Pan-Asian adapted ESMO Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with endometrial cancer.

The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with endometrial cancer was published in 2022. It was therefore decided, by both the ESMO and the Indian Society of Medical and Paediatric Oncology (ISMPO), to convene a virtual meeting in July 2022 to adapt the ESMO 2022 guidelines to take into account the variations in the management of endometrial cancer in Asia. These guidelines represent the consensus opinion of a panel of Asian experts representing the oncological societies of China (CSCO), India (ISMPO), Indonesia (ISHMO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO). Voting was based on scientific evidence and was conducted independently of the current treatment practices and treatment access constraints in the different Asian countries, which were discussed when appropriate. The aim of this guideline manuscript is to provide guidance for the optimisation and harmonisation of the management of patients with endometrial cancer across the different regions of Asia, drawing on the evidence provided by Western and Asian trials whilst respecting the variations in clinical presentation, diagnostic practices including molecular profiling and disparities in access to therapeutic options, including drug approvals and reimbursement strategies.

Effects of physical fitness training on metabolic syndrome among military personnel in Taiwan.

INTRODUCTION: Metabolic syndrome (MS) is strongly associated with cardiovascular diseases and diabetes but can be prevented with regular physical activity. This study aimed to assess the impact of a physical fitness training programme on MS among military personnel. METHODS: This retrospective observational study included volunteer army soldiers who underwent annual health examinations between 2011 and 2014. In 2011, the reformed physical fitness training programme and physical fitness test were introduced to the participants. MS evaluation and physical fitness performances were evaluated before and after implementing the training programme using a mixed-effects model and generalised estimating equation, adjusted for sex, age and smoking. RESULTS: From 2011 to 2014, 1720 soldiers underwent the annual health examination. In 2011, before the fitness programme, 246 soldiers (14.3%) had MS. After implementation, decreases in blood pressure and fasting glucose levels were observed and maintained for 3 years. Running performance was negatively correlated to triglycerides (ß=-11.37; p<0.001) and waist circumference (ß=-0.42; p<0.001) and positively correlated to high-density lipoprotein cholesterol levels (ß=2.14; p<0.001). The severity of MS was reduced following introduction of the physical fitness programme. CONCLUSIONS: MS and its components improved after introducing the reformed fitness programme, with running performance proving to be most relevant to MS. Clinicians should encourage increased physical activity to prevent MS among military personnel.

Severe myocardial bridge presenting as paroxysmal atrioventricular block.

Chest pain complicated with electrocardiographic changes is not an uncommon scenario in emergency departments, which should be examined cautiously. We describe a 51-years-old man with a myocardial bridge of coronary artery presenting with simultaneous Mobitz type I atrioventricular block on electrocardiography. Echocardiography excluded valvular abnormality and systolic/diastolic dysfunction. Coronary angiography confirmed the diagnosis of a myocardial bridge at the middle segment of the left anterior descending artery, involving the most dominant septal perforator branch with marked systolic compression. The patient underwent coronary artery bypass grafting surgery and was followed up uneventfully at the outpatient department with medical treatment of diltiazem and clopidogrel. The present case is being reported to highlight that clinicians should be alert to such a congenital abnormality as a potential cause of repeated myocardial infarction and conduction abnormality.

Use of Autologous Cord Blood Mononuclear Cells Infusion for the Prevention of Bronchopulmonary Dysplasia in Extremely Preterm Neonates: A Study Protocol for a Placebo-Controlled Randomized Multicenter Trial [NCT03053076].

Background: Despite the rapid advance of neonatal care, bronchopulmonary dysplasia (BPD) remains a significant burden for the preterm population, and there is a lack of effective intervention. Stem cell depletion because of preterm birth is regarded as one of the underlying pathological mechanisms for the arrest of alveolar and vascular development. Preclinical and small-sample clinical studies have proven the efficacy and safety of stem cells in treating and preventing lung injury. However, there are currently no randomized clinical trials (RCTs) investigating the use of autologous cord blood mononuclear cells (ACBMNC) for the prevention of BPD in premature infants. The purpose of this study is to investigate the effects of infusion of ACBMNC for the prevention of BPD in preterm neonates <28 weeks. Methods: In this prospective, randomized controlled double-blind multi-center clinical trial, 200 preterm neonates <28 weeks gestation will be randomly assigned to receive intravenous ACBMNC infusion (5 × 107 cells/kg) or placebo (normal saline) within 24 h after birth in a 1:1 ratio using a central randomization system. The primary outcome will be survival without BPD at 36 weeks of postmenstrual age or at discharge, whichever comes first. The secondary outcomes will include the mortality rate, other common preterm complication rates, respiratory support duration, length, and cost of hospitalization, and long-term outcomes after a 2-year follow-up. Conclusion: This will be the first randomized, controlled, blinded trial to evaluate the efficacy of ACBMNC infusion as a prevention therapy for BPD. The results of this trial will provide valuable clinical evidence for recommendations on the management of BPD in extremely preterm infants.

Orally administered resveratrol enhances the therapeutic effect of autologous transplanted adipose-derived stem cells on rats with diabetic hepatopathy.

Stem cell therapy is a promising treatment for hepatopathy due to diabetes mellitus (DM); oral resveratrol treatment exhibits protective effects. We investigated whether protective effects could be produced in liver of diabetic rats receiving autologous adipose-derived stem cell transplantation (ADSC) plus oral resveratrol administration. Male rats were divided into four groups: sham group; streptozotocin induced DM group; DM + ADSC group, in which DM rats were treated with 106 stem cells/rat; and DM + R + ADSC group, in which DM rats were treated with ADSC and oral resveratrol. The DM group exhibited apoptosis, inflammation and fibrosis, whereas Sirt-1 and survival signaling were suppressed. Pathological conditions other than survival signaling were improved in the DM + ADSC group. All pathological conditions were improved in the DM + R + ADSC group. Also, the oxidative stress level in the blood was reduced in the DM + R + ADSC group compared to the sham group. Oral resveratrol administration appears to reduce oxidative damage and enhances survival signaling in diabetic liver. The therapeutic response in the DM + R + ADSC group was better than in the DM + ADSC group.

The effect of orbital-lattice coupling on the electrical resistivity of YBaCuFeO5 investigated by X-ray absorption.

Temperature-dependent X-ray absorption near-edge structures, X-ray linear dichroism (XLD) and extended X-ray absorption fine structure (EXAFS) spectroscopic techniques were used to investigate the valence state, preferred orbital and local atomic structure that significantly affect the electrical and magnetic properties of a single crystal of YBaCuFeO5 (YBCFO). An onset of increase of resistivity at ~180 K, followed by a rapid increase at/below 125 K, is observed. An antiferromagnetic (AFM)-like transition is close to the temperature at which the resistivity starts to increase in the ab-plane and is also observed with strong anisotropy between the ab-plane and the c-axis. The XLD spectra at the Fe L3,2-edge revealed a change in Fe 3d eg holes from the preferential [Formula: see text] orbital at high temperature (300-150 K) to the [Formula: see text] orbital at/below 125 K. The analysis of the Fe K-edge EXAFS data of YBCFO further revealed an unusual increase in the Debye-Waller factor of the nearest-neighbor Fe-O bond length at/below 125 K, suggesting phonon-softening behavior, resulting in the breaking of lattice symmetry, particularly in the ab-plane of Fe-related square pyramids. These findings demonstrate a close correlation between electrical resistivity and coupling of the preferred Fe 3d orbital with lattice distortion of a single crystal of YBCFO.

C-terminus of Hsc70-interacting protein (CHIP) enhances stemness properties of human Wharton's jelly mesenchymal stem cell.

Mesenchymal stem cells are an attractive source of multipotent cells in part because they are easy to obtain. Several E3 ligases regulate the stability and functions of various factors in different adult stem cells through the ubiquitylation pathway. We investigated the C-terminus of Hsc70-interacting protein (CHIP) E3 ligase that regulates pluripotency of human Wharton's jelly mesenchymal stem cells (hWJMSC). We found that CHIP increases protein kinase B (Akt) phosphorylation by decreased expression of phosphatase and tensin homolog (PTEN), which suggests improvement of the survival pathway by CHIP over-expression. We also found that increased CHIP expression induced Sox2 and NANOG, which can promote stem cell self-renewal and prevent oxidative stress-induced senescence of hWJMSC by decreased p21. We found that CHIP could be used to enhance the multiple functions of hWJMSC.

Collaborations in gynecologic oncology education and research in low- and middle- income countries: Current status, barriers and opportunities.

Eighty-five percent of the incidents and deaths from cervical cancer occur in low and middle income countries. In many of these countries, this is the most common cancer in women. The survivals of the women with gynecologic cancers are hampered by the paucity of prevention, screening, treatment facilities and gynecologic oncology providers. Increasing efforts dedicated to improving education and research in these countries have been provided by international organizations. We describe here the existing educational and research programs that are offered by major international organizations, the barriers and opportunities provided by these collaborations and hope to improve the outcomes of cervical cancer through these efforts.

Can acclimation of thermal tolerance, in adults and across generations, act as a buffer against climate change in tropical marine ectotherms?

Thermal acclimation capacity was investigated in adults of three tropical marine invertebrates, the subtidal barnacle Striatobalanus amaryllis, the intertidal gastropod Volegalea cochlidium and the intertidal barnacle Amphibalanus amphitrite. To test the relative importance of transgenerational acclimation, the developmental acclimation capacity of A. amphitrite was investigated in F1 and F2 generations reared at a subset of the same incubation temperatures. The increase in CTmax (measured through loss of key behavioural metrics) of F0 adults across the incubation temperature range 25.4-33.4°C was low: 0.00°C (V. cochlidium), 0.05°C (S. amaryllis) and 0.06°C (A. amphitrite) per 1°C increase in incubation temperature (the acclimation response ratio; ARR). Although the effect of generation was not significant, across the incubation temperature range of 29.4-33.4°C, the increase in CTmax in the F1 (0.30°C) and F2 (0.15°C) generations of A. amphitrite was greater than in the F0 (0.10°C). These correspond to ARR's of 0.03°C (F0), 0.08°C (F1) and 0.04°C (F2), respectively. The variability in CTmax between individuals in each treatment was maintained across generations, despite the high mortality of progeny. Further research is required to investigate the potential for transgenerational acclimation to provide an extra buffer for tropical marine species facing climate warming.

Dramatic band gap reduction incurred by dopant coordination rearrangement in Co-doped nanocrystals of CeO2.

A dramatic band gap narrowing of 1.61 eV has been observed in Co-doped nanocrystals of CeO2 (ceria), as a result of thermal annealing, without changing the ceria crystal structure and the Co concentration. As demonstrated by x-ray absorption fine structures, thermal annealing incurs an oxygen coordination rearrangement around Co atoms from an octahedral coordination to a square-planar coordination. First principle calculation using density functional theory reveals two stable oxygen coordination types surrounding Co, consistent with the experimental observation. The band gap values calculated for the two stable coordination types differ dramatically, reproducing the experimentally observed band gap narrowing. These prominent effects due to local structure rearrangement around dopant atoms can lead to unprecedented methods for band gap engineering in doped nanocrystal oxides.

Effects of lipid form and source on digestibility of fat and fatty acids in growing pigs.

The objective of this study was to compare the effect of source (corn DDGS, rice bran, or soybean) or form of oil (extracted or intact) on apparent total tract digestibility (ATTD) and true total tract digestibility (TTTD) of acid-hydrolyzed ether extract (AEE) and fatty acids. The study determined and compared the ATTD or TTTD of AEE and fatty acids in extracted corn oil, rice oil, and soybean oil with intact oil in corn DDGS, full-fat rice bran, and full-fat soybean. Seventy-eight barrows (initial BW = 47.2 ± 3.9 kg; Duroc × Landrace × Yorkshire) were allotted to 1 of 13 dietary treatments in a randomized complete block design with 6 barrows in each dietary treatment. The 13 experimental diets included 1 cornstarch-soybean meal basal diet (AEE, 0.56%) and 3 diets containing 6% extracted oils (corn oil, rice oil, and soybean oil) and 9 diets supplemented with 3 levels of corn DDGS (17%, 34%, and 51%), full-fat rice bran (14%, 28%, and 42%), and full-fat soybean (12%, 24%, and 36%). These diets provided about 2%, 4%, and 6% intact oil, respectively. The barrows were housed in individual metabolism crates and were fed the assigned test diets at 4% of initial BW per day. A 5-d total collection of feces followed a 7-d diet adaptation period. The ATTD of AEE were calculated for each diet. The endogenous flow of AEE associated with each ingredient and values for TTTD were calculated using regression methods. The ATTD of AEE were greater ( < 0.05) for extracted oil than for intact oil. Compared to extracted oil, intact oil had lower ( < 0.01) ATTD of palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), and linolenic acid (C18:3). However, a source by form interaction ( < 0.01) was observed for ATTD of C18:0, C18:2, and C18:3. The ATTD of C18:0, C18:2, and C18:3 in extracted corn and rice oil were greater compared with intact corn DDGS and rice oil ( < 0.05), while there was no significant difference for the ATTD of C18:0, C18:2, and C18:3 between extracted soybean oil and intact oil in full-fat soybean. In conclusion, lipids that are extracted have a greater digestibility compared with intact lipids, and this is especially true regarding saturated fatty acids. The ATTD of AEE in 2 forms of rice oil (intact oil and extracted oil) was less than the values in corn oil and soybean oil. The TTTD of AEE in corn DDGS and full-fat soybeans were greater than in full-fat rice bran.

Social Cooperation and Disharmony in Communities Mediated through Common Pool Resource Exploitation.

It was theorized that when a society exploits a shared resource, the system can undergo extreme phase transition from full cooperation in abiding by a social agreement, to full defection from it. This was shown to happen in an integrated society with complex social relationships. However, real-world agents tend to segregate into communities whose interactions contain features of the associated community structure. We found that such social segregation softens the abrupt extreme transition through the emergence of multiple intermediate phases composed of communities of cooperators and defectors. Phase transitions thus now occur through these intermediate phases which avert the instantaneous collapse of social cooperation within a society. While this is beneficial to society, it nonetheless costs society in two ways. First, the return to full cooperation from full defection at the phase transition is no longer immediate. Community linkages have rendered greater societal inertia such that the switch back is now typically stepwise rather than a single change. Second, there is a drastic increase in social disharmony within the society due to the greater tension in the relationship between segregated communities of defectors and cooperators. Intriguingly, these results on multiple phases with its associated phenomenon of social disharmony are found to characterize the level of cooperation within a society of Balinese farmers who exploit water for rice production.

Concentrations of minerals in pig feed ingredients commonly used in China.

Mineral concentrations were determined in 13 different feed ingredients commonly used in swine diets. Ingredients included corn and 4 corn co-products: corn gluten feed, corn gluten meal, corn germ meal, and corn distillers dried grains with solubles (DDGS). Wheat, wheat bran, and wheat shorts were also included, and 5 oilseed meals including soybean meal, rapeseed meal, sunflower meal, cottonseed meal, and peanut meal were used as well. Corn grain contained 88.7% dry matter (DM) and 0.46% K (DM basis). Greater concentrations of DM, ash, Ca, P, nonphytate P, Cu, Fe, Mn, and Zn were observed in corn gluten feed, corn DDGS, and corn germ meal compared with corn grain (P < 0.05). In general, minerals in corn DDGS were approximately three times greater than in corn grain and about 90% of the total P in corn DDGS was in the nonphytate bound form. Corn gluten meal had the least concentrations (P < 0.05) of most minerals, but the greatest (P < 0.05) concentrations of Fe (373.55 mg/kg, DM basis), Cu (11.88 mg/kg, DM basis), and Se (0.92 mg/kg, DM basis). On a DM-basis, concentrations of DM, Ca, P, phytate bound P, and Fe in wheat grain were 88.2%, 0.10%, 0.34%, 0.16%, and 53.48 mg/kg, respectively. Wheat bran contained more (P < 0.05) K, Mg, Cl, Fe, Zn, and Mn compared with wheat and wheat shorts. On a DM-basis, 2.72% K was observed in soybean meal, which was more (P < 0.05) than in the other oilseed meals. However, rapeseed meal had the greatest (P < 0.05) concentration of ash (9.37%), Ca (1.01%), P (1.05%), and Fe (526.49 mg/kg) among the oilseed meals, but only 16.2% of the total P in rapeseed meal was non-phytate P. In contrast, more than 50% of the P in soybean meal and peanut meal was non-phytate P. The least (P < 0.05) concentration of Cu (6.73 mg/kg, DM basis) was observed in rapeseed meal and the greatest (P < 0.05) concentration (32.75 mg/kg) was analyzed in sunflower meal. Concentrations of most minerals in soybean meal, rapeseed meal, sunflower meal, cottonseed meal, and peanut meal varied considerably compared with published values. In conclusion, the concentration of minerals in 13 commonly used feed ingredients were analyzed and results indicated considerable variation among and within feed ingredients for most minerals, which for some minerals may be a result of differences in minerals in the soil in which the ingredients were grown, but processing likely also contributes to differences among ingredients.

The Epidemiology and Characteristics of Q fever and Co-infections with Scrub Typhus, Murine Typhus or Leptospirosis in Taiwan: A Nationwide Database Study.

Q fever (QF) is a worldwide zoonosis associated with outbreaks. Only a few nationwide studies regarding the surveillance and epidemiology of human QF have been reported. Although QF is endemic in Taiwan, a nationwide database investigation of the epidemiology and characteristics of QF and its associations with scrub typhus (ST), murine typhus (MT) and leptospirosis (LS) has never been reported. We analysed nationwide databases of suspected QF, ST, MT and LS cases from October 2007 to December 2014 obtained from the Centers for Disease Control, Taiwan. A total of 468 (4.2%) QF cases were identified among 11 109 suspected QF cases. QF cases were mainly distributed in the southern and Kaohsiung-Pingtung regions but rarely in the eastern region. Compared to non-QF cases, QF cases had significantly higher percentages of males (88.7 versus 66.2%) and high-risk occupations (farming, animal husbandry or veterinary medicine) (16.2 versus 10.5%). But the percentages of specific animal contact, including cattle (0.6 versus 0.8%) and goats (0.9 versus 1.0%), were low in both. The majority of suspected QF cases (89.4%) were simultaneously suspected with ST, MT or LS, and the combinations of suspected diseases differed between regions. The number of suspected QF cases from the eastern region decreased since 2009, which was not observed in other regions. A total of 1420 (12.8%) cases had confirmed diseases, including QF (453, 4.1%), QF+ST (7, 0.06%), QF+MT (4, 0.04%), QF+LS (4, 0.04%), MT (186, 1.7%), ST (545, 4.9%), ST+LS (11, 0.1%) and LS (210, 1.9%). Compared to cases of unknown disease, QF cases had larger percentages of high-risk occupations (16.2 versus 9.6%) but similar histories of animal contact (29.8 versus 25.1%). QF is an endemic disease in southern Taiwan. It is difficult to differentiate QF from ST, MT or LS only by high-risk occupations and history of animal contact, and co-infection of QF with these diseases should be considered.

Single-domain multiferroic BiFeO3 films.

The strong coupling between antiferromagnetism and ferroelectricity at room temperature found in BiFeO3 generates high expectations for the design and development of technological devices with novel functionalities. However, the multi-domain nature of the material tends to nullify the properties of interest and complicates the thorough understanding of the mechanisms that are responsible for those properties. Here we report the realization of a BiFeO3 material in thin film form with single-domain behaviour in both its magnetism and ferroelectricity: the entire film shows its antiferromagnetic axis aligned along the crystallographic b axis and its ferroelectric polarization along the c axis. With this we are able to reveal that the canted ferromagnetic moment due to the Dzyaloshinskii-Moriya interaction is parallel to the a axis. Furthermore, by fabricating a Co/BiFeO3 heterostructure, we demonstrate that the ferromagnetic moment of the Co film does couple directly to the canted moment of BiFeO3.

The Nutritive Values in Different Varieties of Corn Planted in One Location Fed to Growing Pigs over Three Consecutive Years.

This experiment was conducted to determine the effect of variety and planting year on the nutritive values of corn fed to growing pigs. Four corn varieties examined in this experiment were planted in the same village located in Longhua County, Heibei Province, China, in 2012, 2013, and 2014, respectively. During each year, corn was hand-harvested in early October and sun dried to about 14% moisture content. Three batches of twenty-four barrows (33.27±4.30, 31.88±2.93, 34.21±3.81 kg body wight [BW] in 2012, 2013, and 2014, respectively) were used and allotted to a complete block design with 4 diets and 6 replicate pigs per diet. Pigs were individually placed in metabolic crates. The four experimental diets were formulated by mixing each variety of corn and vitamins and minerals, respectively. A five-day collection period followed a seven-day diet acclimation period. The results indicated that variety of corn significantly influenced the available energy content (digestible energy [DE] on dry matter basis, p<0.05; metabolizable energy (ME) on dry matter basis, p<0.05, respectively), and the apparent total tract digestibility (ATTD) of organic matter (p<0.01), dry matter (p<0.05), gross energy (p<0.05), neutral detergent fiber (p<0.01), acid detergent fiber and ether extract (p<0.05). The planting year also significantly influenced the available energy contents (DE on dry matter basis, p<0.05; ME on dry matter basis, p<0.01, respectively) and the ATTD of neutral detergent fiber (p<0.01), acid detergent fiber (p<0.01), crude protein (p<0.01), and ether extract (p<0.01). No interaction was observed between the variety and planting year in DE and ME contents in corn. In conclusion, the variety and planting year significantly influenced the available energy and nutrient digestibility of corn fed to growing pigs.
