Authors: Duan Yunfei , Chen Jing , Yang Yu , Qu Zhen , Lu Yunjie , Sun Donglin
Published: July 2020

Drug resistance of Taxol leads to the treatment failure in hepatocellular carcinoma (HCC). LncRNA HOTAIR have drawn increasing attention in various diseases; its function and mechanism in Taxol-resistance in HCC remain unclear. In the present study, the two Taxol resistant HCC cell lines (HepG2/Taxol and SMMC7721/Taxol) were induced. The qRT-PCR data exhibited that over-expressed HOTAIR as well as low-expressed miR-34a were founded in HepG2/Taxol and SMMC7721/Taxol cells. HOTAIR knockdown suppresses proliferation, invasion and promotes apoptosis of in HepG2/Taxol and SMMC7721/Taxol cells through up-regulating miR-34a by MTT assay, transwell invasion assays and flow cytometry, while down-regulation of miR-34a had an opposite effect on reversing Taxol resistance. Cleaved caspase-3 and Bax were significantly up-regulated by si-HOTAIR transfection, while Bcl-2 level exhibited opposite trend. Besides, HOTAIR knockdown impaired Taxol-resistance in HCC by accommodating Akt phosphorylation and Wnt/β-catenin signaling via interacting with miR-34a. The present study may afford a valuable target for treating Taxol-resistance in HCC.
Stochastic maximum principle, dynamic programming principle, and their relationship for fully coupled forward-backward stochastic controlled systems
Authors: Hu Mingshang , Ji Shaolin , Xue Xiaole
Published: July 2020

Within the framework of viscosity solution, we study the relationship between the maximum principle (MP) from M. Hu, S. Ji and X. Xue [SIAM J. Control Optim.56(2018) 4309–4335] and the dynamic programming principle (DPP) from M. Hu, S. Ji and X. Xue [SIAM J. Control Optim.57(2019) 3911–3938] for a fully coupled forward–backward stochastic controlled system (FBSCS) with a nonconvex control domain. For a fully coupled FBSCS, both the corresponding MP and the corresponding Hamilton–Jacobi–Bellman (HJB) equation combine an algebra equation respectively. With the help of a new decoupling technique, we obtain the desirable estimates for the fully coupled forward–backward variational equations and establish the relationship. Furthermore, for the smooth case, we discover the connection between the derivatives of the solution to the algebra equation and some terms in the first-order and second-order adjoint equations. Finally, we study the local case under the monotonicity conditions as from J. Li and Q. Wei [SIAM J. Control Optim.52(2014) 1622–1662] and Z. Wu [Syst. Sci. Math. Sci.11(1998) 249–259], and obtain the relationship between the MP from Z. Wu [Syst. Sci. Math. Sci.11(1998) 249–259] and the DPP from J. Li and Q. Wei [SIAM J. Control Optim.52(2014) 1622–1662].

Diabetische Nephropathie
Authors: Busch Martin , Wolf Gunter
Published: July 2020

In der deutschen Bevölkerung leiden 8–9 % an Diabetes mellitus. Vor allem die ältere Bevölkerung ist betroffen, häufiger in den neuen Bundesländern. Die Gesamtprävalenz einer Nierenerkrankung bei Diabetikern wird in Deutschland mit 15 % angegeben. Bis zu 40 % der Patienten mit Diabetes mellitus entwickeln im Verlauf eine Nephropathie. Diabetesdauer, höheres Alter, Blutzucker- und Blutdruckeinstellung sind Einflussfaktoren, auch bislang nicht vollständig charakterisierte (poly)genetische Faktoren. Die Verdachtsdiagnose einer diabetischen Nephropathie erfolgt beim Nachweis einer Mikroalbuminurie und/oder anderweitig nicht erklärbarer Einschränkung der geschätzten („estimated“) glomerulären Filtrationsrate (eGFR). Beweisend ist nur eine Nierenbiopsie, die jedoch selten indiziert ist. Andere oder Koentitäten sind dennoch häufig. Zur Prävention und Progressionshemmung einer Nephropathie sollte ein individualisierter HbA1c-Korridor von 6,5–7,5 % angestrebt werden. Basierend auf einer Metformintherapie sind bei Typ-2-Diabetes dann SGLT-2-Hemmer und GLP-1-Agonisten bevorzugt einzusetzen, da sie eigenständige nephro- und kardioprotektive Effekte aufweisen. Typ-1-Diabetiker sind intensiviert mit Insulin zu behandeln. Eine adäquate Blutdruckkontrolle sollte mittels Blockade des Renin-Angiotensin-Systems erfolgen. Gewichtsreduktion, körperliche Aktivität, Beendigung des Rauchens sowie Behandlung einer Dyslipidämie sind weitere Maßnahmen.

Unklar ist, ob in Bezug auf das funktionelle Outcome relevante Unterschiede zwischen beiden Verfahren bestehen.

Material und Methoden Es erfolgte eine postoperative Nachbefragung aller Patienten, bei denen im Zeitraum November 2013 bis November 2018 eine laparoskopische oder roboterassistierte Sigmaresektion bei Divertikulitis durchgeführt wurde, mit einem Mindestabstand von 6 Monaten zur Operation. Es wurden Kontinenzstörungen, die Entwicklung der Beschwerden gegenüber dem präoperativen Zustand, Veränderungen des Stuhlgangs (Obstipation, Diarrhö), Beeinträchtigung im Alltag und Schmerzen erfasst. Unterschiede zwischen den Gruppen wurden anhand des Chi-Quadrat-Tests auf statistische Signifikanzen geprüft.

Ergebnisse Im Untersuchungszeitraum wurden insgesamt 106 minimalinvasive Sigmaresektionen bei Divertikulitis durchgeführt (laparoskopisch: n = 46, roboterassistiert: n = 60). Davon beantworteten 74 Patienten (70%; laparoskopisch: n = 28, roboterassistiert: n = 46) den Fragebogen und wurden in die Auswertung aufgenommen. Kontinenzstörungen wurden in insgesamt 22% der Fälle angegeben. In keiner der abgefragten Variablen ergab sich zwischen den Gruppen ein statistisch signifikanter Unterschied.

Schlussfolgerung In Bezug auf funktionelle Ergebnisse nach minimalinvasiver Sigmaresektion bei Divertikulitis sind die laparoskopische und die roboterassistierte Sigmaresektion als gleichwertige Verfahren anzusehen.

A fratura supracondiliana do úmero representa cerca de 3 a 15% de todas as fraturas na criança, sendo a que mais requer tratamento cirúrgico na população pediátrica. Apesar de os avanços no tratamento e na assistência terem contribuído para uma redução drástica da complicação mais temida, a contratura isquêmica de Volkmann, os riscos inerentes à fratura permanecem. Ausência de pulso palpável em fraturas tipo III é reportada em até 20% dos casos. Uma cuidadosa avaliação sensitiva, motora e vascular do membro acometido é fundamental na determinação da urgência do tratamento. Crianças mais velhas, sexo masculino, cotovelo flutuante, e lesão neurovascular são fatores de risco para a síndrome de compartimento. A cominuição medial pode levar à consolidação em varo, mesmo nos casos aparentemente inocentes. O método de escolha para o tratamento da fratura desviada é a redução fechada e fixação percutânea. Os erros na fixação e posicionamento inadequado dos implantes são as principais causas de perda de redução. Já existem evidências suficientes para a utilização de um terceiro fio de Kirschner, lateral ou medial, nas fraturas instáveis (tipo III e IV). Baseado nos conceitos atuais, um fluxograma para o tratamento da fratura supracondiliana do úmero na criança é sugerido pelos autores.
Estenose degenerativa do canal lombar
Authors: Hennemann Sergio , de Abreu Marcelo Rodrigues
Published: July 2020

A estenose degenerativa do canal vertebral lombar é a causa mais frequente de dor lombar e/ou ciática no paciente idoso; sua epidemiologia, fisiopatogenia, manifestações e testes clínicos são revistos em ampla investigação bibliográfica atual. A importância da relação entre a clínica e o estudo por imagens, principalmente a ressonância magnética (RM), é ressaltada. Antes da indicação do tratamento, é necessário identificar a localização precisa da dor, bem como o diagnóstico diferencial entre a claudicação neurogênica e a vascular. O tratamento conservador associando medicações com as diversas técnicas fisioterápicas resolve o problema na maioria dos casos, já o teste terapêutico com os bloqueios, seja epidural, foraminal ou facetário, é realizado quando as dores não cedem com o tratamento conservador e antes da indicação da cirurgia. Os bloqueios costumam dar melhores resultados no alívio dos sintomas de ciatalgia e menos no quadro de claudicação neurogênica. A descompressão da cauda equina e/ou radicular associada ou não à artrodese é o padrão ouro quando a intervenção cirúrgica é necessária. A artrodese após a descompressão é necessária nos casos com instabilidade segmentar, como na espondilolistese degenerativa. Quando a estenose de canal acontece em múltiplos níveis e vem acompanhada de desvio de eixo, seja coronal e/ou sagital, deve ser realizada, além das descompressões e artrodese, a correção dos desvios de eixo, principalmente o eixo sagital, quando a correção da lordose lombar se impõe com técnicas que corrigem a lordose retificada para valores próximos à incidência pélvica.

Objective This study aimed to compare maternal and neonatal outcomes in women with severe preeclampsia before and after implementation of the American College of Obstetricians and Gynecologists (ACOG) taskforce hypertensive guidelines.

Study Design Single-center retrospective cohort study of women with severe preeclampsia delivering live nonanomalous singletons 23 to 342/7 weeks from 2013 to 2017. In 2015, the ACOG guidelines for expectant management of severe preeclampsia were implemented at our institution. Based on this, patients were categorized as preguideline (January 2013–December 2015) or postguideline adoption (January 2016–December 2017). Primary outcomes included composite maternal morbidity and composite neonatal morbidity; secondary outcomes included composite components, length of stay, birth weight, and delivery gestational age. Groups were compared with Student's t-test, Chi-square, and Wilcoxon's rank-sum tests; adjusted odds ratios (aOR; 95% confidence intervals [CIs]) were calculated. Yearly composite outcomes were compared using the Cochran–Armitage trend test. We estimated a sample size of 250 per group would provide 80% power at α = 0.05 to detect a 50% reduction in neonatal morbidity from a baseline rate of 21.5%.

Results From 2013 to 2017, a total of 543 women with severe preeclampsia were identified: 278 (51%) preguideline and 265 (49%) postguideline. Baseline characteristics were overall similar between groups. There were no significant differences in maternal (aOR = 0.96, 95% CI: 0.6–1.41) or neonatal (aOR = 0.88, 95% CI: 0.61–1.28) composite morbidity between groups. Furthermore, there were no differences in composite maternal or neonatal morbidity over time.

Conclusion Perinatal outcomes were similar before and after implementation of severe preeclampsia management guidelines at our institution. Studies to evaluate if benefits are limited to subsets of this population, such as earlier gestational ages, are needed.

Objective This study aimed to determine the impact of neonatal intensive care unit (NICU) design and environmental factors on neonatal sound exposures. We hypothesized that monitoring with a smartphone application would identify modifiable environmental factors in different NICU design formats.

Study Design Minimum, maximum, and peak decibel (dB) recordings were obtained using the Decibel X phone app, and the presence of noise sources was recorded in each patient space at three NICUs over a 6-month period (December 2017 to May 2018). Data were analyzed by Student's t-test and ANOVA with Bonferroni correction. Data were collected at the University of Maryland Medical Center single family room (SFR) level IV and St. Agnes Healthcare hybrid pod/single family room level III NICU, Baltimore, MD and at Prince George's Hospital Center open-pod design Level III NICU, Cheverly, MD.

Results All recordings in the three NICUs exceeded the American Academy of Pediatrics (AAP) recommended <45 dB level. The maximum and peak dB were highest in the open pod format level III NICU. Conversations/music alone and combined with other factors contributed to increased sound exposure. Sound exposure varied by day/night shift, with higher day exposures at the level III hybrid and open pod NICUs and higher night exposures at the level IV SFR NICU.

Conclusion Although sound exposure varied by NICU design, all recordings exceeded the AAP recommendation due, in part, to potentially modifiable environmental factors. A smartphone application may be useful for auditing NICU sound exposure in quality improvements efforts to minimize environmental sound exposure.
