NEJM Evid 2024 3 (5) EVIDoa2300342 BACKGROUND: Detection and containment of hospital outbreaks currently depend on variable and personnel-intensive surveillance methods. Whether automated statistical surveillance for outbreaks of health care-associated pathogens allows earlier containment efforts that would reduce the size of outbreaks is unknown. METHODS: We conducted a cluster-randomized trial in 82 community hospitals within a larger health care system. All hospitals followed an outbreak response protocol when outbreaks were detected by their infection prevention programs. Half of the hospitals additionally used statistical surveillance of microbiology data, which alerted infection prevention programs to outbreaks. Statistical surveillance was also applied to microbiology data from control hospitals without alerting their infection prevention programs. The primary outcome was the number of additional cases occurring after outbreak detection. Analyses assessed differences between the intervention period (July 2019 to January 2022) versus baseline period (February 2017 to January 2019) between randomized groups. A post hoc analysis separately assessed pre-coronavirus disease 2019 (Covid-19) and Covid-19 pandemic intervention periods. RESULTS: Real-time alerts did not significantly reduce the number of additional outbreak cases (intervention period versus baseline: statistical surveillance relative rate [RR]=1.41, control RR=1.81; difference-in-differences, 0.78; 95% confidence interval [CI], 0.40 to 1.52; P=0.46). Comparing only the prepandemic intervention with baseline periods, the statistical outbreak surveillance group was associated with a 64.1% reduction in additional cases (statistical surveillance RR=0.78, control RR=2.19; difference-in-differences, 0.36; 95% CI, 0.13 to 0.99). There was no similarly observed association between the pandemic versus baseline periods (statistical surveillance RR=1.56, control RR=1.66; difference-in-differences, 0.94; 95% CI, 0.46 to 1.92). CONCLUSIONS: Automated detection of hospital outbreaks using statistical surveillance did not reduce overall outbreak size in the context of an ongoing pandemic.

Population-based study of rare epilepsy incidence in a US urban population
Barbour K , Tian N , Yozawitz EG , Wolf S , McGoldrick PE , Sands TT , Nelson A , Basma N , Grinspan ZM . Epilepsia 2024 OBJECTIVE: This study was undertaken to estimate incidence of rare epilepsies and compare with literature. METHODS: We used electronic health record text search to identify children with 28 rare epilepsies in New York City (2010-2014). We estimated cumulative incidence and compared with literature. RESULTS: Eight of 28 rare epilepsies had five or more prior estimates, and our measurements were within the published range for all. The most common were infantile epileptic spasms syndrome (1 in 2920 live births), Lennox-Gastaut syndrome (1 in 9690), and seizures associated with tuberous sclerosis complex (1 in 14 300). Fifteen of 28 had fewer than five prior estimates, and of these, we provided additional estimates for early infantile developmental and epileptic encephalopathy (1 in 32 700), epilepsy with myoclonic-atonic seizures (1 in 34 100), Sturge-Weber syndrome plus seizures/epilepsy (1 in 40 900), epilepsy in infancy with migrating focal seizures (1 in 54 500), Aicardi syndrome plus seizures/epilepsy (1 in 71 600), hypothalamic hamartoma with seizures (1 in 225 000), and Rasmussen syndrome (1 in 450 000). Five of 28 rare epilepsies had no prior estimates, and of these, we provided a new estimate for developmental/epileptic encephalopathy with spike-and-wave activation in sleep and/or continuous spikes and waves during sleep (1 in 34 100). Data were limited for the remaining 12 rare epilepsies, which were all genetic epilepsies, including PCDH19, CDKL5, Alpers disease, SCN8A, KCNQ2, SCN2A, GLUT1 deficiency, Phelan-McDermid syndrome, myoclonic epilepsy with ragged-red fibers, dup15q syndrome, ring chromosome 14, and ring chromosome 20. SIGNIFICANCE: We estimated the incidence of rare epilepsies using population-based electronic health record data and literature review. More research is needed to better estimate the incidence of genetic epilepsies with nonspecific clinical features. Electronic health records may be a valuable data source for studying rare epilepsies and other rare diseases, particularly as genetic testing becomes more widely adopted. |
Semi-automated nonresponse detection for open-text survey data
Cibelli Hibben K , Smith Z , Rogers B , Ryan V , Scanlon P , Hoppe T . Soc Sci Comput Rev 2024 Open-ended survey questions can enable researchers to gain insights beyond more commonly used closed-ended question formats by allowing respondents an opportunity to provide information with few constraints and in their own words. Open-ended web probes are also increasingly used to inform the design and evaluation of survey questions. However, open-ended questions are more susceptible to insufficient or irrelevant responses that can be burdensome and time-consuming to identify and remove manually, often resulting in underuse of open-ended questions and, when used, potential inclusion of poor-quality data. To address these challenges, we developed and publicly released the Semi-Automated Nonresponse Detection for Survey text (SANDS), an item nonresponse detection approach based on a Bidirectional Transformer for Language Understanding model, fine-tuned using Simple Contrastive Sentence Embedding and targeted human coding, to categorize open-ended text data as valid or likely nonresponse. This approach is powerful in that it uses natural language processing as opposed to existing nonresponse detection approaches that have relied exclusively on rules or regular expressions or used bag-of-words approaches that tend to perform less well on short pieces of text, typos, or uncommon words, often prevalent in open-text survey data. This paper presents the development of SANDS and a quantitative evaluation of its performance and potential bias using open-text responses from a series of web probes as case studies. Overall, the SANDS model performed well in identifying a dataset of likely valid results to be used for quantitative or qualitative analysis, particularly on health-related data. Developed for generalizable use and accessible to others, the SANDS model can greatly improve the efficiency of identifying inadequate and irrelevant open-text responses, offering expanded opportunities for the use of open-text data to inform question design and improve survey data quality. © The Author(s) 2024. |

Gohil SK , Septimus E , Kleinman K , Varma N , Avery TR , Heim L , Rahm R , Cooper WS , Cooper M , McLean LE , Nickolay NG , Weinstein RA , Burgess LH , Coady MH , Rosen E , Sljivo S , Sands KE , Moody J , Vigeant J , Rashid S , Gilbert RF , Smith KN , Carver B , Poland RE , Hickok J , Sturdevant SG , Calderwood MS , Weiland A , Kubiak DW , Reddy S , Neuhauser MM , Srinivasan A , Jernigan JA , Hayden MK , Gowda A , Eibensteiner K , Wolf R , Perlin JB , Platt R , Huang SS . Jama 2024 IMPORTANCE: Pneumonia is the most common infection requiring hospitalization and is a major reason for overuse of extended-spectrum antibiotics. Despite low risk of multidrug-resistant organism (MDRO) infection, clinical uncertainty often drives initial antibiotic selection. Strategies to limit empiric antibiotic overuse for patients with pneumonia are needed. OBJECTIVE: To evaluate whether computerized provider order entry (CPOE) prompts providing patient- and pathogen-specific MDRO infection risk estimates could reduce empiric extended-spectrum antibiotics for non-critically ill patients admitted with pneumonia. DESIGN, SETTING, AND PARTICIPANTS: Cluster-randomized trial in 59 US community hospitals comparing the effect of a CPOE stewardship bundle (education, feedback, and real-time MDRO risk-based CPOE prompts; n = 29 hospitals) vs routine stewardship (n = 30 hospitals) on antibiotic selection during the first 3 hospital days (empiric period) in non-critically ill adults (≥18 years) hospitalized with pneumonia. There was an 18-month baseline period from April 1, 2017, to September 30, 2018, and a 15-month intervention period from April 1, 2019, to June 30, 2020. INTERVENTION: CPOE prompts recommending standard-spectrum antibiotics in patients ordered to receive extended-spectrum antibiotics during the empiric period who have low estimated absolute risk (<10%) of MDRO pneumonia, coupled with feedback and education. MAIN OUTCOMES AND MEASURES: The primary outcome was empiric (first 3 days of hospitalization) extended-spectrum antibiotic days of therapy. Secondary outcomes included empiric vancomycin and antipseudomonal days of therapy and safety outcomes included days to intensive care unit (ICU) transfer and hospital length of stay. Outcomes compared differences between baseline and intervention periods across strategies. RESULTS: Among 59 hospitals with 96 451 (51 671 in the baseline period and 44 780 in the intervention period) adult patients admitted with pneumonia, the mean (SD) age of patients was 68.1 (17.0) years, 48.1% were men, and the median (IQR) Elixhauser comorbidity count was 4 (2-6). Compared with routine stewardship, the group using CPOE prompts had a 28.4% reduction in empiric extended-spectrum days of therapy (rate ratio, 0.72 [95% CI, 0.66-0.78]; P < .001). Safety outcomes of mean days to ICU transfer (6.5 vs 7.1 days) and hospital length of stay (6.8 vs 7.1 days) did not differ significantly between the routine and CPOE intervention groups. CONCLUSIONS AND RELEVANCE: Empiric extended-spectrum antibiotic use was significantly lower among adults admitted with pneumonia to non-ICU settings in hospitals using education, feedback, and CPOE prompts recommending standard-spectrum antibiotics for patients at low risk of MDRO infection, compared with routine stewardship practices. Hospital length of stay and days to ICU transfer were unchanged. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03697070. |
Stewardship prompts to improve antibiotic selection for urinary tract infection: The INSPIRE Randomized Clinical Trial
Gohil SK , Septimus E , Kleinman K , Varma N , Avery TR , Heim L , Rahm R , Cooper WS , Cooper M , McLean LE , Nickolay NG , Weinstein RA , Burgess LH , Coady MH , Rosen E , Sljivo S , Sands KE , Moody J , Vigeant J , Rashid S , Gilbert RF , Smith KN , Carver B , Poland RE , Hickok J , Sturdevant SG , Calderwood MS , Weiland A , Kubiak DW , Reddy S , Neuhauser MM , Srinivasan A , Jernigan JA , Hayden MK , Gowda A , Eibensteiner K , Wolf R , Perlin JB , Platt R , Huang SS . Jama 2024 IMPORTANCE: Urinary tract infection (UTI) is the second most common infection leading to hospitalization and is often associated with gram-negative multidrug-resistant organisms (MDROs). Clinicians overuse extended-spectrum antibiotics although most patients are at low risk for MDRO infection. Safe strategies to limit overuse of empiric antibiotics are needed. OBJECTIVE: To evaluate whether computerized provider order entry (CPOE) prompts providing patient- and pathogen-specific MDRO risk estimates could reduce use of empiric extended-spectrum antibiotics for treatment of UTI. DESIGN, SETTING, AND PARTICIPANTS: Cluster-randomized trial in 59 US community hospitals comparing the effect of a CPOE stewardship bundle (education, feedback, and real-time and risk-based CPOE prompts; 29 hospitals) vs routine stewardship (n = 30 hospitals) on antibiotic selection during the first 3 hospital days (empiric period) in noncritically ill adults (≥18 years) hospitalized with UTI with an 18-month baseline (April 1, 2017-September 30, 2018) and 15-month intervention period (April 1, 2019-June 30, 2020). INTERVENTIONS: CPOE prompts recommending empiric standard-spectrum antibiotics in patients ordered to receive extended-spectrum antibiotics who have low estimated absolute risk (<10%) of MDRO UTI, coupled with feedback and education. MAIN OUTCOMES AND MEASURES: The primary outcome was empiric (first 3 days of hospitalization) extended-spectrum antibiotic days of therapy. Secondary outcomes included empiric vancomycin and antipseudomonal days of therapy. Safety outcomes included days to intensive care unit (ICU) transfer and hospital length of stay. Outcomes were assessed using generalized linear mixed-effect models to assess differences between the baseline and intervention periods. RESULTS: Among 127 403 adult patients (71 991 baseline and 55 412 intervention period) admitted with UTI in 59 hospitals, the mean (SD) age was 69.4 (17.9) years, 30.5% were male, and the median Elixhauser Comorbidity Index count was 4 (IQR, 2-5). Compared with routine stewardship, the group using CPOE prompts had a 17.4% (95% CI, 11.2%-23.2%) reduction in empiric extended-spectrum days of therapy (rate ratio, 0.83 [95% CI, 0.77-0.89]; P < .001). The safety outcomes of mean days to ICU transfer (6.6 vs 7.0 days) and hospital length of stay (6.3 vs 6.5 days) did not differ significantly between the routine and intervention groups, respectively. CONCLUSIONS AND RELEVANCE: Compared with routine stewardship, CPOE prompts providing real-time recommendations for standard-spectrum antibiotics for patients with low MDRO risk coupled with feedback and education significantly reduced empiric extended-spectrum antibiotic use among noncritically ill adults admitted with UTI without changing hospital length of stay or days to ICU transfers.

Nasal iodophor antiseptic vs nasal mupirocin antibiotic in the setting of chlorhexidine bathing to prevent infections in adult ICUs: A randomized clinical trial
Huang SS , Septimus EJ , Kleinman K , Heim LT , Moody JA , Avery TR , McLean L , Rashid S , Haffenreffer K , Shimelman L , Staub-Juergens W , Spencer-Smith C , Sljivo S , Rosen E , Poland RE , Coady MH , Lee CH , Blanchard EJ , Reddish K , Hayden MK , Weinstein RA , Carver B , Smith K , Hickok J , Lolans K , Khan N , Sturdevant SG , Reddy SC , Jernigan JA , Sands KE , Perlin JB , Platt R . JAMA 2023 330 (14) 1337-1347 IMPORTANCE: Universal nasal mupirocin plus chlorhexidine gluconate (CHG) bathing in intensive care units (ICUs) prevents methicillin-resistant Staphylococcus aureus (MRSA) infections and all-cause bloodstream infections. Antibiotic resistance to mupirocin has raised questions about whether an antiseptic could be advantageous for ICU decolonization. OBJECTIVE: To compare the effectiveness of iodophor vs mupirocin for universal ICU nasal decolonization in combination with CHG bathing. DESIGN, SETTING, AND PARTICIPANTS: Two-group noninferiority, pragmatic, cluster-randomized trial conducted in US community hospitals, all of which used mupirocin-CHG for universal decolonization in ICUs at baseline. Adult ICU patients in 137 randomized hospitals during baseline (May 1, 2015-April 30, 2017) and intervention (November 1, 2017-April 30, 2019) were included. INTERVENTION: Universal decolonization involving switching to iodophor-CHG (intervention) or continuing mupirocin-CHG (baseline). MAIN OUTCOMES AND MEASURES: ICU-attributable S aureus clinical cultures (primary outcome), MRSA clinical cultures, and all-cause bloodstream infections were evaluated using proportional hazard models to assess differences from baseline to intervention periods between the strategies. Results were also compared with a 2009-2011 trial of mupirocin-CHG vs no decolonization in the same hospital network. The prespecified noninferiority margin for the primary outcome was 10%. RESULTS: Among the 801 668 admissions in 233 ICUs, the participants' mean (SD) age was 63.4 (17.2) years, 46.3% were female, and the mean (SD) ICU length of stay was 4.8 (4.7) days. Hazard ratios (HRs) for S aureus clinical isolates in the intervention vs baseline periods were 1.17 for iodophor-CHG (raw rate: 5.0 vs 4.3/1000 ICU-attributable days) and 0.99 for mupirocin-CHG (raw rate: 4.1 vs 4.0/1000 ICU-attributable days) (HR difference in differences significantly lower by 18.4% [95% CI, 10.7%-26.6%] for mupirocin-CHG, P < .001). For MRSA clinical cultures, HRs were 1.13 for iodophor-CHG (raw rate: 2.3 vs 2.1/1000 ICU-attributable days) and 0.99 for mupirocin-CHG (raw rate: 2.0 vs 2.0/1000 ICU-attributable days) (HR difference in differences significantly lower by 14.1% [95% CI, 3.7%-25.5%] for mupirocin-CHG, P = .007). For all-pathogen bloodstream infections, HRs were 1.00 (2.7 vs 2.7/1000) for iodophor-CHG and 1.01 (2.6 vs 2.6/1000) for mupirocin-CHG (nonsignificant HR difference in differences, -0.9% [95% CI, -9.0% to 8.0%]; P = .84). Compared with the 2009-2011 trial, the 30-day relative reduction in hazards in the mupirocin-CHG group relative to no decolonization (2009-2011 trial) were as follows: S aureus clinical cultures (current trial: 48.1% [95% CI, 35.6%-60.1%]; 2009-2011 trial: 58.8% [95% CI, 47.5%-70.7%]) and bloodstream infection rates (current trial: 70.4% [95% CI, 62.9%-77.8%]; 2009-2011 trial: 60.1% [95% CI, 49.1%-70.7%]). CONCLUSIONS AND RELEVANCE: Nasal iodophor antiseptic did not meet criteria to be considered noninferior to nasal mupirocin antibiotic for the outcome of S aureus clinical cultures in adult ICU patients in the context of daily CHG bathing. In addition, the results were consistent with nasal iodophor being inferior to nasal mupirocin. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03140423. |
Creating rare epilepsy cohorts using keyword search in electronic health records
Barbour K , Tian N , Yozawitz EG , Wolf S , McGoldrick PE , Sands TT , Nelson A , Basma N , Grinspan ZM . Epilepsia 2023 64 (10) 2738-2749 OBJECTIVE: Administrative codes to identify people with rare epilepsies in electronic health records are limited. The current study evaluated the use of keyword search as an alternative method for rare epilepsy cohort creation using electronic health records data. METHODS: Data included clinical notes from encounters with ICD-9 codes for seizures, epilepsy, and/or convulsions during 2010-2014 across six healthcare systems in New York City. We identified cases with rare epilepsies by searching clinical notes for keywords associated with 33 rare epilepsies. We validated cases via manual chart review. We compared performance of keyword search to manual chart review using positive predictive value (PPV), sensitivity, and F-score. We selected an initial combination of keywords using the highest F-scores. RESULTS: Data included clinical notes from 77,924 cases with ICD-9 codes for seizures, epilepsy, and/or convulsions. The all-keyword search method identified 6,095 candidates, and manual chart review confirmed that 2,068 (34%) had a rare epilepsy. The initial combination method identified 1,862 cases with a rare epilepsy, and this method performed as follows: PPV median = 0.64 (interquartile range, IQR = 0.50-0.81, range = 0.20-1.00), sensitivity median = 0.93 (IQR = 0.76-1.00, range = 0.10-1.00), and F-score median = 0.71 (IQR = 0.63-0.85, range = 0.18-1.00). Using this method, we identified four cohorts of rare epilepsies with over 100 individuals, including infantile spasms, Lennox-Gastaut syndrome, Rett syndrome, and tuberous sclerosis complex. We identified over 50 individuals with two rare epilepsies that do not have specific ICD-10 codes for cohort creation (epilepsy with myoclonic atonic seizures, Sturge Weber syndrome). SIGNIFICANCE: Keyword search is an effective method for cohort creation. These findings can improve identification and surveillance of individuals with rare epilepsies and promote their referral to specialty clinics, clinical research, and support groups. |

Alrawashdeh M , Klompas M , Kimmel S , Larochelle MR , Gokhale RH , Dantes RB , Hoots B , Hatfield KM , Reddy SC , Fiore AE , Septimus EJ , Kadri SS , Poland R , Sands K , Rhee C . Crit Care Med 2021 49 (12) 2102-2111 OBJECTIVES: Widespread use and misuse of prescription and illicit opioids have exposed millions to health risks including serious infectious complications. Little is known, however, about the association between opioid use and sepsis. DESIGN: Retrospective cohort study. SETTING: About 373 U.S. hospitals. PATIENTS: Adults hospitalized between January 2009 and September 2015. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Sepsis was identified by clinical indicators of concurrent infection and organ dysfunction. Opioid-related hospitalizations were identified by the International Classification of Diseases, 9th Revision, Clinical Modification codes and/or inpatient orders for buprenorphine. Clinical characteristics and outcomes were compared by sepsis and opioid-related hospitalization status. The association between opioid-related hospitalization and all-cause, in-hospital mortality in patients with sepsis was assessed using mixed-effects logistic models to adjust for baseline characteristics and severity of illness. The cohort included 6,715,286 hospitalizations; 375,479 (5.6%) had sepsis, 130,399 (1.9%) had opioid-related hospitalizations, and 8,764 (0.1%) had both. Compared with sepsis patients without opioid-related hospitalizations (n = 366,715), sepsis patients with opioid-related hospitalizations (n = 8,764) were younger (mean 52.3 vs 66.9 yr) and healthier (mean Elixhauser score 5.4 vs 10.5), had more bloodstream infections from Gram-positive and fungal pathogens (68.9% vs 47.0% and 10.6% vs 6.4%, respectively), and had lower in-hospital mortality rates (10.6% vs 16.2%; adjusted odds ratio, 0.73; 95% CI, 0.60-0.79; p < 0.001 for all comparisons). Of 1,803 patients with opioid-related hospitalizations who died in-hospital, 928 (51.5%) had sepsis. Opioid-related hospitalizations accounted for 1.5% of all sepsis-associated deaths, including 5.7% of sepsis deaths among patients less than 50 years old. From 2009 to 2015, the proportion of sepsis hospitalizations that were opioid-related increased by 77% (95% CI, 40.7-123.5%). CONCLUSIONS: Sepsis is an important cause of morbidity and mortality in patients with opioid-related hospitalizations, and opioid-related hospitalizations contribute disproportionately to sepsis-associated deaths among younger patients. In addition to ongoing efforts to combat the opioid crisis, public health agencies should focus on raising awareness about sepsis among patients who use opioids and their providers. |
Immunoglobulin A Targets a Unique Subset of the Microbiota in Inflammatory Bowel Disease.
Shapiro JM , de Zoete MR , Palm NW , Laenen Y , Bright R , Mallette M , Bu K , Bielecka AA , Xu F , Hurtado-Lorenzo A , Shah SA , Cho JH , LeLeiko NS , Sands BE , Flavell RA , Clemente JC . Cell Host Microbe 2020 29 (1) 83-93 e3 The immunopathogenesis of inflammatory bowel disease (IBD) has been attributed to a combination of host genetics and intestinal dysbiosis. Previous work in a small cohort of IBD patients suggested that pro-inflammatory bacterial taxa are highly coated with secretory immunoglobulin IgA. Using bacterial fluorescence-activated cell sorting coupled with 16S rRNA gene sequencing (IgA-SEQ), we profiled IgA coating of intestinal microbiota in a large cohort of IBD patients and identified bacteria associated with disease and treatment. Forty-three bacterial taxa displayed significantly higher IgA coating in IBD compared with controls, including 8 taxa exhibiting differential IgA coating but similar relative abundance. Patients treated with anti-TNF-α therapies exhibited dramatically altered microbiota-specific IgA responses compared with controls. Furthermore, increased IgA coating of Oscillospira was associated with a delay in time to surgery. These results demonstrate that investigating IgA responses to microbiota can uncover potential disease-modifying taxa and reveal improved biomarkers of clinical course in IBD. |
Erectile dysfunction is highly prevalent in men with newly diagnosed inflammatory bowel disease
Shmidt E , Suarez-Farinas M , Mallette M , Moniz H , Bright R , Shah SA , Merrick M , Shapiro J , Xu F , Saha S , Sands BE . Inflamm Bowel Dis 2019 25 (8) 1408-1416 BACKGROUND AND AIMS: Cross-sectional studies on sexual function in men with inflammatory bowel disease (IBD) yield mixed results. Using a prospective incidence cohort, we aimed to describe sexual function at baseline and over time and to identify factors associated with impaired sexual function in men with IBD. METHODS: Men 18 years and older enrolled between April 2008 and January 2013 in the Ocean State Crohn's and Colitis Area Registry (OSCCAR) with a minimum of 2 years of follow-up were eligible for study. Male sexual function was assessed using the International Index of Erectile Function (IIEF), a self-administered questionnaire that assesses 5 dimensions of sexual function over the most recent 4 weeks. To assess changes in the IIEF per various demographic and clinical factors, linear mixed effects models were used. RESULTS: Sixty-nine of 82 eligible men (84%) completed the questionnaire (41 Crohn's disease, 28 ulcerative colitis). The mean age (SD) of the cohort at diagnosis was 43.4 (19.2) years. At baseline, 39% of men had global sexual dysfunction, and 94% had erectile dysfunction. Independent factors associated with erectile dysfunction are older age and lower physical and mental component summary scores on the Short Form Health Survey (SF-36). CONCLUSION: In an incident cohort of IBD patients, most men had erectile dysfunction. Physicians should be aware of the high prevalence of erectile dysfunction and its associated risk factors among men with newly diagnosed IBD to direct multidisciplinary treatment planning. |
A longitudinal study of sexual function in women with newly diagnosed inflammatory bowel disease
Shmidt E , Suarez-Farinas M , Mallette M , Moniz H , Bright R , Shah SA , Merrick M , Shapiro J , Xu F , Sands B , Saha S . Inflamm Bowel Dis 2019 25 (7) 1262-1270 Background: The literature provides conflicting data on sexual function in women with inflammatory bowel disease (IBD). We aim to describe sexual function at baseline and over time in a prospective inception cohort of adult women with IBD. Methods: Women age 18 years or older enrolled in the Ocean State Crohn's & Colitis Area Registry (OSCCAR) with 2 years of prospective follow-up were included in the study. All subjects were enrolled within 1 year of IBD diagnosis. Female sexual function was assessed using the Female Sexual Function Index (FSFI). Linear mixed effects models were used to assess changes in FSFI by various demographic and clinical factors. Results: One hundred sixteen of 130 eligible women (89%) were included in the study. Ninety-seven percent of women had sexual dysfunction, defined as an FSFI score of <26.55, with a baseline mean FSFI score (SD) of 16.4 (8.4) overall (15.5 [8.6] in Crohn's disease, 17.4 [8.1] in UC, P = 0.22). Despite improvement in overall disease activity, there was no significant change in the FSFI score or individual domain scores over the entire 2-year study period. Among all women with IBD, older age, nonsingle marital status, lower Short Form Health Survey (SF-36) Physical Component Summary score, and the use of biologics were independent risk factors for sexual dysfunction. Conclusions: Almost all women experienced sexual dysfunction that did not improve over time despite improvement in overall disease activity. Future studies are warranted to identify underlying mechanisms that explain the associations between demographic and clinical factors and sexual dysfunction among newly diagnosed women. 10.1093/ibd/izy397_videoizy397_video5999187279001. |
Evaluation of fluidized bed asbestos segregator to determine erionite in soil
Farcas D , Harper M , Januch JW , Jacobs TA , Sarkisian K , Stetler LD , Schwegler-Berry D . Environ Earth Sci 2017 76 (3) 126 Three sets of soil samples were collected by the National Institute for Occupational Safety and Health and one set by South Dakota School of Mines & Technology from in and around the Slim Buttes Land Unit of the Sioux Ranger District of the Custer–Gallatin National Forest in the northwest of South Dakota. The rocks forming the Slim Buttes are sedimentary clays, sands and gravels including re-worked volcanic ash-falls in which the zeolite mineral erionite has crystallized during diagenesis in a fibrous form or morphology similar to that of asbestos. The samples were prepared using the fluidized bed asbestos segregator (FBAS) and analyzed by phase contrast microscopy (PCM) or transmission electron microscopy to detect the presence of mineral fibers. FBAS–PCM results compared to semi-quantitative polarized light microscopy (PLM) and X-ray diffraction analysis indicated a recovery of approximately 1% and a linear relationship that likely can be extrapolated to concentrations well below the 1% detection limit of PLM. There were small variations between a PCM count of 10 fibers to a count of 100 fibers (or a maximum of 200 microscopic fields of view), which indicates the possibility of rapid turnaround of results. Although the four sets of samples examined in this work were collected by slightly different techniques, some tentative conclusions can be drawn about the distribution of erionite in soils. Erionite was detected in almost every soil sample, even those taken several miles from the outcrop, but without any distribution indicating recent transportation from the current volcaniclastic sediment outcrops. Removal of more extensive volcaniclastic sediments through erosion may have resulted in remnant material in soils, including erionite crystals, but this possibility requires further study. Although we have demonstrated that erionite in soils can be detected through FBAS–PCM, we have not attempted to correlate those results with human inhalation exposure through activity-based sampling, and thus, any risk inherent in working these soils is unknown. |
Availability and use of HIV monitoring and early infant diagnosis technologies in WHO Member States in 2011-2013: analysis of annual surveys at the facility level
Habiyambere V , Ford N , Low-Beer D , Nkengasong J , Sands A , Perez Gonzalez M , Fernandes P , Milgotina E . PLoS Med 2016 13 (8) e1002088 BACKGROUND: The Joint United Nations Programme on HIV and AIDS (UNAIDS) 90-90-90 targets have reinforced the importance of functioning laboratory services to ensure prompt diagnosis and to assess treatment efficacy. We surveyed the availability and utilization of technologies for HIV treatment monitoring and early infant diagnosis (EID) in World Health Organization (WHO) Member States. METHODS AND FINDINGS: The survey questionnaire included 14 structured questions focusing on HIV testing, cluster of differentiation 4 (CD4) testing, HIV viral load (VL) testing, and EID and was administered annually from 2012 to 2014 through WHO country offices, with each survey covering the previous 12-mo period. Across 127 targeted countries, survey response rates were 60% in 2012, 67% in 2013, and 78% in 2014. There were encouraging trends towards increased procurement of CD4 and VL/EID instruments in reporting countries. Globally, the capacity of available CD4 instruments was sufficient to meet the demand of all people living with HIV/AIDS (PLWHA), irrespective of treatment status (4.62 theoretical tests per PLWHA in 2013 [median 7.33; interquartile range (IQR) 3.44-17.75; median absolute deviation (MAD) 4.35]). The capacity of VL instruments was inadequate to cover all PLWHA in many reporting countries (0.44 tests per PLWHA in 2013 [median 0.90; IQR 0.30-2.40; MAD 0.74]). Of concern, only 13.7% of existing CD4 capacity (median 4.3%; IQR 1.1%-12.1%; MAD 3.8%) and only 36.5% of existing VL capacity (median 9.4%; IQR 2.3%-28.9%; MAD 8.2%) was being utilized across reporting countries in 2013. By the end of 2013, 7.4% of all CD4 instruments (5.8% CD4 conventional instruments and 11.0% of CD4 point of care [POC]) and 10% of VL/EID instruments were reportedly not in use because of lack of reagents, the equipment not being installed or deployed, maintenance, and staff training requirements. Major limitations of this survey included under-reporting and/or incomplete reporting in some national programmes and noncoverage of the private sector. CONCLUSION: This is the first attempt to comprehensively gather information on HIV testing technology coverage in WHO Member States. The survey results suggest that major operational changes will need to be implemented, particularly in low- and middle-income countries, if the 90-90-90 targets are to be met. |

Inflamm Bowel Dis 2016 22 (6) 1456-61 BACKGROUND: Studies describing the incidence of Crohn's disease (CD) and ulcerative colitis (UC) are uncommon in the United States. We sought to determine the incidence of CD and UC in the state of Rhode Island. METHODS: The Ocean State Crohn's and Colitis Area Registry is a state-based inception cohort of patients newly diagnosed with inflammatory bowel disease (IBD) in Rhode Island. To confirm a diagnosis of CD, UC, or IBD unclassified (IBDU), the National Institute of Diabetes and Digestive and Kidney Diseases IBD Genetics Consortium criteria were applied in a review of medical records from gastroenterology practices located in the state of Rhode Island and adjacent to the Rhode Island border in Massachusetts and Connecticut. Using population-based data, we determined the statewide incidence of IBD in Rhode Island from 2008 to 2010. RESULTS: A total of 971 Rhode Island residents were diagnosed with IBD, including 444 with CD, 486 with UC, and 41 with IBD unclassified from 2008 to 2010. The overall age- and sex-adjusted IBD incidence was 30.2 (95% confidence interval, 28.3-32.1) per 100,000 persons in this time frame with 13.9, 15.1, and 1.3 per 100,000 diagnosed with CD, UC, and IBD unclassified, respectively. Of the total incident cases in Rhode Island, 30% (n = 291) were enrolled in Ocean State Crohn's and Colitis Area Registry for follow-up. CONCLUSIONS: The incidence of IBD in Rhode Island is higher than that previously reported by other population-based cohorts in the United States. Prospective follow-up of individuals enrolled in the community-based Ocean State Crohn's and Colitis Area Registry cohort is ongoing. |

Abdom Radiol (NY) 2016 41 (7) 1363-9 PURPOSE: Patients with inflammatory bowel disease (IBD) may be exposed to high doses of diagnostic radiation. The purpose of this study is to identify subsets of this population at risk for significant radiation exposure. METHODS: This HIPAA compliant, IRB approved study consists of 336 patients (237 adult and 99 pediatric) within the Ocean State Crohn's & Colitis Area Registry (OSCCAR). All were newly diagnosed with IBD and prospectively enrolled between 1/2008 and 12/2012. Comprehensive chart review was performed. RESULTS: 207 (61.6%) patients were diagnosed with Crohn's disease (CD), 120 (35.7%) with ulcerative colitis (UC), and 9 (2.7%) with inflammatory bowel disease, type unspecified (IBDU). 192 (57.1%) patients were exposed to GI-specific radiation. Average GI-specific radiation dose for adult IBD patients was 14.1 mSV and was significantly greater among adult CD than adult UC patients (p = 0.01). Pediatric patients underwent fewer CT scans (p < 0.0001). Risk factors for increased radiation exposure include: GI surgery (p = 0.003), biologic therapy (p = 0.01), pain-predominant symptoms (as compared to diarrhea-predominant symptoms; p < 0.05), and isolated ileal disease (p = 0.02). Patients with stricturing or penetrating disease received higher radiation doses than patients with non-stricturing, non-penetrating disease (p < 0.0001). CONCLUSIONS: A variety of risk factors are associated with increased exposure to ionizing radiation after diagnosis of IBD. Knowledge of these risk factors can help physicians prospectively identify patients at risk for elevated radiation exposure and consider low-dose or radiation-free imaging. |
Corticosteroid use in a prospective, community-based cohort of newly diagnosed inflammatory bowel disease patients
Shapiro JM , Hagin SE , Shah SA , Bright R , Law M , Moniz H , Giacalone J , Jackvony T , Taleban S , Samad Z , Merrick M , Sands BE , LeLeiko NS . Dig Dis Sci 2016 61 (6) 1635-40 BACKGROUND: Systemic corticosteroids (CS) are a mainstay of treatment for patients with newly diagnosed inflammatory bowel disease (IBD). Previous population-based studies report CS exposure rates range from 39 to 75 % within the first year of diagnosis with surgical resection rates as high as 13-18 % in the same time frame. These reports represent an older cohort of patients enrolled over prolonged periods of time and do not necessarily reflect current treatment approaches. We examine CS use during the first year of IBD diagnosis in a community-based, inception cohort. METHODS: Data were derived from the Ocean State Crohn's and Colitis Area Registry (OSCCAR), a prospective inception cohort of IBD patients who are residents of Rhode Island. RESULTS: A total of 272 patients were included in the current analyses. Overall, 60 % of Crohn's disease and 57 % of ulcerative colitis patients were exposed to at least one course of CS during year 1 of study enrollment. Most notably, only 2 % of patients (n = 5) required a surgical resection. CONCLUSIONS: In this community-based cohort, 59 % of patients were exposed to at least one course of CS during their first year of enrollment. In contrast to previous studies, OSCCAR represents a more modern cohort of patients. While steroid exposure rates were similar or slightly higher than those in previous reports, we observed a low rate of surgical resection. As our cohort ages, future analysis will focus on the role more contemporary agents may play on the low rates of surgery we observed. |
Body image dissatisfaction in patients with inflammatory bowel disease
Saha S , Zhao Y , Shah SA , Esposti SD , Lidofsky S , Bright R , Law M , Moniz H , Samad Z , Merrick M , Sands BE . Inflamm Bowel Dis 2015 21 (2) 345-52 BACKGROUND: Despite the fact that the inflammatory bowel diseases (IBD) and their treatments may affect physical appearance, the effect of IBD on body image is poorly understood. The aims of this study were to determine whether body image dissatisfaction (BID) changes over time in patients with IBD and to examine the demographic and disease-related variables associated with decreased body image. METHODS: Adults aged 18 and above in the Ocean State Crohn's and Colitis Area Registry with at least 2 years of follow-up were eligible for this study. All patients were enrolled within 6 months of IBD diagnosis and followed prospectively. BID was assessed using a modified version of the Adapted Satisfaction With Appearance questionnaire. Total Adapted Satisfaction With Appearance scores and 2 subscores were calculated. To assess for changes over time, general linear models for correlated data were used for continuous outcomes, and generalized estimating equations were used for discrete outcomes. RESULTS: Two hundred seventy-four patients were studied. BID was found to be stable over time among men and women with IBD despite overall improvements in disease activity. No differences were found in BID according to IBD subtype. Female gender, greater disease activity, higher symptom burden, longer duration of steroid use, dermatologic and musculoskeletal manifestations of IBD, and ileocolonic disease location among patients with Crohn's disease were associated with greater BID. Greater BID was associated with lower health-related quality of life. CONCLUSIONS: BID remains stable in an incident cohort of IBD despite improved disease activity and is associated with lower health-related quality of life. |
Fatigue is highly associated with poor health-related quality of life, disability and depression in newly-diagnosed patients with inflammatory bowel disease, independent of disease activity
Cohen BL , Zoega H , Shah SA , Leleiko N , Lidofsky S , Bright R , Flowers N , Law M , Moniz H , Merrick M , Sands BE . Aliment Pharmacol Ther 2014 39 (8) 811-22 BACKGROUND: Fatigue is common in Crohn's disease (CD) and ulcerative colitis (UC). Data on fatigue in newly diagnosed patients are unavailable. AIM: To report prevalence of fatigue in newly diagnosed CD and UC patients and examine its association with health-related quality of life (HRQOL), depression and disability. METHODS: The Ocean State Crohn's and Colitis Area Registry (OSCCAR) is a statewide cohort of newly diagnosed inflammatory bowel disease patients in Rhode Island. Fatigue was assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue Scale. Patients were administered instruments measuring HRQOL, overall disability and work impairment, and depression. RESULTS: Fatigue was prevalent in 26.4% of 220 subjects. Cohen's d effect sizes for fatigue were large: Short-Form 36 Health Survey mental health component (CD 1.5, UC 1.4) and physical health component (CD 1.4, UC 1.4), EuroQol-5D valuation of current health state (CD 1.2, UC 1.0), Inflammatory Bowel Disease Questionnaire (CD 1.9, UC 1.6) and Patient Health Questionnaire depression scale (CD 1.8, UC 1.7). Fatigued patients reported more work impairment (Score difference: CD 29.5%, UC 23.8%) and activity impairment (score difference: CD 32.3%, UC 25.7%) on the Work Productivity and Activity Impairment Questionnaire. Fatigue's association with all scores remained highly significant despite controlling for disease activity. CONCLUSIONS: Fatigue is strongly associated with poor HRQOL, disability and depression similarly in CD and UC even when controlling for disease activity. Fatigue's association with a wide range of patient-reported outcome measures suggests that monitoring fatigue is a simple way to screen for overall disruption in patient life. |
Menstrual cycle changes in women with inflammatory bowel disease: a study from the Ocean State Crohn's and Colitis Area Registry
Saha S , Zhao YQ , Shah SA , Esposti SD , Lidofsky S , Salih S , Bright R , Law M , Moniz H , Flowers N , Merrick M , Sands BE . Inflamm Bowel Dis 2014 20 (3) 534-40 BACKGROUND: The effect of the inflammatory bowel diseases (IBD) on menstrual function is largely unknown. The aims of this study were to determine whether changes in menstrual function occur in the year before IBD diagnosis or in the initial years after diagnosis. METHODS: Women aged 18 years and older in the Ocean State Crohn's and Colitis Area Registry with at least 2 years of follow-up were eligible for this study. All patients were enrolled within 6 months of IBD diagnosis and followed prospectively. Menstrual cycle characteristics were retrospectively assessed. To assess for changes over time, general linear models for correlated data were used for continuous outcomes, and generalized estimating equations were used for discrete outcomes. RESULTS: One hundred twenty-one patients were studied. Twenty-five percent of patients experienced a change in cycle interval in the year before IBD diagnosis and 21% experienced a change in the duration of flow. Among women with dysmenorrhea, 40% experienced a change in the intensity of their menstrual pain and 31% experienced a change in its duration. Overall cycle regularity increased over time. Quality of life was significantly lower in women without regular cycles across all time points. CONCLUSIONS: Changes in menstrual function occur frequently in the year before IBD diagnosis; therefore, screening for menstrual irregularities should be considered in women with newly diagnosed IBD. Patients can be reassured that cycles typically become more regular over time. |
Prevalence of human papillomavirus types in invasive vulvar cancers and vulvar intraepithelial neoplasia 3 in the United States before vaccine introduction
Gargano JW , Wilkinson EJ , Unger ER , Steinau M , Watson M , Huang Y , Copeland G , Cozen W , Goodman MT , Hopenhayn C , Lynch CF , Hernandez BY , Peters ES , Saber MS , Lyu CW , Sands LA , Saraiya M . J Low Genit Tract Dis 2012 16 (4) 471-9 OBJECTIVE: The study aimed to determine the baseline prevalence of human papillomavirus (HPV) types in invasive vulvar cancer (IVC) and vulvar intraepithelial neoplasia 3 (VIN 3) cases using data from 7 US cancer registries. MATERIALS AND METHODS: Registries identified eligible cases diagnosed in 1994 to 2005 and requested pathology laboratories to prepare 1 representative block for HPV testing on those selected. Hematoxylin-eosin-stained sections preceding and following those used for extraction were reviewed to confirm representation. Human papillomavirus was detected using L1 consensus polymerase chain reaction (PCR) with PGMY9/11 primers and type-specific hybridization, with retesting of samples with negative and inadequate results with SPF10 primers. For IVC, the confirmatory hematoxylin-eosin slides were re-evaluated to determine histological type. Descriptive analyses were performed to examine distributions of HPV by histology and other factors. RESULTS: Human papillomavirus was detected in 121/176 (68.8%) cases of IVC and 66/68 (97.1%) cases of VIN 3 (p < .0001). Patients with IVC and VIN 3 differed by median age (70 vs 55 y, p = .003). Human papillomavirus 16 was present in 48.6% of IVC cases and 80.9% of VIN 3 cases; other high-risk HPV was present in 19.2% of IVC cases and 13.2% of VIN 3 cases. Prevalence of HPV differed by squamous cell carcinoma histological subtype (p < .0001) as follows: keratinizing, 49.1% (n = 55); nonkeratinizing, 85.7% (n = 14), basaloid, 92.3% (n = 14), warty 78.2% (n = 55), and mixed warty/basaloid, 100% (n = 7). CONCLUSIONS: Nearly all cases of VIN 3 and two thirds of IVC cases were positive for high-risk HPV. Prevalence of HPV ranged from 49.1% to 100% across squamous cell carcinoma histological subtypes. Given the high prevalence of HPV in IVC and VIN 3 cases, prophylactic vaccines have the potential to decrease the incidence of vulvar neoplasia. |
Hepatitis C virus infections from unsafe injection practices at an endoscopy clinic in Las Vegas, Nevada, 2007-2008
Fischer GE , Schaefer MK , Labus BJ , Sands L , Rowley P , Azzam IA , Armour P , Khudyakov YE , Lin Y , Xia G , Patel PR , Perz JF , Holmberg SD . Clin Infect Dis 2010 51 (3) 267-73 BACKGROUND: In January 2008, 3 persons with acute hepatitis C who all underwent endoscopy at a single facility in Nevada were identified. METHOD: We reviewed clinical and laboratory data from initially detected cases of acute hepatitis C and reviewed infection control practices at the clinic where case patients underwent endoscopy. Persons who underwent procedures on days when the case patients underwent endoscopy were tested for hepatitis C virus (HCV) infection and other bloodborne pathogens. Quasispecies analysis determined the relatedness of HCV in persons infected. RESULTS: In addition to the 3 initial cases, 5 additional cases of clinic-acquired HCV infection were identified from 2 procedure dates included in this initial field investigation. Quasispecies analysis revealed 2 distinct clusters of clinic-acquired HCV infections and a source patient related to each cluster, suggesting separate transmission events. Of 49 HCV-susceptible persons whose procedures followed that of the source patient on 25 July 2007, 1 (2%) was HCV infected. Among 38 HCV-susceptible persons whose procedures followed that of another source patient on 21 September 2007, 7 (18%) were HCV infected. Reuse of syringes on single patients in conjunction with use of single-use propofol vials for multiple patients was observed during normal clinic operations. CONCLUSION: Patient-to-patient transmission of HCV likely resulted from contamination of single-use medication vials that were used for multiple patients during anesthesia administration. The resulting public health notification of approximately 50,000 persons was the largest of its kind in United States health care. This investigation highlighted breaches in aseptic technique, deficiencies in oversight of outpatient settings, and difficulties in detecting and investigating such outbreaks. |
