Especies de rhabdítidos (Nematoda, Rhabditida) citadas en España peninsular y las Islas Baleares

Previous records of species belonging to the order Rhabditida in peninsular Spain and Balearic Islands is presented as compilation. Eighty species of forty genera and twelve families are listed. Information concerning each species contains scientific name, synonymy, distribution and remarks. Distributional data include localities and/or geographical areas where the species have been collected and the corresponding references.

Does overconfidence pay off when things go well?: CEO overconfidence, firm performance, and the business cycle

We investigate the moderating effect of the business cycle on the positive relationship between CEO overconfidence and firm performance. We propose that the expansion years of the business cycle enhance the positive impact of overconfident CEOs on firms’ performance. However, this effect is reduced during recession periods. We analyze the effect of CEO overconfidence on the Return on Equity of publicly listed US firms from 1992 to 2015, a period that includes the bursting of the dot-com bubble in 2001 and the Great Recession of 2008–2009. The empirical findings support the hypotheses that expansion periods increase the positive relationship between overconfident CEOs and firms’ performance, but this positive effect weakens during recessions.Fil: Reyes, Tomas.

First record of Longidorella xenura and Oriverutus parvus (Nematoda: Nodiidae) in Cuc Phuong national park, Vietnam

Longidorella xenura and Oriverutus parvus from Cuc Phuong National Park are described and illustrated for the first time in Vietnam. Longidorella xenura species is characterized by its small body 0.72 mm long; lip region continuous; odontostyle typical of the genus, slightly arched; odontophore linear, rod-like; female genital system didelphic-amphidelphic; tail conical elongated with finely rounded tip. Oriverutus parvus species is characterized by its body 0.64-0.68 mm long; lip region slightly angular, offset by depression or weak constriction; lips moderately amalgamated with protruding papillae but not typically lobe-like; odontostyle moderately robust; odontophore rod-like; female genital system didelphic-amphidelphic; tail conical with pointed tip.Longidorella xenura and Oriverutus parvus from Cuc Phuong National Park are described and illustrated for the first time in Vietnam.

Updated taxonomy and new insights into the evolutionary relationships of the genus Sporonchulus Cobb, 1917 (Nematoda, Mononchida) after the study of two Vietnamese species

Two known species of the genus Sporonchulus, namely S. ibitiensis and S. vagabundus, collected from natural areas of Vietnam, are characterized, including descriptions and illustrations of both species, as well as SEM observations and molecular (18S-, 28S rDNA) analyses of S. ibitiensis. The identity of the two species is discussed, with detailed comparison with previously known populations. The taxonomy of the genus is updated, presenting a diagnosis, list of species, key to their identification, and a compendium of their main morphometrics. An integrative analysis, combining morphological data with a cladistic approach and the first molecular study for a representative of Sporonchulus, better supports a narrow relationship of this genus with Mononchidae than with Mylonchulidae members, however further research should be conducted to elucidate its phylogeny

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
