Surveying the Knowledge and Practices of Primary Care Residents in Managing Adult Patients with Obesity.

BACKGROUND: The prevalence of obesity is increasing worldwide at an alarming rate, yet obesity remains under-addressed during clinic encounters. A lack of training in how to treat obesity is one crucial factor contributing to this deficiency. OBJECTIVE: This study explored resident physicians' perceptions of their education on obesity and its relationship with confidence and practice behaviors when caring for patients with obesity. DESIGN: A survey was distributed to residency directors to share with residents in their programs. Participation was voluntary and anonymous. Data was collected over a 3-month period. PARTICIPANTS: Residents in Family Medicine and Internal Medicine programs in West Virginia and Indiana who saw adult patients in an ambulatory care setting. MAIN MEASURES: The electronic survey queried the presence of a formal curriculum on Obesity Medicine (OM) and each resident's knowledge, confidence, practice behaviors, and attitudes pertaining to OM. KEY RESULTS: The survey was distributed to 490 residents in 12 programs. Response rate was 22.9% (112 resident physicians). All respondents felt that medical training in obesity should be strengthened. Residents who reported having a formal curriculum on OM were more likely than those without a curriculum to rate their confidence as "high" when discussing weight (35.0% vs. 16.7%, p = 0.03) and when counseling patients about diet and nutrition (37.5% vs. 18.1%, p = 0.02). They also more frequently reported learning enough from faculty to manage obesity (65.0% vs. 29.2%, p < 0.001). Residents with an OM curriculum reported discussing obesity as a problem with patients (100.0% vs. 86.1%, p = 0.01), and completing motivational interviews (90.0% vs. 58.3%, p = < 0.001), more frequently than their peers without a curriculum. CONCLUSIONS: Residents with a formal OM curriculum were more confident in addressing and discussing obesity with patients. Formal training in OM will strengthen resident training to better address and treat patients with obesity.

Using the social cognitive theory to examine spontaneous attempts to quit illicit substance use.

Rural areas in the US exhibit high rates of illicit substance use. This study aimed to investigate the Social Cognitive Theory factors associated with spontaneous attempts to quit illicit substance use in a sample of users. A cross-sectional survey was administered through face-to-face interviews. Data was collected from adult (≥ 18 years of age) current illicit substance users who were not receiving professional addiction treatment. Binary logistic regression analyses were utilized to answer the research question. Data from 230 illicit substance users met the eligibility criteria. The mean age was 38 years, whereas the average history of illicit substance use was 14 years. Users with a higher perceived value of quitting illicit substance use were significantly more likely to attempt to quit use spontaneously. Health behavior interventions that incorporate the perceived value of quitting illicit substance use can be effective in encouraging spontaneous attempts to quit illicit substance use.

Emergence of Erythromycin-Resistant Invasive Group A Streptococcus, West Virginia, USA, 2020-2021.

Clindamycin and ß-lactam antibiotics have been mainstays for treating invasive group A Streptococcus (iGAS) infection, yet such regimens might be limited for strains displaying MLSB phenotypes. We investigated 76 iGAS isolates from 66 patients in West Virginia, USA, during 2020-2021. We performed emm typing using Centers for Disease Control and Prevention guidelines and assessed resistance both genotypically and phenotypically. Median patient age was 42 (range 23-86) years. We found 76% of isolates were simultaneously resistant to erythromycin and clindamycin, including all emm92 and emm11 isolates. Macrolide resistance was conferred by the plasmid-borne ermT gene in all emm92 isolates and by chromosomally encoded ermA, ermB, and a single mefA in other emm types. Macrolide-resistant iGAS isolates were typically resistant to tetracycline and aminoglycosides. Vulnerability to infection was associated with socioeconomic status. Our results show a predominance of macrolide-resistant isolates and a shift in emm type distribution compared with historical reports.

'The High Five Club': Social Relations and Perspectives on HIV-Related Stigma During an HIV Outbreak in West Virginia.

In the United States, HIV outbreaks are occurring in areas most affected by the opioid epidemic, including West Virginia (WV). Cultural Theory contends that multiple cultures co-exist within societies distinguished by their differing intensities of rules or norms of behavior ('grid') or degree of group allegiance/individual autonomy ('group'). Accordingly, we would expect that perceptions about HIV, including stigma, correspond with individuals' grid/group attributes. To explore this, we conducted qualitative interviews with people who inject drugs (PWID) recruited from a WV syringe service program. This paper focuses on our unexpected findings on stigma during a coinciding HIV outbreak. PWID living homeless identified as belonging to a 'street family'. Its members were mutually distrustful and constrained by poverty and drug dependence but despite their conflicts, reported openness between each other about HIV + status. Interviewees living with HIV perceived little enacted stigma from peers since the local outbreak. Contrasting stigmatizing attitudes were attributed to the town's mainstream society. The 'High Five' (Hi-V) Club, expressing defiance towards stigmatizing behavior outside the street family, epitomized the tensions between a desire for solidary and mutual support and a fatalistic tendency towards division and distrust. Fatalism may hinder cooperation, solidarity and HIV prevention but may explain perceived reductions in stigma.

Evaluating Mechanisms of Short-term Woodland Salamander Response to Forest Management.

Contemporary forest management often requires meeting diverse ecological objectives including maintaining ecosystem function and promoting biodiversity through timber harvesting. Wildlife are essential in this process by providing ecological services that can facilitate forest resiliency in response to timber harvesting. However, the mechanisms driving species' responses remain ambiguous. The goal of this study was to assess mechanisms influencing eastern red-backed salamander (RBS; Plethodon cinereus) response to overstory cover removal. We evaluated two mitigation strategies for the RBS in response to overstory removal. We used a before-after-control-impact design to study how (1) retaining residual trees or (2) eliminating soil compaction affected RBS surface counts and body condition index (BCI) up to two-years post-treatment. Additionally, we assessed how surface counts of RBS were influenced by overstory tree cover. Surface counts of RBS were not strongly influenced by overstory removal when tree residuals were retained. Body condition index increased in treatments where harvest residuals were retained. In treatments where soil compaction was eliminated, surface counts and BCI were inversely related. Finally, surface counts from both mitigation strategies were not strongly influenced by overstory cover. Overall, both mitigation techniques appeared to ameliorate impacts of overstory removal on RBS. These results highlight the importance of understanding mechanisms driving species' responses to forest management. To reduce the perceived negative effects of overstory removal on RBS, incorporating these mitigation measures may contribute to the viability and stability of RBS populations. Incorporating species' life history traits into management strategies could increase continuity of ecological function and integrity through harvesting.

Evaluation of self-measured blood pressure monitoring in a southern rural West Virginia health system.

INTRODUCTION: At the time of the 2021 Behavioral Risk Factor Surveillance System survey, an estimated 32.3% of adults in the US and nearly half (43.4%, 776 000) of adults in West Virginia (WV) had hypertension. Further, the Interactive Atlas of Heart Disease and Stroke estimates an increase in the percentage of adults with hypertension in the US from 32.3% to 47.0%, with hypertension rates in WV rising as high as 58.7%, indicating a significant public health concern in the community. Hypertension increases the risk of several negative health outcomes, including heart disease and stroke, and leads to increased economic and chronic disease burden. Although certain unmodifiable factors (sex, age, race, ethnicity, and family history) increase the risk of developing hypertension, a healthy lifestyle - including a nutritious diet, maintaining a healthy weight, avoiding nicotine products, and participating in regular moderate physical activity - can decrease the risk of developing hypertension. Self-measured blood pressure (SMBP) monitoring, or home BP monitoring, when integrated with a provider's clinical management approach, is linked to improvements in BP management and control. This study represents a mid-point assessment of a remote SMBP monitoring program implemented by Cabin Creek Health Systems (CCHS), a federally qualified health center, and its impact on BP control. METHODS: CCHS implemented SMBP programming in March 2020 as one element of a developing comprehensive program aimed at reducing uncontrolled hypertension, and therefore chronic disease burden, in its service area and patient population. The project, funded by the Health Resources and Services Administration, continued to February 2023. This report represents a mid-point analysis and was based on the retrospective analysis of de-identified data collected for 234 patients to June 2022, who were assessed for changes in BP between the date of enrollment and the most recently available BP measurement. Patients were enrolled in the SMBP program if they exhibited current or previous indicators of uncontrolled hypertension (systolic ≥140 mmHg and/or diastolic ≥90 mmHg), at the discretion of their provider, and were equipped with an iBloodPressure cellular connected home BP monitoring system, manufactured by Smart Meter. Their BP readings were documented in the integration software TimeDoc Health and electronic health record athenahealth. RESULTS: At the time of enrollment, 201 (86.0%) patients had uncontrolled hypertension, with 116 (49.6%) patients having both uncontrolled systolic (≥140 mmHg) and diastolic (≥90 mmHg) values. At follow-up, the number of patients with uncontrolled hypertension decreased from 201 to 98 (41.9%), with only 36 (15.4%) patients having both uncontrolled systolic and diastolic values. Additionally, 26 (11.1%) patients were in hypertensive crisis at the time of enrollment, and no patients remained in crisis at the time of follow-up. The number of patients with BP values in the controlled range (systolic <140 mmHg and diastolic <90 mmHg) increased from 33 (14.1%) at enrollment to 136 (58.1%) at follow-up. Overall, there was a 44.0% increase in the number of patients with BP values in the controlled range at follow-up, and a concomitant 44.1% decrease in the number of patients in the uncontrolled range. These observations were consistent across multiple demographic indicators, including clinic location, three-digit zip code, and patient sex. CONCLUSION: Systematic implementation of remote BP monitoring, when integrated into clinician workflows, was associated with a substantial reduction in the number of patients with uncontrolled hypertension in this rural federally qualified health center. Further, CCHS was successful in implementing a remote SMBP monitoring program in a community challenged with transportation insecurity, and poor cellular and broadband access, of which lessons learned are applicable to other health systems interested in pursuing comparable efforts.

Caffeine consumption and onset of alcohol use among early adolescents.

Preventing or delaying the onset of alcohol use among children and youth is an important public health goal. One possible factor in alcohol use onset among early adolescents is caffeine. The aim of this study was to assess the possible contribution of caffeine to the onset of alcohol use during early adolescence. We used data from the Young Mountaineer Health Study Cohort. Survey data were collected from 1349 (response rate: 80.7%) 6th grade students (mean age at baseline 11.5 years) in 20 middle schools in West Virginia during the fall of 2020, and again approximately 6 months later in spring of 2021. We limited our analyses to students reporting never having used any form of alcohol at baseline. Logistic regression was employed in multivariable analyses and both Odds Ratios and Relative Risks reported. At follow-up, almost 14% of participants reported having consumed alcohol at least once and 57% used caffeine of 100 mg + daily. In multivariable analyses we controlled for social and behavioral variables known to impact tobacco use. Caffeine use was operationalized as a three-level factor: no use, <100 mg per day, and 100 + mg per day, with the latter being the approximate equivalent of the minimum of a typical cup of coffee or can of energy drink. Caffeine use of 100 mg + per day was significantly related to alcohol use at 6-months follow-up (OR: 1.79, RR: 1.56, p = .037). We conclude that caffeine consumption among 11-12-year-old adolescents may be a factor in early onset of alcohol use.

Opioid Litigation: Lessons Learned from a Retail Pharmacy Settlement.

As the opioid epidemic continues in the United States and ongoing litigation seeks to hold contributors responsible, state governments have initiated lawsuits against retail pharmacies for their role in contributing to the crisis. This article summarizes an action the State of West Virginia brought against CVS, which the parties recently settled in the fall of 2022. This article examines the unique position of retail pharmacies like CVS, which often serve as both distributors and dispensers, in contributing to the oversaturation and illicit diversion of opioid prescriptions. The article concludes by assessing the viability of potential causes of action against retail pharmacies in opioid litigation.

Disparities in neonatal abstinence syndrome and health insurance status: A statewide study using non-claims real-time surveillance data.

BACKGROUND: Most studies examining the relationship between neonatal abstinence syndrome (NAS) and health insurance status in the United States (USA) have used administrative insurance claims data, which is subject to myriad limitations. We examined the association between NAS and health insurance status in a large geographically defined rural population in the United States, using non-claims data. METHODS: We utilized data from a population-based cohort of all newborns born in 2017-2019 in the rural state of West Virginia (WV) and restricted analyses to WV residents' births (n = 46 213). NAS was defined as neonatal withdrawal from many substances, including opiates and not limited to those cases that require pharmacological treatment. RESULTS: Medicaid covered more than half (52.6%) of all infants' births in the state of WV. The incidence of NAS was 85.8 and 12.7 per 1000 livebirths in the Medicaid and privately insured groups, respectively. Among all infants diagnosed with NAS, 86.1% were enrolled in the state's Medicaid programme. The risk of NAS in the Medicaid-insured newborns was higher than privately insured newborns in the unadjusted analysis (risk ratio (RR) 6.76, 95% confidence interval (CI) 5.95, 7.68) and the adjusted analysis RR 3.00, 95% CI 2.01, 4.49); adjusted risk difference 20.3 (95% CI 17.5, 23.1 cases per 1000 livebirths). CONCLUSIONS: NAS is an important indicator of the immediate effect of the opioid crisis. This study shows the disparity in NAS by health insurance status for a large rural population in the United States, and its burden on the state's Medicaid programme. Providing timely and accurate estimates of NAS is important for public health policies and decision making.

Campus Service Use Among Students With Disabilities Who Have Experienced Sexual Violence: A Conceptual Model.

Students with disabilities are one student group with elevated risk of sexual violence. Although they would benefit from streamlined access to campus support, little is known about their patterns of campus service use. This qualitative analysis includes data from semi-structured interviews with 51 students with disabilities who experienced sexual violence focused on service use across campus. The resultant conceptual model shows that greater accessibility is associated with positive experiences, and lower accessibility is associated with negative experiences. Students with disabilities who experienced or expected negative reactions (e.g., judgment) were less likely to use services and were less satisfied. Advocacy and support in connecting students with disability or sexual violence services was associated with positive experiences and increased accessibility. These findings highlight key facilitators and barriers to campus service use for students with disabilities with sexual violence histories and suggest key intervention points for increasing accessibility, reducing stigma, and improving student experiences with campus providers, staff, and faculty.

Cost and Effectiveness of Reminders to Promote Colorectal Cancer Screening Uptake in Rural Federally Qualified Health Centers in West Virginia.

The purpose of this study is to evaluate the effectiveness of the West Virginia Program to Increase Colorectal Cancer Screening in implementing patient reminders to increase fecal immunochemical test (FIT) kit return rates in nine federally qualified health centers (FQHCs). Using process measures and cost data collected, the authors examined the differences in the intensity of the phone calls across FQHCs and compared them with the return rates achieved. They also reported the cost per kit successfully returned as a result of the intervention. Across all FQHCs, 5,041 FIT kits were ordered, and the initial return rate (without a reminder) was 41.1%. A total of 2,201 patients received reminder phone calls; on average, patients received 1.61 reminder calls each. The reminder interventions increased the average FIT kit return rate to 60.7%. The average total cost per FIT kit returned across all FQHCs was $60.18, and the average cost of only the reminders was $11.20 per FIT kit returned. FQHCs achieved an average increase of 19.6 percentage points in FIT kit return rates, and costs across clinics varied. Clinics with high-quality health information systems that enabled tracking of patients with minimal effort were able to implement lower cost reminder interventions.

Existence of a Strong Correlation of Biomarkers and miRNA in Females with Metabolic Syndrome and Obesity in a Population of West Virginia.

Objectives: Metabolic syndrome causes complications like cardiovascular disease and type 2 diabetes mellitus (T2DM). As metabolic syndrome develops, altered levels of cytokines and microRNAs (miRNA) are measurable in the circulation. We aimed to construct a panel detecting abnormal levels of cytokines and miRNAs in patients at risk for metabolic syndrome. Methods: Participants included 54 patients from a Family Medicine Clinic at Marshall University School of Medicine, in groups of: Control, Obese, and Metabolic Syndrome (MetS). Results: Serum levels of leptin, adiponectin, leptin: adiponectin ratio, IL-6, six miRNAs (320a, 197-3p, 23-3p, 221-3p, 27a-3p, and 130a-3p), were measured. Among the three groups, leptin, and leptin: adiponectin ratio, and IL-6 levels were highest in MetS, and levels in Obese were greater than Control (p>0.05). Adiponectin levels were lower in Obese compared to Control, but lowest in MetS (p<0.05). MiRNAs levels were lowest in MetS, and levels in Obese were lower than Control (p>0.05). Conclusion: Our results support the clinical application of biomarkers in diagnosing early stage MetS, which will enable attenuation of disease progression before onset of irreversible complications. Since West Virginians are high-risk for developing MetS, our biomarker panel could reduce the disease burden on our population.

A Structural Equation Modeling approach to water quality perceptions.

Researches on water quality perceptions have used various techniques and models to explain relationships between specific variables. Surprisingly, Structural Equation Modeling (SEM) has received little attention in water quality perceptions studies, and reporting has been inconsistent among existing studies. One objective of this article is to provide readers with a methodological example for conducting and reporting SEM. Another objective is to build a model that explains the different relationships among the diverse factors highlighted by previous studies on water quality perceptions. Our study focuses on the factors influencing people's perceptions of water quality in the Appalachian region. As such, researchers have conducted a survey in a mid-sized city in northcentral West Virginia to assess residents' perceptions of water quality for drinking and recreational purposes. Specifically, we aimed to understand the relationships between perceived water quality, health risk perceptions, organoleptic perceptions, environmental concern, area satisfaction and perceptions of surface water quality. Our model provided a good fit that explained about 50% of the variance in health risk perceptions and 43% of the variance in organoleptic perceptions. Environmental concern, area satisfaction and perceived surface water quality are important factors in explaining these variances. Perceived water quality was dismissed in our analysis due to multicollinearity. Our study demonstrates that risk communication needs to be better addressed by local decision-makers and water managers.

Crude 4-methylcyclohexanemethanol (MCHM) did not cause skin irritation in humans in 48-h patch test.

Crude 4-methylcyclohexanemethanol (MCHM) is an industrial chemical used to wash and clean coal. On January 9th, 2014 approximately 10,000 gallons of a mixture containing crude MCHM were released into the Elk River near Charleston, West Virginia, contaminating the local water supply. Following the spill, residents reported numerous health complaints, and sought medical attention for ailments including rashes and itching. The relationship between the complaints and the spill were unknown, as such symptoms are reported frequently in the background. In this study, the primary irritation potential of crude MCHM was evaluated in 206 individuals who underwent 48 hour semi-occluded patch testing. MCHM concentrations assessed in this study were 1, 5, 15, and 100 ppm. No appreciable skin reactions were observed in individuals at any concentration. Three of the five concentrations evaluated were above the highest measured concentration of MCHM in the tap water of residents in West Virginia (3.7 ppm). The results of this study suggest that crude MCHM would not be a dermal irritant for the vast majority, if not all, potentially exposed persons at the concentrations in the water reported after the spill.

Role of Serum Biomarkers in Early Detection of Diabetic Cardiomyopathy in the West Virginian Population.

OBJECTIVES: Diabetic cardiomyopathy (DCM) is an established complication of diabetes mellitus. In West Virginia, the especially high incidence of diabetes and heart failure validate the necessity of developing new strategies for earlier detection of DCM. Since most DCM patients remain asymptomatic until the later stages of the disease when the fibrotic complications become irreversible, we aimed to explore biomarkers that can identify early-stage DCM. METHODS: The patients were grouped into 4 categories based on clinical diabetic and cardiac parameters: Control, Diabetes (DM), Diastolic dysfunction (DD), and Diabetes with diastolic dysfunction (DM+DD), the last group being the preclinical DCM group. RESULTS: Echocardiography images indicated severe diastolic dysfunction in patients with DD+DM and DD compared to DM or control patients. In the DM and DM+DD groups, TNFα, isoprostane, and leptin were elevated compared to control (p<0.05), as were clinical markers HDL, glucose and hemoglobin A1C. Fibrotic markers IGFBP7 and TGF-ß followed the same trend. The Control group showed higher beneficial levels of adiponectin and bilirubin, which were reduced in the DM and DM+DD groups (p<0.05). CONCLUSION: The results from our study support the clinical application of biomarkers in diagnosing early stage DCM, which will enable attenuation of disease progression prior to the onset of irreversible complications.

West Virginia Mosquitoes: Sequential List by Publication, Newly Found Species, Corrections, and Notes for Earlier Records.

A chronological list of species based on date of publication is provided for confirmed mosquito species in West Virginia. Five additional newly found species in the state are documented with collection data. Two previously misidentified or mislabeled published records are corrected. The number of confirmed species occurring in the state is now 35, and many more species are likely present, but undetected. Significant populations of 4 widely distributed known vector species, Aedes albopictus , Ae. japonicus japonicus, Ae. triseriatus, and Culex pipiens , in West Virginia signal an urgent need for additional studies, surveillance, and increased mosquito control efforts to help prevent future native and invasive arbovirus infections and outbreaks in local residents.

La Crosse Virus in Aedes japonicus japonicus mosquitoes in the Appalachian Region, United States.

La Crosse virus (LACV), a leading cause of arboviral encephalitis in children in the United States, is emerging in Appalachia. For local arboviral surveillance, mosquitoes were tested. LACV RNA was detected and isolated from Aedes japonicus mosquitoes. These invasive mosquitoes may significantly affect LACV range expansion and dynamics.

Are residents of mountain-top mining counties more likely to have infants with birth defects? The West Virginia experience.

BACKGROUND: Pooled 1996 to 2003 birth certificate data for four central states in Appalachia indicated higher rates of infants with birth defects born to residents of counties with mountain-top mining (MTM) than born to residents of non-mining-counties (Ahern 2011). However, those analyses did not consider sources of uncertainty such as unbalanced distributions or quality of data. Quality issues have been a continuing problem with birth certificate analyses. We used 1990 to 2009 live birth certificate data for West Virginia to reassess this hypothesis. METHODS: Forty-four hospitals contributed 98% of the MTM-county births and 95% of the non-mining-county births, of which six had more than 1000 births from both MTM and nonmining counties. Adjusted and stratified prevalence rate ratios (PRRs) were computed both by using Poisson regression and Mantel-Haenszel analysis. RESULTS: Unbalanced distribution of hospital births was observed by mining groups. The prevalence rate of infants with reported birth defects, higher in MTM-counties (0.021) than in non-mining-counties (0.015), yielded a significant crude PRR (cPRR = 1.43; 95% confidence interval [CI] = 1.36-1.52) but a nonsignificant hospital-adjusted PRR (adjPRR = 1.08; 95% CI = 0.97-1.20; p = 0.16) for the 44 hospitals. So did the six hospital data analysis ([cPRR = 2.39; 95% CI = 2.15-2.65] and [adjPRR = 1.01; 95% CI, 0.89-1.14; p = 0.87]). CONCLUSION: No increased risk of birth defects was observed for births from MTM-counties after adjustment for, or stratification by, hospital of birth. These results have consistently demonstrated that the reported association between birth defect rates and MTM coal mining was a consequence of data heterogeneity. The data do not demonstrate evidence of a "Mountain-top Mining" effect on the prevalence of infants with reported birth defects in WV.

"Fighting demons": Stigma and shifting norms in explicit mention of overdose in obituaries, 2010-2019.

Obituaries are often the only published record of an individual's life and elicit community reactions, including stigmatization. Because obituaries are typically written by the bereaved, their content reflects the writer's perceptions of mores governing the social context of the next-of-kin and decedent. When a cause of death is stigmatized, it can influence the way the bereaved write the obituary. However, what constitutes a stigmatized cause of death may change as larger societal discourses of morality shift and conditions or events become framed differently. Using a sample of obituaries (N = 210) from obituary aggregator Legacy.com of "off-time," or premature, deaths in West Virginia from 2010, 2015, 2017, and 2019, this article explores whether the presentation of overdose deaths in obituaries changes alongside the shift in the public framing of the opioid crisis as medical rather than criminal. I find obituaries including terms associated with drug use and overdose become both more common and explicit over the course of the study period. This suggests that the shift in public framing of the opioid crisis from criminalization to medicalization corresponds with a decrease in drug stigmatization in obituaries. Obituary analysis can be a useful means of exploring the stigmatization of other controversial causes of death, such as suicide, cirrhosis, and lung cancer.

Nomenclatural history of Megalonyx Jefferson, 1799 (Mammalia, Xenarthra, Pilosa, Megalonychidae).

Both authorship and spelling of the extinct giant sloth genus Megalonyx and its type species, M.jeffersonii (Mammalia, Xenarthra, Pilosa, Megalonychidae), have been inconsistent. The genus-group name has been cited with two different authorships and three dates, and it has been spelled with two different suffixes. The species-group name has been cited with four different authors and dates, and it has been spelled with two different endings. Megalonyx Jefferson, 1799 is the first valid use of the genus-group name; the correct original spelling has the -onyx suffix. The type species of Megalonyx is Megatheriumjeffersonii Desmarest, 1822; the correct original spelling has an -ii ending. A vernacular word, megalonyx, refers to species classified in the genus Megalonyx Jefferson, 1799.
