Authors: Wu Chenkai , Yan Lijing L. , Long Qian , Liu Yunguo , Tan Jie , Lou Zhexun , Tang Shenglan 
Published: April 2023

Abstract
Background
There has been considerable progress in developing global health education and research in China. Nevertheless, evidence of the progress of Chinese universities’ contributions to global health research is limited. More efforts are needed to depict the progress Chinese universities have collectively made in advancing the field of global health. This study aimed to examine Chinese universities’ collective contributions to global health research by describing the longitudinal trends in global health research publications, uncovering research themes in global health, and exploring collaboration patterns.

Methods
A comprehensive bibliometric analysis was conducted for original research studies of the ten founding members of the China Consortium of Universities for Global Health, one of the largest networks of global health research and education in China.

Results
We found that (1) the number of research publications in the field of global health has steadily increased from 2014 to 2020, (2) non-communicable disease was the most popular research topic, accounting for over one-third of total publications, followed by maternal and child health and neurological and mental disorders and diseases, (3) less than one-fifth of papers involved primary data collection, with the majority of the study populations from low-income and lower-middle-income countries in Asia and Africa, and (4) a sizable collaboration network has been established with co-authors from over 200 oversea universities or organizations, with about one third from the US.

Conclusions
Despite a variety of challenges and barriers, Chinese universities have been playing an increasingly important role in global health research as assessed by peer-reviewed publications over the last decade. More concerted efforts by multiple stakeholders, including government, private sectors, funding agencies, academic institutions, and researchers, are needed to advance the development of global health research in China.
Key considerations in the analysis of the development of social anthropology in Spain
Authors: Fernández-Álvarez Óscar , González-González Miguel , Ouali-Fernández Sara 
Published: April 2023

AbstractThe objective of this article is to present a brief overview of the long history of anthropology in Spain. Of primary importance is positioning this history both within Spain’s wider social and political contexts, and also against the development of scientific research throughout the country. Methodologically, this study is based on extensive existing literature concerning the history of the discipline, from the start of the twentieth century to contemporary times, which informed the decision to structure this writing in four sections, segmenting the period of history covered. The first section considers the primary or formative development of a regionalist Spanish ethnography at the beginning of the twentieth century. Following this, in the second section, we explore the Francoist era when the twentieth century was well underway; this was a period marked by the strong influence of foreign research on the establishment of teaching methods and practical approaches to anthropology. In the third section, we observe how, as Spain transitioned from a dictatorship to a strong democratic state formed of autonomous regions, a uniquely Spanish anthropology emerged and, as we discuss in the fourth section, the country entered a time of consolidation and institutionalisation throughout the wider field of Spanish scientific endeavour. In this way, we examine Spanish anthropology from the context of intellectual development not dissimilar to that taking place on a global scale. The article concludes with an exploration of the current challenges facing Spanish anthropology.
Solar-PV inverter for the overall stability of power systems with intelligent MPPT control of DC-link capacitor voltage
Authors: Singh Sheetal , Saini Sanju , Gupta S. K. , Kumar Rajeev 
Published: April 2023

AbstractThis paper demonstrates the controlling abilities of a large PV-farm as a Solar-PV inverter for mitigating the chaotic electrical, electromechanical, and torsional oscillations including Subsynchronous resonance in a turbogenerator-based power system. The oscillations include deviations in the machine speed, rotor angle, voltage fluctuations (leading to voltage collapse), and torsional modes. During the night with no solar power generation, the PV-plant switches to PV-STATCOM mode and works as a Solar-PV inverter at its full capacity to attenuate the oscillations. During full sun in the daytime, on any fault detection, the PV-plant responds instantly and stops generating power to work as a Solar-PV inverter. The PV-farm operates in the same mode until the oscillations are fully alleviated. This paper manifests the control of the DC-link capacitor voltage of the Solar-PV inverter with a bacterial foraging optimization-based intelligent maximum power point tracking controller for the optimal control of active and reactive power. Kundur’s multi-machine model aggregated with PV-plant is modeled in the Matlab/Simulink environment to examine the rotor swing deviations with associated shaft segments. The results for different test cases of interest demonstrate the positive outcomes of deploying large PV-farms as a smart PV-STATCOM for controlling power system oscillations.
Exercise-related leg muscle signal changes: assessment using diffusion-weighted MRI
Authors: Kolmer Floriane , Bierry Guillaume , Willaume Thibault 
Published: April 2023

AbstractWe aimed to detect physiologic changes of leg muscle signal on magnetic resonance (MR) diffusion-weighted imaging (DWI) in asymptomatic subjects after repetitive plantar flexion exercises. In this monocentric prospective study, DWI of both legs were performed at rest and after exercise periods (5 min, Ex5: and 10 min, Ex10) in 20 active healthy subjects (mean age 31 years). The exercise consisted in repetitive plantar flexion of the right foot using elastic band, the patient being sited directly on the MR table. Both visual semiquantitative evaluations and quantitative (apparent diffusion coefficient, ADC; fractional anisotropy, FA) were performed in 5 leg compartments. Visually, signal changes involved mainly the fibular and gastrocnemius muscles and were considered intense after Ex5 in 3 subjects, moderate only after Ex5 in 10, and moderate only after Ex10 in 4. No changes were visible in 3 subjects. Quantitative evaluation confirmed significant signal changes in the fibular (ADC: + 17.4%, p < 0.001; FA: -8.3%, p = 0.030) and gastrocnemius (ADC: + 13.7%, p < 0.001; FA: -11.4%, p < 0.001) muscles between rest and post-exercise MR. Plantar flexion exercises induce changes on DWI, especially in fibular and gastrocnemius muscles, which can be visually and quantitatively detectable in asymptomatic active subjects.Trial registrationEudraCT 2008-A00694-51.

Published: April 2023

Abstract
Background
Citrus fruits are economically and nutritionally important but have been severely affected by Huanglongbing disease (HLB), its natural spread is mainly by the Asian Citrus Psyllid,Diaphorina citri Kuwayama (Hemiptera: Liviidae). Chemicals are often used to control this pest, but this is not sustainable. Meanwhile, there are few environmentally friendly bioinsecticides to control D. citri in China.

Results
In this study, an entomofungal pathogen wz-1 was isolated from a D. citri carcass in the field, which resulted in a cumulative mortality rate of 75.27% in adult D. citri 7 days after inoculation of the spore suspension. It was identified as Cladosporium subuliforme based on morphological analysis as well as sequence analysis of several molecular markers (Internal Transcribed Spacers, Translation Elongation Factor 1-α and Actin). Remarkably, the lethality rate of adult D. citri reached 53.13%, 48 h after treatment with the aqueous phase extracts of wz-1. Hydroxyquinoline and phytosphingosine in the extracts were identified as potentially active metabolites using LC–MS.

Conclusions
The entomopathogenicity and bioinsecticidal potential of C. subuliforme were previously unknown. Obtained results showed that both spores and extracts of wz-1 can effectively kill adult D. citri, providing an available fungal resource and a theoretical basis for biocontrol of the HLB insect vector D. citri.
Sevoflurane effects on left atrial performance: a transesophageal echocardiographic study on patients undergoing coronary artery bypass grafting
Authors: Hasseb Ahmad Mahmoud , Esmat Ibrahim Mamdouh , Ashoor Tarek Mohamed 
Published: April 2023

Abstract
Background
Patients presenting for coronary artery bypass grafting often have left ventricular diastolic dysfunction. These patients are in need for a well contracting left atrium (LA) to generate the required cardiac output. Sevoflurane affects the overall cardiac contractility. This study aimed at evaluating sevoflurane effects on left atrial performance and left ventricular diastolic function for patients undergoing coronary artery bypass graft (CABG) using transesophageal echocardiography (TEE).

Results
Out of 40 enrolled patients, analysis was made for 31 patients. Results after exposure to one MAC sevoflurane revealed a decrease of left atrial functional area change (P = 0.001), left atrial active emptying fraction (P = 0.038), and A wave velocity by transmitral pulsed wave Doppler (P = 0.019) while left ventricular diastolic function was unaffected despite a significant decrease in left ventricular ejection fraction (P = 0.008).

Conclusions
Sevoflurane at one MAC affected the left atrial performance without affecting left ventricular diastolic function in patients with grade I and II diastolic dysfunction undergoing CABG.

Principles of mechanical and chemical debridement with implant retention
Authors: Deckey David G. , Christopher Zachary K. , Bingham Joshua S. , Spangehl Mark J. 
Published: April 2023

Abstract
Background
Periprosthetic joint infection (PJI) is one of the most common causes of early revision for total hip and knee arthroplasty. Mechanical and chemical debridement typically referred to as debridement, antibiotics, and implant retention (DAIR) can be a successful technique to eradicate PJI in acute postoperative or acute hematogenous infections. This review will focus specifically on the indications, techniques, and outcomes of DAIR.

Discussion
The success of mechanical and chemical debridement, or a DAIR operation, is reliant on a combination of appropriate patient selection and meticulous technique. There are many technical considerations to take into consideration. One of the most important factors in the success of the DAIR procedure is the adequacy of mechanical debridement. Techniques are surgeon-specific and perhaps contribute to the large variability in the literature on the success of DAIR. Factors that have been shown to be associated with success include the exchange of modular components, performing the procedure within seven days or less of symptom onset, and possibly adjunctive rifampin or fluoroquinolone therapy, though this remains controversial. Factors that have been associated with failure include rheumatoid arthritis, age greater than 80 years, male sex, chronic renal failure, liver cirrhosis, and chronic obstructive pulmonary disease.

Conclusions
DAIR is an effective treatment option for the management of an acute postoperative or hematogenous PJI in the appropriately selected patient with well-fixed implants.

Published: April 2023

Abstract
Background
Uric acid plays a pivotal role in the regulation of mood and behavior. The study aimed to elucidate the role of serum uric acid as a biomarker in patients with schizophrenia, bipolar affective disorder (BAD), and major depressive disorder (MDD) and to examine its relation to symptom domains and severity of illness.

Results
A total of 150 participants with schizophrenia, BAD, and MDD and 50 healthy controls were recruited. Patients were assessed using Structured Clinical Interview for DSM-IV Axis I Diagnosis (SCID-I), Positive and Negative Syndrome Scale (PANSS), the Young Mania Rating Scale (YMRS), and the Hamilton Depression Rating Scale (HAM-D). General Health Questionnaire (GHQ-28) was applied to healthy controls. Then, a blood draw from all participants was performed to measure serum uric acid level. According to this study, there was a statistically significant difference between patients with schizophrenia, BAD, MDD, and healthy controls, with regard to serum uric acid level (P = 0.007). On correlating symptom domains and severity of schizophrenia, bipolar, and MDD with serum uric acid level, there was only a statistically significant negative correlation between YMRS and serum uric acid level (P = 0.022).

Conclusions
Serum uric acid could be a valuable biomarker in patients with schizophrenia, bipolar, and MDD especially in patients with bipolar disorder.
Major determinant factors of pediatric COVID-19 severity; a single center study
Authors: Ali Heba A. 
Published: April 2023

Abstract
Background
According to several recently published studies, pediatric Corona virus infection is mostly mild. However, a severe COVID-19 illness could occur in children, resulting in grave outcomes. Unfortunately, the data regarding the major determinants of disease progression in the pediatric population is still limited. Here, we aimed to identify the most significant risk factors associated with severe COVID-19 infection in children to predict the patients at elevated risk for serious illness.

Results
This single-center, retrospective study enrolled eighty hospitalized children and adolescents under the age of 18 years with coronavirus type 2 infections, who were divided according to the level of clinical severity into severe and non-severe groups. Epidemiological data, clinical features, radiological findings, laboratory test results, and disease outcomes of the studied patients were collected and analyzed to demonstrate their relation to disease severity. Patients with severe illness tend to have more respiratory symptoms (97.8% vs. 79.4%, p = 0.007), cardiac affection (23 (50.0%) vs. 5 (14.7%), p = 0.001, and neurological involvement (13 (28.1%) vs. 1 (2.9%), p = 0.003). Furthermore, abnormal radiological findings and higher radiological scores were significantly more common among patients with severe disease compared to non-severe cases (p = 0.037, 0.013). In multivariable analysis, clinical scoring, abnormal coagulation function, and ICU admission were the most significant parameters for forecasting severe illness.

Conclusions
We identified the most remarkable parameters involved in the progression of severe disease in Egyptian children with COVID-19 infection, which may be implemented in anticipation of susceptible children for earlier prompt management and a better prognosis.

Authors: Eltonbary Heba Tollah Ahmed Ibrahim , Elmashad Nehal Mohamed , Khodair Sameh Ahmed , Abou Khadrah Rania Sobhy 
Published: April 2023

Abstract
Background
Whole-body diffusion-weighted magnetic resonance is being developed as a tool for assessing tumor spread. Patients with known primary tumors require meticulous evaluation to assess metastasis for better staging; we attempted to detect bony metastasis without radiation exposure. Our study's goal was to use whole-body diffusion-weighted imaging with background body signal suppression (WB-DWBIS) to evaluate bony metastasis in confirmed patients who have primary tumors.

Results
Our study included 90 patients with known primary cancer, 10 patients were excluded as they had no bony metastasis, from 80 patients: 36 (45.0%) having one site of metastasis, 36 (45%) having two sites of metastasis, and 8 (10.0%) having three sites of metastasis. 56 (70.0%) of the metastasis sites were bony metastasis, and 76 were mixed both bony and non-bony, including 32(40.0%) lung, 16 (20.0%) liver, and 28 (35%) lymph nodes. Sensitivity of bone scanning in detecting metastasis was as follows: 95.1% sensitivity and 92.0% accuracy, while that of whole-body diffusion-weighted image with background signals suppression was 94.8% sensitivity and 91.7% accuracy, WB-DWBIS inter-observer agreement in the detection of bony metastatic deposits in cancer patients was good (0.7 45, agreement = 93.2%).

Conclusions
Using WB-DWBIS images, bone lesion identification and characterization (site and number) were improved, producing outcomes similar to bone scanning without the use of ionizing radiation.
Computed tomography predictors of gastroesophageal varices in cirrhotic patients: the added value of portosystemic collaterals
Authors: Solaiman Sara Ateya , Habba Mohamed Refaat , El Kammash Tarek Hamed , Serwah Abdel Hamid Ahmed 
Published: April 2023

Abstract
Background
Detection of ‘spontaneous’ portosystemic collateral veins (PSCV) serves as an important tool in diagnosing portal hypertension (PTHN) and predicting prognosis. Multidetector computed tomography (MDCT) imaging is noninvasive and allows accurate assessment of variceal site and size. So, this study was conducted to assess the role of MDCT in predicting, detecting and grading gastroesophageal varices in correlation with endoscopy in cirrhotic patients in relation to other portosystemic collaterals.

Methods
Analytical cross-sectional prospective study was conducted on 100 cirrhotic patients. All patients were subjected to history taking, upper gastrointestinal endoscopic assessment, and triphasic CT or contrast-enhanced CT assessment of abdomen and pelvis.

Results
Patients who had esophageal varices in MDCT show a statistically significant difference (p = 0.016) with its endoscopic grading. There was good agreement between endoscopy and MDCT in diagnosing grade of esophageal varices as k = 0.882. The presence of ascites, splenic size, and esophageal vein diameter serve as clinically significant predictors of esophageal varices. Splenic size showed a significant difference according to endoscopic grades of EV (esophageal varices) as p = 0.031 as patients with no varices had splenic size of (15.9 ± 1.4) cm, patients with grade I had a mean splenic size of (15.2 ± 8.7) cm, patients with grade II had mean splenic size of (16.9 ± 1.8) cm and patients with grade III had mean splenic size of (18 ± 4.2) cm, while other veins diameters showed increase with advanced grades of EV but with statistically insignificant differences as p > 0.05.

Conclusions
Multidetector CT features of the presence of PSCVs, splenic size, and ascites are accurate predictors of PTHN in either EVs presence or absence. MDCT can be an excellent alternative for patients who are contraindicated for endoscopy. Moreover, it can be potential screening tool for early detection of esophageal varices in very early stage of chronic liver disease and in the early care of patient with varices. MDCT remains the most applicable noninvasive diagnostic tool for patients with portosystemic collaterals.

Abstract

Background

Point-of-care medical information systems (POCMIS) can provide an efficient and effective means of strengthening health systems globally through their encouragement of continued medical education. Using the Consolidated Framework for Implementation Research (CFIR) as a guide, this research provides suggestions for improved implementation of POCMIS in low- and middle-income countries informed by an intervention implemented across public and military hospitals in Lima, Peru.

Methods
Analysis is based on qualitative interviews conducted with 12 Peruvian surgeons across eight public hospitals and one military hospital who received an intervention that provided free access to UpToDate and introduced Google Translate. The post-intervention interviews were transcribed, translated, and analyzed for themes overlapping with CFIR constructs to expose barriers to implementation and suggestions for improved implementation of future interventions.

Results
Barriers included a lack of seniority buy-in and engaged leadership, an overabundance of personal preferences for multiple POCMIS, and a culture of assumption that inhibited open communication regarding access to and use of POCMIS. Suggestions for improved implementation focused on the adaptation of the intervention. Namely, surgeons discussed regionally-specific adaptations as well as adaptations specific to their surgical specialty including visual, rather than written, representation of the information available via POCMIS.

Conclusions
Results indicate necessary adaptations for implementing interventions including POCMIS in LMICs, mimicking much of the implementation science literature on intervention adaptation. In addition to explicit suggestions provided by surgeons, we also suggest actionable steps to adapt to barriers identified in our data. Rapid assessment procedures (RAP) are one established methodological technique useful for assessing organization culture prior to implementation, allowing for necessary cultural adaptations. Dynamic adaption process (DAP) is another useful and established method that breaks implementation into four phases allowing for adaptations based on the initial assessment of the intervention site.
