Specialist facilities for children are still unavailable in some Sub-Saharan African contexts. It is the case of pediatric urology, whose recent advances are still largely unshared. Prenatal diagnosis of urinary abnormalities (CAKUT) is largely unknown. Early recognition and referral of Undescended testis (UDT), Hypospadia, bladder exstrophy epispadias complex, ambiguous genitalia, stone disease, and tumours are uncommon in rural areas. Missed diagnosis is not uncommon and delayed management is associated with poor outcomes. We present a cross-sectional, descriptive study about the epidemiology of Pediatric urological admissions to three sub-Saharan East African Hospitals. All the urological cases between 0-18 years referred to three distinct East African Hospitals over 124 weeks were considered. Prevalence of different groups of diseases, age, and mode of presentation were reported. We found 351 cases (M/F 127/24) out of 2543 surgical referrals (13%). Seventy percent of cases were Hypospadias and UDT. Fifty percent of UDT were beyond 6, and most Hypospadias were between 4 and 7 yrs. CAKUT had a very low prevalence (4.84%), and about 50% of Wilms Tumours came too late to be resectable. In many African contexts, urology is still a tiny portion of the pediatric surgical workload compared to the 25% of European and American reports. There are also differences in the epidemiology of genitourinary conditions. A hidden burden of diseases may be presumed, remaining undiagnosed due to the shortage of specialist facilities.

Sorafenib plus transarterial chemoembolization vs sorafenib alone for patients with advanced hepatocellular carcinoma: A systematic review and meta-analysis
Authors: Yang Hong-Jie , Ye Bin , Liao Jia-Xu , Lei Lei , Chen Kai
Published: January 2024

BACKGROUND

Although the past decade has seen remarkable advances in treatment options for hepatocellular carcinoma (HCC), the dismal overall prognosis still envelops HCC patients. Several comparative trials have been conducted to study whether transarterial chemoembolization (TACE) could improve clinical outcomes in patients receiving sorafenib for advanced HCC; however, the findings have been inconsistent.

AIM

To study the potential synergies and safety of sorafenib plus TACE vs sorafenib alone for treating advanced HCC, by performing a systematic review and meta-analysis.

METHODS

This study was conducted following the PRISMA statement. A systematic literature search was conducted using the Cochrane Library, Embase, PubMed, and Web of Science databases. Data included in the present work were collected from patients diagnosed with advanced HCC receiving sorafenib plus TACE or sorafenib alone. Data synthesis and meta-analysis were conducted using Review Manager software.

RESULTS

The present study included 2780 patients from five comparative clinical trials (1 was randomized control trial and 4 were retrospective studies). It was found that patients receiving sorafenib plus TACE had better prognoses in terms of overall survival (OS), with a combined hazard ratio (HR) of 0.65 [95% confidence interval (95%CI): 0.46–0.93, P = 0.02, n = 2780]. Consistently, progression free survival (PFS) and time to progression (TTP) differed significantly between the sorafenib plus TACE arm and sorafenib arm (PFS: HR = 0.62, 95%CI: 0.40–0.96, P = 0.03, n = 443; TTP: HR = 0.73, 95%CI: 0.64-0.83, P < 0.00001, n = 2451). Disease control rate (DCR) was also significantly increased by combination therapy (risk ratio = 1.36, 95%CI: 1.02-1.81, P = 0.04, n = 641). Regarding safety, the incidence of any adverse event (AE) was increased due to the addition of TACE; however, no significant difference was found in grade ≥ 3 AEs.

CONCLUSION

The combination of sorafenib with TACE has superior efficacy to sorafenib monotherapy, as evidenced by prolonged OS, PFS, and TTP, as well as increased DCR. Additional high-quality trials are essential to further validate the clinical benefit of this combination in the treatment of advanced HCC.

Published: January 2024

Off-highway segment (OHW) is to meet the new emission norms of CEV BS V/Trem-V legislations. For new emission norms numerous development and validation activities need to be carried out to achieve the results with in a very short development time. The conventional Mechanical Fuel Injection system is being replaced with Common Rail Injection system and with advanced Exhaust Gas after treatment system like DOC, DPF & SCR etc. The development approach of all work package at engine/vehicle level requires huge efforts in terms of calibration and validation to meet the emission standards of various end implements specific to the Indian market.

Diesel Particulate Filter has become a necessary After treatment system in OHW segments to meet new emission legislation especially for the reduction of particulate matter, wherein DPF helps in accumulation of the particulate matter. At a certain period of engine running, Particulate matter will be loaded in the DPF to its maximum extent which in turn increases the backpressure of the system. Accumulation of particulate matter needs to be monitored and detected accurately to trigger DPF regeneration at certain interval to burn off the accumulated particulate matter. Soot loading and burning is dependent on various factors like exhaust mass flow, temperature, catalyst specification and the end implements in the field.

The Load collective of OHW segment is diverse considering all the different implements, also OEM’s Strategy of common approach for all implements increases the complexity of calibration/validation of the system. This paper intends to present an approach of DPF calibration to meet the challenges of all field implements with the common calibration, focusing on thermal management, soot load correlation and further defining software strategies specific to regional requirements. This will ensure safe DPF operations in all field implements like ploughing, rotavator, cultivator, harvester, disc harrow, empty trolly etc.
Corrosion Behavior of Bare & Organic Coated ADC-12 Used for Heat Sink Enclosure of on-Board Charger
Authors: Bhatt Srishti , Bali Shirish , Rao Bhaskar
Published: January 2024

The automotive sector trend is moving towards vehicle electrification that provides great energy and environmental implications. However, Electrical Vehicles (EVs) are facing challenges in term of charging, driving range and life cycle with respect to existing vehicles. One of the key components in EV which is responsible for charging is On-Board Charger (OBC). OBCs are mainly used in converting DC power from battery pack to AC power and contains different power-electronic devices such as MOSFETs, diodes, magnetics etc. Heat-sinks are used to transfer the heat generated by these electronics and also as an enclosure to accommodate the electronics. Aluminum based alloy-ADC-12 generally used for manufacturing of OBC-enclosure due to its light weight, easy castability and good thermal conductivity. Although ADC-12 aluminum alloy has high corrosion resistance, specific environment condition or situation may accelerate corrosion with extended storage in rainy and salty environments. Normally, mounting position of OBC in vehicle is generally below powertrain system either parallel or tilted to ground surface. Due to this during rainy season there are chances of prolonged water accumulation at fins of ADC-12 enclosure which results into corrosion of ADC-12. Thus, to protect OBC-enclosure from corrosion, organic (Acrylic resin with Al2O3 / TiO2 pigments) coating through Cathodic Electro Deposition (CED) process has been developed and comparative evaluation of corrosion resistance of coated and bare ADC-12 has been studied in this work. Corrosion rate was measured by performing immersion test in 3.5 wt. % NaCl solution for 500 hours. Visual inspection, SEM-EDS analysis and weight loss measurement was used to compare the performance of coated and bare samples after immersion test. Uniform corrosion was observed in case of bare-ADC-12 while negligible corrosion was observed in case of coated samples after immersion test of 500 hours. SEM-EDS analysis indicates the localized corrosion initiated from the intermetallic (rich in Si and Mn, Fe, Cu) and formed their oxides. At exposed region initially Al forms protective alumina (Al2O3) layer but after certain time cracking of layer occurs and further corrosion takes place. Corrosion rate by weight loss technique measurement show that bare ADC-12 enclosure corroded approximate three times faster than coated-samples.

Anti-N-methyl-D-aspartate receptor-associated encephalitis: A review of clinicopathologic hallmarks and multimodal imaging manifestations
Authors: Beutler Bryce David , Moody Alastair E , Thomas Jerry Mathew , Sugar Benjamin Phillip , Ulanja Mark B , Antwi-Amoabeng Daniel , Tsikitas Lucas Anthony
Published: January 2024

Anti-N-methyl-D-aspartate receptor-associated encephalitis (NMDARE) is a rare immune-mediated neuroinflammatory condition characterized by the rapid onset of neuropsychiatric symptoms and autonomic dysfunction. The mechanism of pathogenesis remains incompletely understood, but is thought to be related to antibodies targeting the GluN1 subunit of the NMDA receptor with resultant downstream dysregulation of dopaminergic pathways. Young adults are most frequently affected; the median age at diagnosis is 21 years. There is a strong female predilection with a female sex predominance of 4:1. NMDARE often develops as a paraneoplastic process and is most commonly associated with ovarian teratoma. However, NMDARE has also been described in patients with small cell lung cancer, clear cell renal carcinoma, and other benign and malignant neoplasms. Diagnosis is based on correlation of the clinical presentation, electroencephalography, laboratory studies, and imaging. Computed tomography, positron emission tomography, and magnetic resonance imaging are essential to identify an underlying tumor, exclude clinicopathologic mimics, and predict the likelihood of long-term functional impairment. Nuclear imaging may be of value for prognostication and to assess the response to therapy. Treatment may involve high-dose corticosteroids, intravenous immunoglobulin, and plasma exchange. Herein, we review the hallmark clinicopathologic features and imaging findings of this rare but potentially devastating condition and summarize diagnostic criteria, treatment regimens, and proposed pathogenetic mechanisms.
From strength to precision: A systematic review exploring the clinical utility of 7-Tesla magnetic resonance imaging in abdominal imaging
Authors: Perera Molligoda Arachchige Arosh S , Teixeira de Castro Gonçalves Ortega Ana Claudia , Catapano Federica , Politi Letterio S , Hoff Michael N
Published: January 2024

BACKGROUND

After approval for clinical use in 2017 early investigations of ultra-high-field abdominal magnetic resonance imaging (MRI) have demonstrated the feasibility as well as diagnostic capabilities of liver, kidney, and prostate MRI at 7-Tesla. However, the elevation of the field strength to 7-Tesla not only brought advantages to abdominal MRI but also presented considerable challenges and drawbacks, primarily stemming from heightened artifacts and limitations in Specific Absorption Rate, etc. Furthermore, evidence in the literature is relatively scarce concerning human studies in comparison to phantom/animal studies which necessitates an investigation into the evidence so far in humans and summarizing all relevant evidence.

AIM

To offer a comprehensive overview of current literature on clinical abdominal 7T MRI that emphasizes current trends, details relevant challenges, and provides a concise set of potential solutions.

METHODS

This systematic review adheres to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A PubMed search, utilizing Medical Subject Headings terms such as "7-Tesla" and organ-specific terms, was conducted for articles published between January 1, 1985, and July 25, 2023. Eligibility criteria included studies exploring 7T MRI for imaging human abdominal organs, encompassing various study types (in-vivo /ex-vivo , method development, reviews/meta-analyses). Exclusion criteria involved animal studies and those lacking extractable data. Study selection involved initial identification via title/abstract, followed by a full-text review by two researchers, with discrepancies resolved through discussion. Data extraction covered publication details, study design, population, sample size, 7T MRI protocol, image characteristics, endpoints, and conclusions.

RESULTS

The systematic review included a total of 21 studies. The distribution of clinical 7T abdominal imaging studies revealed a predominant focus on the prostate (n = 8), followed by the kidney (n = 6) and the hepatobiliary system (n = 5) . Studies on these organs, and in the pancreas, demonstrated clear advantages at 7T. However, small bowel studies showed no significant improvements compared to traditional MRI at 1.5T. The majority of studies evaluated originated from Germany (n = 10), followed by the Netherlands (n = 5), the United States (n = 5), Austria (n = 2), the United Kingdom (n = 1), and Italy (n = 1).

CONCLUSION

Further increase of abdominal clinical MRI field strength to 7T demonstrated high imaging potential, yet also limitations mainly due to the inhomogeneous radiofrequency (RF) excitation field relative to lower field strengths. Hence, further optimization of dedicated RF coil elements and pulse sequences are expected to better optimize clinical imaging at high magnetic field strength.

Published: January 2024

BACKGROUND

Neoadjuvant chemotherapy (NAC) has become the standard care for advanced adenocarcinoma of esophagogastric junction (AEG), although a part of the patients cannot benefit from NAC. There are no models based on baseline computed tomography (CT) to predict response of Siewert type II or III AEG to NAC with docetaxel, oxaliplatin and S-1 (DOS).

AIM

To develop a CT-based nomogram to predict response of Siewert type II/III AEG to NAC with DOS.

METHODS

One hundred and twenty-eight consecutive patients with confirmed Siewert type II/III AEG underwent CT before and after three cycles of NAC with DOS, and were randomly and consecutively assigned to the training cohort (TC) (n = 94) and the validation cohort (VC) (n = 34). Therapeutic effect was assessed by disease-control rate and progressive disease according to the Response Evaluation Criteria in Solid Tumors (version 1.1) criteria. Possible prognostic factors associated with responses after DOS treatment including Siewert classification, gross tumor volume (GTV), and cT and cN stages were evaluated using pretherapeutic CT data in addition to sex and age. Univariate and multivariate analyses of CT and clinical features in the TC were performed to determine independent factors associated with response to DOS. A nomogram was established based on independent factors to predict the response. The predictive performance of the nomogram was evaluated by Concordance index (C-index), calibration and receiver operating characteristics curve in the TC and VC.

RESULTS

Univariate analysis showed that Siewert type (52/55 vs 29/39, P = 0.005), pretherapeutic cT stage (57/62 vs 24/32, P = 0.028), GTV (47.3 ± 27.4 vs 73.2 ± 54.3, P = 0.040) were significantly associated with response to DOS in the TC. Multivariate analysis of the TC also showed that the pretherapeutic cT stage, GTV and Siewert type were independent predictive factors related to response to DOS (odds ratio = 4.631, 1.027 and 7.639, respectively; all P < 0.05). The nomogram developed with these independent factors showed an excellent performance to predict response to DOS in the TC and VC (C-index: 0.838 and 0.824), with area under the receiver operating characteristic curve of 0.838 and 0.824, respectively. The calibration curves showed that the practical and predicted response to DOS effectively coincided.

CONCLUSION

A novel nomogram developed with pretherapeutic cT stage, GTV and Siewert type predicted the response of Siewert type II/III AEG to NAC with DOS.
Prehistory of Bangladesh in the Light of Recent Discovery

Published: January 2024

Bangladesh has deep historical roots, with a significant concentration of prehistoric evidence discovered primarily at the Lalmai Hill range in Cumilla district and Chaklapunji in Habiganj district. This study focuses on the Lalmai Hill range in Cumilla, which comprises multiple sites that have garnered considerable attention due to their rich prehistoric heritage. While previous investigations focused on the southern part, covering a length of 16.53 km and a width of 1 km to 2.5 km, this study aimed to explore the entire hill range with the objective of uncovering new signs of prehistoric activities and digitally documenting them. Intrusive surface surveys were conducted in an unsystematic manner due to the challenging hilly terrain, and samples were collected without following a predetermined sampling strategy. The findings reveal the discovery of four new sites in the southern region, where sixty-one Stone Age tools were unearthed. The results show that the tool assemblages consist of two major categories with six different varieties based on their typology. Detailed examination of the physical attributes of the tools primarily reveals controlled knapping techniques applied to remove flakes and manufacture the tools. The presence of fossil wood and the absence of fossil wooden tools in the northern and middle sections of the hill range suggest that the southern part offered favorable environmental resources for shelter to prehistoric migrants. Additionally, the exposed fossil woods, which served as suitable raw material, are prominent features of the Dupi Tila formation, dating back to the Plio-Pleistocene epoch. The study underscores the importance of continued investigation and excavation to unravel the intricate signs of prehistoric culture within this archaeological landscape.

The Trends in Taiwanese historical research after the Re-Election of the DPP
Authors:   Institute for Historical Studies at Chung-Ang University, Kim Bong Jun
Published: January 2024

This article aims to elaborate on the current trends and features of Taiwan history research and to provide a direction for Korean academic to understand Taiwanese society and history. In the main, this article will attempt to analyse the current trends and characteristics of Taiwanese history research, with a particular focus on the changes since the DPP's return to power and their impact. In the 2016, Taiwanese presidential election, the DPP won power, and Tsai Ing-wen was re-elected in the 2020 presidential election. There is an ongoing debate on how these political changes affect the study of Taiwanese history, and how Taiwan's identity and inherent capabilities have been historically emphasised in the context of de-Chinaisation.
In addition, the overall trend in Taiwanese history research has been to move away from a focus on colonialism and continental nationalism in the past, and to emphasise the need for Taiwanese to write their own history and to be seen as the agents of Taiwan's history. This shows that the study of Taiwanese history is endeavouring to understand historical agency from different perspectives. The study of population movements and migration to Taiwan since prehistoric times is also being conducted from a variety of perspectives. Recent research trends have been characterised by an exploration of the background and characteristics of Taiwan's population movements in various areas, including geographical and economic causes, as well as political fluctuations, changes in political structures, and changes in identity.
Since 20 century, the study of Taiwan history has reflected a diversity of values and emphasised the recognition that Taiwan is a pluralistic society. In particular, efforts have been made to identify the impact of social phenomena such as migration, economic change, and natural disasters on Taiwanese history, as well as political change and the expansion of power. In addition, recent studies of Taiwanese history have sought to demonstrate that ethnicity, religion, and community are indicators of current social conflicts. These themes are emerging as important aspects of Taiwanese history, which is an indication of the growing interest in studying how they operate as axes of change and conflict within Taiwanese society.

Published: January 2024

La pandemia de COVID-19 condujo, entre otras cosas, a la escasez de alcohol etílico en México, principal componente del gel antibacterial. Esto principalmente se debe al repentino aumento en la demanda, pero también a la limitada producción. Para evitar que se repita este escenario es imprescindible buscar otras fuentes de abastecimiento, siendo la producción de bebidas alcohólicas, artesanal e industrial, la mejor opción. Sin embargo, es importante que la producción de alcohol sea sustentable. Una alternativa al proceso de destilación es la aplicación de energía solar, que resulta en una solución eficiente para satisfacer las necesidades actuales, además de ser amigable con el medio ambiente al no generar emisiones contaminantes y usar un recurso renovable que es gratuito. Muchas regiones del país también pueden beneficiarse de esta tecnología, México tiene bebidas autóctonas y con denominación de origen como el tequila o el mezcal. En el presente artículo se realiza una revisión profunda de la producción científica sobre los prototipos que se han desarrollado para destilar alcohol tanto en el extranjero como en México.

Published: January 2024

A oncogênese é um processo multifatorial que leva a mudanças na homeostase celular e as terapias antineoplásicas têm como consequência efeitos adversos em sítios bucais. Dessa forma, estabelecer o conhecimento a respeito de tais terapias e seus efeitos adversos é de fundamental importância para a odontologia. Assim, esta pesquisa tem como objetivo traçar o perfil epidemiológico de um ano de implantação do Serviço de Odontologia no setor da oncologia do Hospital Universitário de Aracaju (HU/UFS), determinando a prevalência das neoplasias, bem como o perfil sociodemográfico da população assistida e as principais drogas antineoplásicas utilizadas nas terapias. Para isso, foi realizado um estudo observacional de caráter analítico, transversal, que utilizou recursos técnicos da abordagem quantitativa. Foram incluídos prontuários dos pacientes que foram atendidos no setor de oncologia e acompanhados pelo Serviço de Odontologia. A pesquisa foi constituída por três etapas: (1) seleção dos prontuários, (2) coleta de dados e (3) análise e tabulação dos dados. Foi realizado a análise descritiva, sendo apresentada em forma de gráficos e tabelas, tanto em valores absolutos quanto em percentuais. Como resultado, observou-se que o perfil epidemiológico dos pacientes oncológicos atendidos foi, predominantemente, composto por indivíduos adultos, casados, de cor parda, com nível educacional de ensino fundamental e oriundos do interior do estado de Sergipe. Quanto ao tipo da neoplasia, o câncer de mama foi o mais prevalente, sendo o sexo feminino mais frequente nesse tipo de patologia. Já no masculino, houve uma predominância do câncer de pulmão. Em relação aos quimioterápicos, os mais utilizados para tratamento foram o paclitaxel e a ciclofosfamida. No que diz respeito ao número de óbitos, 18 pacientes faleceram no período avaliado. Assim, conhecer o perfil epidemiológico desses pacientes é de suma importância para o planejamento das ações preventivas, diagnósticas e de terapêutica odontológica, assim como das políticas públicas. Além disso, com o aumento crescente do número de casos desta patologia no mundo, o cirurgião-dentista deve estar atualizado e capacitado para realizar o tratamento mais adequado possível.

TIME SERIES WITH MULTIPLE CHANGE POINTS AND CENSORED OBSERVATIONS

This article examines a Bayesian model for a nonstationary time series with an unknown number of change points and censored observations. Each segment is assumed to be an autoregressive process with order one. To estimate the number and locations of change points, we use the reversible jump Markov chain Monte Carlo (RJMCMC) algorithm. The censored problem is solved by imputing the censored values from a multivariate normal distribution based on the observed part. A numerical example shows that the estimates of the number of change points and their localizations have little bias. Additionally, the estimates are robust to the censoring percentage.
