Distribution of Human Papillomavirus Genotypes among HIV-Positive and HIV-Negative Women in Cape Town, South Africa
Objective: HIV-positive women are known to be at high-risk of human papillomavirus (HPV) infection and its associated cervical pathology. Here, we describe the prevalence and distribution of HPV genotypes among HIV-positive and -negative women in South Africa, with and without cervical intraepithelial neoplasia (CIN). Methods: We report data on 1,371 HIV-positive women and 8,050 HIV-negative women, aged 17–65 years, recruited into three sequential studies in Cape Town, South Africa, conducted among women who had no history of cervical cancer screening recruited from the general population. All women were tested for HIV. Cervical samples were tested for high-risk HPV DNA (Hybrid Capture 2) with positive samples tested to determine the specific genotype (Line Blot). CIN status was determined based on colposcopy and biopsy. Results: The HPV prevalence was higher among HIV-positive women (52.4%) than among HIV-negative women (20.8%) overall and in all age groups. Younger women, aged 17–19 years, had the highest HPV prevalence regardless of HIV status. HIV-positive women were more likely to have CIN 2 or 3 than HIV-negative women. HPV 16, 35, and 58 were the most common high-risk HPV types with no major differences in the type distribution by HIV status. HPV 18 was more common in older HIV-positive women (40–65 years) with no or low grade disease, but less common in younger women (17–29 years) with CIN 2 or 3 compared to HIV-negative counterparts (p < 0.03). Infections with multiple high-risk HPV types were more common in HIV-positive than HIV-negative women, controlling for age and cervical disease status. Conclusion: HIV-positive women were more likely to have high-risk HPV than HIV-negative women; but, among those with HPV, the distribution of HPV types was similar by HIV status. Screening strategies incorporating HPV genotyping and vaccination should be effective in preventing cervical cancer in both HIV-positive and -negative women living in sub-Saharan Africa
Case Report Buttock Necrosis after Uterine Artery Embolization for Delayed Hysterectomy in Placenta Percreta
Background. Morbidly adherent placenta (MAP) is increasing in incidence and is commonly associated with maternal hemorrhage and cesarean hysterectomy. Uterine artery embolization (UAE) may be utilized in the conservative management of placenta percreta to potentially reduce blood loss. The incidence of complications from UAE in the conservative management of placenta percreta is poorly described. To our knowledge, we present the first reported case of buttock necrosis in this setting. Case. A 39-year-old gravida nine para two with placenta percreta who underwent conservative management with UAE complicated by right buttock necrosis. Conclusion. While UAE may potentially decrease blood loss, it is not without risk. More studies must be performed in order to quantify those risks and determine the clinical utility of UAE
Titles versus titles and abstracts for initial screening of articles for systematic reviews
PMC3933432BACKGROUND:
There is no consensus on whether screening titles alone or titles and abstracts together is the preferable strategy for inclusion of articles in a systematic review.
METHODS:
TWO METHODS OF SCREENING ARTICLES FOR INCLUSION IN A SYSTEMATIC REVIEW WERE COMPARED: titles first versus titles and abstracts simultaneously. Each citation found in MEDLINE or Embase was reviewed by two physician reviewers for prespecified criteria: the citation included (1) primary data; (2) the exposure of interest; and (3) the outcome of interest.
RESULTS:
There were 2965 unique citations. The titles first strategy resulted in an immediate rejection of 2558 (86%) of the records after reading the title alone, requiring review of 239 titles and abstracts, and subsequently 176 full text articles. The simultaneous titles and abstracts review led to rejection of 2782 citations (94%) and review of 183 full text articles. Interreviewer agreement to include an article for full text review using the titles-first screening strategy was 89%-94% (kappa = 0.54) and 96%-97% (kappa = 0.56) for titles and abstracts combined. The final systematic review included 13 articles, all of which were identified by both screening strategies (yield 100%, burden 114%). Precision was higher in the titles and abstracts method (7.1% versus 3.2%) but recall was the same (100% versus 100%), leading to a higher F-measure for the titles and abstracts approach (0.1327 versus 0.0619).
CONCLUSION:
Screening via a titles-first approach may be more efficient than screening titles and abstracts together.JH Libraries Open Access Fun

Human Connection: Oncologist Characteristics and Behaviors Associated With Therapeutic Bonding With Latino Patients With Advanced Cancer
PURPOSETherapeutic alliances (TAs) between oncologists and patients are bonds characterized by mutual caring, trust, and respect. We here relate oncologist characteristics and behaviors to TA among Latino and non-Latino patients with advanced cancer.METHODSParticipants included non-Latino oncologists (n = 41) and their Latino (n = 67) and non-Latino White (n = 90) patients with advanced cancer who participated in Coping with Cancer III, a multisite, US-based prospective cohort study of Latino/non-Latino disparities in end-of-life cancer care, conducted 2015-2019. Oncologist characteristics included age, sex, race, institution type, Spanish language proficiency, familismo practice style (emphasis on family) and clinical etiquette behaviors. Patient-reported TA was assessed using the average score of six items from The Human Connection scale. Hierarchical linear modeling (HLM) estimated effects of oncologist characteristics on TA.RESULTSOf 157 patients, a majority were female (n = 92, 58.6%) and age younger than 65 years (n = 95, 60.5%). Most oncologists were male (n = 24, 58.5%), non-Latino White (n = 25, 61%), and age 40 years and older (n = 25, 61%). An adjusted HLM in the full sample showed that Latino patient ethnicity was associated with significantly lower TA (β = -.25; P < .001). In an adjusted stratified HLM for TA, among Latino patients, oncologist familismo practice style (β = .19; P = .012), preference using first names (β = .25; P = .023), and greater Spanish fluency (β = .11; P < .001) were positively associated with TA. In contrast, familismo practice style had no impact on TA for non-Latino White patients.CONCLUSIONLatino patients with advanced cancer had worse TAs with their oncologists versus non-Latino patients. Modifiable oncologist behaviors may be targeted in an intervention designed to improve the patient-physician relationship between oncologists and their Latino patients with advanced cancer

Robotically assisted delayed total laparoscopic hysterectomy for placenta percreta
Background: The prevalence of morbidly adherent placenta has dramatically increased in the setting of the rising cesarean rate in the United States. Delayed surgical management of placenta accreta and its variants is emerging as methods that may significantly decrease bleeding and perioperative complications; however, optimal surgical approaches have not yet been determined. In this report, we present a case of robotic-assisted delayed interval hysterectomy in a patient with placenta percreta.
Method: A minimally invasive approach, via a robotic-assisted total laparoscopic hysterectomy, was utilized for a 39-year-old gravida 9 para 3 with placenta percreta with placenta left in situ ten weeks after a tertiary cesarean section.
Experience: The robotic approach provided excellent visualization to facilitate fine planes of dissection, lower than expected estimated blood loss, and faster recover times when compared with conventional surgical approaches traditionally utilized for interval hysterectomies for placenta percreta.
Conclusion: Robotic-assisted hysterectomy may be considered as an alternative to laparotomy for the delayed interval surgical management of morbidly adherent placenta percreta

Factors Predicting Use of Neoadjuvant Chemotherapy Compared With Primary Debulking Surgery in Advanced Stage Ovarian Cancer-A National Cancer Database Study.
ObjectivesWe performed a patterns-of-care study to characterize the types of patients with epithelial ovarian cancer (EOC) who received neoadjuvant chemotherapy (NACT) versus primary debulking surgery (PDS) using the National Cancer Database (NCDB).MethodsWe identified patients with stages IIIC and IV EOC in the NCDB diagnosed from 2003 to 2011. Patients who received chemotherapy (CT) prior to surgery were classified as receiving NACT; if surgery preceded CT, then it was classified as PDS. Data collected from the NCDB included demographics, medical comorbidity index, cancer characteristics and treatment, and hospital characteristics. Univariate and multivariable analyses were performed using χ test, logistic regression, log-rank test, and Cox proportional hazards modeling as indicated. Statistical significance was set at P < 0.05.ResultsA total of 62,727 patients with stages IIIC and IV EOC were identified. The sequence of surgery and CT was identified, of which 6922 (11%) had NACT and 31,280 (50%) had PDS. Neoadjuvant CT was more frequently done in stage IV than stage IIIC (13% vs 9%), and its use markedly increased over time. Variables associated with increased likelihood of NACT use were as follows: age older than 50 years and those with higher comorbidities, stage IV, and higher-grade EOC. Neoadjuvant CT use was also associated with hospitals that were adherent to the National Comprehensive Cancer Network guidelines, high-volume facilities, those in the Midwest and West, and academic centers.ConclusionsEvidence suggests that patients with greater adverse risk factors are more likely to receive NACT instead of PDS. Use of NACT has significantly increased over the study period, especially in patients with stage IV ovarian cancer
