Transcriptome analysis suggests broad jejunal alterations in Linghu’s obesity-diarrhea syndrome: A pilot study
Authors: Niu Xiao-Tong , Wang Xiang-Yao , Wang Yan , Han Ke , Ru Nan , Xiang Jing-Yuan , Linghu En-Qiang 
Published: June 2024

BACKGROUND
Obesity is associated with a significantly increased risk for chronic diarrhea, which has been proposed as Linghu’s obesity-diarrhea syndrome (ODS); however, its molecular mechanisms are largely unknown.
AIM
To reveal the transcriptomic changes in the jejunum involved in ODS.
METHODS
In a cohort of 6 ODS patients (JOD group), 6 obese people without diarrhea (JO group), and 6 healthy controls (JC group), high-throughput sequencing and bioinformatics analyses were performed to identify jejunal mucosal mRNA expression alterations and dysfunctional biological processes. In another cohort of 16 ODS patients (SOD group), 16 obese people without diarrhea (SO group), and 16 healthy controls (SC group), serum diamine oxidase (DAO) and D-lactate (D-LA) concentrations were detected to assess changes in intestinal barrier function.
RESULTS
The gene expression profiles of jejunal mucosa in the JO and JC groups were similar, with only 1 differentially expressed gene (DEG). The gene expression profile of the JOD group was significantly changed, with 411 DEGs compared with the JO group and 211 DEGs compared with the JC group, 129 of which overlapped. The enrichment analysis of these DEGs showed that the biological processes such as digestion, absorption, and transport of nutrients (especially lipids) tended to be up-regulated in the JOD group, while the biological processes such as rRNA processing, mitochondrial translation, antimicrobial humoral response, DNA replication, and DNA repair tended to be down-regulated in the JOD group. Eight DEGs (CDT1 , NHP2 , EXOSC5 , EPN3 , NME1 , REG3A , PLA2G2A , and PRSS2 ) may play a key regulatory role in the pathological process of ODS, and their expression levels were significantly decreased in ODS patients (P < 0.001). In the second cohort, compared with healthy controls, the levels of serum intestinal barrier function markers (DAO and D-LA) were significantly increased in all obese individuals (P < 0.01), but were higher in the SOD group than in the SO group (P < 0.001).
CONCLUSION
Compared with healthy controls and obese individuals without diarrhea, patients with Linghu’s ODS had extensive transcriptomic changes in the jejunal mucosa, likely affecting intestinal barrier function and thus contributing to the obesity and chronic diarrhea phenotypes.
Does sleep benefit source memory? Investigating 12-h retention intervals with a multinomial modeling approach
Authors: Berres Sabrina , Erdfelder Edgar , Kuhlmann Beatrice G. 
Published: June 2024

AbstractFor retention intervals of up to 12 h, the active systems consolidation hypothesis predicts that sleep compared to wakefulness strengthens the context binding of memories previously established during encoding. Sleep should thus improve source memory. By comparing retention intervals filled with natural night sleep versus daytime wakefulness, we tested this prediction in two online source-monitoring experiments using intentionally learned pictures as items and incidentally learned screen positions and frame colors as source dimensions. In Experiment 1, we examined source memory by varying the spatial position of pictures on the computer screen. Multinomial modeling analyses revealed a significant sleep benefit in source memory. In Experiment 2, we manipulated both the spatial position and the frame color of pictures orthogonally to investigate source memory for two different source dimensions at the same time, also allowing exploration of bound memory for both source dimensions. The sleep benefit on spatial source memory replicated. In contrast, no source memory sleep benefit was observed for either frame color or bound memory of both source dimensions, probably as a consequence of a floor effect in incidental encoding of color associations. In sum, the results of both experiments show that sleep within a 12-h retention interval improves source memory for spatial positions, supporting the prediction of the active systems consolidation hypothesis. However, additional research is required to clarify the impact of sleep on source memory for other context features and bound memories of multiple source dimensions.

Authors: Wedanta Mahadewi I Gusti Agung , Purwa Sunu Arya Baruna , Adisastra Suryantha 
Published: June 2024

Thyrotoxicosis is a clinical condition associated with excessive thyroid hormone levels. Symptoms can range from asymptomatic to life-threatening due to thyroid storm. Thyrotoxicosis in hydatidiform moles is a rare condition but has a high mortality rate, so etiological studies are still needed for optimal management. Case Report: Patient Mrs. T, 25 years old Hindu, Balinese, 12 weeks pregnant (Gravida 1 Para 0 abortion 0), came to the obstetrics ER on September 24, 2023 with complaints of discharge from the birth canal since the morning, nausea (+), often shaking, easily tired and often sweaty. physical examination obtained blood pressure 100/60mmHg, pulse 78x/min, respiratory rate 20x/min, axillary temperature 36.80C oxygen saturation 99%. From obstetric examination, fundus uteri height ½ center, vaginal toucher vulva vagina within normal limits, portiono (-) fluxus (+), laboratory examination obtained HCG 387,392.8 mIU/m, FT4 31.05 pmol/L (N: 9-22), TSH <0.01 uIU/mL (N: 0.4-4.2) ultrasound results describe honey comb appearance and histopathology results describe partial mola. Evacuation by curettage was performed, resulting in reduced serum ?-hCG levels and reduced thyroid hormone levels. Discussion: The patient was diagnosed with partial hydatidiform mole and thyrotoxicosis. Hydatidiform moles can cause thyrotoxicosis. This condition is caused by the structure of ?- hCG which resembles TSH so that it can activate TSH receptors. After evacuation of hydatidiform moles, normal TSH and FT4 levels will be obtained. Conclusion: The female patient with thyrotoxicosis due to hydatidiform moles had the moles evacuated, resulting in normal thyroid hormone levels.

Abstract
The distribution of stellar obliquities provides critical insight into the formation and evolution pathways of exoplanets. In the past decade, it was found that hot stars hosting hot Jupiters are more likely to have high obliquities than cool stars, but it is not clear whether this trend exists only for hot Jupiters or holds for other types of planets. In this work, we extend the study of the obliquities of hot (6250–7000 K) stars with transiting super-Earth-sized and sub-Neptune-sized planets. We constrain the obliquity distribution based on measurements of the stars’ projected rotation velocities. Our sample consists of 170 TESS and Kepler planet-hosting stars and 180 control stars chosen to have indistinguishable spectroscopic characteristics. In our analysis, we find evidence suggesting that the planet hosts have a systematically higher

compared to the control sample. This result implies that the planet hosts tend to have lower obliquities. However, the observed difference in

〈

is not significant enough to confirm spin–orbit alignment as it is 3.8σ away from perfect alignment. We also find evidence that within the planet-hosting stars there is a trend of higher obliquity (lower

) for the hotter stars (T

) than cooler planet-hosting stars, indicating that high obliquities are not exclusive to hot Jupiters and instead are more broadly tied to hot stars.
Seamful Sutures: Gender Exploration and Identity Expression Using Augmented Reality Facial Filters
Authors: Marghitu Stefania , O’Meara Jennifer 
Published: June 2024

This paper examines gender performativity and identity as expressed through facial beauty filters, as mainstreamed on dominant social media platforms Instagram and TikTok. It provides a framework for the widespread use of augmented reality (AR) filters on social media, which we theorize in relation to feminist and queer methodologies, as well as screen theories of “seamfulness” and “mechanic sutures.” With reference to studies of selfie culture, social media, and digital beauty norms, as well as illustrative examples of the facial filters’ design and use, we consider idealized forms of cisgender feminine appearance as well as queer and nonbinary forms of identity. Our case studies range from analysis of the viral Bold Glamour makeup filter to custom filters made by musicians Björk and Ariana Grande. We highlight potential benefits to these filters, including their ability to playfully shield the user’s face from a critical gaze, to reduce costs associated with presenting idealized forms of beauty, and to offer nonbinary users liminal media spaces through which to explore self-image. Overall, the paper provides a theoretical model for understanding the widespread use of facial filters on social media and their impact for intersectional gendered dynamics. It also provides important historical and conceptual context to dominant critical discourse that foregrounds their negative impact on women over other potential benefits.
Evaluation of posterior femoral condyle depth as an anatomical risk factor for anterior cruciate ligament injury among Egyptian population
Authors: Sherif Eltregy 
Published: June 2024

Background
The purpose of this study was to investigate the influence of posterior femoral condylar depth on risk of sustaining anterior cruciate ligament (ACL) injury among the Egyptian population.

Patients and methods
A total of 400 patients (200 ACL ruptured and 200 ACL intact) were included. Morphometric parameters were measured on knee lateral radiographs, with overlapping of the femoral condyles. Radiographic measurements included the posterior femoral condyle offset (PCO) and ratio.

Results
The PCO and ratio showed significant differences between both groups. The receiver-operating characteristic curve revealed that the PCO cutoff value of more than 67.8 was associated with increased ACL injury with 76% sensitivity and 74% specificity.

Conclusions
The data from our study demonstrated that an increase in posterior femoral condyle ratio was associated with an increased prevalence of ACL injuries in Egyptian population. However, further research is needed to determine the distal femur morphology in the Egyptian population and its effect on the risk of primary and secondary ACL injury.

Percutaneous osteotomy and simple monolateral frame for treatment of developmental coxa vara
Authors: Ramy Ahmed , Hashem Mohammed H. 
Published: June 2024

Objectives
Although subtrochanteric valgus osteotomy is considered the standard surgical management of developmental coxa vara, the method of fixation of the osteotomy is still a debate. This study aimed to assess the results and to evaluate the efficacy of percutaneous osteotomy and fixation by monolateral external fixator for the treatment of developmental coxa vara.

Patients and methods
Between December 2017 and February 2020, we conducted a prospective study that involved 10 cases (four females and six males). The patients’ ages at the time of presentation ranged from 4.5 to 12 years with a mean of 6.7 years. All patients underwent percutaneous osteotomy and fixation by a monolateral external fixator. The mean follow-up period was 21 months (range, 14–28 months). Radiological evaluation depended on epiphyseal Hilgenreiner angle and neck-shaft angle, clinical evaluation depended on the IOWA score (it is the hip score of University of IOWA in USA).

Results
There was a significant improvement of the mean values of epiphyseal Hilgenreiner angle (80.6–29.1°), neck-shaft angle (86.9–129°), and IWOA score (58.4–92.2), there was one case of postoperative abductor tightening treated by abductor release and two cases of superficial pin-tract discharge treated by oral antibiotics and all three cases had excellent IOWA score at the last follow-up.

Conclusion
Using percutaneous valgus osteotomy and fixation by monolateral frame provides a reliable, less-invasive, low-cost option for the treatment of developmental coxa vara.
Percutaneous double osteotomy of the first metatarsus for correction of severe hallux valgus deformity
Authors: Ewais Waleed M. 
Published: June 2024

Background
The goal of operative treatment of severe hallux valgus (HV) is to offer relief of pain, correction of forefoot deformity, and a biomechanically functional foot. However, the authors are constantly exploring ways of moving from open surgery to minimally invasive techniques, replacing large incisions with small ‘ports’ through which the surgeon works. Percutaneous less-invasive techniques have been successfully used for mild to moderate HV deformities; however, controversy exists for their use in cases with more severe involvement.

Aim
The aim of this prospective study was to assess the clinical and radiological outcomes of a percutaneous minimally invasive technique for the management of severe HV deformity.

Patients and methods
Between July 2013 and June 2015, 36 feet in 24 active patients, comprising 18 female and six male patients, where 12 patients had bilateral involvement, met the selection criteria for symptomatic severe HV deformity and treated by a minimally invasive double metatarsal osteotomy technique. The procedure implied simple transverse-osteotomy, with lateral translation, of the first metatarsus both proximally and distally combined with selective distal soft-tissue dissection. Average patients’ age was 39.8 years. Clinically, the American Orthopedic Foot and Ankle Society score and the subjective patient satisfaction were evaluated. Radiologically, HV angle, distal metatarsal articular angle, intermetatarsal angle, and joint congruity were measured preoperatively, postoperatively, and at the end of the follow-up period. All data were statistically analyzed.

Results
The mean follow-up period was 21.3 months (range: 18–24 months). Union was achieved in all osteotomies in a mean of 6.67±0.45 weeks. Each radiological and clinical parameter showed a statistically significant improvement (P<0.001), with a negligible first-ray shortening (P=0.547) and a few complications. At the end of follow-up period, no patient was dissatisfied.

Conclusions
Percutaneous double first metatarsal osteotomy technique with selective distal soft-tissue dissection provides a simple, adequate reproducible procedure, and effective alternative for treatment of severe HV deformity in a minimally invasive procedure.
Arthroscopic ankle arthrodesis for chronic posttraumatic end-stage ankle arthritis in middle-age adults
Authors: Montaser Mohamed G. 
Published: June 2024

Background
The aim of this prospective study was to assess the clinical results of arthroscopic ankle arthrodesis for end-stage ankle arthritis in middle-aged active adults, as an alternative to open ankle arthrodesis based on the hypothesis that arthroscopic technique yields similar or better results but with less complications and shorter hospital stay.

Patients and methods
Between May 2012 and October 2014, this prospective case study was conducted on 19 middle-aged active patients who met the criteria and were followed for at least 2 years. Clinical grading was done at 6 months postoperatively, and final subjective clinical and radiologic assessment was done at least 2 years postoperatively, dividing the results into four groups (excellent, good, fair, and poor).

Results
After an average of 27.5 months of follow-up, 18/19 (94.7%) patients had their arthrodesis united, and 16 (84.2%) of them were satisfied. Three (15.8%) patients were dissatisfied after arthrodesis. Two (10.5%) of them were dissatisfied because of pain despite fusion occurred.

Conclusion
The results of arthroscopic ankle arthrodesis for end-stage ankle arthritis in middle-aged active adults in selected patients were clinically and radiologically satisfactory and could be used as an alternative to open technique but with fewer hazards and complications.
