Clinical and Biochemical Outcomes in Transgender Individuals Undergoing Hormone Therapy: Protocol for a Systematic Review
Authors: Sattora Emily , Teelin Karen , Prendergast Christopher , Smith Abigail , Evans James , Imdad Aamer 
Published: August 2024

Background
Monitoring of various clinical outcomes and parameters, such as lipid levels, is recommended in transgender individuals undergoing hormone therapies. However, comprehensive data to inform these recommendations is scarce.

Objective
This study aims to conduct a systematic review and meta-analysis to synthesize evidence from existing literature on the effect of exogenous hormone therapy on clinical and biochemical outcomes for transgender adolescents and adults.

Methods
We will search multiple electronic databases and will include prospective and retrospective observational studies with and without a control group. The study population will include transgender individuals undergoing hormone therapy with testosterone or estrogen. Comparisons will include age-matched, cisgender individuals and changes from baseline. Primary outcomes include changes in or the development of abnormal lipid parameters. Secondary outcomes include BMI, weight, height, and blood pressure for age, serum testosterone or estrogen levels, and development of disease including hypertension, diabetes, fatty liver disease, obesity, adverse cardiac events, as well as all-cause mortality. The meta-analysis will pool the studies where applicable, and meta-regressions will be conducted to evaluate effect modifiers. The GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach will be used to evaluate the overall certainty of evidence.

Results
We will summarize the selection of the eligible studies using a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flowchart. The results will be presented in a table summarizing the evidence. Data collection is ongoing, and the paper is expected to be published in Spring 2025.

Conclusions
This systematic review will summarize and evaluate the evidence of the clinical and biochemical outcomes associated with hormone therapies for transgender individuals.

Optimizing a Classification Model to Evaluate Individual Susceptibility in Noise-Induced Hearing Loss: Cross-Sectional Study
Authors: Li Shiyuan , Yu Xiao , Ma Xinrong , Wang Ying , Guo Junjie , Wang Jiping , Shen Wenxin , Dong Hongyu , Salvi Richard , Wang Hui , Yin Shankai

Abstract

Background
Noise-induced hearing loss (NIHL), one of the leading causes of hearing loss in young adults, is a major health care problem that has negative social and economic consequences. It is commonly recognized that individual susceptibility largely varies among individuals who are exposed to similar noise. An objective method is, therefore, needed to identify those who are extremely sensitive to noise-exposed jobs to prevent them from developing severe NIHL.

Objective
This study aims to determine an optimal model for detecting individuals susceptible or resistant to NIHL and further explore phenotypic traits uniquely associated with their susceptibility profiles.

Methods
Cross-sectional data on hearing loss caused by occupational noise were collected from 2015 to 2021 at shipyards in Shanghai, China. Six methods were summarized from the literature review and applied to evaluate their classification performance for susceptibility and resistance of participants to NIHL. A machine learning (ML)–based diagnostic model using frequencies from 0.25 to 12 kHz was developed to determine the most reliable frequencies, considering accuracy and area under the curve. An optimal method with the most reliable frequencies was then constructed to detect individuals who were susceptible versus resistant to NIHL. Phenotypic characteristics such as age, exposure time, cumulative noise exposure, and hearing thresholds (HTs) were explored to identify these groups.

Results
A total of 6276 participants (median age 41, IQR 33‐47 years; n=5372, 85.6% men) were included in the analysis. The ML-based NIHL diagnostic model with misclassified subjects showed the best performance for identifying workers in the NIHL-susceptible group (NIHL-SG) and NIHL-resistant group (NIHL-RG). The mean HTs at 4 and 12.5 kHz showed the highest predictive value for detecting those in the NIHL-SG and NIHL-RG (accuracy=0.78 and area under the curve=0.81). Individuals in the NIHL-SG selected by the optimized model were younger than those in the NIHL-RG (median 28, IQR 25‐31 years vs median 35, IQR 32‐39 years; P<.001), with a shorter duration of noise exposure (median 5, IQR 2‐8 years vs median 8, IQR 4‐12 years; P<.001) and lower cumulative noise exposure (median 90, IQR 86‐92 dBA-years vs median 92.2, IQR 89.2‐94.7 dBA-years; P<.001) but greater HTs (4 and 12.5 kHz; median 58.8, IQR 53.8‐63.8 dB HL vs median 8.8, IQR 7.5‐11.3 dB HL; P<.001).

Conclusions
An ML-based NIHL diagnostic model with misclassified subjects using the mean HTs of 4 and 12.5 kHz was the most reliable method for identifying individuals susceptible or resistant to NIHL. However, further studies are needed to determine the genetic factors that govern NIHL susceptibility.

Published: August 2024

Betacyanin là nhóm chất màu tự nhiên quan trọng dùng để thay thế chất màu tổng hợp do đặc tính bền, không độc hại và có nhiều hoạt tính sinh học có lợi cho sức khỏe. Trong nghiên cứu này, betacyanin từ vỏ quả thanh long ruột trắng (Hylocereus undatus) được chiết bằng ethanol và xử lý siêu âm. Ảnh hưởng của các thông số đến hiệu suất chiết và bền màu của betacyanin đã được khảo sát. Kết quả cho thấy việc bổ sung các acid hữu cơ vào ethanol làm tăng đáng kể hiệu quả chiết và bền màu của betacyanin, trong đó ascorbic acid hiệu quả hơn citric acid. Điều kiện chiết tốt nhất đạt được là 40% (v/v) ethanol, 0,005 mol/L ascorbic acid, pH 2, 1/20 g/mL tỷ lệ rắn lỏng, 40oC, và 20 phút. Hiệu suất chiết betacyanin là 0,472 mg/g và sự phân hủy màu sau 24 giờ là nhỏ hơn 5%. Cao chiết chứa betacyanin có hoạt tính kháng oxi hóa và gây độc tế bào ung thư biểu bì KB. Như vậy, vỏ quả thanh long là nguồn nguyên liệu tiềm năng để sản xuất betacyanin, mang đến giá trị kinh tế và môi trường.
