Effect of biochar addition on legacy phosphorus availability in long-term cultivated arid soil
Authors: Alotaibi Khaled D. , Arcand Melissa , Ziadi Noura 
Published: September 2021

AbstractBackgroundContinuous application of phosphorus (P) nutrient in association with its low recovery results in large amounts of P being accumulated in soil in different forms. Use of biochar can be a possible means to mobilize soil legacy P and increase its bioavailability. Therefore, the aim of this study was to identify the potential impact of a range of biochar types on P fractions in a long-term cultivated arid soil with high legacy P content.MethodologyThe soil was treated with biochar produced from four feedstock sources (BFS): sewage sludge (SSB), olive mill pomace (OPB), chicken manure (CMB), and date palm residues (DRB) pyrolyzed at 300, 500, or 700 °C in addition to an untreated control. The soil biochar mixture was incubated for 1 month followed by soil P fractionations using sequential chemical extraction to separate soil P into: labile (Resin-Pi, NaHCO3-Pi, NaHCO3-Po), moderately labile (NaOH-Pi, NaOH-Po), and non-labile (HCl-Pi and Residual-P) pools.ResultsBiochar addition clearly influenced most of the soil P fractions; however, the extent of this effect greatly varied depending on BFS and pyrolysis temperature (PT). The most evident biochar impact was observed with labile P pool, with the greatest increase being observed in NaHCO3-Pi fraction in most biochar treatments. Irrespective of PT, SSB and CMB were the most effective biochar type in increasing labile inorganic P; the SSB and CMB increased Resin-Pi by 77 and 206% and NaHCO3-Pi by 200 and 188%, respectively. In contrast, DRB made no changes in any P fraction. Differences in effects of biochar types on labile P is presumably related to the higher content of P in biowaste-based biochar compared to plant-based biochar which have much lower P content. The SSB, CMB, and OPB produced at low temperature reduced HCl-Pi content, indicating that these biochars may have stimulated organic matter decomposition and thereby dissolution of non-labile Ca-associated P to labile P forms.ConclusionOverall, biochar addition appeared to be an effective approach in enhancing legacy P availability in arid soil. However, further studies are necessary to verify these findings in the presence of plant and for a longer period.Graphic abstract

Authors: Youssef Dalal , Abou-Abbas Linda , Hassan Hamad 
Published: September 2021

Abstract
Background
Utilizing community pharmacists (CPs) as immunizers has being adopted in various countries as approach to boost influenza vaccination coverage. Our study aims to explore the Lebanese CPs’ willingness to administer influenza vaccine, and to identify factors associated with this willingness.

Methods
This is a web-based, cross-sectional study, conducted over 2 months, from the 1st of November to the end of December 2020. Self-reported data were collected electronically from Lebanese CPs through an anonymous, questionnaire using google form. The collected data were analyzed using the statistical software SPSS (Statistical Package for Social Sciences). Bivariate and multivariable analyses were performed to examine factors associated with the willingness of CPs to administer influenza vaccine.

Results
A total of 412 CPs participated in this survey of which 76.9% are willing to administer influenza vaccines. More than 90% of them had a good overall knowledge score and 88.8% of CPs showed a positive overall attitude score, particularly towards involvement of CPs in influenza vaccine provision. Their willingness to administer vaccine was positively associated with the younger age (aOR = 3.12 with 95% CI (1.597–4.040)), higher education level (aOR = 2.02 with 95% CI (1.093–3.741)), previous experience in immunization (aOR = 2.72 with 95% CI (1.320–5.627)) and urbanicity of pharmacy (aOR = 1.542 with 95% CI (1.219–4.627)). Extensive working hours (aOR = 2.34 with 95% CI (1.131–4.845)), working in pharmacies that are operating round-the-clock, showing positive attitude towards immunization (aOR = 3.01 with 95% CI (1.872–6.422)) and towards provision of influenza vaccines (aOR = 13.72 with 95% CI (13.721–38.507)) were also positively associated to this willingness. Conversely, patient privacy (aOR = 0.55 with 95% CI (0.079–0.983)), time and cost for professional development (aOR = 0.55 with 95% CI (0.172–0.918)), limited patient’s trust (aOR = 0.39 with 95% CI (0.203–0.784)), financial remuneration (aOR = 0.18 with 95% CI (0.088–0.377)), and requirement of formal certification in vaccine administration (aOR = 0.07 with 95% CI (0.020–0.279)) were negatively associated to this willingness.

Conclusion
Addressing the unearthed concerns related to utilizing CPs as influenza immunizers through a concerted effort is a key to success in any future implementation of vaccination services in pharmacies.

Abstract
Background
Perivascular epithelioid cell neoplasm (PEComa) in a child is very rare. We herein report the first malignant case of PEComa developing in the liver of a pediatric patient.

Case presentation
A 10-year-old boy visited a private clinic with prolonged fever of unknown etiology. Abdominal ultrasonography was performed to evaluate the fever’s origin, revealing a large tumor in the liver. He was thus referred to a nearby hospital to investigate the tumor further. Enhanced computed tomography (CT) showed a 6.8 × 5.9 × 10.5-cm solid lesion on S4 and S5. On magnetic resonance imaging (MRI), the tumor had a low signal intensity on T1 imaging and high signal intensity on T2 imaging, with partial diffusion restriction. 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) showed a marked uptake in the mass lesion with no evidence of metastasis. The patient was negative for all tumor markers, including AFP, CEA and PIVKA-II. The results of a needle biopsy suggested hepatocellular carcinoma. The tumor’s rapid growth suggested malignancy. Hepatic segmentectomy (S4 + S5 + S8) was performed. The tumor was resected en bloc with a margin. Microscopically, the tumor showed atypical spindle, polygonal or oval-shaped cells with a high nuclear grade, and vascular invasion. Immunohistochemistry was positive for alpha-smooth muscle antigen (α-SMA), human melanin black-45 (HMB-45) and melan A. The pathological diagnosis was malignant PEComa. In the 6 months after surgery, the patient complained of shoulder pain. MRI showed a dumbbell-shaped tumor at the 2nd thoracic vertebrae, which was confirmed to be bone metastasis of PEComa. After chemotherapy, including ifosfamide and doxorubicin, vertebrectomy was performed. Two years later, thoracoabdominal CT showed a 10-cm solid mass occupying the pelvis and a 15-mm nodule in the middle lobe of the right lung. Under a diagnosis of peritoneal and lung metastases, they were surgically removed and metastasis of PEComa was pathologically confirmed. Four months after the 2nd relapse, pelvic metastasis appeared again and mTOR (mammalian target of rapamycin) inhibitor was initiated. To our knowledge, this is the first report of malignant hepatic PEComa in a pediatric patient.

Conclusion
Although extremely rare, malignant hepatic PEComa can develop in a child.

Published: September 2021

Abstract
Background
Previous studies have shown that stigma is a major barrier to participation in psychiatric research and that individuals who participate in psychiatric research may differ clinically and demographically from non-participants. However, few studies have explored research recruitment and retention challenges in the context of personality disorders.

Aim
To provide an analysis of the factors affecting participant recruitment and retention in a study of borderline personality disorder among general psychiatric inpatients.

Methods
Adult inpatients in a tertiary psychiatric hospital were approached about participating in a cross-sectional study of borderline personality disorder. Recruitment rates, retention rates, and reasons for declining participation or withdrawing from the study were collected. Demographic characteristics were compared between participants and non-participants and between patients who remained in the study and those who withdrew.

Results
A total of 71 participants were recruited into the study between January 2018 and March 2020. Recruitment and retention rates were 45% and 70%, respectively. Lack of interest was the most commonly cited reason for non-participation, followed by scheduling conflicts and concerns regarding mental/physical well-being. Age and sex were not predictors of study participation or retention.

Conclusions
More research is needed to explore patients’ perspectives and attitudes towards borderline personality disorder diagnosis and research, determine effects of different recruitment strategies, and identify clinical predictors of recruitment and retention in personality disorder research.
Dexmedetomidine as an adjuvant to bupivacaine in ultrasound-guided serratus anterior plane block in patients undergoing video-assisted thoracoscopic surgeries
Authors: Menshawi Mohammed Abdelsalam , Fahim Hany Magdy 
Published: September 2021

Abstract
Background
The purpose of this study was the assessment of the analgesic and hemodynamic implications of dexmedetomidine used as an additive to bupivacaine in ultrasound-guided serratus anterior plane (SAP) block for patients undergoing video-assisted thoracoscopic surgeries (VATS ) under general anesthesia.

Results
The hemodynamic stability was maintained perioperatively with no significant difference of MBP and HR recordings between the two study groups (P > 0.05). The time to 1st postoperative analgesic demand was significantly longer in group BD than in group B (P < 0.05). The postoperative total nalbuphine and rescue ketorolac requirements were significantly lower in group BD than in group B (P < 0.05). The VAS scores were significantly lower in group BD at 8th and 12th h postoperatively than in group B, with no significant difference at 0–6 h and 18–24 h postoperatively (P > 0.05). Ramsay sedation scores were significantly higher in the group BD than in group B in the initial 1st h after surgery (P < 0.05) with no significant difference at the subsequent postoperative recordings (P > 0.05).

Conclusion
Using dexmedetomidine (0.5 μg/kg) as an additive to bupivacaine for SAP block prolongs the duration of postoperative analgesia and reduces the postoperative analgesic requirements in the 1st 24 h after VATS without any significant side effects.

Feasibility analysis of GNSS-based ionospheric observation on a fast-moving train platform (GIFT)
Authors: Yu Shiwei , Liu Zhizhao 
Published: September 2021

AbstractThe ionospheric effect plays a crucial role in the radio communications. For ionospheric observing and monitoring, the Global Navigation Satellite System (GNSS) has been widely utilized. The ionospheric condition can be characterized by the Total Electron Contents (TEC) and TEC Rate (TECR) calculated from the GNSS measurements. Currently, GNSS-based ionospheric observing and monitoring largely depend on a global fiducial network of GNSS receivers such as the International GNSS Service (IGS) network. We propose a new approach to observe the ionosphere by deploying a GNSS receiver on a Hong Kong Mass Transit Railway (MTR) train. We assessed the TECR derived from the MTR-based GNSS receiver by comparing it with the TECR derived from a static GNSS receiver. The results show that the Root-Mean-Squares (RMS) errors of the TECR derived from the MTR-based GNSS receiver is consistently approximately 23% higher than that derived from the static GNSS receiver. Despite the increased error, the findings suggest that the GNSS observation on a fast-moving platform is a feasible approach to observe the ionosphere over a large region in a rapid and cost-effective way.
Optimal Thyroid Hormone Replacement
Authors: Jonklaas Jacqueline 
Published: September 2021

AbstractHypothyroidism is a common endocrinopathy, and levothyroxine is frequently prescribed. Despite the basic tenets of initiating and adjusting levothyroxine being agreed on, there are many nuances and complexities to consistently maintaining euthyroidism. Understanding the impact of patient weight and residual thyroid function on initial levothyroxine dosage and consideration of age, comorbidities, thyrotropin goal, life stage, and quality of life as levothyroxine is adjusted can be challenging and continually evolving. Because levothyroxine is a lifelong medication, it is important to avoid risks from periods of overtreatment or undertreatment. For the subset of patients not restored to baseline health with levothyroxine, causes arising from all aspects of the patient’s life (coexistent medical conditions, stressors, lifestyle, psychosocial factors) should be broadly considered. If such factors do not appear to be contributing, and biochemical euthyroidism has been successfully maintained, there may be benefit to a trial of combination therapy with levothyroxine and liothyronine. This is not supported by the majority of randomized clinical trials, but may be supported by other studies providing lower-quality evidence and by animal studies. Given this discrepancy, it is important that any trial of combination therapy be continued only as long as a patient benefit is being enjoyed. Monitoring for adverse effects, particularly in older or frail individuals, is necessary and combination therapy should not be used during pregnancy. A sustained-release liothyronine preparation has completed phase 1 testing and may soon be available for better designed and powered studies assessing whether combination therapy provides superior therapy for hypothyroidism.
Is Parental Divorce Homogamy Associated With a Higher Risk of Separation From Cohabitation and Marriage?

Published: September 2021

Abstract
Numerous studies have shown that parental divorce is associated with an increase in adult children's divorce risk. We extend this literature by assessing how parental divorce on both sides of a couple is related to their partnership dynamics, specifically, whether there is parental divorce homogamy and whether a history of parental divorce for both partners is associated with increased dissolution risks for cohabiting and married unions. We use Finnish Census Panel data on 28,021 cohabiting and marital partnerships to conduct event-history models that follow individuals between ages 18 and 45. Findings show substantial parental divorce homogamy. Children with experience of parental divorce have 13% greater odds of cohabiting with and 17% greater odds of marrying a fellow child of divorcees, compared with those whose parents have not divorced. Moreover, contrary to evidence from the United States and Norway, our findings for Finland support an additive—rather than multiplicative—association between parental divorce homogamy and union dissolution. Parental divorce homogamy increases offspring's union dissolution risk by 20% for cohabitation and 70% for marriage, compared with couples for whom neither partner's parents are divorced. In Finland, the sizes of these associations are notably weaker than in the United States and Norway, likely because cohabitation and separation are more widespread and socially accepted in Finland, and an expansive welfare state buffers the socioeconomic consequences of divorce.
Ocellar spatial vision in Myrmecia ants
Authors: Penmetcha Bhavana , Ogawa Yuri , Ryan Laura A. , Hart Nathan S. , Narendra Ajay 
Published: September 2021

ABSTRACT
In addition to compound eyes, insects possess simple eyes known as ocelli. Input from the ocelli modulates optomotor responses, flight-time initiation, and phototactic responses – behaviours that are mediated predominantly by the compound eyes. In this study, using pattern electroretinography (pERG), we investigated the contribution of the compound eyes to ocellar spatial vision in the diurnal Australian bull ant Myrmecia tarsata by measuring the contrast sensitivity and spatial resolving power of the ocellar second-order neurons under various occlusion conditions. Furthermore, in four species of Myrmecia ants active at different times of the day, and in European honeybee Apis mellifera, we characterized the ocellar visual properties when both visual systems were available. Among the ants, we found that the time of activity had no significant effect on ocellar spatial vision. Comparing day-active ants and the honeybee, we did not find any significant effect of locomotion on ocellar spatial vision. In M. tarsata, when the compound eyes were occluded, the amplitude of the pERG signal from the ocelli was reduced 3 times compared with conditions when the compound eyes were available. The signal from the compound eyes maintained the maximum contrast sensitivity of the ocelli as 13 (7.7%), and the spatial resolving power as 0.29 cycles deg−1. We conclude that ocellar spatial vison improves significantly with input from the compound eyes, with a noticeably larger improvement in contrast sensitivity than in spatial resolving power.

Aims: The aim of the study was to reveal the variability in soil properties influencing pigeonpea (Cajanus cajana L.) seed yield under semi-arid rainfed condition. Methods: Soils were initially classified into series level and further these series were divided into soil-phase units. For two site years viz., 2018-19 and 2019-20, surface soil samples from each soil-phase unit were collected before sowing of pigeonpea and subsequently crop growth parameters at critical stages were recorded. Results: The principal component analysis with varimax rotation resulted in seven components for both the site years, having eigenvalues greater than one, explained more than 80% of the variability. The step wise linear regression analysis showed that the pigeonpea seed yield was linearly correlated with PC3 (p<0.01), PC4 (p<0.01) and PC7 (p<0.05) of soil properties with R2 = 0.679, during 2018-19. Whereas, during 2019-20, the seed yield was linearly correlated with PC1 (p<0.01), PC3 (p<0.01) and PC6 (p<0.05) with R2 = 0.677. In site year 1, the available P2O5, Fe, Zn, S, Cu, number of pods, surface soil moisture determined the yield. In site year 2, the available K2O, P2O5, Fe, Zn, S, clay, CEC and available water content determined the yield. All these variables together explain variability in yield.

Published: September 2021

Background: Due to lack of equipment for directly measuring crystal morphology, there has been little research on lenticular astigmatism. The purpose of this study was to accurately explore the correlation between internal astigmatism and lens astigmatism in patients with ametropia. Methods: This is a cross-sectional study conducted in the Affiliated Hospital of North Sichuan Medical College, China, in September 2020. Diopter values (refractive astigmatism, RA) of patients with ametropia was recorded, and the corneal and lens biological parameters were measured by CASIA2 (corneal/anterior segment optical correlation tomography analyzer). Biometric parameters, including the total corneal astigmatism (total corneal astigmatism, TCA), anterior and posterior curvature radius of the lens (anterior curvature radius of the lens, ACL; posterior curvature radius of the lens, PCL), internal astigmatism (internal astigmatism, IA), anterior and posterior astigmatism of the lens (anterior astigmatism of the lens, AAL; posterior astigmatism of the lens, PAL) were measured. Grouping and comparisons were made according to gender and age. Results: In total, 151 participants (293 eyes) were included in the analysis. There were significant ( P<0.05) differences in the IA ( Z=-2.194, P=0.028) according to gender, but not in the other parameters. By age group, there were statistically significant differences in the TCA ( H=10.609, P=0.005), IA ( F=3.722, P=0.025), and PAL ( H=8.254, P=0.016), but not in the others. The IA was positively correlated with the age ( r=0.155, P=0.008), RA ( r=0. 534, P<0.001), AAL ( r=0.308, P<0.001), and was negatively correlated with the TCA ( r=-0.244, P<0.001). The regression equation between the IA and AAL was: Y (IA) =-0.626 +0.447 X (AAL). Conclusions: Internal astigmatism is mainly related to the anterior astigmatism of the lens, and the higher the anterior astigmatism of the lens, the higher the internal astigmatism; At the same time, internal astigmatism increases with age.
