Curating duplicates: operationalizing similiarity in the Smithsonian Institution with Haida rattles, 1880-1926.

In the late nineteenth century, the anthropology curators of the Smithsonian Institution consulted their cataloguing systems and storerooms, assessing specimens in order to determine which could be designated as duplicate specimens and exchanged with museums domestically and abroad. The status of 'duplicate' for specimens was contingent on conceptions of similiarity impacted by disciplinary classification praxis, with particular emphasis on object nomenclature and formal attributes. Using rattles from Haida Gwaii collected between 1881 and 1885 by James Swan for the Smithsonian Institution, this article explores how anthropology curators designated rattles as exchangeable duplicate specimens. It considers cataloguing and spatial arrangements, as well as changing populations and formal characteristics of rattles, in order to explore how similarity was operationalized in the museum to produce duplicate anthropological specimens.

Tuberculosis Preventive Treatment Scale-Up Among Antiretroviral Therapy Patients - 16 Countries Supported by the U.S. President's Emergency Plan for AIDS Relief, 2017-2019.

Tuberculosis (TB) is the leading cause of death among persons living with human immunodeficiency virus (HIV) infection. In 2018, an estimated 251,000 persons living with HIV infection died from TB, accounting for one third of all HIV-related deaths and one sixth of all TB deaths (1). TB preventive treatment (TPT) is recommended by the World Health Organization (WHO) for persons living with HIV infection without active TB disease (i.e., adults with a negative clinical symptom screen for cough, fever, night sweats, or weight loss; and children with a negative clinical screen for cough, fever, contact with a person with TB, or poor weight gain) and either without* a tuberculin skin test result or with a known positive result (2). TPT decreases morbidity and mortality among persons living with HIV infection, independent of antiretroviral therapy (ART) (3); however, in 2017, fewer than 1 million of the estimated 21.3 million ART patients started TPT worldwide. Most patients receiving TPT were treated with 6 months of daily isoniazid (1,4). This report summarizes data on TB symptom screening and TPT initiation and completion among ART patients in 16 countries supported by the U.S. President's Emergency Plan for AIDS† Relief (PEPFAR) during April 1, 2017-March 31, 2019. During this period, these 16 countries accounted for approximately 90% of PEPFAR-supported ART patients. During April 1, 2017-September 30, 2018, TB symptom screening increased from 54% to 84%. Overall, nearly 2 million ART patients initiated TPT, and 60% completed treatment during October 1, 2017-March 31, 2019. Although TPT initiations increased substantially, completion among those who initiated TPT increased only from 55% to 66%. In addition to continuing gains in initiation, improving retention after initiation and identifying barriers to TPT completion are important to increase TPT scale-up and reduce global TB mortality.

Ambient air pollution and adverse birth outcomes: a natural experiment study.

BACKGROUND: Radical regulations to improve air quality, including traffic control, were implemented prior to and during the 2008 Beijing Olympic Games. Consequently, ambient concentrations of nitrogen dioxide (NO2) and particular matter 10 micrometers or less (PM10), were reduced in a distinct and short window of time, which presented a natural experiment for testing the relationships between maternal exposure to PM10 and NO2 during pregnancy and adverse birth outcomes. METHODS: We estimated the effect of PM10 and NO2 exposure during each trimester of gestation on the risk of preterm birth among live births and the birth weight among term babies. The data were based on 50,874 live births delivered between January 1, 2006 and December 31, 2010 at the Beijing Haidian Maternal and Child Health Hospital. Air monitoring data for the same period were obtained from the Beijing Municipal Environmental Monitoring Center. RESULTS: Among full-term births, maternal exposure to NO2 in the third trimester predicted birth weight, with each 10-unit increment (per 10 ug/m(3)) in NO2 concentration associated with a 13.78 g (95 % confidence interval: -21.12, -6.43; p < 0.0001) reduction in birth weight. This association was maintained after adjusting for other pollutants, including carbon monoxide (CO), sulfur dioxide (SO2), and PM10. No relationship was found between the concentration of PM10 and low birth weight among full-term births. Neither PM10 nor NO2 concentrations predicted the risk of premature birth. CONCLUSIONS: Exposure to ambient air pollution during certain periods of pregnancy may decrease birth weight, but the effect size is small.

Parameters for sample size estimation from a group-randomized HIV prevention trial in HIV clinics in sub-Saharan Africa.

Sample size calculations for a group-randomized trial (GRT) require an estimate of the expected intraclass correlation coefficient (ICC). However, few ICC estimates from GRTs in HIV/AIDS research have been published, leaving investigators with little data on which to base expectations. We used data from a multi-country study to estimate ICCs for variables related to physical and mental health and HIV risk behaviors. ICCs for perceptions of physical and mental health tended to be higher than those for HIV risk behavior variables, which were higher than ICCs for CD4 count. Covariate adjustment for country and socio-demographic variables reduced most ICC estimates. For risk behavior variables, adjustment for country and socio-demographic variables reduced ICC estimates by as much as 84 %. Variability in ICC estimates has important implications for study design, as a larger ICC reduces power. ICC estimates presented in this analysis will allow more precise sample size estimates for future GRTs.

Exploring early and future use of DNP prepared nurses within healthcare organizations.

A strategy to gather data on DNP utilization and impact was designed using Donabedian's conceptual model and was piloted by surveying chief nursing officers (CNOs) leading Michigan's public and teaching hospital systems. Few of the responding CNOs reported currently employing DNP-prepared nurses. The majority reported gaps in knowledge related to role expectations and projected outcomes from a DNP-prepared nurse. Nurse leaders should become familiar with the role competencies of the DNP in order to maximize the potential contribution of this new level of care provider to improving care quality and access.

Patterns of Pediatric Palliative and End-of-Life Care in Neonatal Intensive Care Patients in the Southern U.S.

CONTEXT: Despite high rates of mortality among infants in the Southern U.S., little is known about the timing of pediatric palliative care (PPC), the intensity of end-of-life care, and whether there are differences among sociodemographic characteristics. OBJECTIVES: To describe PPC patterns and treatment intensity during the last 48 hours of life among neonatal intensive care unit (NICU) patients in the Southern U.S. who received specialized PPC. METHODS: Medical record abstraction of infant decedents who received PPC consultation in two NICUs (in Alabama and Mississippi) from 2009 to 2017 (n = 195) including clinical characteristics, palliative and end-of-life care characteristics, patterns of PPC, and intensive medical treatments in the last 48 hours of life. RESULTS: The sample was racially (48.2% Black) and geographically (35.4% rural) diverse. Most infants died after withdrawal of life-sustaining interventions (58%) and had do not attempt resuscitation orders documented (75.9%); very few infants enrolled in hospice (6.2%). Initial PPC consult occurred a median of 13 days after admission and a median of 17 days before death. Infants with a primary diagnosis of genetic or congenital anomaly received earlier PPC consultation (P = 0.02) compared to other diagnoses. In the last 48 hours of life, NICU patients received intensive interventions including mechanical ventilation (81.5%), CPR (27.7%) and surgeries or invasive procedures (25.1%). Black infants were more likely to receive CPR compared to White infants (P = 0.04). CONCLUSION: Overall, PPC consultation occurred late in NICU hospitalizations, infants received high-intensity medical interventions in the last 48 hours of life, and there are disparities in intensity of treatment interventions at end of life. Further research is needed to explore if these patterns of care reflect parent preferences and goal concordance.

Collect Once, Use Many Times: Attaining Unified Metrics for Tuberculosis Preventive Treatment for People Living With HIV.

The World Health Organization (WHO) recommends providing tuberculosis preventive treatment (TPT) to all persons living with HIV and to all household contacts of persons with bacteriologically confirmed pulmonary tuberculosis disease. Regrettably, the absence of a harmonized data collection and management approach to TPT indicators has contributed to programmatic challenges at local, national, and global levels. However, in April 2020, the WHO launched the Consolidated HIV Strategic Information Guidelines, with an updated set of priority indicators. These guidelines recommend that Ministries of Health collect, report, and use data on TPT completion in addition to TPT initiation. Both indicators are reflected in the WHO's list of 15 core indicators for program management and are also required by the US President's Emergency Plan for AIDS Relief's Monitoring, Evaluation, and Reporting (MER) guidance. Although not perfectly harmonized, both frameworks now share essential indicator characteristics. Aligned indicators are necessary for robust strategic and operational planning, resource allocation, and data communication. "Collect once, use many times" is a best practice for strategic information management. Building harmonized and sustainable health systems will enable countries to successfully maintain essential HIV, tuberculosis, and other health services while combatting new health threats.

Anal sphincter defects and bowel symptoms in women with and without recognized anal sphincter trauma.

OBJECTIVE: The purpose of this study was to determine the rate of new bowel symptoms and anal sphincter defects in primiparous women with and without recognized anal sphincter (AS) injury. STUDY DESIGN: One hundred seventeen primiparous women classified with increasing degrees of perineal trauma and 21 controls delivered by cesarean section were enrolled immediately postpartum and demographic and delivery data were collected. At 6 weeks' postpartum, subjects completed a bowel function questionnaire and endoanal ultrasonography was performed. Logistic regression, chi-square, and 2-sample t tests were used for statistical analysis. RESULTS: A significant difference in new bowel symptoms was reported in women with (39%) and without (11%) recognized AS injury (P = .002). AS defects were present in 0%, 15%, 23%, 37%, and 67% of women with C/S, first-, second-, third-, and fourth-degree lacerations, respectively. Combined defects of the internal and external AS were associated with the greatest risk of new bowel symptoms (OR 32.1 [95% CI 9.6-107], P < .001). CONCLUSION: In women with and without recognized AS trauma, new bowel symptoms were strongly correlated with the presence of anatomic AS defects postpartum.

Anal incontinence in women with and those without pelvic floor disorders.

OBJECTIVE: To compare the prevalence of anal incontinence and anal sphincter injury in women with pelvic floor disorders (cases) with those in a group of normal control subjects and to evaluate the relationship between sphincter injury and anal incontinence in each group. METHODS: We previously reported the results of a cross-sectional study of 100 women with pelvic floor disorders (> or = stage II pelvic organ prolapse and/or urinary incontinence). In this study, we compared those cases with 90 controls (stage 0 or I pelvic organ prolapse and no urinary incontinence) who completed the Rockwood-Thompson fecal incontinence severity index, in which scoring (0-61) is based on the frequency and type of anal incontinence. All women underwent endoanal ultrasonography, and the internal and external anal sphincters were reported as intact versus disrupted. Chi-square test, Student t test, and logistic regression were used for statistical analysis. RESULTS: Women with pelvic floor disorders were significantly more likely to report anal incontinence (54% versus 17.8%, odds ratio [OR] 5.4, 95% confidence interval [CI] 2.8-10.6, P < .001) and had higher mean fecal incontinence severity index scores (22.3 +/- 13 versus 12.7 +/- 6.3, P = .006) than controls. Cases demonstrated higher rates of anal sphincter defects on ultrasound examination than did controls (52% versus 30%, P = .007). Anal incontinence was significantly associated with anal sphincter injury in women with pelvic floor disorders (OR 36.4, 95% CI 12-114, P < .001) and in controls (OR 5.9, 95% CI 3-11, P = .002). CONCLUSION: Anal incontinence was more common in women with pelvic floor disorders than normal controls and may be due to higher rates of anatomic anal sphincter disruption in this group.

Thermal balloon endometrial ablation for management of acute uterine hemorrhage.

BACKGROUND: Life-threatening abnormal uterine bleeding can be managed by a variety of techniques, which include intravenous estrogen, dilation and curettage, endometrial ablation, uterine artery embolization, or hysterectomy. Thermal balloon endometrial ablation has been used in the management of chronic dysfunctional uterine bleeding but has not been described in a case of acute uterine hemorrhage. CASE: A 44-year-old woman with end-stage liver disease presented with vaginal bleeding and fever. She was found to have sepsis, coagulopathy, and anemia. No anatomic uterine pathology was identified. Antibiotics, intravenous estrogen, and blood products were administered, but heavy bleeding persisted. Thermal balloon ablation resulted in abrupt cessation of uterine bleeding. CONCLUSION: Thermal balloon ablation appears to be an effective method for management of acute uterine hemorrhage.

Anal sphincter injury in women with pelvic floor disorders.

OBJECTIVE: 1) To estimate the rate of anal incontinence and anal sphincter injury in a group of women with pelvic floor disorders; 2) to evaluate the relationship between anal incontinence and anal sphincter injury as demonstrated by endoanal ultrasonography; 3) to explore any associations between operative vaginal delivery and anal sphincter injury in this population. METHODS: A cohort of 100 women with stage II or greater pelvic organ prolapse and/or urinary incontinence completed the Rockwood-Thompson Fecal Incontinence Severity Index Questionnaire (FISI). Pelvic organ prolapse was recorded using the Pelvic Organ Prolapse Quantification system. Multichannel cystometry and endoanal ultrasonography were performed. Categorical data were compared using the chi(2) statistic. The FISI scores were correlated with degree of anal sphincter injury using the Pearson correlation coefficient (r). RESULTS: Fifteen women with pelvic organ prolapse only, 28 with urinary incontinence only, and 57 with both were evaluated. Mean age (+/- standard deviation) and body mass index were 57.1 +/- 13.2 years and 29.8 +/- 6.8 kg/m(2), respectively. Median parity was 3. Fifty-four percent of those studied had anal incontinence, and 52% had anal sphincter defects. Anal incontinence was significantly associated with sphincter injury (odds ratio 36.4, 95% confidence interval 12-114, P <.001). The FISI scores were positively correlated with increasing degrees of anal sphincter disruption (r = 0.81, P <.001). A history of operative vaginal delivery was significantly associated with anal sphincter injury (P =.023). CONCLUSION: Anal incontinence and anal sphincter injury are common in women with other pelvic floor disorders and are significantly related. Operative vaginal delivery may contribute to unrecognized anal sphincter trauma in this population. LEVEL OF EVIDENCE: III

Elevated levels of protein in urine in adulthood after exposure to the Chinese famine of 1959-61 during gestation and the early postnatal period.

BACKGROUND: Animal models have suggested that undernutrition during gestation and the early postnatal period may adversely affect kidney development and compromise renal function. As a natural experiment, famines provide an opportunity to test such potential effects in humans. We assessed whether exposure to the Chinese famine of 1959-1961 during gestation and early postnatal life was associated with the levels of proteinuria among female adults three decades after exposure to the famine. METHODS: We measured famine intensity using the cohort size shrinkage index and we constructed a difference-in-difference model to compare the levels of proteinuria, measured with a dipstick test of random urine specimens, among Chinese women (n = 70 543) whose exposure status to the famine varied across birth cohorts (born before, during or after the famine) and counties of residence with different degrees of famine intensity. RESULTS: Famine exposure was associated with a greater risk [odds ratio (OR) = 1.54; 95% confidence interval (CI): 1.04, 2.28; P = 0.029) of having higher level of proteinuria among women born during the famine years (1959-61) compared with the unexposed post famine-born cohort (1964-65) in rural samples. No association was observed among urban samples. Results were robust to adjustment for covariates. CONCLUSIONS: Severe undernutrition during gestation and the early postnatal period may have long-term effects on levels of proteinuria in humans, but the effect sizes may be small.

Chart documentation of informed consent for operative vaginal delivery: is it adequate?

OBJECTIVES: To determine the documentation frequency of informed consent for women undergoing a trial of nonemergent instrumental delivery. STUDY DESIGN: A retrospective chart review of instrumented vaginal deliveries from 1992 to 2005 was performed. Cases were identified from a Labor and Delivery database and hospital records were reviewed for documentation of associated risks, general consent for the procedure, indication, and option of cesarean delivery (CD). RESULTS: Three hundred forty six charts were reviewed: 246 were excluded for an emergency delivery (19%), misclassification (25%), or lost notes (27%). In the remaining 100 cases, 61% had a general consent for instrumented vaginal delivery. Documentation of any maternal or neonatal risks was found in 3% and 0%, respectively. The option of a cesarean delivery was documented in 22% of the cases. When comparing 5-year time intervals before and after 2000, there was no increased frequency in documentation of maternal or neonatal risks. CONCLUSIONS: Documentation of informed consent for instrumented vaginal delivery is inconsistent and should be improved.

An evaluation of bariatric Web sites for patient education and guidance.

Bariatric surgery for the treatment of obesity has become a trend, with television and music celebrities touting it as a cure. There has been an extraordinary growth rate in the number of people each year undergoing bariatric surgery, and many of these patients are obtaining their information about the surgery from the Internet. As more and more people turn to the Internet for healthcare information, the need to monitor those Web sites for accuracy and quality expands. The purpose of this study was to assess bariatric Web sites for their quality and accuracy of information. Forty Web sites were evaluated using the Health Information Technology Institute (HITI) criteria and five evaluation criteria based on guidelines from the National Institutes of Health (NIH); the readability of the sites also was determined. Web sites were identified for the purpose of patient education and guidance about this explosive topic.

Differences in outcomes after third- versus fourth-degree perineal laceration repair: a prospective study.

OBJECTIVE: The purpose of this study was to compare outcomes after third- versus fourth-degree laceration repair. STUDY DESIGN: Fifty-six primiparous women who sustained a third- or fourth-degree tear were enrolled at delivery and demographic and obstetric data were collected. At 6 weeks' postpartum, subjects completed a bowel function questionnaire and endoanal ultrasonography was performed. Fisher exact test and chi-square were used for statistical analysis. RESULTS: Thirty-nine women with third- and 17 with fourth-degree tears were enrolled. Subjects with fourth- were more likely to report bowel symptoms (59% vs 28%, P = .03), and to demonstrate persistent combined defects of the internal (IAS) and external anal sphincter (EAS) (48% vs 8%, P = .002) than third-degree tears. Combined defects were associated with the highest risk of bowel symptoms (OR 18.7, 95% CI 3-101, P < .001). CONCLUSION: Bowel symptoms were more common after fourth- than third-degree repair, and may be secondary to higher rates of combined defects of the IAS and EAS.
