Retrospective Analysis: Preserving More Subcutaneous Tissue Shows no Increase the Risk of Breast Cancer Recurrence
Authors: Li Wenting , Liang Yinghui 
Published: September 2024

Background Radical mastectomy remains the cornerstone procedure for the treatment of breast cancer (BC). However, traditional radical surgeries often lead to complications such as local numbness, pulling sensations, and atrophy of the pectoralis major muscle. In contrast, BC radical surgeries that preserve more tissue have shown potential in reducing these complications. This retrospective study aims to analyze case data from our institution, focusing on the methods of surgeries that preserve more tissue and evaluating the safety and reliability of the follow-up results. Methods A retrospective observational study was conducted on cases diagnosed with BC between May 2018 and July 2019 at our institution. The cases were divided into three different surgical groups and followed up for a period of 5 years. The follow-up results were then discussed within each group. Results A total of 315 cases diagnosed with BC underwent regular follow-ups. The statistical analysis revealed an average age of 45 years and an average tumor size slightly over 2.2 cm, with early-stage BC (Stage I and II) accounting for 90.2% of the cases. The overall survival (OS) and disease-free survival times in the group undergoing total mastectomy with tissue preservation were comparable to those in the traditional radical mastectomy group and the breast-conserving plus radiotherapy group. Moreover, the complication rate, particularly the incidence of chest wall numbness and pulling sensations, was lower in the total mastectomy with tissue preservation group compared to the traditional radical mastectomy group. The overall average follow-up time was 64.4 months, with a recurrence and metastasis rate of 15.6% and an OS rate of 92.7%. Conclusion Based on our follow-up results, total mastectomy with more tissue preservation demonstrates comparable efficacy to breast-conserving surgery and traditional radical mastectomy. It can reduce some complications associated with traditional radical mastectomy and is beneficial for subsequent immediate and delayed breast reconstruction. This approach may be suitable for most patients with early to mid-stage breast cancer who do not wish to undergo breast-conserving surgery.

Background: American football is the most popular sport in the United States, with over 5.6 million people >6 years old playing the sport. Fractures in American football athletes are significant, as they compromise an athlete's performance and can also lead to prolonged recovery periods, affecting team dynamics and player careers. Analyzing these injuries is critical to evaluate preventive measures and tailor rehabilitation strategies to ensure the well-being and sustained peak performance of football athletes on and off the field. Purpose: To analyze the trend of American football fractures by body site, sex, and age in amateur athletes over a 20-year period between 2002 and 2021. Study Design: Descriptive epidemiology study. Methods: The National Electronic Injury Surveillance System (NEISS) database was queried to characterize football-related fractures and injuries from 2002 to 2021 in patients aged 0-99 years old. National injury estimates were calculated using sample weights. Chi-square analysis and one-way ANOVA were performed to compare categorical variables. Results: Of 56,809 cases of American football-related fractures over 20 years, patients aged 10 to 14 years had the highest incidence of fractures, composing 41.2% of all fractures (n = 23,389), and patients aged <18 years represented 88.8% of all fractures (n = 50,457). The median age of players when fractures occurred was 13 years. Upper extremity fractures (n = 41,863 [73.7%]) were the most common fracture reported compared with lower extremity and head, neck, and trunk fractures. Among upper extremity fractures, finger fractures had the highest prevalence (35.6%), followed by lower arm fractures (19.9%) and wrist fractures (13%). While most cases resulted in release after treatment (93.1%), 5.9% resulted in treatment and hospitalization. When analyzing trends in American football-related fractures over time, we observed the largest number of fractures in 2006 (n = 3664), while the smallest number of fractures occurred in 2020 (n = 1313). Also, a downward trend was found in American football-related fractures since 2006, with a mean of 101 fewer fractures each year. Conclusion: Our analysis showed that American football-related fractures diagnosed in the emergency department in the United States were most likely to occur in pediatric patients (10-18 years old). In addition, patients experiencing American football-related fractures were most likely to have an upper extremity fracture and not require hospitalization. The trend in American football-related fractures has been decreasing since 2006.

Abstract
Background
The onset of the COVID-19 pandemic drove a rapid and widespread shift to virtual care, followed by a gradual return to in-person visits. Virtual visits may offer more convenient access to care for some, but others may experience challenges accessing care virtually, and some medical needs must be met in-person. Experiences of the shift to virtual care and benefits of in-person care may vary by immigration experience (immigration status and duration), official language level, and age. We examined use of virtual care and return to in-person visits in the Canadian province of British Columbia (BC), comparing patterns by age and across immigration groups, including length of time in Canada and language level (official languages English and French) at time of arrival.

Methods
We used linked administrative health and immigration data to examine total primary care visits (virtual or in-person) and return to in-person visits during the COVID-19 pandemic (2019/20–2021/2) in BC. We examined the proportion of people with any primary care visits and with any in-person visits within each year as measures of access to primary care. We estimated the odds of any primary care visits and any in-person visits by immigration group and official language level assessed prior to arrival: non-immigrants, long-term immigrants, recent immigrants (< 5 years) with high assessed official language level and recent immigrants (< 5 years) with low assessed official language level (assessed prior to arrival), stratified by age.

Results
In general, changes in access to primary care (odds of any visits and odds of any in-person visits) were similar across immigration groups over the study period. However, we observed substantial disparities in access to primary care by immigration group among people aged 60 + , particularly in recent immigrants with low official language level (0.42, 0.40–0.45). These disparities grew wider over the course of the pandemic.

Conclusion
Though among younger adults changes in access to primary care between 2019–2021 were similar across immigration groups, we observed significant and growing inequities among older adults, with particularly limited access among adults who immigrated recently and with low assessed official language level. Targeted interventions to ensure acceptable, accessible care for older immigrants are needed.
Breastfeeding experiences of women with perinatal mental health problems: a systematic review and thematic synthesis
Authors: Billings Hayley , Horsman Janet , Soltani Hora , Spencer Rachael Louise 
Published: September 2024

Abstract
Background
Despite its known benefits, breastfeeding rates among mothers with perinatal mental health conditions are staggeringly low. Systematic evidence on experiences of breastfeeding among women with perinatal mental health conditions is limited. This systematic review was designed to synthesise existing literature on breastfeeding experiences of women with a wide range of perinatal mental health conditions.

Methods
A systematic search of five databases was carried out considering published qualitative research between 2003 and November 2021. Two reviewers conducted study selection, data extraction and critical appraisal of included studies independently and data were synthesised thematically.

Results
Seventeen articles were included in this review. These included a variety of perinatal mental health conditions (e.g., postnatal depression, post-traumatic stress disorders, previous severe mental illnesses, eating disorders and obsessive-compulsive disorders). The emerging themes and subthemes included: (1) Vulnerabilities: Expectations versus reality; Self-perception as a mother; Isolation. (2) Positive outcomes: Bonding and closeness; Sense of achievement. (3) Challenges: Striving for control; Inconsistent advice and lack of support; Concerns over medication safety; and Perceived impact on milk quality and supply.

Conclusions
Positive breastfeeding experiences of mothers with perinatal mental health conditions can mediate positive outcomes such as enhanced mother/infant bonding, increased self-esteem, and a perceived potential for healing. Alternatively, a lack of consistent support and advice from healthcare professionals, particularly around health concerns and medication safety, can lead to feelings of confusion, negatively impact breastfeeding choices, and potentially aggravate perinatal mental health symptoms. Appropriate support, adequate breastfeeding education, and clear advice, particularly around medication safety, are required to improve breastfeeding experiences for women with varied perinatal mental health conditions.

Published: September 2024

Abstract
Background
Maternal gestational diabetes (GDM), small (SGA) and large (LGA) for gestational age neonates are associated with increased morbidity in both mother and child. We studied how different levels of first trimester pregnancy associated plasma protein-A (PAPP-A) and free beta human chorionic gonadotropin (fβ-hCG) were associated with SGA and LGA in GDM pregnancies and controls.

Methods
Altogether 23 482 women with singleton pregnancies participated in first trimester combined screening and delivered between 2014 and 2018 in Northern Finland and were included in this retrospective case-control study. Women with GDM (n = 4697) and controls without GDM (n = 18 492) were divided into groups below 5th and 10th or above 90th and 95th percentile (pc) PAPP-A and fβ-hCG MoM levels. SGA was defined as a birthweight more than two standard deviations (SD) below and LGA more than two SDs above the sex-specific and gestational age-specific reference mean. Odds ratios were adjusted (aOR) for maternal age, BMI, ethnicity, IVF/ICSI, parity and smoking.

Results
In pregnancies with GDM the proportion of SGA was 2.6% and LGA 4.5%, compared to 3.3% (p = 0.011) and 1.8% (p < 0.001) in the control group, respectively. In ≤ 5th and ≤ 10th pc PAPP-A groups, aORs for SGA were 2.7 (95% CI 1.5–4.7) and 2.2 (95% CI 1.4–3.5) in the GDM group and 3.8 (95% CI 3.0–4.9) and 2.8 (95% CI 2.3–3.5) in the reference group, respectively. When considering LGA, there was no difference in aORs in any high PAPP-A groups. In the low ≤ 5 percentile fβ-hCG MoM group, aORs for SGA was 2.3 (95% CI 1.8–3.1) in the control group. In fβ-hCG groups with GDM there was no association with SGA and the only significant difference was ≥ 90 percentile group, aOR 1.6 (95% CI 1.1–2.5) for LGA.

Conclusion
Association with low PAPP-A and SGA seems to be present despite GDM status. High PAPP-A levels are not associated with increased LGA risk in women with or without GDM. Low fβ-hCG levels are associated with SGA only in non-GDM pregnancies.
VUS next in rare diseases? Deciphering genetic determinants of biomolecular condensation

Published: September 2024

AbstractThe diagnostic odysseys for rare disease patients are getting shorter as next-generation sequencing becomes more widespread. However, the complex genetic diversity and factors influencing expressivity continue to challenge accurate diagnosis, leaving more than 50% of genetic variants categorized as variants of uncertain significance.Genomic expression intricately hinges on localized interactions among its products. Conventional variant prioritization, biased towards known disease genes and the structure-function paradigm, overlooks the potential impact of variants shaping the composition, location, size, and properties of biomolecular condensates, genuine membraneless organelles swiftly sensing and responding to environmental changes, and modulating expressivity.To address this complexity, we propose to focus on the nexus of genetic variants within biomolecular condensates determinants. Scrutinizing variant effects in these membraneless organelles could refine prioritization, enhance diagnostics, and unveil the molecular underpinnings of rare diseases. Integrating comprehensive genome sequencing, transcriptomics, and computational models can unravel variant pathogenicity and disease mechanisms, enabling precision medicine. This paper presents the rationale driving our proposal and describes a protocol to implement this approach. By fusing state-of-the-art knowledge and methodologies into the clinical practice, we aim to redefine rare diseases diagnosis, leveraging the power of scientific advancement for more informed medical decisions.
Why make it if you can take it: review on extracellular cholesterol uptake and its importance in breast and ovarian cancers
Authors: Lauridsen Anna Røssberg , Skorda Aikaterini , Winther Nuggi Ingholt , Bay Marie Lund , Kallunki Tuula 
Published: September 2024

AbstractCholesterol homeostasis is essential for healthy mammalian cells and dysregulation of cholesterol metabolism contributes to the pathogenesis of various diseases including cancer. Cancer cells are dependent on cholesterol. Malignant progression is associated with high cellular demand for cholesterol, and extracellular cholesterol uptake is often elevated in cancer cell to meet its metabolic needs. Tumors take up cholesterol from the blood stream through their vasculature. Breast cancer grows in, and ovarian cancer metastasizes into fatty tissue that provides them with an additional source of cholesterol. High levels of extracellular cholesterol are beneficial for tumors whose cancer cells master the uptake of extracellular cholesterol. In this review we concentrate on cholesterol uptake mechanisms, receptor-mediated endocytosis and macropinocytosis, and how these are utilized and manipulated by cancer cells to overcome their possible intrinsic or pharmacological limitations in cholesterol synthesis. We focus especially on the involvement of lysosomes in cholesterol uptake. Identifying the vulnerabilities of cholesterol metabolism and manipulating them could provide novel efficient therapeutic strategies for treatment of cancers that manifest dependency for extracellular cholesterol.
Trypanosoma cruzi reprograms mitochondrial metabolism within the anterior midgut of its vector Rhodnius prolixus during the early stages of infection
Authors: Ouali Radouane , Vieira Larissa Rezende , Salmon Didier , Bousbata Sabrina 
Published: September 2024

Abstract
Background
Trypanosoma cruzi is transmitted to humans by hematophagous bugs belonging to the Triatominae subfamily. Its intra-vectorial cycle is complex and occurs exclusively in the insect's midgut. Dissecting the elements involved in the cross-talk between the parasite and its vector within the digestive tract should provide novel targets for interrupting the parasitic life cycle and affecting vectorial competence. These interactions are shaped by the strategies that parasites use to infect and exploit their hosts, and the host's responses that are designed to detect and eliminate parasites. The objective of the current study is to characterize the impact of T. cruzi establishment within its vector on the dynamics of its midgut.

Methods
In this study, we evaluated the impact of T. cruzi infection on protein expression within the anterior midgut of the model insect Rhodnius prolixus at 6 and 24 h post-infection (hpi) using high-throughput quantitative proteomics.

Results
Shortly after its ingestion, the parasite modulates the proteome of the digestive epithelium by upregulating 218 proteins and negatively affecting the expression of 11 proteins involved in a wide array of cellular functions, many of which are pivotal due to their instrumental roles in cellular metabolism and homeostasis. This swift response underscores the intricate manipulation of the vector's cellular machinery by the parasite. Moreover, a more in-depth analysis of proteins immediately induced by the parasite reveals a pronounced predominance of mitochondrial proteins, thereby altering the sub-proteomic landscape of this organelle. This includes various complexes of the respiratory chain involved in ATP generation. In addition to mitochondrial metabolic dysregulation, a significant number of detoxifying proteins, such as antioxidant enzymes and P450 cytochromes, were immediately induced by the parasite, highlighting a stress response.

Conclusions
This study is the first to illustrate the response of the digestive epithelium upon contact with T. cruzi, as well as the alteration of mitochondrial sub-proteome by the parasite. This manipulation of the vector's physiology is attributable to the cascade activation of a signaling pathway by the parasite. Understanding the elements of this response, as well as its triggers, could be the foundation for innovative strategies to control the transmission of American trypanosomiasis, such as the development of targeted interventions aimed at disrupting parasite proliferation and transmission within the triatomine vector.

A methodology for appropriate withdrawal of tsunami warnings based on numerical simulations
Authors: Shinmoto Naoko , Baba Toshitaka 
Published: September 2024

AbstractThis study performed large-scale numerical simulations for predicting the attenuation of tsunamis caused by the 2011 Tohoku, Japan, and 2010 Maule, Chile earthquakes, recorded at Japanese tide gauges. Tsunami amplitude waveforms were generated by computing the moving root-mean-square of the data for quantitative analyses. Sensitivity analysis showed that tsunami nonlinearity and computational grid intervals near the tide gauges significantly impact the prediction of tsunami attenuation. The predicted withdrawal times of tsunami warnings agreed with the observations; however, time discrepancies were observed for advisory withdrawals at several stations. Using the proposed method, we predicted the warning period of a great interplate earthquake in the Nankai Trough to be approximately one day. These findings can provide critical information for disaster prevention because the withdrawal of warnings is directly related to permission to enter coastal areas affected by the tsunami, whereas unnecessarily long warnings hinder rescue operations.

Published: September 2024

AbstractThe electrical conductivity of the earth’s mantle can provide important information about geodynamic phenomena. East Asia is associated with complex tectonics and geodynamic processes. Hence, it is necessary to better understand the deep structure beneath East Asia. In this study, geomagnetic data obtained from East Asian observatories are employed to image the conductivity structure of the mantle at depths ranging from 410 to 900 km. First, the data are processed using the modified bounded influence remote reference processing (BIRRP) method and the ratio method is used to correct for the ocean effect. Thereafter, the stable C-response curves at the 27 observatories are estimated, and 1D electrical conductivity models for these observatories are established using the L-BFGS method. The conductivity-depth profiles reveal a heterogeneous distribution of the electrical conductivity beneath East Asia. The mantle transition zone (MTZ) beneath East China and Japan is found to be more conductive, whereas the MTZ beneath central and southern regions of China is more resistive. In East China, the dehydration of the stagnant Pacific slab may lead to an increase in the conductivity of the mantle minerals. There is also the possibility of upwelling of the thermal material from the lower mantle beneath the Japanese Island arc. In Northwest China, there exists a large high-conductive body beneath the Tarim area, which could indicate an upwelling of the Tarim mantle plume. Our results provide insights into the deep structure of the earth at the mantle scale.
Exploring the impact of internet usage on individuals’ social status discordance: evidence from China
Authors: Ding Guoxuan , Meng Xiao , Fan Xiaoyan 
Published: September 2024

AbstractThis study examines the impact of internet usage frequency and behavior on social status discordance using CSS2021 data, and adopts a causal random forest model to test the heterogeneity of the impact of internet usage on social status discordance. The results reveal a clear inconsistency between objective and subjective social status among Chinese residents. In addition, increasing internet usage frequency can make actors more inclined to underestimate their social status. Moreover, capital enhancement through the internet significantly reduces the likelihood of status inflation. Finally, individuals with higher social status are less likely to have an upward bias in status cognition than those with lower social status when they use the internet frequently and use it for capital enhancement. These findings advance our understanding of social status identification among Chinese residents and provide different perspectives for studying social stratification in the digital age.
