Influence of tobacco chewing on oral health: A hospital-based cross-sectional study in Odisha

Background: Smokeless tobacco use in the Indian subcontinent is a part of many religious and cultural rituals and has gained a degree of social acceptance. The deleterious effects of smokeless tobacco are not as well-known as those produced by smoking. Objectives: The study was carried out to assess the influence of tobacco chewing on the oral health of adult patients attending the dental outpatients department of Khordha district headquarter, Odisha. Methods: A hospital-based cross-sectional study was conducted among 25–64-year-old patients attending the dental outpatient department of Gopabandhu Khordha district headquarter hospital. A total of 512 study participants, who were age and sex matched, were stratified into four age groups such as 25–34 years, 35–44 years, 45–54 years, and 55–64 years old. Oral health status of the participants was assessed using modified WHO Oral Health Assessment Form (2013). Pearson's Chi-square test, binary and multinomial logistic regression was performed to determine the relationship between oral health problems and tobacco chewing. Results: Among the tobacco chewers, 59.8% had gingival bleeding, 40.6% had periodontal pockets, 30.1% had loss of attachment, 48.4% had attrition, and 4.3% had potentially malignant disorders. Compared to the nonchewers, these oral problems were significantly higher among the chewers. Whereas dental caries experience was significantly lower among the chewers (40.6%) compared to the nonchewers (54.7%). Compared to the nonchewers, chewers had 1.71 times increased odds for gingival bleeding, 1.71 times increased odds for periodontal pockets, 2.39 times increased odds for loss of attachment, and 2.49 times increased odds for attrition, which were statistically significant. Conclusion: Hence, the study revealed that tobacco chewing definitely had an influence on oral health, with statistically significant increase in oral health problems in chewers compared to nonchewers. Moreover, loss of attachment and potentially malignant disorders increased significantly with the frequency of tobacco chewing. Periodontal pockets, attrition, and loss of attachment significantly increased with the duration of the chewing habit.
Childhood Cognition and Age-Related Change in Standing Balance Performance From Mid to Later Life: Findings From a British Birth Cohort

Abstract Background Cognitive processing plays a crucial role in the integration of sensory input and motor output that facilitates balance. However, whether balance ability in adulthood is influenced by cognitive pathways established in childhood is unclear, especially as no study has examined if these relationships change with age. We aimed to investigate associations between childhood cognition and age-related change in standing balance between mid and later life. Methods Data on 2,380 participants from the MRC National Survey of Health and Development were included in analyses. Repeated measures multilevel models estimated the association between childhood cognition, assessed at age 15, and log-transformed balance time, assessed at ages 53, 60–64, and 69 using the one-legged stand with eyes closed. Adjustments were made for sex, death, attrition, anthropometric measures, health conditions, health behaviors, education, other indicators of socioeconomic position (SEP), and adult verbal memory. Results In a sex-adjusted model, 1 standard deviation increase in childhood cognition was associated with a 13% (95% confidence interval: 10, 16; p < .001) increase in balance time at age 53, and this association got smaller with age (cognition × age interaction: p < .001). Adjustments for education, adult verbal memory, and SEP largely explained these associations. Conclusions Higher childhood cognition was associated with better balance performance in midlife, with diminishing associations with increasing age. The impact of adjustment for education, cognition and other indicators of SEP suggested a common pathway through which cognition is associated with balance across life. Further research is needed to understand underlying mechanisms, which may have important implications for falls risk and maintenance of physical capability.
Barriers to and enablers of the implementation of an ICF-based intake tool in clinical otology and audiology practice—A qualitative pre-implementation study

The authors are developing an intake tool based on the Brief International Classification of Functioning Disability and Health Core Set for Hearing Loss, by operationalizing its categories into a Patient Reported Outcome Measure. This study was aimed at identifying enablers and barriers to using this tool as perceived by hearing health professionals (HHPs) and patients. Focus groups and interviews were held with HHPs (ENT surgeons, N = 14; audiologists, N = 8) and patients (N = 18). Interview questions were based on the Capability-Opportunity-Motivation-Behavior (COM-B) model. Using the COM-B model and the Theoretical Domains Framework (TDF), transcript fragments were divided into meaning units, which were then categorized into capability-, opportunity- and motivation-related barriers and enablers. These were further specified into TDF domains. HHP barriers included: lack of time to use the tool (O); and fear of being made responsible for addressing any emerging problems, which may be outside the expertise of the HHP (M). Enablers included integration of the tool in the electronic patient record (O); opportunity for the patient to be better prepared for the intake visit (M); and provision of a complete picture of the patient’s functioning via the tool (M). Patient’ barriers included fear of losing personal contact with the HHP (M); and fear that use of the tool might negatively affect conversations with the HHP (M). Enablers included knowledge on the aim and relevance of the tool (C); expected better self-preparation (M); and a more focused intake (M). These findings suggest that an intervention is needed to enhance HHPs’ knowledge, skills and motivation regarding the relevance and the clinical usefulness of the tool. Providing clear and specific information on the purpose of the tool can also enhance patient motivation. For both HHPs and patients, opportunities relating to the (digital) administration and the design of the tool provide additional targets for successful implementation.
Childhood-onset growth hormone deficiency and the transition to adulthood: current perspective

Childhood-onset growth hormone deficiency (CO-GHD) is an endocrine condition associated with a broad range of health issues from childhood through to adulthood, which requires particular attention during the transition period from adolescence to young adulthood. There is uncertainty in the clinical practice of the management of CO-GHD during transition regarding the clinical assessment and management of individual patients during and after transition to obtain optimal follow-up and improved health outcomes. Despite the availability of clinical guidelines providing the framework for transition of young adults with CO-GHD, there remains substantial variation in approaching transitional care among pediatric and adult services. A well-structured and coordinated transitional plan with clear communication and direct collaboration between pediatric and adult health care to ensure optimal management of adolescents with CO-GHD during transition is needed.
A Region-Based Gauss-Newton Approach to Real-Time Monocular Multiple Object Tracking

We propose an algorithm for real-time 6DOF pose tracking of rigid 3D objects using a monocular RGB camera. The key idea is to derive a region-based cost function using temporally consistent local color histograms. While such region-based cost functions are commonly optimized using first-order gradient descent techniques, we systematically derive a Gauss-Newton optimization scheme which gives rise to drastically faster convergence and highly accurate and robust tracking performance. We furthermore propose a novel complex dataset dedicated for the task of monocular object pose tracking and make it publicly available to the community. To our knowledge, it is the first to address the common and important scenario in which both the camera as well as the objects are moving simultaneously in cluttered scenes. In numerous experiments—including our own proposed dataset—we demonstrate that the proposed Gauss-Newton approach outperforms existing approaches, in particular in the presence of cluttered backgrounds, heterogeneous objects and partial occlusions.
Declining prevalence of hepatitis C virus among university students in one of the main governorates in Egypt

Background and aims Egypt is considered to have the highest rate of hepatitis C virus (HCV) prevalence worldwide. However, HCV prevalence is currently declining due to the improvement of health education programs, improved environmental sanitation, and the introduction of novel treatment regimens. The aim of this work was to determine the HCV seroprevalence among Menoufia University students. Methods The current study included 48,972 students from Menoufia University, Egypt. Blood sample was obtained from every patient for HCV seromarker testing. In anti-HCV-positive subjects, quantitative PCR for HCV RNA was done. Results Overall, HCV antibody prevalence rate was 1%. This prevalence was higher in females (304/27,421; 1.1%) than in males (194/21,371; 0.9%). HCV-RNA PCR was positive in 355/48,972 (0.7%); the percentage of HCV PCR positive among the anti-HCV-positive was 71.3% (355/498 patients), with a higher prevalence among females than in males but without statistical significance. In addition, rural areas showed more prevalent HCV seroprevalence than urban areas. Conclusion These prevalence rates for HCV infection are lower than that previously reported in the same age group denoting a new evidence for the reduction of prevalence and a hope for successful eradication of HCV in the forthcoming years.
Does Emotional Intelligence Mediate the Relation Between Mindfulness and Anxiety and Depression in Adolescents?

High anxiety and depression are often observed in the Australian adolescent population, and if left untreated, can have long-term negative consequences impacting educational attainment and a range of important life outcomes. The utilization of mindfulness techniques has been associated with decreased anxiety and depression, but the underlying mechanisms for this is only beginning to be understood. Previous research with adult samples has suggested that the development of emotional intelligence (EI) may be one mechanism by which mindfulness confers its benefits on wellbeing. This study is the first to examine the relation between mindfulness, EI, anxiety, and depression in an adolescent population. It was hypothesized that EI would mediate the relationships between mindfulness and anxiety, as well as mindfulness and depression. The sample consisted of 108 adolescents from a public secondary school, aged between 13 and 15 years (Mage = 13.68, SDage = 0.56, 51 males and 57 females). Participants completed an online self-report questionnaire which measured dispositional mindfulness, EI, anxiety, and depression. The results indicated that one subscale of EI – Emotional Recognition and Expression (ERE) mediated the relation between mindfulness and anxiety, while two subscales of EI – ERE and Emotional Management and Control (EMC) mediated the relation between mindfulness and depression. Future research utilizing a mindfulness intervention should be conducted to examine whether the use of mindfulness increases EI and decreases anxiety and depression in adolescents.
The Emergent Course of Bipolar Disorder: Observations Over Two Decades From the Canadian High-Risk Offspring Cohort.

OBJECTIVE: The authors sought to describe the emergent course of bipolar disorder in offspring of affected parents subgrouped by parental response to lithium prophylaxis. METHODS: Parent bipolar disorder was confirmed by the best-estimate procedure and lithium response by research protocol. High-risk offspring (N=279) and control subjects (N=87) were blindly assessed, annually on average, with the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime version or the Schedule for Affective Disorders and Schizophrenia-Lifetime version. DSM-IV diagnoses were confirmed using the best-estimate procedure in blind consensus reviews. Cumulative incidence and median age at onset were determined for lifetime syndrome- and symptom-level data. Mixed models assessed the association between parent and offspring course. A multistate model was used to estimate the clinical trajectory into bipolar disorder. RESULTS: The cumulative incidence of bipolar disorder was 24.5%, and the median age at onset was 20.7 years (range, 12.4 to 30.3). The clinical course of the affected parent was associated with that of the affected child. Depressive episodes predominated during the early bipolar course, especially among offspring of lithium responders. Childhood sleep and anxiety disorders significantly predicted 1.6-fold and 1.8-fold increases in risk of mood disorder, respectively, and depressive and manic symptoms predicted 2.7-fold and 2.3-fold increases in risk, respectively. The best-fit model of emerging bipolar disorder was a progressive sequence from nonspecific childhood antecedents to adolescent depression to index manic or hypomanic episode. Subthreshold sleep symptoms were significantly associated with transition from well to non-mood disorder, and psychotic symptoms in mood episodes were significantly associated with transition from unipolar to bipolar disorder. CONCLUSIONS: Bipolar disorder in individuals at familial risk typically unfolds in a progressive clinical sequence. Childhood sleep and anxiety disorders are important predictors, as are clinically significant mood symptoms and psychotic symptoms in depressive episodes.
Notoginsenoside R1 Protects HUVEC Against Oxidized Low Density Lipoprotein (Ox-LDL)-Induced Atherogenic Response via Down-Regulating miR-132

Background/Aims: Radix notoginseng is a well-known traditional Chinese herbal medicine, has extensively pharmacological activities in cardiovascular system. Notoginsenoside R1 (NGR1) is one main active ingredient of Radix notoginseng. The purpose of this study was to evaluate the functional effects of NGR1 on atherosclerosis (AS). Methods: Human umbilical vascular endothelial cells (HUVECs) were subjected to oxidized low density lipoprotein (ox-LDL), before which cells were preconditioned with NGR1. Cell Counting Kit-8 (CCK-8) assay, flow cytometry, Transwell assay, quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot were carried out to assess the impacts of ox-LDL and NGR1 on HUVECs. Besides, the expression of microRNA-132 (miR-132), and the regulatory role of miR-132 in Matrix Gla Protein (MGP) expression were measured by qRT-PCR and Western blot. Results: NGR1 pre-conditioning prevented ox-LDL-induced apoptosis, migration and overproduction of Monocyte Chemoattractant Protein 1 (MCP-1) and Intercellular Adhesion Molecule 1 (ICAM-1). miR-132 was up-regulated in response to ox-LDL while was down-regulated by NGR1 pre-conditioning. The protective actions of NGR1 in ox-LDL-treated HUVECs were enhanced by miR-132 inhibitor, while were attenuated by miR-132 mimic. Besides, the up-regulated miR-132 could further decrease the expression of MGP, which acted as an anti-migratory and anti-adhesive factor. Furthermore, ox-LDL-induced the activation of c-Jun N-terminal Kinase (JNK) and Nuclear Factor Kappa B (NF-κB) pathways were partially attenuated by NGR1, and were fully eliminated by NGR1 treatment together with MGP overexpression. Conclusion: NGR1 prevents ox-LDL-induced apoptosis, migration and adhesion-related molecule release in HUVECs possibly via down-regulating miR-132, and subsequent up-regulating MGP.
Dynamics of Cas10 Govern Discrimination between Self and Nonself in Type III CRISPR-Cas Immunity

Adaptive immune systems are required to accurately distinguish between self and nonself in order to defend against invading pathogens while avoiding autoimmunity. Type III CRISPR-Cas systems employ guide RNAs that recognize complementary RNA molecules to trigger the degradation of both the target transcript and its template DNA. These systems can broadly eliminate foreign targets with multiple mutations, but still effectively curb immunity against the host. The molecular basis for these unique features remains unknown. Here we use single-molecule fluorescence microscopy to study the interaction between a type III-A ribonucleoprotein complex and various RNA substrates. We find that Cas10—the DNase effector of the complex—displays rapid conformational fluctuations on foreign RNA targets, but is locked in a static configuration on self RNA. Single-stranded DNA promotes Cas10’s occupancy at a selected set of conformational states, which is also sensitively modulated by target mutations and predictive of CRISPR interference activity. These findings highlight the central role of the internal dynamics of CRISPR-Cas complexes in self/nonself discrimination and target specificity.
A novel standardised side hop test reliably evaluates landing mechanics for anterior cruciate ligament reconstructed persons and controls

ABSTRACT We propose a novel one-leg standardised rebound side-hop test (SRSH) specifically designed for detailed analysis of landing mechanics. Anterior cruciate ligament reconstructed persons (ACLR, n = 30) and healthy-knee controls (CTRL, n = 30) were tested for within-session and test-retest (CTRL only, n = 25) reliability and agreement. Trunk, hip and knee angles and moments in sagittal, frontal, and transversal planes during landing, including time to stabilisation (TTS), were evaluated using intra-class correlations (ICCs), average within-person standard deviations (SW) and minimal differences. Excellent within-session reliability were found for angles in both groups (most ICCs > 0.90, SW ≤ 5°), and excellent to good for moments (most ICCs > 0.80, SW ≤ 0.34 Nm/kg). Only knee internal rotation moment showed poor reliability (ICC < 0.4). Test-retest results were excellent to fair for all angles and moments (ICCs 0.47–0.91, SW < 5° and ≤ 0.25 Nm/kg), except for peak trunk lateral bending angle and knee internal rotation moment. TTS showed excellent to fair within-session reliability but poor test-retest results. These results, with a few exceptions, suggest promising potential of evaluating landing mechanics during the SRSH for ACLR and CTRL, and emphasise the importance of joint-specific movement control variables in standardised tasks.
Methicillin‐resistant Staphylococcus aureus in urban Norway rat (Rattus norvegicus) populations: Epidemiology and the impacts of kill‐trapping

Urban Norway rat (Rattus norvegicus) populations can carry the bacteria methicillin‐resistant Staphylococcus aureus (MRSA). There are numerous knowledge gaps in the epidemiology of MRSA in these populations that limit understanding of its ecology in urban environments. For example, fecal shedding of MRSA, which may increase environmental contamination, has been reported in other species; however, it is unknown whether Norway rats carry the bacteria rectally. Furthermore, while intermittent MRSA shedding has been shown in other species and may dictate when the risk of transmission is highest, duration of carriage has not been examined for Norway rats. Previous work has shown that lethal animal‐control methods may increase the level of pathogens within reservoir populations, possibly by disrupting ecological patterns. However, the impact of rodent‐control on potentially environmentally acquired pathogens like MRSA has not been tested. Using capture‐mark‐recapture methods in an inner‐city neighborhood in Vancouver, Canada, we show that rats intermittently carry MRSA both in the rectum and oropharynx. By assessing the prevalence of MRSA before and after enacting a pest‐control intervention, we report that kill‐trapping had no impact on the prevalence of carriage of this environmentally‐acquired agent.
Dynamic cerebral autoregulation measurement using rapid changes in head positioning: experiences in acute ischemic stroke and healthy control populations.

The ideal technique for dynamic cerebral autoregulation (dCA) assessment in critically ill patients should provide considerable variability in blood pressure (BP) but without the need for patient cooperation. We proposed using rapid head positioning (RHP) over spontaneous BP fluctuations for dCA assessment in patients with acute ischemic stroke (AIS). Cerebral blood velocity (transcranial Doppler), beat-to-beat BP (Finometer), and end-tidal CO2 (capnography) were recorded during 5-min baseline and RHP in 16 controls (8 women and 8 men, mean age: 57 ± 16 yr) and 15 patients with AIS (7 women and 8 men, mean age: 69 ± 8 yr) at two (12 ± 8 days) and three visits (13.3 ± 6.9 h, 4.8 ± 3.2 days, and 93.9 ± 11.5 days from the symptom onset), respectively. All participants were able to complete the RHP protocol without difficulty. Compared with controls, patients with AIS were hypocapnic (all visits, P < 0.0024) and hypertensive ( visit 1, P = 0.011), although BP gradually reduced after the acute phase. RHP demonstrated greater beat-to-beat BP variability (BPV) in controls ( visits 1 and 2, P < 0.001) but not in patients with AIS at any visit. Compared with controls, a reduced autoregulation index (ARI) was demonstrated in patients with AIS, at visit 2 for the baseline recording but not at other visits or during RHP. The area under the receiver-operating curve was 0.53 and 0.54 for baseline and RHP, respectively. The RHP paradigm required minimal patient cooperation and could be considered a feasible alternative for assessing dCA, mainly in conditions leading to increased BPV. The lack of BPV increase in AIS with RHP deserves further investigation. NEW & NOTEWORTHY This study used rapid head positioning (RHP) to enhance blood pressure (BP) variability (BPV) to improve BP signal-to-noise ratio and reliability of dynamic cerebral autoregulation (dCA). RHP was well accepted by controls and acute ischemic stroke (AIS); the increased BPV induced in controls was not observed in AIS, suggesting BPV at rest was already elevated. RHP did not improve detection of impaired CA in AIS; further work is needed to understand the different responses observed.
