ABSTRACT

INTRODUCTION: Developments in dental materials, CAD/CAM technologies and adhesive dentistry have improved the application of conservative restorations such as endocrowns and onlays. Among ceramics, zirconia has properties such as high strength, transformation toughening, chemical and structural durability, and biocompatibility, which enable zirconia to be used in the posterior area.

AIM: This study is a comparative evaluation of fracture resistance and failure modes in endodontically treated molars restored with zirconia endocrown and onlays.

MATERIALS AND METHODS: This study was performed on 20 human mandibular first molars with similar dimensions. After root canal treatment, the samples were divided into two groups: endocrowns and onlays (n=10). Restorations were made using a CAD-CAM milling machine with zirconia CAD blocks and, after cementation, subjected to 10,000 thermocycling and 500,000 fatigue cycle procedures, respectively. Each specimen was placed on a Universal Testing Machine and subjected to axial compressive force applied at a crosshead speed of 0.5 mm/min. The mean loads of failure of each group were statistically compared using the Student t-test. Chi-square tests were used to compare frequencies of failure modes among groups.

RESULTS: Fracture resistance showed a statistically significant difference between endocrown (5374.6810±670.03445 N) and onlay (3312.5000±804.01428 N) (p<0.001). No statistically significant difference was detected in the distribution of failure types among the groups (p>0.05).

CONCLUSIONS: The fracture resistance of endocrown is substantially higher than that of onlay, and failure type does not differ in both restorations. Zirconia is a reliable material to use in conservative restorations.

ABSTRACT

INTRODUCTION: Masticatory pressure increases in the distal areas of the dentition. This should be considered when restoring partially edentulous patients with a metal-free fixed partial denture (FPD). An alternative abutment preparation design can be used in order to increase the materials’ volume in the most fracture-prone “connector area” of an FPD. The increased size of the connection might positively influence the constructions’ mechanical durability, thereby increasing its success and survivability.

AIM: The aim of the present study was to investigate the influence of two preparation designs of the distal abutment on the fracture resistance of three-unit, monolithic, ZrO2 FPDs.

MATERIALS AND METHODS: 3D printed replicas of a partially edentulous mandibular segment and a ZrO2, milled in full-contour, three-unit FPDs were used for this investigation. Two experimental groups (n=10 ) were defined based on the preparation design of the distal abutment tooth – classical shoulder preparation 0.8 mm deep, and endocrown preparation with a 2-mm retention cavity. The bridge – mandibular segment replica assembly was done with relyXU200(3M ESPE, USA), light-cured for 10 seconds per side with D-light Duo (GC, Europe). After cementation the test specimens were subjected to loading in a universal testing machine Zwick (Zwick-Roell Group, Germany). Statistical analysis was performed using R and includes descriptive statistics, t-test for quantitative and chi-squared test for qualitative variables.

RESULTS: The results showed no difference between the two studied groups in the maximum force required to fracture the test specimens [t=-1.8088 (17.39), p-value=0.087; P>0.05]. 95% of the fracture lines were located in the distal connector.

CONCLUSIONS: Within the limitations of this study, it can be concluded that both tested preparation designs show similar results in terms of the load required to fracture the test specimens. Furthermore, it is confirmed that the distal connector is the weakest area of an all-ceramic 3-unit FPD in the posterior area.

ABSTRACT

INTRODUCTION: Good medical care depends both on the access to specialists and awareness of patients and healthcare professionals.

AIM: The purpose of this study was to assess the accessibility to rheumatology outpatient care and the awareness of patients with inflammatory joint diseases with regard to the types of sources and preferences of sources for obtaining information related to their disease and treatment, as well as to establish the extent to which this information is useful to patients.

MATERIALS AND METHODS: A pilot, cross-sectional, single center, anonymous study was conducted among adult patients with inflammatory joint diseases who were monitored in an outpatient rheumatology room at St George Diagnostic and Consultative Center in Plovdiv. A total of 56 patients were monitored. The questionnaire contained 56 questions, divided into 5 main groups: 1. questions about the disease, 2. questions about the sociodemographic profile of the patients, 3. questions about accessibility to specialized healthcare, 4. questions about the role of the nurse in the training of patients with inflammatory joint disease, and 5. questions evaluating the attitude to the monitoring medical team. The data were analyzed with IBM SPSS V.26, at a statistical significance level of p<0.05 for all analyses.

RESULTS: Women predominated among the patients under observation (37, 66%), as well as patients in the age group of 50-79 years (46, 82%). Twenty-four (42.9%) were the patients attending the consulting room twice a year. On-the-spot booking in the consulting room was preferred mainly among patients who lived within 50 km (3/16, 19%), while the rest of the patients preferred booking appointments by phone. Forty-five (80%) patients of the total number of patients used subcutaneous biological agents. Among them, the patients whose first application was performed by a nurse in a rheumatology room predominated (44 patients, 96%). All respondents (56, 100%) indicated that they had received self-injection training from a healthcare professional.

CONCLUSION: Patients with inflammatory joint diseases need information to help them manage issues related to their disease and treatment, as well as cope with their physical and psychological needs. Our study shows that patients most commonly use a combination of information sources – they get information from a doctor or from a healthcare professional, i.e. a nurse. We highlighted in the study the crucial role of nurses in improving the access of patients to specialized rheumatology care and satisfying patients’ information needs.

ABSTRACT

BACKGROUND: Reduced physical activity and having a migration background are both associated with higher loneliness; however, the moderating role of migration background in the association between loneliness and physical activity remains largely unknown.

METHODS: We used cross-sectional data from the sixth wave (year 2017) of the German Ageing Survey (DEAS). Loneliness was measured using the De Jong Gierveld tool and physical activity was dichotomised into either of the following (i.e., at least 150 min of moderate physical activity per week) or not following physical activity recommendations of the World Health Organization (WHO). For evaluation of the associations we applied adjusted linear regression models with robust standard errors.

RESULTS: We included 6257 (average age = 67 years, 50% female) and 285 (average age = 63 years, 51% female) participants without and with migration background, respectively. In multiple linear regressions both migration background (ß = 0.13, P = 0.001), as well as not following the WHO physical activity recommendations (ß = 0.06, P < 0.001) were associated with increased loneliness. Moreover, the respective interaction term reached statistical significance (ß = -0.27, P = 0.013). Participants with migration background have a more pronounced association between following the WHO physical activity recommendations and reduced loneliness compared to participants without migration background.

CONCLUSION: Among middle-aged and older individuals, those with migration background benefit to a larger extent from following physical activity recommendations than the population without migration background regarding loneliness. Thus, motivating individuals with migration background to follow the WHO physical activity guidelines could particularly assist in reducing loneliness.

ABSTRACT

In this study, we evaluated the effects of the pandemic on our trauma population. We performed a retrospective review of the trauma registry in the 2 years prior, and then 2 years during the pandemic. We evaluated age, race, gender, injury severity score (ISS), mechanism of trauma, rate of self-inflicted injury, rate of gunshot wounds (GSW), presence of EtOH, drug screen results, mortality, rate of burn traumas, and zip code of residence. Our query captured 5 054 patients before, and 5 731 during the pandemic. We found no statistical difference in age, gender, mechanism of trauma, rate of self-inflicted injuries, and mortality during the pandemic when compared to before. There were statistically significant differences in race, ISS, rate of GSWs, EtOH use, drug screen results, and burn traumas. Geospatial mapping found a rise in GSWs for zip code 36606. Gun violence and substance use rose in our trauma population during COVID-19.

ABSTRACT

OBJECTIVE: Carbon monoxide poisoning is an important cause of morbidity and mortality all over the world. In our study, it was aimed to determine the clinical and laboratory parameters that may be effective in deciding the need for hyperbaric oxygen therapy in the management of cases.

MATERIALS AND METHODS: From January 2012 to the end of December 2019, 83 patients who applied to a university hospital pediatric emergency department in İstanbul with the diagnosis of carbon monoxide poisoning were included. Demographic characteristics, carbon monoxide source, exposure duration, treatment approach, physical examination findings, Glasgow Coma Score, laboratory results, electrocardiogram, cranial imaging, and chest x-ray were evaluated from the records.

RESULTS: The median age of the patients was 56 (37.0-100.0) months and 48 (57.8%) of them were male. The median time of exposure to carbon monoxide was 5.0 (0.5-3.0) hours in those who received hyperbaric oxygen therapy and was significantly higher than those who received normobaric oxygen therapy (P < .001). Myocardial ischemia, chest pain, pulmonary edema, and renal failure were not detected in any of the cases. The median lactate level was detected as 1.5 (1.0-2.15) mmol/L in those who received normobaric oxygen therapy and 3.7 (3.17-4.62) mmol/L in those who received hyperbaric oxygen therapy, and the difference between them was statistically significant (P < .001).

CONCLUSIONS: A guideline containing precise clinical and laboratory parameters for hyperbaric oxygen therapy in children has not been developed yet. In our study, carbon monoxide exposure duration, carboxyhemoglobin levels, neurological symptoms, and lactate levels were found to be guiding parameters in determining the need for hyperbaric oxygen therapy.

ABSTRACT

OBJECTIVE: To determine changes caused by the effect of the COVID-19 pandemic by examining the children admitted to our hospital because of poisoning during the pandemic and comparing these with data from a study conducted in the pre-pandemic period.

MATERIALS AND METHODS: A retrospective examination was made of children who were admitted to our pediatric emergency department with poisoning between March 2020 and March 2022.

RESULTS: Of the 82 (0.7%) patients admitted to the emergency department, 42 (51.2%) were girls, the mean age was 6.43 ± 5.62 years, and the majority of children (59.8%) were under 5 years of age. The poisonings were determined to be accidental in 85.4% of cases, 13.4% were suicide attempts, and 1.2% were iatrogenic. Poisonings occurred most frequently (97.6%) at home and most frequently (85.4%) by digestive tract. The most common causative agent (68%) was non-pharmacological agents. Caustic-corrosive substances were determined in 39% of cases, medical drugs in 32%, toxic gases in 11%, alcohol (hand sanitizers) in 8.5%, insecticide-pesticide in 6.1%, food in 1.2%, and animal bites in 1.2%. Compared to the study conducted in our hospital in 2013-2014, the difference in terms of factors causing poisoning was statistically significant (P < .001). Of the current study cases, 14 (17.1%) were followed up in the intensive care unit, and no mortality developed.

CONCLUSIONS: The period of the COVID-19 pandemic was seen to cause an increase in poisoning rates with caustic-corrosive substances, alcohol (hand disinfectants), and toxic gases. Families should be made aware of this issue and take special precautions.

ABSTRACT

BACKGROUND: Behaviour change counselling (BCC) is an adaptation of motivational interviewing (MI) designed to maximize the effectiveness of time-limited health behaviour change consultations. To improve intervention quality and understanding of treatment effects, it is recommended that evaluations of health behaviour change interventions incorporate existing fidelity frameworks (e.g. The National Institutes of Health [NIH] Behaviour Change Consortium) and ensure that treatment fidelity is assessed and reported.

PURPOSE: This systematic review was designed to examine (a) adherence to NIH fidelity recommendations, (b) provider fidelity to BCC and (c) impact of these variables on the real-world effectiveness of BCC for adult health behaviours and outcomes.

METHODS AND RESULTS: Searches of 10 electronic databases yielded 110 eligible publications describing 58 unique studies examining BCC delivered within real-world healthcare settings by existing providers. Mean study adherence to NIH fidelity recommendations was 63.31% (Range 26.83%-96.23%). Pooled effect size (Hedges g) for short-term and long-term outcomes was .19 (95% CI [.11, .27]) and .09 (95% CI [.04, .13]), respectively. In separate, random-effects meta-regressions, neither short-term nor long-term effect sizes were significantly modified by adherence to NIH fidelity recommendations. For the subgroup of short-term alcohol studies (n = 10), a significant inverse relationship was detected (Coefficient = -.0114, 95% CI [-.0187, -.0041], p = .0021). Inadequate and inconsistent reporting within the included studies precluded planned meta-regression between provider fidelity and BCC effect size.

CONCLUSIONS: Further evidence is needed to clarify whether adherence to fidelity recommendations modifies intervention effects. Efforts to promote transparent consideration, evaluation and reporting of fidelity are urgently needed. Research and clinical implications are discussed.

ABSTRACT

In 2021, a total of 151 pregnant women were selected from the suburb of Shanghai. A questionnaire survey was conducted to obtain data about maternal age, gestational week, total annual household income, education level and passive smoking among pregnant women and one spot urine was collected. The concentrations of eight neonicotinoid pesticides and four metabolites in urine were measured by ultra-high performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry. The differences in detection frequencies and concentrations of neonicotinoid pesticides and their metabolites among pregnant women with different characteristics were compared, and the influencing factors of the detection of neonicotinoid pesticides in urine were analyzed. The results showed that at least one neonicotinoid pesticide was detected in 93.4% (141 samples) of urine samples. The detection frequencies of N-desmethyl-acetamiprid, clothianidin, thiamethoxam, and N-desmethyl-clothianidin were high, about 78.1% (118 samples), 75.5% (114 samples), 68.9% (104 samples), and 44.4% (67 samples), respectively. The median concentration of the sum of all neonicotinoid pesticides was 2.66 μg/g. N-desmethyl-acetamiprid had the highest detection concentration with a median concentration of 1.04 μg/g. A lower urinary detection frequency of imidacloprid and its metabolites was seen in pregnant women aged 30-44 years [OR (95%CI): 0.23 (0.07-0.77)]. A higher detection frequency of clothianidin and its metabolites was seen in pregnant women with per capita annual household income≥100, 000 yuan [OR (95%CI): 6.15 (1.56-24.28)]. There was widespread exposure to neonicotinoid pesticides and their metabolites in pregnant women from the suburb of Shanghai, which might pose potential health risks to pregnant women, and maternal age and household income were potential influencing factors of the exposure to neonicotinoid pesticides.

ABSTRACT

OBJECTIVE: To investigate the tobacco-attributable burden on disease, medical costs, productivity losses and informal caregiving; and to estimate the health and economic gains that can be achieved if the main tobacco control measures (raising taxes on tobacco, plain packaging, advertising bans and smoke-free environments) are fully implemented in eight countries that encompass 80% of the Latin American population.

DESIGN: Markov probabilistic microsimulation economic model of the natural history, costs and quality of life associated with the main tobacco-related diseases. Model inputs and data on labour productivity, informal caregivers’ burden and interventions’ effectiveness were obtained through literature review, surveys, civil registrations, vital statistics and hospital databases. Epidemiological and economic data from January to October 2020 were used to populate the model.

FINDINGS: In these eight countries, smoking is responsible each year for 351 000 deaths, 2.25 million disease events, 12.2 million healthy years of life lost, US$22.8 billion in direct medical costs, US$16.2 billion in lost productivity and US$10.8 billion in caregiver costs. These economic losses represent 1.4% of countries’ aggregated gross domestic products. The full implementation and enforcement of the four strategies: taxes, plain packaging, advertising bans and smoke-free environments would avert 271 000, 78 000, 71 000 and 39 000 deaths, respectively, in the next 10 years, and result in US$63.8, US$12.3, US$11.4 and US$5.7 billions in economic gains, respectively, on top of the benefits being achieved today by the current level of implementation of these measures.

CONCLUSIONS: Smoking represents a substantial burden in Latin America. The full implementation of tobacco control measures could successfully avert deaths and disability, reduce healthcare spending and caregiver and productivity losses, likely resulting in large net economic benefits.
