Question: Worldwide, each year, large numbers of women are referred for colposcopy following low-grade abnormal cervical cytology. Many have no visible abnormality on examination. The risk of cervical intra-epithelial neoplasia grade 2/3 (CIN2/3) in these women is low. It is unknown whether, for women, a normal colposcopy resolves the anxiety which often follows the receipt of an abnormal cytology result. We investigated the prevalence of adverse psychological outcomes over 30months following a normal colposcopy.', 'This cohort study was nested within the UK TOMBOLA randomized controlled trial. Women aged 20-59years, with recent low-grade cytology, who had a satisfactory colposcopy examination and normal transformation zone, completed the Hospital Anxiety and Depression Scale (HADS) and Process Outcome Specific Measure (POSM) at recruitment and during follow-up (12, 18, 24 and 30months post-recruitment). Outcomes included percentages reporting significant anxiety (HADS anxiety subscale score 11), significant depression (HADS depression subscale score 8) or worries about the result of the next cytology test, cervical cancer, having sex, future fertility and general health at each time point (point prevalence) and during follow-up (cumulative prevalence).', 'The study included 727 women. All psychological measures (except depression) had high prevalence at recruitment, falling substantially by 12months. During follow-up, the cumulative prevalence of significant anxiety was 27% and significant depression was 21%. The most frequently reported worry was that the next cytology test would be abnormal (cumulative prevalence of 71%; point prevalence of 50% at 12 and 18months). The cumulative prevalence values of worries about cervical cancer, having sex and future fertility were 33%, 20% and 16%, respectively.

Question: It is largely unknown how frequently low-abundance HIV drug-resistant variants at levels under limit of detection of conventional genotyping (<20% of quasi-species) are present in antiretroviral-experienced persons experiencing virologic failure. Further, the clinical implications of low-abundance drug-resistant variants at time of virologic failure are unknown.', "Plasma samples from 22 antiretroviral-experienced subjects collected at time of virologic failure (viral load 1380 to 304,000 copies/mL) were obtained from a specimen bank (from 2004-2007). The prevalence and profile of drug-resistant mutations were determined using Sanger sequencing and ultra-deep pyrosequencing. Genotypes were interpreted using Stanford HIV database algorithm. Antiretroviral treatment histories were obtained by chart review and correlated with drug-resistant mutations. Low-abundance drug-resistant mutations were detected in all 22 subjects by deep sequencing and only in 3 subjects by Sanger sequencing. In total they accounted for 90 of 247 mutations (36%) detected by deep sequencing; the majority of these (95%) were not detected by standard genotyping. A mean of 4 additional mutations per subject were detected by deep sequencing (p<0.0001, 95%CI: 2.85-5.53). The additional low-abundance drug-resistant mutations increased a subject's genotypic resistance to one or more antiretrovirals in 17 of 22 subjects (77%). When correlated with subjects' antiretroviral treatment histories, the additional low-abundance drug-resistant mutations correlated with the failing antiretroviral drugs in 21% subjects and correlated with historical antiretroviral use in 79% subjects (OR, 13.73; 95% CI, 2.5-74.3, p = 0.0016).

Question: Adequate visualization of the placenta or umbilical cord during fetoscopic procedures in complicated monochorionic twin pregnancies may be difficult because of placental position and spatial constraints, as well as stained amniotic fluid. Partial amniotic carbon dioxide insufflation (PACI) has made it possible to overcome these obstacles in other fetoscopic procedures, but its value has not yet been reported in monochorionic twins.', 'Partial amniotic carbon dioxide insufflation was carried out in five expectant women with complicated monochorionic twin pregnancies between 19 + 6 to 29 + 4 weeks of gestation when adequate fetoscopic visualization of pathological placental surface vessels or the umbilical cord was impossible because of stained or too little amniotic fluid. In four cases, five fetoscopic laser ablations of pathological placental vessels in twin-to-twin transfusion syndrome (TTTS) were performed. In one discordant twin pregnancy with TTTS, PACI was carried out in order to achieve umbilical cord ligation in a recipient with omphalocele and cardiac malformation.', 'Partial amniotic carbon dioxide insufflation offered superior visualization and did not result in any acute maternal or fetal complications. After fetoscopic laser coagulation, three women delivered one fetus at 27 + 5, two fetuses at 28 + 6, and two fetuses at 35 + 4 weeks of gestation, respectively. One set of twins with TTTS was lost. Following umbilical cord ligation, the surviving twin was delivered at 37 + 2 weeks of gestation.
