Authors: Moodie Douglas R. 
Published: July 2024

<p style="text-align:justify"><span style="font-size:9.0pt"><span style="color:black">Certain demographics of students may prefer certain modalities, and certain demographics may achieve higher mean grades in some teaching modalities than others. This study used student-section data from five years of all the undergraduate courses at Kennesaw State University (KSU) from 2015 to 2019. This data set with individual student course outcomes included full student demographics and course types, including previous university grade point average (GPA), sex, age, ethnicity, course department, modality, etc. The study only used data from those instructors who taught hybrid sections, as well as in-person and online sections, to avoid the effect of instructor bias. Previous research found that instructors who taught hybrid sections gave higher grades for their online and F2F sections compared to those instructors who had not taught hybrid sections. The results showed that that hybrid-teaching instructors gave higher mean course grades for their hybrid sections than their online or F2F sections and higher mean course grades than non-hybrid teaching instructors in all modalities. This effect held for all demographics. </span></span></p>

Published: July 2024

Ultra-high-quality-factor (Q) resonators are a critical component for visible to near-infrared (NIR) applications, including quantum sensing and computation, atomic timekeeping and navigation, precision metrology, microwave photonics, and fiber optic sensing and communications. Implementing such resonators in an ultra-low-loss CMOS foundry compatible photonic integration platform can enable the transitioning of critical components from the lab- to the chip-scale, such as ultra-low-linewidth lasers, optical reference cavities, scanning spectroscopy, and precision filtering. The optimal operation of these resonators must preserve the ultra-low losses and simultaneously support the desired variations in coupling over a wide range of visible and NIR wavelengths as well as provide tolerance to fabrication imperfections. We report a significant advancement in high-performance integrated resonators based on a two-point-coupling design that achieves critical coupling simultaneously at multiple wavelengths across wide wavebands and tuning of the coupling condition at any wavelength, from under-, through critically, to over-coupled. We demonstrate critical coupling at 698 nm and 780 nm in one visible-wavelength resonator and critical coupling over a wavelength range from 1550 nm to 1630 nm in a 340-million intrinsic Q 10-meter-coil waveguide resonator. Using the 340-million intrinsic Q coil resonator, we demonstrate laser stabilization that achieves six orders of magnitude reduction in the semiconductor laser frequency noise. We also report that this design can be used as a characterization technique to measure the intrinsic waveguide losses from 1300 nm to 1650 nm, resolving hydrogen-related absorption peaks at 1380 nm and 1520 nm in the resonator, giving insight to further reduce waveguide loss. The CMOS foundry compatibility of this resonator design will provide a path towards scalable system-on-chip integration for high-performance precision experiments and applications, improving reliability, and reducing size and cost.

Aim
This preliminary study investigated the differences in event-related potential and reaction time under two groups (athletes vs. non-athletes).

Material and methods
The P300 was analyzed for Fz, Cz, and Pz electrodes in thirty-one healthy volunteers divided into two groups (volleyball athletes and non-athletes). In addition, the participants performed a saccadic eye movement task to measure reaction time.

Results
The EEG analysis showed that the athletes, in comparison to the no-athletes, have differences in the P300 in the frontal area (p = 0.021). In relation to reaction time, the results show lower reaction time for athletes (p = 0.001).

Conclusions
The volleyball athletes may present a greater allocation of attention during the execution of the inhibition task, since they have a lower reaction time for responses when compared to non-athletes.

Published: July 2024

Background
Currently, there are few treatment-predictive and prognostic biomarkers in triple-negative breast cancer (TNBC). Caveolin-1 (CAV1) is linked to chemoresistance and several important processes involved in tumor progression and metastasis, such as epithelial-mesenchymal transition (EMT). Herein, we report that high CAV1 gene expression is an independent factor of poor prognosis in TNBC.

Methods
CAV1 gene expression was compared across different molecular features (e.g., PAM50 subtypes). CAV1 expression was assessed in relation to clinical outcomes using Cox regression adjusted for clinicopathological predictors. Differential gene expression and gene set enrichment analyses were applied to compare high- and low-expressing CAV1 tumors. Tumor microenvironment composition of high- and low-expressing CAV1 tumors was estimated using ECOTYPER. Tumor tissue microarrays were used to evaluate CAV1 protein levels in stromal and malignant cells.

Results
In the SCAN-B (n = 525) and GSE31519 (n = 327) cohorts, patients with CAV1-high tumors had an increased incidence of early recurrence adjusted HR 1.78 (95% CI 1.12–2.81) and 2.20 (95% CI 1.39–3.47), respectively. In further analysis, high CAV1 gene expression was associated with a molecular profile indicating altered metabolism, neovascularization, chemoresistance, EMT, suppressed immune response, and active tumor microenvironment. Protein levels of CAV1 in malignant and stromal cells were not correlated with CAV1 gene expression.

Conclusion
CAV1 gene expression in TNBC is a biomarker that merits further investigation in clinical trials and as a therapeutic target.

Published: July 2024

Background
Friedman’s standards, developed almost 50 years ago, may no longer align with the needs of today’s obstetric population and current pregnancy management practices. This study aims to analyze contemporary labor patterns and estimate labor duration in China, focusing on first-stage labor data from Chinese parturients with a spontaneous onset of labor.

Methods
This retrospective observational study utilized data from electronic medical records of a tertiary hospital in Changsha, Hunan. Out of a total of 2,689 parturients, exclusions were made for multiple gestations, preterm, post-term, or stillbirth, cesarean delivery, non-vertex presentation, and neonatal intensive care unit admission. Average labor curves were constructed by parity using repeated-measure analysis, and labor duration was estimated through interval-censored regression, stratified by cervical dilation at admission. We performed an analysis to assess the impact of oxytocin augmentation and amniotomy on labor progression and conducted a sensitivity analysis using women with complicated outcomes.

Results
Nulliparous women take over 180 minutes for cervical dilation from 3 to 4 cm, and the duration from 5 to 6 cm exceeds 145 minutes. Multiparous women experience shorter labor durations than nulliparous. Labor acceleration is observed after 5 cm in nulliparous, but no distinct inflection point is evident in the average labor curve. In the second stage of labor, the 95th percentile for nulliparous, with and without epidural analgesia, is 142 minutes and 127 minutes, respectively.

Conclusions
These findings provide valuable insights for the reassessment of labor and delivery processes in contemporary obstetric populations, including current Chinese obstetric practice.
Antihypertensive utilization patterns among pregnant persons with pre-existing hypertension in the US: A population-based study

Published: July 2024

Background
Hypertension among persons with childbearing potential is on the rise. Maintaining proper blood pressure during pregnancy is vital to prevent maternal and neonatal complications. Yet, limited evidence on the risk-benefit of various antihypertensives presents challenges for informed decision-making during this critical period. This study aimed to examine the utilization patterns of different classes of antihypertensives among persons with pre-existing hypertension before, during, and after pregnancy.

Methods
We used MarketScan® Commercial Database 2011−2020 to analyze antihypertensive utilization among pregnant persons aged 12 to 55 identified via a validated algorithm. Pre-existing hypertension was defined as ≥1 inpatient or ≥2 outpatient encounters for hypertension within the 180 days preceding the LMP. Antihypertensive utilization was described during target periods: 0–3 months (0-3M) before pregnancy, 1st/2nd/3rd trimester (T1/2/3), 0-3M, and 4-6M after pregnancy.

Results
We identified 1,950,292 pregnancies, of which 20,576 (12,978 live and 7,598 non-live) had pre-existing hypertension. Both groups had similar antihypertensive use (80.1% and 81.0%, respectively) during the 6 months before pregnancy (baseline). For live-birth pregnancies, 13.9% of baseline users discontinued treatment during pregnancy, while 28.9% of non-users initiated antihypertensives during pregnancy, and 17.2% started postpartum. Before pregnancy, the predominant antihypertensives included thiazide diuretics (21.9%), combined α- and β-blockers (18.4%), and dihydropyridines (16.2%). During pregnancy, thiazide diuretics, cardioselective β-blockers, and ACE inhibitors declined (T3: 3.0%, 4.2%, and 0.8%). Dihydropyridine use was steady during pregnancy, but preference shifted from amlodipine to nifedipine in T3 (2.2.% vs.10.8%). Central α2‐agonists increased during pregnancy (up to 15.2% in T3) compared to both pre- (9.8%) and post-pregnancy (5.7%). ARBs mirrored ACE inhibitors, with less than 1% utilization in later trimesters. Combination agents dropped from 10.8% pre-pregnancy to 0.8% in T3, then rebounded to 7.3% post-pregnancy.

Conclusion
Research is warranted to evaluate the choice of antihypertensives and optimal timing to switch to safer alternatives, considering maternal and fetal outcomes.
Kapraunia silviae (Rhodomelaceae, Rhodophyta), a new species from the South Atlantic Ocean
Authors: Brito Jhullyrson O.F. de , Cassano Valéria 
Published: July 2024

Abstract

Kapraunia is a genus recently segregated from Polysiphonia sensu lato, with only four species so far known. However, no species have been found on the South Atlantic coast. Recent collections in southwestern Brazil revealed specimens morphologically similar to Kapraunia spp. To investigate the identity of these specimens, we carried out a morphological and molecular study based on COI-5P and rbcL sequences. Phylogenetic analysis placed our samples within the genus Kapraunia as a new species with full support, described here as Kapraunia silviae sp. nov. K. silviae is recognizable by a combination of characters such as attachment by a basal disc and a prostrate system, branches developing laterally to the trichoblasts, 5–6 pericentral cells, rarely 4. The species differs from K. pentamera by the attachment form, segment proportions and tetrasporangial dimensions, and from K. schneideri by the number of pericentral cells, branch development and tetrasporangial arrangement. Re-examination of herbarium samples from Brazil in older collections also revealed misidentifications of K. silviae as “Carradoriella denudata”. This new species seems to be restricted to the Brazilian coast, being found only on the northern coast of São Paulo state. Our results reinforce the need for revision of Polysiphonia s.l. species on the Brazilian coast.

Published: July 2024

Abstract

Objectives
GH-releasing peptide-2 (GHRP2) can be used for provocative growth hormone testing (GHT). Since it acts as a powerful stimulus for GH secretion, cut-off peak GH level in GHRP2 loading test (GHRP2T) is higher than in other GHT. Nevertheless, data on response at adolescents are limited. This report aimed to investigate peak GH levels in GHRP2T in adolescents.

Methods
Clinical data of adolescents after onset of puberty who underwent GHRP2T at our institution from May 2010 to March 2023 were collected retrospectively. Subjects were classified into three groups according to underlying diseases.

Results
A total of 23 patients were included: 12 in organic or genetic GHD (o/gGHD) group, three in idiopathic GHD (iGHD) group, and eight in short stature (SS) group. The median GH peak levels were 3.4 ng/mL in o/gGHD group, 88.9 ng/mL in iGHD group, and 90.1 ng/mL in SS group, indicating a robust response of GH peak levels in iGHD and SS groups. Two patients exceeded the cut-off for GHRP2T but below for other GHT, indicating the current cut-off for GHRP2T may miss some GHD patients.

Conclusions
The GH response to GHRP2T in adolescents except the o/gGHD group may be robustly responsive. For the correct diagnosis of GHD, the cut-off peak GH levels in GHRP2T in adolescents may require revisiting.
The most common graphicons in Mexican Spanish speaking WhatsApp communities composed of school parents
Authors: Flores-Salgado Elizabeth 
Published: July 2024

Abstract
The present study examined the pragmatic functions of graphicons used in six different WhatsApp communities created by and for school parents, written in Mexican Spanish, which had the purpose of sharing information relating to daily classroom concerns. A total of 4,824 WhatsApp messages written by these 143 school parents were analyzed using the taxonomy proposed by Herring and Dainas (2017, Nice picture comment! Graphicons in Facebook comment threads. In: Proceedings of the Fifthieth Hawaii International Conference on System Sciences. IEEE Press, pp. 2185–2194. http://hdl.handle.net/10125/41419). The findings revealed that emoji were the most common graphical device used and they were always visually connected to the verbal content of the speech acts they accompanied. Another result showed that photos were the second most preferred multimodal. These photos were impersonal and as well as emoji, they fulfilled requested tasks as this was a task-oriented group. The findings further suggested that the low frequency of the occurrence of stickers, videos, and GIFS was probably due to the particularities of this community of practice. Thus, the use of emoji and graphicons were constrained by the requested tasks of these communities.

Implications of Hamka’s thoughts in tafsir al-Azhar on the standpoint of Islamic social organizations in preventing authoritarianism in Indonesia
Authors: Shomad Bukhori Abdul , Mujahidin Anwar , Rofiq Ahmad Choirul 
Published: July 2024

Indonesian Islamic social organizations not only function as religious organizations but they serve as interest groups as well. Islamic social organizations are often faced with a dilemma of engaging in practical political matters or otherwise. This study analyzes thoughts and practices relating to the relationship between Islamic social organizations and the state. Study data were mined from Hamka’s thoughts in his seminal work Tafsir al-Azhar and historical documents of Muhammadiyah and the Indonesian Ulema Council (Majelis Ulama Indonesia – MUI) during the early period of the New Order, i.e., 1970-1980. The research questions posed in this study refer to how did Hamka interpret Qur’anic verses containing messages regarding the relationship between society and state and what are their implications on the practices of Indonesian Islamic social organizations in their relational dynamics with the state. Study results indicate that Hamka’s thoughts in Tafsir al-Azhar consider syura (deliberation) as a determinant in the relationship between society and state, and distinction between state and religious authority. The implications that Hamka’s thoughts had on the standpoint of Muhammadiyah as an Islamic social organization was its ability to separate itself from its political party affiliation. Muhammadiyah until 1960s was a special member of the Masyumi party. Following its separation with the Masyumi party, Muhammadiyah became an independent non-government civil institution that is critical of the state. As a civil institution, Muhammadiyah succeeded in playing its role as a civil society organization (CSO) and keeping the political regime to develop into an authoritarian and repressive state.
