I know Podcasts are meant to be about true crime, I know, not paps smears and pregnancy! This topic is too important not to soar up the podcast charts! In today's super-fast episode I talk about the Cervical Screening Test (CST) its importance and the facts about CST and pregnancy.*Spoiler alert - it is safe to have a CST when you're pregnant*The benefits of being on top of CST ( the new form of pap smear) far outweigh the uncomfortable bits. In the past five years, the way CST are undertaken have changed so CST is a really good topic to add to your list of questions to ask your GP.For information on how a CST works visit herehttps://www.health.gov.au/initiatives-and-programs/national-cervical-screening-program/getting-a-cervical-screening-test/how-cervical-screening-worksSome extra information from The Royal Australian and New Zealand College of Obstetricians and Gynaecologists https://ranzcog.edu.au/womens-health/patient-information-resources/cervical-screening-in-australiaThis episode is fact-checked and supported by www.familyhq.com.au - thanks Liz and Sarah.For more on the suite set, please visit us at https://www.thesuiteset.com/pages/our-gift-to-you

Health workers at the frontline of fighting terrible rates of cervical cancer among Māori say a new, easier test, will save lives but isn't a one-stop fix. The government will introduce a type of swab to test for the HPV virus which causes 99 percent of cervical cancers. Women can do it themselves and it's hoped it will rein in cases, particularly among Māori women, who are two and a half times more likely to die from the disease. Health correspondent Rowan Quinn reports.

The Newborn Screening Test is a quick, safe and effective way to identify babies at risk of certain serious conditions. Screening is the only way to identify affected babies early as there may be no signs or symptoms of illness at birth. By the time affected babies show symptoms, their development or health may already be impaired. Early diagnosis allows early treatment or management to prevent or reduce complications.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.07.21.214395v1?rss=1 Authors: Milne, A. E., Bianco, R., Poole, K. C., Zhao, S., Billig, A. J., Chait, M. E. Abstract: Online experimental platforms can be used as an alternative, or complement, to lab-based research. However, when conducting auditory experiments via online methods, the researcher has limited control over the participants' listening environment. We offer a new method to probe one aspect of that environment, headphone use. Headphones not only provide better control of sound presentation but can also "shield" the listener from background noise. Here we present a rapid (< 3 minute) headphone screening test based on Huggins Pitch (HP), a perceptual phenomenon that can only be detected when stimuli are presented dichotically. We validate this test using a cohort of "Trusted" online participants who completed the test using both headphones and loudspeakers. The same participants also trialled a widely used headphone test (AP test; Woods et al., 2017). We demonstrate that compared to the AP test, the HP test has a higher selectively for headphone users, rendering it as a compelling alternative to the existing screening method. Overall, the new HP test correctly detects 80% of headphone users and has a false positive rate of 20%. Moreover, we demonstrate that there is little overlap between participants who pass both HP and AP tests over loudspeakers. Therefore, combining the two tests can lower the false positive rate to ~7% (but at the expense of an increased false negative rate). This should be useful in situations where headphone use is particularly critical (e.g. dichotic or spatial manipulations). An implementation of the new test is available with JavaScript and through Gorilla (gorilla.sc). Copy rights belong to original authors. Visit the link for more info

There is no golden standard on preparing a screening test for interpreting students. You are supposed to find your own way. In this article I would like to share my approach. Screening test is a must: For one, not every student can become a simultaneous interpreter. Giving false hopes to young minds will only increase their desperation before your realize it is too late. Second, interpreter trainers are usually professional interpreters and they do not have the time and energy needed […]

Dogs (and cats) having a crisis as a result of hypoadrenocorticism (Addisonian crisis) can be in a life-threatening state and this represents one of the true small animal emergencies. Stabilisation of these patients starts with appropriately aggressive intravenous fluid therapy as the first priority and treatment for clinically significant hyperkalaemia and hypoglycaemia may also be needed very early on. Intravenous glucocorticoids are typically then required to continue stabilisation. In this episode I discuss ten talking points relating to canine hypoadrenocorticism, namely: “The Great Pretender” Likely Genetic Basis Aldosterone may be low in ‘atypical’ cases Hypoglycaemia may be severe Bradycardia is not always present and not just due to hyperkalaemia ACTH stimulation test provides definitive diagnosis Single resting plasma cortisol may be useful for screening – but limited role in emergencies?

Hintergrund: Die konventionelle Weiss-auf-Weiss-Perimetrie zählt zum Goldstandard der Glaukom-Diagnostik. Der Verlust achromatischer Kontrastempfindlichkeit ist aber als sensorischer Ausfall ein Spätsymptom und markiert den Beginn einer lokalen Erblindung. In diversen Studien konnte nachgewiesen werden, dass ein Verlust an chromatischer Kontrastempfindlichkeit im kurzwelligen Bereich des Farbspektrums perimetrischen Gesichtsfelddefekten vorausgehen kann. Eine quantitative Bestimmung peripherer Farbkontrastempfindlichkeit erlaubt der Arden-Computergraphik-Farbtest. Ziel dieser Querschnittsstudie war zum einen, Unterschiede in der peripheren Farbkontrast-Sensitivität zwischen einer größeren Gruppe von Glaukom-Patienten (n=50), sogenannten präperimetrischen Diagnosegruppen (Patienten mit okulärer Hypertension, Patienten mit V.a. Glaukom, n=41) und augengesunden Patienten (n=19) zu finden, und zum anderen die Bestimmung von Zusammenhängen zwischen peripheren Farbkontrast-Verlusten im kurzwelligem Bereich (Tritanachse) und zu diesem Zeitpunkt gegebenenfalls bestehenden Pathologien der Papillenmorphologie. Hierfür wurde sowohl der Mittelwert der Farbkontrastempfindlichkeit der einzelnen Quadranten, als auch die Farbkontrastempfindlichkeit eines einzelnen Quadranten (hier „Field Low Left“) mit den entsprechenden HRT II-Parametern (global oder ein einzelner Sektor) korreliert. Patienten und Methodik: Insgesamt wurden 110 Patienten in die Studie miteingeschlossen, und in die Diagnosegruppen „Glaukom“ (n=50), „V.a. Glaukom“ (n=26), „OCH“ (n=13) und „Augengesund“ (n=21) eingeteilt. Bei allen Patienten wurde eine Messung mit dem HRT II zur Erhebung quantitativer Papillen-Mekmale, und der Arden-Computergraphik-Farbtest durchgeführt. Darüber hinaus erfolgte jeweils eine Gesichtsfelduntersuchung, eine Visusbestimmung, eine allgemeine Anamnese, eine ausführliche Medikamentenanamnese und die Bestimmung der im bisherigen Krankheitsverlauf maximalen Tensiowerte. Die Papillenmorphologie wurde anhand qualitativer Merkmale von einem erfahrenen Untersucher in folgende Gruppen eingeteilt: „glaukomatöser Papillenbefund“, „grenzwertiger Papillenbefund“ und „unauffälliger Papillenbefund“. Nichtparametrische Tests: Im Kruskall-Wallis-Test zeigten die Variablen „Field mean“ und „Field LowL“ einen signifkanten Unterschied (p=0,039 bzw. p=0,023) zwischen den Diagnosegruppen. Im Mann-Whitney-Test erfüllen „Field LowL“-Werte die Kriterien einer Zusammenfassung 66 Signifikanz-Adjustierung und unterscheiden sich zwischen den Diagnosgruppen „Glaukom“ und „Augengesund“ statistisch signifkant (p=0,006). Ergebnisse der bivariaten Korrelation: Sowohl im Gesamtkollektiv, als auch in der Diagnosegruppe „Glaukom“ zeigte der Farbkontrast-Schwellenwert des unteren linken Quadranten („Field LowL“) im Unterschied zum Mittelwert der Farbkontrast-Schwellenwerte der Einzel-Quadranten („Field mean“) die stärkeren und häüfigeren Zusammenhänge zur Papillenmorphologie. In der Gruppe „Glaukom“ zeigte „Field LowL“ statistisch signifikante Zusammenhänge zu den meisten stereometrischen Parametern des HRT II: „cup area“ (r=0,547, p=0,000), „rim area“ (r=0,456, p=0,001), „cup/disc area ratio“ (r=0,525, p=0,000), „rim/disc area ratio“ (r=0,525, p=0,000), „cup volume“ (0,453, p=0,001), „rim volume“ (r=0,409, p=0,003), „height variation contour (r=0,38, p=0,006), „cup shape measure“ (r=0,345, p=0,012), „mean RNFL thickness“ (r=0,404, p=0,004) und „RNFL cross sectional area“ (r=0,381, p=0,006). In den präperimetrischen Diagnosegruppen „V.a. Glaukom“ und „OCH“ konnte nur in der „OCH“-Gruppe ein statistisch hochsignifikanter Zusammenhang (r=0,764, p=0,001) zwischen „Field LowL“ und dem stereometrischen Paramter „height variation contour“ gefunden werden. Ergebnisse der partiellen Korrelation: Bei Konstanthalten des Einflusses der Variable „age“ in der Glaukom-Gruppe zeigt „Field mean“ einen moderaten, statistisch signifikanten Zusammenhang zu den HRT-II-Parametern „height variation contour“ (r=0,348, p=0,008) und „CLM temporal-inferior“ (r=0,371, p=0,005). Bei Herauspartialisieren der Variable „disc area“ konnten alle in der bivariaten Korrelation gefundenen Zusammenhänge beibehalten werden. Bei Konstanthalten des Einflusses der mittleren Defekttiefe der Gesichtsfelduntersuchung („MD in dB“) zeigten sich keine statistisch signifikanten Zusammenhänge. Im Unterschied dazu zeigte der Quadranten-Schwellenwert „Field LowL“ in der Glaukom-Gruppe sowohl bei Konstanthalten des Einflusses des Alters, als auch der Papillengröße, als auch der mittleren Defekttiefe der Gesichtsfeld-Untersuchung statistisch signifikante Zusammenhänge zu allen auch in der Pearson-Korrelation gefundenen stereometrischen HRT-II-Parametern, wobei die Zusammenhangs-Stärke bei Herauspartialisieren von „disc area“ und „MD in dB“ schwächer ausfiel als in der bivariaten Korrelation; bezüglich der Kontrollvariable „MD in dB“ sind es: „cup area“ (r=0,457, p=0,001), „rim area“ (r=0,290, p=0,033), „cup/disc area ratio“ (r=0,419, p=0,003), „rim/disc area ratio“ (r=0,419, p=0,003), „cup volume“ (0,333, p=0,017), „rim volume“ (r=0,319, p=0,021), „height variation contour (r=0,304, p=0,027), „cup shape measure“ (r=0,260, Zusammenfassung 67 p=0,05), „mean RNFL thickness“ (r=0,411, p=0,004) und „RNFL cross sectional area“ (r=0,354, p=0,012). Der in der bivariaten Korrelation in der „OCH“-Gruppe gefundene, starke Zusammenhang zwischen „Field LowL“ und dem stereometrischen Paramter „height variation contour“ zeigte sich auch bei Herauspartialisieren des Alters und der mittlerern Defekttiefe der Gesichtsfeld-Untersuchung: r=0,686, p=0,01 bzw. r=0,794, p=0,002, jedoch nicht bei Herauspartialisieren der Variablen „disc area“ (r=0,001, p=0,499). Der überwiegende Teil der in den präperimetrischen Diagnosegruppen gefundenen Zusammenhänge zeigte sich jedoch statistisch nicht signifikant. Ergebnisse der Regressionsanalyse: Sowohl nichtstereometrische Parameter wie Alter, Augeninnendruck und Ergebnisse der Gesichtsfelduntersuchung, als auch die stereometrischen Parameter des Heidelberg-Retina-Tomographen-II zeigen einen statistisch signifikanten Einfluss auf die Ergebnisse des Computergraphik-Farbtests. Während der Einfluss von nichtstereometrischen Parametern einen stärkeren Einfluss auf die Variable „Field mean“ als auf die Variable „Field LowL“ aufweist (r2=0,445, p=0,000 versus r2=0,359, p=0,001), verhält es sich mit den stereometrischen HRT-II-Parametern umgekehrt: Sie zeigen den stärkeren Einfluss auf die Variable „Field LowL“ (r2=0,603, p=0,000 versus r2=0,188, p=0,048). Schlussfolgerung: Die Diagnose „Glaukom“ setzt sich aus den Ergebnissen unterschiedlicher Untersuchungen zusammen. Zu den Eckpfeilern der Glaukom-Diagnostik zählen Papillenveränderungen, erhöhter Augeninnendruck, Gesichtsfelddefekte und schließlich das Alter und die Familienanamnese eines Patienten. In den letzten Jahrzehnten hielt vor allem die qualitative Messung der Papillenmorphologie und umgebender Netzhaut-Strukturen (HRT, OCT, GDX, u.a.) Einzug in die Glaukom-Diagnostik. Gemeinsam mit psychophysikalischen Tests, die Gesichtfelddefekte nachweislich vor dem Verlust an Kontrastempfindlichkeit in der Weiss-auf-Weiss-Perimetrie aufzeigen, erweitert und ergänzt sie die klassische Glaukom-Diagnostik. In dieser Arbeit konnte zunächst bestätigt werden, dass sich die Ergebnisse des Arden-Computergraphik-Farbtests bei einer erstmals großen Gruppe von Glaukom-Patienten signifikant von den Ergebnissen der Kontrollgruppe augengesunder Patienten unterscheiden. Im weiteren konnte erstmals gezeigt werden, dass auch unter Berücksichtigung des Alters und der Ergebnisse der Gesichtsfelduntersuchung ein überwiegend hochsignifikanter Zusammenhang zwischen einem funktionellen Test (Arden- Computergraphik-Farbtest) und einem modernen, rein morphologischen Test (HRT II) bei Glaukompatienten besteht. Die Einzel-Quadranten-Analyse (hier der funktionell linke untere Zusammenfassung 68 Quadrant) zeigte hier die stärksten Zusammanhänge zu den Parametern „cup area“, „rim area“, cup/disc area ratio“ und „rim/disc area ratio“ und ist dem Mittelwert der Schwellenwerte aller Quadranten überlegen. Die statistisch signifikanten Veränderungen entsprechen dem temporal-superioren Bereich der Papille, in dem in frühen und in mäßig fortgeschrittenen Glaukom-Stadien erste Verluste des neuroretinalen Randsaums zu beschrieben sind (Tuulonen A & Airaksinen PJ, 1991, Jonas JB et al., 1993). Dem Arden-Computergraphik-Farbtest kommt somit ein hoher Stellenwert in der Glaukomdiagnostik zu. Die Kombination von Funktion und Morphologie erhöht die Validität in der Glaukomdiagnostik; eine Eignung als Screening-Test, der zwischen präperimetrischen Diagnosegruppen unterscheidet, konnte allerdings nicht bestätigt werden.
Today's podcast presents a review of a psychological study of a simple screening test for Autism that can be used with infants of 12 months of age. The study presents correlational data that can be helpful for pediatricians and parents to use with infants at 12 months of age. The test is simple and harmless, but it cannot be used to defintely prove whether a child has Autism.

Die Glykogen-Speicherkrankheit (GSD) ist eine seltene Stoffwechselerkrankung, die in verschiedenen Ausprägungen (Typen) vorkommt. Im ersten Teil der Arbeit wird durch Messung der Enzymaktivität von saurer α-Glukosidase und der Enzymaktivität des Branchingenzyms ein Screening-Test durchgeführt. Im zweiten Teil wird durch Genanalyse als diagnostische Methode die Erklärung der Erkrankung auf molekulargenetischer Ebene erforscht, um den Zusammenhang zwischen dem Geno- und Phenotyp zu verstehen.
