Review
A growing body of research suggested that there was a link between poor periodontal health and systemic diseases, particularly with the early development of cognitive disorders, dementia, and depression. This is especially true in cases of changes in diet, malnutrition, loss of muscular endurance, and abnormal systemic inflammatory response. Our study aimed to determine the extent of these associations to better target the multi-level healthy aging challenge investigating the impact of periodontal disease on cognitive disorders (cognitive impairment and cognitive decline), dementia, and depression. We conducted a comprehensive literature search up to November 2023 using six different electronic databases. Two independent researchers assessed the eligibility of 7363 records against the inclusion criteria and found only 46 records that met the requirements. The study is registered on PROSPERO (CRD42023485688). We generated random effects pooled estimates and 95% confidence intervals (CI) to evaluate whether periodontal disease increased the risk of the investigated outcomes. The quality assessment revealed moderate quality of evidence and risk of bias. Periodontal disease was found to be associated with both cognitive disorders (relative risk (RR) 1.25, 95% CI 1.11-1.40, in the analysis of cross-sectional studies); cognitive impairment (RR 3.01, 95% CI 1.52-5.95 for longitudinal studies, cognitive decline); and dementia (RR 1.22, 95% CI 1.10-1.36). However, no significant increased risk of depression among subjects with periodontal disease was found (RR 1.07, 95% CI 0.95-1.21). Despite the association with two of the three explored outcomes, the available evidence on periodontal diseases and dementia, cognitive disorders, and depression is controversial due to several limitations. Therefore, further investigations involving validated and standardized tools are required.

Crop migration can moderate the impacts of global warming on crop production, but its feedback on the climate and environment remains unknown. Here we develop an integrated framework to capture the climate impacts and the feedback of adaptation behaviours with the land-water-energy-carbon nexus perspective and identify opportunities to achieve the synergies between climate adaptation and environmental sustainability. We apply the framework to assess wheat and maize migration in the North China Plain and show that adaptation through wheat migration could increase crop production by ~18.5% in the 2050s, but at the cost of disproportional increment in land use (~19.2%), water use (~20.2%), energy use (~19.5%) and carbon emissions (~19.9%). Irrigation and fertilization management are critical mitigation opportunities in the framework, through which wheat migration can be optimized to reduce the climatic and environmental impacts and avoid potential carbon leakage. Our work highlights the sustainable climate adaptation to mitigate negative environmental externalities.

Introduction Impacted mandibular third molars can be asymptomatic or cause some pathologies, such as distal caries and odontogenic cysts and tumours. This study investigates the prevalence of distal caries of the mandibular second molar adjacent to the mesioangular or horizontally partially erupted mandibular third molar and its relationship regarding decayed, missing and filled teeth (DMFT) risk group, age, side (left-right) and sex.Methods The study included patients who had an appointment for mesioangular or horizontally positioned and partially erupted mandibular third molar surgery. Before the surgery, the DMFT score, age, sex and side were recorded. After extraction, the second molar was clinically examined for distal caries. The prevalence of distal caries and the correlation between the DMFT risk group, age, sex and side were determined.Results The study was conducted on 514 patients and involved 639 teeth. Men and patients in the moderate- or high-risk group are significantly prone to developing distal caries of the second molar. No statistically significant relationship exists regarding age group, side and position.Conclusion Sex and DMFT risk groups affect the prevalence of distal caries in second molars adjacent to the mesioangular or horizontally partially erupted third molars. The prophylactic extraction should be considered in men and patients in the moderate- or high-risk group.

Metacognitive biases have been repeatedly associated with transdiagnostic psychiatric dimensions of 'anxious-depression' and 'compulsivity and intrusive thought', cross-sectionally. To progress our understanding of the underlying neurocognitive mechanisms, new methods are required to measure metacognition remotely, within individuals over time. We developed a gamified smartphone task designed to measure visuo-perceptual metacognitive (confidence) bias and investigated its psychometric properties across two studies (N = 3410 unpaid citizen scientists, N = 52 paid participants). We assessed convergent validity, split-half and test-retest reliability, and identified the minimum number of trials required to capture its clinical correlates. Convergent validity of metacognitive bias was moderate (r(50) = 0.64, p < 0.001) and it demonstrated excellent split-half reliability (r(50) = 0.91, p < 0.001). Anxious-depression was associated with decreased confidence (β = - 0.23, SE = 0.02, p < 0.001), while compulsivity and intrusive thought was associated with greater confidence (β = 0.07, SE = 0.02, p < 0.001). The associations between metacognitive biases and transdiagnostic psychiatry dimensions are evident in as few as 40 trials. Metacognitive biases in decision-making are stable within and across sessions, exhibiting very high test-retest reliability for the 100-trial (ICC = 0.86, N = 110) and 40-trial (ICC = 0.86, N = 120) versions of Meta Mind. Hybrid 'self-report cognition' tasks may be one way to bridge the recently discussed reliability gap in computational psychiatry.

Journal of Hand Therapy : Official... Jun 2024Debilitating problems with hand function experienced by people with Parkinson's disease (PD) can worsen during multitasking.
BACKGROUND
Debilitating problems with hand function experienced by people with Parkinson's disease (PD) can worsen during multitasking.
PURPOSE
To investigate the effects of dual-task interference on a pegboard task in people with mild to moderately severe PD.
STUDY DESIGN
Descriptive analysis.
METHODS
A secondary analysis of baseline data from the ParkinsonNet physiotherapy study conducted in 2006 in the Netherlands. The 9-hole peg test was performed with the more affected hand under single- and dual-task conditions. In dual-task trials, a cognitive task was added. The patient specific index-Parkinson's disease identified two functional priority groups-those reporting arm and hand problems as a priority for allied health management ("upper extremity priority") and those prioritizing other issues ("other priority"). We investigated differences in single- and dual-task performance at different levels of disease severity (Hoehn and Yahr stage) and for the two priority groups, and calculated the dual-task effect.
RESULTS
Participants were 566 people with PD (Hoehn and Yahr stages I-IV). Dual-task interference occurred at each disease stage. Significant interactions existed between the task condition and disease severity (F (3, 559) = 4.28, p = 0.005) and task condition and priority group (F (1, 561) = 4.44, p = 0.036). Dual-task interference was greater in participants with more advanced disease or those prioritizing upper extremity problems.
CONCLUSION
We described the effects of dual-task interference on more affected hand performance of a standardized dexterity test in a broad sample of people with PD. Dual-task interference may impact the daily lives of people with PD, especially those with more severe disease or who report arm and hand problems. It is important for clinicians to consider dual-task interference during upper extremity assessment and treatment.

OBJECTIVE
The objective of this study is to assess the accuracy of the Mimi Hearing Test (MHT) mobile application in the detection of air conduction (AC) thresholds and in screening for moderate hearing loss.
STUDY DESIGN
Prospective clinical study.
SETTING
Tertiary care center.
PATIENTS
Participants with or without a varying degree of hearing loss, aged 18 years and over, without cognitive impairment and without active otorrhea or earwax impaction at the time of the hearing assessment were included.
INTERVENTION
Subjects with a ranging severity of hearing loss underwent a conventional in-booth audiogram as well as mobile-based screening with MHT in a quiet room (45.5 dB background noise) on the same day. Both regular over-the-ear and noise-canceling headphones were tested with MHT.
MAIN OUTCOME MEASURES
Comparisons of AC thresholds between conventional audiometry and mobile-based audiometry at discrete frequencies and with pure-tone averages (PTA) were performed.
RESULTS
A total of 75 adults (mean age: 56.2 yr, 54.7% male) were recruited and 63 used for analysis. Of the thresholds measured with MHT using regular headphones, 44.0% were within 10 dB of the conventional audiogram, compared to 39.3% using noise-canceling headphones. MHT demonstrated best accuracy at high frequencies (4-8 kHz). When screening for moderate hearing loss (PTA >40 dB HL), MHT demonstrated a sensitivity and specificity of 100.0% and 80.2%, respectively.
CONCLUSIONS
MHT is reliable for identifying moderate hearing loss but lacks precision in detecting thresholds at low frequencies. Noise canceling headphones seem to improve its precision at 4,000 Hz only.

Randomized Controlled Trial
Nipocalimab, an anti-FcRn monoclonal antibody, in participants with moderate to severe active rheumatoid arthritis and inadequate response or intolerance to anti-TNF therapy: results from the phase 2a IRIS-RA study.
OBJECTIVES
To investigate the efficacy, safety, pharmacokinetics and pharmacodynamics of nipocalimab in participants with moderate to severe active rheumatoid arthritis (RA) and inadequate response or intolerance to ≥1 antitumour necrosis factor agent.
METHODS
In this phase 2a study, participants with RA seropositive for anticitrullinated protein antibodies (ACPA) or rheumatoid factors were randomised 3:2 to nipocalimab (15 mg/kg intravenously every 2 weeks) or placebo from Weeks 0 to 10. Efficacy endpoints (primary endpoint: change from baseline in Disease Activity Score 28 using C reactive protein (DAS28-CRP) at Week 12) and patient-reported outcomes (PROs) were assessed through Week 12. Safety, pharmacokinetics and pharmacodynamics were assessed through Week 18.
RESULTS
53 participants were enrolled (nipocalimab/placebo, n=33/20). Although the primary endpoint did not reach statistical significance for nipocalimab versus placebo, a numerically higher change from baseline in DAS28-CRP at Week 12 was observed (least squares mean (95% CI): -1.03 (-1.66 to -0.40) vs -0.58 (-1.24 to 0.07)), with numerically higher improvements in all secondary efficacy outcomes and PROs. Serious adverse events were reported in three participants (burn infection, infusion-related reaction and deep vein thrombosis). Nipocalimab significantly and reversibly reduced serum immunoglobulin G, ACPA and circulating immune complex levels but not serum inflammatory markers, including CRP. ACPA reduction was associated with DAS28-CRP remission and 50% response rate in American College of Rheumatology (ACR) criteria; participants with a higher baseline ACPA had greater clinical improvement.
CONCLUSIONS
Despite not achieving statistical significance in the primary endpoint, nipocalimab showed consistent, numerical efficacy benefits in participants with moderate to severe active RA, with greater benefit observed for participants with a higher baseline ACPA.

INTRODUCTION
To determine the prevalence and associated factors of scabies among the children living in the Madrasahs (Islamic religious educational institution) of Bangladesh was the objective of the study.
METHODS
This cross-sectional study was conducted in eight selected Madrasahs from May to October 2023 among male and female children aged between 3 and 18 years. Children were screened for scabies according to criteria developed by the International Alliance for the Control of Scabies.
RESULTS
It was found that overall prevalence of scabies among the children living in Madrasahs was almost 34% (mild 73.5%, moderate 24.9% and severe 1.6%). Prevalence of scabies among male was higher than female (39.4% vs 28.4%). Male gender (aOR 2.09, 95% CI 1.27 to 3.47, p=0.004) and age (aOR 0.95, 95% CI 0.91 to 0.99, p=0.017) were two significant predictors of scabies among children. Besides, living in Madrasahs having more boarders (aOR 1.37, 95% CI 1.06 to 1.69, p=0.025), shared bedding, clothes or toilet stuffs with other children (aOR 1.46, 95% CI 1.03 to 2.09, p=0.036) and history of pruritus in the close entourage (aOR 4.19, 95% CI 3.07 to 5.73, p<0.001) were associated with a higher chance of being infected by scabies.
CONCLUSION
Almost one-third of the children living in the Islamic boarding schools in Bangladesh are suffering from scabies, more prevalence in male and younger children. Accommodation of higher number of boarders, sharing personal staffs and pruritus in close contacts increase the risk of scabies in these children.

Journal of the American Board of Family... Jun 2024Practice facilitation supports practice change in clinical settings. Despite its widespread use little is known about how facilitators enable change.
BACKGROUND
Practice facilitation supports practice change in clinical settings. Despite its widespread use little is known about how facilitators enable change.
OBJECTIVE
This study identifies which implementation strategies practice facilitators used and the frequency of their use in a study to improve the quality of cardiovascular care in primary care.
DESIGN
Cross-sectional analysis of data collected by practice facilitators in the Healthy Hearts Northwest (H2N) study.
PARTICIPANTS
Notes collected by facilitators in the H2N study.
APPROACH
We coded these field notes for a purposeful sample of 44 practices to identify Expert Recommendations for Implementation Change (ERIC) strategies used with each practice and calculated the proportion of practices where each implementation strategy was coded at least once. Strategies were categorized as foundational (used in 80% to 100% of practices), moderately used (20%-<80% of practices), rarely used (1-[Formula: see text]% of practices), or absent (0%).
KEY RESULTS
We identified 26 strategies used by facilitators. Five strategies were foundational: Develop and/or implement tools for quality monitoring, Assess barriers that may impede implementation, Assess for readiness or progress, Develop and support teams, and Conduct educational meetings.
CONCLUSIONS
Commonly used strategies can help guide development of the core components of practice facilitation strategies.

The clear public messaging from international health authorities is that individuals should "sit less and move more." While it is acknowledged that this guidance needs to be tailored to the age of people and also to their health, and abilities, the guidance is not tailored to their current level of physical behaviors. This opinion piece aims to highlight that although people with excessive sitting and insufficient moderate-to-vigorous physical activity should sit more and move less, for other people their health would be promoted by sitting more and moving less. Thus, physical behaviors are not always "poison" or "medicine," but rather the health impact of changes in physical behaviors depends on people's initial levels. Policy, research, and practice implications of this realization are presented. Only tailoring messaging to age and health status could be far from optimal for people with very different current levels of physical behaviors. Policy, research, and practice will be enhanced when the potential for physical behaviors to be either health hindering or health promoting is adequately considered.
