The effects of various solutions and levels of desiccation on the survival of Trichobilharzia stagnicolae miracidia

ParasitologyMiracidia of Trichobilharzia stagnicolae were placed under two tests: one test examined the longevity of miracidia in various aqueous solutions; the other test examined the effects of desiccation on the hatching of miracidia from eggs. For the solutions test, we used five different solutions: filtered lake water, distilled water, well water, distilled water with 10% sucrose, and avian ringers. Longevity of miracidia was the greatest in filtered lake water and distilled water respectively. For the desiccation test, the number of miracidia hatching from eggs decreased as time allowed for desiccation increased. Further analysis suggested that longevity of miracidia is greatly decreased in hyperosmotic solutions.http://deepblue.lib.umich.edu/bitstream/2027.42/61482/1/Uremek_Clune_Foster_Kuo_2008.pd

Longevity of Trichobilharzia stagnicolae miracidia in various aqueous solutions and during desiccation

ParasitologySwimmer’s itch is caused by nonhuman schistosomes, including Trichobilharzia stagnicolae, which have complex indirect life cycles. Miracidia are a free living life cycle stage of these schistosomes that are transmitted from either an avian or mammalian host to a specific snail intermediate, depending on the species. The goals of this study are to determine the life span of the miracidia of T. stagnicolae in various solutions and to examine the effect of desiccation on the hatching ability of miracidia. Miracidia were hatched and placed in dishes of five different solutions (filtered lake water, well water, distilled water, distilled water with sucrose and avian ringers) to determine their life span. Samples of host fecal material were dried and miracidia were hatched from these samples to test the effects of desiccation. Longevity of miracidia was greatest in filtered lake water and distilled water. Hatching ability decreased with the amount of water evaporated from the fecal samples (p = 4.03x10-10). These results suggest that T. stagnicolae miracidia are sensitive to hyperosmotic solutions and that once they hatch, they lose many protective functions provided by the egg.http://deepblue.lib.umich.edu/bitstream/2027.42/61481/1/Clune_Foster_Kuo_Uremek_2008.pd

Simulating Developmental Cardiac Morphology in Virtual Reality Using a Deformable Image Registration Approach

While virtual reality (VR) has potential in enhancing cardiovascular diagnosis and treatment, prerequisite labor-intensive image segmentation remains an obstacle for seamlessly simulating 4-dimensional (4-D, 3-D + time) imaging data in an immersive, physiological VR environment. We applied deformable image registration (DIR) in conjunction with 3-D reconstruction and VR implementation to recapitulate developmental cardiac contractile function from light-sheet fluorescence microscopy (LSFM). This method addressed inconsistencies that would arise from independent segmentations of time-dependent data, thereby enabling the creation of a VR environment that fluently simulates cardiac morphological changes. By analyzing myocardial deformation at high spatiotemporal resolution, we interfaced quantitative computations with 4-D VR. We demonstrated that our LSFM-captured images, followed by DIR, yielded average dice similarity coefficients of 0.92 ± 0.05 (n = 510) and 0.93 ± 0.06 (n = 240) when compared to ground truth images obtained from Otsu thresholding and manual segmentation, respectively. The resulting VR environment simulates a wide-angle zoomed-in view of motion in live embryonic zebrafish hearts, in which the cardiac chambers are undergoing structural deformation throughout the cardiac cycle. Thus, this technique allows for an interactive micro-scale VR visualization of developmental cardiac morphology to enable high resolution simulation for both basic and clinical science

Occupational injury history and universal precautions awareness: a survey in Kabul hospital staff

<p>Abstract</p> <p>Background</p> <p>Health staff in Afghanistan may be at high risk of needle stick injury and occupational infection with blood borne pathogens, but we have not found any published or unpublished data.</p> <p>Methods</p> <p>Our aim was to measure the percentage of healthcare staff reporting sharps injuries in the preceding 12 months, and to explore what they knew about universal precautions. In five randomly selected government hospitals in Kabul a total of 950 staff participated in the study. Data were analyzed with Epi Info 3.</p> <p>Results</p> <p>Seventy three percent of staff (72.6%, 491/676) reported sharps injury in the preceding 12 months, with remarkably similar levels between hospitals and staff cadres in the 676 (71.1%) people responding. Most at risk were gynaecologist/obstetricians (96.1%) followed by surgeons (91.1%), nurses (80.2%), dentists (75.4%), midwives (62.0%), technicians (50.0%), and internist/paediatricians (47.5%). Of the injuries reported, the commonest were from hollow-bore needles (46.3%, n = 361/780), usually during recapping. Almost a quarter (27.9%) of respondents had not been vaccinated against hepatitis B. Basic knowledge about universal precautions were found insufficient across all hospitals and cadres.</p> <p>Conclusion</p> <p>Occupational health policies for universal precautions need to be implemented in Afghani hospitals. Staff vaccination against hepatitis B is recommended.</p

Prevalence of Concurrent Functional Vision and Hearing Impairment and Association With Dementia in Community-Dwelling Medicare Beneficiaries.

IMPORTANCE: Impairments in vision or hearing are common and have been independently linked to higher risk of dementia in older adults. There is a limited understanding of the prevalence of concurrent functional vision and hearing impairment (dual sensory impairment) and its contribution to dementia risk. OBJECTIVE: To examine the age-specific prevalence of functional dual sensory impairment among older adults, and to investigate the cross-sectional and 7-year longitudinal associations between functional dual sensory impairment and dementia. DESIGN, SETTING, AND PARTICIPANTS: This cohort study of 7562 older adults used data from the US National Health and Aging Trends Study (NHATS), a nationally representative cohort study of community-dwelling, Medicare beneficiaries aged 65 years and older in the US. Participants in the study with complete data on hearing, vision, and dementia were included in analysis. Data were collected between 2011 and 2018, and between March 2018 and May 2020. EXPOSURES: Self-reported functional sensory impairments (ie, no sensory impairment, functional vision impairment only, functional hearing impairment only, and functional dual sensory impairment). MAIN OUTCOMES AND MEASURES: Age-specific prevalence of functional sensory impairments was calculated. Generalized linear regression with a complementary log-log link and a discrete time proportional hazards model with a complementary log-log link were used to assess the cross-sectional and 7-year longitudinal hazard of dementia. RESULTS: Of 7562 participants, 3073 (40.7%) were ages 80 years or older and 4411 (58.3%) were women. Overall, 5.4% (95% CI, 4.7%-6.1%) of participants reported functional vision impairment only, 18.9% (95% CI, 18.9%-17.8%) reported functional hearing impairment only, and 3.1% (95% CI, 2.7%-3.5%) reported functional dual sensory impairment (prevalence estimates are weighted). Participants reporting sensory impairments were older (no impairment: age ≥90 years, 2.12% [95% CI, 1.79%-2.46%] vs functional dual sensory impairment: age ≥90 years, 20.06% [95% CI, 16.02%-24.10%]), had lower education (no impairment: <high school, 19.05% [95% CI, 17.27%-20.83%] vs functional dual sensory impairment: <high school, 46.15% [95% CI, 38.38%-53.92%]), and greater disease burden (eg, heart disease: no impairment, 15.30% [95% CI, 14.04%-16.55%] vs functional dual sensory impairment, 25.49% [95% CI, 19.96%-31.02%]). Compared with no impairment, functional vision impairment (adjusted hazard ratio [aHR], 1.89; 95% CI, 1.57-2.28), functional hearing impairment (aHR, 1.14; 95% CI, 1.00-1.31), and functional dual sensory impairment (aHR, 2.00; 95% CI, 1.57-2.53) were associated with a higher cross-sectional hazard of dementia. Over 7 years, functional vision impairment (aHR, 1.40; 95% CI, 1.12-1.74), functional hearing impairment (aHR, 1.09; 95% CI, 0.95-1.24), and functional dual sensory impairment (aHR, 1.50; 95% CI, 1.12-2.02) were associated with a higher hazard of incident dementia compared with no impairment. CONCLUSIONS AND RELEVANCE: In this cohort study of US Medicare beneficiaries, dual sensory impairment was prevalent in older adults and associated with increased risk of dementia. These findings suggest that sensory rehabilitative interventions for multiple impairments may be an additional resource in efforts to reduce dementia risk

Crimmigration and Refugees: Bridging Visas, Criminal Cancellations and ‘Living in the Community’ as Punishment and Deterrence

Australia’s status as the only state with a policy of mandatory indefinite detention of all unlawful non-citizens, including asylum seekers, who are within Australian territory is a fact that is both well-known and frequently cited. From its inception, mandatory immigration detention was touted as ‘the method of deterrence for those seeking asylum onshore’ and since then ‘mandatory detention has been at the forefront of a deterrence as control and control as deterrence discourse’2. The imagined subjects of deterrence are frequently asylum seekers presented as ‘bogus’ or as economic migrants, and the sites for control are Australia’s ‘immigration program’ and borders. While these dual factors have animated the implementation and continuation of the policy for over 25 years, the contemporary practice and enforcement of detention in Australia presents a much more complex picture
