Among 116 persons who inject drugs, site-specific specimen collection preferences aligned closely with reported sexual risk behaviours. The study found high awareness of STI transmission, yet outreach through syringe exchange programmes paired with education on site-specific screening could improve case finding in this population.

Daily oral HIV pre-exposure prophylaxis demonstrated high acceptability and adherence among high-risk gay and bisexual men when monitored by dried blood spot analysis, with no HIV seroconversions over one year but frequent sexually transmitted infections. The study shows dried blood spot testing can support adherence monitoring in decentralised prevention programmes, though renal function requires surveillance.

Urine self-sampling detected high-risk HPV with 51% sensitivity and 96% specificity compared to clinician-collected cervical samples, showing moderate overall agreement but substantial agreement in women aged 40 and older. This indicates urine testing could serve as a viable screening tool in low-resource settings where clinical collection is challenging, particularly for older women.

Among 250 infertile Iranian men, self-collected first-void urine enabled decentralised detection of Chlamydia trachomatis, yet infection status showed no correlation with sperm chromatin condensation or DNA fragmentation. The study validates first-void urine for remote STI screening in fertility assessment, while indicating sperm quality markers are independent of Chlamydia infection.

Self-collected urine from men and vaginal swabs from women detected Chlamydia trachomatis in 8.8% of affluent Chilean youth under 25 years. Having some college education was protective, while a higher number of sexual partners and postcoital bleeding in women were risk factors, showing that decentralised STI screening via self-sampling produces valid epidemiological and clinical insights.

Self-collection of urine and vaginal swabs for chlamydia and gonorrhoea testing increased screening uptake by 28.5% in male and 13.7% in female university students. Female students tested positive at a markedly higher rate via self-collection (12.4%) than via clinician collection (4.8%), indicating that decentralised self-testing reaches higher-risk individuals and improves case detection.

In 250 Iranian infertile couples followed for 24 months, detection of Chlamydia trachomatis DNA in first-void urine, semen or serum antibodies did not predict tubal factor infertility, pregnancy rate or outcome. This indicates that patient-collected first-void urine screening for these organisms may have limited clinical utility in fertility assessment.

In men with Mycoplasma genitalium positive non-chlamydial urethritis, higher leukocyte counts in first-void urine predicted persistence of the organism after antimicrobial chemotherapy; a threshold of 10 leukocytes per microlitre between days 18 and 24 was most strongly associated with treatment failure.

Leucocyte esterase dipstick testing of first-void urine from 292 asymptomatic Aboriginal men in central Australia detected gonorrhoea or chlamydia with 66.7% sensitivity and 90.7% specificity, giving a negative predictive value of 93.7%. This supports use of the dipstick to guide immediate empirical treatment in primary care, especially when combined with age ≤35 years where specificity rose to 94.7%.

First-void urine self-collection detected bacterial vaginosis with sensitivity comparable to vaginal swabs when analysed by quantitative PCR for seven key vaginal bacteria. This supports decentralised screening for BV and sexually transmitted infections using patient-collected samples.

Urine-based HPV DNA testing demonstrated 76% agreement with cervical sampling, correctly identifying 100% of uninfected but only 65% of infected women in a high-risk population. All 12 discrepant pairs were urine-negative/cervix-positive, confirming that self-collected urine is substantially less sensitive than cervical sampling for HPV screening.

First-void urine specimens yielded accurate bacterial vaginosis diagnosis by qPCR for Megasphaera type 1 and Prevotella spp, with sensitivity and specificity matching vaginal swabs. This supports decentralised screening through non-invasive self-collection, removing the need for clinician-collected vaginal samples.

First-void urine sampling detected Mycoplasma genitalium in only 2 of 145 infertile men and in none of 49 asymptomatic controls, a prevalence markedly lower than in other reported cohorts. This indicates that decentralised STI screening can produce unexpectedly low yields in certain populations, underscoring the need for local validation of patient-centric diagnostic strategies.

In 230 women, HPV detection in self-collected urine showed 90 per cent agreement with cervical sampling (κ=0.80), with 97 per cent concordance for high-risk types. High viral load in urine correlated with cytological abnormalities, suggesting urine self-sampling could enable decentralised cervical cancer screening with good accuracy.

In an urban emergency department, only 20% of women aged 19-25 presenting with dysuria and diagnosed with urinary tract infection were tested for chlamydia, and 21% of those tested were positive, yet only 42% of positive cases received effective treatment; the authors argue that routine sexual history taking and the availability of self-administered vaginal swab and first-void urine chlamydia tests could improve detection.

Among 1381 asymptomatic patients under 30 at French screening clinics, 7.6% tested positive for Chlamydia trachomatis, 0.58% for Mycoplasma genitalium, and 0.36% for Neisseria gonorrhoeae by PCR of first-void urine. The findings support systematic chlamydia screening but not gonorrhoea or mycoplasma screening in this decentralised, patient-centric setting.

In a cross-sectional study of 409 men who have sex with men in Shenzhen, the overall prevalence of Mycoplasma genitalium was 8.1%, with 3.4% positivity in first-void urine and 5.4% in rectal swabs; urethral infection was associated with more heterosexual behaviours and recent unprotected anal intercourse, while rectal infection was linked to HIV infection, indicating the need for targeted screening of self-collected specimens in this population.
