Temporomandibular disorders (TMDs) encompass a heterogeneous group of musculoskeletal and neuromuscular conditions affecting the temporomandibular joint (TMJ) and masticatory system. Due to academic stress and parafunctional habits, dental students may be particularly vulnerable to TMD. Objective: To determine the prevalence of TMD symptoms and their psychosocial and functional correlates among students at the Faculty of Dental Medicine, UMPh Iasi, Romania, using the diagnostic criteria for TMD (DC/TMD) self-report axis and axis II instruments. Methods: In this cross-sectional survey, 356 volunteer students (66.0% female; mean age, 22.9 ± 3.6 years) out of a total population of 1874 completed an online DC/TMD–based questionnaire. Axis I assessed orofacial pain, joint noises, and mandibular locking. Axis II instruments included the Graded Chronic Pain Scale (GCPS), Jaw Functional Limitation Scale (JFLS-20), Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Oral Behaviors Checklist (OBC). Descriptive statistics summarized frequencies, means, and standard deviations; χ² tests and t-tests compared subgroups by sex; Pearson correlations explored relationships among continuous measures (α = 0.05). Results: A total of 5% of respondents reported orofacial pain in the past 30 days; 41.6% observed TMJ noises; 19.7% experienced locking episodes. Mean JFLS score was 28.3 ± 30.5, with 4.8% scoring > 80 (severe limitation). Mean PHQ-9 was 5.96 ± 5.37 (mild depression); 15.5% scored ≥ 10. Mean GAD-7 was 5.20 ± 4.95 (mild anxiety); 16.0% scored ≥ 10. Mean OBC score was 12.3 ± 8.5; 30.1% scored ≥ 16, indicating frequent parafunctional habits. Symptom prevalence was similar by sex, except temporal headache (43.4% females vs. 24.3% males; p = 0.0008). Females reported higher mean scores for pain intensity (2.09 vs. 1.55; p = 0.0013), JFLS (32.5 vs. 18.0; p < 0.001), PHQ-9 (6.43 vs. 5.16; p = 0.048), and OBC (13.9 vs. 9.7; p = 0.0014). Strong correlation was observed between PHQ-9 and GAD-7 (r = 0.74; p < 0.001); moderate correlations were observed between pain intensity and PHQ-9 (r = 0.31) or GAD-7 (r = 0.30), between JFLS and pain intensity (r = 0.33), and between OBC and PHQ-9 (r = 0.39) (all p < 0.001). Conclusions: Nearly half of dental students reported TMD symptoms, with appreciable functional limitation and psychosocial impact. Parafunctional behaviors and psychological distress were significantly associated with pain and dysfunction. These findings underscore the need for early screening, stress-management interventions, and interdisciplinary care strategies in the dental student population. Full article

Background/Objectives: Banhasasim-tang (BHSST) is a traditional herbal formula commonly used to treat gastrointestinal (GI) disorders and has been considered a potential therapeutic option for irritable bowel syndrome (IBS). This study aimed to explore the molecular targets and underlying mechanisms of BHSST in IBS using a combination of network pharmacology, molecular docking, molecular dynamics simulations, and in vivo validation. Methods: Active compounds in BHSST were screened based on drug-likeness and oral bioavailability. Potential targets were predicted using ChEMBL, and IBS-related targets were obtained from GeneCards and DisGeNET. A compound–target–disease network was constructed and analyzed via Gene Ontology and KEGG pathway enrichment. Compound–target interactions were further assessed using molecular docking and molecular dynamics simulations. The in vivo effects of eudesm-4(14)-en-11-ol, elemol, and BHSST were evaluated in a zymosan-induced IBS mouse model. Results: Twelve BHSST-related targets were associated with IBS, with enrichment analysis identifying TNF signaling and apoptosis as key pathways. In silico simulations suggested stable binding of eudesm-4(14)-en-11-ol to TNF-α and kanzonol T to PIK3CD, whereas elemol showed weak interaction with PRKCD. In vivo, eudesm-4(14)-en-11-ol improved colon length, weight, stool consistency, TNF-α levels, and pain-related behaviors—effects comparable to those of BHSST. Elemol, however, showed no therapeutic benefit. Conclusions: These findings provide preliminary mechanistic insight into the anti-inflammatory potential of BHSST in IBS. The integrated in silico and in vivo approaches support the contribution of specific components, such as eudesm-4(14)-en-11-ol, to its observed effects, warranting further investigation.

Background/Objectives: Obesity among university students is a growing concern, often influenced by biological, psychological, and social factors. Few studies in Saudi Arabia have addressed this issue using a comprehensive framework. This study aims to examine the prevalence of obesity and its biopsychosocial predictors among university students, as well as their perceptions, behaviors, and comorbidities. Methods: A cross-sectional study was conducted at Jazan University during the 2024–2025 academic year. A total of 819 undergraduate students completed a structured, self-administered Arabic questionnaire. The tool assessed sociodemographic variables, body mass index (BMI) (calculated from self-reported height and weight), biological and psychological factors, social influences, lifestyle behaviors, and comorbidities. Bivariate associations were tested using chi-square analyses, and multivariate logistic regression was used to identify independent predictors of obesity. Results: The prevalence of obesity was 19.6%, and 22.6% of students were overweight. Obesity was significantly more prevalent among males (26.7%) than females (9.6%, p < 0.001) and among students aged 24 years and above (24.0%, p = 0.024). Independent predictors of obesity included being overweight in childhood (AOR = 5.23, 95% CI: 3.47–7.90), belief in a genetic predisposition (AOR = 4.66), emotional eating (AOR = 2.57), academic or personal stress (AOR = 5.36), and social pressures related to body image (AOR = 2.96). Comorbidities significantly associated with obesity included high cholesterol (AOR = 5.40), sleep disorders (AOR = 2.99), and joint pain (AOR = 1.96). More than 80% of students with obesity reported current or past weight loss attempts, and nearly 60% received medical advice to lose weight. Conclusions: Obesity among Jazan University students is significantly associated with male gender, early-life weight history, emotional and academic stress, and social pressures. Students with obesity also experience a higher burden of comorbid conditions, even at a young age. These findings highlight the need for integrated, student-centered interventions that address both the psychological and social dimensions of weight management in university settings. Full article

Experiences of life-threatening stimuli can induce post-traumatic stress disorder (PTSD), which is associated with long-lasting behavioral and neurochemical abnormalities. Despite its increased global incidence, the current treatment options for PTSD remain limited, highlighting the need for novel therapeutic strategies. As oxidative stress and neuroinflammation contribute to PTSD, the use of powerful antioxidants such as thiamine (B1 vitamin) compounds may counteract disease development. Young C57BL/6 mice received thiamine or benfotiamine in drinking water (each at a dose of 200 mg/kg/day) for 21 days, and for the last five days, they were subjected to rat exposure. Mice were studied for anxiety-like behavior, exploration, locomotion, grooming, social interactions, pain sensitivity, brain changes in protein carbonyl (PC), total glutathione (TG), and gene expression of distress and inflammation markers. Rat exposure induced anxiety-like behavior, excessive grooming, and alteration in locomotion, along with other abnormalities. Stressed, untreated mice had elevated levels of PC and TG in the prefrontal cortex, hippocampus, amygdala, and striatum and increased expression of Il-1β, Tnf, c-Fos, Cox-1, and Cox-2. Treatment with thiamine or benfotiamine significantly ameliorated most of these changes in the stressed groups. Thus, thiamine compounds may have therapeutic potential in patients with PTSD, owing to their antioxidant and anti-inflammatory properties. Full article

Background: Autism spectrum disorder (ASD) is associated with social-communication challenges that can hinder timely diagnosis and treatment during acute medical events (AMEs). The purpose of this report is to review the literature on medical comorbidities and AMEs in adults with profound ASD and highlight how healthcare teams can better understand atypical presentations of acute pain and discomfort in adults with profound ASD to reduce delayed diagnoses, delays in treatment, and ultimately improve health outcomes. Methods: The literature on medical comorbidities and AMEs in adults with profound ASD was reviewed using the following databases: PubMed, PsycINFO, and Google Scholar. The histories of three adults with profound ASD who experienced AMEs—specifically, appendicitis, nephrolithiasis, and eosinophilic esophagitis (EoE)—are described. The clinical cases were selected to illustrate the challenges inherent in diagnosing and treating AMEs in adults with profound ASD in the context of the review. Results: In Case 1, a 31-year-old male with autism was diagnosed with perforated appendicitis after his family noticed behavioral changes. In Case 2, a 36-year-old male with autism experienced intermittent pain from nephrolithiasis and communicated his discomfort through irritability and pointing. In Case 3, a 34-year-old male with autism exhibited atypical behavior due to pain from undiagnosed EoE, identified after years of untreated pain and multiple unsuccessful clinical procedures. Conclusions: This review and the illustrative cases demonstrate the significant role that communication barriers play in delayed medical diagnoses for adults with profound ASD during AMEs. Integrating caregiver insights and recognizing atypical pain expressions are essential for improving the accuracy and timeliness of diagnosis and treatment in this population. Full article

The neurobiology of chronic pain is complex and multifaceted, intertwining with the mesocorticolimbic system to regulate the behavioral and perceptional response to adverse stimuli. Specifically, the ventral tegmental area (VTA), the dopaminergic hub of the reward pathways located deep within the midbrain, is crucial for regulating the release of dopamine (DA) throughout the central nervous system (CNS). To better understand the nuances among chronic pain, VTA response, and therapeutics, implementing progressive approaches for mapping and visualizing the deep brain in real time during nociceptive stimulation is crucial. In this study, we utilize a fluorescence imaging platform with a genetically encoded calcium indicator (GCaMP6s) to directly visualize activity in the VTA during acute nociceptive stimulation in both healthy adult mice and adult mice with partial nerve ligation (PNL)-induced neuropathic pain. We also investigate the visualization of the analgesic properties of morphine. Deep brain imaging using our self-fabricated µ-complementary metal–oxide–semiconductor (CMOS) imaging device allows the tracking of the VTA’s response to adverse stimuli. Our findings show that nociceptive stimulation is associated with a reduction in VTA fluorescence activity, supporting the potential of this platform for visualizing pain-related responses in the central nervous system. Additionally, treatment with morphine significantly reduces the neuronal response caused by mechanical stimuli and is observable using the CMOS imaging platform, demonstrating a novel way to potentially assess and treat neuropathic pain.

Background: Endometriosis is a chronic, inflammatory, estrogen-dependent gynecological disease in which endometrial-like tissue grows in areas outside the uterus. This condition may significantly influence women’s life course and mental health. Personal, behavioral, social, and environmental factors play a crucial role in predicting these outcomes. The current study aimed to compare the Perceived Life Course Impact (PLCI) and mental health of women with Endometriosis to those without the disease, as well as to explore the factors associated with PLCI and mental health. Methods: This cross-sectional study surveyed 543 Israeli women (270 with Endometriosis, 273 without). Participants completed a validated questionnaire assessing perceptions of life course impact in several life domains (intimacy and relationships, employment, education) and mental health. Multiple regression analyses were used to identify factors associated with PLCI and mental health among participants. Results: Women with Endometriosis reported a significantly greater negative perceived impact on intimacy and relationships, employment, and education, with poorer mental health, as compared to the control group. Women with Endometriosis also experienced higher social negativity and lower social support. Multiple regression analyses indicated social negativity as a strong predictor of negative PLCI. Additionally, menstrual pain, social support, and healthcare accessibility were found to be significant predictors of both PLCI and mental health. Conclusions: Comprehensive care for women with Endometriosis requires a multidisciplinary approach, with interventions focused on improving healthcare accessibility, enhancing social support networks, and mitigating social negativity within interpersonal environments.

Neuropathic pain is a persistent and exhausting condition which results from damage to the nervous system and is often accompanied by emotional and cognitive impairments. In this study, we investigated dynamic changes in pain-related behaviors over 8 weeks using a spared nerve injury (SNI) model in male C57Bl/6 mice. We examined behavioral outcomes in conjunction with glial activation, neurogenesis, and glutamatergic signaling in the hippocampus to elucidate the mechanisms underlying cognitive and affective alterations associated with chronic pain. Our findings demonstrate that SNI-induced neuropathic pain progressively increases anxiety-like behavior and impairs both working and long-term memory. These behavioral deficits are accompanied by significant activation of microglia and astrocytes, a reduction in hippocampal neurogenesis, and a decrease in the expression of NMDA and AMPA glutamate receptor subunits and the scaffolding protein PSD-95. Taken together, our results suggest that hippocampal neuroinflammation and associated synaptic dysfunction contribute to the affective and cognitive disturbances observed in chronic pain, providing insight into potential molecular targets for therapeutic intervention.

This study aims to explore the associations between menstrual health, lifestyle behaviors, biological traits, and coping strategies among female students at a Vietnamese medical university. A cross-sectional survey was conducted among 884 female students across five academic majors. Data on demographics, menstrual patterns, biological characteristics, lifestyle behaviors, and coping mechanisms were collected. Statistical analyses included descriptive statistics, correlation, and logistic regression to identify significant predictors of self-reported menstrual changes post university admission. Of the 884 participants, 49.8% reported menstrual changes after entering university. Among the lifestyle-related factors, increased daily electronic use (mean = 5.83 h) and later bedtimes (mean = 23:58) were associated with menstrual change (p < 0.01). Older age and higher academic year emerged as significant predictors of menstrual changes (p < 0.001). Additionally, students with blood groups A and B exhibited a higher risk compared to those with group O (p < 0.05), and Rh-positive status was also significantly associated with menstrual changes (p = 0.05). In terms of knowledge and coping practices, students who had premenstrual syndrome awareness since school were significantly less likely to report menstrual changes (p = 0.003). Although use of pain relief, particularly painkillers, correlated with higher reported pain severity, it was not directly linked to menstrual change. On the other hand, clinic consultations were positively associated with menstrual changes (p = 0.003), while students who relied on their mothers as counselors exhibited a protective association (p = 0.001). Menstrual health in university-aged women is influenced by a complex interplay of lifestyle behaviors, biological traits, and menstrual knowledge. Early education and structured coping support may serve as protective factors. The findings call for targeted menstrual health programs in university settings. Full article

Objective: Successful local anesthesia reduces patient pain and anxiety, facilitates the procedure, and enhances overall comfort; however, in children, it may also increase the risk of parafunctional activities in anesthetized areas. This retrospective study aimed to evaluate the factors influencing the risk of self-inflicted injuries. Methods: A study was conducted from January to December 2023 using the records of 4285 pediatric patients aged 4–12 years who underwent dental treatment under local anesthesia. Among 1161 cases at Poznan University (Poland), 73 (6.3%) of self-inflicted injuries were reported. At Rome University (Italy), 823 cases were reviewed, with 522 involving local anesthesia and 23 cases (4.4%) of trauma. Results: The overall prevalence of trauma following local anesthesia was 5.9%, indicating significant clinical concern. The lips were the most commonly affected (69.9%), followed by the cheeks (15.1%) and tongue (15.1%). The study confirmed a positive correlation between younger age and higher trauma incidence, with no significant differences in sex or ethnicity. Longer anesthesia duration and higher anesthetic doses were associated with increased lesion severity. The type of anesthetic also played a role, with articaine showing a higher risk compared to lidocaine. Furthermore, the type of injection influenced trauma incidence, due to the distribution of numbness and exploratory behaviors. Conclusions: Local anesthesia remains an indispensable tool in pain management in pediatric dentistry. However, the risk of self-inflicted injuries is not limited to the youngest patient. Proper education on post-anesthetic care is essential for minimizing complications and ensuring safe and effective dental treatment. Full article

Background: Although COVID-19 vaccination has been effective in reducing severe illness and mortality, its differential clinical behavior in vaccinated and unvaccinated individuals during the early stages of the pandemic—especially in settings with partial coverage and real-world conditions—remains insufficiently characterized. Objective: To assess differences in clinical presentation, comorbidity prevalence, hospitalization, and mortality between vaccinated and unvaccinated patients diagnosed with SARS-CoV-2 during the early phase of the pandemic. Methods: An analytical cross-sectional study was conducted using 4625 electronic medical records of patients diagnosed with COVID-19 in Guerrero, Mexico, between 1 January and 31 December 2021. Variables included vaccination status, age, sex, comorbidities, symptom severity, clinical outcomes, and mortality. Statistical analyses involved chi-square tests, logistic regression for hospitalization probability, and Cox proportional hazards models for mortality risk. Results: Of the patients analyzed, 31.45% had received at least one vaccine dose. Fever, headache, cough, and anosmia were more frequent among vaccinated individuals (p < 0.001). Prostration and chest pain were strongly associated with hospitalization in both groups. In unvaccinated patients, smoking (OR = 4.75), obesity (OR = 3.85), and hypertension (OR = 2.94) increased hospitalization risk. Among vaccinated patients, diabetes mellitus (OR = 3.62) and hypertension (OR = 2.88) were key predictors. Vaccination was significantly associated with lower odds of hospitalization (OR = 0.38; 95% CI: 0.26–0.55) and reduced mortality risk (HR = 0.24; 95% CI: 0.08–0.71). Conclusions: Vaccination status was a significant protective factor for both hospitalization and mortality; however, clinical symptoms and comorbidity-related risks varied, highlighting the need for individualized patient management strategies.

Background/Objectives: Osteoarthritis is a degenerative joint disease that affects people worldwide. It is characterized by joint pain, synovial inflammation, and the degradation of articular cartilage with subchondral bone. Presently, there is no known cure, and pharmacological treatment options are limited. Blueberries contain phytochemicals, which have been linked to positive health benefits and may offer therapeutic benefits. Therefore, the purpose of this study was to examine the dose-dependent effects of whole blueberries on arthritis symptoms in a monosodium iodoacetate (MIA)-induced rat model of osteoarthritis. Methods: Forty female rats were used for this study. Thirty were injected with MIA to induce joint degradation associated with osteoarthritis. Ten served as controls without MIA induction. The MIA-induced rats were randomized into three groups. All groups were fed a casein-based diet, with two of the MIA-induced groups receiving an addition of whole-blueberry powder at 5% and 10%. Fasted blood specimens and tissues of interest were collected post-euthanasia for analysis. Mechanical allodynia and joint widths were assessed throughout this study. Results: MIA induction resulted in changes in pain behaviors and the development of mechanical allodynia. The MIA injection produced inflammation, pain symptoms, and behaviors that are representative of those observed in humans with osteoarthritis. The incorporation of whole blueberries into diets reduced pain behaviors and inflammation. Conclusions: Overall, whole blueberries showed limited, non-dose-dependent effects in the MIA-induced rat model of osteoarthritis. While some outcomes improved in blueberry-treated groups, the overall results were not consistently significant. These preliminary findings suggest potential biological activity and support the further investigation of blueberries’ therapeutic efficacy. Full article

Major Depressive Disorder (MDD) is a chronic mental disorder characterized by anhedonia, loss of desire, guilt, suicidal thoughts, and appetite changes. It is reported that individuals with MDD resort to binge eating to escape from negative feelings. In this study, we aimed to determine the relationship between binge eating behavior and the concept of psychological pain associated with emotions such as shame, guilt, and anger in individuals with MDD. We conducted the study in the Psychiatry Outpatient Clinics of Balcalı Hospital, Çukurova University Faculty of Medicine. The sample consisted of 147 individuals with MDD without psychotic symptoms and 128 healthy controls with sociodemographic characteristics similar to the MDD group. We administered a sociodemographic data form, the Hamilton Depression Rating Scale (HDRS), Psychache Scale (PS), Tolerance for Mental Pain Scale-10 (TMPS-10), Barratt Impulsiveness Scale (BIS-11), and Eating Disorder Examination Questionnaire (EDE-Q-13). Eighty-two (55.7%) of the patients with MDD were diagnosed with binge eating disorder (BED). In the group of MDD patients with BED comorbidity, the EDE-Q-13 total, binging subscale, and HDRS scores were significantly higher than those of the other groups (p < 0.05 for each group), with large to very large effect sizes (e.g., EDE-Q-13 binging d = 1.04; HDRS d = 1.91; PS d = 1.22). There was no significant difference between the MDD groups (with and without BED) regarding the BIS and BIS subscales’ subscores, PS, and TMPS scores. For participants with MDD, there was a significant same-directional correlation between EDE-Q-13 binging, HDRS, BIS, and PS scores (p < 0.05 for each), with moderate to strong effect sizes (EDE-Q-13 binging and HDRS: r = 0.398, p < 0.001; binging and PS: r = 0.273, p < 0.001; binging and BIS: r = 0.233, p = 0.005; binging and TMPS-10: r = –0.257, p = 0.002). Additionally, a negative correlation was observed between TMPS and the scores for EDE-Q-13 binging, HDRS, BIS, and PS. A linear regression analysis indicated that depression severity and BMI were the strongest predictors of binge eating behavior (R² = 0.243; f² = 0.32). Based on our results, we concluded that the presence of binge eating behavior in patients with MDD is associated with more severe depressive symptoms, psychological pain, impulsivity, and lower tolerance to psychological pain. The finding that binge eating behavior was most strongly associated with depression severity and body mass index (BMI) supports the notion that binge eating behavior is a maladaptive attitude. Longitudinal studies comparing individuals with different BMIs in different clinical samples are needed to confirm our results. Full article

Background/Objectives: In 2022, 2.2 million adolescents were diagnosed with substance use disorders, including 265,000 with opioid use disorder. The National Survey on Drug Use and Health revealed that 130,000 adolescents misused prescription pain medications, often obtaining them from friends or relatives. This age group perceives weekly heroin use as less risky than those younger or older. Methods: A questionnaire was developed for 7th to 12th graders in a rural Texas school district as part of a fentanyl awareness curriculum. The questionnaire included Likert scale, multiple choice, and yes/no questions. The participants were categorized into younger (grades 7th and 8th) and older students (grades 9th through 12th), and associations were explored between demographic characteristics, responses, and grade groups using chi-square tests. To assess confidence, behavior, and the impact of education, we used chi-square and Fisher’s exact tests. Results: The participants (n = 94; 85.11%) identified as Hispanic or Latino, with a smaller percentage identifying as White or more than one race. An association was found between feeling more in control of actions related to substances and fentanyl (p-value = 0.04) after receiving education. No association was found between education and confidence in identifying fentanyl. Conclusions: This study aligns with a surge in fentanyl-related overdose deaths in a high-intensity drug trafficking region. Recent fentanyl overdoses among school-age children prompted legislative changes in 2023, making this study valuable for understanding the epidemic within the geographical context. These results suggest that school-based education may play a role in strengthening adolescents’ behavioral intentions to fentanyl exposure, though additional efforts are needed to improve risk identification.

Background/Objective: This cross-sectional study assessed the prevalence of temporomandibular disorders (TMD) among Italian university students and their association with emotional factors and parafunctional behaviors. Methods: A total of 321 students participated in this study. TMD signs and symptoms were evaluated using the DC/TMD criteria through clinical examinations and self-report questionnaires: physical (Symptom Questionnaire), psycho-emotional (PHQ-9, PHQ-15, PHQ-4, and GAD-7), and wake-state oral behaviors (Oral Behavior Checklist, OBC). The Mann–Whitney U test assessed associations between TMD, sociodemographic data, oral behaviors, and psychological vulnerability (p < 0.05). Results: Pain-related symptoms were present in 37% of students (male/female ratio 1:2.7; p < 0.001), and joint dysfunction in 28%, with no gender differences. The median score of PHQ-9 (2.0; interquartile range IQR 5.0), PHQ-15 (2.0; IQR 5.0), PHQ-4 (3.0; IQR 6.0), and GAD-7 (3.00; IQR 6.0) suggested negligible severity of anxious mood, depressed mood, and somatic symptoms among the university students. However, all scores were noticeably higher in students with pain-related TMD compared to pain-free ones (p < 0.05). OBC scores were significantly related to PHQ (p < 0.001), GAD-7 (p < 0.001), and pain symptoms (p < 0.001). Science faculty students (S) showed higher OBC scores than humanities ones (H; S: 20.0; IQR 13.0 vs. H: 16.0; IQR 14.0; p < 0.001), and an H/S ratio of 1:2 was found in pain prevalence (p < 0.05). Conclusions: This study found a high prevalence of TMD signs and symptoms, particularly pain-related, among university students, strongly linked to emotional factors and oral behaviors. Full article
