ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has been ongoing since 2020. This period is characterized by a significant change in people’s lifestyles. Children are a particularly affected group. In order to determine the impact of the pandemic on children’s lives, scientific publications available in PubMed, Google Scholar, and The United Nations Children’s Fund (UNICEF) Innocenti’s Children and COVID-19 Library were reviewed, and the statistical data made available by the Polish Ministry of Health on incidence, death and vaccination rates was analyzed. Even if children were not infected with the virus, they felt the effects of the pandemic through restrictions in the daily functioning of schools, service facilities and households. Despite the relatively mild symptoms accompanying infections in pediatric patients, as well as the low rates of hospitalization and mortality, the pandemic have had numerous negative effects on children’s mental and physical health that may trigger further “non-communicable epidemics”. Weight changes, limitations in physical activity, and the intensification of social and emotional problems will certainly have a negative impact on their future lives. The introduction of vaccination for children over the age of 5 brought hope, but since then, it has been accompanied by controversy and uncertainty. Further research is necessary to determine the impact of the COVID-19 pandemic on children.

ABSTRACT

BACKGROUND: Laser protocols for the treatment of dentin hypersensitivity (DH) have not yet been studied systematically.

OBJECTIVES: The present study aimed to review clinical trials on the treatment of DH with laser therapy through a systematic review and meta-analysis.

MATERIAL AND METHODS: The search of electronic databases resulted in 562 publications up to April 2020. The inclusion criteria were studies carried out on humans and reporting on the treatment of DH with laser therapy. Case reports, literature reviews and systematic reviews were excluded. Selected by abstract, potentially eligible papers were read in full (n = 160). Independent examiners performed data extraction and the assessment of the risk of bias.

RESULTS: A total of 34 studies were included in the analysis, and 11 in the quantitative analysis. It was observed that most studies followed up patients for a maximum of 6 months (55%). Through the meta-analysis, we observed statistically significant differences between the average pain before and after 3 months of treatment with highand low-power lasers. However, through indirect comparisons, it was observed that the high-power laser showed a greater tendency to reduce the pain levels after 3 months of treatment as compared to the low-power laser, but without a statistically significant difference.

CONCLUSIONS: It was possible to conclude that regardless of the type of laser used in the treatment of DH, this treatment is an effective option for the control of pain symptoms. However, it was not possible to establish a defined treatment protocol, since the evaluation methods are very different from each other. Text for Rewiew and clinical cases.

ABSTRACT

BACKGROUND: Cone-beam computed tomography (CBCT) is used to provide multiplanar views of the temporomandibular joint (TMJ) bone components as well as TMJ pathologies without superposition, magnification or distortion.

OBJECTIVES: The study aimed to analyze degenerative changes in the condylar surface, and their relationship with patient age and gender, and the TMJ space measurements by using CBCT images.

MATERIAL AND METHODS: A total of 258 individuals were retrospectively analyzed. The degenerative bone changes of the condylar head were evaluated and classified on the right and left sides. The shortest distances from the anterior, superior and posterior parts of the condylar head to the glenoid fossa were measured to represent the TMJ space. Univariate and multivariate logistic regression analyses then evaluated the effect of age and gender on the presence of degenerative changes.

RESULTS: Condylar flattening was most frequently observed (413 TMJs, 53.5%). However, the presence or absence of the change types did not differ according to the sides. The mean values of the TMJ space measurements on the right and left sides were narrower in the group with changes than in the group without changes. Nonetheless, no statistically significant difference in the TMJ space was found between the groups (p > 0.05).

CONCLUSIONS: An increased risk of radiographically detectable degenerative alterations in left TMJs was detected for males and for increasing age. Degenerative changes in the condylar surface may affect the dimensions of the TMJ space.

ABSTRACT

BACKGROUND: Normal airways are a key factor during the craniofacial growth of the young. Therefore, sleep-disordered breathing (SDB) without treatment can have harmful consequences for development and health.

OBJECTIVES: This study aimed to evaluate the cephalometric characteristics in non-snoring individuals and snoring subjects, and investigate differences in the pharyngeal airway space between the 2 groups.

MATERIAL AND METHODS: This case-control study included 70 patients aged over 18 years, selected from a radiology center. The patients were divided into 2 groups: case (35 patients with a history of habitual snoring); and control (35 healthy patients). The Berlin sleep questionnaire was administered to the parents of the patients. The nasopharyngeal airway was measured according to the analysis of Linder-Aronson (1970), and 4 indices were measured and analyzed in each of the lateral cephalometric radiographs.

RESULTS: No statistically significant differences were observed in the pharyngeal measurements between the 2 groups, although all means in the control group were higher than in the experimental group. However, there was a significant relationship between gender and the Ba-S-PNS and PNS-AD2 indices.

CONCLUSIONS: Although the patients with nocturnal snoring had smaller airway dimensions, their pharyngeal measurements were not significantly different from the control group.

ABSTRACT

BACKGROUND: Rheumatoid arthritis (RA) and periodontitis (PD) are chronic diseases that are associated with connective tissue and bone destruction, which affects the quality of life of the people suffering from these conditions. The identification of social conditions and the determinants of RA and PD would permit the elaboration of policies and strategies based on social reality.

OBJECTIVES: The aim of the present study was to identify the relationship between oral health-related quality of life (OHRQoL) and the indicators of general health and oral health in patients with RA.

MATERIAL AND METHODS: A cross-sectional study involving 59 patients with RA was conducted between 2019 and 2020. Demographic, general health, periodontal, and oral health parameters were collected. In addition, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was administered to each patient. A description of the OHIP-14 dimensions according to different variables was performed. The relationship between OHRQoL and general/oral health indicators was analyzed with logistic and linear regression analyses.

RESULTS: The highest OHIP-14 scores were found in people that were 60 years of age and over, single, had low educational achievements, a low socioeconomic status, were unemployed, and had no health affiliation. In the adjusted model, the prevalence of the impact on OHRQoL was 1.34 (1.10-5.29) times greater in those with erosive RA than in those without, and 2.22 (1.16-29.50) times greater in those who self-reported morning stiffness. Regarding the stage of PD, those with stage IV had a prevalence of the impact on the OHRQoL of 70%, an average extent of 3.4 ±4.5 and a severity score of 11.5 ±22.0, with statistically significant differences.

CONCLUSIONS: The dimensions with the greatest impact on the OHRQoL of patients were physical pain, discomfort and psychological disability. The type of RA and the severity of PD are indicators of worse scores on the OHRQoL scale.

ABSTRACT

BACKGROUND: Sjögren’s syndrome (SS) is a common systemic autoimmune disease that affects oral health, and consequently oral health-related quality of life (OHRQoL) due to the involvement of exocrine glands.

OBJECTIVES: The present study aimed to evaluate the oral health-related quality of life and oral health indicators in patients with SS in comparison with healthy individuals.

MATERIAL AND METHODS: In the case and control groups (45 patients and 45 healthy individuals), questions about demographic data, other systemic disorders, medications, the years of infection, xerostomia, as well as inquiries about the quality of life (Oral Health Impact Profile-14 – OHIP-14) were asked. The patients were evaluated clinically, and oral health indicators, including the plaque index (PI), the gingival index (GI), the sulcus bleeding index (SBI), and the number of decayed, missing and filled teeth (DMFT) were assessed on the Ramfjord teeth. Unstimulated saliva samples from both groups were obtained and weighed. The data was analyzed using IBM SPSS Statistics for Windows, v. 24.0. Quantitative variables were compared between the case and control groups with the use of the independent t test or their nonparametric equivalent (the Mann-Whitney test).

RESULTS: The comparison of the quantitative variables between the study groups showed a statistically significant difference in the OHRQoL scores (p = 0.037) and the unstimulated saliva flow rate (p = 0.002) between the case and control groups. Also, there was a statistically significant difference in the DMFT index between patients with primary and secondary SS in the case group (p = 0.048).

CONCLUSIONS: The lower OHRQoL of patients with SS requires more attention and follow-up to solve periodontal and dental problems in this group of patients.

ABSTRACT

OBJECTIVE: Mindfulness-Based Stress Reduction (MBSR) therapy has been very effective intervention across worldwide. Herein we aimed to investigate the effect of MBSR intervention on anxiety, depression among breast cancer patients undergoing postoperative chemotherapy.

METHODS: 225 breast cancer patients in our hospital were divided into two groups, 106 patients in the MBSR group received Mindfulness-Based Stress Reduction intervention, while 111 patients in the control group were given routine nursing. The Self-rating Anxiety Scale (SAS), self-rating depression scale (SDS), and functional assessment of cancer therapy-breast cancer (FACT-B) were used to assess the effect of MBSR intervention on breast cancer patients undergoing postoperative chemotherapy.

RESULTS: There were significant differences in the scores of physiological statuses, social and family status, emotional status, functional status, additional attention and total score after intervention between two groups (P < .05). The difference between SDS and SAS were statistically significant between the two groups (P < .05). The score of SDS and SAS were significantly improved in the MBSR group compared with the control group (P < .05).

CONCLUSION: MBSR therapy could effectively improve the quality of life of patients with breast cancer patients with chemotherapy, mainly focusing on psychological aspects, while the effect of the physiological intervention was not significant.

ABSTRACT

OBJECTIVE: This study investigated the effects of prenatal yoga on labor pain.

METHODS: A systematic review of articles on prenatal yoga for childbirth pain was conducted, and relevant pain score results data were collected for the meta-analysis. The intervention group was treated with yoga movement, and the control group, with routine prenatal examination. All randomized controlled trials were included, but pregnancies with internal complications were excluded.

RESULTS: A total of 47 references were obtained from PubMed, Embase, the Cochrane database, and ClinicalTrials.gov. After applying the exclusion criteria, five studies were included for the review and meta-analysis. A total of 581 women were enrolled. The SMD value summarized for the four studies was -1.05, and the 95% confidence interval was -1.45 to -0.65, which was statistically significant (z = 5.15; P < .01), suggesting that yoga can significantly reduce labor pain.

CONCLUSIONS: Prenatal yoga can relieve labor pain and is recommended for pregnant women.

ABSTRACT

Diabetic nephropathy (DN) is the most important cause of chronic renal and end-stage kidney disease in China. Hypertension (HTN) is highly prevalent in individuals with diabetic nephropathy. Arterial HTN affects two-thirds of people with type 2 diabetes (T2D). In these patients, HTN increased the potential of both micro- and macrovascular complications, and the co-occurrence of 2 such principal causes results in a 4-fold increased risk for cardiovascular disease (CVD) when contrasted with normotensive controls without diabetes. Therefore, the results of valsartan and amlodipine tablets combined with alpha-lipoic acid on total antioxidant capacity (T-AOC) need to be investigated. The aim of this study was to analyze the effects of valsartan (VA) and amlodipine tablets combined with alpha-lipoic acid (α-LA) on T-AOC, IL-6 and β2-MG levels in patients with DN. We performed statistical analysis including the chi-square test, independent t-test, paired t-test and Analysis of Variance (ANOVA). Our findings indicate that VA, amlodipine and α-LA has a significant effect in patients with DN.

ABSTRACT

The purpose of measurement-based care (MBC) is to detect treatment nonresponse sufficiently early in treatment to adjust treatment plans and prevent failure or dropout. Thus, the potential of MBC is to provide the infrastructure for a flexible, patient-centered approach to evidence-based care. However, MBC is underutilized across the Department of Veterans Affairs (VA) posttraumatic stress disorder (PTSD) specialty clinics, likely because no actionable, empirically determined guidelines for using repeated measurement effectively are currently available to clinicians. With data collected as part of routine care in VA PTSD specialty clinics across the United States in the year prior to COVID-19 (n = 2,182), we conducted a proof-of-concept for a method of generating session-by-session benchmarks of probable patient nonresponse to treatment, which can be visualized alongside individual patient data using the most common measure of PTSD symptoms used in VA specialty clinics, the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (PCL-5). Using survival analysis, we first identified the probability of cases reaching clinically significant change at each session, as well as any significant moderators of treatment response. We then generated a multilevel model with initial symptom burden predicting the trajectory of PCL-5 scores across sessions. Finally, we determined the slowest changing 50% and 60% of all cases to generate benchmarks at each session for each level of the predictor(s) and then assessed the accuracy of these benchmarks at each session for classifying treatment responders and nonresponders. The final models were able to accurately identify nonresponders as early as the sixth session of treatment. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
