Medical abortion with mifepristone and misoprostol is around 97% effective and is offered at primary care centers during the first 9 weeks of gestation. It consists of the administration of 200 mg of mifepristone by a healthcare professional and of the self-administration 800 mg of misoprostol by the patient at home, along with prescribed analgesics. However, the quality of this process as perceived by patients has never been assessed. This study aims to validate a scale designed to assess the perceived quality of the entire process, structure and results of at-home medical abortion. METHODS: Validation study of a Spanish adaptation of the SERVPERF scale. In total, 289 patients completed a self-administered questionnaire consisting of 26 items previously evaluated by a group of experts. A re-test was performed on 53 of these patients 15 days later to assess interobserver consistency. RESULTS: The highest non-response rate for any single item was 2.1%. The floor effect was 26% and the ceiling effect did not surpass 83%. The linearly weighted Kappa coefficient was good to excellent, in general. An exploratory factor analysis was performed with Varimax rotation, obtaining a total of 7 dimensions that explain 65.9% of the variability. The internal consistency (Cronbach's alpha) for all items was 0.862. CONCLUSION: This psychometric instrument is valid and reliable for assessing the quality of care of medical abortion. Medical abortion is efficient, effective and eliminates the need for hospital care, anesthesia and surgical risk. However, user satisfaction has yet to be determined. This study offers a validated scale to assess perceived quality of care, their quality experience and person-centered care for abortion as a fundamental part of overall service quality as a fundamental part of overall service quality.

Parameters Used With Diode Lasers (808-980 nm) in Dentin Hypersensitivity Management: A Systematic Review.

Introduction: The present study aimed to describe parameters used with 808- to 980-nm wavelength diode lasers for managing dentin hypersensitivity and analyze their results. Methods: The inclusion criteria were based on randomized controlled clinical trials using diode lasers at an 808-980 nm wavelength range in patients with dentine hypersensitivity with a minimum of 1-month follow-up. An electronic search for articles on Medline, PubMed and Cochrane databases was performed. The risk of bias was assessed with the Cochrane collaboration tool. Results: Our electronic search resulted in 130 papers, of which 11 articles met the inclusion criteria. A majority of the studies assessed dentine hypersensitivity using the Visual Analogue Scale, which ranged between 2.3 and 8.8 before treatment and significantly reduced to a mean value of 0.45-3.7 after diode laser application. The power settings ranged between 1.5 mW and 3 W with an emission mode of continuous wave, except for 2 authors who used chopped mode. The energy density varied from 2.5 to 128 J/cm2, and the exposure time was between 10 and 120 seconds. The authors applied a minimum of 1 to 4 treatment sessions with a 2-day to 1-week interval between them. Most of the studies mentioned the tooth surface as the treatment site but without describing the specific irradiation points. Conclusion: Despite the heterogeneity of the analyzed variables, a statistically significant improvement in all laser groups was described. However, they cannot be compared homogenously.

Influenza and Pertussis Maternal Vaccination Coverage and Influencing Factors in Spain: A Study Based on Primary Care Records Registry.

The purpose was to determine the coverage of maternal vaccination against influenza and pertussis, and the characteristics associated with being vaccinated, in a health area of Catalonia, Spain. Some 36,032 anonymized and computerized clinical records registries of pregnant women from Primary Care Centres (e-CAP database) were analysed, from between 2015 and 2018. Vaccination coverage and the association with sociodemographic variables and clinical conditions were estimated using a Poisson regression model. Maternal vaccination coverage against influenza ranged between 11.9% in 2015 and 6.8% in 2018, following a decreasing trend (p < 0.001). Coverage with the tetanus toxoid, diphtheria toxoid, and acellular pertussis vaccine varied between 49.8% in 2016 and 79.4% in 2018, following an increasing trend (p < 0.001). Having living children and suffering from obesity were factors associated with not being vaccinated against both infections. The predictive variables of vaccination against influenza were diabetes (IRR: 2.17, 95% CI: 1.42−3.30) and asthma (IRR: 2.05, 95% CI: 1.76−2.38); and for pertussis, it was asthma (IRR: 1.10, 95% CI: 1.03−1.17). Different socio-demographic factors and chronic conditions in pregnant women were associated with maternal vaccination, and which will have to be taken into account in clinical practice when implementing strategies to improve the coverage of the programme.

Photobiomodulation therapy and endodontic treatment of teeth with apical periodontitis using 940-nm diode laser. Report of two cases.

Background: Diode laser (DL) can be used in endodontics both for its bactericidal effect inside the root canal system (RCS) and for photobiomodulation therapy (PBMT) to accelerate the repair of periradicular bone tissue. Clinical Cases: This work presents two cases of pulp necrosis/asymptomatic apical periodontitis (AAP) that were treated with 940-nm DL, administered both to disinfect the root canal and to apply PBMT to the periradicular tissues. The cases were analysed by Cone-Beam Computed Tomography (CBCT). Discussion: DL has become widely accepted due to its high antimicrobial effectiveness and its ability to accelerate the repair of large apical lesions by biostimulation. Nevertheless, differences of opinion persist within the scientific community due to the lack of standardized endodontic protocols. Conclusions: The application of 940-nm DL, both for disinfection of the RCS and for PBMT, is an effective treatment in non-vital teeth with large periapical lesions. In both cases reported, bone neoformation were found at the 6-month check-up. Key words:Low-level laser therapy, photobiomodulation therapy, diode laser, endodontics.
