Environmental Exposure to Pesticides and the Risk of Child Neurodevelopmental Disorders.

Background and Objectives: Neurodevelopment is a fragile brain process necessary for learning from the beginning of childhood to adulthood. During the procedure, several risks could affect it, including environmental factors such as neurotoxic chemicals or environmental pollutants and, within them, exposure to pesticides. Materials and Methods: This ecological descriptive study attempted to assess the association between environmental exposure to pesticides and neurodevelopmental disorders. This study was conducted on 4830 children diagnosed for 11 years in a total population of 119,897 children in three areas: high, medium, and low greenhouse concentrations. Results: Chromosomal abnormalities were the most common prenatal disorder (28.6%), while intrauterine physical factors were the least common (0.5%). Among perinatal diagnoses, gestational age less than 32 weeks was the most common (25%), while hyperbilirubinemia requiring exchange transfusion and birth complications was the least common (0.4%). Brain damage was the most common problem detected in postnatal diagnosis (36.7%), while unspecified postnatal abnormalities were the least common (3.1%). Conclusions: The areas with the highest greenhouse concentration had higher incidences of neurodevelopmental disorders, particularly in boys, and lower age of referral. Chromosomal abnormalities were prevalent for prenatal diagnoses, gestational age below thirty-two weeks for perinatal diagnoses, and brain damage for postnatal diagnoses. Future studies should analyze the connection between pesticide exposure and neurodevelopmental disorders using spatial point pattern analysis.

Renal tubular dysfunction in greenhouse farmers exposed to pesticides unveiled by a panel of molecular biomarkers of kidney injury.

Growing evidence suggests that chronic exposure to pesticides may cause adverse effects on the health of the exposed population leading to organ-specific toxicity, including kidney damage. Traditional markers used to assess renal function (glomerular filtration rate (GFR), and serum creatinine and cystatin C -Cys-C-) are inadequate to evaluate a potential subclinical renal impairment linked to occupational exposure to pesticides, since levels above the upper limit of normal only occur when renal damage is very extensive. The use of more sensitive biomarkers is therefore needed. This study investigated novel urinary biomarkers of kidney function (microalbuminuria, osteopontin (OPN), trefoil factor 3 (TFF3), ß-2-microglobulin, neutrophil gelatinase-associated lipocalin (NGAL), and Cys-C), together with the aforementioned traditional serum biomarkers, to assess potential kidney damage in farmers exposed to pesticides in an intensive agriculture setting. The study population consisted of 175 greenhouse workers and 91 healthy control subjects from Almeria (Southeastern Spain), a major hub of greenhouse agriculture. Data were collected at two different time-points of the same crop season: a period with greater pesticide use (high exposure period) and another with lower pesticide use (low exposure period). Significantly higher urinary levels of OPN and TFF3 were found in greenhouse workers than in controls, and in the high pesticide exposure period compared to that of low exposure. These changes suggest a subclinical tubular damage linked to pesticide exposure. In contrast, microalbuminuria, GFR, serum creatinine and Cys-C failed to be associated with pesticide exposure, suggesting that glomerular function was spared. Increased OPN and TFF3 levels over time may suggest a gradual progression from tubular dysfunction to chronic kidney disease in the exposed population.

Coronary Artery Bypass Grafting Versus Percutaneous Coronary Intervention in Patients with Left Ventricular Systolic Dysfunction.

PURPOSE: There is a paucity of comparative data examining the optimal revascularization strategy in patients with left ventricular systolic dysfunction (LVD). METHODS: We performed an aggregate data meta-analysis of clinical outcomes comparing percutaneous coronary intervention (PCI) versus coronary artery bypass (CABG) in patients with LVD (left ventricle ejection fraction (LVEF) of ≤ 40%), using the random effects model. Effects size is reported as odds ratio (OR) and a 95% confidence interval. Outcomes included all-cause mortality, myocardial infarction, stroke, repeat revascularization, and a composite of major adverse cardiac and cerebrovascular events (MACCE) at 30-day, 3-year, and long-term (6.3 ± 0.9 years) follow-ups. Seventeen studies (16 observational, 1 randomized) and 18,599 patients (CABG 9651; PCI 8948) were included. RESULTS: PCI and CABG had comparable all-cause mortality at 30 days (OR 0.78, 95% CI 0.49-1.23) and 3 years (OR 1.05, 95% CI 0.91-1.21); however, PCI was associated with increased long-term morality after a mean follow-up of 6.3 ± 0.9 years (31.6% vs. 24.3%, OR 1.41, 95% CI 1.21-1.64). A similar mortality trend was observed in the subgroup of patients with EF ≤ 35%. PCI had a higher rate of repeat revascularization at 3-year and long-term follow-ups. The long-term rates of stroke and MI were comparable. PCI, on the other hand, had lower rates of stroke at 30-day and 3-year follow-ups. CONCLUSION: CABG was associated with lower rates of long-term mortality and revascularization but higher rate of upfront stroke in patients with LVD. However, the data included consisted predominantly of observational studies, highlighting the paucity and need for randomized trials.

Multivessel PCI for Acute Myocardial Infarction: Where Do We Stand After The COMPLETE Trial?

PURPOSE OF REVIEW: Multivessel coronary artery disease is frequently encountered in patients undergoing primary percutaneous coronary intervention (PCI). Several moderate-sized randomized trials have suggested that complete revascularization of non-culprit stenoses in ST-elevation myocardial infarction (STEMI) patients without cardiogenic shock is associated with improved outcomes driven solely by a reduction in the risk of future revascularization. RECENT FINDINGS: The Complete versus Culprit-only Revascularization to Treat Multi-vessel disease after Early PCI for STEMI (COMPLETE) trial recently showed that a complete revascularization strategy for non-culprit stenoses for STEMI patients without cardiogenic shock, performed either during the index hospitalization or after discharge, reduces the risk of cardiac mortality or myocardial infarction (MI) driven by a reduction in the risk of MI at a median of 3 years. In STEMI patients without cardiogenic shock undergoing primary PCI, a complete revascularization strategy for non-culprit stenoses, performed either during the index hospitalization or shortly after discharge, improves outcomes and should be considered as the default strategy whenever feasible.

Bilateral internal mammary artery laceration after cardiac pulmonary resuscitation.

Cardiopulmonary resuscitation (CPR) is essential for the survival of cardiac arrest patients. High-quality chest compressions are critical for survival, but energetic resuscitation efforts can lead to chest injuries. Internal mammary artery (IMA) injury is a rare complication of CPR, but can lead to life-threatening intrathoracic hemorrhage. Early detection of IMA injury should be considered in all post cardiac arrest syndrome (PCAS) with anemia refractory to transfusion. To the best of our knowledge, no cases of CPR-associated bilateral IMA laceration have ever been reported. We report a unique CPR complication resulting in anterior mediastinal hemorrhage that was detected by ECHO, verified by computed tomography angiography, and treated with endovascular intervention.

One-Year Mortality in Patients Undergoing Transcatheter Aortic Valve Replacement for Stenotic Bicuspid versus Tricuspid Aortic Valves: A Meta-Analysis and Meta-Regression.

OBJECTIVE: To assess 1-year mortality after transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic stenosis (AS). BACKGROUND: Clinical trials have proven the beneficial effect of TAVR on mortality in patients with tricuspid AS. Individuals with bicuspid AS were excluded from these trials. METHODS: A meta-analysis using literature search from the Cochrane, PubMed, ClinicalTrials, SCOPUS, and EMBASE databases was conducted to determine the effect of TAVR on 1-year mortality in patients with bicuspid AS. Short-term outcomes that could potentially impact one-year mortality were analyzed. RESULTS: After evaluating 380 potential articles, 5 observational studies were selected. A total of 3890 patients treated with TAVR were included: 721 had bicuspid and 3,169 had tricuspid AS. No statistically significant difference between the baseline characteristics of the two groups of patients was seen outside of mean aortic gradient. Our primary endpoint of one-year all-cause mortality revealed 85 deaths in 719 patients (11.82%) with bicuspid AS compared to 467 deaths in 3100 patients (15.06%) with tricuspid AS, with no difference between both groups [relative risk (RR) 1.03; 95% CI 0.70-1.51]. Patients with bicuspid AS were associated with a decrease in device success (RR 0.62; 95% CI 0.45-0.84) and an increase in moderate-to-severe prosthetic valve regurgitation (RR 1.55; 95% CI 1.07-2.22) after TAVR compared to patients with tricuspid AS. The effect of meta-regression coefficients on one-year all-cause mortality was not statistically significant for any patient baseline characteristics. CONCLUSION: When comparing TAVR procedure in tricuspid AS versus bicuspid AS, there was no difference noted in one-year all-cause mortality.

Suspected coronary fat embolism after liposuction.

A 38-year-old female presented with chest pain and ST elevation on electrocardiogram after an outpatient liposuction procedure. Emergent coronary angiography revealed complete occlusion of multiple coronary arteries, with fat embolism as the suspected etiology. Attempts to restore distal coronary flow with balloon dilatation, aspiration with Pronto catheter, and distal adenosine administration resulted in minimal improvement in flow. The material aspirated was consistent with fat. With supportive therapy, including Impella CP support, the patient's clinical condition improved. To our knowledge, this is the first reported case of multiple coronary occlusion after liposuction.

Bioactive compounds of the Mediterranean diet and prostate cancer.

OBJECTIVE: The purpose of this review is to examine the evidence on the effects of bioactive constituents of the Mediterranean diet (MeDi) on prostate cancer (PCa) risk. METHODS: The search for articles came from extensive research in the following databases: PubMed, Scopus, and Web of Science. We used the search terms "Mediterranean diet," "lycopene," "vitamin E," "vitamin C," "Selenium," "resveratrol," "prostate cancer," and combinations, such as "lycopene and prostate cancer" or "resveratrol and prostate cancer." RESULTS: Numerous studies investigating the effect of various dietary nutrients on PCa have suggested that selenium is probably the most promising. Several studies reported reduced PCa risk associated with vitamin C and E intake, while other studies reported no association. Lycopene inhibits cell proliferation and inducts apoptosis, thus protecting against cancer. Also, it has been found in various in vivo and in vitro studies that resveratrol, inhibits PCa development. CONCLUSIONS: The high content of bioactive phytochemicals in the MeDi is of particular interest in the prevention of PCa. Further large-scale studies are required to clarify the effect of MeDi bioactive compounds on prostate health, in order to establish the role of this diet in the prevention of PCa.

Biomarkers of oxidative stress in blood of workers exposed to non-cholinesterase inhibiting pesticides.

In occupational settings workers are often exposed to pesticides at relatively high doses compared to environmental exposures. Long-term exposure to pesticides has been associated with numerous adverse health effects in epidemiological studies, and oxidative stress is often claimed as one of the underlying mechanisms. In fact, different pesticides have been reported to induce oxidative stress due to the generation of free radicals and/or alteration in antioxidant defense enzymes. The present study examined greenhouse workers regularly exposed to diverse pesticides under integrated production system, and a group of controls of the same geographic area without any chemical exposure. Two different periods of the same crop season were assessed, one of high exposure (with greater use of pesticides) and other of low exposure (in which a less use of these compounds was made). Non-specific biomarkers of oxidative stress, e.g. thiobarbituric acid reactive substances (TBARS), ferric reducing ability of serum (FRAS), total thiol groups (SHT), gamma-glutamyl transpeptidase (GGT) and paraoxonase-1 (PON1) were measured in serum samples from all study subjects, alongside erythrocyte acetylcholinesterase (AChE). Results are suggestive of a mild increase in oxidative stress associated with pesticide exposure, which was compensated by an adaptive response to raise the antioxidant defenses and thus counter the detrimental effects of sustained oxidative stress. This response led to significantly increased levels of FRAS, SHT and PON1 in greenhouse workers relative to controls. Furthermore, AChE was decreased likely as a result of oxidative stress as workers did not use organophosphate insecticides.

Coronary Physiology Assessment for the Diagnosis and Treatment of Stable Ischemic Heart Disease.

Coronary artery disease is the most prevalent cardiovascular disease in the USA. In the majority of settings, percutaneous coronary intervention (PCI) for stable coronary artery disease (CAD) reduces angina and improves quality of life; however, it does not improve survival and is associated with infrequent but serious complications. Selection of appropriate patients and coronary lesions for revascularization with PCI is crucial to maximize the benefit-to-risk ratio. The assessment of the hemodynamic significance of intermediate coronary lesions has been shown to improve outcomes and reduce healthcare costs. The current review summarizes the existing evidence regarding the physiological assessment of coronary lesions, with emphasis on fractional flow reserve, the most common invasive hemodynamic assessment modality.

Acute Coronary Syndromes: Unstable Angina and Non-ST Elevation Myocardial Infarction.

Non-ST elevation acute coronary syndromes (NSTE-ACS) encompass the clinical entities of unstable angina and non-ST elevation myocardial infarction. Several advances have occurred over the past decade, including the emergence of new antiplatelet and antithrombotic therapies and novel treatment strategies, leading to marked improvements in mortality. However, there has also been an increased incidence in NSTE-ACS as a result of the use of high-sensitivity troponins and the increase in cardiovascular risk factors. This article provides a focused update on contemporary management strategies pertaining to antiplatelet, antithrombotic, and anti-ischemic therapies and to revascularization strategies in patients with ACS.

A Th2-type immune response and low-grade systemic inflammatory reaction as potential immunotoxic effects in intensive agriculture farmers exposed to pesticides.

Pesticides are chemicals widely used in agriculture to keep crops healthy and prevent them from being destroyed by pests, thus contributing to a sustainable food and feed production. However, long-term exposure to these compounds may be harmful to human health as they can affect the function of various organs systems, including the immune system. There is growing evidence that pesticides may increase the risk of developing immune-based diseases and inflammation. This study assessed whether greenhouse farmers occupationally exposed to pesticides presented alterations in immunoregulatory proteins, used as surrogate biomarkers of immune function. The study population consisted of 175 greenhouse workers occupationally exposed to pesticides and 91 non-exposed controls. Serum levels of 27 cytokines, chemokines and growth factors were measured using a magnetic bead-based immunoassay in a subpopulation of 111 greenhouse workers and 79 non-exposed controls. Since analytical determinations were performed in two periods of the same crop season with different use of pesticides (period of high and low pesticide exposure), linear mixed models for repeated measures were used to optimize statistical inference. The increase in IL-13, IL-4 and IL-6 observed in greenhouse workers compared to controls, and in the period of high exposure to pesticides relative to that of low exposure, suggest an altered Th1/Th2 balance towards the Th2 response. This finding points to a type-2 inflammation commonly presented as allergic inflammation, which has often been reported in farm-workers and in which pesticide exposure is considered a risk factor. Furthermore, the increase in IL-1ß and VEGF, mediators of inflammation and angiogenesis, may suggest a low-grade systemic inflammation that might underlie chronic pathological conditions linked to pesticide exposure.

The problem of calculating the prevalence of sexual dysfunction: a meta-analysis attending gender.

INTRODUCTION: Sexuality is an integral part of human health, and sexual dysfunctions are prevalent issues that affect men and women. While reviews on sexual dysfunctions in various diseases have been conducted, overall data are scarce. OBJECTIVES: To update the overall prevalence of sexual dysfunctions from available prevalence studies on both sexes. METHODS: We used a 2-phase selection process to include cross-sectional studies that were conducted on the adult population and published between 2017 and 2022. The extracted data were prevalence, methodology, sample size, and location. Sensitivity and subgroup analyses were conducted to assess heterogeneity. RESULTS: This review analyzed 4407 studies. Twenty-three met the established criteria: 9 on the male population and 14 on the female population. The meta-analysis included 7 articles on males and 13 on females. The prevalence of sexual dysfunction was 31% in men and 41% in women, with significant heterogeneity among the studies. Sociocultural differences and use of varying measurement methods were identified as the main factors contributing to heterogeneity. Subgroup analysis revealed decreased heterogeneity among studies that used the Female Sexual Function Index as a diagnostic tool for females. CONCLUSIONS: The review highlights the notable variability in results due to methodological and geographic variations. Therefore, enhancing the training of professionals and standardizing the recording of patient data-through the Female Sexual Function Index and Male Sexual Health Questionnaire or by developing new ones for this purpose-could improve the consistency of research on sexual health.

Neuropsychiatric symptoms of patients two years after experiencing severe COVID-19: A mixed observational study.

BACKGROUND: The impact of SARS-CoV-2 infection (COVID-19) on mental health has not been extensively studied in the medium and long term. This study assessed how clinical, biological, and social factors affect mental health in patients who recovered from severe COVID-19. The evaluation was done 90 days after hospital discharge and followed up at 12 and 24 months. METHODS: A retrospective-prospective cohort mixed observational study was conducted on patients over 18 years of age who required hospitalization in Internal Medicine or ICU for severe COVID-19 pneumonia during 2020 and 2021. Demographic information, clinical variables, and data for the scales were obtained from electronic medical records and telephone interviews. For comparisons of the different variables in each clinical variable (insomnia, depression, anxiety), the Student's t-test for independent samples has been used (normal distribution); otherwise, the Mann-Whitney test will be used. All tests and intervals will be performed with a confidence level of 95. Fisher's exact or Pearson's Chi-square test has been used as appropriate for qualitative variables. RESULTS: 201 patients were recruited. 37.3% presented insomnia, 22.4% anxiety, and 21.4% depressive symptoms. A direct association was established between female sex and depressive symptoms. Psychotropic history, fatigue, and C-reactive protein levels (CRP) were correlated with depression. Anosmia and ageusia, CRP, cognitive symptoms, and dyspnea predicted insomnia. Sex, orotracheal intubation (OTI), pain, fatigue, mental health history, and academic level were independent predictors of anxiety. High percentages of depressive, anxiety, and insomnia symptoms were detected in the second month after discharge and persisted at 12 and 24 months. The fatigue variable maintained a significant relationship with depressive symptoms at 2, 12 and 24 months. A possible limitation could be recall bias in retrospective data collection. CONCLUSIONS: This is a novel study to follow up on mental health for two years in patients with severe COVID-19. Clinical, biological, and psychosocial variables could be predictors of depressive symptoms, anxiety, and insomnia. The psychiatric symptoms persisted throughout the 2-year follow-up. These findings are critical for the follow-up of these patients and open the possibility of further studies in the medium and long term.

Impact of breastfeeding on ICU admissions and need for mechanical ventilation in infants younger than 6 months with RSV+ bronchiolitis. An observational study.

INTRODUCTION: This work aimed to analyze whether breastfeeding is a predictive factor for admission to ICU or needing mechanical ventilation in children under 6 months with RSV+ respiratory infection. METHODS: A retrospective cohort study was performed in three hospitals. Binary and multiple logistic regression analyses were performed to evaluate the association of variables with admission to the ICU or receiving mechanical ventilation. RESULTS: We analyzed 414 admissions, of which 293 (70.8%) had received breastfeeding, 43 (8.1%) were admitted to the ICU, and 26 (5.4%) required mechanical ventilation. Bivariate analysis showed that breastfeeding for at least 15 days and a longer duration of breastfeeding were associated with a lower risk of admission to the ICU and requiring mechanical ventilation. Multivariate analysis showed that not having been breastfed for at least 1 month was predictive of ICU admission; not having been breastfed for at least 2 months was predictive of needing mechanical ventilation. CONCLUSIONS: Breastfeeding for as little as 15-28 days could be associated with a lower risk of ICU admission and requiring mechanical ventilation in infants younger than 6 months admitted for RSV+ bronchiolitis. Since breastfeeding is one of the few protective factors that can be promoted, this finding is relevant for current clinical practice and the development of health promotion programs. Future studies can compare their results to ours.

Percutaneous coronary intervention vs. coronary artery bypass graft surgery for unprotected left main coronary artery disease in the drug-eluting stents era--an aggregate data meta-analysis of 11,148 patients.

BACKGROUND: Patients with unprotected left main coronary artery (LMCA) disease are increasingly treated with percutaneous coronary intervention (PCI) using drug-eluting stents (DES), but its benefits compared with coronary artery bypass grafting (CABG) remain controversial. We hypothesized that PCI with DES for unprotected LMCA disease is safe and effective compared with CABG. METHODS AND RESULTS: We performed aggregate data meta-analyses of clinical outcomes [death; non-fatal myocardial infarction (MI); stroke; repeat revascularization; and major adverse cardiac and cerebrovascular events (MACCE)] in studies comparing PCI with DES vs. CABG in patients with LMCA disease. A comprehensive literature search (01/01/2003 to 12/01/2011) identified 27 studies comparing PCI and CABG (11,148 patients). Summary odds ratios (OR) were calculated using a random-effects model. At 30 days, PCI for unprotected LMCA disease was associated with lower MACCE [odds ratio (OR) 0.57, 95% confidence interval (CI) 0.36-0.89) and stroke rates (OR 0.22, 95% CI 0.11-0.44) compared with CABG. At 12 months, the PCI group experienced higher rates of repeat revascularization (OR 3.72, 95% CI 2.75-5.03), but lower rates of stroke (OR 0.25, 95% CI 0.14-0.44) and all-cause death (OR 0.69, 95% CI 0.49-0.97). At the longest follow-up of 60 months, PCI was associated with equivalent mortality, lower rates of stroke (OR 0.42, 95% CI 0.28-0.62) and higher rates of MACCE (OR 1.30, 95% CI 1.10-1.55) and repeat revascularization (OR 3.54, 95% CI 2.75-4.54). CONCLUSIONS: In the DES era, PCI for unprotected LMCA disease is associated with equivalent mortality and MI, lower stroke rates and higher rates of repeat revascularization compared with CABG.

Compositional and material properties of rat bone after bisphosphonate and/or Strontium ranelate drug treatment.

PURPOSE: We investigated elemental strontium and/or bisphosphonate drug incorporation upon the compositional and biomechanical properties of vertebral bone, in a rat model of Osteoporosis secondary to ovariectomy. METHODS: Six month old female rats were ovariectomized (OVX) and divided into untreated OVX-Vehicle, OVX-RIS (Risedronate bisphosphonate [BP] treated), OVX-SrR (Strontium Ranelate [Protos®] treated), combination OVX-RIS+SrR, and sham-operated controls. After 16 weeks of treatment, rats were euthanized and lumbar vertebra were dissected. Micro-Computed Tomography (micro-CT), Electron Probe Micro-Analysis (EPMA), mechanical testing in compression and nano-indentation testing were then undertaken to evaluate bone morphometry, elemental composition, material properties and strength. RESULTS: Bone Volume was significantly reduced in the OVX-Vehicle (133±10 mm(3)) compared with OVX-RIS (169±22 mm(3)), OVX-SrR (145±2 mm(3)), and OVX-RIS+SrR (172±8 mm(3)). EPMA mapped elemental Sr deposition to the periosteal surface of cortical bone (50-100 µm thick), endosteal trabecular surfaces (20 µm thick), as well as to both vertebral growth plates. The atomic ratios of (Ca+Sr)/P were significantly reduced with SrR treatment (2.4%-6.6%), indicating Sr incorporation into bone mineral. No significant differences were measured in vertebral bone reduced modulus by nano-indentation. Conversely, all BP-dosed groups had significantly increased structural bone strength. CONCLUSIONS: Thus, we conclude that BP drugs dominate the conservation of trabecular geometry and structural strength in OP rats, whereas Sr drugs likely influence bone volume and material composition locally.

Association between right heart catheterization hemodynamics and glycosylated hemoglobin levels in adults with heart failure with reduced ejection fraction.

This study hypothesized that elevated glycosylated hemoglobin (HbA1c) levels are associated with abnormal right heart catheterization (RHC) hemodynamic parameters in patients with heart failure with reduced ejection fraction (HFrEF) and no prior diagnosis of diabetes. Methods: Retrospective cohort study of adult patients with HFrEF and no prior diagnosis of diabetes who underwent RHC and had HbA1c levels measured 30 days before or after the RHC. This study excluded patients who had received blood transfusions within 90 days prior to HbA1c measurement and patients with known diabetes. Univariate and multivariate regression analyses adjusted for age, sex, and BMI were used to test for an association between RHC hemodynamic parameters and HbA1c levels. Results: A total of 136 patients were included with a mean age of 55 ± 15 years and mean HbA1c was 5.99 ± 0.64%. Unadjusted univariate models showed that HbA1c is significantly associated with cardiac index (CI) by the Fick method and thermodilution, right atrial pressure (RAP), and mean pulmonary arterial pressure (MPAP). After multivariate analysis, for every one unit increase in HbA1c, there was a 0.19 and 0.26 L/min/m2 decrease in expected CI by thermodilution and by the Fick method (P = 0.03 and P < 0.01), respectively. For every one unit increase in HbA1c, there was a 2.39 mmHg increase in expected RAP (P = 0.01). Conclusion: Elevated HbA1c levels measured within 30 days before or after the index RHC in patients with a left ventricular ejection fraction <40% were associated with congestive hemodynamic parameters.

Social and Preventive Factors That Explain Oral Health among Pregnant Women in the Canton of Cuenca, Ecuador.

(1) Background: pregnant women in underprivileged areas may face challenges that affect their oral health. The analysis of these issues such as toothaches or cavities, among others could be crucial for them. However, no studies have been conducted in Cuenca, Ecuador. Thus, this study aimed to create a model explaining how social factors and healthy habits impact oral health in Cuenca, Ecuador. (2) Methods: An observational study was performed using a questionnaire developed from scratch. Principal component factor analysis was performed to calculate the oral disease index based on the oral health issues reported by women during pregnancy. (3) Results: 1971 women participated in the research. In total, 88% reported at least one oral health problem, with cavities (34%) and bleeding gums (33%) as the most prevalent. The rate of preventive visits and frequent brushing were the two variables that most impacted the oral disease index. The consumption of sweets, age, and the belief that visiting the dentist harms their unborn child were also important factors. However, income, education, and ethnic background showed little to no effect. (4) Conclusions: The most beneficial determinants of oral health factors in pregnant women in Cuenca, Ecuador, are preventive dentist visits, frequent brushing, and a contained consumption of sweets. The main harmful factors are age and the misconception that dental visits can harm their unborn child. Surprisingly, income, education, and ethnic background have little effect. This study can be replicated in other countries and cultures.

Comparison of Easy-to-Use Bronchiolitis Scores in the Post-COVID-19 Era-An Observational Study.

In the post-restrictions COVID-19 period, the incidence of bronchiolitis in infants has increased considerably. Several scores determine the degree of severity of the bronchiolitis episode, but few are clinician-friendly. The main aim of this research was to find the easy-to-use score that most accurately estimated the severity of patients' infections according to their clinical situations and most accurately predicted the need for hospital admission. An observational cross-sectional study was performed in a reference pediatric hospital during the post-restrictions period of the COVID-19 pandemic (2021 and 2022). A comparison was made between the severity estimate provided by five international acute bronchiolitis scales and the clinical severity of the acute bronchiolitis episode. Three hundred and seventy-seven patients participated in the investigation, with a mean age of 5.68 months; 68.7% of the participants had a mild episode of bronchiolitis, 24.5% had a moderate episode, and 6.9% had a severe episode. The severity estimated by the Tal scale modified by McCallum showed a statistically significant correlation with the clinical severity established by clinical criteria (0.836; p < 0.001). It showed a high correlation with other international scores, such as the Wang score (0.820; p < 0.05) and the Wood-Downes-Ferrés score (0.936; p < 0.001). In the multivariate analysis, the constituent variables of the modified Tal score appeared in the final model that predicts the need for hospital admission. In the context of increased incidence after COVID-19, the Tal score modified by McCallum is an easy-to-use measuring instrument that presents an excellent concordance with the clinical severity estimated at first care contact. It also offers a more significant prediction of the need for hospital admission.
