The first report on the incidence of moderate and severe OHSS in China

Moderate and severe ovarian hyperstimulation syndrome (OHSS) developed in 1.14% of Chinese women of reproductive age between 2013 and 2017. Moreover, women under 35 years of age receiving assisted reproductive technology (ART) should be monitored for OHSS more closely compared with other age groups.
These findings were concluded from the first report on the incidence of moderate and severe OHSS in China recently published in Health Data Science, a Science Partner Journal.
OHSS constitutes the most severe iatrogenic complication of ovulation induction in ART, whose incidence represents ART risk. However, its incidence had been poorly known in China until the Peking University Third Hospital (PUTH) team threw light on the issue.
‘Our purpose is to characterize the incidence of moderate and severe OHSS among Chinese women. It is the first national report of the Chinese population,’ shared Jie Qiao, Academician of the Chinese Academy of Engineering and Professor at PUTH. ‘We believe our findings are very helpful for front-line clinicians to better understand the burden of OHSS.’
‘The national datasets Hospital Quality Monitoring System (HQMS) and National ART Management Information System (NARTMIS) were used to investigate the incidence of moderated and severe OHSS in China,’ said Xiaoyu Long, Associate Professor at PUTH. ‘We also reported the annual incidence by the calendar year in China between 2013 and 2017.’
‘We reported the incidence of moderate and severe OHSS among Chinese women of productive age as 1.14% from 2013 to 2017. The annual incidence trended towards decline during the study period,’ explained Danni Zheng, Management research assistant at PUTH. ‘Women aged 26-30 years and 31-35 years accounted for about 80% of new OHSS cases during this period, suggesting that women aged 26-35 years were at high risk of OHSS.’
The incidence of moderate and severe OHSS and the preponderance of women aged 26-35 years revealed in the study were consistent with previous reports. Moreover, the downward trend may have been driven by the application of the standardized protocol, antagonist regimens, and extensive adoption of oocyte cryopreservation.
With the wide application of ART and the presence of related comorbidities, OHSS is a common complication during ovulation induction. Therefore, knowing the disease burden and identifying the high-risk group is indispensable for improving the health outcomes of the women undergoing ART. ‘We plan to investigate these health issues when the data with finer granularity are available,’ commented Prof. Qiao when she projected the future steps of such studies.

Hailey-Hailey disease is a rare, inherited condition characterized by patches of blisters appearing mainly in the skin folds of the arm pits, groin and under the breasts. It is caused by a mutation in the gene that codes for a specific protein involved in the transportation of calcium and manganese ions from the cell cytoplasm and into a sac-like organelle called the Golgi apparatus. Scientists at Tohoku University, together with colleagues in Japan, have uncovered some aspects of this protein's structure that could help researchers understand how it works. The findings, published ...

ChatGPT's impact extends beyond the education sector and is causing significant changes in other areas. The AI language model is recognized for its ability to perform various tasks, including paper writing, translation, coding, and more, all through question-and-answer-based interactions. The AI system relies on deep learning, which requires extensive training to minimize errors, resulting in frequent data transfers between memory and processors. However, traditional digital computer systems' von Neumann architecture separates the storage and computation of information, resulting in increased ...

A research team at POSTECH led by Professor Chulhong Kim (Department of Electrical Engineering, Department of Convergence IT Engineering, and Department of Mechanical Engineering) has compiled the findings from innovative research on contrast-enhanced photoacoustic imaging conducted over the last four years. These findings were recently featured in Chemical Reviews, a highly authoritative journal.
For decades, the scientific community has been investigating the potential of photoacoustic imaging as a biomedical imaging modality. However, despite its enhanced optical contrast and ultrasonic spatiotemporal resolution, photoacoustic imaging faces ...

FINDINGS
MitoQ, a mitochondrial antioxidant that is available to the public as a diet supplement, was found in a mouse study to reverse the detrimental effects that HIV and antiretroviral therapy (ART) have on mitochondria in the brain, heart, aorta, lungs, kidney and liver.
The researchers used a molecular method to measure the ratio of human and murine mitochondrial (mtDNA) to nuclear DNA (ntDNA) ratio, a measure of mitochondrial dysfunction. Reduction in this ratio reflects mitochondrial dysfunction. Compared to uninfected mice, HIV infected mice treated with ART had mitochondrial dysfunction in the human immune cells in the brain, ...

DALLAS, March 24, 2023 — High levels of lipoprotein(a) [Lp(a)] are an independent, predominantly inherited and causal risk factor for cardiovascular disease, the leading cause of death and disability worldwide, according to a recent American Heart Association scientific statement. It is estimated that 1 in 5 Americans have high Lp(a) levels. Studies have shown that elevated Lp(a) — a low-density lipoprotein variant containing a protein called apolipoprotein(a) — is a risk factor for atherosclerosis (buildup of fatty material in artery walls) and related ...

As the world faces increasingly extreme and frequent weather events brought on by climate change – such as droughts, floods, heatwaves, and wildfires – critical civic resources such as food, water, and energy will be impacted. Local and regional planners need to anticipate those impacts and evaluate what measures can be taken to prepare.
Now, a multidisciplinary, multi-institutional team of researchers has built a detailed framework to provide guidance to these planners. After two years of in-depth consultation ...

A new study of some 3.6 million surgeries from National Health Service (NHS) databases in England suggests that, in most cases, it will be safe to carry out planned surgery from 2 weeks after a positive COVID test, as long as the patient has recovered – compared to current guidance that recommends delaying surgery for 7 weeks. The study is published in Anaesthesia (a journal of the Association of Anaesthetists) and is by Dr Alwyn Kotzé, University of Leeds, UK and Dr Ciarán McInerney, ...

Access to artificial intelligence and machine learning is rapidly changing technology and product development, leading to more advanced, efficient and personalized applications by leveraging a massive amount of data.
However, the same abilities also are in the hands of bad actors, who use AI to create malware that evades detection by the algorithms widely employed by network security tools. Government agencies, banking institutions, critical infrastructure, and the world’s largest companies and their most used products are increasingly under threat from malware that can evade anti-virus systems, hijack networks, ...
