METHODS: A systematic review and meta-analysis was conducted. Studies reporting on randomized clinical trials concerning prolongating hormonal therapy with AIs as compared to a placebo or no prolongation, after an initial five years of hormonal therapy, were eligible. RESULTS: Seven clinical trials were included...

Accurate DNA replication and transcription elongation are crucial for preventing the accumulation of unreplicated DNA and genomic instability. Cells have evolved multiple mechanisms to deal with impaired replication fork progression, challenged by both intrinsic and extrinsic impediments. The bacterium Bacillus subtilis, which adopts multiple forms of differentiation and development, serves as an excellent model system for studying the pathways required to cope with replication stress to preserve genomic stability...

The risks of Zinc oxide nanoparticles (ZnO NPs) applications in biological medicine, food processing industry, agricultural production and the biotoxicity brought by environmental invasion of ZnO NPs both gradually troubled the public due to the lack of research on detoxification strategies. TFEB-regulated autophagy-pyroptosis pathways were found as the crux of the hepatotoxicity induced by ZnO NPs in our latest study. Here, our study served as a connecting link between preceding toxic target and the following protection mechanism of Paeoniflorin (PF)...

Propofol is one of the most used intravenous anesthetic agents, which is widely used in clinical anesthesia induction and maintenance of pediatric patients. Exposure of the developing brain to propofol has been reported to lead to adverse brain changes, which in turn can induce persistent behavioral abnormalities in adulthood. However, the mechanisms by which propofol exposure in the developing brain induces cognitive impairment remain unclear. Here we report that repeated propofol exposure during the second postnatal week impairs spatial learning and memory in young mice...

Retinal gene therapies have shown tremendous progress in the past decade, but the sheer number of disease-causing mutations makes their applicability challenging. In this study we test our hypothesis that retinitis pigmentosa-associated retinal degeneration can be prevented through AMP-activated protein kinase (AMPK)-associated metabolic pathway reprogramming using a gene-independent model of degeneration and rescue. We show that recue of photoreceptor structure and function is not achieved through our model of metabolic reprogramming...

BACKGROUND: Preoperative neoadjuvant chemotherapy plays a critical role in multidisciplinary therapy for a variety of malignant tumours. Although oncologists consider myocardial injury to be the most concerning side effect of chemotherapy, unique chemotherapy-mediated skeletal muscular damage has received attention recently. CLINICAL FEATURES: We report two unusual cases of postoperative delayed respiratory failure following administration of the recommended sugammadex dosage for patients undergoing lengthy operations with deep neuromuscular blockade (NMB) after neoadjuvant chemotherapy...

Functional neurological disorders (FND), formerly called «conversion hysteria», are still poorly understood diseases that suffer from an outdated, sometimes erroneous and stigmatizing conception on the part of health care teams. Enlightened by historical concepts, we propose a modern reading of FND with the aim of deconstructing preconceived ideas and proposing a global, benevolent and individualized approach.

BACKGROUND/AIMS: Cancer studies suffer from an overestimation of prediction of survival when both recurrence and death are of interest. This longitudinal study aimed to mitigate this problem utilizing a semi-competing risk approach evaluating the factors affecting recurrence and postoperative death in patients with colorectal cancer. MATERIALS AND METHODS: This longitudinal prospective study was conducted in 284 patients with resected colorectal cancer who were referred to the Imam Khomeini Clinic in Hamadan, Iran, during 2001-2017...

Despite progress made over the past decade, women are under-represented in positions of leadership in academic medicine. Women physicians face numerous challenges throughout their careers. Despite achieving leadership positions, women in leadership continue to experience the impact of those challenges. In this review, we describe four misconceptions about women in leadership, along with their impact and recommendations. First, we describe differences between mentorship and sponsorship, as well as their impact on attaining leadership positions...

Pancreatic neuroendocrine tumor (pNET) is the second most common malignant tumors of the pancreas. Multiple endocrine neoplasia 1 ( MEN1 ) is the most frequently mutated gene in pNETs and MEN1-encoded protein, menin, is a scaffold protein that interacts with transcription factors and chromatin-modifying proteins to regulate various signaling pathways. However, the role of MEN1 in lipid metabolism has not been studied in pNETs. In this study, we perform targeted metabolomics analysis and find that MEN1 promotes the generation and oxidation of polyunsaturated fat acids (PUFAs)...

Equiatomic binary phases of copper with rare earth (RE) elements exhibit either primitive cubic (Pm3̄m) or orthorhombic (Pnma) structures and in some cases both. By using density functional theory (DFT), we calculated the enthalpies of formation along the series of RE elements combined equimolarly with copper. For RE from Sc to Lu, the calculated enthalpies of formation fall in the range -49.8 kJ/mol for LuCu to -9.1 kJ/mol for the least thermodynamically stable CeCu. Except NdCu, all the other cubic or orthorhombic compounds exhibit lattice stability...

BACKGROUND: Cervical cancer (CC) is a common gynecological malignancy worldwide. Some patients perform serious resistance after chemotherapy, and long-stranded non-coding RNA MEG3 is reported to be involved in the regulation of chemoresistance in many solid tumors. However, its involvement in cervical adenocarcinoma has not been reported. METHODS: Hela cell lines, cisplatin-resistant cell lines (Hela-CR) and nude mice were used in this study. After MEG3 was overexpressed or knocked down in cells by the lentivirus vector, cell growth was detected by the CCK-8 assay, and cell migration was evaluated using Transwell assay...

BACKGROUND: Over two-thirds of the world's population cannot access surgery when needed. Interventions to address this gap have primarily focused on surgical training and ministry-level surgical planning. However, patients more commonly cite cost-rather than governance or surgeon availability-as their primary access barrier. We undertook a randomized, controlled trial (RCT) to evaluate the effect on compliance with scheduled surgical appointments of addressing this barrier through a cash transfer...

To enhance health and medical facilities, some authorities have recently introduced an emergency special water vehicle known as a 'water ambulance'. This vehicle is distinct for remote areas. To operate the ambulance service, environmental issues and energy resources have become major concerns. This is a scope of research to address the issues. First, the possibility of using solar energy as the sole power source for a vessel is a perfect solution to these issues. Second, solar vessels operate everywhere without polluting the environment...

OBJECTIVES: Caring Contacts are an emerging intervention that aims to reduce distress and suicide risk after acute psychiatric care. This trial aimed to determine whether, during a pandemic, there was any evidence that the mental health benefits and reduction in suicidal ideation (SI) associated with delivering Caring Contacts to recently discharged psychiatric patients were greater than a control communication. The secondary objective was to identify whether the predicted benefits were greater among people living alone or those diagnosed with depression...

The majority of publications report the presence of an 'obesity paradox'...

Introduction: Primary obstetric antiphospholipid syndrome (OAPS) is defined by specific morbidities and/or losses of pregnancy in the presence of persistent antiphospholipid antibodies (aPL). This variant of APS is usually treated during pregnancy and the post-partum period. Data on occurrence of thrombotic event during long term follow-up of OAPS patients is limited. Methods: A multi-centre retrospectively cohort of female patients with primary APS (pAPS) was assembled during 2004-2019. Patients were grouped according to disease presentation as pure OAPS or thrombotic APS (tAPS) for those presenting with thrombosis...

BACKGROUND: Apoptosis resistance is a recognized pathogenetic mechanism in pulmonary hypertension. However, the link between apoptosis signal-regulating kinase-1 (ASK-1) and pulmonary hypertension (PH) is unclear. This study was conducted to elucidate ASK-1 as a potential biomarker in PH. The study aimed to identify the role of ASK-1 in the mechanism of monocrotaline-induced PH in rats. METHODS: Forty adult male Sprague-Dawley rats (body weight: 200-250 g) were randomly divided into five groups (n=8 per group)...
