Poor Self-Rated Sleep Quality and Quantity Associated with Poor Oral Health-Related Quality of Life among Indigenous Australian Adults.

Indigenous Australians score worse on both sleep and oral health. This study aimed to evaluate sleep quality and quantity associated with oral health-related quality of life (OHRQoL) among Indigenous Australian adults. A cross-sectional study involving 728 Indigenous Australian adults aged 18+ years was conducted. Exposure variables were sleep quality and quantity. The primary outcome variable was Oral Health Impact Profile-14 (OHIP14), which has been used to assess OHRQoL. Multivariable log-Poisson regression models were applied to estimate the mean ratios (MRs) for mean OHIP14 scores. The average OHIP14 score was 14.9, and the average amount of sleep was 6.8 h/night. After adjusting for all covariates, self-rated very bad sleep quality was associated with 2.2 times (MR = 2.17, 95% CI: 1.97-2.37) higher OHIP14 scores than those who rated their sleep quality as very good. Participants who self-reported sleeping 7-8 h/night had 0.9 times (MR = 0.89, 95%CI: 0.83-0.95) lower OHIP14 scores than those sleeping more than 8 h. The average number of sleep hours for Indigenous participants were lower than recommended (7-8 h/night). Our findings indicate that poor sleep quality and quantity, and oral health-related behaviours associated with sleep deprivation were positively associated with poor oral health related quality of life among Indigenous Australian adults.

Climate change-related concerns in psychotherapy: therapists’ experiences and views on addressing this topic in therapy

BackgroundWhile adverse impacts of climate change on physical health are well-known, research on its effects on mental health is still scarce. Thus, it is unclear whether potential impacts have already reached treatment practice. Our study aimed to quantify psychotherapists’ experiences with patients reporting climate change-related concerns and their views on dealing with this topic in psychotherapy.MethodsIn a nationwide online survey, responses were collected from 573 psychotherapists from Germany. Therapists reported on the presence of such patients, their socio-demographic characteristics, and climate change-related reactions. Psychotherapists’ views on dealing with this topic in psychotherapy were also assessed. Descriptive statistics were used to analyse the responses.ResultsAbout 72% (410/573) of psychotherapists indicated having had patients expressing concerns about climate change during treatment. Out of these therapists, 41% (166/410) stated that at least one patient sought treatment deliberately because of such concerns. Patients were mainly young adults with higher education. Most frequent primary diagnoses were depression, adjustment disorder, and generalized anxiety disorder. Psychotherapists having encountered such patients differed from those without such encounters in their views on potential functional impairment and the necessity to target the concerns in treatment. Although 79% (326/415) of all respondents felt adequately prepared by their current therapeutic skills, 50% (209/414) reported a lack of information on how to deal with such concerns in therapy.ConclusionsResults indicate that psychotherapists are frequently confronted with climate change-related concerns and regard the mental health impact of climate change on their patients as meaningful to psychotherapeutic care. Regular care could be improved by a continuous refinement of the conceptualization and knowledge of the mental health influences of climate change. This would allow providing tailored methods of assessing and addressing climate change-related concerns in practice.

Assessing the Efficacy of a Campus-Based Transdiagnostic Intervention for Filipino College Students: A Randomized Controlled Trial

ABSTRACT With increasing rates of college students with various mental health concerns, The gap between students’ mental health needs and services available is growing wider. The present study aims to design a campus-based transdiagnostic intervention that can be implemented to address college student mental health. Utilizing a two-arm randomized controlled trial, the results showed that transdiagnostic intervention is effective in lowering psychological distress and transdiagnostic mechanisms (e.g. intolerance of uncertainty, repetitive negative thinking, experiential avoidance, and distress intolerance). The effectiveness of transdiagnostic intervention as a campus-based mental health program in a low-income, Asian country responds to the call for a shift toward alternative low-intensity treatment approaches that can have a greater public mental health impact.

Consolidated guidance for behavioral intervention pilot and feasibility studies

BackgroundIn the behavioral sciences, conducting pilot and/or feasibility studies (PFS) is a key step that provides essential information used to inform the design, conduct, and implementation of a larger-scale trial. There are more than 160 published guidelines, reporting checklists, frameworks, and recommendations related to PFS. All of these publications offer some form of guidance on PFS, but many focus on one or a few topics. This makes it difficult for researchers wanting to gain a broader understanding of all the relevant and important aspects of PFS and requires them to seek out multiple sources of information, which increases the risk of missing key considerations to incorporate into their PFS. The purpose of this study was to develop a consolidated set of considerations for the design, conduct, implementation, and reporting of PFS for interventions conducted in the behavioral sciences.MethodsTo develop this consolidation, we undertook a review of the published guidance on PFS in combination with expert consensus (via a Delphi study) from the authors who wrote such guidance to inform the identified considerations. A total of 161 PFS-related guidelines, checklists, frameworks, and recommendations were identified via a review of recently published behavioral intervention PFS and backward/forward citation tracking of a well-known PFS literature (e.g., CONSORT Ext. for PFS). Authors of all 161 PFS publications were invited to complete a three-round Delphi survey, which was used to guide the creation of a consolidated list of considerations to guide the design, conduct, and reporting of PFS conducted by researchers in the behavioral sciences.ResultsA total of 496 authors were invited to take part in the three-round Delphi survey (round 1, N = 46; round 2, N = 24; round 3, N = 22). A set of twenty considerations, broadly categorized into six themes (intervention design, study design, conduct of trial, implementation of intervention, statistical analysis, and reporting) were generated from a review of the 161 PFS-related publications as well as a synthesis of feedback from the three-round Delphi process. These 20 considerations are presented alongside a supporting narrative for each consideration as well as a crosswalk of all 161 publications aligned with each consideration for further reading.ConclusionWe leveraged expert opinion from researchers who have published PFS-related guidelines, checklists, frameworks, and recommendations on a wide range of topics and distilled this knowledge into a valuable and universal resource for researchers conducting PFS. Researchers may use these considerations alongside the previously published literature to guide decisions about all aspects of PFS, with the hope of creating and disseminating interventions with broad public health impact.

Association between oral health-related quality of life and symptoms of temporomandibular disorder among older adults: A cross-sectional study

ABSTRACT Objective Evaluate the association between oral health-related quality of life (OHRQoL) and self-reported symptoms of TMD. Methods Representative samples of older adults (≥60 years) were included (n = 569). Both TMD symptoms and OHRQoL were assessed by Fonseca Anamnestic Index (FAI) and Oral Health Impact Profile-14 (OHIP-14), respectively. Prevalence (those answering “frequently” or “always” in at least one question), severity (total means scores), and extent (number of questions answered as “frequently” or “always”) of OHRQoL were estimated. Results Overall, 33.4% and 9.5% had mild or moderate/severe TMD symptoms. Those with any symptom of TMD had a prevalence ratio (PR) 38% higher for the worst OHRQoL (95% confidence interval [95%CI]:1.04–1.82) compared to those without TMD symptoms. Worst OHRQoL were observed for those with mild (PR:1.35; 95%CI:1.01–1.81) and moderate/severe TMD (PR:1.53; 95%CI:1.04–2.26). Similar results were detected in the severity and extent of OHRQoL. Conclusion Severity TMD was associated with worse ORHQoL.

Validation of collection and anaerobic fermentation techniques for measuring prebiotic impact on gut microbiota

BackgroundDefining the ability of prebiotic dietary carbohydrates to influence the composition and metabolism of the gut microbiota is central to defining their health impact in diverse individuals. Many clinical trials are using indirect methods. This study aimed to validate collection and fermentation methods enabling their use in the context of clinical studies. Methods and ResultsParameters tested included stool sample acquisition, storage, and growth conditions. Stool from 3 infants and 3 adults was collected and stored under varying conditions. Samples were cultured anaerobically for two days in the presence of prebiotics, whereupon optical density and pH were measured across time. Whole genome shotgun sequencing and NMR metabolomics were performed. Neither the type of collection vial (standard vial and two different BD anaerobic collection vials) nor cryopreservation (-80 °C or 4 °C) significantly influenced either microbial composition at 16 h of anaerobic culture or the principal components of the metabolome at 8 or 16 h. Metagenomic differences were driven primarily by subject, while metabolomic differences were driven by fermentation sugar (2’-fucosyllactose or dextrose). ConclusionsThese data identified a feasible and valid approach for prebiotic fermentation analysis of individual samples in large clinical studies: collection of stool microbiota using standard vials; cryopreservation prior to testing; and collecting fermentation read-out at 8 and 16 hr. Thus, fermentation analysis can be a valid technique for testing the effects of prebiotics on human fecal microbiota.

The impact of health insurance on maternal and reproductive health service utilization and financial protection in low- and lower middle-income countries: a systematic review of the evidence

BackgroundLow- and middle-income countries have committed to achieving universal health coverage (UHC) as a means to enhance access to services and improve financial protection. One of the key health financing reforms to achieve UHC is the introduction or expansion of health insurance to enhance access to basic health services, including maternal and reproductive health care. However, there is a paucity of evidence of the extent to which these reforms have had impact on the main policy objectives of enhancing service utilization and financial protection. The aim of this systematic review is to assess the existing evidence on the causal impact of health insurance on maternal and reproductive health service utilization and financial protection in low- and lower middle-income countries.MethodsThe review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search included six databases: Medline, Embase, Web of Science, Cochrane, CINAHL, and Scopus as of 23rd May 2023. The keywords included health insurance, impact, utilisation, financial protection, and maternal and reproductive health. The search was followed by independent title and abstract screening and full text review by two reviewers using the Covidence software. Studies published in English since 2010, which reported on the impact of health insurance on maternal and reproductive health utilisation and or financial protection were included in the review. The ROBINS-I tool was used to assess the quality of the included studies.ResultsA total of 17 studies fulfilled the inclusion criteria. The majority of the studies (82.4%, n = 14) were nationally representative. Most studies found that health insurance had a significant positive impact on having at least four antenatal care (ANC) visits, delivery at a health facility and having a delivery assisted by a skilled attendant with average treatment effects ranging from 0.02 to 0.11, 0.03 to 0.34 and 0.03 to 0.23 respectively. There was no evidence that health insurance had increased postnatal care, access to contraception and financial protection for maternal and reproductive health services. Various maternal and reproductive health indicators were reported in studies. ANC had the greatest number of reported indicators (n = 10), followed by financial protection (n = 6), postnatal care (n = 5), and delivery care (n = 4). The overall quality of the evidence was moderate based on the risk of bias assessment.ConclusionThe introduction or expansion of various types of health insurance can be a useful intervention to improve ANC (receiving at least four ANC visits) and delivery care (delivery at health facility and delivery assisted by skilled birth attendant) service utilization in low- and lower-middle-income countries. Implementation of health insurance could enable countries’ progress towards UHC and reduce maternal mortality. However, more research using rigorous impact evaluation methods is needed to investigate the causal impact of health insurance coverage on postnatal care utilization, contraceptive use and financial protection both in the general population and by socioeconomic status.Trial registrationThis study was registered with Prospero (CRD42021285776).

Ghanaian women’s experience of intimate partner violence (IPV) during group antenatal care: a brief report from a cluster randomised controlled trial

ABSTRACT Intimate partner violence (IPV) impacts women of reproductive age globally and can lead to significant negative consequences during pregnancy. This study describes an exploratory aim of a cluster randomised controlled trial designed to assess the outcomes of Group Antenatal Care (ANC) in Ghana. The purpose was to understand the effect of a healthy relationship Group ANC module on experiences of IPV and safety planning as well as to explore the relationship between self-efficacy on the experiences of IPV and safety planning. Data were collected at baseline and at 11–14 months postpartum (post). Survey measures captured reported experiences of violence, self-efficacy, and safety. The chi-square test was used to compare baseline and post scores, and a logistic regression was performed to ascertain the effects of self-efficacy on the experiences of IPV in both groups. The sample included 1,751 participants, of whom 27.9% reported IPV at baseline. Between baseline and postpartum, there was a small increase in reported emotional (6.2% vs. 4.6%) and sexual (5.4% vs. 3.2%) violence in the intervention group compared to the control group. Logistic regression demonstrated that an increasing self-efficacy score was associated with an increased likelihood of experiencing IPV. There were no changes in safety knowledge. This study found higher rates of reported sexual and emotional violence post-intervention among the intervention group. Group ANC may be just one part of a portfolio of interventions needed to address IPV at all socio-ecological levels. Paper Context Main findings: There was no reduction in experiences of intimate partner violence or increases in safety planning among Ghanaian pregnant women participating in a Group Antenatal Care session focused on healthy relationships and safety planning. Added knowledge: Group Antenatal Care has been identified as an effective modality for providing antenatal care and facilitating conversations about sensitive topics such as intimate partner violence and safety. However, this study highlights the importance of developing multifaceted approaches to decrease the risk of intimate partner violence among women, especially during the critical times of pregnancy and postpartum. Global health impact for policy and action: Effective global health action and policy must extend beyond educational efforts, incorporating multifaceted strategies that include healthcare provider training, robust community engagement, and legislation aimed at preventing intimate partner violence, with a special focus on safeguarding the well-being of women during pregnancy and the postpartum period.

Impact of treament with orthodontic aligners on the oral health-related quality of life

BackgroundThere is an increasing interest in information on the effects of orthodontic aligners on the oral health-related quality of life (OHRQoL) of people.AimTo compare the impact of orthodontic aligners versus conventional fixed appliances on OHRQoL, using a validated tool and controlling for sociodemographic and clinical variables.MethodSixty-one individuals participated in this study. Group 1 (G1) consisted of 33 individuals under treatment with orthodontic aligners and Group 2 (G2) comprised 28 individuals under treatment with conventional fixed appliances. OHRQoL was evaluated with the Oral Health Impact Profile (OHIP-14) in which 14 items are distributed across seven dimensions: functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. The higher the score, the more negative is the perception of the individual regarding his/her OHRQoL. Descriptive statistics, Mann-Whitney test, and Poisson regression were performed. Effect Size (ES) and Minimal Clinically Important Difference (MCID) were also determined.ResultsParticipants’ mean age was 30.69 years. Individuals in G1 had a significantly lower score for physical pain and the total score of OHIP-14 compared to individuals in G2 (p < 0.05). The ES was large (ES = 0.74) for physical pain and moderate (ES = 0.46) for the total score. The ES was moderate for physical disability (ES = 0.50). The difference between groups for physical pain (1.30) and for physical disability (0.90) was greater than the MCID (0.87 and 0.88, respectively). Poisson regression showed that G2 individuals showed a score for physical pain 1.39 times higher than those of G1 in the adjusted model (OR = 1.39, [1.03–1.89], p = 0.031).ConclusionThose under treatment with orthodontic aligners have a more positive perception of OHRQoL compared to those wearing fixed appliances.

Responsiveness and sensitivity of PROMs to change in disease activity status in early and established rheumatoid arthritis.

To determine whether patient reported outcome measures (PROMs) capturing activity limitations, health impact, pain, fatigue and work ability are responsive and sensitive to changes in disease activity status in patients with early and established rheumatoid arthritis (RA). All early RA patients (n = 557) from the tREACH-trial and established RA patients (n = 188) from the TARA-trial were included. Both studies were multicentre, single-blinded trials with a treat-to-target management approach. The following PROMs were studied: Health Assessment Questionnaire Disability Index(HAQ-DI), morning stiffness severity, EQ-5D, general health, 36-item short form(SF-36), joint pain, fatigue and productivity loss. Mean changes in PROMs between two consecutive visits were compared with changes in disease activity status(remission, low disease activity and active disease) using linear mixed models and standardised response means. Additionally, the proportion of individual observations that showed an expected PROM response to disease activity status alterations was calculated. HAQ-DI, morning stiffness severity, general health, EQ-5D and joint pain demonstrated responsiveness to improvement or worsening of disease activity status in both early and established RA. SF-36 physical and mental component scale, fatigue and productivity loss did not show this effect in both groups. Across nearly all PROMs, the magnitude of change and the proportion of individual observations that reflect a shift from and to active disease remained low. HAQ-DI, morning stiffness severity, EQ-5D, general health and joint pain are responsive to disease activity status alterations on a group level in both early and established RA. For the individual patient the responsiveness of these PROMs is poor. tREACH trial (www.isrctn.com, ISRCTN26791028) and TARA trial (www.onderzoekmetmensen.nl, NTR2754).

Self-perceived oral health and orofacial aesthetics of cleft patients.

To evaluate the self-perceived oral health and aesthetics of the dentition and jaw in patients with different types of oral cleft, measured by patient-reported outcome measures (PROMs). Additionally, to compare the results of the PROMs between cleft lip and or/palate (CL/P) patients and non-affected controls. 420 CL/P patients treated at the cleft team of the Erasmus Medical Center, Rotterdam, The Netherlands, were included, and 138 non-cleft patients were recruited as control-group. Patient's perceptions were retrospectively evaluated using the CLEFT-Q Teeth for dental aesthetics at ages 8, 12 and 22, CLEFT-Q Jaw for jaw aesthetics at ages 12 and 22, and the Child Oral Health Impact Profile-Oral Symptoms Subscale (COHIP-OSS) for oral health at ages 8 and 12. One-way ANOVA was used to compare differences in oral health and aesthetic perceptions among age-groups, cleft types, as well as between cases and controls. CL/P patients were significantly less satisfied than controls with their dental aesthetics (p = 0.001). CL/P patients reported significantly lower satisfaction on CLEFT-Q Teeth scores at ages 8 and 12, than at 22years (p < 0.001). Patients with the most extensive cleft phenotype, Cleft Lip and Palate (CLAP), reported lowest satisfaction on the CLEFT-Q Teeth. No differences in perceptions of oral health nor in aesthetics of the jaw were found in the different cleft types, ages, nor in study versus control group. This study found differences in self-perceived dental aesthetics: CL/P patients are less satisfied than non-affected controls. CLAP patients are least satisfied, but satisfaction increases with age.

Sex steroid levels in women with hypopituitarism: A case-controlled observational study.

Women with hypopituitarism remain at increased risk of morbidity and mortality. Insufficient replacement of sex steroids has been suggested as a contributing factor, but sex steroid levels in women with hypopituitarism have not been comprehensively mapped. To quantify sex steroids in women with hypopituitarism by a high-sensitivity assay. Using a combination of clinical and biochemical criteria, women with hypopituitarism (n = 104) who started growth hormone replacement 1995-2014 at a single center were categorized as eugonadal or having hypogonadotropic hypogonadism (HH). A population-based cohort of women (n = 288) served as controls. Eugonadal women and controls were categorized as pre-/postmenopausal and HH women as younger/older (≤ or >52 years). Dehydroepiandrosterone (DHEA), androstenedione, testosterone, dihydrotestosterone, progesterone, 17αOH-progesterone, estradiol and estrone were analyzed by a validated liquid chromatography-tandem mass spectrometry assay. Among both premenopausal/younger and postmenopausal/older women, women with HH had lower levels of sex steroid precursors (DHEA, androstenedione) and androgens (testosterone and dihydrotestosterone) than controls. Progesterone, 17αOH-progesterone, estrone and estradiol showed similar patterns. Women with HH and adrenocorticotropic hormone (ACTH) deficiency had markedly lower concentrations of all sex hormones than those without ACTH deficiency. This study demonstrates for the first time a broad and severe sex steroid deficiency in both younger and older women with HH, particularly in those with combined gonadotropin and ACTH deficiency. The health impact of low sex steroid levels in women with hypopituitarism requires further study and women with combined gonadotropin and ACTH deficiency should be a prioritized group for intervention studies with sex hormone replacement.

The role of income inequality as an ecological determinant of mental health: A nation-wide multilevel analysis on an Italian sample.

Income inequality, a pivotal determinant of general and mental health, operates through intricate mechanisms at various geographical scales. While established at country or region levels, the impact of lower-level (municipal or neighborhood) inequality remains inconsistent. This study explores the influence of regional- and municipal-level income inequality on individual psychological distress during the COVID-19 pandemic in Italy, employing a multilevel data analysis. In a post hoc analysis of data from the first wave of the pandemic (March to April 2020), three hierarchical levels were considered: individual participants, municipalities, and regions. Depressive and anxiety symptoms were measured using the PHQ-9 and GAD-7 scales, while the Gini coefficient gauged income inequality at municipal and regional levels. The analysis incorporated demographic variables as potential confounders. The study encompassed 21 regions, 3,900 municipalities, and 21,477 subjects. Income inequality at both regional and municipal levels exhibited associations with distress scores, suggesting independent effects. Notably, higher distress scores were identified in southern regions with elevated inequality, despite a more substantial COVID-19 impact in the north. Findings contribute to existing literature by emphasizing the independent impact of lower-level (municipal) and higher-level (regional) income inequality on population psychopathology. The study supports theories suggesting diverse pathways through which inequality at different levels influences health, such as potential associations with healthcare system dysfunction at the regional level and welfare dysfunction at the municipal level. The observed north-south gradient in distress scores highlights the need for psychosocial interventions to alleviate income inequality, especially in historically disadvantaged southern regions. Future research should explore the nuanced interplay between income inequality and various ecological variables to provide a comprehensive understanding of its health impact.

Health impact and cost-effectiveness of expanding routine immunization coverage in India through Intensified Mission Indradhanush.

Many children do not receive a full schedule of childhood vaccines, yet there is limited evidence on the cost-effectiveness of strategies for improving vaccination coverage. Evidence is even scarcer on the cost-effectiveness of strategies for reaching "zero-dose children," who have not received any routine vaccines. We evaluated the cost-effectiveness of periodic intensification of routine immunization (PIRI), a widely applied strategy for increasing vaccination coverage. We focused on Intensified Mission Indradhanush (IMI), a large-scale PIRI intervention implemented in India in 2017-2018. In 40 sampled districts, we measured the incremental economic cost of IMI using primary data, and used controlled interrupted time-series regression to estimate incremental vaccination doses delivered. We estimated deaths and disability-adjusted life years (DALYs) averted using the Lives Saved Tool and reported cost-effectiveness from immunization program and societal perspectives. We found that, in sampled districts, IMI had an estimated incremental cost of 2021US$13.7 (95% uncertainty interval: 10.6 to 17.4) million from an immunization program perspective and increased vaccine delivery by an estimated 2.2 (-0.5 to 4.8) million doses over a 12-month period, averting an estimated 1,413 (-350 to 3,129) deaths. The incremental cost from a program perspective was $6.21 per dose ($2.80 to dominated), $82.99 per zero-dose child reached ($39.85 to dominated), $327.63 ($147.65 to dominated) per DALY averted, $360.72 ($162.56 to dominated) per life-year saved, and $9,701.35 ($4,372.01 to dominated) per under-five death averted. At a cost-effectiveness threshold of 1x per-capita GDP per DALY averted, IMI was estimated to be cost-effective with 90% probability. This evidence suggests IMI was both impactful and cost-effective for improving vaccination coverage, though there is a high degree of uncertainty in the results. As vaccination programs expand coverage, unit costs may increase due to the higher costs of reaching currently unvaccinated children.

Biological wastewater treatment: a comprehensive sustainability analysis using life cycle assessment.

The research conducts a life cycle assessment (LCA) on wastewater treatment (WWT) methods-membrane bioreactor (MBR), soil biotechnology (SBT), and bio-electrochemical constructed wetlands (BCW)-in comparison with the conventional activated sludge process (ASP). Employing SimaPro v9.5 with a cradle-to-gate system boundary, the analysis utilizes the IMPACT 2002 + method, employing per cubic meter of treated wastewater as the functional unit. The analysis shows that SBT exhibits the lowest environmental impacts among the considered WWT methods. The global warming potential was 0.0996 kg CO2 eq. for SBT, 1.33 kg CO2 eq. for MBR, 0.131 kg CO2 eq. for BCW, and 0.544 kg CO2 eq. for ASP. BCW demonstrates a 75.91% decrease, while MBR exhibits a 144.48% increase compared to ASP. Notably, electricity consumption emerges as the primary contributor to environmental impact in MBR and ASP. The resource impact category varies with a 138.15% increase in MBR and an 83.41% decrease in SBT compared to ASP. Additionally, the research indicates that the high human health impact observed in MBR results mainly from increased carcinogens (0.00176 kg C2H3Cl eq.), non-carcinogens (0.01 kg C2H3Cl eq.), and ionizing radiation (3.34 Bq C-14 eq.). The findings underscore the importance of considering treatment efficiency and broader environmental implications in selecting WWT methods. As the world emphasizes sustainability, such LCA studies provide valuable insights for making informed decisions in wastewater management.

Long-term results of aesthetic and functional restoration of frontal teeth in young people with preserved systemic and dental health

AIM. To analyze the stability of the results of aesthetic and functional restoration of frontal teeth in young people with preserved systemic and dental health based on expert assessments and subjective conclusions of the patient.MATERIALS AND METHODS. The quality preservation of 63 composite restorations of frontal teeth performed a year ago in 54 patients aged 19–27 years with preserved systemic and dental health was analyzed by experts using the Ryge international assessment system. The calculation of integral and scale indicators of the dental index “Oral Health Impact Profile” OHIP-14-aesthetic-RU supplemented the selfassessment of the quality of previously performed dental restoration treatment in the smile area.RESULTS. In 12 months after the restoration treatment most composite restorations corresponded to high aesthetic and functional characteristics in terms of the quality of preservation of the restored anatomical shape (respectively 70.0–61.5%), texture and color of the surface (66.7–65.4%) and edge fit (66.7–65.4%). The largest number of unacceptable assessments of the quality of restoration of III-IV classes were obtained according to the criteria of “Edge fit” (6.7% and 15.4%, respectively) and “Surface quality” (6.7%). The absolute majority (96.4%) of patients are satisfied with the quality of previously performed restoration and their preservation, which was confirmed by both professional opinions of dental experts and indicators of the aesthetically oriented dental quality of life index OHIP-14-aesthetic RU (the integral indicator was 5.92 ± 1.31 points), comparable with the index values in healthy young people with an intact dentition.CONCLUSIONS. The use of modern light-curing composite materials for the treatment of carious defects of anterior teeth makes it possible to achieve high aesthetic and functional results of restoration according to its comprehensive (objective / subjective) assessment in the long-term follow-up.

Estimating the Potential Public Health Value of BCG Revaccination.

An upcoming trial may provide further evidence that adolescent/adult-targeted BCG revaccination prevents sustained Mycobacterium tuberculosis infection, but its public health value depends on its impact on overall tuberculosis morbidity and mortality, which will remain unknown. Using previously calibrated models for India and South Africa, we simulated BCG revaccination assuming 45% prevention-of-infection efficacy, and we evaluated scenarios varying additional prevention-of-disease efficacy between +50% (reducing risk) and -50% (increasing risk). Given the assumed prevention-of-infection efficacy and range in prevention-of-disease efficacy, BCG revaccination may have a positive health impact and be cost-effective. This may be useful when considering future evaluations and implementation of adolescent/adult BCG revaccination.

Environmental exposure to multiple chemical elements in Peruvian populations: a review of selected studies

Background Population-based exposure assessments for heavy metals and metalloids (by governmental and private institutions) are common in Peru, but most studies generally focus on the analysis of a single chemical element, like lead or mercury, and lack an appropriate reference regarding the health impact on the exposed population. The complex/mixed chemical interactions within the human body have not yet been studied for all long-term health effects. Methods We reviewed laboratory results from five studies, between 2005-2013, that analysed multiple elements (between 13 and 17 chemical elements in each study) in spot urine samples from Peruvian communities considered exposed and not exposed. All laboratory analysis were performed using inductively coupled plasma mass spectrometry (ICP-MS) at the Environmental Health Laboratory Division of the Centers for Disease Control and Prevention (CDC) of the United States. Results Six chemical elements (total arsenic, caesium, cobalt, lead, molybdenum, and thallium) were present in almost all spot urine samples (&gt;98% of participants), evidencing exposure (qualitative assessment). Exposure to other chemical elements like barium, cadmium, tungsten, antimony and uranium, varied among localities, while chemical elements like beryllium and platinum were rarely detected (&lt;3% and &lt;10% of participants, respectively) in spot urine samples. Most geometric means of urine concentration for total arsenic, lead, cadmium and mercury are higher for the Peruvian locations than for national estimates in Canada and the United States, but not in all locations. Conclusion Comparing averages across different populations can be misleading but comparing periodic values from the same population in the future could evidence an exposure trend. Future studies are needed to develop reference levels for exposed Peruvian populations. This study highlights potential health risks from exposure to environmental chemical elements and can be the first step towards understanding and mitigating human exposure to heavy metals and metalloids for known exposed populations in Peru.

Association between the COVID-19 pandemic and mental health in very old people in Sweden.

During the COVID-19 pandemic, Sweden implemented social distancing measures to reduce infection rates. However, the recommendation meant to protect individuals particularly at risk may have had negative consequences. The aim of this study was to investigate the impact of the COVID-19 pandemic on very old Swedish peoples' mental health and factors associated with a decline in mental health. We conducted a cross-sectional study among previous participants of the SilverMONICA (MONItoring of Trends and Determinants of CArdiovascular disease) study. Of 394 eligible participants, 257 (65.2%) agreed to participate. Of these, 250 individuals reported mental health impact from COVID-19. Structured telephone interviews were carried out during the spring of 2021. Data were analysed using the χ2 test, t-test, and binary logistic regression. Of 250 individuals (mean age: 85.5 ± 3.3 years, 54.0% women), 75 (30.0%) reported a negative impact on mental health, while 175 (70.0%) reported either a positive impact (n = 4) or no impact at all (n = 171). In the binary logistic regression model, factors associated with a decline in mental health included loneliness (odds ratio [95% confidence interval]) (3.87 [1.83-8.17]) and difficulty adhering to social distancing recommendations (5.10 [1.92-13.53]). High morale was associated with positive or no impact on mental health (0.37 [0.17-0.82]). A high percentage of very old people reported a negative impact on mental health from the COVID-19 pandemic, primarily from loneliness and difficulty adhering to social distancing measures, while high morale seemed to be a protective factor.

Maxillary sinus floor augmentation with autogenous bone graft compared with composite grafts: A one-year single-blinded randomized controlled trial.

The objective was to assess the one year implant treatment outcome and patient-related outcome measures (PROMs) following maxillary sinus floor augmentation (MSFA) with autogenous bone graft (ABG) from the zygomatic buttress (control) compared with 1:1 mixture of ABG and anorganic porcine bone mineral (APBM) (Test I) or biphasic bone graft material (BBGM) (Test II). Sixty healthy patients (34 females, 26 males) were randomly allocated to either control or test groups. Outcome measures included survival of suprastructures and implants, implant stability quotient, health status of peri-implant tissue, peri-implant marginal bone loss, frequency of complications, and PROMs using Oral Health Impact Profile-14 combined with questionnaire assessing patient perception of peri-implant soft tissue, prosthetic solution, implant function, and implant treatment outcome using visual analogue scale. Mean differences were expressed with standard deviation and 95% confidence interval. Level of significance was .05. All suprastructures and implants were well-functioning after one year of functional implant loading. There was no significant difference between control and test groups in any of the applied outcome measures. The implant stability significantly increased from implant placement to abutment connection within all groups (p < .001). High patient satisfaction and significant improvement in oral health-related quality of life was also reported within all groups. This study demonstrates that MSFA with composite grafts containing minimal amounts of ABG reveals comparable implant treatment outcomes as compared with ABG alone, after one year of functional implant loading. Extensive ABG harvesting in conjunction with MSFA therefore seems not to be needed.
