The study reveals that this model achieves an average recognition rate of 99.81% for dynamic ASL gestures. Moreover, the proposed ASL recognition system can be further integrated with ICT and IoT technology to provide a feasible solution to assist hearing-impaired people in communicating with others and improve their quality of life.

The oral health of elderly populations is a significant concern, as it is closely linked to general health and health-related quality of life. Poor oral health exacerbates oral diseases, leading to an increased risk of non-communicable diseases and self-care dependence, particularly in the elderly, worldwide. Knowledge, attitudes, and practices (KAP) play influential roles in individual oral care. However, the evidence of KAP related to oral care among the elderly is still inadequate.

This study aimed to examine KAP and their associated factors related to oral care among the elderly community.

A cross-sectional descriptive design was used. The eligible subjects were recruited, using convenience sampling and snowball sampling.

A total of 385 elderly individuals were included, and 51.4% were women. The mean age was 71.66 (SD 6.28). Knowledge was reportedly poor, as more than 50% elderly answered several questions incorrectly. The mean attitude and practices scores were 44.94 (SD 6.33) and 68.90 (SD 10.4ional program containing oral health knowledge should be offered to at-risk groups. Family support and involvement are also important for improving oral care among elderly individuals.

Based on the KAP theoretical model, KAP are closely interrelated. Identified factors associated with KAP are useful to understand at-risk groups. Elderly individuals at lower education levels, with poor family support and inadequate self-care independence, have poor KAP related to oral care. Therefore, this study improves insight for health promotion developers, suggesting that more attention should be paid to at-risk elderly groups' oral health. To enhance participation in dental care and improve oral care performance in the elderly, educational program containing oral health knowledge should be offered to at-risk groups. Family support and involvement are also important for improving oral care among elderly individuals.There is a growing optimism about the potential of new disease-modifying therapies (DMTs) in the management of relapsing-remitting multiple sclerosis (RRMS) patients. However, this initial enthusiasm has been tempered by evidence indicating that multiple sclerosis (MS) patients undergoing DMT may be at higher risk of developing infections through incompletely understood mechanisms. As neutrophils provide the first line of defense against pathogens, here we have compared the effects of some of the commonly used MS DMTs (i.e., moderate-efficacy injective, first-line interferonβ-1b (IFNβ-1b), glatiramer acetate (GA); and high-efficacy, second-line fingolimod (FTY) and natalizumab (NAT)) on the in vitro viability and functions of neutrophils isolated from healthy subjects. All the DMTs tested impaired the ability of neutrophils to kill Klebsiella pneumoniae, whereas none of them affected the rate of neutrophil apoptosis or CD11b and CD62L cell surface expression. Intriguingly, only FTY exposure negatively affected K. pneumoniae-induced production of reactive oxygen species (ROS) in polymorphonuclear leukocytes (PMNs). click here Furthermore, neutrophils exposed to K. pneumoniae secreted enhanced amounts of CXCL8, IL-1β and TNF-α, which were differentially regulated following DMT pretreatment. Altogether, these findings suggest that DMTs may increase the susceptibility of MS patients to microbial infections, in part, through inhibition of neutrophil functions. In light of these data, we recommend that the design of personalized therapies for RRMS patients should take into account not just the mechanism of action of the chosen DMT but also the potential risk of infection associated with the administration of such therapeutic compounds to this highly vulnerable population.The present study aims to examine the relationship between psychological strain, suicidal ideation, hopelessness, and depression among Chinese athletes. Participants were 774 Chinese athletes (454 men and 320 women), with a range of ages from 12 to 35 (M = 18.47, SD = 3.39). The structural equation modeling method was used to examine the multiple mediating effects of hopelessness and depression between psychological strain and suicidal ideation. As expected, a positive correlation between psychological strain, suicidal ideation, hopelessness, and depression was found. Additionally, results seem to indicate that psychological strain directly and positively influenced suicidal ideation, and that hopelessness and depression played a serial mediating role in the relationship between psychological strain and suicidal ideation. To conclude, the psychological strain theory is applicable for explaining suicidal ideation in athletes. In athletes, psychological strain is sequentially associated first with a sense of hopelessness and then depression, which is in turn related to suicidal ideation. The present study makes a significant contribution to the literature because we provide a new theoretical basis and new methods for preventing mental disorder and suicidality in athletes.Studies of occupational metal exposures and amyotrophic lateral sclerosis (ALS) have focused primarily on known neurotoxicants, including lead, mercury, selenium, and cadmium. However, these exposures are often co-occurring with other lesser studied metals. We conducted a population-based case-control study with the aim of assessing associations between occupational chromium, iron, and nickel exposures and risk of ALS. We identified ALS cases in Denmark from 1982 through 2013 from the Danish National Patient Registry and matched them to 100 controls based on birth year and sex. Cumulative metal exposures were estimated using job exposure matrices applied to occupational history from the Danish Pension Fund. Although mutually adjusted odds of ALS were higher in men with chromium exposures in the third quartile (aOR = 1.24; 95% CI 0.91, 1.69) and fourth quartile (aOR = 1.19; 95% CI 0.80, 1.76) compared to those with no exposure, differences did not reach statistical significance. We also observed higher odds of ALS in women with nickel exposures in the third quartile (aOR = 2.
