Published: March 2022

Objective Mothers of preterm infants face unique challenges in establishing milk supply. We hypothesized that daily meditation practice while pumping would increase milk volume.
Study Design This was a randomized control trial examining the effect of meditation on the breastmilk supply of women delivering preterm infants. The meditation group engaged in daily use of a mindfulness-focused meditation app in addition to routine lactation support. The primary outcome was mean breastmilk volume on the infant's nineth day of life. Secondary outcomes included use of lactation-promoting behaviors, continuation of breastfeeding, and measures of mental health and breastfeeding self-efficacy by validated questionnaires. In addition to the intention to treat analysis, a per protocol analysis examined the association of frequent meditation with these breastfeeding and mental health outcomes.
Results A total of 60 women were analyzed. Mean milk volume was 647.1 ± 467.8 mL in the meditation group and 514.9 ± 393.5 mL in the routine care group (p = 0.27). Median number of pumping sessions was 7 (interquartile range [IQR] 5–8) in the meditation group, compared to 6 (IQR 4–7) in the routine care group (p = 0.11). Other lactation-promoting behaviors, breastfeeding continuation, and questionnaire scores were similar.Adjusting for confounders, we found an increase in breastmilk production of 223.2 mL (95% CI 98.8–347.5, p = 0.001) and in pumping episodes by 0.93 (95% CI 0.16–1.70, p = 0.020) associated with frequent meditation. Skin-to-skin contact was increased to 100% (p = 0.006) among women who meditated seven or more times. Adjusted odds of a clinically significant Edinburgh Postnatal Depression Scale score of >9 was 0.057 (95% CI 0.0014–0.711, p = 0.023) with frequent meditation.
Conclusion Breastmilk production was similar in mothers practicing meditation compared to those receiving routine lactation support. For women engaging in frequent mediation, there may be an effect in establishing breastmilk supply and reduction of depression symptoms.

Published: March 2022

Abstract
Introduction Meningiomas are common tumors of the central nervous system that represent around 30% of primary tumors. However, the incidence of atypical meningiomas (AMs) is lower, of approximately 15% of all meningiomas, and they present high rates of relapse and mortality.
Aim To review peculiarities of AMs.
Methodology A literature review of articles published in English between 2009 and 2020 on the PubMed and Biblioteca Virtual em Saúde (BVS) databases using the terms meningioma and atypical.
Results Atypical meningiomas are rare and more prevalent in older males. The clinical condition depends on the site of the tumor, and a definitive diagnosis of AM is only possible via anatomical pathology. Moreover, prominent studies have indicated a relationship between the presence of the anti-Ki67 antibody/mindbomb (Ki-67/MIB1) marker as an aid in the definition of AM and one of the determinants of tumor aggressiveness. Imaging studies have also advanced in terms of seeking criteria using magnetic resonance that may suggest the malignancy of a lesion. As far as treatment is concerned, total resection remains the main therapeutic option, and it has a direct relationship with survival and time until disease progression. Lastly, there are many factors involved in the prognosis of AM.
Conclusion Atypical meningiomas continue to be a challenge, requiring further and more specific studies to provide a better understanding of it.

AbstractRotavirus infection has been reported to be associated with neonatal seizures with a diffuse and symmetrical diffusion restriction of periventricular white matter, namely, neonatal rotavirus-associated leukoencephalopathy. The extensive white matter injury seen in this cohort raises concerns about the long-term neurodevelopmental outcomes. In the present study, we prospectively assessed the neurodevelopmental outcomes of 13 patients with neonatal rotavirus-associated leukoencephalopathy at a median age of 26 months (range, 23–68 months). Neurodevelopmental outcomes were evaluated using a neurological examination, developmental evaluations, and magnetic resonance imaging (MRI) of the brain. Overall, 6 of the 13 patients (46%) had abnormal neurodevelopmental outcomes: 1 patient had mental retardation, visual–motor integration (VMI) dysfunction, cerebral palsy, and epilepsy; 1 patient had cerebral palsy and VMI dysfunction; remaining 4 patients had VMI dysfunction. Follow-up MRI in 12 of 13 patients showed an increased signal intensity on periventricular white matter in all patients. These findings suggested that neonatal rotavirus-associated leukoencephalopathy could not be assumed to be benign in long-term neurodevelopment, particularly in VMI function. Early intervention and long-term follow-up are necessary for these patients. Our findings raise caution for rotavirus infection in this vulnerable population for infants.

Published: March 2022

Abstract
Background One key aspect of a learning health system (LHS) is utilizing data generated during care delivery to inform clinical care. However, institutional guidelines that utilize observational data are rare and require months to create, making current processes impractical for more urgent scenarios such as those posed by the COVID-19 pandemic. There exists a need to rapidly analyze institutional data to drive guideline creation where evidence from randomized control trials are unavailable.
Objectives This article provides a background on the current state of observational data generation in institutional guideline creation and details our institution's experience in creating a novel workflow to (1) demonstrate the value of such a workflow, (2) demonstrate a real-world example, and (3) discuss difficulties encountered and future directions.
Methods Utilizing a multidisciplinary team of database specialists, clinicians, and informaticists, we created a workflow for identifying and translating a clinical need into a queryable format in our clinical data warehouse, creating data summaries and feeding this information back into clinical guideline creation.
Results Clinical questions posed by the hospital medicine division were answered in a rapid time frame and informed creation of institutional guidelines for the care of patients with COVID-19. The cost of setting up a workflow, answering the questions, and producing data summaries required around 300 hours of effort and $300,000 USD.
Conclusion A key component of an LHS is the ability to learn from data generated during care delivery. There are rare examples in the literature and we demonstrate one such example along with proposed thoughts of ideal multidisciplinary team formation and deployment.

The purpose of this document was to summarize the panel’s discussions on habilitative principles, state- of-the-art practices, and future needs for infants with hearing loss.
Research on a large opening and high flow rate piezoelectric pump with straight arm wheeled check valve
Authors: He Lipeng , Hou Yi , Hu Dianbin , Hu Renhui , Zhang Zheng , Cheng Guangming 
Published: March 2022

Piezoelectric pumps are applied in cooling systems of microelectronic devices because of their small size. However, cooling efficiency is limited by the low flow rate. A straight arm wheeled check valve made of silica gel was proposed, which can improve the flow rate of piezoelectric pumps, solve the influence of glue aging on the sealing ability of a wheeled check valve, and reduce the size of piezoelectric pumps. This paper discusses the influence of the valve arm number (N = 2, 3, and 4), the valve arm width (W = 1.0, 1.2, and 1.4 mm), and the valve thickness (T = 0.6, 0.8, and 1.0 mm) on the flow rate characteristics of piezoelectric pumps. When valve opening rises, the flow rate increases. The simulation results show that valves with 2 valve arm number, 0.6 mm valve thickness, and 1.0 mm valve arm width have maximum valve opening. The experimental results show that piezoelectric pumps with different valve parameters have different optimal frequencies. In addition, the maximum flow rate is 431.6 ml/min at 220 V and 70 Hz. This paper provides a reference for the application of piezoelectric pumps in cooling systems.
Poor welfare outcomes resulting from poor management decisions in a translocation of western grey kangaroos (Macropus fuliginosus)
Authors: Thompson Graham G. , Thompson Scott A. , Pusey Anthony 
Published: March 2022

There is often considerable social media commentary on whether remnant kangaroo populations in urban areas should be euthanased or translocated. Here, we describe a translocation program in Western Australia where kangaroos were herded into a temporary enclosure, darted, sedated, and translocated to a site in the State Forest east of the Swan Coastal Plain where they were released after 24 h. Prior to darting and after being initially herded into a temporary holding enclosure, kangaroos were repeatedly released from the enclosure by members of the public. Sixty-three of 154 adult kangaroos and 20 of 52 pouched young (40.3%) died or were euthanased before being released from the translocation release enclosure. The total volume of the sedative Zoletil (mL kg−1) injected into kangaroos as a sedative was significantly higher in those that survived than those that died. The primary conclusion from this management program was that the western grey kangaroos were susceptible to capture myopathy and distressed animals are at a greater risk of not surviving a translocation program. In our professional judgement, from an animal welfare perspective, these kangaroos should have been euthanased and not translocated. Such scientific advice and professional experience should inform future decisions regarding management of remnant kangaroo populations.

Significance
While most small, regulatory RNAs are thought to be “noncoding,” a few have been found to also encode a small protein. Here we describe a 164-nucleotide RNA that encodes a 28-amino acid, amphipathic protein, which interacts with aerobic glycerol-3-phosphate dehydrogenase and increases dehydrogenase activity but also base pairs with two mRNAs to reduce expression. The coding and base-pairing sequences overlap, and the two regulatory functions compete.
Autopsy Results from a COVID-19 Patient Treated in a Tropical Area, and a Review of the Epidemiological History

Published: March 2022

Abstract
Since the start of the COVID-19 pandemic, there has been an urgent need to produce accurate and sensitive tests. However, there have been instances where a positive nucleic acid test turns negative after treatment, and then positive again. This case report describes such an instance from the tropical region of Hainan, China. The patient was a 61-year-old female who went to Hainan on vacation from Wuhan during the COVID-19 pandemic in 2020. Symptoms appeared 9 d after arriving in Hainan, and it was confirmed that the nucleic acid test was positive after 4 repeats. Her condition declined rapidly, her heart stopped beating, and she was admitted in a coma to the ICU. After treatment, the SARS-CoV-2 virus nucleic acid test of several nasopharyngeal swabs were negative, and tests on whole blood, anal swabs, and urine were also negative. Later, however, nucleic acid tests on a lower respiratory tract sputum swab and lower respiratory tract lavage fluid were positive. An autopsy examination was carried out 12 h after her death, and multi-organ secretions were extracted for nucleic acid testing. The SARS-CoV-2 virus nucleic acid was only detected in the swabs from the end of the bronchus, which was confirmed by the visualization of the coronavirus by electron microscopy. Autopsy confirmed that the damage was mainly concentrated in the lungs and immune organs and tissues throughout the body. Epidemiology indicated that none of the people she came into contact with after arriving in Hainan, including close contacts, were infected. This is in sharp contrast to the highly contagious virus in Wuhan in the temperate zone during the same period. This case report indicates: (1) The high temperatures in tropical areas may have an impact on the spread and harm of COVID-19, and (2) The reason why nucleic acid testing for COVID-19 was initially negative and then positive after treatment may be related to the survival of the SARS-CoV-2 virus in deep lung tissues.
Direct calibration method of effective wavelength for fiber-optic multi-wavelength pyrometer based on optimization function
Authors: Liang Mei , Wang Yongsheng , Wang Changhui , Wang Yantao 
Published: March 2022

Abstract
The calibration of the temperature and effective wavelength must be carried out before multi-wavelength pyrometers application. The current calibration method of the effective wavelength for the multi-wavelength pyrometers is the pyrometer wavelength function (PWF) method. However, for the actual calibration of the fiber-optic multi-wavelength pyrometer, the signal is too weak to obtain effective wavelength by the PWF. Therefore, a new calibration method based on optimization function for effective wavelength is proposed in this paper. The core idea of the innovation is to transform the effective wavelength calibration into an optimization problem, in which the effective wavelength can be solved directly by the MATLAB software using the temperature calibration data. Comparing with the PWF, the presented new method not only provides a novel way to obtain effective wavelength, but also avoids time-consuming due to the complicated process from the wavelength calibration. Finally, simulation and experimental results verify that the proposed method is effectiveness by using the function fmincon and minconPS from MATLAB software, in which the fmincon function is superior to the minconPS function for the efficiency and anti-noise performance.
Adaptive surge detection of magnetic suspension centrifugal blower based on rotor radial displacement signal and SOGI-FLL with prefilter

Published: March 2022

Abstract
For the surge detection problem of high-speed magnetic suspension centrifugal blower, a second order generalized integral-frequency locked loop with prefilter (SOGI-FLL-WPF) is used for surge detection. This method is utilized to normalize the amplitude and frequency of the surge signal by using the rotor radial displacement signal in the magnetic suspension blower. So that the response speed of detecting surge signal is not affected by the frequency and amplitude, and the frequency of the blower surge vibration signal is tracked adaptively. As a result, the fast response ability of the surge signal detection is improved. Specifically, firstly, the rotor radial displacement signal is collected in real time. And then, the rotor speed is identified by SOGI-FLL, and the identified speed information is input to SOGI for notch. Finally, the surge detection is carried out by SOGI-FLL-WPF for the signal after notch. The 105 kW magnetic suspension centrifugal blower is applied for the surge detection experiment. The experimental results show that the surge detection method based on rotor radial displacement signal and SOGI-FLL-WPF can detect the surge signal immediately after its occurrence. The proposed detection method needs no additional detection unit, and has the advantages of simple algorithm, fast response speed and small amount of calculation. In addition, it can effectively reflect the change of frequency in the process of surge.

Published: March 2022

Abstract
This paper describes an on-chip configurable Digital to Analog Converter (DAC) module for monolithic active pixel sensor. The DAC module consists of four 10-bit voltage DACs, seven 8-bit current DACs, a bandgap circuit, and a configure interface. The voltage DAC is implemented with an R-2R resistor ladder network, and each LSB corresponds to 3 mV. The current DAC is in the current-steering type with a thermometer code. Each LSB of the current DAC corresponds to 10 nA. The bandgap circuit provides a stable, temperature-independent reference voltage of 1.25 V to the DACs. All the DACs can be accessed and configured with the configure interface. The DAC module covers 3074 µm × 400 µm, and the total power consumption is 46.2 mW. This paper will discuss the design and performance of this DAC module.

Published: March 2022

Abstract
This ERL focus collection has published 17 papers that have advanced our understanding of different dimensions of warming-induced tree mortality. Here we summarize these focus collection papers, organized by four topics related to tree mortality: pathogens, droughts/heat waves, fire/bark beetles, and teleconnections/air pollution. This focus collection illustrates a variety of methods in measuring and modeling tree-mortality, and adds significant new research findings into the scientific literature on tree mortality from hotter droughts. Some of these results also are useful for policymakers and forest managers in addressing amplified forest stress and tree mortality as a result of increasingly severe warming-induced climate and weather extremes.

Abstract
Many solar photovoltaic (PV) energy projects are currently being planned and/or developed in West Africa to sustainably bridge the increasing gap between electricity demand and supply. However, climate change will likely affect solar power generation and the atmospheric factors that control it. For the first time, the state-of-the-art CMIP climate models (CMIP6) are used to investigate the potential future evolution of solar power generation and its main atmospheric drivers in West Africa. A multi-model analyses carried out revealed a decrease of solar PV potential throughout West Africa in the 21st century, with an ensemble mean reduction reaching about 12% in southern parts of the region. In addition, the variability of future solar PV production is expected to increase with a higher frequency of lower production periods. The projected changes in the solar PV production and its variability are expected to be predominant in the June to August season. We found the decrease in the solar PV potential to be driven by a decrease of surface irradiance and an increase of near-surface air temperature. However, the decrease of the surface irradiance accounted for a substantially larger percentage of the projected solar PV potential. The decrease in surface irradiance was further linked to changes in both cloud cover and aerosol presence, although generally much more strongly for the former.
