The 2430 draft reference genomes comprised of 20 or more contigs were used to simulate partial and contaminated genomes reflecting the characteristics of assembled contigs. Under this random contig model, genomes were generated by randomly removing contigs until the simulated genome reached or fell below a target completeness level. Contamination was introduced by randomly adding contigs with replacement from a single randomly selected genome until the desired level of contamination was reached or exceeded. These 2430 draft genomes were also used to generate genomes reflecting the limitations of metagenomic binning methods that rely on the statistical properties of contigs (e.g., tetranucleotide signature, coverage) to establish putative population genomes. To simulate this, partial genomes were generated by randomly removing contigs with a probability inversely proportional to their length until the simulated genome reached or fell below a target completeness level. Contamination was introduced by randomly selecting another draft reference genome and adding contigs from this genome with a probability inversely proportional to length until the desired level of contamination was reached or exceeded.

The incremental lifetime cancer risk (ILCR) was used to assess the inhalation risk for the population in the Greater Salvador, where the bus station and the coastal site are located. ILCR is calculated as: where SF is the cancer slope factor of BaP, which was 3.14 (mg kg−1 d−1)−1 for inhalation exposure60 (link), EF (day year−1) represents the exposure frequency (365 days year−1), ED (year) represents exposure duration to air particles (year), cf is a conversion factor (1 × 10−6), AT (days) means the lifespan of carcinogens in 70 years (70 × 365 = 25,550 days)70 ,72 , and BW (kg) is the body weight of a subject in a target population71 .
The risk assessment was performed considering four different target groups in the population: adults (>21 years), adolescents (11–16 years), children (1–11 years), and infants (<1 year). The IR for adults, adolescents, children, and infants were 16.4, 21.9, 13.3, 6.8 m3 day−1, respectively. The BW was considered 80 kg for adults, 56.8 kg for adolescents, 26.5 kg for children and 6.8 kg for infants70 .
All of the found data was reported as completed weeks except for the German Perinatal Statistics, which were reported as actual daily weights [14 (link)]. To combine the datasets, the German data was temporarily converted to completed weeks. A final step converted the meta-analyses to actual age.
a) Corrected gestational ages through fetal ultrasound and/or infant assessment and/or statistical correction;
b) Data percentiles at 24 weeks gestational age or lower;
c) Sample of at least 25,000 babies, with more than 500 infants aged less than 30 weeks;
d) Separate data on females and males;
e) Data available numerically in published form or from authors,
f) Data collected within the past 25 years (1987 to 2012) to account for any secular trends.

Syphilis is an STI that can cause long-term complications if not treated correctly. Symptoms in adults are divided into stages. These stages are primary, secondary, latent, and late syphilis. In pregnant women, having syphilis can lead to giving birth to a low birth weight baby. It can also lead to delivering the baby too early or stillborn (CDC fact sheet, 2015).
Although T. pallidum cannot be grown in culture, there are many tests for the direct and indirect diagnosis of syphilis. Still, there is no single optimal test. Direct diagnostic methods include the detection of T. pallidum by microscopic examination of fluid or smears from lesions, histological examination of tissues or nucleic acid amplification methods such as polymerase chain reaction (PCR). Indirect diagnosis is based on serological tests for the detection of antibodies (Ratnam S, Can J Infect Dis Med Microbiol 2005). Treatment includes a single dose of intramuscular administration of penicillin (2.4 Million units).
In some embodiments, the disclosed device can be used to detect syphilis infections from menstrual blood or cervicovaginal fluids.

Bacterial Vaginosis (BV) is an infection caused when too much of certain bacteria change the normal balance of bacteria in the vagina. Bacterial vaginosis (BV) is one of the most common lower genital tract conditions, occurring in 35% of women attending sexually transmitted infection (STI) clinics, 15% to 20% of pregnant women, and 5% to 15% of women attending gynecology clinics (Eschenbach D A, Am J Obstet Gynecol 1993). Pregnant women with BV are more likely to have babies who are born premature (early) or with low birth weight than women who do not have BV while pregnant. Low birth weight means having a baby that weighs less than 5.5 pounds at birth (CDC fact sheet, 2015).
Diagnosis of BV is typically done through a vaginal swab to assess the presence and balance of certain bacteria within the vaginal flora through PCR. A wet mount, whiff test, or pH test can also be performed in order to diagnose a possible bacterial infection.
In some embodiments, the disclosed device can be used to detect bacterial vaginosis from menstrual blood or cervicovaginal fluids.
Example 2
Chlamydia is a common STI that is caused by the bacterium Chlamydia trachomatis. Transmission occurs during vaginal, anal, or oral sex, but the bacterium can also be passed from an infected mother to her baby during vaginal childbirth. It is estimated that about 1 million individuals in the United States are infected with this bacterium, making chlamydia one of the most common STIs worldwide. Like gonorrhea, chlamydial infection is asymptomatic for a majority of women. If symptoms are present, they include unusual vaginal bleeding or discharge, pain in the abdomen, painful sexual intercourse, fever, painful urination or the urge to urinate more frequently than usual. Of those who develop asymptomatic infection, approximately half may develop PID. Infants born to mothers with chlamydia may suffer from pneumonia and conjunctivitis, which may lead to blindness. They may also be subject to spontaneous abortion or premature birth.
Diagnosis of chlamydial infection is usually done by nucleic acid amplification techniques, such as PCR, using samples collected from cervical swabs or urine specimens (Gaydos et al., J. Clin. Microbio., 42:3041-3045; 2004). Treatment involves various antibiotic regimens.
In some embodiments, the disclosed device can be used to detect chlamydial infections from menstrual blood or cervicovaginal fluids.

Fertility—Progesterone is one of the most important hormones for pregnancy with myriad functions from ensuring implantation of the egg into a healthy uterine wall, to ensuring embryo survival and prevention of immune rejection of the developing baby. Many other hormones act in concert with progesterone, like Follicular Stimulating Hormone (FSH) and Luteinizing Hormone (LH) and can be used to assess optimal fertility windows on a monthly basis. And in fact an over dominant production of estrogen can lead to progesterone deficiency and thus difficulty getting or staying pregnant. It is important that women not only monitor FSH and LH to determine optimal fertility for getting pregnant, but ensure that sufficient levels or progesterone are being produced to ensure pregnancy and viability of the fetus. A study from the British Medical Journal, 2012, demonstrated that a single progesterone level test can help discriminate between viable and nonviable pregnancies. Among women who had an ultrasound, 73 percent had nonviable pregnancies. But among women with progesterone levels below 3 to 6 nanograms per milliliter, the probability of a nonviable pregnancy rose to more than 99 percent (Gallos L et al. British Medical J, 2012).
Perimenopause—Monitoring hormone levels during the menopausal transition may help women better understand important changes in their body and allow them to make more informed decisions about health, diet, and lifestyle. According to Hale G E (Best Pract Res Clin Obstet Gynaecol, 2009), data from endocrine studies on women throughout the menopausal transition show changes in levels of steroid hormones and gonadotropins (Progesterone, Estrodiol, LH, FSH and AMH) and follicle-stimulating hormone undergoes the first detectable change while menstrual cycles remain regular. Erratic and less predictable changes in steroid hormones follow, especially with the onset of irregular cycles. Later serum hormone studies on the inhibins and anti-Mullerian hormone established that diminishing ovarian follicle number contributes to the endocrine changes with advancing reproductive age.
Many fertility issues revolve around genetic, anatomical or other disorders that may either prevent a woman from becoming pregnant and/or staying pregnant. Some of these disorders include hormonal imbalances, diabetes, a short or insufficient cervix, and acute or chronic infections. A cascade of genes has been implicated in the occurrence of getting and staying pregnant. These genes have been studied using genotyping, gene expression, and proteomic analysis to assess a woman's ability to stay pregnant.
In some embodiments the disclosed device focuses on detecting levels of Progesterone, LH, FSH, Estrodiol, AMH, genotyping, gene expression through RNA and methylome sequencing, qPCR and proteomic analysis for fertility and menopause management from menstrual blood or cervicovaginal fluid.
Underlining the importance of understanding sofa surfing as a gateway to exclusion many women detailed the inherent danger and vulnerability in needing to rely on others to find a place to stay:
You get to know people the wrong way sometimes. It’s really sad when you need, you know you’re doing a very dangerous thing... it also exposes the anger. Men who hate women. I always forget the word, misogynist. You become a needy woman, you meet a misogynist (Tracy).
I was couch surfing but there was many a night where I’d have to get out of there because they assume that means sex in bed and rock and roll, you know ... Because you owe something. And once you owe something, they can take anything. It’s dirty. It’s a really ugly, you know the word rape is um, is so misunderstood even as a victim of it because if you’re doing it for a place to stay, am I being raped? Or am I f****** him so I can have somewhere to sleep. You know what I mean? Excuse my language. It’s a horrendous place to be.
