Authors: Sun Yuanfeng , Chang Jinfeng , Fang Jingyun 
Published: October 2022

AbstractNet primary productivity (NPP) over global grasslands is crucial for understanding the terrestrial carbon cycling and for the assessments of wild herbivores food security. During the past few decades, numerous field investigations have been conducted to estimate grassland NPP since the measuring criterion released by the International Biological Program. However, a comprehensive NPP database, particularly for belowground NPP (BNPP), in global grasslands is rare to date. Here, field NPP measurements from 438 publications (1957–2018) in global grasslands were collected, critically filtered, and incorporated in a comprehensive global database with observations for aboveground NPP (ANPP), BNPP, total NPP (TNPP), and BNPP fraction (fBNPP). Associated information on geographical locations, climatic records, grassland types, land use patterns, manipulations subjected to manipulative experiments, sampling year of study sites, as well as NPP measurement methods are also documented. This database included 2985 entries from 1785 study sites. Among them, 806 entries contained paired data of ANPP and BNPP, resulting in the 806 fBNPP data. The study sites encompassed global grasslands with latitudinal range of 54.5° S~78.9° N, longitudinal range of 157.4° W~175.8° E, and altitudes from 0 to 5168 m above sea level, covering broad climatic gradients (−17.6 to 28.8°C in mean annual temperature and 63–2052 mm in mean annual precipitation). This global database is the world's largest paired data of ANPP and BNPP field measurements in grasslands. It can be used to study the spatio‐temporal patterns of NPP and its allocation, evaluate the responses of above‐ and below‐ground carbon components to future global changes, and validate the NPP estimation by empirical or process‐based models in global grasslands. The database can be freely used for noncommercial applications. We kindly request users cite this data paper when using the database, respecting all the hard work during data compilation.

Published: October 2022

AbstractMulti‐modal services will become the mainstream in future applications, including video, audio, and haptic flows. In multi‐modal services, video and audio primarily require high‐rate transmission, while haptic flow requires ultra‐high reliability and ultra‐low latency transmission, which imposes unprecedented challenges on the network. To improve the transmission efficiency of multi‐modal services, this article proposes a cross‐modal communication architecture in the cloud radio access network based on network slicing technology. First, we take the data rate and transmission latency of video, audio, and haptic flows contents as the quality of service (QoS) parameters, and send different modes of flows into varying slices for transmission. Second, to transmit the cross‐modal services efficiently while saving communication resources as many as possible, we define our optimization goal as the form of return on investment (ROI), that is, we aim to maximize the return of QoS parameters under the limited investment in communication resources. Third, we propose a two‐stage framework to solve this ROI maximization problem. In the first stage, we propose the power control gradient assisted binary search algorithm to solve the power control problem, which can achieve the optimization of data rate and transmission latency and obtain the suitable QoS. Then, in the second stage, we introduce the network slicing ant colony optimization algorithm to solve the slice resource allocation problem, and get the largest possible ROI. The simulation results verify the effectiveness of the proposed cross‐modal communication architecture, and prove the optimum of the proposed algorithm in terms of ROI compared to some existing algorithms, such as the reverse labeling Dijkstra algorithm, the delay acceptance algorithm, and the random searching algorithm.

AbstractThe assessment of resting perfusion measures (mean transit time, cerebral blood flow, and cerebral blood volume) with magnetic resonance imaging currently requires the presence of a susceptibility contrast agent such as gadolinium. Here, we present an initial comparison between perfusion measures obtained using hypoxia‐induced deoxyhemoglobin and gadolinium in healthy study participants. We hypothesize that resting cerebral perfusion measures obtained using precise changes of deoxyhemoglobin concentration will generate images comparable to those obtained using a clinical standard, gadolinium. Eight healthy study participants were recruited (6F; age 23–60). The study was performed using a 3‐Tesla scanner with an eight‐channel head coil. The experimental protocol consisted of a high‐resolution T1‐weighted scan followed by two BOLD sequence scans in which each participant underwent a controlled bolus of transient pulmonary hypoxia, and subsequently received an intravenous bolus of gadolinium. The resting perfusion measures calculated using hypoxia‐induced deoxyhemoglobin and gadolinium yielded maps that looked spatially comparable. There was no statistical difference between methods in the average voxel‐wise measures of mean transit time, relative cerebral blood flow and relative cerebral blood volume, in the gray matter or white matter within each participant. We conclude that perfusion measures generated with hypoxia‐induced deoxyhemoglobin are spatially and quantitatively comparable to those generated from a gadolinium injection in the same healthy participant.

AbstractHemophagocytic lymphohistiocytosis (HLH) is a heterogeneous group of hyperinflammatory statuses that are difficult to diagnose and can be life‐threatening. Bone marrow (BM) hemophagocytosis is one of the diagnostic criteria according to HLH 2004 diagnostic criteria and HS score. Limited studies have focused on the prognostic factors of BM hemophagocytosis and its association with hematologic malignancies. We aimed to analyze the clinical significance of BM hemophagocytosis. Patients with BM hemophagocytosis, either by cytology or pathology, were enrolled at Taipei Veterans General Hospital from January 2002 to July 2021. Relevant clinical and laboratory data were extracted from medical records. Of 119 patients with BM hemophagocytosis, 57 were diagnosed with hematologic malignancies. The median age of the patients was 58, ranging from 21 to 90. Splenomegaly (adjusted odds ratio [aOR] 2.96; 95% confidence interval [CI] 1.13–7.79) was a risk factor for hematologic malignancies, while autoimmune disease (aOR 0.07; 95% CI 0.01–0.39) and increased D‐dimer (aOR 0.25; 95% CI 0.07–0.92) were protective factors. Risk factors for mortality in patients with BM hemophagocytosis were hematologic malignancies (adjusted hazard ratio [aHR] 2.34; 95% CI 1.24–4.44), Eastern Cooperative Oncology Group score ≥3 (aHR 2.42; 95% CI 1.20–4.89) and thrombocytopenia (aHR 3.09; 95% CI 1.04–9.16). In conclusion, among patients with BM hemophagocytosis, splenomegaly was a predictor of hematologic malignancies. Patients with hematologic malignancies, poor performance status, or thrombocytopenia had a higher mortality risk. Further validation studies are warranted.

AbstractBackground and AimThe coronavirus‐19 is an ongoing global pandemic resulting in millions of deaths worldwide. For a patient population at higher risk of infection, telemedicine is a promising means of providing safe and alternative care routes while minimizing their risk of exposure. This study gives insight into patients' experiences and satisfaction with telemedicine during this pandemic.MethodsWe conducted a cross‐sectional study on 297 patients (RR: 85%) at the National Center for Cancer Care and Research (NCCCR), Qatar. Data was collected through electronic medical records of the eligibe patient population, and phone calls were made whereby the physician read a standard introductory script followed by a survey questionnaire. We focused on patients' experience with telemedicine services amid the pandemic. This was done using a six‐point Likert scoring system of seven questions that were scaled from 1 to 6.ResultsMore than 80% of patients somewhat to strongly agreed that telemedicine met their healthcare needs, improved their confidence in their healthcare system, and were generally satisfied with the quality of care provided. Nearly all patients (90%) understood their physicians' recommendations over the phone. In addition, more than half of the patients (89%) felt they could freely communicate their concerns. Patients also showed an inclination towards face‐to‐face consultations at 68%; however, 90% were willing to participate in future teleconsultations.ConclusionOur study indicates an overall positive experience among patients towards the use of telemedicine. Telemedicine is a safe, futuristic approach toward patient care management and, thus, provides healthcare professionals a platform to implement further patient and physician education. Even though our data also showed that patients liked in‐person visits to some degree, this needs to be looked into more in future studies.

AbstractBackground and AimsPatient satisfaction is an important quality indicator of health care service. The concept of home‐based palliative care has been recently introduced in Bangladesh, but the patients' satisfaction with this care remained unexplored. This study aimed to assess the satisfaction of the cancer patients receiving this care.MethodsThis cross‐sectional study was conducted among 51 surviving cancer patients above 18 years of age registered under the home‐based care service of the Department of Palliative Medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. Data were collected by face‐to‐face interviews using a structured questionnaire based on the FAMCARE P16 questionnaire from February to March 2019. Descriptive analysis was done for the sociodemographic and satisfaction‐related indicators. A correlation matrix was done to see the correlation among the satisfaction indicators.ResultThe majority of the patients (88.2%) were satisfied with the service provided by the home care team. Most (76.5%) of the patients were women, and the mean age was 56.25 ± 14.8 years. The median duration of getting home‐based care was 4 months. Main satisfaction indicators were—assessment of physical symptoms (70.6%), providing information about pain management (70.6%), the inclusion of the family in decision making (76.5%), coordination of care between the members of the home care team (84.3%) and availability of doctors, nurses and palliative care assistants (74.5%). A high correlation was observed between satisfaction regarding the care of physical symptoms and provision of information (R = 0.814, p < 0.001). Also, satisfaction regarding the provision of information and support provided to the family is highly correlated (R = 0.722, p < 0.001).ConclusionDespite the limitations, the overall satisfaction level of the patients regarding home‐based palliative care services in Bangladesh is very high. Home‐based palliative can be a solution to provide palliative care to patients who are unable to access institution‐based care and improve their quality of life.

AbstractBackground and AimsPostoperative cardiac outcomes after intracardiac repair (ICR) are determined by numerous factors whereas right ventricle (RV) dysfunction is considered essential for them, as only few studies attempted to evaluate it postsurgically. RV's function is supposed to be the strong prognostic factor for patients diagnosed with congenital heart defects; therefore, assessing it is the main objective of the study.MethodsThis is a prospective single‐centered cohort study performed on 50 pediatric patients with congenital heart disease (CHD) who underwent ICR between January 2019 and January 2022. All patients underwent echocardiographic assessment of RV function via tricuspid annular plane systolic excursion (TAPSE) and fractional area change (FAC) at 1, 24, and 48 h. After surgery, where pre‐ and postoperative RV pressure, cardiopulmonary bypass (CPB), and aortic cross‐clamp (ACC) time were assessed. Similarly ventilation intensive care unit (ICU) and hospital stay times and mediastinal drainage were also monitored.ResultsThe mean ± standard deviation for pre‐ and postoperative RV pressure was 49.1 ± 16.12 and 42.7 ± 2.9 mmHg, respectively, whereas that for pre‐ and postoperative pulmonary artery pressure was 30.4 ± 2.6 and 24.2 ± 12.9 mmHg, with p value of <0.002 and <0.001, respectively. The mean ± standard deviation of CPB and ACC times was 120.92 ± 74.17 and 78.44 ± 50.5 min accordingly, while those for mean ± standard deviation of ventilation time, mediastinum chest drainage, ICU and hospital stays were 30.36 ± 54.04, 43.78 ± 46.7 min, 5.9 ± 4.01 h, were 30.36 ± 54.0, 43.78 ± 46.7 min, 5.9 ± 4.01 and 10.3 ± 4.83 h, respectively.ConclusionsRV dysfunction plays the important role in longer recovery and intraoperative time, while its effect is mostly transient. The use of TAPSE and FAC methods is valuable in the evaluation of postoperative outcomes, and the former proved to be more effective.

IntroductionTesticular ectopia refers to abnormal positioning of testis, which includes a wide variety of variants. An ectopic testis is located off the normal path of male gonadal descent, unlike conventional undescended testis.Case presentationA 37‐year‐old man presented with the complaint of a palpable lesion in the scrotum. Magnetic resonance imaging of the scrotum revealed bilateral testes on the respective opposite sides of the scrotum with bilateral spermatic cords crossing under the base of the penis. Accordingly, he was diagnosed as “left‐right reversal of the testes within the scrotum.” In retrospect, the “palpable” lesion was thought to be the spermatic cords crossing above the testes. Semen analysis identified deteriorated sperm motility, suggesting possible male infertility.ConclusionThis case of left–right reversal of the testes within the scrotum is probably a new variant of testicular ectopia that has never been reported.

Published: October 2022

AbstractPhosphoglycerate dehydrogenase (PHGDH) deficiency is a rare autosomal recessive genetic disease of serine biosynthesis. Its typical features are congenital microcephaly, epileptic seizures, and psychomotor developmental delay. Here, we reported the first Chinese familial cases with genetically confirmed PHGDH deficiency and reviewed several previous reports. Two siblings in this family presented with microcephaly, psychomotor retardation, and epilepsy in early juvenile. Brain magnetic resonance imaging (MRI) showed only a slight change of enlarged ventricle. Biochemical investigations revealed low serum serine and glycine concentrations. The whole‐exome sequencing (WES) results identified a missense variant in the PHGDH gene (NM_006623.4: exon11: c.1211T>A, p. Val404Asp). Although two patients in this Chinese family carried the same pathogenic mutation in the PHGDH, their symptoms and responses to treatment were not exactly the same. We found a novel variant in the PHGDH gene and expanded the genotypic and phenotypic spectrum of serine biosynthesis disorders.

AbstractExtreme temperature events (ETEs) have evolved alongside the warming climate over most parts of the world. This study provides a statistical quantification of how human influences have changed the frequencies of extreme temperatures in New Zealand, depending on the synoptic weather types. We use the ensembles under pre‐industrial conditions (natural scenarios with no human‐induced changes) and present‐day conditions (anthropogenic scenarios) from the weather@home regional climate model. The ensemble simulations under these two scenarios are used to identify how human influences have impacted the frequency and intensity of extreme temperatures based on their connection to different large‐scale circulation patterns derived using self‐organizing maps (SOMs). Over New Zealand, an average two to three fold rise in frequencies of extremes occurs irrespective of seasons due to anthropogenic influence with a mean temperature increase close to 1°C. For some synoptic situations, the frequency of extremes are especially enhanced; in particular, for low‐pressure centres to the northeast of New Zealand where the frequency of occurrence of daily temperature extremes has increased by a factor of 7 between anthropogenic and natural ensembles for the winter season, though these synoptic patterns rarely occur. For low‐pressure centres to the northwest of New Zealand, we observe high temperatures frequently in both anthropogenic and natural ensembles which we expect is probably associated with warm air advection from the Tropics. The frequency of occurrence of high temperatures in these synoptic patterns has also increased by a factor of 2 between the natural and anthropogenic ensembles. For these synoptic states, the extremes are observed in the North Island and along the east coast of the country with the highest temperature along the Canterbury coast and Northland. The change between the natural and anthropogenic ensembles is largest on the west coast along the Southern Alps for all the synoptic circulation types.

Published: October 2022

ABSTRACTGlacial periods and their terminations are useful for assessing the full scale of natural climate variability in the diverse climate regions of West Asia (i.e. deserts, mountains, alluvial plains, coastal zones). In this study, we report the first stalagmite stable isotope (δ18O and δ13C) records from the southern Zagros Mountains in southwest Iran. The records partially span the period from the Last Glacial Maximum (LGM) to the early Holocene, 24.2–9.6 thousand years before the present. The southwest Iran stalagmite δ18O and δ13C records indicate that climate and environment in the area differed substantially between the LGM and early Holocene. High stalagmite δ13C values are found at the LGM (7‰ greater compared to the early Holocene), and are attributed to sparse vegetation and reduced soil bio‐productivity, and possibly a greater degree of prior calcite precipitation in the epikarst, as a result of a cold and dry climate. Stalagmite δ18O values are also high at the LGM (4‰ greater compared to the early Holocene), and are attributed to lower temperatures (larger water–calcite isotope fractionation) and higher δ18O values of the moisture sources (Mediterranean and Red Seas). Through the deglaciation, stalagmite δ18O, δ13C and/or growth features coincide with the North Atlantic Heinrich Stadial 1, the Bølling–Allerød warm period and the Younger Dryas cold event, supporting a relationship between southern Zagros climate and the North Atlantic millennial events.
