ABSTRACT

BACKGROUND: Although it is known that the soft tissues around dental implants have an impact on its health and cause marginal bone loss, it is still uncertain exactly how. The aim of the study is to evaluate the effect of vertical mucosal thickness and keratinized mucosal width on marginal bone loss and periodontal clinical parameters in the 2-year follow-up of implants placed at the bone level.

MATERIAL AND METHODS: 87 bone-level dental implants were placed in 31 patients. The initial vertical mucosal thickness (VMT) was recorded at implant placement. At the second year follow-up, gingival index (GI), plaque index (PI), probing depth (PD), bleeding on probe (BOP), radiographic marginal bone loss (MBL) and width of the keratinized mucosa (KMW) were all measured. MBL and periodontal clinical parameters were evaluated separately according to VMT and KMW. VMT was categorized into two groups, Group 1 (≤ 2mm) and Group 2 (> 2 mm). KMW was divided into two groups, Group A (< 2mm) and Group B (≥ 2 mm).

RESULTS: Dental implants had a mean MBL of 0.39 ± 0.57 mm in the 2-year follow-up. MBL in Group 1 and 2 was 0.39 ± 0.42 mm and 0.38 ± 0.65 mm, respectively. MBL in Group A and B was 0.41 ± 0.68 mm and 0.37 ± 0.49 mm, respectively. No significant difference in MBL was found in the KMW and VMT groups (p>0.05). The group with the thicker vertical mucosa was shown to have statistically substantially higher PI and GI values (p=0.040 and p=0.014, respectively).

CONCLUSIONS: Within the limits of the present study, it was observed that the vertical mucosal thickness and the width of the keratinized mucosa did not affect the marginal bone loss. In addition, it was observed that the insufficiency of the width of the keratinized mucosa did not affect the periodontal clinical parameters, but the thicker vertical mucosa could increase the plaque index and gingival index.

ABSTRACT

Hybridization is recognized as an important evolutionary force, but identifying and timing admixture events between divergent lineages remains a major aim of evolutionary biology. While this has traditionally been done using inferential tools on contemporary genomes, the latest advances in paleogenomics have provided a growing wealth of temporally distributed genomic data. Here, we used individual-based simulations to generate chromosome-level genomic data for a two-population system and described temporal neutral introgression patterns under a single- and two-pulse admixture model. We computed six summary statistics aiming to inform the timing and number of admixture pulses between interbreeding entities: lengths of introgressed sequences and their variance within-genomes, as well as genome-wide introgression proportions and related measures. The first two statistics could confidently be used to infer inter-lineage hybridization history, peaking at the beginning and shortly after an admixture pulse. Temporal variation in introgression proportions and related statistics provided more limited insights, particularly when considering their application to ancient genomes still scant in number. Lastly, we computed these statistics on Homo sapiens paleogenomes and successfully inferred the hybridization pulse from Neanderthal that occurred approximately 40 to 60 kya. The scarce number of genomes dating from this period prevented more precise inferences, but the accumulation of paleogenomic data opens promising perspectives as our approach only requires a limited number of ancient genomes.

ABSTRACT

BACKGROUND: This study aims at investigating the mediating role of rumination and COVID-19 burnout in the relationship among depression, resilience and intolerance of uncertainty.

SUBJECTS AND METHODS: This is a correlational study. The study sample is composed of 436 (F=259, M=177) Turkish university students recruited via convenience sampling method. The participants responded to the Depression Scale, COVID-19 Burnout Scale, Rumination Scale, Resilience Scale and Intolerance of Uncertainty Scale face to face. The model that was developed within the scope of the current study was tested via path analysis, which is a technique of Structural Equation Modelling (SEM).

RESULTS: The study findings show that resilience and intolerance of uncertainty predict depression and rumination at a statistically significant level. Moreover, rumination directly predicts COVID-19 burnout, while COVID-19 burnout predicts depression. On the other hand, indirect effect modelling shows that resilience predicts depression with the mediating effect of rumination and COVID-19 burnout at a statistically significant level. Lastly, intolerance of uncertainty predicts depression with the mediating effect of rumination and COVID-19 burnout at a statistically significant level.

CONCLUSION: The current findings suggest that an increase in the level of intolerance of uncertainty and a decrease in the level of resilience increase rumination, which in turn increases depression by increasing COVID-19 burnout.

ABSTRACT

BACKGROUND: Non-attendance to outpatient mental health appointments is associated with adverse clinical and financial outcomes. The aim of this study was to investigate the rates of non-attendance to outpatient Consultation-Liaison Psychiatry (CLP) appointments and the factors associated with non-attendance.

SUBJECTS AND METHODS: Retrospective cohort study, including two groups of data: 950 initial and 3503 follow-up appointments between 01/01/2015 and 31/12/2019. We employed descriptive statistics, parametric/non-parametric tests and logistic regression analysis. We used a range of environmental, socio-demographic and service-related characteristics as independent parameters and non-attendance as the dependent parameter.

RESULTS: Initial and follow-up non-attendance rates were 27.5% and 18.8% respectively. Opting-out text message reminders was associated with both initial and follow-up non-attendance. Higher education was associated with initial non-attendance, whereas lower education with follow-up non-attendance. Other factors associated with non-attendance to initial appointments were: English being the participant’s primary communication language, having an appointment with a psychiatrist as opposed to a trained nurse or Cognitive Behavioural Therapist, and longer waiting time. Follow-up non-attendance was also associated with younger age, shorter driving distance and higher income/employment.

CONCLUSION: We suggest that improving opt-in rates through a combination of staff and patient education and promotion, improving waiting lists, reducing the stigma associated with seeing a psychiatrist, but also perhaps targeting different socio-economic groups of patients with different strategies should be the focus of policy making to tackle non-attendance. Further research into patient-related and environmental factors, such as day of the week, driving distance, language of primary communication, education, income and employment is warranted in order to design more effective policies and improve engagement with CLP, but also psychiatric services in general.

ABSTRACT

BACKGROUND: Misattribution of motivational salience to non-salient (neutral) stimuli could be viewed as a hallmark of psychosis in schizophrenia. Studies have recently revealed increased subjective experience of emotional arousal (EA) to neutral social stimuli in paranoid schizophrenia psychosis, suggesting a misattribution of emotional salience to them. We examined this phenomenon directly by quantifying the level of EA subjectively attributed to low-arousal, neutral-valenced faces.

SUBJECTS AND METHODS: Patients with remitted schizophrenia (PG) (n=26), first-degree relatives of schizophrenic patients (RG) (n=25), and healthy controls (HCG) (n=36) were compared in terms of oxidative stress parameters -serum Superoxide Dismutase, Catalase, Glutathione Peroxidase (GPx), Nitrite, Nitrate, Malondialdehyde, and Total Glutathione levels-, social cognition measured by the Reading the Mind in the Eyes Test and working memory measured by the N-back Task. Groups were compared, assuming that HCG had a genetically lower risk of schizophrenia compared to PG and RG.

RESULTS: HCG performed significantly better than PG and RG, who were genetically at high risk, in terms of social cognition (respectively p=0.000, p=0.014), working memory (respectively p=0.001, p=0.003), and had statistically lower Glutathione Peroxidase (GPX) level than the PG and RG (both p:0.000). After controlling for the effect of the general intellectual abilities measured by the Raven Standard Progressive Matrices Test and working memory the differences between groups on the Eyes Test disappeared (p=0.057). However, this value tended to be significant.

CONCLUSION: It was concluded that social cognition and working memory and GPx level may be used as endophenotypes and social cognition, working memory, and general intellectual skills are different but strongly related constructs. Endophenotypes guide treatment targets even after the disease has developed. The results of our study showed that in addition to psychopharmacological treatments, interventions to reduce oxidative stress and approaches to improve cognitive skills will have a positive impact on the disease’s progression.

ABSTRACT

BACKGROUND: Early marriage is defined as the union of one or both partners before reaching the age of 18 for the first time. This practice is widely prevalent in underdeveloped countries, particularly in Ethiopia, and has been observed to have detrimental effects on the educational and personal development of both male and female individuals.

METHODS: The present study conducted a comprehensive search of the Science Direct, Scopus, Google Scholar, EMBASE, and PubMed databases. The data were extracted using Microsoft Excel (version 14) and analyzed using STATA statistical software. To examine publication bias, a forest plot, rank test, and Egger’s regression test were utilized. Heterogeneity was assessed by calculating I2 and conducting an overall estimated analysis. Additionally, subgroup analysis was performed based on the study region and sample size. The pooled odds ratio was calculated.

RESULTS: Out of a total of 654 articles, 14 papers with 67,040 research participants were included in this analysis. The pooled prevalence of early marriage among women in Ethiopia was 56.34% (95% CI: 51.34-61.34), I2 = 78.3%). The Amhara region exhibited the highest prevalence of early marriage, with a rate of 59.01%, whereas the Oromia region demonstrated the lowest incidence, with a prevalence rate of 53.88%. The prevalence of early marriage was found to be 58.1% for a sample size exceeding 1000, and 50.9% for a sample size below 1000. No formal education (AOR = 5.49; 95%CI: 2.99, 10.07), primary education (AOR = 3.65; 95%CI: 2.11, 6.32), secondary education (AOR = 2.49; 95%CI: 1.60, 3.87), rural residency (AOR = 4.52; 95%CI: 1.90, 10.74) and decision made by parents (AOR = 2.44; 95%CI: 1.36, 4.39) were associated factors.

CONCLUSION AND RECOMMENDATION: In Ethiopia, there was a high rate of early marriage among women. The research findings indicate that early marriage is more prevalent among mothers who possess lower levels of educational attainment, reside in rural areas, and are subject to parental decision-making. Our stance is firmly in favor of expanding the availability of maternal education and promoting urban residency. Furthermore, the promotion of autonomous decision-making by clients regarding their marital affairs is of paramount importance to family leaders.

ABSTRACT

INTRODUCTION: The lack of standardized methods for detecting biofilms continues to pose a challenge to microbiological diagnostics since biofilm-mediated infections induce persistent and recurrent infections in humans that often defy treatment with common antibiotics. This study aimed to evaluate diagnostic parameters of four in vitro phenotypic biofilm detection assays in relation to antimicrobial resistance in aerobic clinical bacterial isolates.

METHODS: In this cross-sectional study, bacterial strains from clinical samples were isolated and identified following the standard microbiological guidelines. The antibiotic resistance profile was assessed through the Kirby-Bauer disc diffusion method. Biofilm formation was detected by gold standard tissue culture plate method (TCPM), tube method (TM), Congo red agar (CRA), and modified Congo red agar (MCRA). Statistical analyses were performed using SPSS version 17.0, with a significant association considered at p<0.05.

RESULT: Among the total isolates (n = 226), TCPM detected 140 (61.95%) biofilm producers, with CoNS (9/9) (p<0.001) as the predominant biofilm former. When compared to TCPM, TM (n = 119) (p<0.001) showed 90.8% sensitivity and 70.1% specificity, CRA (n = 88) (p = 0.123) showed 68.2% sensitivity and 42% specificity, and MCRA (n = 86) (p = 0.442) showed 65.1% sensitivity and 40% specificity. Juxtaposed to CRA, colonies formed on MCRA developed more intense black pigmentation from 24 to 96 hours. There were 77 multi-drug-resistant (MDR)-biofilm formers and 39 extensively drug-resistant (XDR)-biofilm formers, with 100% resistance to ampicillin and ceftazidime, respectively.

CONCLUSION: It is suggested that TM be used for biofilm detection, after TCPM. Unlike MCRA, black pigmentation in colonies formed on CRA declined with time. MDR- and XDR-biofilm formers were frequent among the clinical isolates.

ABSTRACT

BACKGROUND: Among gay, bisexual, and other men who have sex with men (GBM), sexual orientation disclosure to social groups can act as a significant risk for depression. The primary goal of this research is to understand the association between disclosure and depression, the association of social support and intimate partner violence (IPV) experiences, depression, and disclosure.

METHODS: This project uses a secondary dataset of Thailand from a larger cross-sectional study distributed in the Greater Mekong Sub-Region. This study utilized web-based answers from 1468 Thai GBM respondents between the ages of 15-24 years.

RESULTS: Prevalence of depression was over 50%. Across the social groups of interest, those who disclosed to everyone had the lowest depression prevalence. This association was statistically significant for all groups (p<0.050) except for “Family members” (p = 0.052). There was a statistically significant association illustrated between full disclosure to social groups and increased social support. Most respondents (43.9%) had low social support, and additionally this group had the highest level of depression, compared to those with high social support. There was a statistically significant association for lowered depression outcomes and increased social support. IPV experiences that occurred within the last six months had a statistically significant relationship with depression (p = 0.002). There was a notable association between those with experiences of being a victim of IPV, alone and in conjunction with experience of being a perpetrator of IPV, which was associated with increased odds of depression. However, the type of IPV experiences an individual had did not differ based on disclosure status.

DISCUSSION: This study provides strengthened evidence of the impact that differences in supportive networks can have on mental health outcomes. In addition, they provided a wider consideration for how people may have different IPV experiences, either as a perpetrator, victim, or both, and how those shapes health outcomes of depression. GBM communities still face adversity and challenges that affect their long-term health outcomes, even if they do live in what is considered an accepting country.

ABSTRACT

BACKGROUND: Depression in adolescents is a large and growing problem; however, access to effective mental health care continues to be a challenge. Digitally based interventions may serve to bridge this access gap for adolescents in need of care. Digital interventions that deliver components of cognitive behavioral therapy (CBT) have been shown to reduce symptoms of depression, and virtual reality (VR) may be a promising adjunctive component. However, research on these types of treatments in adolescents and young adults is limited.

OBJECTIVE: This study aims to evaluate the feasibility, acceptability, and preliminary efficacy of Spark (v1.0), a 5-week, self-guided, CBT-based digital program using a mobile app and VR experiences to target symptoms of depression in adolescents.

METHODS: A single-arm, open-label study of the Spark program was conducted with a community sample of 30 adolescents and young adults aged 12 to 21 years with self-reported moderate to severe depression symptoms. Participants completed a weekly depression assessment (Patient Health Questionnaire-8) in the app during the 5-week intervention period as well as web-based baseline, postintervention, and 1-month follow-up self-report assessments. The participants also completed a qualitative postintervention interview. For participants aged <18 years, caregivers completed assessments at baseline and postintervention time points. Feasibility outcomes included recruitment rate (the proportion of participants who enrolled in the study divided by the total number of participants screened for eligibility) and retention rate (the proportion of participants who completed postintervention assessments divided by the total number of participants who received the intervention). Acceptability outcomes included engagement with the program and quantitative and qualitative feedback about the program. Preliminary efficacy was evaluated based on the Patient Health Questionnaire-8.

RESULTS: The study recruitment (31/66, 47%) and retention (29/30, 97%) rates were high. Participants provided higher ratings for the ease of use of the Spark program (8.76 out of 10) and their enjoyment of both the mobile app (7.00 out of 10) and VR components (7.48 out of 10) of the program, whereas they provided lower ratings for the program’s ability to improve mood (4.38 out of 10) or fit into their daily routines (5.69 out of 10). We observed a clinically and statistically significant reduction in depression scores at postintervention (mean difference 5.36; P<.001) and 1-month follow-up (mean difference 6.44; P<.001) time points.

CONCLUSIONS: The Spark program was found to be a feasible and acceptable way to deliver a self-guided CBT-focused intervention to adolescents and young adults with symptoms of depression. Preliminary data also indicated that the Spark program reduced the symptoms of depression in adolescents and young adults. Future studies should evaluate the efficacy of this intervention in an adequately powered randomized controlled trial.

ABSTRACT

BACKGROUND: Self-management (SM) plays an important role in supporting patients’ adaptation to and management of the symptoms of chronic diseases. Cancer is a chronic disease that requires patients to have responsibility in management. Digital technology has the potential to enhance SM support, but there is little data on what SM skills are most commonly supported by digital technology.

OBJECTIVE: This review aimed to examine the SM core skills that were enabled and supported by digital interventions in people with cancer and identify any predictors of the effect of digital health intervention on SM core skills.

METHODS: Three electronic databases (MEDLINE, Scopus, and CINAHL) were searched for papers, published from January 2010 to February 2022, that reported randomized controlled trials (RCTs) involving patients with cancer or survivors of cancer where a digital technology intervention was evaluated and change in 1 or more SM core skills was a measured outcome.

RESULTS: This systematic review resulted in 12 studies that were eligible to identify which SM core skills were enabled and supported by digital intervention. The total number of participants in the 12 studies was 2627. The most common SM core skills targeted by interventions were decision-making, goal setting, and partnering with health professionals. A total of 8 (67%) out of 12 RCTs demonstrated statistically significant improvement in outcomes including self-efficacy, survivorship care knowledge and attitude, quality of life, increased knowledge of treatment, and emotional and social functioning. A total of 5 (62%) out of 8 positive RCTs used theoretical considerations in their study design; whereas in 1 (25%) out of 4 negative RCTs, theoretical considerations were used. In 3 studies, some factors were identified that were associated with the development of SM core skills, which included younger age (regression coefficient [RC]=-0.06, 95% CI -0.10 to -0.02; P=.002), computer literacy (RC=-0.20, 95% CI -0.37 to -0.03; P=.02), completing cancer treatment (Cohen d=0.31), male sex (SD 0.34 in social functioning; P=.009), higher education (SD 0.19 in social functioning; P=.04), and being a recipient of chemotherapy (SD 0.36 in depression; P=.008). In all 3 studies, there were no shared identical factors that supported the development of SM core skills, whereby each study had a unique set of factors that supported the development of SM core skills.

CONCLUSIONS: Digital technology for patients with cancer appears to improve SM core skills including decision-making, goal setting, and partnering with health care partners. This effect is greater in people who are younger, male, educated, highly computer literate, completing cancer treatment, or a recipient of chemotherapy. Future research should focus on targeting multiple SM core skills and identifying predictors of the effect of digital technology intervention.
