BACKGROUND This 3-dimensional (3D) optical study aimed to evaluate the effects of microwave glazing on the surface roughness of zirconia-reinforced glass. Glazed surfaces of ceramic provide a smooth and esthetically superior restoration. There are many methods of glazing. However, this study aims to evaluate the effect of microwave glazing on ceramic restorations over conventional oven and hand polishing. MATERIAL AND METHODS A sample size of 90 ceramic material tiles was derived according to the standard sample size formula. The 3 dental ceramics used were IPS e.max CAD (lithium disilicate ceramic; IvoclarVivadent), Suprinity (zirconia-reinforced lithium silicate; VITA Zahnfabrik), and Celtra Duo zirconia-reinforced lithium silicate; Dentsply Sirona). Each group was further divided equally to undergo conventional oven glazing, hand polishing, and microwave glazing. The final glazed surfaces were then evaluated for surface roughness with the Ra parameter, using a Contour GT 3D Optical Microscope (Bruker) and 3D non-contact surface metrology with interferometry. RESULTS The ANOVA test for intergroup comparison showed microwave glazing was a significantly better glazing method than conventional oven and hand polishing (P<0.05). A statistically significant difference was shown between conventional and microwave glazing; however, the difference was greater between conventionally glazed and hand-polished specimens. Furthermore, a highly significant difference between microwave-glazed and hand-polished specimens was observed. CONCLUSIONS Results showed that irrespective of the ceramic, microwave-glazed ceramics were better than traditional oven-glazed ceramics, and hand-polishing resulted in a rougher surface than glazing. Irrespective of the surface treatment methods, IPS e.max CAD ceramic showed a relatively smoother surface than did Suprinity and Celtra Duo.

BACKGROUND The incidence of lung diseases in premature newborns is significantly higher than in full-term newborns due to their underdeveloped lungs. Ultrasound and X-ray are commonly-used bedside examinations in neonatology. This study primarily compares the efficacy of chest X-ray (CXR) and lung ultrasound (LUS) images in evaluating lung consolidation and edema in premature newborns at Neonatal Intensive Care Units (NICU). MATERIAL AND METHODS A retrospective analysis was conducted on LUS and CXR examination results, along with clinical records of premature newborns admitted to our hospital's NICU from November 1, 2019, to December 31, 2021. CXR and LUS scans were performed on the same newborn within a day. We evaluated the consolidations and edema by interpreting the CXR and LUS images, then compared the findings. RESULTS Out of 75 cases, 34 showed lung consolidations on LUS (45%), while only 14 exhibited consolidations on CXR (19%). The detection rate of consolidations by LUS was significantly higher compared to CXR (34/75 vs 14/75, P<0.001). Differences were observed between the 2 bedside examinations in identifying consolidations, with some cases seen only on LUS. CXR struggled to accurately assess the severity of lung edema visible on LUS, showing significant disparity in detecting interstitial edema (53/75 vs 21/75, P<0.001). CONCLUSIONS LUS outperforms chest CXR for bedside assessment of lung consolidation and edema in premature newborns.

This article provides a narrative review of recent developments in mood-stabilizing drugs, considering their mechanism of action, efficacy, safety, and therapeutic potential in the treatment of mood disorders, particularly bipolar disorder and schizophrenia. The review focuses on the mechanism and clinical aspects of second-generation antipsychotic medications; aripiprazole, classified as a third-generation antipsychotic medication; lamotrigine, as a representative of antiepileptic drugs; and lurasidone, a novel second-generation antipsychotic medication. Moreover, the article refers to one of the newest and most highly effective normothymic drugs, cariprazine. The potential of new mood stabilizer candidates lumateperone and brexpiprazole is also presented. Covered topics include the clinical efficacy of new drugs in reducing manic and depressive symptoms during acute episodes, as well as their role in preventing relapse. In addition, we analyzed the incidence of adverse effects of each drug. Many of the new drugs have strong potential to be beneficial and safe in cases of many comorbidities, as they do not cause many adverse effects and do not require high doses of use. The results underscore the importance of ongoing and future research to better understand the action and efficacy of these mood stabilizers and their implications in the treatment of mood disorders, aiming to achieve euthymia and improve the quality of life of affected patients. In this article, we aim to review current drug treatments for the management of mood disorders, including bipolar disorder and schizophrenia.

BACKGROUND Menopausal hormone therapy (MHT) has been receiving increasing attention in developed countries. The purpose of this study was to investigate understanding of menopause and acceptance of MHT in Qinhuangdao, China. MATERIAL AND METHODS We analyzed data from 186 perimenopausal patients on topics including menopausal symptoms and acceptance of and adherence to MHT treatment. We also surveyed 100 medical staff on menopausal-related knowledge. RESULTS Group A consisted of 41 patients treated with MHT for more than 1 cycle, group B consisted of 49 patients who had received MHT but had stopped it for more than 3 months, and group C consisted of 96 patients who never received MHT. There was a significant difference among them in modified Kupermann scores before treatment (P<0.05), but the difference disappeared after MHT (P>0.05). In group C, 32 patients (33%) were unaware of MHT, 60 (62.5%) were worried about the risk of breast/endometrial cancer, 24 (25%) were worried about high costs, and 67 (70%) had no obvious symptoms and did not want MHT. Similarly, in group B, most people stopped MHT for fear of breast or endometrial cancer. A survey targeting 100 medical staff in our hospital found 14 people (14%) knew about and were willing to accept MHT, 44 people (44%) knew about MHT but were afraid to use it, and 42 people (42%) did not know about MHT at all. CONCLUSIONS MHT has not yet been accepted by the majority of people, even medical staff, in Qinhuangdao, China, and much further progress is needed.

BACKGROUND This study aimed to compare the hemodynamic changes and the occurrence of oropharyngeal complications among patients undergoing tracheal intubation with an ordinary laryngoscope, video laryngoscope, and rigid video laryngoscope under general anesthesia. MATERIAL AND METHODS Patients undergoing elective tracheal intubation under general anesthesia were prospectively enrolled as study subjects. Hemodynamic indicators such as diastolic blood pressure (DBP), systolic blood pressure (SBP), mean arterial pressure (MAP), and heart rate (HR), as well as the incidences of oropharyngeal complications, including dental injury, oral mucosal injury, hoarseness, sore throat, and dysphagia, were observed in the patients of 3 groups (group A: ordinary laryngoscope, group B: video laryngoscope, group C: rigid video laryngoscope). Observations were made after anesthesia induction (T₀), immediately after tracheal intubation (T₁), and at 5 min after intubation (T₂). RESULTS The HR at T1 in group A was significantly higher than in groups B and C (P<0.05). However, the difference in the number of tracheal intubations was statistically significant among the 3 groups (P<0.05); group C exhibited the highest first-time success rate of tracheal intubation (95%), whereas group A had the highest failure rate (5%). Significant differences were also noted in the incidences of oral mucosal injury and sore throat among the groups (P<0.05), with the highest incidence in group A and the lowest in group C. CONCLUSIONS Compared with the ordinary laryngoscope, tracheal intubation using a video or rigid video laryngoscope results in milder hemodynamic impacts and fewer intubation-related complications. The rigid video laryngoscope may be safer and more effective.

BACKGROUND The COVID-19 outbreak emerged as a dual threat, effecting both the physical and mental well-being of healthcare staff. This study aimed to evaluate sleep quality using the Pittsburgh Sleep Quality Index (PSQI), levels of anxiety and depression using the Hospital Anxiety Depression Scale (HADS), and the significant influencing factors during COVID-19 pandemic in 284 workers in a medical call center in January 2021. MATERIAL AND METHODS Out of 443 pre-hospital care providers, 284 consented to participate. Data collection was done using an introductory information form, the PSQI for sleep quality, and the HADS for anxiety (HADS-A) and depression (HADS-D). Surveys were hosted on an online survey website and distributed via WhatsApp, with completed forms retrieved from the website. RESULTS Male sex (P=0.0001) and extended working hours in current workplace (P=0.017) were associated with higher HADS-A scores. Health problems, increased need for mental support, and poor job satisfaction correlated with lower HADS-D scores (P=0.025, P=0.005, P=0.0001, respectively) and higher PSQI scores (P=0.008, P=0.009, P=0.008, respectively). A moderately significant positive correlation was found between overall sleep quality and HADS-A (P=0.001, r=0.538) and HADS-D scores (P=0.001, r=0.493). CONCLUSIONS The pandemic significantly impacted the mental health and sleep quality of frontline healthcare personnel, necessitating the identification and mitigation of adverse psychosocial factors. Implementing and evaluating psychoeducational programs and establishing multidisciplinary mental health teams can provide for essential support and counseling, promoting the well-being of healthcare staff and ensuring effective emergency care.

Gastric cancer is a common malignant tumor, and its incidence rate ranks first among malignant tumors of the digestive tract, seriously endangering human physical and mental health. Changes in the physiological state of gastric cancer patients can bring about many physical and psychological symptoms and have a serious impact on their quality of life. Symptom clusters are 2 or more concurrently occurring and interrelated symptoms, with the core symptoms within the cluster remaining stable over time and the symptoms in the cluster being independent of each other. The prerequisite for solving this problem is to screen out appropriate symptom assessment tools according to the clinical situation. The aim of this study was to provide a reference for the development of assessment tools suitable for symptom clusters of gastric cancer patients in China, and to provide evidence for the subsequent optimization of symptom management and some clinical decisions. The contents, application, advantages, and disadvantages of symptom cluster assessment tools for gastric cancer patients in China and abroad were reviewed, and the basic situation and contents of each assessment tool were compared. In China, most of the assessment tools used in domestic gastric cancer research institutes were imported from foreign scales, with a long time span and low specificity for symptoms in various stages of disease development at present. Scholars should be encouraged to develop time-specific assessment tools for the disease characteristics of gastric cancer patients in China, and actively explore the pathogenesis and influencing factors of symptom clusters in this population.

On August 14, 2024, the Director General of the World Health Organization (WHO) declared that the increasing outbreaks of mpox (formerly monkeypox) should be regarded as an international public health emergency due to the growing number of cases in endemic and non-endemic geographical areas, and increasing disease severity. The latest update from the WHO and the alerts given regarding the status of mpox follows an upsurge in the incidence and severity of mpox in the Democratic Republic of the Congo (DRC) and an increasing number of African countries, with spread to other continents and countries This Editorial aims to provide an update on the current status of mpox and includes reasons for the increasing global concerns for the spread of the mpox virus (MPXV).

BACKGROUND An exercise program was developed using risk factors for non-specific neck pain. This study aimed to compare the effects video-based versus image- and text-based remote home training performed using this exercise program in patients with non-specific neck pain. MATERIAL AND METHODS Among the 37 patients with non-specific neck pain recruited, 34 patients who satisfied the inclusion criteria were enrolled in this study. The participants were randomized into the experimental (n=17) and control (n=17) groups. The patients in the experimental group performed exercises using a video-based application system, whereas those in the control group performed exercises using an image- and text-based printout. In-home training was implemented for 6 weeks in both groups. The neck pain intensity, disability index, active range of motion (aROM), forward head posture (FHP), and compensatory neck flexion were measured before and after the intervention. The within-group and between-group differences were analyzed at the end of the interventions. RESULTS Improvements in pain intensity, cervical ROM, disability index, FHP, and compensatory neck flexion were observed after in-home training in the experimental group (P.05). Between-group comparison revealed that the experimental group exhibited greater improvement in pain intensity, cervical ROM, and FHP than the control group (P<.05). CONCLUSIONS The findings of this study suggest that the video-based home exercise program improved pain intensity, aROM, neck disability index, FHP, and compensatory neck flexion in patients with non-specific neck pain.

BACKGROUND The greater palatine foramen (GPF) is anatomically located distal to the third maxillary molar tooth, midway between the midline of the palate and the dental arch. The GPF contains the major palatine artery, vein, and nerve, traversing the palatine sulcus. This study aimed to evaluate the anatomical position of the GPF in 93 women and 67 men at a single center in Cyprus using cone beam computed tomography (CBCT). MATERIAL AND METHODS A retrospective analysis was conducted on 160 CBCT scans. Measurements of the GPF's horizontal and vertical diameters, distances from GPF to the incisive foramen, posterior nasal spine, anterior nasal spine, and midaxillary suture, and positional relationships to molars were recorded. Statistical analyses compared these measurements between males and females. RESULTS The study included 93 females and 67 males with an average age of 46.6 (±11.6) years. Significant sex differences were observed in most GPF measurements, with males showing larger dimensions such as the anterior nasal spine, posterior nasal spine, mid-maxillary suture, and incisive foramen to the GPF. The GPF was predominantly located in the third molar region (96.25% on the right, 96.9% on the left). The left GPF showed a significantly larger horizontal diameter than the right (P<0.05). CONCLUSIONS There was a significant difference in the average distances from the anterior nasal spine, posterior nasal spine, mid-maxillary suture, and incisive foramen to the GPF, as well as in the size of the GPF, between males and females. Recognizing these variations enhances clinical planning and reduces the risk of complications.
