Massive pulmonary embolism and its treatment with thrombolysis both carry grave risks. Optimal management hinges on determining the risk-to-benefit ratio of thrombolytic administration. For patients with liver dysfunction, assessing bleeding risk is challenging because they may have elevations in the international normalized ratio yet be hypercoagulable. We describe a patient with massive pulmonary embolism and new-onset liver failure, who-absent contraindications-warranted thrombolysis. Initial laboratory values, however, revealed an elevated international normalized ratio, which precluded lysis, despite a hypercoagulable Thromboelastogram. We believe that viscoelastic testing of coagulation is essential for evaluating coagulation in liver dysfunction, particularly when considering thrombolysis.

Iron-Photocatalyzed Decarboxylative Alkylation of Carboxylic Acids with Morita-Baylis-Hillman Acetates.
Org Lett

College of Advanced Interdisciplinary Science and Technology (CAIST), Henan University of Technology, Zhengzhou 450001, Henan, P. R. China.
We present an iron-photocatalyzed decarboxylative alkylation strategy involving carboxylic acids and Morita-Baylis-Hillman (MBH) acetates to synthesize -type tri- and tetrasubstituted alkenes with moderate to excellent stereoselectivity (/ ratio up to >19:1). This method is applicable to a broad range of structurally diverse primary, secondary, and tertiary alkyl carboxylic acids, as well as complex pharmaceutical and natural carboxylic acids, achieving efficient alkylation of various MBH acetates under mild conditions (>60 examples, with yields up to 96%). This approach offers a powerful strategy for streamlined alkylation.

Aim: This study aimed to evaluate the association between serum calcium level and the risk of acute kidney injury (AKI) in patients with subarachnoid hemorrhage (SAH).
Methods: In this retrospective cohort study, data on adults from the Medical Information Mart for Intensive Care (MIMIC-III and MIMIC-IV) databases, spanning from 2008 to 2019, were extracted. In the logistic regression models, confounding variables, including age, white blood cell (WBC), systolic blood pressure (SBP), heart rate, blood urea nitrogen (BUN), glucose, international normalized ratio (INR), and the Charlson Comorbidity Index (CCI), were finally adjusted by stepwise regression.

In preeclampsia, there occurs a defective trophoblastic invasion of spiral arteries, which is characterized by abnormal uterine artery wave parameter such as increased pulsatility index (PI) and early diastolic notch. This increased uterine artery PI is a good predictor of hypertensive disorder and small for gestational-age babies. Maternal hypertension and proteinuria resolve in the puerperium.

Individuals who are at risk of not achieving a full milk supply are often overlooked in scientific literature. There is available guidance to help establish an adequate milk supply for healthy individuals experiencing a physiologic labor and birth, and there are robust recommendations for the lactating parents of small, sick, and preterm newborns to ensure that these newborns can receive human milk. Missing from the literature are clinical practice guidelines that address the preexisting health, pregnancy, birth, or newborn-related risk factors for suboptimal lactation.

Many animals face significant challenges in locating and acquiring resources that are unevenly distributed in space and time. In the case of nonhuman primates, it remains unclear how individuals remember goal locations and whether they navigate using a route-based or a coordinate-based mental representation when moving between out-of-sight feeding and resting sites (i.e.
