An environmental analysis of public UAP sightings and sky view potential.

Sightings of unidentified flying objects (UFOs) or unidentified anomalous phenomena (UAP) have been reported throughout history. Given the potential security and safety risks they pose, as well as scientific curiosity, there is increasing interest in understanding what these sighting reports represent. We approach this problem as an important one of the human experience and that can be examined through a geographical lens: what local factors may increase or decrease the number of sighting reports? Using a Bayesian regression method, we test hypotheses based on variables representing sky view potential (light pollution, tree canopy, and cloud cover) and the potential for objects to be present in the sky (aircraft and military installations). The dependent variable includes over 98,000 publicly reported UAP sightings in the conterminous United States during the 20-year period from 2001 to 2020. The model results find credible correlations between variables that suggest people see more "phenomena" when they have more opportunity to. This analysis is one of few investigations of UAP sighting reports at a national scale providing context to help examine individual reports. Given that these objects are labeled unidentifiable in the personal sense, there are many natural and/or human based explanations worth exploring.

Andersen-Tawil syndrome: Overlapping clinical features with Noonan syndrome?

Andersen-Tawil syndrome (ATS) and Noonan syndrome (NS) are both autosomal dominantly inherited disorders that share anomalies in the same body systems, i.e. cardiovascular system, skeleton, growth, and face morphology. Here we report a patient meeting clinical diagnostic criteria for NS in whom no variant in one of the genes known to cause NS was found and a pathogenic variant in KCNJ2 (c.653G > C, p.(Arg218Pro)) was demonstrated. Because of manifestations typical for NS and previously not described in ATS (broad neck, low hairline and pectus excavatum), this may indicate there is a phenotypical overlap between ATS and NS, although we cannot exclude that the patient has an additional, hitherto undetected variant in another gene that explains the NS features. Further studies into a functional relation between KCNJ2 and the RAS/MAPK pathway are needed to determine this further.

Tissue Lesions Due to Spirorchiid Eggs in a Loggerhead Turtle ( Caretta caretta Linnaeus 1758) from Brazil: First Report Outside of the United States.

Spirorchiids (family Spirorchiidae Stunkard 1921) are a group of flukes that inhabit the circulatory system of turtles. Infection by members of the family Spirorchiidae involves egg deposition in the host bloodstream and accumulation in tissues, which cause inflammatory reactions and embolisms, leading or contributing to the death of the host. Reports of spirorchiid egg lesions in loggerhead turtles ( Caretta caretta Linnaeus, 1758) have only been reported from U.S. hosts. In the present report a female loggerhead sea turtle was found dead on the beach in the north part of the State of Rio de Janeiro, Brazil. During gross necropsy, no parasite egg nodule was found. But the microscopic analysis revealed a mild granulomatous inflammatory process due to eggs from the family Spirorchiidae and both Langhans giant cells and foreign-body giant cells in the heart, kidneys, intestines, lungs, and spleen. The present note is the first record of tissue lesions due to spirorchiid eggs in a loggerhead sea turtle outside the United States.

Histopathological findings in lungs of hawksbill turtles collected on the coasts of the states of Espírito Santo and Rio de Janeiro, Brazil / Achados histopatológicos em pulmões de tartarugas-de-pente procedentes dos litorais dos estados do Espírito Santo e do Rio de Janeiro, Brasil

The present work aimed to report the histopathological findings verified in lungs of hawksbill turtles (Eretmochelys imbricata) retrieved from the coasts of the states of Espírito Santo and Rio de Janeiro, Brazil. Between the years 2010 and 2014, 29 E. imbricata individuals were found stranded on the coasts, already dead or dying during treatment. Lung samples of all specimens were collected during necropsies, fixed in 10% neutral buffered formalin, subjected to routine histological processing and classified histomorphologically. The findings revealed that 37.93% of the specimens presented lung lesions. Of these, 90.91% were rescued alive and 9.09% were found dead; 63.63% were females and 36.37% were males. The mean weight was 5.44 Kg and the mean length 39 cm, characterizing young individuals. The animals originated from São Francisco de Itabapoana - RJ, Aracruz - ES, São Mateus - ES, Guarapari - ES, Linhares - ES, Itapemirim - ES, and Anchieta - ES. Macroscopic analysis revealed presence of foam, hyperemia, nodules in the parenchyma, cyst and caseous material. Microscopic examination evidenced heterophilic bronchopneumonia, parasitic granulomatous pneumonia caused by spirorchiids, bacterial granulomatous pneumonia, fungal granulomatous pneumonia, and congestion. It was concluded that juvenile specimens of Eretmochelys imbricata, females and males, originated from the states of Espírito Santo and Rio de Janeiro and found stranded both alive or dead, have significant lung lesions, mainly inflammatory ones, associated or not with infectious agents.(AU)

Objetivou-se com este trabalho relatar os achados histopatológicos em pulmões de Eretmochelys imbricata provenientes dos litorais dos estados do Espírito Santo e do Rio de Janeiro, Brasil. Amostras de pulmões de 29 E. imbricata foram coletadas, durante os anos de 2010 a 2014, em necropsias de espécimes encalhadas mortas ou que vieram a óbito durante o tratamento, nos litorais dos estados do Espírito Santo e do Rio de Janeiro, fixadas em formalina tamponada neutra a 10%, submetidas ao processamento histológico de rotina e classificadas histomorfologicamente. Os dados dos animais mostraram que 37,93% dos animais apresentaram lesões pulmonares. Destes, 90,91% foram encontrados vivos e 9,09% morto, 63,63% eram fêmeas e 36,37% machos. O peso médio foi de 5,44kg, e o comprimento médio de 39cm, o que caracterizou animais juvenis. Os animais eram provenientes de São Francisco de Itabapoana - RJ, Aracruz - ES, São Mateus - ES, Guarapari - ES, Linhares - ES, Itapemirim - ES e Anchieta - ES. Á macroscopia, observou-se: presença de espuma, hiperemia, nódulos no parênquima, cisto e cáseo. Ao exame microscópico, foram encontrados broncopneumonia heterofílica, pneumonia granulomatosa parasitária, causadas por espirorquídeos, pneumonia granulomatosa bacteriana, pneumonia granulomatosa fúngica e congestão. Conclui-se que exemplares juvenis de Eretmochelys imbricata, fêmeas e machos, provenientes dos estados do Espírito Santo e do Rio de Janeiro e encalhados tanto vivos quanto mortos, apresentam lesões pulmonares importantes, principalmente as de origem inflamatória, associadas ou não a agentes infecciosos.(AU)

Spirorchiid Infection in Olive Ridley Turtle, Lepidochelys olivacea (Eschscholtz, 1829) (Testudines: Cheloniidae), from Brazil.

The Olive Ridley turtle, Lepidochelys olivacea (Eschscholtz, 1829) (Testudines: Cheloniidae), is 1 of the 5 species of sea turtle found along the coast of Brazil. Little is known regarding infection by species of the family Spirorchiidae in the host, as only 1 report exists. This case report describes granulomas in different tissues associated to type 1 and 3 spirorchiid eggs in 5 L. olivacea from the Brazilian coast. The occurrence of the eggs was considered an incidental finding and may have contributed to the debility and death of the hosts. This is the second report of tissue lesions due to spirorchids eggs in this host and the first occurrence in Olive Ridley turtle from the Brazilian coast.

Sobrecarga del agente de cuidado dependiente y su relación con la dependencia funcional del adulto mayor / Overload in the dependent care agent and its relation to the elder adult functional dependency

Métodos: Estudio descriptivo, correlacional, transversal, muestreo por conveniencia, incluyó a 90 adultos mayores y 90 agentes de cuidado dependiente. Se describió el perfil socio demográfico, se aplicó el índice de Barthel para evaluar el nivel de dependencia del adulto mayor y la entrevista de Zarit para evaluar la sobrecarga subjetiva del agente de cuidado dependiente. Objetivo: Identificar la relación entre el nivel de sobrecarga subjetiva del agente de cuidado dependiente y el nivel de dependencia funcional del adulto mayor con enfermedad crónico degenerativa en el Hospital General de Silao, Guanajuato en México. Resultados: La edad promedio de los adultos mayores fue de 70.9 ±10, en el índice de Barthel presentaron dependencia leve (41.1%) en las actividades de la vida diaria. El perfil del agente de cuidado dependiente correspondió a una mujer de edad media (53.8 ±5.2), casada (88.9%), ama de casa (73.3%), hija de quien cuida (48.9%). En la entrevista de Zarit se encontró a agentes de cuidado dependiente sin sobrecarga (85.6%). Para verificar si existía correlación entre las variables sobrecarga subjetiva y dependencia funcional, se obtuvo el coeficiente de correlación rho de Spearman (-0.46), p<0.05. Discusión: Orem infirió que en situaciones donde se requiera de cuidado, la sobrecarga del agente de cuidado dependiente se relaciona con la dependencia funcional del adulto mayor. Conclusión: A menor grado de dependencia del adulto mayor, menor es el nivel de sobrecarga subjetiva del agente de cuidado dependiente.

Objective: To identify the relationship between the subjective overload level of the dependent care agent and the functional dependency level of the elder adult suffering from chronic degenerative illnesses at the Silao General Hospital in Guanajuato, Mexico. Methods: A descriptive, correlational, transversal and basic study design was used. Sampling was by convenience, and included 90 elder adults and 90 dependent care agents. The social and demographic profile was described. The Barthel index was used to assess the level of dependence of the elder adult, while the Zarit interview was used to assess the subjective overload of the dependent care agent. Results: The elder adult average age was 70.9 ±10; and after using the Barthel index, 41.1% showed dependency in their daily life. The profile of the dependent care agent corresponded to that of a middle aged woman (53.8 ±5.2), married (88.9%), housewife (73.3%), and daughter of the elder (48.9%). From the Zarit interview, it was found that 85.6% were dependent care agents without overload. In order to verify if a correlation existed between the variables subjective overload and functional dependency, the Spearman correlation rho was calculated, and turned out to be -0.46, p<.05. Discussion: Orem inferred that in situations where healthcare is required, the dependent care agent overload is related to the functional dependency of the elder adult. Conclusions: The lower the grade of dependence of the elder adult, the lower the subjective overload of the dependent care agent.

Efficacy of folic acid when added to statin therapy in patients with hypercholesterolemia following acute myocardial infarction: a randomised pilot trial.

BACKGROUND: Folic acid is assumed to have favourable effects on vascular endothelium, directly as well as indirectly through its effect on homocysteine metabolism. However, the clinical value of folic acid in secondary prevention after acute myocardial infarction (MI) has never been tested. Thus, a randomised, open-label, multicentre trial was performed in order to study the effect of folic acid 5 mg o.d. when added to statin therapy on the incidence of recurrent major clinical events up to 1 year post-MI. METHODS: A total of 283 patients with a total cholesterol >6.5 mmol/l (251 mg/dl) (mean 7.3 mmol/l) were included. All patients received 40 fluvastatin. In 140 of the 283 patients, folic acid (5 mg o.d.) was instituted at discharge, and the remaining 143 patients served as controls. Other secondary prevention measures for both groups were advocated. The primary endpoint was a composite consisting of all vascular events, including death, recurrent MI, strokes, and unplanned invasive coronary interventions. RESULTS: At baseline, the two groups were well-matched for all clinical and demographic parameters. After 1 year of treatment, no difference was noticed in the primary endpoint between the two groups. These endpoints occurred in 43 patients (31%) in the folic acid group, as opposed to 45 patients (31%) in the control group. All separate cardiovascular events were also equally distributed between both groups. Total cholesterol levels decreased to a similar extent in the two groups (to 5.5 and 5.7 mmol/l, in folic acid and control groups, respectively). CONCLUSIONS: In this medium-size pilot study, folic acid did not demonstrate any beneficial additive effects on cardiovascular mortality or morbidity in post-MI patients with hypercholesterolemia who were treated with statin therapy. Larger trials, possibly targeting at selected populations, must be awaited before definitive conclusions regarding the potentially favourable effects of folic acid supplementation in secondary prevention can be drawn.

Effect of fluvastatin on ischaemia following acute myocardial infarction: a randomized trial.

AIMS: Residual ischaemia following acute myocardial infarction (AMI) is related to an adverse outcome, although the effect of early initiation of statin therapy is unknown. METHODS: A randomized, placebo-controlled, double-blind, parallel study was performed, which compared fluvastatin 80 mg daily with placebo in patients with an AMI and total cholesterol of <6.5 mmol.l(-1). Ischaemia was measured by ambulatory electrocardiographic (AECG) monitoring over 48-h at baseline, after 6 weeks and at 12 months. RESULTS: Five hundred and forty patients were included (83% male, age 61+/-11 years); 43% had an anterior AMI and 50% were treated with fibrinolytics in the acute phase. After 12 months, the total cholesterol (TC) level was reduced by 13% and LDL-C (low-density-lipoprotein cholesterol) by 21% (from 3.5 mmol.l(-1) to 2.7 mmol.l(-1)) in the fluvastatin treatment group. Both TC and LDL increased by 9% in the placebo group (P<0.001 between groups). At baseline, ischaemia on AECG was present in only 11% of patients, and absent in 77%; in the remaining 11%, recordings were technically inadequate. After 6 weeks, 32/48 (67%), and 12 months 35/46 (76%) of the patients with ischaemia on the baseline AECG, no longer showed signs of ischaemia. Nevertheless, ischaemia at baseline was predictive for the occurrence of any major clinical event (RR=2.35; 95% CI 1.39-3.2;P <0.001). Fluvastatin treatment did not affect ischaemia on AECG, nor the occurrence of any major clinical events as compared to placebo. Post-hoc analysis in patients with the most pronounced ischaemia at baseline showed a trend for a beneficial effect of fluvastatin on major clinical events (P=0.084). CONCLUSION: Residual ischaemia after AMI is observed less frequently in the present study, than in earlier studies, although it is predictive for future cardiovascular events. As a result, the present study was underpowered, and no effect of fluvastatin on AECG ischaemia, or major clinical events in the first year after AMI, could be detected. The present data do not confirm other reports which support widespread use of statin treatment early after AMI.

Reliability of reporting self-measured blood pressure values by hypertensive patients.

For self-measurement of blood pressure to be useful, patient reporting of test results must be reliable and accurate. Until now no study directly measured the accuracy and reliability of patients' reporting of self-measured blood pressure values. Thirty hypertensive patients (69 +/- 11 years) were instructed to measure blood pressure at home over 14 days with the highly accurate Omron IC monitor and to keep a record of all readings in a patient logbook. To assess the reliability of the records, patients were not informed about the memory capacity of the device. We compared automatically stored blood pressure readings with the respective logbook entries to analyze deletion (under-reporting), addition (over-reporting), and precision of reporting of test results. The prevalent pattern was under-reporting, averaging 36% +/- 24% (3% to 89%), which occurred significantly more than over-reporting (9% +/- 11%; 0% to 38%). The precision of reporting (identical values at corresponding times) was 76% +/- 34% (0% to 100%). This observer error did not affect group comparisons of automatically stored values and logbook entries, although the estimated limits of agreement were wide. Blood pressure control, duration of hypertension, age, or previous use of self-measurement and patterns of logbook entries were not found to be predictive of the patients' reliability. Our results demonstrate a substantial observer error in the reporting of self-measured blood pressure values. This bias may be reduced by memory-equipped blood pressure devices.

[The foundations and objectives of a health campaign: the fight against cancer in Catalonia before the Civil War]. / Fundamento y objetivos de una campaña sanitaria: la lucha anticancerosa en Cataluña anterior a la aguerra civil.

In this article we shall analyse the configuration of the process through which cancer ist characterised as a social problem during the first third of this century, taking Catalonia as an example. We shall study both the scientific aspects of this process as well as the socio-economic and ideological ones, and shall analyse the birth and crisis of some of the institutional projects which were cut short by the war.
