Rehabilitation Modifications for a Patient with Parkinson’s Disease Following a Suspected Case of Gilbert’s Syndrome: A Case Study

The purpose of this case study was to assess the effects of core stabilization exercises, balance training, agility ladder step drills, fine motor, and dual-task training in the treatment of a high-functioning, 55-year-old, male patient with a history of Parkinson’s Disease and suspected Gilbert’s Syndrome. This treatment program delivered for 1 hour once per week over 4 weeks led to mild improvements in activity limitations with the most notable being able to button a shirt with decreased time and assistance. The patient also exhibited mild improvement in body structure/function impairments with decreased loss of balance as evident during tandem walking in the Functional Gait Assessment. This case report suggests that a multimodal physical therapy treatment approach can be effective in the treatment of a patient with Parkinson’s Disease and suspected Gilbert’s Syndrome.https://soar.usa.edu/casmsummer2019/1001/thumbnail.jp

The Health Benefits of Visual Art Activities in the Geriatric Population

Purpose: The purpose of this poster presentation is to assess the efficacy of visual art therapy on the physical and mental health of the geriatric population. Description: The potential impact of art therapy on cognition and dementia is a growing field of research in the rehabilitative world. Some researchers have found support for certain mediums, such as ceramic painting, while others have explored multimodal treatment programs that integrate art into physical activities. Combining physical activity with an arts and crafts program could posit a significant impact on ADL function and quality of life in older adults. As a growing list of ailments accompany aging, it would be of interest to explore the effects of visual art therapy on life satisfaction, cognitive status, ADLs, and levels of depression in older adults. Methods: A literature review was conducted on visual art activities and health in the geriatric population using the following search terms: art therapy, visual art, mental health, health, cognition, geriatric, and older adults. Five peer-reviewed studies that were published between 2016 and 2019 were selected for review. Conclusion: The current literature supports the inclusion of visual art therapy as treatment for older adults. Research shows that art therapy can decrease grief, mourning, negative emotions, and depression while promoting positive memories, socializing, language function and quality of life in older adults. Art therapy has also been correlated with positive effects on emotional status and cognitive status in patients with dementia. Summary of Use: This poster presentation reviews the benefits of implementing visual art therapy in geriatric rehabilitation in terms of both physical and mental health. Clinical Relevance: Visual art activities are low-intensity interventions that work to improve both gross motor and fine motor skills in the geriatric population. Art activities can specifically help address deficits of upper body strength, stability, proprioception, and tactile skills. In addition to physical improvements, participant engagement, mood, quality of life, and well-being are positively affected as well. Given the potential benefits, further research is needed to bolster support for the integration of visual art activities with traditional exercise.https://soar.usa.edu/casmspring2020/1001/thumbnail.jp

Phenotypic Detection of Extended Spectrum β-Lactamase and Metallo-β-Lactamase Produced by Escherichia Coli on Automated Teller Machines within Sokoto Metropolis, Nigeria

It is no longer a fallacy that environmental objects are grossly  contaminated by pathogenic microbes. ATMs especially which is used on daily basis by thousands of people have been reported to be potentialhabitat for these microbes. The worst-case scenario is the presence and ease of spread of Muti-Drug Resistant (MDR) and Extended Spectrum Beta Lactamase (ESBL) producing pathogens via these machines as a result of their huge patronage. The prevalence and fast spread of these MDR and ESBL producing strains constitute an emerging public health concern. This study was conducted to determine the prevalence of ESBL and MBL producing E. coli isolated on ATMs within Sokoto metropolis. A total of 194 isolates were obtained from the culture samples of 100 ATM swabs. The isolated E. coli were subjected to antimicrobial susceptibility tests using the modified Kirby Baeur disc diffusion method on six (6) commercial antimicrobial discs (Oxoid, UK): Ceftazidime (CTZ, 30μg), Cefotaxime (CTX, 30μg), Gentamycin (CN, 10μg), Augumentin(AMC, 30μg), Ciprofloxacin(CIP, 5μg) and Imipenem(IPM, 10μg). The isolates were further screened for ESBL production and phenotypic confirmatory test.Confirmation of MBL production was also performed using antibiotic discs containing two Carbapenems (Imipenem IPM, 10μg and Meropenem MEM, 10μg). The result was interpreted using CLSI guideline 2015. Proteus spp (43%) were the most frequently isolated bacteria, followed by Shigella spp (31%) and E. coli 31(16%). Drug Resistant (MDR) ESBL producing E. coli of 93.3% and 4% MBL producer was recorded. It can be concluded that MDR and ESBL producing Escherichia coli (E. coli) are the most prevalent species isolated and that the species isolated are more sensitive to Gentamycin, Ciprofloxacin and Imipenem.Keywords: ESBL, MDR, ATM and Susceptibility

Association between the plasma/whole blood lead ratio and history of spontaneous abortion: a nested cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Blood lead has been associated with an elevated risk of miscarriage. The plasmatic fraction of lead represents the toxicologically active fraction of lead. Women with a tendency to have a higher plasma/whole blood Pb ratio could tend towards an elevated risk of miscarriage due to a higher plasma Pb for a given whole blood Pb and would consequently have a history of spontaneous abortion.</p> <p>Methods</p> <p>We studied 207 pregnant Mexico City residents during the 1^sttrimester of pregnancy, originally recruited for two cohorts between 1997 and 2004. Criteria for inclusion in this study were having had at least one previous pregnancy, and having valid plasma and blood Pb measurements. Pb was measured in whole blood and plasma by inductively coupled plasma mass spectrometry using ultra-clean techniques. History of miscarriage in previous pregnancies was obtained by interview. The incidence rate of spontaneous abortion was defined as the proportion of previous pregnancies that resulted in miscarriage. Data were analyzed by means of Poisson regression models featuring the incidence rate of spontaneous abortion as the outcome and continuous or categorized plasma/blood Pb ratios as predictor variables. All models were adjusted for age and schooling. Additionally, logistic regression models featuring inclusion in the study sample as the outcome were fitted to assess potential selection bias.</p> <p>Results</p> <p>The mean number of miscarriages was 0.42 (range 0 to 4); mean Pb concentrations were 62.4 and 0.14 μg/L in whole blood and plasma respectively. Mean plasma/blood Pb ratio was 0.22%. We estimated that a 0.1% increment in the plasma/blood Pb ratio lead was associated to a 12% greater incidence of spontaneous abortion (p = 0.02). Women in the upper tertile of the plasma/blood Pb ratio had twice the incidence rate of those in the lower tertile (p = 0.02). Conditional on recruitment cohort, inclusion in the study sample was unrelated to observable characteristics such as number of abortions, number of pregnancies, blood Pb levels, age schooling, weight and height.</p> <p>Conclusion</p> <p>Women with a large plasma/whole blood Pb ratio may be at higher risk of miscarriage, which could be due to a greater availability of placental barrier-crossing Pb.</p

Impact of N on the atomic-scale Sb distribution in quaternary GaAsSbN-capped InAs quantum dots

The use of GaAsSbN capping layers on InAs/GaAs quantum dots (QDs) has recently been proposed for micro- and optoelectronic applications for their ability to independently tailor electron and hole confinement potentials. However, there is a lack of knowledge about the structural and compositional changes associated with the process of simultaneous Sb and N incorporation. In the present work, we have characterized using transmission electron microscopy techniques the effects of adding N in the GaAsSb/InAs/GaAs QD system. Firstly, strain maps of the regions away from the InAs QDs had revealed a huge reduction of the strain fields with the N incorporation but a higher inhomogeneity, which points to a composition modulation enhancement with the presence of Sb-rich and Sb-poor regions in the range of a few nanometers. On the other hand, the average strain in the QDs and surroundings is also similar in both cases. It could be explained by the accumulation of Sb above the QDs, compensating the tensile strain induced by the N incorporation together with an In-Ga intermixing inhibition. Indeed, compositional maps of column resolution from aberration-corrected Z-contrast images confirmed that the addition of N enhances the preferential deposition of Sb above the InAs QD, giving rise to an undulation of the growth front. As an outcome, the strong redshift in the photoluminescence spectrum of the GaAsSbN sample cannot be attributed only to the N-related reduction of the conduction band offset but also to an enhancement of the effect of Sb on the QD band structure

Anti-müllerian hormone is not associated with cardiometabolic risk factors in adolescent females

&lt;p&gt;Objectives: Epidemiological evidence for associations of Anti-Müllerian hormone (AMH) with cardiometabolic risk factors is lacking. Existing evidence comes from small studies in select adult populations, and findings are conflicting. We aimed to assess whether AMH is associated with cardiometabolic risk factors in a general population of adolescent females.&lt;/p&gt; &lt;p&gt;Methods: AMH, fasting insulin, glucose, HDLc, LDLc, triglycerides and C-reactive protein (CRP) were measured at a mean age 15.5 years in 1,308 female participants in the Avon Longitudinal Study of Parents and Children (ALSPAC). Multivariable linear regression was used to examine associations of AMH with these cardiometabolic outcomes.&lt;/p&gt; &lt;p&gt;Results: AMH values ranged from 0.16–35.84 ng/ml and median AMH was 3.57 ng/ml (IQR: 2.41, 5.49). For females classified as post-pubertal (n = 848) at the time of assessment median (IQR) AMH was 3.81 ng/ml (2.55, 5.82) compared with 3.25 ng/ml (2.23, 5.05) in those classed as early pubertal (n = 460, P≤0.001). After adjusting for birth weight, gestational age, pubertal stage, age, ethnicity, socioeconomic position, adiposity and use of hormonal contraceptives, there were no associations with any of the cardiometabolic outcomes. For example fasting insulin changed by 0% per doubling of AMH (95%CI: −3%,+2%) p = 0.70, with identical results if HOMA-IR was used. Results were similar after additional adjustment for smoking, physical activity and age at menarche, after exclusion of 3% of females with the highest AMH values, after excluding those that had not started menarche and after excluding those using hormonal contraceptives.&lt;/p&gt; &lt;p&gt;Conclusion: Our results suggest that in healthy adolescent females, AMH is not associated with cardiometabolic risk factors.&lt;/p&gt

High frequency of the IVS2-2A>G DNA sequence variation in SLC26A5, encoding the cochlear motor protein prestin, precludes its involvement in hereditary hearing loss

BACKGROUND: Cochlear outer hair cells change their length in response to variations in membrane potential. This capability, called electromotility, is believed to enable the sensitivity and frequency selectivity of the mammalian cochlea. Prestin is a transmembrane protein required for electromotility. Homozygous prestin knockout mice are profoundly hearing impaired. In humans, a single nucleotide change in SLC26A5, encoding prestin, has been reported in association with hearing loss. This DNA sequence variation, IVS2-2A>G, occurs in the exon 3 splice acceptor site and is expected to abolish splicing of exon 3. METHODS: To further explore the relationship between hearing loss and the IVS2-2A>G transition, and assess allele frequency, genomic DNA from hearing impaired and control subjects was analyzed by DNA sequencing. SLC26A5 genomic DNA sequences from human, chimp, rat, mouse, zebrafish and fruit fly were aligned and compared for evolutionary conservation of the exon 3 splice acceptor site. Alternative splice acceptor sites within intron 2 of human SLC26A5 were sought using a splice site prediction program from the Berkeley Drosophila Genome Project. RESULTS: The IVS2-2A>G variant was found in a heterozygous state in 4 of 74 hearing impaired subjects of Hispanic, Caucasian or uncertain ethnicity and 4 of 150 Hispanic or Caucasian controls (p = 0.45). The IVS2-2A>G variant was not found in 106 subjects of Asian or African American descent. No homozygous subjects were identified (n = 330). Sequence alignment of SLC26A5 orthologs demonstrated that the A nucleotide at position IVS2-2 is invariant among several eukaryotic species. Sequence analysis also revealed five potential alternative splice acceptor sites in intron 2 of human SLC26A5. CONCLUSION: These data suggest that the IVS2-2A>G variant may not occur more frequently in hearing impaired subjects than in controls. The identification of five potential alternative splice acceptor sites in intron 2 of human SLC26A5 suggests a potential mechanism by which expression of prestin might be maintained in cells carrying the SLC26A5 IVS2-2A>G DNA sequence variation. Additional studies are needed to evaluate the effect of the IVS2-2A>G transition on splicing of SLC26A5 transcripts and characterize the hearing status of individuals homozygous for the IVS2-2A>G variant

Antibodies against the Envelope Glycoprotein Promote Infectivity of Immature Dengue Virus Serotype 2

Cross-reactive dengue virus (DENV) antibodies directed against the envelope (E) and precursor membrane (prM) proteins are believed to contribute to the development of severe dengue disease by facilitating antibody-dependent enhancement of infection. We and others recently demonstrated that anti-prM antibodies render essentially non-infectious immature DENV infectious in Fcγ-receptor-expressing cells. Immature DENV particles are abundantly present in standard (st) virus preparations due to inefficient processing of prM to M during virus maturation. Structural analysis has revealed that the E protein is exposed in immature particles and this prompted us to investigate whether antibodies to E render immature particles infectious. To this end, we analyzed the enhancing properties of 27 anti-E antibodies directed against distinct structural domains. Of these, 23 bound to immature particles, and 15 enhanced infectivity of immature DENV in a furin-dependent manner. The significance of these findings was subsequently tested in vivo using the well-established West Nile virus (WNV) mouse model. Remarkably, mice injected with immature WNV opsonized with anti-E mAbs or immune serum produced a lethal infection in a dose-dependent manner, whereas in the absence of antibody immature WNV virions caused no morbidity or mortality. Furthermore, enhancement infection studies with standard (st) DENV preparations opsonized with anti-E mAbs in the presence or absence of furin inhibitor revealed that prM-containing particles present within st virus preparations contribute to antibody-dependent enhancement of infection. Taken together, our results support the notion that antibodies against the structural proteins prM and E both can promote pathogenesis by enhancing infectivity of prM-containing immature and partially mature flavivirus particles
