Ties That Bind: The Value of Professional Connections to Sell-Side Analysts
Authors: Bradley Daniel , Gokkaya Sinan , Liu Xi 
Published: March 2020

We examine professional connections among executives and analysts formed through overlapping historical employment. Analysts with professional connections to coverage firms have more accurate earnings forecasts and issue more informative buy and sell recommendations. These analysts are more likely to participate, be chosen first, and ask more questions during earnings conference calls and analyst/investor days. Homophily based on gender, age, and ethnicity is orthogonal to professional connections. Brokers attract greater trade commissions on stocks covered by connected analysts. Firms benefit through securing research coverage and invitations to broker-hosted investor conferences emulating from these connections. This paper was accepted by Lauren Cohen, finance.
A prospective cross-sectional survey of UK-based dog owners to explore canine handling intolerances and owner willingness to disclose these to veterinary professionals
Authors: Campbell E , Connor M , Buckley LA 
Published: March 2020

Background: Canine handling intolerances (CHI) can be problematic for veterinary professionals (VPs), particularly when not disclosed by owners. Aims: This study explored apparent prevalence of CHI during veterinary practice visits, owner willingness to disclose intolerances to VPs and their beliefs as to responsibilities for disclosure and risks of non-disclosure. Methods: Using a prospective cross-sectional study design, an online, social media-based survey was distributed, which generated 471 usable responses over 4 months. Results: The majority (60.7%) of dogs had CHI. Most owners (78.1%) would definitely alert VPs to CHI, 90.5% believed it was primarily the owners’ responsibility to disclose, with non-disclosure perceived to make procedures high risk for VPs. Veterinary practices could help prevent CHI, with puppy classes and information on canine body language which respondents also felt could be valuable. Conclusion: With CHI common, owners and VPs have roles to play in prevention, disclosure and management to minimise risk to VPs and ensure all parties’ welfare.

Published: March 2020

Introduction: One of the concerns of painless deliveries is the safety of neonates. This clinical trial study aimed to compare the effects of epidural and spinal anesthesia on the mortality rate of neonates.
Methods: This clinical trial was conducted in Hamadan Hospital in Iran. Ninety women, ages 18 to 45, were randomly assigned to receive epidural or subdural anesthesia. Using a checklist, the following were collected: demographic information, midwifery, hemodynamic status, mothers' pain intensity, and analyses of the baby's umbilical cord blood. The data were analyzed by SPSS version 16 for statistical analysis. Twenty-two of the patients with spinal anesthesia and epidural anesthesia were excluded from the study.
Results: There was no significant difference between the two groups in terms of age, gestational age, parity, and severity of pain before or after anesthesia. The hemodynamic status of the mothers before and during the first postoperative period was in the normal range, except that in the spinal group, a decrease in systolic blood pressure was observed in normal range compared with the epidural anesthesia group. In blood gas analysis, the mean pH, partial pressure of carbon dioxide (PCO2), and bicarbonate (HCO3) did not show significant differences between the two groups (p > 0.05). The only complications were acidosis and epidural anesthesia.
Conclusion: Based on the findings of the present study, both spinal and epidural opioids have no adverse effects on the health of neonates. However, both spinal and epidural opioid are preferred due to fewer changes in the hemodynamic changes in mothers and in umbilical cord blood gas.

AbstractDemodex folliculorum shows a high occurrence in the general population, however, its pathologic relevance is still controversial. In this prospective study, we evaluated the prevalence of D. folliculorum on eyelashes from 8,033 subjects of a university population (including 7,782 students, and 251 academics). Additional information on some risk factors to infection by the mites was evaluated, as well. A prevalence of 1.47% was found, where 118 individuals were positive for D. folliculorum; and, among them, 63 (53.4%) were women and 55 (46.6%) were men. Results showed a negative correlation with the age (r = −0.45), the highest prevalence was found in individuals between 19 and 22 years of age (2.1%, 84 patients). The number of D. folliculorum mites did not differ between the right and left eye; however, the use of cosmetics or facial cream, contact lens, hair removers, were factors present in patients infected with D. folliculorum. Although Demodex prevalence did not increase in line with weight, we found significantly higher prevalence in the 51–60 kg and 71–80 kg weight groups, and a particularly high prevalence in the over 81 kg weight group (2.6%). In conclusion, it was observed that the main population positive to infection consisted of young adults; this is in contrast with the international evidence reporting a high rate of infection in older adults. Besides, our results suggest that items of daily use such as cosmetics, facial cream, eyeliner, glasses, or contact lenses may be some of the main culprits of the infection by D. folliculorum.

Published: March 2020

AbstractStreptococcus suis is an emerging zoonotic human pathogen, which is a causative agent of invasive infections in people who are in close contact with infected pigs or contaminated pork products. It is associated with severe systemic infections, most commonly meningitis and sepsis, which may lead to high rates of morbidity and mortality. Serotype 2 is the most prevalent type in S. suis infections in humans. We have reported a case of a very rapidly proceeding fatal human S. suis infection in a splenectomized, but otherwise immunocompetent patient in Hungary. We would like to highlight the attention for this pathogen for the risk group patients, not only pig breeders, veterinarians, abattoir workers, meat processing and transport workers, butchers and cooks, that those persons who are immunocompromised including those with spleen removed, persons with diabetes mellitus, cancer and alcoholism, are also at greater risk of infection.

Published: March 2020

Antecedentes: Se determinaron las características sociodemográficas y psicosociales de los suicidas y parte de la población que intentó suicidarse en la ciudad de Popayán en el año 2007. La incidencia de suicidio en Colombia ha venido incrementándose desde 1985 cuando era de 3,5 por 100.000 habitantes al año, hasta 1999 que era de 5 por 100.000 habitantes al año. Posteriormente se ha sostenido relativamente estable, en el 2007 la mortalidad por suicidio en Colombia fue de 4.1 por 100.000 habitantes1. En Popayán las tasas por 100.000 habitantes en los últimos cuatro años fueron 15,1, 9,8, 15,6 y 9,8 respectivamente siendo mas altas que las del Departamento del Cauca 4.52. OBJETIVO: Describir el fenómeno del suicidio en la ciudad de Popayán en el año 2007 considerando las dimensiones sociodemográfica y psicológica de los suicidios e intentos suicidas. MÉTODOS: Se realizó un estudio descriptivo comparativo en el cual se tomaron 122 sujetos que intentaron suicidarse y que consultaron al hospital Susana López de Valencia y el total de suicidas de la ciudad de Popayán en el año 2007. La información en el caso de los suicidas fue tomada del certificado de defunción, acta de levantamiento y acta de entrega del cadáver y de un instrumento vigente en el Instituto de Medicina Legal y Ciencias Forenses de la ciudad donde se realiza la necropsia médico legal; el mismo instrumento se utilizó para obtener la información en el caso de intentos suicidas mediante la revisión de historias clínicas de los pacientes que intentaron suicidarse y fueron atendidos en el hospital Susana López de Valencia. El análisis de los datos recolectados se realizó con el paquete estadístico STATA V.10. RESULTADOS: se pudo evidenciar el perfil de los sujetos que se intentaron suicidar, para la ciudad de Popayán: ser mujer, joven procedente de área urbana, con bajo grado de escolaridad, con relación familiar estable, con conflicto en la familia, sin antecedente de enfermedad mental y que utiliza como método la intoxicación. Para el suicidio se definió: ser hombre, joven procedente de área urbana con mayor grado de escolaridad, con relación marital inestable, con conflicto de pareja o económicos y que utiliza como método el ahorcamiento.

Объектами исследования были листья шалфея лекарственного (Salvia officinalis L.) из серии«Зеленая аптека», г. Горячий Ключ, Травы Кавказа. Работа посвящена изучению возможности использования альтернативного способа извлечения, идентификации и определения биологически активных веществ из лекарственных трав под воздействием субкритической экстракции. Целью исследований является компонентный состав биологически активных веществ шалфея лекарственного, образующийся в условиях субкритической экстракции. Субкритическая экстракция биологически активных веществ из шалфея лекарственного (Salvia officinalis L.) проводилась с использованием деионизированной воды и 70% раствора этилового спирта в температурном диапазоне от 100 до 250°С. Хроматографическое определение аналитов в экстракте шалфея лекарственного проводили методом газовой и жидкостной хромато-масс-спектрометрии в сочетании с техникой твердофазного концентрирования. Идентификацию аналитов осуществляли с использованием стандартных образцов и индивидуальных соединений. Проведена оптимизация условий субкритической и твердофазной экстракции компонентов эфирных масел и фенольных соединений из экстракта шалфея лекарственного. Оптимальный выход эфирномасличных компонентов из шалфея лекарственного достигается при 200оС, дальнейшее повышение температуры приводит к деградации исследуемых соединений и снижению эффективности их извлечения. Аналиты переводили в органическую фазу твердофазной экстракцией с использованием сорбентов «Strata C18-E», «Strata X», «Oasis HLB». Эфирномасличные и фенольные компоненты в органической фазе получены при субкритической экстракции в условиях повышенных температуры и давлении. Идентифицированный компонентный состав экстракта, образующийся в условиях субкритической экстракции, существенно отличается от веществ, полученных традиционным гидродистилляционным способом. В составе шалфея лекарственного идентифицированы 52 эфирномасличных соединения. Субкритическая экстракция позволила в отличие от гидродистилляционного способа одновременно извлекать компоненты фенольной природы: коричные кислоты, флавоноиды, антоцианы, а также дитерпеновые химические соединения. Достоинством исследуемого способа является возможность одновременного концентрирования и определения эфирномасличных и фенольных компонентов. Результаты данного исследования представляют несомненный интерес для специалистов в области химии лекарственного растительного сырья.
Электростатическая теория селективности ионообменников
Authors: Шапошник Владимир Алексеевич 
Published: March 2020

Ионообменники являются супрамолекулярными веществами, в которых сочетаются прочныековалентные связи (hard chemistry) со слабыми ионными и водородными связями (soft chemistry).Ионные связи в ионообменниках ослаблены гидратацией противоионов и фиксированных ионов. Во-дородные связи образуются между их гидратными молекулами. Элементарный транспортный актионного обмена заключается в разрыве слабых связей. Задачей настоящей работы было определениетипа связи, определяющей селективность ионообменника.Для определения энергии ионных связей был применён интегральный вид закона Кулона.Используя допущения Полея были рассчитаны энергии электростатического взаимодействия фикси-рованных ионов с противоионами. Установлено, что время удерживания катионов щелочных метал-лов является положительной экспоненциальной функцией энергии энергий электростатического при-тяжения противоионов фиксированными ионами. Коррекция параметров электростатического взаи-модействия ионов была проведена неэмпирическими методами квантовой химии.Для определения общей энергии разрыва связей противоионов с фиксированными ионами(энергии активации) была измерена температурная зависимость электропроводностей ионообменныхмембран контактно-разностным методом. Энергии водородных связей были рассчитаны по разностиэнергий активации и энергий электростатического притяжения противоионов фиксированными иона-ми. В результате было установлено, что энергии элементарного транспортного акта в ионообменни-ках для однозарядных ионов определяются преимущественно водородными связями, а для противо-ионов более высокого числа зарядов кроме водородных связей существенную роль играют ионныесвязи, Основным результатом исследования является доказательство определяющей роли электроста-тического взаимодействия (ионных связей) в избирательности ионообменников.
