Predictors of First-Time NCLEX-RN Pass Rate in Accelerated Bachelor of Science in Nursing Students
Authors: Mahmoud Khadejah F. , Zhao Jian , Kyung Kim Do , Hui Vivian , Kitutu Julius 
Published: January 2024

Background:
An accelerated Bachelor of Science in Nursing (ABSN) program was introduced in an effort to reduce the nursing shortage in response to the growing health demands. Nursing educators strive to examine factors that promote students' success in passing the National Council Licensure Examination for Registered Nurses (NCLEX-RN) on their first attempt. However, little is known about which factors predict the NCLEX-RN first-time pass rate of ABSN students.

Method:
This descriptive retrospective study examined academic and nonacademic indicators (e.g., age) that can predict ABSN students' NCLEX-RN first-time pass rates between 2008 and 2019.

Results:

A total of 591 ABSN students were included in the study. Both GRE (Graduate Record Examination) verbal reasoning scores (
p
< .001) and cumulative grade point averages (
p
< .001) were significant predictors.

Conclusion:

The findings of this study can help inform ABSN programs in terms of admission criteria and curriculum consideration for including standardized tests to improve ABSN students' NCLEX-RN first-time pass rate.

Published: January 2024

Résumé : Un édifice de culte et son cimetière (fin du vie-milieu du xie siècle) ont été fouillés à Romilly-sur-Andelle, en Normandie, en 2006 et 2007. Plus de 720 tombes ont été mises au jour, constituant un corpus suffisamment conséquent pour mener une réflexion sur l’évolution de l’organisation de l’espace sépulcral et une étude approfondie des données biologiques de la population inhumée, incluant des analyses statistiques pertinentes. Nous présentons la question précise de la présence d’armes dans des sépultures biologiquement féminines ; quatre cas ont été mis en évidence sur ce site dont trois avec une fiabilité de plus de 95 % pour la détermination du sexe. La problématique des femmes armées est replacée dans le contexte des études de genre et des méthodes en archéologie funéraire, en soulignant la fiabilité de nos résultats.
Heat-induced changes in the histomorphometry of human femur bone
Authors: Oghenemavwe Loveday Ese , Orupabo Clinton David , Praise Shaka Ogheneochuko 
Published: January 2024

ABSTRACT

Background:
Skeletal remains are often subjected to unexpected and adverse conditions which can eventually distort evidence. Therefore, understanding the factors that alter skeletal remains is crucial.

Methods:
A total of human femur fragments obtained from the gross anatomy laboratory of the University of Port Harcourt were used. Bone samples were divided into four groups. Group 1 is the control sample comprising bone fragments not exposed to heat, Group 2 had bones exposed to heat at 20°C, Group 3 had bones exposed to heat at 100°C, and Group 4 had bones exposed to heat at 200°C. Ground bone sections were prepared using Modified Frost’s manual method of bone preparation. Morphometric analysis of the micrographs was performed using the ImageJ software.

Results:
Data were analyzed using the SPSS software. The mean values of the Haversian canal area and diameter demonstrated a nonsignificant increase in the bone samples exposed to heat compared to the samples not exposed to heat. The osteon count was slightly higher, but the difference was not statistically significant (P > 0.05).

Conclusion:
The results demonstrated that histomorphometric features of bones are not altered at the temperature of 200°C. This information is useful in forensic investigations.

Authors: Movaniya Pratap N , Desai Nimisha N. , Makwana Tushar R. , Matariya Riddhi G. , Makwana Kalpesh G. , Patel Hirakben B. , Patel Yama N. 
Published: January 2024

Abstract

Introduction:
The clinical application of the diode laser seems to have beneficial effects in surgery. The laser provides precise and rapid tissue dissection, excellent haemostasis and lessens post-operative inflammation. This study was done to assess the clinical effectiveness of diode laser in the management of different varieties of intraoral soft-tissue lesions.

Materials and Methods:
After applying exclusion criteria, a total of 50 samples were selected with benign intraoral soft-tissue lesions treated with a diode laser under local anaesthesia between September 2017 and September 2020. Each patient was followed up on the 3rd, 7th and 15th post-operative days for healing, pain, infection and swelling.

Results:
From all patients, a total of 50 were evaluated in the study; out of all, 60% of patients had no pain on the 2nd follow-up. As per the Landry Index of Healing, 54% of patients had excellent healing. None of the cases had post-operative bleeding, infection was present in 4% at the 1st–2nd follow-up, and in 2% of cases, post-operative swelling was present. The efficacy of diode lasers was tested using the Chi-square test and P < 0.01, which was statistically significant.

Discussion:
Diode laser seems to be superior over conventional treatment modalities as it provides a bloodless dry field and increases patient comfort during surgery. It also lessens the post-operative pain and swelling. Diode laser can safely and effectively be used as a treatment modality for benign soft-tissue lesions, without any complication and without compromising the health and function of patients.

Authors: Vinay C. , Zameer M. M. , Rao Sanjay , D’Cruz Ashley 
Published: January 2024

ABSTRACT

Aims and Objectives:
Complications following posterior sagittal anorectoplasty (PSARP) for ARM are well known. In this article, we present our experience of managing five patients who required major redo surgeries for complications resulting from previous attempts to correct ARM.

Materials and Methods:
We reviewed all patients who underwent major redo surgeries in our hospital for complications from previous repairs for ARM, from June 2013 to June 2019. Data was obtained from hospital records and analysed.

Results:
Five patients whose ages ranged from 5 months to 14 years were included in the study. Four were boys and 1 was a girl. All patients had undergone PSARP in other hospitals. The presentations were retained distal bowel causing urinary retention and constipation (n=1), pulled through proximal urethra and bladder neck presenting as passage of urine from neo-anus (n=1), retained common channel (of cloaca) causing a ‘H’ type configuration (n=1), mispositioned neo-anus (n=1) following a primary PSARP and lastly undivided recto-urethral fistula causing fecaluria (n=1). All of them underwent redo repairs by posterior sagittal approach with documented improvement in their symptoms. Two of them required total bowel management to remain clean.

Conclusion:
All the complications reported here have been described in literature nevertheless, this report will add to the body of experience. Posterior sagittal approach (PSA) has proved to be very successful technique in correcting these complications.

Published: January 2024

ABSTRACT

Background and Aims:
Hirschsprung disease (HSCR) is a congenital disorder of unknown etiology affecting the enteric nervous system (ENS). Since the early gestational development of the ENS is dependent on the prenatal maternal metabolic environment, the objective of this pilot study was to explore the role of specific maternal plasma metabolites in the etiology of HSCR.

Methods:
In this cross-sectional study, postnatal (as a surrogate for prenatal) plasma samples were obtained from mothers of children diagnosed with HSCR (n = 7) and age-matched mothers of normal children (n = 6). The plasma metabolome was analyzed by ultra-high-pressure liquid chromatography and mass spectrometry. Metabolites were identified by mzCloud using Compound Discoverer software. Using an untargeted metabolomics workflow, metabolites with case versus control group differences were identified.

Results:
A total of 268 unique plasma metabolites were identified and annotated in maternal plasma. Of these, 57 were significantly different between case and control groups (P < 0.05, t-test). Using a false discovery rate corrected cutoff of 10% to adjust for multiple comparisons, 19 metabolites were significantly different in HSCR cases, including carnitines, medium-chain fatty acids, and glutamic acid. Pathways affected were for amino acid and lipid metabolism.

Conclusion:
Disordered prenatal metabolic pathways may be involved in the etiopathogenesis of HSCR in the developing fetus. This is the first study to assess maternal plasma metabolomics in HSCR.

Authors: Nirmalan Shajini , Ramaswamy Senthilnathan , Shanmugam Vivek , Natarajan Karpaga Vinayagam 
Published: January 2024

ABSTRACT

Background:
Mesohepatectomy (MH) or central hepatectomy (CH) is a recognized surgical technique for centrally located pediatric liver tumors. This technique of liver resection avoids extended liver resections and thereby helps in the preservation of liver parenchyma. In this article, we aim to analyze our experience and outcome with this technique of liver resection.

Methods:
A retrospective analysis of patients who underwent MH from January 2015 to June 2023 at our institute was performed. The variables analyzed include demographics, preoperative treatment, perioperative management, and postoperative outcome.

Results:
A total of five patients underwent CH. Four patients had hepatoblastoma, and one patient had mesenchymal hamartoma. All four patients with hepatoblastoma received neoadjuvant chemotherapy. All five patients had negative surgical margins, and one of the five developed disease recurrences necessitating resurgery and ultimately died of metastasis. one patient sustained intraoperative major bile duct injuries, and one patient had postoperative Abnormal, well-circumscribed, extra-biliary collection of bile.

Conclusion:
MH with clear margins is feasible in the selected subset of pediatric liver tumors involving segments IV, V, and VIII with outcomes equivalent to extended hepatic resections.

Authors: Verma Ajay , Dhua Anjan Kumar , Kandasamy Devasenathipathy , Gupta Amit , Bhatnagar Veereshwar 
Published: January 2024

ABSTRACT

Aim:
The aim is to study intrahepatic biliary architecture in patients following Kasai’s portoenterostomy for extrahepatic biliary atresia using magnetic resonance cholangiopancreatography (MRCP).

Materials and Methods:
It is a prospective observational study in a cohort of patients who have survived with a complete jaundice-free period for at least 1 year. MRCP was done to look for various intrahepatic architectural changes during their last visit. Findings were correlated with liver functions and growth and development.

Results:
Twenty-one patients were included in the study. The male-to-female sex ratio was 1.6:1, the median age at surgery was 75 days (18–140 days), and the median age at magnetic resonance imaging (MRI) was 4 years (18 months–18 years). More than 2 years of follow-up was in seven patients. Left lobe hypertrophy was observed in six patients, right lobe hypertrophy was in three patients, intrahepatic biliary tract dilatation was in five patients, and altered signal intensity between intrahepatic ducts was seen in five patients. In addition, hypointense foci in the spleen were seen in one patient. Twelve children had normal weight for their age, ten children had the normal height for their age, and gamma-glutamyl transferase was elevated in all children. Only four children had a history of fever and jaundice.

Conclusions:
The patients who survive after successful surgical intervention have near-normal liver gross architecture as on MRI/MRCP. Occasional findings of dilatation and lobar atrophy/hypertrophy are possible, especially in those with a history of cholangitis. The survivors also have acceptable growth parameters and normal liver functions.
Long-term Outcome of Laparoscopic Surgery for Nonpalpable Undescended Testis
Authors: Joshi Nachiket Milind , Shah Rasik Shamji 
Published: January 2024

ABSTRACT

Aims and Objectives:
The aim of this study was to objectively assess the long-term results of laparoscopic orchidopexy in patients who were diagnosed clinically to have nonpalpable undescended testis (UDT).

Materials and Methods:
All operated cases of nonpalpable UDT from January, 2000, to January, 2014, were reviewed. After informed consent, all patients were subjected to a color Doppler ultrasound examination to assess the location of the testis, its size, blood supply, and consistency. The size of the testis, operated and nonoperated, was noted down in volume using the formula of 0.71 × length × breath × height.

Results:
A total of 114 patients could be identified, who had undergone laparoscopy for nonpalpable UDT in the study period. Of these, 44 patients (54 units) underwent a color Doppler study to assess the testes. All the testes were found to lie in the scrotum with preserved blood supply. The volume of the operated unilateral testes (mean = 1.605 cm3) was smaller than the normal nonoperated side (mean = 2.524 cm3). The smaller testicular volume was observed in spite of maintained blood supply to the testes. In cases of bilateral UDT, both the testes were smaller in size (mean = 2.2 cm3), but were comparable to each other. In addition, the ultrasound examination revealed the presence of normal homogenous parenchyma of all the testes similar to the nonoperated side.

Conclusion:
Laparoscopic orchidopexy is a safe and effective option in the treatment of nonpalpable UDT. On a long-term basis, it is possible to achieve scrotal position along with preserved blood flow following laparoscopic orchidopexy in all patients suffering from nonpalpable UDT.
Physiological and Anesthetic Considerations of Safe and Optimal Pneumoperitoneal Pressures for Laparoscopic Surgeries in Children
Authors: Joon Preeti , Mandelia Ankur , Dhiraaj Sanjay , Singh Tapas Kumar , Shamshery Chetna , Mishra Prabhaker 
Published: January 2024

ABSTRACT

Context:
In the era of minimally invasive surgeries, pediatric laparoscopic surgeries are now becoming the standard of care.

Aim:
In this study, we aim to determine the safe and optimal pneumoperitoneal pressures (PPs) for laparoscopic surgery in children aged 1–5 years, along with the technical ease for the surgeon.

Settings and Design:
Prospective, randomized, single-blinded study was conducted at SGPGI Lucknow.

Materials and Methods:
Children aged 1–5 years were randomized into Group I (n = 24): PP = 6–8 mmHg and Group II: (PP) = 9–10 mmHg. Hemodynamic, ventilatory, and blood gas changes were measured before CO2 insufflation (T0), 20 min after insufflation (T1), before desufflation (T2), and 10 min after desufflation (T3). Surgeon’s technical ease of surgery, postoperative pain, the requirement of rescue analgesia, time to resume feeding, and complications were recorded and analyzed.

Statistical Analysis Used:
Paired t-test, Mann–Whitney test, and Wilcoxon signed-rank test were used for nonparametric/parametric data. Chi-square/Fisher’s test was used for nominal data.

Results:
Partial pressure of CO2 (PaCO2) was significantly higher in Group II at T1, T2, and T3, requiring frequent changes in ventilatory settings. Postoperative pain scores were higher in Group II at 1, 6, and 12 h, requiring rescue analgesia. Surgeon’s scores and hemodynamics were similar in both groups.

Conclusions:
Higher PP in Group II caused significant changes in PaCO2, end-tidal CO2, and postoperative pain requiring rescue analgesia, but blood gas changes were clinically insignificant and there were no significant changes in hemodynamic parameters. Since the surgeon’s ease of performing surgery was similar in both groups, we recommend that laparoscopy in children aged 1–5 years can be started with lower PPs of 6–8 mmHg, which can be increased if needed based on the surgeon’s comfort and the patient’s body habitus.
Environmental Impact of Pharmaceuticals: A Comprehensive Review
Authors: Ashiwaju Bankole Ibrahim , Uzougbo Chinedum Gloria , Orikpete Ochuko Felix 
Published: January 2024

Abstract
This comprehensive review seeks to evaluate and synthesize the extensive literature regarding the environmental impact of pharmaceuticals, a growing area of concern within the realm of environmental science. Pharmaceuticals, including human and veterinary medicines, have been detected ubiquitously in the environment due to their widespread use and incomplete removal during wastewater treatment processes. These substances pose potential ecological risks due to their bioactive properties, but the magnitude and implications of these impacts are not yet fully understood. Our review covers the major aspects such as pathways of environmental entry, detection methods, potential impacts on flora and fauna, and potential human health implications of pharmaceutical contamination. We further explored the effectiveness of current wastewater treatment technologies in removing these substances and assess the potential of emerging technologies. The review concludes by discussing policy implications and the necessity for a global coordinated response. By encapsulating the breadth of research in this area, we hope to spur further research and foster greater awareness of the environmental implications of pharmaceutical waste.
Zeta functions and topology of Heisenberg cycles for linear ergodic flows
Authors: Butler Nathaniel , Emerson Heath , Schulz Tyler 
Published: January 2024

Placing a Dirac–Schrödinger operator along the orbit of a flow on a compact manifold

M

defines an

{\mathbb{R}}

-equivariant spectral triple over the algebra of smooth functions on

M

. We study some of the properties of these triples, with special attention to their zeta functions. These zeta functions are defined for

\operatorname{Re}(s)>1

by

\operatorname{Trace}(f_{p}H^{-s})

, where

f_{p}

is the uniformly continuous function on the real line obtained by restricting the continuous or smooth function

f

on

M

to the orbit of a point

p\in M

, and

H = -\frac{\partial^{2}}{\partial x^{2}}+ x^{2}

is the harmonic oscillator. The meromorphic continuation property and pole structure of these zeta functions are related to ergodic time averages in dynamics. In the case of the periodic flow on the circle, one obtains a spectral triple over the smooth irrational torus

A_{\hslash}^{\infty} \subset A_{\hslash}

already studied by Lesch and Moscovici. We strengthen a result of these authors, showing that the zeta function

\operatorname{Trace}(aH^{-s})

extends meromorphically to

\mathbb{C}

for any element

a

of the

C^{*}

-algebra

A_{\hslash}

. Another variant of our construction yields a spectral cycle for

A_{\hslash}\otimes A_{1/\hslash}

and a spectral triple over a suitable subalgebra with the meromorphic continuation property if

\hslash

satisfies a Diophantine condition. The class of this cycle defines a fundamental class in the sense that it determines a KK-duality between

A_{\hslash}

and

A_{1/\hslash}

. We employ the local index theorem of Connes and Moscovici in order to elaborate an index theorem of Connes for certain classes of differential operators on the line and compute the intersection form on K-theory induced by the fundamental class.
Crisis del periodismo de fuentes. Las prácticas del periodismo en España en el accidente de Spanair
Authors: García Santamaría José Vicente 
Published: January 2024

El accidente del avión McDonnell Douglas de la compañía Spanair, que ocurrió el 20 de agosto de 2008 en el aeropuerto de Barajas, y las consecuencias de carácter informativo que de este hecho se han derivado, representan una oportunidad única para abordar el estado actual de ciertas prácticas periodísticas en España. En concreto, en este hecho periodístico extraordinario, adquirió una especial relevancia la utilización de las fuentes informativas en una situación de crisis: una prueba que requiere un mayor esfuerzo para encontrar la mayor cantidad posible de fuentes, primarias y especializadas, que proporcionen, en un corto espacio de tiempo, las necesarias claves informativas e interpretativas a las audiencias de los medios. Del mismo modo, fue también una excelente ocasión para estudiar ciertas prácticas del periodismo de investigación, y de los diferentes condicionantes de la agenda mediática. Y, finalmente, como en toda catástrofe aérea, en la que se pueden llegar a dirimir indemnizaciones millonarias, ha resultado también importante la aplicación de una serie de marcos éticos, plasmados en códigos deontológicos, capaces de salvaguardar la tarea de los periodistas.
Los roles periodísticos y la objetividad en el periodismo político escrito suizo y español
Authors: Berganza Conde Mª Rosa , Oller-Alonso Martín , Meier Katrin 
Published: January 2024

En la presente investigación se analizan las diferentes percepciones que poseen sobre los roles profesionales y sobre la idea de objetividad las y los profesionales de la información política de dos diarios de referencia en España y en Suiza, que están situados en una posición similar dentro del sistema de medios de ambos países. Estos medios se estudian desde la perspectiva de la cultura periodística de las dos naciones medida a partir de las dimensiones empíricas creadas por Hanitzsch (2007). A las reflexiones teóricas y a la creación de un modelo de análisis propio de la cultura periodística se añade el trabajo de campo realizado: 19 entrevistas en profundidad realizadas de forma oral y personal a periodistas políticos pertenecientes al periódico Neue Zürcher Zeitung (NZZ) con sede en Zurich (Suiza) y a la redacción de El Mundo. Se trata de un estudio exploratorio en el cual se ha tratado de construir un modelo de análisis teórico consistente de las culturas periodísticas a partir de la bibliografía existente que se ha aplicado a una muestra de periodistas. Los resultados muestran evidencias de dos culturas periodísticas diferentes, aunque también de algunas similitudes, que afectan a la autopercepción de roles profesionales jugados y a la idea de objetividad informativa de las personas encuestadas.
Polar coded cooperative with Plotkin construction and quasi‐uniform puncturing based on MIMO antennas in half duplex wireless relay network
Authors: Zeng Jiangli , Liu Sanya 
Published: January 2024

AbstractRecently, polar code has attracted the attention of many scholars and has been developed as a code technology in coded‐cooperative communication. We propose a polar code scheme based on Plotkin structure and quasi‐uniform punching (PC‐QUP). Then we apply the PC‐QUP to coded‐cooperative scenario and built to a new coded‐cooperative scheme, which is called PCC‐QUP scheme. The coded‐cooperative scheme based on polar code is studied on the aspects of codeword construction and performance optimization. Further, we apply the proposed schemes to space–time block coding (STBC) to explore the performance of the scheme. Monte Carlo simulation results show that the proposed cooperative PCC‐QUP‐STBC scheme can obtain a lower bit error ratio (BER) than its corresponding noncooperative scheme.
