Purpose Coronavirus disease (COVID-19) has profoundly impacted residency training and education. To date, there has not been any broad assessment of urological surgery residency changes and concerns during the COVID-19 pandemic. Materials and methods The Society of Academic Urologists distributed a questionnaire to urology residency program directors on March 30, 2020 exploring residency programs changes related to the COVID-19 pandemic. Descriptive statistics are presented. A qualitative analysis of free response questions was undertaken. A post hoc analysis of differences related to local COVID-19 incidence is described. Results The survey was distributed to 144 residency programs with 65 responses for a 45% response rate. Reserve staffing had started in 80% of programs. Patient-contact time had decreased significantly from 4.7 to 2.1 days per week (P less then 0.001). Redeployment was reported by 26% of programs. Sixty percent of programs reported concern that residents will not meet case minimums due to COVID-19. Wellness activities centered on increased communication. All programs had begun to use video-conferencing and the majority planned to continue using this. Programs in states with higher incidence of COVID-19 were more likely to report resident redeployment (48% vs 11%, P=0.002) and exposure to COVID-19-positive patients (70% vs 40%, P=0.03) and were less likely to report concerns regarding exposure (78% vs 97%, P=0.02) and personal protective equipment (PPE) availability (62% vs 89%, P=0.02). Conclusions As of April 1, 2020, the COVID-19 pandemic had resulted in significant changes in urology residency programs. These findings inform a rapidly changing landscape and aid in development of best practices.Purpose This systematic review summarizes the biomechanical and functional effects of the effortful swallow in adults with and without dysphagia, highlighting clinical implications and future research needs. Specifically, the effects of the effortful swallow on swallowing physiology, safety, and efficiency were identified, as well as the strengths and limitations of current research. Method Recommendations specified by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses were followed. see more A literature search of three databases and relevant articles cited in the searched studies was performed. Two evaluators independently analyzed the studies for eligibility criteria, and final inclusion of studies was decided by consensus. Evaluators also assessed each study for quality of evidence. Results Twenty-three studies were included in this systematic review. Main findings indicated that the effortful swallow generated greater pressures in the tongue-to-palate, pharynx, upper esophageal sphincter, and esophageal regions. Inconsistent results for hyolaryngeal excursion were reported, as well as for swallowing function. Instructions of the effortful swallow varied greatly across studies. Two of the 23 studies were judged to be of high quality, and the remaining studies were of medium quality based on the quality indicators of this review. Conclusions Biomechanical effects of the effortful swallow included increased pressures in the oral, pharyngeal, and esophageal regions. Future investigations should address the effects of the effortful swallow in individuals with dysphagia and its potential role as a rehabilitative maneuver. Moreover, standardization of the effortful swallow instructions based on its physiological and functional effects is essential.Purpose Our study aimed to analyze the characteristics of content word usage in mother's child-directed speech ( CDS) toward children with autism spectrum disorder compared to mother's CDS toward typically developing children. Method We analyzed the lexical characteristics of CDS of mothers of children with autism (16 dyads) and compared them from a language developmental perspective to mothers of 20 typical children at the same level of expressive language development. Results Results suggest that mothers of children with autism use equal amounts of content words at the same language level, but the content consists of significantly more concrete nouns and active verbs and rarely the use of abstract nouns, stative verbs, adjectives, and adverbs. Conclusion This study suggests that professionals and parents of children with autism should be aware of the importance of varying their language use of content words.Giardia and Cryptosporidium are pathogenic protozoa often present in the environment in their infective form(cysts and oocysts). These parasites are very resistant to disinfection, which makes them important target organisms in environmental quality monitoring and sanitation. Viability assessment provides an interpretation of cell inactivation, and it can be evaluated by membrane integrity as well as enzyme activity, using different staining methods. These are straightforward and adequate to laboratories that lack infrastructure for molecular-based technologies or animal infectivity tests. This study investigated simultaneous staining by a commercial live/dead kit, in order to assess viability of Cryptosporidium parvum oocysts and Giardia muris cysts, comparing it to propidium iodide (PI) incorporation, a common stain applied in viability estimation. Results suggested that, although the central hypothesis of one-panel visualization (α = 0.05) was met, simultaneous staining impaired (oo)cyst detection by immunofluorescence assay (IFA), which was found to be essential to enumeration, as the live/dead test led to poor (oo)cyst labelling or a 10-fold lower recovery when carried out concomitantly to IFA. As for the viability assessment itself, although red dye uptake occurred as expected by dead or weakened organisms, neither live G. muris cysts or C. parvum oocysts present any green fluorescence by esterase metabolism. This may have been caused by low enzyme activity in the infective form and/or wall thickness of these parasites. The results do not exclude the possibility of simultaneous fluorescence staining for protozoa, but it is a starting point for a broader analysis, that may consider, for instance, different incubation conditions.
