Long-term partial response in a patient with liver metastasis of primary adrenocortical carcinoma with adjuvant mitotane plus transcatheter arterial chemoembolization and microwave ablation: a case report.

Adrenocortical carcinoma (ACC) is a rare, heterogeneous, and aggressive malignancy with a generally poor prognosis. Surgical resection is the optimal treatment plan. After surgery, both mitotane treatment or the etoposide-doxorubicin-cisplatin (EDP) protocol plus mitotane chemotherapy have a certain effect, but there is still an extremely high possibility of recurrence and metastasis.

Association between risk variants and the occurrence of sepsis in Black patients hospitalized with infections: a retrospective cohort study.

Background: Two risk variants in the apolipoprotein L1 gene ( ) have been associated with increased susceptibility to sepsis in Black patients. However, it remains unclear whether high-risk genotypes are associated with occurrence of either sepsis or sepsis-related phenotypes in patients hospitalized with infections, independent of their association with pre-existing severe renal disease.

Methods: A retrospective cohort study of 2,242 Black patients hospitalized with infections.

PASS was electrospun into a nanofibrous membrane with an average nanofiber diameter of 0.31 µm and basis weight of 3 g/m.

Association of Fatal and Nonfatal Cardiovascular Outcomes With 24-Hour Mean Arterial Pressure.

Major adverse cardiovascular events are closely associated with 24-hour blood pressure (BP). We determined outcome-driven thresholds for 24-hour mean arterial pressure (MAP), a BP index estimated by oscillometric devices. We assessed the association of major adverse cardiovascular events with 24-hour MAP, systolic BP (SBP), and diastolic BP (DBP) in a population-based cohort (n=11 596).

Treatment of Masked Hypertension with a Chinese Herbal Formula: A Randomized, Placebo-Controlled Trial.

Background: Masked hypertension is associated with adverse cardiovascular outcomes. Nonetheless, no randomized controlled trials exist in the treatment of masked hypertension. The aim of this randomized, placebo-controlled trial was to investigate the efficacy and safety of blood pressure (BP)-lowering treatment with a Chinese herbal formula, gastrodia-uncaria granules, in patients with masked hypertension.

Physiological and Ecological Responses of Photosynthetic Processes to Oceanic Properties and Phytoplankton Communities in the Oligotrophic Western Pacific Ocean.

Understanding the dynamics of primary productivity in a rapidly changing marine environment requires mechanistic insight into the photosynthetic processes (light absorption characteristics and electron transport) in response to the variability of environmental conditions and algal species. Here, we examined the photosynthetic performance and related physiological and ecological responses to oceanic properties [temperature, salinity, light, size-fractionated chlorophyll (Chl ) and nutrients] and phytoplankton communities in the oligotrophic Western Pacific Ocean (WPO). Our results revealed high variability in the maximum (F/F; 0.

Cardiovascular End Points and Mortality Are Not Closer Associated With Central Than Peripheral Pulsatile Blood Pressure Components.

Pulsatile blood pressure (BP) confers cardiovascular risk. Whether associations of cardiovascular end points are tighter for central systolic BP (cSBP) than peripheral systolic BP (pSBP) or central pulse pressure (cPP) than peripheral pulse pressure (pPP) is uncertain. Among 5608 participants (54.

Opposing Age-Related Trends in Absolute and Relative Risk of Adverse Health Outcomes Associated With Out-of-Office Blood Pressure.

Participant-level meta-analyses assessed the age-specific relevance of office blood pressure to cardiovascular complications, but this information is lacking for out-of-office blood pressure. At baseline, daytime ambulatory (n=12 624) or home (n=5297) blood pressure were measured in 17 921 participants (51.3% women; mean age, 54.

Use of Genetic Variants Related to Antihypertensive Drugs to Inform on Efficacy and Side Effects.

Background: Drug effects can be investigated through natural variation in the genes for their protein targets. The present study aimed to use this approach to explore the potential side effects and repurposing potential of antihypertensive drugs, which are among the most commonly used medications worldwide.

Methods: Genetic proxies for the effect of antihypertensive drug classes were identified as variants in the genes for the corresponding targets that associated with systolic blood pressure at genome-wide significance.

Response of gas-exchange characteristics and chlorophyll fluorescence to acute sulfur dioxide exposure in landscape plants.

To explore the toxicity and action mechanism of acute sulfur dioxide (SO) on urban landscape plants, a simulated SO stress environment by using fumigation chamber involving increasing SO concentration (0, 25, 50, 100, 200 mg m) was carried out among three species. After 72 h of exposure, SO-induced oxidative damage indicated by electrolyte leakage increased with higher dose of SO. Meanwhile, SO decreased the contents of chlorophyll a, chlorophyll b and carotenoid and increased the contents of sulfur.

LPA Variants Are Associated With Residual Cardiovascular Risk in Patients Receiving Statins.
