Acknowledging the risk of suicidal ideation, depression, and anxiety in PAs.

ABSTRACT: The prevalence of suicidal ideation is unknown and limited information exists about depression and anxiety among physician associates/assistants (PAs). We set out to understand the degree of depression, anxiety, and suicidal ideation in PAs and PA students. In total, 728 PAs and 322 PA students took an online survey. Risk of depression and anxiety were present at higher levels in PA students compared with employed PAs. PA students indicated higher levels of suicidal ideation compared with clinically active PAs. One-third of those with suicidal ideation did not reveal it to anyone; among those who did, 16.2% feared the results of disclosure. This study establishes that PAs and PA students are at risk for suicidal ideation and often bypass help. The COVID-19 pandemic may have led to elevated rates of emotional distress, and longitudinal studies are needed to understand the basis for such ideation and if it is transitory.

PAs' skills in providing vision and ocular care.

OBJECTIVE: To evaluate characteristics, training, and self-reported skills and abilities in vision and ocular care among PAs not specializing in ophthalmology. METHODS: A survey on PA practice was administered to 5,763 randomly selected US-based PAs, and 537 respondents who completed the survey were invited to complete a separate vision and ocular care survey. Of those respondents, 382 completed the vision and ocular care survey. RESULTS: Among respondents, 23% of PAs were involved in eyecare by providing patient information, answering questions, and initiating discussions about vision care and ocular health more than once per month. More than 77% received vision and ocular care training in and/or outside PA training. PAs involved in eyecare had significantly greater odds of reporting higher desired and current skill and ability levels compared with PAs not involved in eyecare, in six of eight vision and ocular care domains. CONCLUSIONS: PAs who do not practice in ophthalmology provide vision and ocular care but have varying amounts of training and desire higher skill and ability levels. Ophthalmologists and PA institutions may develop vision and ocular care training for PA schools and continuing medical education.

Cerebrospinal fluid leaks secondary to dural tears: a review of etiology, clinical evaluation, and management.

OBJECTIVE: Damage to the dura mater often occurs in trauma cases of the head and spine, surgical procedures, lumbar punctures, and meningeal diseases. The resulting damage from dural tears, or durotomy, causes cerebrospinal fluid (CSF) to leak out into the surrounding space. The CSF leak induces intracranial hypotension, which can clinically present with a range of symptoms not limited to positional headaches which can confound accurate diagnosis. Current methods of evaluation and management of dural tears are discussed herewith, as well as the present understanding of its etiology, which may be classified as related to surgery, procedure, trauma, or connective tissue disorder. METHODS: We piloted a MEDLINE® database search of literature, with emphasis on the previous five years, combining keywords such as "cerebrospinal fluid leak," "surgery," "procedure," and "trauma" to yield original research articles and case reports for building a clinical profile. RESULTS: Patients with suspected dural tears should be evaluated based on criteria set by the International Headache Society, radiological findings, and a differential diagnosis to accurately identify the tear and its potential secondary complications. Afflicted patients may be treated promptly with epidural blood patches, epidural infusions, epidural fibrin glue, or surgical repair. At this time, epidural blood patches are the first line of treatment. Dural tears can be prevented to an extent by utilizing minimally invasive techniques and certain positions for lumbar puncture. Surgical, trauma, lumbar puncture, and epidural injection patients should be observed very carefully for dural tears and CSF leaks as the presenting clinical manifestations can be highly individualized and misguiding. CONCLUSION: Because studies have demonstrated a high frequency of dural tears, particularly in spinal surgery patients, there is a need for prospective studies so that clinicians can develop an elaborate prevention strategy and response to avoid serious, unseen complications.

Reasons PAs leave their jobs.

PURPOSE: Employee turnover is an important indicator that carries a heavy financial cost for healthcare organizations. Although previous research has highlighted some factors associated with turnover, the reasons physician assistants (PAs) leave their jobs are not fully understood. This study aimed to determine the most common reasons behind PA turnover. METHODS: In 2019, the American Academy of PAs (AAPA) distributed a survey to all PAs with an eligible email address. The survey included a question asking respondents if they had left or changed their job in the past year. Respondents answering this question in the affirmative were asked a follow-up multiple-choice question to determine the reason behind this change. RESULTS: A total of 13,088 PAs responded to the AAPA salary survey; of these, 1,261 reported leaving a job within the past year. The most common reasons provided for leaving a job were: better work/life balance (n = 209, 16.8%), moved (n = 208, 16.7%), better management/leadership/environment (reasons related to toxic/abusive environment) (n = 170, 13.6%), and better compensation/benefits (n = 148, 11.9%). CONCLUSION: Employers should focus on common reasons for turnover that can be reasonably addressed. Of the top three reasons behind PA turnover, those related to toxic/abusive work environments may be the most practical and important to address.

Depression, burnout, and professional outcomes among PAs.

OBJECTIVE: This study examined the effect of depression and burnout on PA professional fulfillment and medical errors. METHODS: Eight hundred eighty PAs completed an online survey containing the Professional Fulfillment Index, PHQ-2, GAD-7, and demographic questions. Two serial mediation models examined the relationship between depression, burnout, and professional outcomes. RESULTS: Burnout fully mediated the relationship between depression and outcomes in both models and the present research indicates that burnout plays a stronger role in job satisfaction than symptoms of depression. CONCLUSIONS: Understanding the underpinnings of professional satisfaction may mitigate clinician turnover, which in turn may lead to cost savings for the organization, better resilience and mental health for clinicians, and potentially better patient outcomes.

Epitope-Binding Characteristics for Risk versus Protective DRB1 Alleles for Visceral Leishmaniasis.

HLA-DRB1 is the major genetic risk factor for visceral leishmaniasis (VL). We used SNP2HLA to impute HLA-DRB1 alleles and SNPTEST to carry out association analyses in 889 human cases and 977 controls from India. NetMHCIIpan 2.1 was used to map epitopes and binding affinities across 49 Leishmania vaccine candidates, as well as across peptide epitopes captured from dendritic cells treated with crude Leishmania Ag and identified using mass spectrometry and alignment to amino acid sequences of a reference Leishmania genome. Cytokines were measured in peptide-stimulated whole blood from 26 cured VL cases and eight endemic healthy controls. HLA-DRB1*1501 and DRB1*1404/DRB1*1301 were the most significant protective and risk alleles, respectively, with specific residues at aa positions 11 and 13 unique to protective alleles. We observed greater peptide promiscuity in sequence motifs for 9-mer core epitopes predicted to bind to risk (*1404/*1301) compared with protective (*1501) DRB1 alleles. There was a higher frequency of basic amino acids in DRB1*1404/*1301-specific epitopes compared with hydrophobic and polar amino acids in DRB1*1501-specific epitopes at anchor residues pocket 4 and pocket 6, which interact with residues at DRB1 positions 11 and 13. Cured VL patients made variable, but robust, IFN-γ, TNF, and IL-10 responses to 20-mer peptides based on captured epitopes, with peptides based on DRB1*1501-captured epitopes resulting in a higher proportion (odds ratio 2.23, 95% confidence interval 1.17-4.25, p = 0.017) of patients with IFN-γ/IL-10 ratios > 2-fold compared with peptides based on DRB1*1301-captured epitopes. Our data provide insight into the molecular mechanisms underpinning the association of HLA-DRB1 alleles with risk versus protection in VL in humans.

Revisiting the pineal gland: a review of calcification, masses, precocious puberty, and melatonin functions.

Introduction: The pineal gland, an endocrine organ of the posterior cranial fossa famously involved in sleep and wakefulness, has continually been a topic of scientific advancement and curiosity. Methods: We review present an up-to-date review including the anatomy, embryology, and physiology of the pineal gland and its ability to secrete hormones including melatonin, pathophysiology of pineal gland tumors, cysts, and calcifications, their clinical presentation including their association with parkinsonism and precocious puberty, and various treatment approaches. Results: Exploring the biochemistry of melatonin, various calcification morphologies, and pineal tumors may uncover a wider role and the exhaustive case study consolidation allows clinicians to carefully review the literature and aid their treatment approaches. Conclusion: It is imperative that clinicians and diagnosticians are able to distinguish manifestations of an overlooked gland.

Reexamining the persisting wage gap between male and female PAs.

OBJECTIVE: To determine the magnitude of any difference in total compensation between male and female physician assistants (PAs) after controlling for personal and workplace factors related to compensation. METHODS: Using data from the 2019 AAPA Salary Survey, the authors conducted a sequential regression analysis to examine the relationship between a variety of personal and practice demographics and total compensation. RESULTS: After controlling for compensation-related factors, a wage gap between male and female PAs persisted: female PAs were paid almost $0.93 for every $1 male PAs were paid in the first year of work ($9,010 less). This wage gap widened by $201 for every year of work experience. CONCLUSIONS: A wage gap between male and female PAs persists even after including all compensation types and controlling for compensation-related factors that may differ between male and female PAs. Proposed policy implications could begin to mitigate the gap.

Cat-to-Human Transmission of Mycobacterium bovis, United Kingdom.

Human infection with Mycobacterium bovis is reported infrequently in the United Kingdom. Most cases involve previous consumption of unpasteurized milk. We report a rare occurrence of 2 incidents of cat-to-human transmission of M. bovis during a cluster of infection in cats.

Current understanding of tumor lysis syndrome.

Tumor lysis syndrome (TLS) is an oncologic emergency from the intracellular release of material in lysing malignant cells. The earlier it is treated, the less likely it is to be harmful to an individual and spread through the body. Common complications of TLS include arrhythmias, which are caused by hypocalcemia or hyperkalemia, renal failures due to hyperuricemia or hyperphosphatemia, and seizures. Furthermore, the risk to develop TLS varies widely based on several factors including factors that are related to disease, the patient, and the treatment of the patient. Laboratory data can be used to gauge the severity of TLS based on patient serum levels for specific markers. On the contrary, evidence of TLS via radiological imaging and electrocardiogram findings has been a limited way to evaluate TLS, indicating the need for further research in this area. Common trends of treatment have also been seen in the past several years, evident by case studies seen in the following literature review.

Neurological and neuropsychiatric manifestations of porphyria.

Porphyrias are inherited disorders of the heme biosynthetic pathway, usually characterized by dermatological changes due to the accumulation of byproducts in the pathway. Select porphyrias also affect the nervous system, namely hereditary coproporphyria, acute intermittent porphyria and variegate porphyria. Complications include paralysis, hyponatremia which can risk central pontine myelinolysis, seizures and coma. Neurological complications usually result from severe episodes of acute attacks. Acute attacks may also elicit neuropsychiatric symptoms such as confusion, hallucinations, anxiety and psychosis. However, these manifestations are generally self-limiting. Due to the generally low incidence of porphyria and full knowledge the associated neurological and psychiatric manifestations, we review the relevant porphyrias along with their clinical manifestations, evaluation, and management to raise its awareness in the clinical picture and to prevent misdiagnosis. Porphyria should be considered within the differential diagnosis for unexplained neurological symptoms.

PAs are a solution to the growing need for clinicians to treat an aging population.

OBJECTIVE: To elucidate the types of patients cared for by physician assistants (PAs), specifically older adults and those with complex medical conditions. METHODS: A nationwide survey was sent to PAs asking about their practice demographics, including the complexity of their patients and the types of treatment they provide; 676 responded. RESULTS: Less than 2% of PAs specialize in geriatrics but 92.1% of PAs see patients over age 65 years. Most PAs see patients with conditions associated with aging, including hypertension (85.8%) and osteoarthritis (82.1%) as well as those with three or more comorbidities (54.8%) or who are medically complex (52.8%). CONCLUSIONS: Although few PAs work exclusively in geriatrics, most PAs are providing medical care for older adults and patients with complex healthcare needs. PAs should be considered to fill healthcare needs that will continue to exist when caring for this patient population.

Neuro-urological sequelae of lumbar spinal stenosis.

PURPOSE: Lumbar spinal stenosis is characterized by the narrowing of the spinal canal, which subsequently induces impingement of neural elements in the lumbar spine. Thus, symptoms of lumbar spinal stenosis are typically associated with damage to those neural elements. Herewith, we target the genitourinary symptoms of lumbar spinal stenosis and the importance of differentiating these symptoms from other genitourinary pathologies, namely benign prostatic hyperplasia. MATERIALS AND METHODS: MeSH and keywords relevant to lumbar spinal stenosis and the organs of the urinary tract were used to a guide a literature search on MEDLINE. RESULTS: Bladder dysfunction, lower urinary tract symptoms (e.g. urinary incontinence, detrusor overactivity and underactivity, as well as frequent urinary tract infections), renal osteodystrophy and sexual dysfunction (e.g. erectile dysfunction and priapism) are implicated in lumbar spinal stenosis. CONCLUSIONS: It is imperative for urologists to conduct a thorough history and physical examination so that they will not misdiagnose secondary genitourinary manifestations of lumbar spinal stenosis as primary problems or misunderstand secondary problems. Urological consultations are also integral to prioritizing patients with the highest risk of bladder damage for corrective spinal surgery.

Physician assistants in urgent care.

OBJECTIVE: To describe the characteristics of physician assistants (PAs) who practice urgent care. METHODS: Data from national surveys conducted by the American Academy of PAs (AAPA) between 1998 and 2016 were analyzed, comparing PAs who practice in urgent care, emergency medicine, and all other specialties. RESULTS: The percentage of PAs who work in an urgent care setting has nearly doubled in the last 10 years. PAs who work in urgent care see more patients and perform more minor surgical procedures than those in emergency medicine. They are less likely to be newly graduated PAs than those in emergency medicine. PAs in urgent care are less likely than other PAs to consult a physician about their patients in real time. CONCLUSION: The number of PAs practicing urgent care is increasing. More research is needed to further characterize PA practice in this specialty.

Burnout, job satisfaction, and stress levels of PAs.

OBJECTIVE: The main goal of this study was to assess burnout, job satisfaction, and stress to gain insight into the work lives of female and male PAs. METHODS: Data were obtained from the 2016 American Academy of PAs salary survey. Descriptive statistics were used to assess questions related to burnout, happiness, and stress and to compare responses by sex. RESULTS: Analysis revealed that, in general, PAs experience modest levels of burnout but are happy at work. More than half (55.6%) rated spending too many hours at work as an important contributor to stress. A higher percentage of female PAs than male PAs (32.2% versus 25.6%) have quit a job due to stress. CONCLUSIONS: Overall, PAs rate aspects of work life favorably. Further research on factors that contribute to the PA work experience may help inform interventions aimed at improving job satisfaction among healthcare professionals.

Understanding the role of advanced practice providers in oncology in the United States.

PURPOSE: Advanced practice providers (APPs, which include NPs and physician assistants [PAs]) are integral members of oncology teams. This study aims first to identify all APPs in oncology and, second, to understand personal and practice characteristics (including compensation) of those APPs. METHODS: We identified APPs who practice oncology from membership and claims data. We surveyed 3,055 APPs about their roles in clinical care. RESULTS: We identified at least 5,350 APPs in oncology and an additional 5,400 who might practice oncology. Survey respondents totaled 577 out of 3,055, which provided a 19% response rate. Results focused on 540 NPs and PAs. Greater than 90% reported satisfaction with career choice. Respondents identified predominately as white (89%) and female (94%). NPs and PAs spent the majority (80%) of time in direct patient care. The top four patient care activities were patient counseling (NPs, 94%; PAs, 98%), prescribing (NPs, 93%; PAs, 97%), treatment management (NPs, 89%; PAs, 93%), and follow-up visits (NPs, 81%; PAs, 86%). A majority of all APPs reported both independent and shared visits (65% hematology/oncology/survivorship/prevention/pediatric hematology/oncology; 85% surgical/gynecologic oncology; 78% radiation oncology). A minority of APPs reported that they conducted only shared visits. Average annual compensation was between $113,000 and $115,000, which is about $10,000 higher than average pay for APPs not in oncology. CONCLUSION: We identified 5,350 APPs in oncology and conclude that number may be as high as 7,000. Survey results suggest that practices that incorporate APPs routinely rely on them for patient care. Given the increasing number of patients with and survivors of cancer, APPs are important to ensure access to quality cancer care now and in the future.

Impaired hypothalamic-pituitary-testicular axis activity, spermatogenesis, and sperm function promote infertility in males with lead poisoning.

Lead poisoning is a stealthy threat to human physiological systems as chronic exposure can remain asymptomatic for long periods of time before symptoms manifest. We presently review the biophysical mechanisms of lead poisoning that contribute to male infertility. Environmental and occupational exposure of lead may adversely affect the hypothalamic-pituitary-testicular axis, impairing the induction of spermatogenesis. Dysfunction at the reproductive axis, namely testosterone suppression, is most susceptible and irreversible during pubertal development. Lead poisoning also appears to directly impair the process of spermatogenesis itself as well as sperm function. Spermatogenesis issues may manifest as low sperm count and stem from reproductive axis dysfunction or testicular degeneration. Generation of excessive reactive oxygen species due to lead-associated oxidative stress can potentially affect sperm viability, motility, DNA fragmentation, membrane lipid peroxidation, capacitation, hyperactivation, acrosome reaction, and chemotaxis for sperm-oocyte fusion, all of which can contribute to deter fertilization. Reproductive toxicity has been tested through cross-sectional analysis studies in humans as well as in vivo and in vitro studies in animals.

PAs in primary care: Current status and workforce implications.

OBJECTIVES: Understanding the PA primary care workforce is an initial step toward greater use of primary care PAs in new healthcare delivery models. This study sought to describe primary care PA practice as it compares with PA practice in other specialties. METHODS: Data from two 2015 national American Academy of Physician Assistants surveys were analyzed using descriptive statistics. Statistically significant differences between primary care and specialty PAs were assessed using tests of column proportions and tests of column means. RESULTS: Compared with PAs in specialties, primary care PAs were older, saw more patients per week, and spent less time consulting with physicians. In addition, higher percentages were Hispanic, had a record of military service, and had plans to leave their specialty or retire. CONCLUSIONS: Primary care PAs appear to possess unique strengths; however, challenges to maintaining a primary care PA workforce are substantial.

Ageing is associated with molecular signatures of inflammation and type 2 diabetes in rat pancreatic islets.

AIMS/HYPOTHESIS: Ageing is a major risk factor for development of metabolic diseases such as type 2 diabetes. Identification of the mechanisms underlying this association could help to elucidate the relationship between age-associated progressive loss of metabolic health and development of type 2 diabetes. We aimed to determine molecular signatures during ageing in the endocrine pancreas. METHODS: Global gene transcription was measured in pancreatic islets isolated from young and old rats by Ilumina BeadChip arrays. Promoter DNA methylation was measured by Sequenom MassArray in 46 genes that showed differential expression with age, and correlations with expression were established. Alterations in morphological and cellular processes with age were determined by immunohistochemical methods. RESULTS: Age-related changes in gene expression were found at 623 loci (>1.5-fold, false discovery rate [FDR] <5%), with a significant (FDR < 0.05) enrichment in genes previously implicated in islet-cell function (Enpp1, Abcc8), type 2 diabetes (Tspan8, Kcnq1), inflammatory processes (Cxcl9, Il33) and extracellular matrix organisation (Col3a1, Dpt). Age-associated transcriptional differences negatively correlated with promoter DNA methylation at several loci related to inflammation, glucose homeostasis, cell proliferation and cell-matrix interactions (Il33, Cxcl9, Gpr119, Fbp2, Col3a1, Dpt, Spp1). CONCLUSIONS/INTERPRETATION: Our findings suggest that a significant proportion of pancreatic islets develop a low-grade 'chronic' inflammatory status with ageing and this may trigger altered functional plasticity. Furthermore, we identified changes in expression of genes previously linked to type 2 diabetes and associated changes in DNA methylation that could explain their age-associated dysregulation. These findings provide new insights into key (epi)genetic signatures of the ageing process in islets.
