Authors: Sundram Sonali , Dhiman Neerupma , Malviya Rishabha , Awasthi Rajendra 
Published: August 2023

Introduction:
Polysaccharides are widely used in the biomedical and food industries as
thickening, gelling, emulsifying, hydrating, and suspending agents. Polysaccharides have adequate
viscoelastic properties and flow characteristics. The purpose of this study was to determine various
rheological parameters of Acacia nilotica (Babool) gum.

Methods:
Understanding the influence of temperature on rheological properties is quite important
for polymeric materials to be considered as pharmaceutical excipients. Thus, a polymeric solution
of purified Babool gum was prepared, and the influence of temperature on its rheological behaviour
(viscosity and surface tension) was investigated to develop a better understanding of the structural
organization of the gum. Furthermore, viscosity, surface tension, temperature coefficient, activation
energy, Gibbs free energy, Reynolds number, and entropy of fusion were calculated using the Arrhenius,
Gibbs–Helmholtz, Frenkel–Eyring, and Eotvos equations, respectively.

Results:
The activation energy of the gum was 3.81 ± 0.18 kJ/mol. Changes in entropy and enthalpy
were 0.56 ± 0.23 and 4.27 ± 0.81 kJ/mol, respectively. The calculated amount of entropy of fusion
was found to be 0.014 ± 0.01 kJ mol−1 K−1.

Conclusion:
The study outcomes showed that the viscosity and surface tension increased as the
temperature decreased. The good rheological properties of Babool gum make it a suitable excipient
for its applications in the food and pharmaceutical industries.

Indonesian Women
Authors: Lumbanraja Irwin Lamtota , Aldiansyah Dudy , Halim Binarwan , Lubis Muara Panusunan , Kaban Yostoto Berkat , Rivany Riza 
Published: August 2023

Introduction:
Niche or cesarean scar defect is a complication of a cesarean section that has
long-term implications for both obstetrics and gynecology. The rate of niche is believed to be increasing
with the high number of cesarean sections. This study assesses the risk factors for niche development
after cesarean section.

Methods:
A prospective cohort study was conducted on women who underwent cesarean section at
the Haji Adam Malik General Hospital Medan between August 2020 and August 2022. Niche was assessed
six weeks after cesarean section using transvaginal ultrasonography. The primary outcome was
the presence of a niche. The antepartum, intrapartum and postpartum risk factors were analyzed for
niche development. A logistic regression model was used to assess independent risk factors from the
bivariate analysis.

Results:
There were 280 patients enrolled in this study. The prevalence of niche was 44.3% by using
transvaginal ultrasound. There was no significant relationship between maternal age, gestational age,
parity, nutritional status based on upper arm circumference, hypertension in pregnancy, anemia status,
surgical indications, duration of surgery, volume blood loss, and puerperal infection to niche development
(P > 0.05). The independent risk factors for niche development were Cervical dilatation > 4
cm (P = 0.035; RR = 1.75), locking suture technique (P = 0.015; RR = 13.81), non-closure vesicouterine
folds (P = 0.04; RR = 0.14) and a retroflexed uterus (P = 0.001; RR = 0.039).

Conclusion:
Cervical dilatation > 4 cm, locking suture technique, non-closure vesicouterine folds, and
a retroflexed uterus are risk factors for niche development after CS.
Nonlinear Loads Modelling and Harmonics Analysis: A Review
Authors: Htita Ibrahim , Abdalla Omar H. , El Korfolly M.I. , Elmasry Said 
Published: August 2023

Abstract:
In modern life, the applications of nonlinear loads are increasing, especially electronic
loads, such as computers, monitors, and battery chargers. Moreover, the usage of semiconductors
has increased in modern lighting systems, such as LED lamps and dimmers which are used to control
the lighting level. Nonlinear loads may also be in the form of variable speed drive or arc furnace
loads. Due to the spread of nonlinear loads, large amounts of harmonics are generated. To study the
harmonics of nonlinear loads, it is essential to represent nonlinear loads by their equivalent models
in the simulation programs. This paper presents a comprehensive review of modeling methods of
nonlinear loads, including time domain methods, frequency domain methods, and state space methods.
Equivalent circuits are presented for different types of nonlinear loads, including static loads,
dynamic loads and arc furnace loads. The paper also presents the harmonic analysis performed by
the Fourier transform of different types of nonlinear loads, including harmonic percentage and its
angle. This paper is considered as a comprehensive reference for researchers and engineers to model
nonlinear loads and is useful in power system planning for connecting nonlinear loads where mixing
nonlinear loads of similar harmonic profiles causes worse situations. Moreover, knowing the nonlinear
load profile will help in the suitable mixing of linear loads to achieve lower harmonics levels.
Exploring the Perspectives and Experiences of Older Adults With Asthma and Chronic Obstructive Pulmonary Disease Toward Mobile Health: Qualitative Study
Authors: Kouri Andrew , Gupta Samir , Straus Sharon E , Sale Joanna E M 
Published: August 2023

Background
The use of mobile health (mHealth) in asthma and chronic obstructive pulmonary disease (COPD) is growing, and as the population ages, a greater number of older adults stand to benefit from mHealth-enhanced airway disease care. Though older adults are a heterogeneous population of health technology users, older age represents a potential barrier to health technology adoption, and there is currently a lack of knowledge on how older age influences mHealth use in asthma and COPD.

Objective
In this qualitative study, we sought to explore the experiences and perspectives of adults who were aged 65 years and older with asthma and COPD toward mHealth use.

Methods
Semistructured individual interviews were conducted with adults who were aged 65 years and older with asthma or COPD and owned a smartphone. Applying phenomenological methodology, we analyzed interview transcripts in order to develop themes and propose an essential experience of mHealth use among older adults with airway disease. We then summarized our qualitative findings and proposed strategies to leverage our results in order to guide future research and implementation efforts targeting older adults’ use of airway mHealth.

Results
Twenty participants (mean age 79.8, SD 4.4 years) were interviewed. Participants described a central tension between (1) the perception that mHealth could help maintain independence throughout aging and (2) an apprehension toward the ways in which mHealth could negatively affect established health care experiences. Several elements of these 2 themes are absent from previous research focusing on younger adults with asthma and COPD. The individual elements of these 2 themes informed potential strategies to optimize future older adults’ use of asthma and COPD mHealth tools.

Conclusions
Focusing on the perspectives and experiences of older adults with asthma and COPD in their use of mHealth identified novel understandings of health technology use in this important demographic in need of greater care. These lessons were translated into potential strategies that will need to be objectively evaluated in future airway mHealth research, development, and implementation efforts.
Assessing the Utility of ChatGPT Throughout the Entire Clinical Workflow: Development and Usability Study
Authors: Rao Arya , Pang Michael , Kim John , Kamineni Meghana , Lie Winston , Prasad Anoop K , Landman Adam , Dreyer Keith , Succi Marc D 
Published: August 2023

Background
Large language model (LLM)–based artificial intelligence chatbots direct the power of large training data sets toward successive, related tasks as opposed to single-ask tasks, for which artificial intelligence already achieves impressive performance. The capacity of LLMs to assist in the full scope of iterative clinical reasoning via successive prompting, in effect acting as artificial physicians, has not yet been evaluated.

Objective
This study aimed to evaluate ChatGPT’s capacity for ongoing clinical decision support via its performance on standardized clinical vignettes.

Methods
We inputted all 36 published clinical vignettes from the Merck Sharpe & Dohme (MSD) Clinical Manual into ChatGPT and compared its accuracy on differential diagnoses, diagnostic testing, final diagnosis, and management based on patient age, gender, and case acuity. Accuracy was measured by the proportion of correct responses to the questions posed within the clinical vignettes tested, as calculated by human scorers. We further conducted linear regression to assess the contributing factors toward ChatGPT’s performance on clinical tasks.

Results
ChatGPT achieved an overall accuracy of 71.7% (95% CI 69.3%-74.1%) across all 36 clinical vignettes. The LLM demonstrated the highest performance in making a final diagnosis with an accuracy of 76.9% (95% CI 67.8%-86.1%) and the lowest performance in generating an initial differential diagnosis with an accuracy of 60.3% (95% CI 54.2%-66.6%). Compared to answering questions about general medical knowledge, ChatGPT demonstrated inferior performance on differential diagnosis (β=–15.8%; P<.001) and clinical management (β=–7.4%; P=.02) question types.

Conclusions
ChatGPT achieves impressive accuracy in clinical decision-making, with increasing strength as it gains more clinical information at its disposal. In particular, ChatGPT demonstrates the greatest accuracy in tasks of final diagnosis as compared to initial diagnosis. Limitations include possible model hallucinations and the unclear composition of ChatGPT’s training data set.

ABSTRAK

Hipertensi merupakan penyebab utama penyakit kardiovaskular dengan angka kematian tertinggi di dunia. Berbagai upaya dapat dilakukan untuk menurunkan peningkatan tekanan darah dengan mengkonsumsi obat antihipertensi, melakukan olahraga dan aktivitas fisik, mengelola stres serta melakukan pembatasan terhadap asupan makanan tinggi garam dan lemak. Permasalahan utama dari sulitnya melakukan kontrol terhadap tingginya tekanan darah adalah lemahnya kepatuhan terhadap konsumsi obat antihipertensi dan sulitnya mengatur pola makan rendah garam dan kolesterol. Selain itu, penggunaan obat jangka panjang dapat memunculkan kecemasan terhadap efek samping. Alternatif pemanfaatan tanaman herbal Bunga Telang (Clitoria ternatea) dapat menjadi pilihan yang lebih baik dalam penanganan hipertensi. Metode yang digunakan dalam penelitian ini adalah literature review dengan melakukan penelusuran artikel dari Google Scholar, Sciencedirect, dan Pubmed yang terbit pada tahun 2012-2022. Berdasarkan hasil telaah jurnal didapatkan 4 artikel sesuai yang menunjukkan adanya efek positif dari bunga telang dalam menurunkan kadar tekanan darah pada studi yang dilakukan.

Published: August 2023

El presente trabajo se inscribe dentro de las prácticas curriculares desarrolladas en el marco del Taller de Estrategias de Comunicación Sonora y Radial, Cátedra 1, de la Facultad de Periodismo y Comunicación Social, de la Universidad Nacional de La Plata. Se trata del ciclo de Podcast “30 años es mucho” producido por estudiantes a 30 años de la desaparición de Miguel Bru, en la Comisaría 9° de La Plata.
Miguel Bru era estudiante de la Facultad de Periodismo y Comunicación Social de la Universidad Nacional de La Plata. Fue secuestrado, torturado hasta la muerte, y desaparecido el 17 de agosto de 1993, en la Comisaría Novena de La Plata.
Fue el primer desaparecido en democracia. La causa para encontrar a Miguel se inició en 1994. Cinco años después, y a pesar del argumento “si no hay cuerpo, no hay delito”, se logró la condena por homicidio en un caso de desaparición, en lo que es un fallo inédito.
Hoy, a 30 años, la bandera ¿Dónde está Miguel? es no sólo una pregunta, sino el doloroso reclamo en una lucha que continúa.
