RESUMO
OBJECTIVE: Despite effective treatment options for posttraumatic stress disorder (PTSD), many patients do not complete therapy. This includes U.S. active duty service members, yet factors linked to attendance in this population remain understudied and dropout remains difficult to predict. Additionally, most studies have not examined samples with PTSD and co-occurring major depressive disorder (MDD) despite high rates of comorbidity. METHOD: The current study explored predictors of dropout among service members with comorbid PTSD and MDD (N = 94) randomized to cognitive processing therapy enhanced with behavioral activation (BA + CPT) or CPT as part of a clinical trial. RESULTS: Using the Fournier approach, only two predictors were associated with lower dropout risk among over 20 examined: shorter duration between pretreatment assessment and Session 1 (p = .041) and past 3-month PTSD treatment engagement (p = .036). CONCLUSION: Results suggest the possible utility of early momentum in starting therapy and leveraging recent treatment to improve attendance. However, this study also highlights the possible limitations of commonly assessed pretreatment factors in predicting attendance and current challenges in measuring dropout risk. Strategies to improve prediction, such as shifting focus to assess modifiable factors and processes more proximal to dropout during treatment, may be needed.Trial registration: ClinicalTrials.gov identifier: NCT02874131.
RESUMO
BACKGROUND: Infective endocarditis (IE) has high morbidity and mortality and is often attributed to dental procedures. AIM: This study characterized variables related to paediatric IE in a paediatric hospital cohort. DESIGN: A retrospective review of medical records, from January 1, 2008, to January 1, 2020, to examine demographic, medical and dental history, and risk factors associated with children diagnosed with IE at Nationwide Children's Hospital. RESULTS: Of the 242 patients who were admitted with tentative IE diagnoses, 67 met the inclusion criteria: 46 (69%) had underlying cardiac conditions and 21 (31%) had not. One-third had an infection with S. aureus and viridans streptococci. Age was significantly associated with intracardiac devices in children with IE. Mean hospitalization was 25 days, and the mortality was 6 (9%); 41(61%) required surgery for causative defects, and 24 (32%) had dental consultation during admission. CONCLUSION: Although cardiac-related conditions were present in most cases, IE occurred in patients without cardiac factors.

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) frequently co-occur and can cause significant impairment. Data are lacking as to whether interventions targeting both PTSD and MDD may improve treatment outcomes among individuals with this comorbidity compared with existing evidence-based PTSD treatments alone. This randomized trial compared the effectiveness of cognitive processing therapy (CPT) enhanced with behavioral activation (BA+CPT) versus CPT among 94 service members (52 women and 42 men; age M = 28.5 years) with comorbid PTSD and MDD. The primary outcome was clinician-administered depression symptom severity on the Montgomery-Åsberg Depression Rating Scale (MADRS) from pretreatment through 3-month follow-up. Intent-to-treat analyses using multilevel models showed statistically and clinically significant decreases in MADRS scores for both conditions over time, with no significant differences between BA+CPT and CPT. Secondary depression and PTSD symptom outcomes followed a similar pattern of results. For diagnostic MDD and PTSD outcomes using available data, no statistically significant differences between treatments emerged at posttreatment or 3-month follow-up. Sessions attended, dropout rate, and treatment satisfaction did not significantly differ between treatments. Outcomes were comparable for both treatments, suggesting that BA+CPT and CPT were similarly effective psychotherapy options for comorbid PTSD and MDD.

The design, manufacture, and commissioning of a global positioning system enabled sampler instrument conceived for the retrieval of seabed sediments are described. This system was designed for sampling in environmental assessment applications and, especially, those requirements that might include insoluble, anthropogenic radioactivity derived from the effluent from nuclear facilities. Once triggered, the sampler operates autonomously for the recovery of samples by settling in the sampling environment, and it is compatible with submersion in fresh water and also with an off-the-shelf, submersible, remotely operated vehicle. A number of tests have been carried out to determine the efficiency and efficacy of the sample recovery performed by the system and the extent to which the recovery of samples disturbs neighboring sediments.

BACKGROUND: The British Association of Dermatologists (BAD) develops and produces patient information leaflets (PILs) for British clinicians and the general public, and its website provides access to all the PILs. Health literacy across the UK remains variable. Readability instruments assess the comprehensibility of text, predominately using a composite of sentence length and/or word-syllable number. Instruments usually report text readability categorized by United States (US) grades; ideally, health literature should be rated at US grade ≤ 6 (UK Year 7; age 11-12 years). METHODS: In collaboration with the BAD, PILs on the BAD website (n = 203) were downloaded for readability assessment. PILs were processed prior to analysis using Readability Studio software (Oleander Software, Vandalia, OH, USA). Established readability metrics were used: Flesch-Kincaid (FK), Simple Measure of Gobbledygook (SMOG), Gunning fog index (GFI), Fry, FORCAST and Flesch Reading Ease (FRE). RESULTS: The mean (95% CI) US grade levels for all BAD PILs were: 9.8 (9.7-10.0) for FK, 12.1 (12.0-12.3) for SMOG, 11.8 (11.6-11.9) for GFI, 11.5 (11.1-11.8) for Fry and 10.7 (10.6-10.8) for FORCAST. For FRE, the level is reported from a normal spectrum of 0-100, and was found to be 52.2 (95% CI 34.0-78.0) in this study. In the UK context, the mean readability levels of the BAD PILs were rated as Year 10 (age 14-15 years) for FK and Year 13 (aged 17-18 years) for SMOG. For FK, outputs, only 1.0% of PILs (2 of 203) were the recommended US grade ≤ 6 according to FK, and for SMOG rating, none was rated at this level. DISCUSSION: The majority of BAD PILs have been written at a level that will be challenging for some patients to read. Reducing sentence length and aiming for shorter words will improve accessibility.

Abdominal pain, nausea, and vomiting are known gastrointestinal symptoms of symptomatic SARS-CoV-2 infection (COVID-19 disease) in pediatric patients.1 There is little literature regarding pancreatitis in COVID-19. We describe a 16-year-old male diagnosed with acute pancreatitis in the setting of a SARS-COV-2 infection and associated fluid balance considerations.
RESUMO
BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that emerged recently and has created a global pandemic. Symptomatic SARS-CoV-2 infection, termed coronavirus disease 2019 (COVID-19), has been associated with a host of symptoms affecting numerous organ systems, including the lungs, cardiovascular system, kidney, central nervous system, gastrointestinal tract, and skin, among others. OBJECTIVE: Although several risk factors have been identified as related to complications from and severity of COVID-19, much about the virus remains unknown. The host immune response appears to affect the outcome of disease. It is not surprising that patients with intrinsic or secondary immune compromise might be particularly susceptible to complications from SARS-CoV-2 infection. Pathogenic loss-of-function or gain-of-function heterozygous variants in nuclear factor-κB2 have been reported to be associated with either a combined immunodeficiency or common variable immunodeficiency phenotype. METHODS: We evaluated the functional consequence and immunologic phenotype of a novel NFKB2 loss of function variant in a 17-year-old male patient and describe the clinical management of SARS-CoV-2 infection in this context. RESULTS: This patient required a 2-week hospitalization for SARS-CoV-2 infection, including 7 days of mechanical ventilation. We used biologic therapies to avert potentially fatal acute respiratory distress syndrome and treat hyperinflammatory responses. The patient had an immunologic phenotype of B-cell dysregulation with decreased switched memory B cells. Despite the underlying immune dysfunction, he recovered from the infection with intense management. CONCLUSIONS: This clinical case exemplifies some of the practical challenges in management of patients with SARS-CoV-2 infection, especially in the context of underlying immune dysregulation.

BACKGROUND: Hepatitis in young children with tuberculosis (TB) outside miliary TB is not well described and represents a challenge because of the hepatotoxicity associated with first-line anti-TB treatment. CASE PRESENTATION: We report an antibiotic naïve 13-month-old male from Nepal with pulmonary TB and hepatitis, who improved after TB treatment. We also performed a literature review for TB-associated hepatitis in children. CONCLUSIONS: Liver function tests should be considered, when feasible, in infants and young children with pulmonary TB. Testing could help to identify and manage patients with TB-associated hepatic abnormalities, and also to establish a baseline for detection and management of liver injury associated with anti-TB therapy.

Bovine tuberculosis (BTB) testing in cattle requires a significant investment of time, equipment, and labor. Novel, rapid, cheaper and accurate methods are needed. The Alere Determine TB lipoarabinomannan antigen (LAM-test) is a World Health Organization-endorsed point-of-care urine test designed to detect active TB disease in humans. The Lionex Animal TB Rapid Test (Lionex-test) is a novel animal specific TB diagnostic blood test. An animal level analysis was performed using urine (n = 141) and milk (n = 63) samples from depopulated BTB-suspected cattle to test the accuracy of the LAM-test when compared to results of positive TB detection by any routine BTB tests (BOVIGAM, necropsy, histology, culture, PCR) that are regularly performed by the United States Department of Agriculture (USDA). The agreement between the urine LAM-test and USDA standard tests were poor at varying testing time points. The same milk samples did not elicit statistically significant agreement with the Lionex-test, although positive trends were present. Hence, we cannot recommend the LAM-test as a valid BTB diagnostic test in cattle using either urine or milk. The Lionex-test's production of positive trends using milk samples suggests larger sample sizes may validate the Lionex-test in accurately diagnosing BTB in cattle using milk samples, potentially providing a quick and reliable field test for BTB.

Noise pollution is increasing globally, and as oceans are excellent conductors of sound, this is a major concern for marine species reliant on sound for key life functions. Loud, impulsive sounds from seismic surveys have been associated with impacts on many marine taxa including mammals, crustaceans, cephalopods, and fish. However, impacts across large spatial scales or multiple species are rarely considered. We modelled over 8,000 hours of cetacean survey data across a large marine ecosystem covering > 880,000 km2 to investigate the effect of seismic surveys on baleen and toothed whales. We found a significant effect of seismic activity across multiple species and habitats, with an 88% (82-92%) decrease in sightings of baleen whales, and a 53% (41-63%) decrease in sightings of toothed whales during active seismic surveys when compared to control surveys. Significantly fewer sightings of toothed whales also occurred during active versus inactive airgun periods of seismic surveys, although some species-specific response to noise was observed. This study provides strong evidence of multi-species impacts from seismic survey noise on cetaceans. Given the global proliferation of seismic surveys and large propagation distances of airgun noise, our results highlight the large-scale impacts that marine species are currently facing.
RESUMO
BACKGROUND: Bovine tuberculosis (bTB) is prevalent in dairy cattle in Ethiopia. Currently used diagnostic tools such as the single intradermal comparative tuberculin test (SICTT) are time consuming and labor intensive. A rapid, easy-to-use and cost-effective diagnostic test would greatly contribute to the control of bTB in developing countries like Ethiopia. In the present study, two point-of-care diagnostic tests were evaluated for the detection of bTB: LIONEX® Animal TB Rapid test, a membrane-based test for the detection of antibodies to Mycobacterium bovis in blood and ALERE® Determine TB Lipoarabinomannan (LAM) Ag, an immunoassay for the detection of lipoarabinomannan (LAM) antigen (Ag) of mycobacteria in urine. A combination of the SICTT and gamma interferon (IFN-γ) test was used as the gold standard for the validation of these point-of-care tests, as it was not feasible to slaughter the study animals to carry out the historical gold standard of mycobacterial culture. A total of 175 heads of cattle having three different bTB infection categories (positive SICTT, negative SICTT, and unknown SICTT status) were used for this study. RESULT: The sensitivity and specificity of TB LAM Ag were 72.2% (95% CI = 62.2, 80.4) and 98.8% (95% CI = 93.6, 99.7), respectively, while the sensitivity and specificity of the LIONEX Animal TB rapid test assay were 54% (95% CI = 44.1 64.3) and 98.8% (95% CI = 93.6, 99.7) respectively. The agreement between TB LAM Ag and SICTT was higher (κ = 0.85; 95% CI = 0.65-0.94) than between TB LAM Ag and IFN-γ (κ = 0.67; 95% CI = 0.52-0.81). The agreement between LIONEX Animals TB Rapid blood test and SICTT was substantial, (κ = 0.63; 95% CI = 0.49-0.77) while the agreement between LIONEX Animal TB rapid blood test and IFN-γ test was moderate (κ = 0.53; 95% CI = 0.40-0.67). Analysis of receiver operating curve (ROC) indicated that the area under the ROC curve (AUC) for TB LAM Ag was 0.85 (95% CI = 0.79-0.91) while it was 0.76 (95% CI; =0.69-0.83) for LIONEX Animal TB rapid test assay. CONCLUSION: This study showed that TB LAM Ag had a better diagnostic performance and could potentially be used as ancillary either to SICTT or IFN-γ test for diagnosis of bTB.

Timely diagnosis of tuberculosis (TB) is limited in Ethiopia. We evaluated the performance of a low technology, thin layer agar, Mycobacterium tuberculosis (M.tb) culture color plate (TB-CX) test with concurrent drug susceptibility testing (DST) to isoniazid (INH), rifampin (RIF), and pyrazinamide (PZA) directly from sputum specimens. Patients undergoing examination for TB and multidrug-resistant (MDR)-TB were enrolled in Addis Ababa, Ethiopia from March 2016 to February 2017. All subjects received a GeneXpert MTB/RIF PCR test. TB-CX test results were compared to reference Löwenstein-Jensen (LJ) culture for M.tb detection and DST for susceptibility to INH and RIF. Kappa statistic was applied to test agreement between results for TB-CX test and the reference methods, a cut-off Kappa value of 0.75 was considered as high level of agreements. A total of 137 participants were analyzed: 88 (64%) were new TB cases, 49 (36%) were re-treatment cases. The TB-CX test detected M.tb and DST in an average of 13 days compared to 50 days for the conventional DST result. The sensitivity and specificity of the TB-CX test for detecting M.tb were 94% and 98%, respectively (concordance, 96%; kappa 0.91). The sensitivity of the TB-CX test to detect drug resistance to INH, RIF, and MDR-TB was 91%, 100%, and 90% respectively. The specificity of the TB-CX test for detecting INH, RIF, and MDR-TB was 94%, 40%, and 94% respectively. Overall agreement between TB-CX test and LJ DST for detection of MDR-TB was 93%. The TB-CX test showed strong agreement with the GeneXpert test for detecting M.tb (89%, kappa 0.76) but low agreement for the detection of RIF resistance (57%, kappa 0.28). The TB-CX test was found to be a good alternative method for screening of TB and selective drug resistant-TB in a timely and cost-efficient manner.

We identified 13 patients with cat scratch (Bartonella henselae) bone infection among those admitted to a large tertiary care children's hospital over a 12-year period. The median age was 7 years and the median time from onset of illness to diagnosis was 10 days. Multifocal osteomyelitis involving spine and pelvis was common; no patient had a lytic bone lesion. Median treatment duration was 28 days (IQR, 24.5 days). Despite significant variations in treatment duration and antimicrobial therapy choices, all patients showed improvement.

Posttraumatic stress disorder (PTSD) commonly co-occurs with major depressive disorder (MDD) in both civilian and military/veteran populations. Existing, evidence-based PTSD treatments, such as cognitive processing therapy (CPT), often reduce symptoms of both PTSD and depression; however, findings related to the influence of comorbid MDD on PTSD treatment outcomes are mixed, and few studies use samples of individuals with both conditions. Behavioral activation (BA), an approach that relies on behavioral principles, is an effective treatment for depression. We have integrated BA into CPT (BA+CPT), a more cognitive approach, to address depressive symptoms among active duty service members with both PTSD and comorbid MDD. We describe an ongoing randomized controlled trial investigating the efficacy of our innovative, integrated BA+CPT intervention, compared with standard CPT, for active duty service members with PTSD and comorbid MDD. We detail the development of this integrated treatment, as well as the design and implementation of the randomized controlled trial, to evaluate its effect on symptoms.

Raptors are exposed to a wide variety of human-related mortality agents, and yet population-level effects are rarely quantified. Doing so requires modeling vital rates in the context of species life-history, behavior, and population dynamics theory. In this paper, we explore the details of such an analysis by focusing on the demography of a resident, tree-nesting population of golden eagles (Aquila chrysaetos) in the vicinity of an extensive (142 km2) windfarm in California. During 1994-2000, we tracked the fates of >250 radio-marked individuals of four life-stages and conducted five annual surveys of territory occupancy and reproduction. Collisions with wind turbines accounted for 41% of 88 uncensored fatalities, most of which were subadults and nonbreeding adults (floaters). A consistent overall male preponderance in the population meant that females were the limiting sex in this territorial, monogamous species. Estimates of potential population growth rate and associated variance indicated a stable breeding population, but one for which any further decrease in vital rates would require immigrant floaters to fill territory vacancies. Occupancy surveys 5 and 13 years later (2005 and 2013) showed that the nesting population remained intact, and no upward trend was apparent in the proportion of subadult eagles as pair members, a condition that would have suggested a deficit of adult replacements. However, the number of golden eagle pairs required to support windfarm mortality was large. We estimated that the entire annual reproductive output of 216-255 breeding pairs would have been necessary to support published estimates of 55-65 turbine blade-strike fatalities per year. Although the vital rates forming the basis for these calculations may have changed since the data were collected, our approach should be useful for gaining a clearer understanding of how anthropogenic mortality affects the health of raptor populations, particularly those species with delayed maturity and naturally low reproductive rates.

The carbon sequestration services of stormwater wet retention ponds were investigated in four different climates: U.S., Northern Sweden, Southern Sweden, and Singapore, representing a range of annual mean temperatures, growing season lengths and rainfall depths: geographic factors that were not statistically compared, but have great effect on carbon (C) accumulation. A chronosequence was used to estimate C accumulations rates; C accumulation and decomposition rates were not directly measured. C accumulated significantly over time in vegetated shallow water areas (0-30cm) in the USA (78.4gCm-2yr-1), in vegetated temporary inundation zones in Sweden (75.8gCm-2yr-1), and in all ponds in Singapore (135gCm-2yr-1). Vegetative production appeared to exert a stronger influence on relative C accumulation rates than decomposition. Comparing among the four climatic zones, the effects of increasing rainfall and growing season lengths (vegetative production) outweighed the effects of higher temperature on decomposition rates. Littoral vegetation was a significant source to the soil C pool relative to C sources draining from watersheds. Establishment of vegetation in the shallow water zones of retention ponds is vital to providing a C source to the soil. Thus, the width of littoral shelves containing this vegetation along the perimeter may be increased if C sequestration is a design goal. This assessment establishes that stormwater wet retention ponds can sequester C across different climate zones with generally annual rainfall and lengths of growing season being important general factors for C accumulation.
