REPRODUCTIVE CYCLE STAGE ASSESSMENT IN THE TWO-TOED SLOTH (CHOLOEPUS HOFFMANNI), PRELIMINARY RESULTS.

The number of two-toed sloths (Choloepus hoffmanni) has significantly decreased in the last years. Deepening the knowledge of this tropical mammal's reproductive physiology is essential to improve captive breeding within conservation programs for this species. However, several aspects of its reproductive biology remain unexplored and have not been described sufficiently. The aim of this work was to describe the estrous cycle and reproductive physiology of two adult female C. hoffmanni by vaginal cytology, appearance of the external genitalia, and behavior. Vaginal cytology assay showed that the average duration of the estrous cycle was 15.1 ± 4.53 d. Positive correlations (P < 0.05) were found between the peak presence of superficial cells (estrous phase) and four parameters: aggressive behavior, pursuing behavior, vulvar swelling, and vaginal discharge. This pilot study, conducted on just two animals, forms a basis for a study design that may be employed for a more comprehensive assessment of the two-toed sloth reproductive physiology and behavior.

Microbiology and Biochemistry of Pesticides Biodegradation.

Pesticides are chemicals used in agriculture, forestry, and, to some extent, public health. As effective as they can be, due to the limited biodegradability and toxicity of some of them, they can also have negative environmental and health impacts. Pesticide biodegradation is important because it can help mitigate the negative effects of pesticides. Many types of microorganisms, including bacteria, fungi, and algae, can degrade pesticides; microorganisms are able to bioremediate pesticides using diverse metabolic pathways where enzymatic degradation plays a crucial role in achieving chemical transformation of the pesticides. The growing concern about the environmental and health impacts of pesticides is pushing the industry of these products to develop more sustainable alternatives, such as high biodegradable chemicals. The degradative properties of microorganisms could be fully exploited using the advances in genetic engineering and biotechnology, paving the way for more effective bioremediation strategies, new technologies, and novel applications. The purpose of the current review is to discuss the microorganisms that have demonstrated their capacity to degrade pesticides and those categorized by the World Health Organization as important for the impact they may have on human health. A comprehensive list of microorganisms is presented, and some metabolic pathways and enzymes for pesticide degradation and the genetics behind this process are discussed. Due to the high number of microorganisms known to be capable of degrading pesticides and the low number of metabolic pathways that are fully described for this purpose, more research must be conducted in this field, and more enzymes and genes are yet to be discovered with the possibility of finding more efficient metabolic pathways for pesticide biodegradation.

Population-Based COVID-19 Screening in Mexico: Assessment of Symptoms and Their Weighting in Predicting SARS-CoV-2 Infection.

Background and Objectives: Sentinel surveillance in the early stage of the COVID-19 pandemic in Mexico represented a significant cost reduction and was useful in estimating the population infected with SARS-CoV-2. However, it also implied that many patients were not screened and therefore had no accurate diagnosis. In this study, we carried out a population-based SARS-CoV-2 screening in Mexico to evaluate the COVID-19-related symptoms and their weighting in predicting SARS-CoV-2 infection. We also discuss this data in the context of the operational definition of suspected cases of COVID-19 established by the Mexican Health Authority's consensus. Materials and Methods: One thousand two hundred seventy-nine subjects were included. They were screened for SARS-CoV-2 using RT-PCR. The weighting of COVID-19 symptoms in predicting SARS-CoV-2 infection was evaluated statistically. Results: Three hundred and twenty-five patients were positive for SARS-CoV-2 and 954 were negative. Fever, asthenia, dysgeusia, and oxygen saturation predicted SARS-CoV-2 infection (odds ratios ranged from 1.74 to 4.98; p < 0.05). The percentage of asymptomatic COVID-19 patients was 36% and only 38.15% met the Mexican operational definition. Cq-values for the gene N of SARS-CoV-2 were significantly higher in asymptomatic subjects than in the groups of COVID-19 patients with neurological, respiratory, and/or musculoskeletal manifestations (p < 0.05). Conclusions: Dysgeusia, fever, and asthenia increased the odds of a positive result for COVID-19 1.74-4.98-fold among the study population. Patients with neurological, respiratory, and/or musculoskeletal manifestations had higher viral loads at COVID-19 diagnosis than those observed in asymptomatic patients. A high percentage of the participants in the study (61.85%) did not meet the operational definition for a suspected case of COVID-19 established by the Mexican Health Authority's consensus, representing a high percentage of the population that could have remained without a COVID-19 diagnosis, so becoming a potential source of virus spread.

Canine Dracunculus Nematode Infection, Toledo, Spain.

A fragment of a Dracunculus-like worm was extracted from the hind limb of a 2-year-old dog from Toledo, Spain. Cytochrome oxidase I and rRNA sequences confirmed an autochthonous mammalian Dracunculus worm infection in Europe. Sequence analyses suggest close relation to a parasite obtained from a North American opossum.

Emotions and feelings in critical and emergency caring situations: a qualitative study.

BACKGROUND: Moral emotions are a key element of our human morals. Emotions play an important role in the caring process. Decision-making and assessment in emergency situations are complex and they frequently result in different emotions and feelings among health-care professionals. METHODS: The study had qualitative deductive design based on content analysis. Individual interviews and focus groups were conducted with sixteen participants. RESULTS: The emerging category "emotions and feelings in caring" has been analysed according to Haidt, considering that moral emotions include the subcategories of "Condemning emotions", "Self-conscious emotions", "Suffering emotions" and "Praising emotions". Within these subcategories, we found that the feelings that nurses experienced when ethical conflicts arose in emergency situations were related to caring and decisions associated with it, even when they had experienced situations in which they believed they could have helped the patient differently, but the conditions at the time did not permit it and they felt that the ethical conflicts in clinical practice created a large degree of anxiety and moral stress. The nurses felt that caring, as seen from a nursing perspective, has a sensitive dimension that goes beyond the patient's own healing and, when this dimension is in conflict with the environment, it has a dehumanising effect. Positive feelings and satisfaction are created when nurses feel that care has met its objectives and that there has been an appropriate response to the needs. CONCLUSIONS: Moral emotions can help nurses to recognise situations that allow them to promote changes in the care of patients in extreme situations. They can also be the starting point for personal and professional growth and an evolution towards person-centred care.

Collaboration Between Maternal and Child Health and Chronic Disease Epidemiologists to Identify Strategies to Reduce Hypertension-Related Severe Maternal Morbidity.

INTRODUCTION: Maternal and child health (MCH) and chronic disease programs at state health agencies may not routinely collaborate. The objective of this study was to describe a project that enhanced relationships between MCH and chronic disease epidemiologists at the Florida Department of Health, increased epidemiologic capacity, and informed both programs. METHODS: We collaborated to assess hypertension-related severe maternal morbidity (H-SMM) and hypertensive disorders (preexisting hypertension, gestational hypertension, and preeclampsia) among women at delivery of their live birth to help determine the burden on health care systems in Florida. We identified ways to improve the health of women before they conceive and to help them manage any chronic diseases during the perinatal period. RESULTS: We found differences by maternal characteristics in H-SMM rates among 979,660 women who delivered live births. We proposed strategies to support collaboration between state MCH and chronic disease staff. First, increase the screening, monitoring, and management of hypertension before, during, and after pregnancy. Second, examine H-SMM concurrently with maternal mortality to help find prevention strategies. Third, include reproductive-aged women in ongoing hypertension prevention and intervention efforts. Fourth, expand team-based care to include obstetricians, midwives, and doulas who can work together with primary care providers for hypertension management. And fifth, create and share data products that guide various groups about hypertension and related risk factors among reproductive-aged women. CONCLUSION: The collaboration between the Florida Department of Health MCH and chronic disease epidemiologists produced 1) a program-relevant indicator, H-SMM and 2) strategies for enhancing program and clinical activities, communication, and surveillance to reduce H-SMM rates.

5p and 3p Strands of miR-34 Family Members Have Differential Effects in Cell Proliferation, Migration, and Invasion in Cervical Cancer Cells.

The micro RNA (miR)-34 family is composed of 5p and 3p strands of miR-34a, miR-34b, and miR-34c. The 5p strand's expression and function is studied in cervical cancer. The 3p strand's function and regulation remain to be elucidated. To study the function of the passenger strands of miR-34 family members, we overexpressed 5p and 3p strands using a synthetic miRNA in cervical cell lines. Cell proliferation was evaluated using crystal violet. Migration and invasion were tested using transwell assays, Western blot, and zymography. Possible specific targets and cell signaling were investigated for each strand. We found that miR-34a-5p inhibited proliferation, migration, and cell invasion accompanied by matrix metalloproteinase 9 (MMP9) activity and microtubule-associated protein 2 (MAP2) protein reduction. We also found that miR-34b-5p and miR-34c-5p inhibit proliferation and migration, but not invasion. In contrast, miR-34c-5p inhibits MMP9 activity and MAP2 protein, while miR-34b-5p has no effect on these genes. Furthermore, miR-34a-3p and miR-34b-3p inhibit proliferation and migration, but not invasion, despite the later reducing MMP2 activity, while miR-34c-3p inhibit proliferation, migration, and cell invasion accompanied by MMP9 activity and MAP2 protein inhibition. The difference in cellular processes, MMP2 and MMP9 activity, and MAP2 protein inhibition by miR-34 family members suggests the participation of other regulated genes. This study provides insights into the roles of passenger strands (strand*) of the miR-34 family in cervical cancer.

Pregnancy-Related Deaths, Florida, 1999-2012: Opportunities to Improve Maternal Outcomes.

Objectives To examine pregnancy-related deaths (PRDs) in Florida, to identify quality improvement (QI) opportunities, and to recommend strategies aimed at reducing maternal mortality. Methods The Florida Pregnancy-Associated Mortality Review (PAMR) Committee reviewed PRDs occurring between 1999 and 2012. The PAMR Committee determined causes of PRDs, identified contributing factors, and generated recommendations for prevention and quality improvement. Information from the PAMR data registry, and live births from Florida vital statistic data were used to calculate pregnancy-related mortality ratios (PRMR) and PRD univariate risk ratios (RR) with 95% confidence intervals (CI). Results Between 1999 and 2012, the PRMR fluctuated between 14.7 and 26.2 PRDs per 100,000 live births. The five leading causes of PRD were hypertensive disorders (15.5%), hemorrhage (15.2%), infection (12.7%), cardiomyopathy (11.1%), and thrombotic embolism (10.2%), which accounted for 65% of PRDs. Principal contributing factors were morbid obesity (RR = 7.0, 95% CI 4.9-10.0) and late/no prenatal care (RR = 4.2, 95% CI 3.1-5.6). The PRMR for black women was three-fold higher (RR = 3.3, 95% CI 2.7-4.0) than white women. Among the five leading causes of PRDs, 42.5% had at least one clinical care or health care system QI opportunity. Two-third of these were associated with clinical quality of care, which included standards of care, coordination, collaboration, and communication. The QI opportunities varied by PRD cause, but not by race/ethnicity. Conclusion Gaps in clinical care or health care systems were assessed as the primary factors in over 40% of PRDs leading the PAMR Committee to generate QI recommendations for clinical care and health care systems.

The emotion: A crucial component in the care of critically ill patients.

BACKGROUND: The acquisition of experience is a major concern for nurses in intensive care units. Although the emotional component of the clinical practice of these nurses has been widely studied, greater examination is required to determine how this component influences their learning and practical experience. OBJECTIVE: To discover the relationships between emotion, memory and learning and the impacts on nursing clinical practice. RESEARCH DESIGN: This is a qualitative phenomenological study. The data were collected from open, in-depth interviews. A total of 22 intensive care unit nurses participated in this research between January 2012 and December 2014. Ethical considerations: The School of Nursing Ethics Committee approved the study, which complied with ethical principles and required informed consent. FINDINGS: We found a clear relationship between emotion, memory and the acquisition of experience. This relationship grouped three dimensions: (1) satisfaction, to relieve the patient's pain or discomfort, give confidence and a sense of security to the patient, enable the presence of family members into the intensive care unit and provide family members with a realistic view of the patient's situation; (2) error experience, which nurses feel when a patient dies, when they fail to accompany a patient in his or her decision to abandon the struggle to live or when they fail to lend support to the patient's family; and (3) the feel bad-feel good paradox, which occurs when a mistake in the patient's care or handling of his or her family is repaired. CONCLUSION: Emotion is a capacity that impacts on nurses' experience and influences improvements in clinical practice. Recalling stories of satisfaction helps to reinforce good practice, while recalling stories of errors helps to identify difficulties in the profession and recognise new forms of action. The articulation of emotional competencies may support the development of nursing ethics in the intensive care unit to protect and defend their patients and improve their relationships with families in order to maximise the potential for patient care.

LEISHMANIA INFANTUM INFECTION IN BENNETT'S WALLABIES (MACROPUS RUFOGRISEUS RUFOGRISEUS) IN A SPANISH WILDLIFE PARK.

Although dogs are the main reservoir for human Leishmania infantum infection, the disease has also been reported in other domestic and wild mammals. In 2011, a fatal case of naturally acquired leishmaniosis was described for the first time in a Bennett's wallaby (Macropus rufogriseus rufogriseus) kept in a wildlife park in Madrid (Spain). This study was designed to assess the infection status of twelve Bennett's wallabies in the same park one year after this incident. Phlebotomus perniciosus, the main vector of L. infantum in Spain, was screened for using sticky and Centers for Disease Control miniature light traps. L. infantum infection was confirmed by molecular diagnosis in four animals, but only one wallaby returned a positive serology result. The presence of the sand fly vector was also confirmed in this habitat. These results suggest that the first case of L. infantum in a wallaby in this park was not an isolated incident and stress the need for further work to determine the role of this parasite in the morbidity and mortality of these macropods. Madrid was recently the scene of an outbreak of human cutaneous and visceral leishmaniosis. Epidemiological studies have so far revealed the widespread presence of L. infantum infection in animals other than the dog. Our ongoing work suggests a risk of L. infantum infection not only among captive animals in Madrid, but also among threatened species or even species that are already extinct in the wild.

Synthesis of Chiral 1,4,2-Oxazaphosphepines.

Synthesis and structural characterization of 1,4,2-oxazaphosphepines is described. The 1,4,2-oxazaphosphepines were obtained from reaction of chiral 1,3-benzoxazines with dichlorophenylphosphine or triethyl phosphite. The configuration of some of these compounds was stablished by X-ray analysis.

First study on efficacy and tolerability of a new alkylphosphocholine molecule (oleylphosphocholine-OlPC) in the treatment of canine leishmaniosis due to Leishmania infantum.

The alkylphosphocholine oleylphosphocholine (OlPC) represents a potential new therapy for the treatment of canine leishmaniosis caused by Leishmania infantum. The aim of the present study was to evaluate the efficacy and safety of OlPC in a small cohort of dogs naturally infected with L. infantum and defined as clinically sick (LeishVet stages II and III). A total of eight dogs were included in the study and were treated orally with 4 mg/kg OlPC for 14 days. Dogs were assessed at the clinical and parasitological level at four time points during a total follow-up period of 90 days (before treatment and at 15, 30, and 90 days post-treatment onset). Ln-PCR, real-time quantitative PCR, antibody testing (IFAT), and culture of bone marrow aspirates were evaluated at the four time points. OlPC treatment induced a rapid and satisfactory clinical recovery in terms of clinical score reduction and weight gain, and treatment efficacy was found to be associated with a decrease in bone marrow parasitic load. Serological titers measured by IFAT were stable in any of the treated dogs at any time point after treatment. OlPC was well tolerated and no severe adverse events were noted in any of the treated dogs; even some dogs showed slight intestinal disorders. This proof-of-principle study is the first to show that short oral treatment with OlPC improves clinical signs of canine L. infantum leishmaniosis, highlighting the need to perform additional studies to optimize the dosing regimen and to assess long-term treatment efficacy of this drug.

Modeling of moisture content during baking with different approaches for effective diffusivity and evaluation of quality variables in baked potato slices.

Baking is a healthier alternative to frying, since texture, color, smell, and flavor are developed, without adding oil. The objective was to estimate the moisture content in potato slices, during baking using Fick's law of diffusion to model internal moisture transport and to assess the impact on quality attributes. Moisture transport kinetics were examined at three baking temperatures of 120, 130, and 140°C. Fick's law was employed to estimate average moisture content using different methods: considering both a constant (method of slopes by subperiods, MSS; and method of successive approximations, MSA) and a variable (represented as a quadratic function of time, QFT) behavior of effective diffusivity (De). Three quality variables were analyzed: water activity (aw, dew point hygrometry), total color difference (∆E, colorimetry), and fracturability (F, universal testing machine). The diffusivity estimated with the time-varying De method provided a more realistic description of moisture migration during baking. The aw, ∆E, and F for baked potato slices ranged from 0.234 to 0.276, 17.9 to 24.6, and 5.20 to 5.49 N, respectively. These attributes imply improved stability and extended shelf life, showing typical colors and texture changes for baked snacks. These changes are linked to variations in diffusivity, influenced by the size and quantity of micropores within the food structure. This study could allow an accurate prediction of mass transfer by considering variable De, facilitating the optimization of baking conditions. PRACTICAL APPLICATION: The analysis of the moisture content using Fick's law, considering a time-varying diffusivity, enables the optimization of the baking process for foods. This helps minimize the occurrence of defective products.

Pregnancy-related deaths due to pulmonary embolism: findings from two state-based mortality reviews.

This report presents findings from two state-based pregnancy-related reviews of deaths due to pulmonary embolism to describe prevalence, risk factors, and timing of symptoms and fatal events (N = 46). We examined the utility of state-based maternal mortality review teams as a means to gain more complete data on maternal deaths from which guidelines for prevention and intervention can be developed. The Florida Pregnancy-Associated Mortality Review Team and Virginia Maternal Mortality Review Team collaborated on findings from 9 years of pregnancy-related mortality review conducted in each state. Pregnancy-related deaths due to pulmonary embolism occurring within 42 days of pregnancy between 1999 and 2007 in Florida and Virginia were identified. Retrospective review of records was conducted to obtain data on timing of the fatal event in relation to the pregnancy, risk factors, and the presence and timing of symptoms suggestive of pulmonary embolism. Forty-six cases of pregnancy-related death due to pulmonary embolism were identified. The combined pregnancy-related mortality ratio (PRMR) was 1.6/100,000 live births. The PRMR for patients undergoing cesarean section delivery was 2.8 compared to 0.2 among those with vaginal deliveries (95 % CI = 1.8-4.2 and 0.1-0.5 respectively). Women aged 35 and older had the highest PRMR at 2.6/100,000 live births. BMI over 30 kg/m(2) and presence of chronic conditions were frequently identified risk factors. One in five decedents (21.7 %) reported at least two symptoms suggestive of pulmonary embolism in the days before death. This combined state-based maternal death review confirms age over 35 years, obesity, and the presence of chronic conditions are risk factors for pregnancy-related mortality due to venous thromboembolism in the US. Expanding and standardizing the process of state-based reviews offers the potential for reducing pregnancy-related mortality in the US.

Is effective contraceptive use conceived prenatally in Florida? The association between prenatal contraceptive counseling and postpartum contraceptive use.

The objective of this study is to describe the prevalence of postpartum contraceptive use among women experiencing a live birth in Florida in 2004-2005. To examine the association between family planning counseling during prenatal care visits and the use of effective contraceptive methods among postpartum women. Matched data from Florida PRAMS and Vital Statistics were used (n = 3,962). Weighted logistic regression was used to determine the association between prenatal family planning counseling and effective postpartum contraceptive use. Odds ratios were adjusted for use of contraception prior to pregnancy, well-baby checkup, race, ethnicity, nativity, education, marital status, poverty level, stress before or during pregnancy, and parity. Women who reported discussing family planning with their prenatal care provider were more likely to use effective contraception postpartum (AOR: 1.5, 1.1-2.0) compared to women who did not report a discussion. Women who used contraception prior to pregnancy (AOR: 2.3, 1.7-3.2) and women who experienced no stress before or during pregnancy (AOR: 2.0, 1.2-3.4) were also more likely to use contraception in the postpartum period. A significant interaction was identified between family planning counseling during prenatal visits and maternal education. Stratum specific odds ratios for women who received prenatal family planning counseling were significant for women with less than high school education (AOR: 2.5, 1.3-5.1) and for women with high school education (AOR: 2.0, 1.2-3.4). Women reporting family planning counseling during prenatal care were more likely to use effective contraception postpartum. While women with high school or less than high school education levels benefited from prenatal family planning counseling, the greatest benefit was observed for women with less than high school education. Integrating family planning counseling into prenatal care may increase the use of effective contraceptive methods among postpartum women.

Trends in contraceptive use among Florida women: implications for policies and programs.

Our study objective was to assess changes in effective contraceptive use among women at risk of unintended pregnancy in Florida in 2008 and 2009 compared with 2002 and 2004. Contraceptive use questions were available from Florida's Behavioral Risk Factor Surveillance System (BRFSS) for both periods (n = 4,606). Log binomial regression was used with appropriate methods to account for complex sampling in the BRFSS. We examined the change in four effective contraceptive use groups: sterilization, long-acting reversible contraceptive (LARC), short-acting reversible contraceptive (SARC), and barrier methods. Prevalence ratios comparing the two time periods were adjusted by demographic characteristics, employment, insurance status, children at home, poverty level, health behaviors, and health status. No evidence of change was found in sterilization (Adjusted Prevalence Ratio APR = 0.96; 95 % CI: 0.84-1.10) or SARC (APR = 1.01; 95 % CI: 0.87-1.18). The overall use of LARC increased and use of barrier methods decreased significantly over the two periods (APR = 1.68; 95 % CI: 1.09-2.60 and APR = 0.77; 95 % CI: 0.61-0.98, respectively). Only two population groups experienced significant changes in prevalence in the four use groups over this period. Non-Hispanic White women increased their use of LARC (APR = 2.89; 95 % CI: 1.58-5.29) and women who have never been married decreased their use of barrier methods (APR = 0.51; 95 % CI: 0.33-0.77). Contraceptive use in Florida continues to be low overall with some shift towards more effective long-term methods. New efforts are needed to promote and increase family planning practices, which include the use of effective contraceptives.

Reasons for the increasing Hispanic infant mortality rate: Florida, 2004-2007.

Assess whether the 55% increase in Florida's Hispanic infant mortality rate (HIMR) during 2004-2007 was real or artifactual. Using linked data from Florida resident live births and infant deaths for 2004-2007, we calculated traditional (infant Hispanic ethnicity from death certificates and maternal Hispanic ethnicity from birth certificates) and nontraditional (infant and maternal Hispanic ethnicity from birth certificate maternal ethnicity) HIMRs. We assessed trends in HIMRs (per 1,000 live births) using Chi-square statistics. We tested agreement in Hispanic ethnicity after implementation of a revised 2005 death certificate by using kappa statistics and used logistic regression to test the associations of infant mortality risk factors. Hispanic was defined as being of Mexican, Puerto Rican, Cuban, Central/South American, or other/unknown Hispanic origin. During 2004-2007 traditional HIMR increased 55%, from 4.0 to 6.2 (Chi-square, P < 0.001) and nontraditional HIMR increased 20%, from 4.5 to 5.4 (Chi-square, P = 0.03). During 2004-2005, agreement in Hispanic ethnicity did not change with use of the revised certificate (kappa = 0.70 in 2004; kappa = 0.76 in 2005). Birth weight was the most significant risk factor for trends in Hispanic infant mortality (OR = 1.33, 95% CI = 1.10-1.61). Differences in Hispanic reporting on revised death certificates likely accounted for the majority of traditional HIMR increase, indicating a primarily artifactual increase. Reasons for the 20% increase in nontraditional HIMR during 2004-2007 should be further explored through other individual and community factors. Use of nontraditional HIMRs, which use a consistent source of Hispanic classification, should be considered.

Child- and state-level characteristics associated with preventive dental care access among U.S. children 5-17 years of age.

The objectives of this study is to identify factors associated with lack of preventive dental care among U.S. children and state-level factors that explain variation in preventive dental care access across states. We performed bivariate analyses and multilevel regression analyses among 68,350 children aged 5-17 years using the 2007 National Survey of Children's Health data and relevant state-level data. Odds ratios (ORs) for child- and state-level variables were calculated to estimate associations with preventive dental care. We calculated interval odds ratios (IOR), median odds ratios (MOR), and intraclass correlation coefficients (ICC) to quantify variation in preventive dental care across states. Lack of preventive dental care was associated with various child-level factors. For state-level factors, a higher odds of lack of preventive dental care was associated with a higher percentage of Medicaid-enrolled children not receiving dental services (OR = 1.30, 95 % confidence interval (CI): 1.15-1.47); higher percentage of children uninsured (OR = 1.48, 95 % CI: 1.29-1.69); lower dentist-to-population ratio (OR = 1.36, 95 % CI: 1.03-1.80); and lower percentage of dentists submitting Medicaid/State Children's Health Insurance Program claims (OR = 1.04, 95 % CI: 1.01-1.06). IORs for the first three state-level factors did not contain one, indicating that these state-level characteristics were important in understanding variation across states. Lack of preventive dental care varied by state (MOR = 1.40). The state-level variation (ICC = 3.66 %) accounted for a small percentage of child- and state-level variation combined. Child- and state-level characteristics were associated with preventive dental care access among U.S. children aged 5-17 years. State-level factors contribute to variation in dental care access across states and need to be considered in state-level planning.

Microsporidia as a Potential Threat to the Iberian Lynx (Lynx pardinus).

Lynx pardinus is one of the world's most endangered felines inhabiting the Iberian Peninsula. The present study was performed to identify the presence of microsporidia due to the mortality increase in lynxes. Samples of urine (n = 124), feces (n = 52), and tissues [spleen (n = 13), brain (n = 9), liver (n = 11), and kidney (n = 10)] from 140 lynxes were studied. The determination of microsporidia was evaluated using Weber's chromotrope stain and Real Time-PCR. Of the lynxes analyzed, stains showed 10.48% and 50% positivity in urine and feces samples, respectively. PCR confirmed that 7.69% and 65.38% belonged to microsporidia species. The imprints of the tissues showed positive results in the spleen (38.46%), brain (22.22%), and liver (27.27%), but negative results in the kidneys. PCR confirmed positive microsporidia results in 61.53%, 55.55%, 45.45%, and 50%, respectively. Seroprevalence against Encephalitozoon cuniculi was also studied in 138 serum samples with a positivity of 55.8%. For the first time, the results presented different species of microsporidia in the urine, feces, and tissue samples of Lynx pardinus. The high titers of anti-E. cuniculi antibodies in lynx sera confirmed the presence of microsporidia in the lynx environment. New studies are needed to establish the impact of microsporidia infection on the survival of the Iberian lynx.
