RESUMO
We compared self-collected oral fluid swab specimens with and without clinician supervision, clinician-supervised self-collected anterior nasal swab specimens, and clinician-collected nasopharyngeal swab specimens for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Supervised oral fluid and nasal swab specimens performed similarly to clinician-collected nasopharyngeal swab specimens. No sample type could detect SARS-CoV-2 infections amongst all positive participants.

OBJECTIVE: To measure the frequencies of sexually transmitted infections (STIs) and adverse pregnancy outcomes among women receiving either aetiological testing or syndromic management for STIs. DESIGN: Non-randomised prospective cohort study. SETTING: Primary healthcare facilities in Tshwane, South Africa. POPULATION: HIV-infected pregnant women attending antenatal care services. METHODS: Participants were enrolled to receive aetiological testing using Xpert® CT/NG and Xpert® TV assays or standard syndromic management. Outcome data were collected at the postnatal care visit (≤30 days from delivery) and from maternity records. Enrolment gestational age-adjusted relative risk (aRR) was calculated. MAIN OUTCOME MEASURES: STI prevalence at postnatal visit, and frequency of adverse pregnancy outcomes (preterm birth, low birthweight). RESULTS: We enrolled 841 women. The prevalence of any STI at baseline was 40%; Chlamydia trachomatis 30%, Neisseria gonorrhoeae 5.6%, Trichomonas vaginalis 20%. The prevalence of STIs at postnatal care was lower among those receiving aetiological testing compared with those receiving syndromic management (14% versus 23%; aRR 0.61; 95% CI 0.35-1.05). No difference was observed between study groups for frequency of preterm birth (23% versus 23%; aRR 1.2, 95% CI 0.81-1.8) and low birth weight (15% versus 13%; aRR 1.1, 95% CI 0.66-1.7). CONCLUSIONS: Aetiological testing provides an effective intervention to reduce the high burden of STIs in pregnant women in South Africa; however, the optimal implementation strategy remains to be determined. TWEETABLE ABSTRACT: Aetiological testing effectively reduces the burden of sexually transmitted infections in pregnancy.

BACKGROUND: Current syphilis tests cannot distinguish between active and past syphilis among patients with serofast rapid plasma reagin (RPR) titers. We investigated whether cytokine profiles might provide insight in the differentiation of active and treated syphilis. METHODS: We collected quarterly serum samples from participants at risk for incident syphilis in a prospective cohort study of men and male-to-female transgender women. We defined incident syphilis as a new RPR titer ≥ 1:8 or a fourfold increase from a prior RPR titer and a positive Treponema pallidum particle agglutination assay. We measured cytokine expression using a 63-multiplex bead-based Luminex assay (eBiosciences/Affymetrix, San Diego, California, USA). We used tertile bins and Chi square tests to identify differences in proportions of cytokines between samples from patients with active and treated syphilis. We constructed a network of cytokine profiles from those findings. We used R software (R version 3.4.1, R, Vienna, Austria) to fit models. RESULTS: We identified 20 pairs of cytokines (out of 1953 possible pairs) that differed between active and treated syphilis. From those, we identified three cytokine networks of interest: an Eotaxin-Rantes-Leptin network, a Mig-IL1ra-Trail-CD40L network, and an IL12p40-IL12p70 network. CONCLUSIONS: Differences in cytokine profiles are present among men and male-to-female transgender women with active and treated syphilis. Cytokine assays may be a potentially useful tool for identifying active syphilis among patients with serologic syphilis reactivity.

HIV infections in Peru are concentrated among men who have sex with men (MSM) and transgender women (TW). HIV testing rates among them remain low, delaying entrance into care. We assessed the prevalence of frequent HIV testing (at least every 6 months) and associated factors among 310 MSM and TW who attend sexual health clinics in Lima, Peru, and who reported that they were HIV seronegative or unaware of their status. Only 39% of participants tested frequently, and 22% had never tested; 29% reported that they were at low or no risk for acquiring HIV. Reporting low or no risk for acquiring HIV was associated with frequent testing (adjusted prevalence ratio [aPR] = 1.53, 95% CI 1.13-2.08); those reporting unprotected anal sex were less likely to test frequently (aPR = 0.66, 95% CI 0.50-0.87). HIV prevalence was 12% and did not vary by risk perception categories. This at-risk population tests infrequently and may not understand the risk of having unprotected sex.

Background: Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) infections may increase the risk of vertical transmission of the human immunodeficiency virus (HIV). In resource-limited settings, symptomatic screening, and syndromic management of sexually transmitted infections (STIs) during pregnancy continue to be the standard of care. In the absence of diagnostic testing, asymptomatic infections in pregnant women go untreated. Objective: To describe the acceptability and feasibility of integrating diagnostic STI screening into first antenatal care visits for HIV-infected pregnant women. Methods: HIV-infected pregnant women were recruited during their first antenatal care visit from three antenatal care clinics in Tshwane District, South Africa, between June 2016 and October 2017. Self-collected vaginal swabs were used to screen for CT, NG, and TV with a diagnostic point-of-care (POC) nucleic acid amplification test. Those with STIs were provided treatment per South African national guidelines. Results: Of 442 eligible women, 430 (97.3%) agreed to participate and were tested. Of those with a positive STI test result (n = 173; 40.2%), 159 (91.9%) received same-day results and treatment; 100% of STI-infected women were treated within seven days. Conclusions: Integration of POC diagnostic STI screening into first-visit antenatal care services was feasible and highly acceptable for HIV-infected pregnant women.

Neisseria gonorrhoeae isolates with decreased susceptibility to extended-spectrum cephalosporins (ESCs) are increasing. We developed an assay to predict N. gonorrhoeae susceptibility to ESCs by targeting penA mosaic XXXIV, an allele prevalent among U.S. isolates with elevated ESC MICs. The assay was 97% sensitive and 100% specific for predicting at least one ESC MIC above the CDC alert value among clinical isolates, and it could be multiplexed with a previously validated gyrA PCR to predict ciprofloxacin susceptibility.

Alcohol abuse can influence sexual risk behavior; however, its measurement is not straightforward. This study compared self-reported alcohol use, via the AUDIT and CAGE, with levels of phosphatidylethanol (Peth), a phospholipid biomarker that forms with chronic, heavy drinking, among high-risk MSM and TW in Lima, Peru. Chi square, Fisher's exact, Wilcoxon ranksum tests compared the instruments. Receiver operating curves determined sensitivity and specificity of the self-reported measures. Among 69 MSM and 17 TW, PEth was positive for 86% (95% CI 77-93%) of participants, while 67% reported binge-drinking in the last 2 weeks. The AUDIT classified 25% as hazardous drinkers while CAGE identified 6% as problem drinkers. Self-reported binge drinking was more sensitive than the AUDIT for PEth positivity (71% vs. 27%, p = 0.022). Among high-risk MSM and TW in Lima, validated, self-report measures of alcohol abuse underestimated biological measures. Further research correlating bio-markers and self-reported alcohol abuse measures is needed.

AIM: This study aimed to assess the progression-free and overall survival of patients with residual microscopic disease following neoadjuvant chemoradiotherapy and rectal resection for locally advanced rectal cancer. METHOD: Two-hundred and thirty-four consecutive rectal cancer patients who had neoadjuvant chemoradiotherapy followed by radical resection (from May 2000 to April 2012) were divided according to pathological tumour response: residual microscopic disease (MIC), complete response (pCR) and partial/no response (non-CR). Data on the neoadjuvant regime, treatment-to-surgery interval, final pathology, type of operation, operative time, postoperative complications, length of hospital stay, disease recurrence and mortality were compared between the groups. RESULTS: There were 13 (5.5%) MIC patients, 48 (20.5%) with pCR and 173 (73.9%) with non-CR group. The groups were demographically comparable. MIC patients had more retrieved lymph nodes compared with the non-CR and pCR patients (median 13 compared with 8 and 10, respectively, P = 0.0086). The 5-year overall survival rates were 93.4% for the pCR and MIC patients vs 82.1% for the non-CR patients (P = 0.0324). The 5-year progression-free survival was 85.2% for the pCR and MIC patients vs 73.8% for the non-CR patients (P = 0.086). CONCLUSION: We have identified and assessed a new pathological subgroup of rectal cancer patients who had residual microscopic disease after neoadjuvant therapy. The survival analysis aligned them closely with pCR patients.

In the United States, 19.2% of Neisseria gonorrhoeae isolates are resistant to ciprofloxacin. We evaluated a real-time PCR assay to predict ciprofloxacin susceptibility using residual DNA from the Roche Cobas 4800 CT/NG assay. The results of the assay were 100% concordant with agar dilution susceptibility test results for 100 clinical isolates. Among 76 clinical urine and swab specimens positive for N. gonorrhoeae by the Cobas assay, 71% could be genotyped. The test took 1.5 h to perform, allowing the physician to receive results in time to make informed clinical decisions.

Combining the detection of syphilis and HIV antibodies into one point-of-care test integrates syphilis screening into already existing HIV screening programs, which may be particularly beneficial in settings such as antenatal care. Using the INSTI Multiplex downward-flow immunoassay, we tested 200 stored serum samples from high-risk patients enrolled in a longitudinal study on HIV infection and syphilis in Peruvian men who have sex with men and transgender women. This rapid assay detected HIV and Treponema pallidum serum antibodies with sensitivities of 100% (95% confidence interval [CI], 95.9% to 100%) and 87.4% (95% CI, 81.4% to 92.0%), respectively, and specificities of 95.5% (95% CI, 89.9% to 98.5%) and 97.0% (95% CI, 84.2% to 99.9%), respectively (n = 200). The sensitivity for syphilis antibody detection was higher in patients with a rapid plasma reagin titer of ≥1:8 (97.3%) than in those with a titer of ≤1:4 (90%) or a nonreactive titer (66.7%).

BACKGROUND: Current literature comparing the prevalence rates of curable sexually transmitted infections (STIs) in pregnant women in various global regions is limited. As a result, antenatal screening practices for curable STIs in pregnant women, specifically Treponema pallidum (syphilis), Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), and Trichomonas vaginalis (TV) vary around the world, differing by country and particular STI. METHODS: We conducted a systematic review of publications on STI prevalence among pregnant women in 30 different low- and middle-income countries. We searched PubMed for studies reporting prevalence of syphilis, CT, NG, and TV in pregnant women. English language studies published between January 1, 2010, and March 1, 2015, were included. The adjusted mean STI prevalence by region was calculated via multivariable linear regression adjusting for health care setting, women's mean age, study sample size, and sensitivity of diagnostic test. RESULTS: We identified 75 studies that met inclusion criteria, providing 116 point prevalence estimates for curable STIs among 3,489,621 pregnant women. Adjusted mean prevalence for NG ranged from 1.2% (95% confidence interval [CI], 1.0-1.3) in Latin America to 4.6% (95% CI, 4.0-5.2) in Southern Africa; syphilis prevalence ranged from 1.1% (95% CI, 0.5-1.6) in Asia to 6.5% (95% CI, 4.7-6.3) in Southern Africa; CT ranged from 0.8% (95% CI, 0.4-1.1) in Asia to 11.2% (95% CI, 6.0-16.4) in Latin America; and TV ranged from 3.9% (95% CI, 2.2-5.6) in Latin America to 24.6% (95% CI, 17.9-31.4) in Southern Africa. CONCLUSIONS: Although we observed a wide variation in STI burden in pregnancy after adjusting for age, test, and health care setting, further valid comparison may depend on adjustment for access to care and screening practices.

BACKGROUND: We evaluated the prognostic significance and universal validity of the total number of evaluated lymph nodes (ELN), number of positive lymph nodes (PLN), lymph node ratio (LNR), and log odds of positive lymph nodes (LODDS) in a relatively large and homogenous cohort of surgically treated pancreatic ductal adenocarcinoma (PDAC) patients. METHODS: Prospectively accrued data were retrospectively analyzed for 282 PDAC patients who had pancreaticoduodenectomy (PD) at our institution. Long-term survival was analyzed according to the ELN, PLN, LNR, and LODDS. RESULTS: Of these patients, 168 patients (59.5 %) had LN metastasis (N1). Mean ELN and PLN were 13.5 and 1.6, respectively. LN positivity correlated with a greater number of evaluated lymph nodes; positive lymph nodes were identified in 61.4 % of the patients with ELN ≥ 13 compared with 44.9 % of the patients with ELN < 13 (p = 0.014). Median overall survival (OS) and 5-year OS rate were higher in N0 than in N1 patients, 22.4 vs. 18.7 months and 35 vs. 11 %, respectively (p = 0.008). Mean LNR was 0.12; 91 patients (54.1 %) had LNR < 0.3. Among the N1 patients, median OS was comparable in those with LNR ≥ 0.3 vs. LNR < 0.3 (16.7 vs. 14.1 months, p = 0.950). Neither LODDS nor various ELN and PLN cutoff values provided more discriminative information within the group of N1 patients. CONCLUSIONS: Our data confirms that lymph node positivity strongly reflects PDAC biology and thus patient outcome. While a higher number of evaluated lymph nodes may provide a more accurate nodal staging, it does not have any prognostic value among N1 patients. Similarly, PLN, LNR, and LODDS had limited prognostic relevance.
RESUMO
BACKGROUND: The aim of the present study was to document long-term clinical recurrence and re-resection rates of segmental and extended colectomy in patients with Crohn's colitis and to identify risk factors causing recurrence. METHODS: Records of patients with isolated colonic Crohn's disease who underwent colectomy between 1995 and 2013 and were followed at our medical center were identified. Data on age at diagnosis, gender, smoking, disease location at diagnosis, perianal and rectal disease, indication for surgery, preoperative disease duration, type of operation, primary anastomosis at first operation, length of resected specimen, recurrence of symptoms, postoperative medication, reoperation, and total follow-up time were retrieved. RESULTS: Thirty-five suitable patients (18 segmental colectomy, 17 extensive colectomy; 17 males; mean age at operation 36.6 years) were identified. Mean age at primary operation was 36 years. The mean preoperative disease duration was 121 months. Postoperative medical treatment was needed in 10 (56 %) patients undergoing segmental colectomy and in 16 (94 %) of those undergoing extensive colectomy (p = 0.01). There was longer reoperation-free survival in the segmental colectomy patient group (p = 0.02) and also a trend toward longer symptom-free survival compared to the extensive colectomy patient group (p = 0.105). There was no correlation between the length of resected bowel and recurrence. Patients operated on at a younger age did not have a higher rate of recurrence of symptoms. Shorter disease duration, smoking, and male gender were risk factors for clinical recurrence. CONCLUSIONS: Segmental resection with primary anastomosis can be safely performed in patients with limited Crohn's colitis with reasonable clinical recurrence rates.

Sleep bruxism (SB), primarily involving rhythmic grinding of the teeth during sleep, has been advanced as a causal or maintenance factor for a variety of oro-facial problems, including temporomandibular disorders (TMD). As laboratory polysomnographic (PSG) assessment is extremely expensive and time-consuming, most research testing this belief has relied on patient self-report of SB. The current case-control study examined the accuracy of those self-reports relative to laboratory-based PSG assessment of SB in a large sample of women suffering from chronic myofascial TMD (n = 124) and a demographically matched control group without TMD (n = 46). A clinical research coordinator administered a structured questionnaire to assess self-reported SB. Participants then spent two consecutive nights in a sleep laboratory. Audiovisual and electromyographic data from the second night were scored to assess whether participants met criteria for the presence of 2 or more (2+) rhythmic masticatory muscle activity episodes accompanied by grinding sounds, moderate SB, or severe SB, using previously validated research scoring standards. Contingency tables were constructed to assess positive and negative predictive values, sensitivity and specificity, and 95% confidence intervals surrounding the point estimates. Results showed that self-report significantly predicted 2+ grinding sounds during sleep for TMD cases. However, self-reported SB failed to significantly predict the presence or absence of either moderate or severe SB as assessed by PSG, for both cases and controls. These data show that self-report of tooth grinding awareness is highly unlikely to be a valid indicator of true SB. Studies relying on self-report to assess SB must be viewed with extreme caution.

BACKGROUND: Diverticulitis is a common indication for surgical emergency room admission, often leading to abdominal computed tomography (CT) scanning for both diagnosis and staging. C-reactive protein (CRP) has been identified as a useful biomarker of inflammation. Aspirin and corticosteroids are known to down-regulate CRP production. In this study, we evaluated the usefulness of CRP as a biomarker for complicated diverticulitis and specifically in patients on anti-inflammatory medications: aspirin and corticosteroids. METHODS: We analyzed the medical records of patients diagnosed at one medical center during a two-year period, with left-sided diverticulitis, according to clinical data and CT scan. Disease severity was assessed by the Hinchey score using the radiological findings detected by CT. RESULTS: A total of 295 patients were included in the study. Two hundred and forty-three (82 %) were classified with uncomplicated (Hinchey 1a) and 52 (18 %) with complicated disease (Hinchey > 1a). Mean CRP levels were 133.5 and 63.5 mg/ml for those with complicated and uncomplicated disease, respectively (p < 0.001), and 139 and 60 mg/ml, respectively (p < 0.001) in the subgroup of patients taking aspirin (n = 61). For 14 patients on corticosteroid treatment, the difference in mean CRP levels for complicated and uncomplicated disease was not statistically significant. CRP > 90 mg/ml had 88 % sensitivity and 75 % specificity for complicated disease. CONCLUSIONS: The CRP level distinguished between complicated and uncomplicated disease among left-sided diverticulitis patients including those taking aspirin, but not among those on corticosteroid treatment.

AIM: The effect of restorative proctocolectomy (RPC) on fertility and pregnancy in women with ulcerative colitis (UC) was evaluated. METHOD: Post-RPC female patients with UC who were attempting to become pregnant filled out questionnaires on fertility and pregnancy. Demographic and pouch data of pregnancies ending with delivery were collected from a prospective database. RESULTS: Forty-one women, 44 ± 10 years of age, completed the questionnaires. The median follow-up period post-RPC was 167 (range, 20-352) months. Before RPC, 26 women had 70 pregnancies and 62 deliveries. After RPC, 17 women had 32 pregnancies and 26 deliveries (P = 0.0035). Post-RPC, 10 (37%) of 27 patients failed to conceive compared with 26/26 successful attempts before RPC (P = 0.0006). The number of offspring per patient was 2.38 ± 1.27 before, and 0.68 ± 0.93 after, RPC (P < 0.0001). A higher number of spontaneous pregnancies occurred before (56/62; 90%) than after (15/25; 60%) RPC (P = 0.0004). The time to conception was longer (5.0 ± 11.6 vs 16.3 ± 25.1 months; P = 0.039) and there were more in-vitro fertilization procedures (three vs six) post-RPC. The gestation period was similar, but after RPC more deliveries were by Caesarean section (12.9% vs 46.2%; P = 0.0007). Babies born before RPC weighed more than those born after RPC (3.16 ± 0.61 kg vs 2.79 ± 0.68 kg, respectively; P = 0.0327). CONCLUSION: RPC is associated with an increased risk of infertility, similar duration of gestation and lower birthweight. Female candidates for RPC who have not finished family planning should be counselled accordingly.

Despite theoretical speculation and strong clinical belief, recent research using laboratory polysomnographic (PSG) recording has provided new evidence that frequency of sleep bruxism (SB) masseter muscle events, including grinding or clenching of the teeth during sleep, is not increased for women with chronic myofascial temporomandibular disorder (TMD). The current case-control study compares a large sample of women suffering from chronic myofascial TMD (n = 124) with a demographically matched control group without TMD (n = 46) on sleep background electromyography (EMG) during a laboratory PSG study. Background EMG activity was measured as EMG root mean square (RMS) from the right masseter muscle after lights out. Sleep background EMG activity was defined as EMG RMS remaining after activity attributable to SB, other orofacial activity, other oromotor activity and movement artefacts were removed. Results indicated that median background EMG during these non-SB event periods was significantly higher (P < 0·01) for women with myofascial TMD (median = 3·31 µV and mean = 4·98 µV) than for control women (median = 2·83 µV and mean = 3·88 µV) with median activity in 72% of cases exceeding control activity. Moreover, for TMD cases, background EMG was positively associated and SB event-related EMG was negatively associated with pain intensity ratings (0-10 numerical scale) on post-sleep waking. These data provide the foundation for a new focus on small, but persistent, elevations in sleep EMG activity over the course of the night as a mechanism of pain induction or maintenance.

OBJECTIVE: Genital herpes is a common sexually transmitted disease among young adults in the United States. We conducted a cross-sectional survey to evaluate herpes simplex virus knowledge among university students. PARTICIPANTS: 612 full-time undergraduate students. METHODS: We gathered data on demographics, sexual activity, knowledge about the herpes simplex virus, attitudes toward it, and preferences for testing and treatment. RESULTS: Of 612 full-time undergraduate students, 71.4% (437/612) reported being sexually active. Of them, 54.2% (237/437) reported ever being tested for a sexually transmitted infection. On a standardized knowledge assessment of genital herpes, 22.7% (139/612) of participants scored ≥80% correct. Over half of participants, 57.2% (350/612), reported that they could not cope with a genital herpes outbreak. Being sexually active and tested for sexually transmitted infections was associated with higher scores on the genital herpes knowledge assessment. CONCLUSION: University students have low knowledge regarding genital herpes. Genital herpes education is needed to improve sexual health and wellness.
