Imperialism of the Twenty-First Century: A Global Tripartite System
Authors: Azad Rohit , Chakraborty Shouvik 
Published: January 2023

Is imperialism dead? While economists on the Right would readily answer in the affirmative, some even on the Left, like Hardt and Negri, would agree that it is indeed. To be sure, for the latter, global hegemony has taken a different shape, which they call ‘Empire’. But is imperialism, as understood in the classical sense, dead indeed? In varied frameworks of imperialism—world systems, dependency, unequal interdependence—the world has been theorised as constitutive of two parts: capitalist core (global North) and pre/semi-capitalist periphery (global South). This neat classification has been smudged by the emergence of China from the global South as a major economic player in the global economy. We argue its emergence, far from weakening imperialism, is a key factor in explaining today’s imperialism. Imperialism of the twenty-first century constitutes of three, not two, parts—capitalist core, periphery’s core, and periphery’s periphery. JEL Codes: F54; F60
A Tangible Concept of Imperialism: Utsa Patnaik’s Estimates of Colonial Transfers From India
Authors: Iyer Vibha 
Published: January 2023

The earliest work on colonial transfers from India originated in the Drain of wealth theory of the nineteenth century nationalists Dadabhai Naoroji and R. C. Dutt. While the theory displays an implicit understanding of the linking of India’s internal budget and its external accounts to facilitate tax financed transfers to Britain—a feature unique to the colonial economy, it lacked the macroeconomic concepts to make explicit its details. Utsa Patnaik’s methodological framework over the last four decades on imperialism and colonial transfers in particular has contributed significantly towards revealing not only the precise mechanism of extraction of tax financed transfers from India but also formulating accurate estimates of the same. This article focuses on two of Patnaik’s methodological contributions. The first being the use of suitably modified modern macroeconomic concepts in a sovereign economy to lay bare the link between India’s tax revenues and trade surplus and second, the use of Council Bills as a proxy for India’s merchandise surplus which has helped overcome conceptual lacunae in the existing trade data and literature about the colonial period and enabled greater accuracy in the estimation of the transfers.

Neonatal Transport: Before and after Surgery
Authors: Jindal B , Chellani Harish 
Published: January 2023

The transport of a sick neonate can be safely achieved provided adequate resuscitation and stabilization is carried out at the referral centre and are continued during the transport process. It is the responsibility of the physician and nursing staff to allay anxiety and fear of parents by addressing their queries; and simultaneously make necessary arrangements for transport of new born. Neonatal transport system ensures a safe and effective transfer of the sick neonate from the place of birth or diagnosis to a tertiary care centre for the definitive management. The value of various support services (pediatric anesthetist, pediatric radiologist, pediatric surgeon, nursing staff, pathologist and ancillary services) could not be underestimated in these tertiary centers. It has been shown that critically ill neonate can be effectively transported over long distances provided some essential criteria are fulfilled. The ideal transport systems are mobile extensions of tertiary care resources and delivery of highest quality of critical care during transport. The burden of such transport depends upon both the referring physician and tertiary care center.
Care of Neonatal and Preterm Skin. How is it Different?
Authors: Gulati Anu , Nangia Sushma 
Published: January 2023

Skin is a complex structure with unusual functional diversity. It forms a critical physical barrier that not only protects the body but also maintains fluid homeostasis. In addition, it regulates temperature as well as sensation1. The skin of preterm infants is immature and ineffective as an epidermal barrier. Poor epidermal barrier function leads to significant disturbances in temperature regulation, water balance and increased propensity for infections. The preterm skin with its inherent poor microbial defense and its denudation during care multiply the possibilities of microbial invasion and sepsis in this vulnerable population. Topical agents are more rapidly absorbed into infant skin due to deficient intercellular bridges as well as greater body surface area to weight ratio. These inadequacies in its overall functioning need to be kept in mind while managing small neonates in the high-tech neonatal intensive care units.
Risk factors associated with bacteremia with drug-resistant organisms: Review of blood culture results in emergency department of a regional hospital
Authors: Lau Man Ting , Wong Oi Fung 
Published: January 2023

Background: Early antibiotic administration in sepsis improves patient survival. Treatment with antibiotics should cover potential pathogens and should avoid overusing broad-spectrum antibiotics. We have to identify patients who have high risks of infection with drug-resistant organisms. Objectives: A retrospective cohort study was conducted to identify potential risk factors associated with bloodstream infections with drug-resistant organisms to help the choice of empirical antibiotics in the emergency department. Methods: Adult patients with bloodstream infection diagnosed by blood culture in the emergency department in the period of 1 January 2020 to 31 December 2020 were included. Clinical features including chronic medical illnesses, clinical presentation and severity, and patients’ outcomes were identified in the electronic medical records. Bloodstream infection with drug-resistant organisms is defined as positive blood culture with bacteria resistant to either (1) amoxicillin/ clavulanic acid AND ceftriaxone or (2) amoxicillin/ clavulanic acid or ceftriaxone PLUS amikacin or levofloxacin. Univariate and multivariate analyses were conducted to identify risk factors associated with the study outcome. Results: Among 105 patients with bloodstream infection, 17% were caused by drug-resistant organisms. Multivariate analysis showed that age is a risk factor associated with bloodstream infection with drug-resistant organisms (odds ratio: 1.04, 95% confidence interval: 1.0–1.08, p = 0.03). Conclusion: In conclusion, age is a significant risk factor for drug-resistant bloodstream infection in emergency department patients. Further research may be needed to find out the relationship between frailty and infection with drug-resistant organisms.

Published: January 2023

Background: The palpation method of posterior tibial artery cannulation has not yet been compared to ultrasound-guided posterior tibial artery cannulation in adults. This research examined whether using ultrasound to cannulate the posterior tibial artery enhances first-pass cannulation success and lowers total procedure time. Methods: In this randomized controlled experiment, 76 adult patients were included who were undergoing surgery under general anesthesia and required artery cannulation. Cannulation of the posterior tibial artery was performed utilizing either an ultrasound-assisted method (group U) or a palpation method (group P). Data were analyzed for cannulation success on the first attempt, number of cannulation attempts, assessment time, cannulation time, and total procedure time. Results: The P group had a considerably shorter mean assessment time than the U group [14.29 ± 2.79 s vs 20.89 ± 2.70 s; p < .001]. Moreover, cannulation time was substantially longer in the P (29.20 ± 12.60 s) than in the U group (15.90 ± 6.50 s) (p < .001). The total procedure time remained statistically more in the P group than in the U group (p = 0.007). The rate of successful posterior tibial artery cannulation on the first attempt was comparable between the two groups (63.2% in the U and 55.3% in the P group, respectively; p = .484)]. Conclusions: The posterior tibial artery may be a suitable alternative to arterial cannulation for individuals with multiple failed attempts or difficult access. The application of ultrasound during posterior tibial artery cannulation in adult patients is safe and feasible and accompanied by a reduction in cannulation and total procedure time. The rate of first-attempt successful posterior tibial artery cannulation was comparable between the two groups.

Published: January 2023

Background: We aimed to evaluate the impact of heatwaves on daily deaths due to non-accidental, cardiovascular and respiratory causes in the city of Dezful in Iran from 2013 to 2019. Method: We collected daily ambient temperature and mortality and defined 2 types of heatwaves by combining daily temperature ⩾90th in each month of the study period or since 30 years with duration ⩾2 and 3 days. We used a distributed lag non-linear model to study the association between each type of heatwave definition, and deaths due to non-accidental, cardiovascular and respiratory causes with lags up to 13 days. Results: There was no discernible correlation in this area, despite the fact that heatwaves raised the risk of death from cardiovascular causes and lowered the risk from respiratory causes. On the other hand, the risk of total non-accidental mortality on days with the heatwaves is significantly higher than normal days. In main effects, the heatwaves have a significant relationship with the risk of total non-accidental mortality (in the first heatwave definition, Cumulative Excess Risk (CER) in lag0-2 was 10.4 and in second heatwave definition, CER values in lag0, 0-2, and 0-6 were 12.4, 29.2, and 38.8 respectively). Also, in added effects, heatwaves have a significant relationship with the risk of total non-accidental mortality (in the first heatwave definition, CER in lag0 and 0-2 were 1.79 and 4.11 and in the second heatwave definition, CER values in lag0, 0-2, and 0-6 were 7.76, 18.35 and 24.87 respectively). In addition, heatwaves appeared to contribute to a cumulative excess risk of non-accidental death among the male group as well as the older adults. Conclusion: However, the results showed that heatwaves could have detrimental effects on health, even in populations accustomed to the extreme heat. Therefore, early warning systems which monitor heatwaves should provide the necessary warnings to the population, especially the most vulnerable groups.

Aims: Foetuses exposed to smoking during pregnancy are disadvantaged due to numerous adverse obstetric outcomes. This study aimed to examine 1) inequality in maternal smoking between subgroups of pregnant women and 2) significant risk factors of maternal smoking. Methods: Data were collected from Danish registries. Trends in maternal smoking within each study period, T1 (2000–2002) and T2 (2014–2016), were investigated by Poisson regression calculating prevalence proportion ratios, and trends between study periods were studied by adding an interaction term. The significance of risk factors for maternal smoking (low age, low education, living alone and having a moderate/severe mental health condition) were studied by interaction analysis on the additive scale. Results: The prevalence of maternal smoking decreased from 21% in 2000 to 7% in 2016. Decreases were found in all subgroups of maternal age, cohabitation status, educational level and mental health condition. However, large differences in smoking prevalence between subgroups were found, and inequality in maternal smoking increased from 2000 to 2016. The probability of maternal smoking increased with the addition of risk factors, and positive additive interactions were found for almost all combinations of multiple risk factors. Conclusions: Our results provide knowledge on risk factors and increasing levels of inequality in maternal smoking which points to a need for targeted interventions in relation to maternal smoking for subgroups of pregnant women in future smoking cessation programmes and in antenatal care.
Learning curves in robot-assisted minimally invasive liver surgery at a high-volume center in Denmark: Report of the first 100 patients and review of literature

Published: January 2023

Background and objective: Minimally invasive liver surgery is evolving worldwide, and robot-assisted liver surgery (RLS) can deliver obvious benefits for patients. However, so far no large case series have documented the learning curve for RLS. Methods: We conducted a retrospective study for robotic liver surgery (RLS) from June 2019 to June 2022 where 100 patients underwent RLS by the same surgical team. Patients’ variables, short-term follow-up, and the learning curve were analyzed. A review of the literature describing the learning curve in RLS was also conducted. Results: Mean patient age was 63.1 years. The median operating time was 246 min and median estimated blood loss was 100 mL. Thirty-two patients underwent subsegmentectomy, 18 monosegmentectomies, 25 bisegmentectomies, and 25 major hepatectomies. One patient (1.0%) required conversion to open surgery. Five patients (5%) experienced postoperative major complications, and no mortalities occurred. Median length of hospital stay was 3 days. R0 resection was achieved in 93.4% of the malignant cases. The learning curve consisted of three stages; there were no significant differences in operative time, transfusion rate, or complication rate among the three groups. Postoperative complications were similar in each group despite an increase in surgical difficulty scores. The learning effect was highlighted by significantly shorter hospital stays in cohorts I, II, and III, respectively. The included systematic review suggested that the learning curve for RLS is similar to, or shorter, than that of laparoscopic liver surgery. Conclusions: In our experience, RLS has achieved good clinical results, albeit in the short term. Standardization of training leads to increasing proficiency in RLS with reduced blood loss and low complication rates even in more advanced liver resections. Our study suggests that a minimum of 30 low-to-moderate difficulty robotic procedures should be performed before proceeding to more difficult resections.
Pediatric anterior cruciate ligament tears and associated lesions: Epidemiology, diagnostic process, and imaging
Authors: Duart Julio , Rigamonti Luca , Bigoni Marco , Kocher Mininder S 
Published: January 2023

The incidence of anterior cruciate ligament injuries in skeletally immature patients has increased in recent years. The gold standard treatment of this type of trauma in children is not yet established. Conservative management may underestimate the risk of new meniscal and chondral tears; on the other hand, a more interventional approach may expose the patient to iatrogenic damage to the growth plate. A correct approach to the skeletally immature patient with knee trauma is therefore essential to guide the decision-making process. This review article aims to present an update on the epidemiology and diagnostic process of pediatric patients with anterior cruciate ligament tears and possible associated injuries.

Application of Nonlinear Lamb Wave Mixing Method for Residual Stress Measurement in Metal Plate
Authors: Jiao Jingpin , Li Li , Gao Xiang , Cheng Quan , He Cunfu , Wu Bin 
Published: January 2023

AbstractHarmonic nonlinear ultrasound can offer high sensitivity for residual stress measurements; however, it cannot be used for local stress measurements at a point in space and exhibits nonlinear distortions in the experimental system. This paper presents a feasibility study on the measurement of residual stress in a metal plate using a nonlinear Lamb wave-mixing technique. The resonant conditions for two Lamb waves to generate a mixing frequency wave are obtained via theoretical analysis. Finite element simulations are performed to investigate the nonlinear interactions between the two Lamb waves. Results show that two incident A0 waves interact in regions of material nonlinearity and generate a rightward S0 wave at the sum frequency. Residual stress measurement experiments are conducted on steel plate specimens using the collinear Lamb wave-mixing technique. By setting different delays for two transmitters, the generated sum-frequency component at different spatial locations is measured. Experimental results show that the spatial distribution of the amplitude of the sum-frequency component agrees well with the spatial distribution of the residual stress measured using X-rays. The proposed collinear Lamb wave-mixing method is effective for measuring the distribution of residual stress in metal plates.

Authors: Kuang Renzhao , Li Shun , Wang Yuanchuan 
Published: January 2023

Abstract
Background
Primary cerebral epithelioid angiosarcoma (PCEA) is a rare malignant tumor of the central nervous system. To the best of our knowledge, only three cases have been reported in the English language literature thus far.

Case presentation
Here, we report a fourth case in a 73-year-old man admitted for headache. Radiological examination revealed a mass in the right occipital lobe, which was removed by right occipital craniotomy. Histopathological examination revealed epithelioid angiosarcoma. The patient received radiotherapy after resection but survived for only nine months due to recurrence of the tumor and his declining further surgery.

Conclusions
In this report, we add to the knowledge base on this exceedingly rare tumor, review the small number of relevant cases published previously, and analyze and summarize the clinical and pathological characteristics, treatment options and prognosis of this cancer.
Arabic translation and validation of a pediatric sleep questionnaire to assess the prevalence of sleep-disordered breathing among Saudi pre-school children
Authors: Masoud Ahmed I , Mosli Rana H 
Published: January 2023

Abstract
Objectives
(1) To translate to Arabic a validated pediatric sleep questionnaire, (2) To assess the validity and reliability of the translated questionnaire, and (3) To assess the prevalence of sleep-disordered breathing (SDB) among a group of pre-school children in Jeddah, Saudi Arabia.

Methods
Using forward and back-translation, a set of 6 hierarchically arranged questions that comprise the Gozal sleep questionnaire was translated into Arabic. Validity was assessed using face validity and content validity for consistency and clarity, using both item-level and scale-level content validity indices (I-CVI, S-CVI). Consent forms were sent to 1783 mothers recruited from 8 different pre-schools in Jeddah between October 2017 and April 2018, and 209 signed and returned the consent forms. Out of this sample, 34 mothers were contacted to assess internal consistency using Cronbach's alpha, and test-retest reliability using Interclass correlation coefficient (ICC). Finally, all 209 mothers were contacted to answer the questionnaire to obtain the prevalence of SDB.

Results
Using face validity and content validity, the translated questionnaire proved to be valid with perfect I-CVI and S-CVI. Internal consistency (Cronbach’s Alpha 0.64–0.89) and test-retest reliability (ICC=0.87, p<0.001) showed the translated questionnaire to have good to favorable reliability. Depending on the severity of SDB, the prevalence of SDB was 7.7%, 5.7%, and 3.8% for mild, moderate and severe cut-off values respectively.

Conclusion
A validated pediatric sleep questionnaire to assess SDB was translated into Arabic and the translation proved to be valid and reliable. The prevalence of SDB was found to be very comparable to other areas in the world.
Early life climate and adulthood mental health: how birth seasonality influences depressive symptoms in adults
Authors: Zhou Hao , Peng-Li Danni , Chen Juan , Sun Dong , Wan Bin 
Published: January 2023

Abstract
Background
Early life in-utero can have long-term influence on the mental health status of individuals in adulthood, such as depression. Age, gender, socio-economic status, education, and geography are demographic factors shown to be particularly vulnerable towards the development of depressive symptoms. In addition, climate risks on depression include sunlight, rain, and temperature. However, whether climate factors in early life have a long-term influence on depression related to demographic vulnerability remains unknown. Here, the present study explored the association between birth seasonality and adulthood depressive symptoms.

Methods
We employed data from the project of Chinese Labour-forces Dynamic Survey (CLDS) 2016, containing the epidemiological data of depressive symptoms with a probability proportional to size cluster and random cluster sampling method in 29 provinces of China. A final sample size of 16,185 participants was included. Birth seasonality included spring (March, April, and May), summer (June, July, and August), autumn (September, October, and November), and winter (December, January, and February).

Results
We found that born in Autumn peaked lowest rate of having depressive symptoms (16.8%) and born in Summer (vs. Autumn) had a significant higher ratio (OR = 1.14, 95%CI = 1.02, 1.29) when controlling for demographic variables. In addition, demographic odds ratio of having depressive symptoms differed between people born in different seasons, particular for age and geography.

Conclusion
Our findings suggest that birth seasonality influences the sensitive link of depressive symptoms with age and geography. It implicates early life climate environment may play a role in the development of adulthood depressive symptoms.
