Abstract

Abstract The inner ear is the hub where hair cells (HCs) transduce sound, gravity, and head acceleration stimuli to the brain. Hearing and balance rely on mechanosensation, the fastest sensory signals transmitted to the brain. The mechanoelectrical transducer (MET) channel is the entryway for the sound-balance-brain interface, but the channel-complex composition is not entirely known. Here, we report that the mouse utilizes Piezo1 (Pz1) and Piezo2 (Pz2) isoforms as MET-complex components. The Pz channels, expressed in HC stereocilia, and cell lines are co-localized and co-assembled with MET complex partners. Mice expressing non-functional Pz1 and Pz2 at the ROSA26 locus have impaired auditory and vestibular traits that can only be explained if the Pzs are integral to the MET complex. We suggest that Pz subunits constitute part of the MET complex and that interactions with other MET complex components yield functional MET units to generate HC MET currents.

Abstract

Abstract Background Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary renal disorder and the fourth cause of death of end-stage renal disease. The disease has a prevalence of 1:400–1:1000 accounting for 10% of patients on dialysis. In most ADPKD patients, bilateral kidneys are similarly affected, with numerous fluid-filled cysts arising from different nephron segments. Only a few cases of ADPKD with ectopic unilateral multicystic kidney have been reported. It has been observed that the deterioration of their kidney function seemed to be quicker than their age- and sex-matched controls and siblings especially when the ectopic kidney is dysplastic. Case presentation We report a case of a 46-year-old Ghanaian male patient who presented with left flank pain and hematuria with high BP and deranged renal function. Abdominal ultrasonography showed both kidneys to be larger than normal and had multiple cysts of varying sizes with the right kidney located in the right iliac fossa. Follow up Abdominopelvic computer tomographic scan (CT–Scan) without contrast showed enlarged kidneys with the renal parenchyma replaced by innumerable cyst of varying sizes. The right kidney was ectopically located in the right aspect of the pelvis. A diagnosis of ADPKD with right pelvic ectopic multicystic kidney was made. He was put on antihypertensives, analgesia for the left flank pain and to have follow up at the urology and nephrology departments. Conclusion In most ADPKD patients, bilateral kidneys are similarly affected. Only a few cases of ADPKD with ectopic unilateral multicystic kidney have been reported. It has been observed that the deterioration of their kidney function seemed to be quicker than their age- and sex-matched controls and siblings especially when the ectopic kidney is dysplastic.

Abstract

Intracellular pH (pHi) plays critical roles in the regulation of cardiac function. Methods and techniques for cardiac pHi measurement have continued to evolve since early 1960s. Fluorescent microscopy is the most recently developed technique with several advantages over other techniques including higher spatial and temporal resolutions, and feasibility for contracting cell measurement. Here, we describe detailed methods for mouse cardiomyocyte isolation, and simultaneous measurement and quantification of pHi and sarcomere length in contracting cardiomyocytes. For complete details on the use and execution of this protocol, please refer to Lyu et al. (2022).

63. The Psychosocial Impact of Rare Diseases among Children and Adolescents Attending Mainstream Schools in Western Australia

Author

Adama, E. A., Arabiat, D., Foster, M. J., Afrifa-Yamoah, E., Runions, K., Vithiatharan, R., and Lin, A.

Abstract

Living with a long-term medical condition is associated with heightened risk for mental health and psychosocial difficulties, but further research is required on this risk for children and adolescents with a rare disease in the educational setting. The aim of this study is to describe parents' perceptions of the psychosocial impact of rare diseases on their school-aged children in Western Australia. A cross-sectional survey of 41 parents of school-aged children and adolescents diagnosed with a rare disease completed an online questionnaire. Questions related to their perceptions of health-related stigma, bullying, social competencies and mental health difficulties faced by their child. Results showed that stigmatisation was experienced by 75.6% of participants, and almost half (46.4%) reported their child was bullied. In this sample, parents reported high sensory (vision and hearing) abilities, but low to moderate self-care competence in relation to social activities and peer relations. Almost half of the respondents (43.9%) reported mental health difficulties among their children. Children and adolescents with a rare disease have unique psychological and social issues. These findings highlight the need for greater efforts to meet the diverse psychosocial, physical and emotional needs of children diagnosed with a rare disease who attend mainstream schools in Western Australia.

64. COVID-19 and Alternative Assessments in Higher Education: Implications for Academic Integrity among Nursing and Social Science Students

Author

Adama, Esther Abena, Graf, Amanda, Adusei-Asante, Kwadwo, and Afrifa-Yamoah, Ebenezer

Abstract

Background: COVID-19 and its associated restrictions called for innovations in higher education teaching and learning space with many universities resorting to online teaching and alternative assessments. However, little has been done to understand the academic integrity implications in alternative online and non-invigilated assessments. Aim: This study explored the perceptions of higher education students regarding academic integrity in alternative assessments. Methods: Cross-sectional mixed method design following the parallel convergent approach was utilised in this study. A convenience sample of 380 undergraduate and postgraduate nursing and social science students completed an online survey on academic integrity behaviours associated with alternative assessments. Results: High risk (31.7%) of academic misconduct was perceived among young people (18-24 years old). Collusion was common among nursing students (24.5%) and cheating likely to occur in assessments with longer duration--between 2 and 4 hours (18.8%) and between 1 and 2 weeks (46%). Qualitative data resulted in 274 findings and three themes--(i) impossible to cheat; (ii) easy to cheat and (iii) understanding the consequence of cheating. Suggestions for preserving academic integrity in alternative assessments were also made from the qualitative data. Conclusion: Like other forms of traditional assessments, alternative assessments have increased risk of breach of academic integrity; however, with the right strategies, they could serve as effective means of assessing learning outcomes.

65. Towards a Framework for the Promotion of Business Management Graduate Employability: An Extended CareerEDGE Model

Author

Yawson, David Eshun and Yamoah, Fred Amofa

Abstract

This paper builds on the dominant employability model by Dacre Pool and Sewell -- CareerEDGE model by developing an extended CareerEDGE model for embedding, evaluating and monitoring employability skills relevant to undergraduate students. Drawing on the current literature on employability, the 'Extended CareerEDGE Model' is developed by formulating a measurement framework. Elements of the extended model and framework are discussed and their inclusion is justified on the basis of existing research. The model extends the CareerEDGE model by facilitating the inclusion of entrepreneurship knowledge and skills as student entrepreneurial orientation to engender the requisite entrepreneurial mindset to address the need for intrapreneurial and entrepreneurial skills required to operate in the business environment. The study validates the Extended CareerEDGE Model of graduate employability with responses from 947 students engaged in a core employability-embedded business school undergraduate programme. The study confirms a positive relationship between student entrepreneurial orientation with employability reflection and evaluation. Also, the results confirm a positive relationship between Students' Achievement Orientation with Career Development Learning. A similar positive relationship was established between Students' Achievement Orientation and Degree Subject Knowledge as well as the acquisition of Generic Skills. Additionally, student Learning Orientation positively influences Career Development Learning, Degree Subject Knowledge and Generic Skills acquisition. The extended CareerEDGE model succinctly informs the planning of programmes and structured interventions on employability essentials for students, administrators and academics.

66. Understanding Utility Essentials of E-Learning Management Systems in Higher Education: A Multi-Generational Cohort Perspective

Author

Yawson, David and Yamoah, Fred Amofa

Abstract

This research aimed to explore the nuances of utility in components of e-learning systems by using a multi-generational undergraduate business school cohort programme and an e-learning utility-satisfaction evaluation model. Our empirical research demonstrates differences between the three generations for the utility of all the variables of the e-learning systems components, with varying differences in the relationships between Generations X, Y and Z. Furthermore, we show course development, learner support and user characteristics influence results demonstrability which has a high influence on overall satisfaction. We established nuances in the learning utility essentials in courses on e-learning systems for multi-generational cohorts; revealed the utility of learner support as a key differentiator and developed a model on utility-satisfaction with reasonable explanatory and predictive power. The model possesses the dual advantages of fewer constituent items and the connective capability to link utility to satisfaction to enable e-learning systems evaluation and ease of identifying areas for improvement in e-learning course delivery.

Abstract

Abstract Background Vernal Keratoconjunctivitis (VKC) has been determined to be highly prevalent in countries within the tropical climate region. However, little evidence from studies conducted within this region has been put forward to support this claim. Aim To determine the prevalence and risk factors of VKC among a Ghanaian clinical cohort. Methods A 3‐year case‐control study was conducted in a tertiary eye care institution, and medical records of patients who had been diagnosed of VKC between 2018 and 2021 were reviewed. Results Medical records of 3800 patients were reviewed. Some 359 cases of VKC were identified, with a population prevalence rate of 9.45 %. Males comprised 57.1 % of the population with VKC, with a male‐to‐female ratio of 1.33 : 1. The disease was more prevalent (40.8%) in children (≤17 years), and the overall odds of incidence decreased by 10% for a unit increase in age. Age and sex‐adjusted models revealed significant positive associations between Keratoconus [aOR = 40.760, 95% CI –5.948 to 339.937], Rhinitis [cOR = 5.183, 95% CI –2.074 to 12.022] and VKC. However, the incidence of VKC was relatively less expressive among pterygium cases [cOR = 0.315, 95% CI –0.077 to 0.846]. Conclusion VKC is highly prevalent among children and is often associated with comorbidities of atopic origin that exacerbate the impact of the disease among this vulnerable population. It is imperative that clinicians provide holistic care for children with VKC.

Abstract

Dielectrics with low loss at microwave frequencies are imperative for high-coherence solid-state quantum computing platforms. We study the dielectric loss of hexagonal boron nitride (hBN) thin films in the microwave regime by measuring the quality factor of parallel-plate capacitors (PPCs) made of NbSe$_{2}$-hBN-NbSe$_{2}$ heterostructures integrated into superconducting circuits. The extracted microwave loss tangent of hBN is bounded to be at most in the mid-10$^{-6}$ range in the low temperature, single-photon regime. We integrate hBN PPCs with aluminum Josephson junctions to realize transmon qubits with coherence times reaching 25 $\mu$s, consistent with the hBN loss tangent inferred from resonator measurements. The hBN PPC reduces the qubit feature size by approximately two-orders of magnitude compared to conventional all-aluminum coplanar transmons. Our results establish hBN as a promising dielectric for building high-coherence quantum circuits with substantially reduced footprint and, with a high energy participation that helps to reduce unwanted qubit cross-talk.

Abstract

Abstract Background Gastrointestinal Stromal Tumour is a rare but potentially curable tumour of the gastrointestinal tract accounting for up to 1% of all gastrointestinal tumours. The discovery of Imatinib mesylate, a novel tyrosine kinase inhibitor has improved the chances even for unresectable, recurrent, or metastatic diseases. Methods This study sought to document the clinical and pathological characteristics of GISTs from two tertiary hospitals in Ghana that have undergone immunohistochemistry confirmation between 2014 and 2021. Results The median age of the subjects was 50 years with most of them (28.0%) being above 61 years. There were more females than males (64.0% vs. 36.0%). Abdominal mass and abdominal pain made up the majority of the clinical presentations. The majority of the subjects had partial gastrectomy (32.0%) which was followed by wedge resection (28.0%). Appendectomy and sleeve gastrectomy were the least performed procedures (8% each). Four of the 25 patients (16.0%) had resections of involved contiguous organs done with splenectomy being the most common procedure. The majority of GISTs were found in the stomach (68.0%) followed by the appendix (12.0%) and small bowel (12.0%). Gastrointestinal bleeding (55.8%) and abdominal pain (38.5%) were the most reported symptoms. Free resection margins were observed in 84.0% of the subjects and only 3/25 (12.0%) experienced tumour recurrence. Conclusion GIST is a potentially curable tumour that once was obscure but currently gaining popularity. Surgical resection offers the hope of a cure for localized disease while targeted therapies is a viable option for recurrent, metastatic, or unresectable tumours.

Abstract

BackgroundLong QT syndrome (LQTS) is a hereditary disease that predisposes patients to life-threatening cardiac arrhythmias and sudden cardiac death. Our previous study of the human ether-à-go-go related gene (hERG)-encoded K+ channel (Kv11.1) supports an association between hERG and RING finger protein 207 (RNF207) variants in aggravating the onset and severity of LQTS, specifically T613M hERG (hERGT613M) and RNF207 frameshift (RNF207G603fs) mutations. However, the underlying mechanistic underpinning remains unknown.ObjectiveThe purpose of the present study was to test the role of RNF207 in the function of hERG-encoded K+ channel subunits.MethodsWhole-cell patch-clamp experiments were performed in human embryonic kidney (HEK 293) cells and human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) together with immunofluorescent confocal and high resolution microscopy, auto-ubiquitinylation assays, and co-immunoprecipitation experiments to test the functional interactions between hERG and RNF207.ResultsHere, we demonstrated that RNF207 serves as an E3 ubiquitin ligase and targets misfolded hERGT613M proteins for degradation. RNF207G603fs exhibits decreased activity and hinders the normal degradation pathway; this increases the levels of hERGT613M subunits and their dominant-negative effect on the wild-type subunits, ultimately resulting in decreased current density. Similar findings are shown for hERGA614V, a known dominant-negative mutant subunit. Finally, the presence of RNF207G603fs with hERGT613M results in significantly prolonged action potential durations and reduced hERG current in human-induced pluripotent stem cell-derived cardiomyocytes.ConclusionOur study establishes RNF207 as an interacting protein serving as a ubiquitin ligase for hERG-encoded K+ channel subunits. Normal function of RNF207 is critical for the quality control of hERG subunits and consequently cardiac repolarization. Moreover, our study provides evidence for protein quality control as a new paradigm in life-threatening cardiac arrhythmias in patients with LQTS.

Abstract

Among the features of cisplatin chemotherapy-induced peripheral neuropathy are chronic pain and innocuous mechanical hypersensitivity. The complete etiology of the latter remains unknown. Here, we show that cisplatin targets a heterogeneous population of tyrosine hydroxylase-positive (TH+) primary afferent dorsal root ganglion neurons (DRGNs) in mice, determined using single-cell transcriptome and electrophysiological analyses. TH+ DRGNs regulate innocuous mechanical sensation through C-low threshold mechanoreceptors. A differential assessment of wild-type and vitamin E deficient TH+ DRGNs revealed heterogeneity and specific functional phenotypes. The TH+ DRGNs comprise; fast-adapting eliciting one action potential (AP; 1-AP), moderately-adapting (≥2-APs), in responses to square-pulse current injection, and spontaneously active (SA). Cisplatin increased the input resistance and AP frequency but reduced the temporal coding feature of 1-AP and ≥2-APs neurons. By contrast, cisplatin has no measurable effect on the SA neurons. Vitamin E reduced the cisplatin-mediated increased excitability but did not improve the TH+ neuron temporal coding properties. Cisplatin mediates its effect by targeting outward K+ current, likely carried through K2P18.1 (Kcnk18), discovered through the differential transcriptome studies and heterologous expression. Studies show a potential new cellular target for chemotherapy-induced peripheral neuropathy and implicate the possible neuroprotective effects of vitamin E in cisplatin chemotherapy.

Abstract

The mammalian heart beats incessantly with rhythmic mechanical activities generating acids that need to be buffered to maintain a stable intracellular pH (pHi) for normal cardiac function. Even though spatial pHi non-uniformity in cardiomyocytes has been documented, it remains unknown how pHi is regulated to match the dynamic cardiac contractions. Here, we demonstrated beat-to-beat intracellular acidification, termed pHi transients, in synchrony with cardiomyocyte contractions. The pHi transients are regulated by pacing rate, Cl-/HCO3 - transporters, pHi buffering capacity, and β-adrenergic signaling. Mitochondrial electron-transport chain inhibition attenuates the pHi transients, implicating mitochondrial activity in sculpting the pHi regulation. The pHi transients provide dynamic alterations of H+ transport required for ATP synthesis, and a decrease in pHi may serve as a negative feedback to cardiac contractions. Current findings dovetail with the prevailing three known dynamic systems, namely electrical, Ca2+, and mechanical systems, and may reveal broader features of pHi handling in excitable cells.

Abstract

Prestin (Slc26a5) is a motor protein previously considered to be expressed exclusively in outer hair cells (OHCs) of the inner ear. However, we recently identified the functional expression of prestin in the heart. Nonlinear capacitance (NLC) measurement in OHCs is used to evaluate the signature function of prestin, which exhibits membrane potential-dependent conformational changes. Here, we describe detailed recording techniques and quantification methods for NLC to evaluate the prestin function in mouse ventricular myocytes. For complete details on the use and execution of this protocol, please refer to Zhang et al. (2021).

Abstract

BackgroundDisparities in prostate cancer-specific mortality (PCSM) between African American and non-Hispanic White (White) patients have been attributed to biological and systemic factors. We evaluated drivers of these disparities in the Surveillance, Epidemiology, and End Results (SEER) national registry and an equal-access system, the Veterans Health Administration (VHA).MethodsWe identified African American and White patients diagnosed with prostate cancer between 2004 and 2015 in SEER (n = 311 691) and the VHA (n = 90 749). We analyzed the association between race and metastatic disease at presentation using multivariable logistic regression adjusting for sociodemographic factors and PCSM using sequential competing-risks regression adjusting for disease and sociodemographic factors.ResultsThe median follow-up was 5.3 years in SEER and 4.7 years in the VHA. African American men were more likely than White men to present with metastatic disease in SEER (adjusted odds ratio = 1.23, 95% confidence interval [CI] = 1.17 to 1.30) but not in the VHA (adjusted odds ratio = 1.07, 95% CI = 0.98 to 1.17). African American vs White race was associated with an increased risk of PCSM in SEER (subdistribution hazard ratio [SHR] = 1.32, 95% CI = 1.10 to 1.60) but not in the VHA (SHR = 1.00, 95% CI = 0.93 to 1.08). Adjusting for disease extent, prostate-specific antigen, and Gleason score eliminated the association between race and PCSM in SEER (aSHR = 1.04, 95% CI = 0.93 to 1.16).ConclusionsRacial disparities in PCSM were present in a nationally representative registry but not in an equal-access health-care system, because of differences in advanced disease at presentation. Strategies to increase health-care access may bridge the racial disparity in outcomes. Longer follow-up is needed to fully assess mortality outcomes.

Abstract

Abstract Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD) are two neurodegenerative disorders that share genetic causes and pathogenic mechanisms. The critical genetic players of ALS and FTD are the TARDBP, FUS and C9orf72 genes, whose protein products, TDP-43, FUS and the C9orf72-dipeptide repeat proteins, accumulate in form of cytoplasmic inclusions. The majority of the studies focus on the understanding of how cells control TDP-43 and FUS aggregation in the cytoplasm, overlooking how dysfunctions occurring at the nuclear level may influence the maintenance of protein solubility outside of the nucleus. However, protein quality control (PQC) systems that maintain protein homeostasis comprise a cytoplasmic and a nuclear arm that are interconnected and share key players. It is thus conceivable that impairment of the nuclear arm of the PQC may have a negative impact on the cytoplasmic arm of the PQC, contributing to the formation of the cytoplasmic pathological inclusions. Here we focused on two stress-inducible condensates that act as transient deposition sites for misfolding-prone proteins: Promyelocytic leukemia protein (PML) nuclear bodies (PML-NBs) and cytoplasmic stress granules (SGs). Upon stress, PML-NBs compartmentalize misfolded proteins, including defective ribosomal products (DRiPs), and recruit chaperones and proteasomes to promote their nuclear clearance. SGs transiently sequester aggregation-prone RNA-binding proteins linked to ALS-FTD and mRNAs to attenuate their translation. We report that PML assembly is impaired in the human brain and spinal cord of familial C9orf72 and FUS ALS-FTD cases. We also show that defective PML-NB assembly impairs the compartmentalization of DRiPs in the nucleus, leading to their accumulation inside cytoplasmic SGs, negatively influencing SG dynamics. Although it is currently unclear what causes the decrease of PML-NBs in ALS-FTD, our data highlight the existence of a cross-talk between the cytoplasmic and nuclear PQC systems, whose alteration can contribute to SG accumulation and cytoplasmic protein aggregation in ALS-FTD.

Ghanaian women predominantly undergo opportunistic Pap smear screening for cervical cancer. Numerous studies have documented differences in the sociodemographic traits of participants undergoing Pap smear testing or screening, which correlates with their screening habits. This study aims to assess sociodemographic variables, including others that determine Pap test utilization at a single center in Ghana.Methods: A single-center survey was conducted by extracting data from the records of women who walked in for Pap smear testing. A telephone survey was also conducted among these women to document their barriers to utilizing the center. For data analysis, descriptive statistics and chi-square were utilized.Results: A total of 197 participants’ records were retrieved for the study. Most participants were market women (69.4%) and uneducated (71.4%). Their Pap smear screening records indicate that the majority (86%) had no history of cervical cancer screening, and only 3% tested positive for Pap smear test. Educational level, occupation and family history of cancer significantly correlated with participants’ Pap smear history (p< 0.05). However, most sociodemographic factors were not significant with the Pap test results of the participants (p> 0.05). The perceived barrier identified by most participants was the need for more information (67.40%) on the test.Conclusion: This study revealed that sociodemographic and gynaecological factors do not correlate with Pap test results. However, education level, occupation, and family history of cancer were significantly associated with the history of Pap smear uptake. The most significant barrier hindering Pap smear services was the need for more information.Keywords: pap smear, cervical cancer, sociodemographic factors, gynaecological factors, screening, women, Ghana
