Sex differences in upper tract urothelial carcinomas.
Current Opinion in Urology
|February 15, 2019
Summary
Sex differences in upper tract urothelial carcinoma (UTUC) impact diagnosis and outcomes, with varied findings on clinicopathologic features. Further research into genetic and environmental factors is needed to fully understand these sex-based variations.
Area of Science:
- Urology
- Oncology
- Epidemiology
Background:
- Upper tract urothelial carcinoma (UTUC) exhibits potential sex-based differences.
- Existing literature presents mixed findings on how sex influences UTUC clinicopathologic features and outcomes.
- Disparities in diagnosis time and environmental exposures may contribute to observed sex-based variations.
Purpose of the Study:
- To review contemporary sex-specific differences in upper tract urothelial carcinoma (UTUC).
- To evaluate diagnostic considerations, clinicopathologic features, oncologic outcomes, environmental exposures, and regional variations in UTUC by sex.
- To elucidate the impact of sex on UTUC.
Main Methods:
- Literature review of contemporary studies on UTUC.
- Analysis of diagnostic considerations, clinicopathologic features, and oncologic outcomes.
- Examination of environmental exposures and regional variations in UTUC by sex.
Main Results:
- Contemporary studies show mixed findings regarding the effect of sex on UTUC clinicopathologic features and oncologic outcomes.
- Time to diagnosis in UTUC appears to differ between men and women.
- Geographic variations and environmental risk factors significantly influence UTUC epidemiology and outcomes, potentially by sex.
Conclusions:
- A definitive global consensus on the effect of sex on UTUC characteristics and outcomes is lacking.
- Differences in diagnosis time, risk factors, and regional variation by sex warrant consideration.
- Further research into genetic, anatomic, physiologic, and socioeconomic factors is crucial for understanding sex-based effects in UTUC.

Anatomy of Respiratory System I: Upper Respiratory Tract
5.1K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Electric Potential and Potential Difference
5.7K
Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy decreases. The potential energy per unit charge is defined as the electric potential. The electric potential is independent of the test charge.
When a test charge moves from the initial to the final position, the electric potential difference between those positions is defined as the ratio of the change in the potential energy to the charge on the...

Difference from Background: Limit of Detection
8.3K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.

Identifying Statistically Significant Differences: The F-Test
3.7K
The F-test is used to compare two sample variances to each other or compare the sample variance to the population variance. It is used to decide whether an indeterminate error can explain the difference in their values. The underlying assumptions that allow the use of the F-test include the data set or sets are normally distributed, and the data sets are independent of each other. The test statistic F is calculated by dividing one variance by another. In other words, the square of one standard...

Sum and Difference OpAmps
1.4K
Operational amplifiers (op-amps) are versatile devices that extend beyond amplification. In this context, two specific op-amp configurations are explored: the summing and difference amplifiers.
A summing amplifier, or an adder, utilizes an op-amp to merge multiple input signals into a single output signal. When audio signals are introduced into its input channels, the input resistors initiate currents that traverse feedback resistors, resulting in an output voltage. Applying Kirchhoff's current...
