ABSTRACT

BACKGROUND: Climate changes associated to global warming are increasingly affecting the quality of cultivated crops. Cultivation at different altitudes and similar latitudes may offer an extraordinarily useful opportunity to trigger changes in climate variables and to further investigate their effect on crop quality. This study evaluated the effect of climatic indices, calculated using temperature, rainfall precipitation and solar radiation data, on commercial parameters and volatile organic compounds (VOCs) profile of wheat at harvest.

RESULTS: Three common and durum wheat varieties, including two heritage wheat, were sown in experimental fields sited at three altitudes for three consecutive years and analysed for their yield, grading parameters and VOCs profiles. The datasets were processed by partial least square regression (PLS-R) and the results indicate that summer days (SU25) and diurnal temperature range (ΔT) are the climatic indices mainly responsible for VOCs profile changes in both common and durum wheat. Accumulated growth degree days (GDD), consecutive dry days (CDD) and accumulated solar radiation (ASR) induced species-specific responses. Terpenes represented the chemical class of VOCs most affected by stresses followed by ketones, and alcohols, which were affected by CDD, GDD and ASR.

CONSLUSION: This study showed a selective response of wheat to abiotic stresses associated with climate variables in terms of VOCs synthesis. The findings reported may be of relevance in several fields, from plant ecology to agronomy and food quality with final implication in local economy strategies.

ABSTRACT

OBJECTIVES: To investigate the distribution characteristics and correlation of intestinal and pharyngeal microbiota in early neonates.

METHODS: Full-term healthy neonates who were born in Shanghai Pudong New Area Maternal and Child Health Hospital from September 2021 to January 2022 and were given mixed feeding were enrolled. The 16S rRNA sequencing technique was used to analyze the stool and pharyngeal swab samples collected on the day of birth and days 5-7 after birth, and the composition and function of intestinal and pharyngeal microbiota were analyzed and compared.

RESULTS: The diversity analysis showed that the diversity of pharyngeal microbiota was higher than that of intestinal microbiota in early neonates, but the difference was not statistically significant (P>0.05). On the day of birth, the relative abundance of Proteobacteria in the intestine was significantly higher than that in the pharynx (P<0.05). On days 5-7 after birth, the relative abundance of Actinobacteria and Proteobacteria in the intestine was significantly higher than that in the pharynx (P<0.05), and the relative abundance of Firmicutes in the intestine was significantly lower than that in the pharynx (P<0.05). At the genus level, there was no significant difference in the composition of dominant bacteria between the intestine and the pharynx on the day of birth (P>0.05), while on days 5-7 after birth, there were significant differences in the symbiotic bacteria of Streptococcus, Staphylococcus, Rothia, Bifidobacterium, and Escherichia–Shigella between the intestine and the pharynx (P<0.05). The analysis based on the database of Clusters of Orthologous Groups of proteins showed that pharyngeal microbiota was more concentrated on chromatin structure and dynamics and cytoskeleton, while intestinal microbiota was more abundant in RNA processing and modification, energy production and conversion, amino acid transport and metabolism, carbohydrate transport and metabolism, coenzyme transport and metabolism, and others (P<0.05). The Kyoto Encyclopedia of Genes and Genomes analysis showed that compared with pharyngeal microbiota, intestinal microbiota was more predictive of cell motility, cellular processes and signal transduction, endocrine system, excretory system, immune system, metabolic diseases, nervous system, and transcription parameters (P<0.05).

CONCLUSIONS: The composition and diversity of intestinal and pharyngeal microbiota of neonates are not significantly different at birth. The microbiota of these two ecological niches begin to differentiate and gradually exhibit distinct functions over time.

ABSTRACT

OBJECTIVES: Upper reference limits of high-sensitivity cardiac troponin T (hs-cTnT) are derived from healthy, population-based cohorts, and are frequently exceeded in hospitalized patients. In this study we aim to systematically examine the differences between in-hospital patients with no diagnosed cardiac diseases and a population-based cohort.

METHODS: Retrospective analyses were performed in two independent cohorts. We included 5,652 participants of the prospective population-based LIFE cohort as well as 9,300 patients having been treated at our hospital between 2014 and 2021. In both cohorts, subjects with diagnosed or suspected cardiac diseases were excluded. We used Spearman’s rank correlation for correlation analyses of hs-cTnT serum concentrations and age. Sex- and age-adjusted 99th percentiles for hs-cTnT in subjects with preserved renal function were obtained in both cohorts.

RESULTS: In both cohorts, hs-cTnT serum concentrations positively correlated with age. Male sex was associated with higher hs-cTnT serum concentrations. Persons treated in hospital showed significantly higher hs-cTnT concentrations in females and males aged above 50. While in the population-based cohort only 99th percentile hs-cTnT results of females aged above 70 and males aged above 60 years exceeded the assay’s upper reference limit, the 99th percentiles of in-hospital females over 40 years and males of all age groups exceeded this threshold.

CONCLUSIONS: Besides age and sex, hospitalization per se is correlated with higher serum concentrations of hs-cTnT in most age groups. Our results indicate, that unconditionally applying current hs-cTnT cut-offs to inpatients might overestimate myocardial infarction and potentially lead to overdiagnosis.

ABSTRACT

OBJECTIVE: This study sought to assess the prevalence and identify factors associated with depression among patients with cardiovascular diseases and followed-up in a public teaching hospital.

METHODS: A cross-sectional study was conducted with a systematic random sample of 302 out-patients with cardiovascular diseases and followed-up in the cardiology outpatient department at Tripoli University Hospital. Stable adults (>18 years of age) were eligible to be included in this study. Face-to-face interviews were conducted to complete a questionnaire comprising questions on demographic, medical, and lifestyle issues besides the Patient Health Questionnaire-9 tool. Statistical Package for the Social Sciences, Version 22, was used to analyze the data.

RESULTS: Age ranged between 29 and 84 years with a mean age of 60.6 ± 10.4 years; 60.6% were females and 75.8% were married. The highest prevalent morbidity was hypertension (76.2%) followed by diabetes mellitus (48%), ischemic heart disease (39%), and different types of arrhythmias (22.8%). About 59.3% of screened patients had different degrees of depression from mild to severe. The participants with a positive history of psychological problems, those complicated with cardiomyopathy, those who were females, patients with a history of cerebrovascular accident, and patients who were living alone were more likely to be depressed.

CONCLUSION: Prevalence of depression is found to be higher among patients with cardiovascular diseases and a family history of psychological illnesses, and cardiomyopathy had the highest contribution as independent predictor for depression. Screening of all patients with cardiovas-cular diseases is essential to identify and treat the patients at greater risk of depression.

ABSTRACT

AIM: The aim of the present study was to evaluate labiopalatal angulation of maxillary anterior teeth using Custom-made jig, Profile projector, and ImageJ computer software methods.

MATERIALS AND METHODS: The subjects for this study were selected in the age-group of 20-30 years having permanent dentition, including 2nd molars and bilateral Angle’s class 1 molar and canine relationship. Recording the labiopalatal angulation in proximal view was carried out by using one manual method and two digital methods namely using Custom-made jig, Profile projector, and ImageJ computer software, respectively. Alginate impressions were made for the subjects, and the spatial relationship of the maxilla to the cranium was recorded using a facebow. The casts were mounted in a semi-adjustable articulator, and the articulated mounted casts with the mounting ring were transferred to the Custom-made jig, and angulations were measured in proximal view. Digital methods of measurement were recorded by using Profile projector and ImageJ computer software methods. Data were tabulated and statistically analyzed.

RESULTS: In males, the mean labiopalatal angulation of maxillary right and left maxillary canines of Custom-made jig was 91.94 ± 1.47 and 91.70 ± 1.68, in Profile projector method 87.41 ± 3.75 and 87.58 ± 3.79, and in ImageJ computer software 84.23 ± 5.72 and 83.29 ± 6.74, respectively. In females, Custom-made jig was 91.82 ± 1.55 and 92.17 ± 1.84, in Profile projector method 86.70 ± 5.58 and 86.94 ± 5.57, and in ImageJ computer software 82.76 ± 6.34 and 83.05 ± 6.12, respectively. There was a very high statistically significant difference found between different methods.

CONCLUSION: In conclusion, the values obtained in the digital methods (i.e., both the Profile projector and ImageJ computer software) were more accurate than the manual method. However, the ImageJ computer software was most reliable in comparison with the values obtained in Profile projector.

CLINICAL SIGNIFICANCE: The labiopalatal angulation of anterior teeth will act as a guideline in re-establishing the correct angulations and the anatomic contours of the maxillary arch to achieve the desired esthetics that provide adequate lip support and to restore the required functions.

ABSTRACT

AIM: The aim of this study was to assess, in vitro, the human pulp dissolution capacity of 500 ppm and 200 ppm of hypochlorous acid in comparison with 5.2% sodium hypochlorite (NaOCl).

MATERIALS AND METHODS: Forty pulp tissue samples were standardized to a weight of 9 mg and divided into four groups according to the irrigating solution used: 5.25% NaOCl, 500 ppm hypochlorous acid, 200 ppm hypochlorous acid, and distilled water. Eppendorf tubes carrying 2 mL of the irrigants were taken and the pulp tissue samples were placed in the tubes for the specified time interval: Subgroup A: 30 minutes and subgroup B: 60 minutes. After the designated time interval, the solution from each sample tube was filtered using Whatman filter paper and left for drying overnight. The residual weight was calculated by filtration method. The mean dissolution time for each experimental group at the different time intervals was statistically analyzed.

RESULTS: Mean tissue dissolution increases with an increase in the time period. Approximately 5.25% NaOCl was most effective at both time intervals followed by 500-ppm hypochlorous acid at 60 minutes. Least amount of tissue dissolution was shown by 200-ppm of hypochlorous acid at 30 minutes. Distilled water did not show the ability to dissolve human pulp tissue.

CONCLUSION: Within the limitations of the study, 5.25% NaOCl dissolved the pulp tissue most efficiently at both time intervals and both concentrations. Human pulp tissue dissolution by hypochlorous acid was found to gradually increase with time and with an increase in its concentration.

CLINICAL SIGNIFICANCE: With the basic information that hypochlorous acid does have the capacity to dissolve human pulp tissue, further research can be undertaken to assess methods to increase its efficiency. Sooner than later, hypochlorous acid may be able to completely replace the toxic NaOCl in clinical practice, as the irrigant of choice during root canal therapy.

ABSTRACT

The purpose of the present study is to evaluate the fracture resistance and the fit of CAD-CAM produced inlay-retained fixed partial dentures. Eighteen experimental groups were generated according to different CAD-CAM ceramic materials (zirconia, lithium disilicate, and zirconia-reinforced lithium silicate), different connector dimensions (12, 14, and 16 mm²), and application of thermomechanical-aging (1,200,000 cycles of cyclic loading with simultaneous thermal cycling). Gap values of thermomechanically-aged groups were measured by using periapical radiographs. Then, the specimens were tested for fracture resistance and failure types were examined. The results were statistically analyzed (α=0.05). Higher gap values were observed after aging. Zirconia showed the highest fracture resistance values among the most of the experimental groups. In non-aged groups, the most frequent failure type was decementation in zirconia group. In the aged groups, the most frequent failure type was molar connector fracture. Thermomechanical-aging increased the gap values and decreased the fracture resistance values.

ABSTRACT

OBJECTIVE: To identify prenatal and postnatal risk factors associated with surfactant redosing.

STUDY DESIGN: Retrospective, single-regional center study including all infants born from 24+0 to 31+6 weeks of gestation in the Marche Region, Italy, and admitted to a single level III regional NICU from January 1, 2004, to February 28, 2021. Clinical factors associated with surfactant redosing were identified through logistic regression analysis.

RESULTS: Of 1615 consecutive admissions, 662 infants were treated with exogenous surfactant: 462 (70%) received a single dose and 200 (30%) received more than one dose (25.5% two doses and 4.5% three doses). Risk of redosing was higher for infants born to mothers with hypertension in pregnancy (OR 3.95, p<0.001), for small for gestational age infants (OR 3.93, p<0.001) and when the first surfactant dose was 100mg/kg instead of 200mg/kg (OR 4.56/4.61, p<0.001). Infants with greater gestational age, delayed first surfactant administration, and milder respiratory distress syndrome had reduced risk of redosing. Infants who required multiple surfactant doses had a higher rate of bronchopulmonary dysplasia and mortality, as well as longer duration of respiratory support than patients that received one dose.

CONCLUSION: Hypertension in pregnancy and small-for-gestational age status were found to be statistically and clinically significant predictors of surfactant redosing. Understanding the pathophysiology of these conditions requires further investigation.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Various studies have identified single-nucleotide polymorphisms (SNPs) associated with nonalcoholic fatty liver disease (NAFLD) and related traits, including ones located in or near the LYPLAL1, GCKR, PPP1R3B, TM6SF2, MBOAT7, and PNPLA3 genes. However, these SNPs were identified primarily in populations of European ancestry. This study examined the associations of these previously identified SNPs with hepatic steatosis in a sample of Mexican-origin adults living in Southern Arizona.

MATERIALS AND METHODS: A total of 307 Mexican-origin adults between the ages of 18 and 64 with a body mass index (BMI) of 25 kg/m2 or higher were genotyped at the following SNPs: rs12137855 (LYPLAL1), rs1260326 (GCKR), rs4240624 (PPP1R3B), rs58542926 (TM6SF2), rs641738 (MBOAT7), and rs738409 (PNPLA3). Hepatic steatosis was assessed by transient elastography (FibroScan®) with controlled attenuation parameter. Regression models examined the association between each of the six SNPs and hepatic steatosis. BMI was examined as a potential modifier of the genetic associations.

RESULTS: Participants were, on average, 45 years old and mostly female (63%) with an overall mean hepatic steatosis of 288.1 dB/m. Models showed no associations between LYPLAL1, GCKR, PPP1R3B, TM6SF2, or MBOAT7 and hepatic steatosis. Only PNPLA3 was statistically significantly associated with hepatic steatosis in both unadjusted and adjusted models (p<0.01). There was no effect modification observed with BMI.

CONCLUSIONS: SNPs associated with NAFLD in populations of European descent did not strongly contribute to hepatic steatosis in individuals of Mexican-origin, except for rs738409 (PNPLA3). Further efforts are necessary to explore additional SNPs that may be associated with NAFLD in this high-risk population.

ABSTRACT

OBJECTIVE: We aimed to evaluate the impact of a multidisciplinary pulmonary embolism response team on the management and outcomes of patients with acute pulmonary embolism.

METHODS: We retrospectively reviewed all patients presenting to our institution with a diagnosis of PE from July 2020 to April 2022. The primary outcome measures were in-hospital mortality, major bleeding events defined by the International Society on Thrombosis and Haemostasis (ISTH), and utilization of catheter-directed interventions (CDI). Secondary outcome measures included 30-day and 12-month mortality, hospital and intensive care unit (ICU) length of stay (LOS), vasopressor requirement, and cardiac arrest. Continuous variables were assessed with the Mann-Whitney U test and categorical variables were assessed with the chi-square or Fisher’s exact test when appropriate.

RESULTS: Two hundred and seventy-nine patients with acute PE were identified with 79 (28%), 173 (62%), and 27 (10%) stratified as low-risk, intermediate-risk, and high-risk, respectively. There were 133 (47.7%) PERT activations. Saddle and main pulmonary artery embolisms (P<0.001), RV strain (P=0.001), RV dysfunction (P<0.001), co-existing deep vein thrombosis (P<0.001), and dyspnea as a presenting symptom (P=0.008) were significantly associated with PERT activation. Patients evaluated by PERT were more likely to undergo CDI (49% vs. 27%, P<0.001) across risk stratification, and less likely to have an IVC filter placed (1% vs. 5%, P=0.04). PERT consultation had numerical but non-statistically significant trends towards reduced in-hospital (2% vs. 5%, P=0.2) and 30-day mortality (2% vs. 8%, P=0.06), but similar rates of 12-month mortality (7% vs. 8%, P=0.7). PERT activation was also associated with trends towards reduced rates of major bleeding (2% vs. 7%), cardiac arrests (2% vs. 7%), and vasopressor requirement (9% vs. 18%). PERT consultation decreased median ICU days by half; however, we did not observe any difference in total hospital LOS between groups.

CONCLUSIONS: At our institution, PERT was associated with significantly higher utilization of CDIs and improved clinical outcomes including reduced mortality and major bleeding events. PERT was also associated with less ICU days, suggesting a possible economic benefit of implementing PERT teams, although further research is needed to confirm that conclusion.
