Trends in coverage and reimbursement for reproductive genetic counseling in New Jersey by multiple payers from 2010 to 2018

J Genet Couns. 2021 Jul 5. doi: 10.1002/jgc4.1443. Online ahead of print.

ABSTRACT

Lack of consistent insurance coverage for genetic counseling services billed under Current Procedural Terminology (CPT) code 96040 creates a barrier for access to this service. This retrospective study examined coverage and reimbursement for reproductive genetic counseling encounters billed under CPT code 96040 as a professional fee over an eight-year period at Rutgers Robert Wood Johnson Medical School, a regional perinatal center in New Jersey, a state requiring licensure. Descriptive statistics were tabulated to assess the disparity between Medicare/Medicaid, Managed Care Medicaid, and commercial insurance payers, including how often encounters were covered and if reimbursed, at what percentage of the amount billed. A comparison of individual plan types (Health Maintenance Organization, Point of Service, and Preferred Provider Organization) was carried out. Overall trends in reimbursement were assessed across payers. The study found 61% of 60-min encounters billed to Medicare/Medicaid, Managed Care Medicaid, and commercial insurance payers received coverage. Of all covered 60-min encounters billed to Managed Care Medicaid and commercial insurance payers, an average of 36% of the amount billed was reimbursed. Medicare/Medicaid encounters were never reimbursed. Commercial insurance covered 65% of encounters billed but this varied between payers. Across all payers, an overall downward trend of reimbursement was demonstrated over the eight-year period. Lack of consistent service coverage creates a barrier and patients cannot universally access genetic counseling services. Steps to improve coverage need to include passing of legislation, notably the next bill to replace the former H.R. 3235, ‘Access to Genetic Counselor Services Act of 2019’ and provisions within third-party payers that allow for credentialing of genetic counseling providers.

Daytime and nocturnal activity in treated dogs with idiopathic epilepsy compared to matched unaffected controls

J Vet Intern Med. 2021 Jul 5. doi: 10.1111/jvim.16205. Online ahead of print.

ABSTRACT

BACKGROUND: In dogs, antiepileptic drugs (AED) cause lethargy but quantitative data regarding the effects of AED on activity levels are not available, and little is known about how AEDs affect sleep quality.

OBJECTIVE: To quantitatively compare activity levels and nocturnal activity in dogs previously diagnosed with idiopathic epilepsy (IE) receiving AEDs compared to age- and breed-matched control dogs.

ANIMALS: Sixty-two dogs with IE and 310 control dogs.

METHODS: This is a 3-month prospective parallel observational study. An activity monitoring device for dogs was used to measure daily activity levels and sleep scores in all dogs.

RESULTS: Dogs with IE treated with AEDs had an 18% average lower baseline activity level compared to control dogs (P = .005; point estimate = 0.82, 95% confidence interval [CI], 0.75-0.90). The combination of phenobarbital and potassium bromide (KBr) was associated with an average 28% decrease in activity in dogs with IE compared to control dogs (P = .03; point estimate = 0.72; CI, 0.62-0.82). Mean sleep scores were not significantly different in dogs with IE receiving AEDs compared to control dogs (P = .43). However, higher dosages of KBr were associated with lower sleep scores (P = .01).

CONCLUSIONS: Dogs with IE receiving AEDs have lower activity levels, but no difference in sleep scores, compared to controls. The combination of phenobarbital and KBr had the largest decrease in activity between groups. Higher doses of KBr may affect nocturnal activity in epileptic dogs.

Effective Lockdown and Role of Hospital-Based COVID-19 Transmission in Some Indian States: An Outbreak Risk Analysis

Risk Anal. 2021 Jul 5. doi: 10.1111/risa.13781. Online ahead of print.

ABSTRACT

Several reports in India indicate hospitals and quarantined centers are COVID-19 hotspots. To study the transmission occurring from the hospitals and as well as from the community, we developed a mechanistic model with a lockdown effect. Using daily COVID-19 cases data from six states and overall India, we estimated several important parameters of our model. Moreover, we provided an estimation of the effective (RT ), the basic (R0 ), the community (RC ), and the hospital (RH ) reproduction numbers. We forecast COVID-19 notified cases from May 3, 2020, till May 20, 2020, under five different lockdown scenarios in the seven locations. Our analysis suggests that 65% to 99% of the new COVID-19 cases are currently asymptomatic in those locations. Besides, about 1-16% of the total COVID-19 transmission are currently occurring from hospital-based contact and these percentage can increase up to 69% in some locations. Furthermore, the hospital-based transmission rate (β2 ) has significant positive (0.65 to 0.8) and negative (-0.58 to -0.23) correlation with R0 and the effectiveness of lockdown, respectively. Therefore, a much larger COVID-19 outbreak may trigger from the hospital-based transmission. In most of the locations, model forecast from May 3, 2020, till May 20, 2020, indicates a two-times increase in cumulative cases in comparison to total observed cases up to April 29, 2020. Based on our results, we proposed a containment policy that may reduce the threat of a larger COVID-19 outbreak in the future.

A Randomized Controlled Trial of Early versus Late Surgical Decompression for Thoracic and Thoracolumbar Spinal Cord Injury in 73 Patients

Neurotrauma Rep. 2020 Sep 18;1(1):78-87. doi: 10.1089/neur.2020.0027. eCollection 2020.

ABSTRACT

Convincing clinical evidence exists to support early surgical decompression in the setting of cervical spinal cord injury (SCI). However, clinical evidence on the effect of early surgery in patients with thoracic and thoracolumbar (from T1 to L1 [T1-L1]) SCI is lacking and a critical knowledge gap remains. This randomized controlled trial (RCT) sought to evaluate the safety and efficacy of early (<24 h) compared with late (24-72 h) decompressive surgery after T1-L1 SCI. From 2010 to 2018, patients (≥16 years of age) with acute T1-L1 SCI presenting to a single trauma center were randomized to receive either early (<24 h) or late (24-72 h) surgical decompression. The primary outcome was an ordinal change in American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade at 12-month follow-up. Secondary outcomes included complications and change in ASIA motor score (AMS) at 12 months. Outcome assessors were blinded to treatment assignment. Of 73 individuals whose treatment followed the study protocol, 37 received early surgery and 36 underwent late surgery. The mean age was 29.74 ± 11.4 years. In the early group 45.9% of patients and in the late group 33.3% of patients had a ≥1-grade improvement in AIS (odds ratio [OR] 1.70, 95% confidence interval [CI]: 0.66-4.39, p = 0.271); significantly more patients in the early (24.3%) than late (5.6%) surgery group had a ≥2-grade improvement in AIS (OR 5.46, 95% CI: 1.09-27.38, p = 0.025). There was no statistically significant difference in the secondary outcome measures. Surgical decompression within 24 h of acute traumatic T1-L1 SCI is safe and is associated with improved neurological outcome, defined as at least a 2-grade improvement in AIS at 12 months.

An efficient and robust procedure to calculate absorption spectra of aqueous charged species applied to NO2

Phys Chem Chem Phys. 2021 Jul 5. doi: 10.1039/d1cp00652e. Online ahead of print.

ABSTRACT

Accurate calculation of absorption spectra of aqueous NO2- requires rigorously sampling the quantum potential energy surfaces for microsolvation of NO2- with at least five explicit water molecules and embedding the resulting clusters in a continuum solvent accounting for the statistical weighted contributions of individual isomers. This method, which we address as ASCEC + PCM, introduces several desired features when compared against MD simulations derived QM/MM spectra: comparatively fewer explicit solvent molecules to be treated with expensive QM methods, the identification of equilibrium structures in the quantum PES to be used in further vibrational spectroscopy, and the unequivocal identification of cluster orbitals undergoing electronic transitions and charge transfer that originate the spectral bands.

Serious Illness Conversation-Evaluation Exercise: A Novel Assessment Tool for Residents Leading Serious Illness Conversations

Palliat Med Rep. 2020 Nov 24;1(1):280-290. doi: 10.1089/pmr.2020.0086. eCollection 2020.

ABSTRACT

Background/Objectives: The serious illness conversation (SIC) is an evidence-based framework for conversations with patients about a serious illness diagnosis. The objective of our study was to develop and validate a novel tool, the SIC-evaluation exercise (SIC-Ex), to facilitate assessment of resident-led conversations with oncology patients. Design: We developed the SIC-Ex based on SIC and on the Royal College of Canada Medical Oncology milestones. Seven resident trainees and 10 evaluators were recruited. Each trainee conducted an SIC with a patient, which was videotaped. The evaluators watched the videos and evaluated each trainee by using the novel SIC-Ex and the reference Calgary-Cambridge guide (CCG) at months zero and three. We used Kane’s validity framework to assess validity. Results: Intra-class correlation using average SIC-Ex scores showed a moderate level of inter-evaluator agreement (range 0.523-0.822). Most evaluators rated a particular resident similar to the group average, except for one to two evaluator outliers in each domain. Test-retest reliability showed a moderate level of consistency among SIC-Ex scores at months zero and three. Global rating at zero and three months showed fair to good/very good inter-evaluator correlation. Pearson correlation coefficients comparing total SIC-Ex and CCG scores were high for most evaluators. Self-scores by trainees did not correlate well with scores by evaluators. Conclusions: SIC-Ex is the first assessment tool that provides evidence for incorporating the SIG guide framework for evaluation of resident competence. SIC-Ex is conceptually related to, but more specific than, CCG in evaluating serious illness conversation skills.

Epilepsy and syphilis: A systematic review and meta-analysis

Indian J Dermatol Venereol Leprol. 2021 [SEASON];87(4):483-490. doi: 10.25259/IJDVL_681_19.

ABSTRACT

BACKGROUND: Epileptic seizures were noted as one of the most overlooked manifestations in syphilis; therefore a few clinicians are concerned about the relationship between epilepsy and syphilis. Our study sought to clarify the prevalence and clinical features of epileptic seizures in patients with syphilis.

METHODS: We retrieved relevant articles from different databases, using the keywords “syphilis and epilepsy” and then performed statistical analysis to characterize the relationship between these diseases.

RESULTS: Forty one articles were included in this study: eight described the prevalence of syphilis and epilepsy and the remaining 33 were case reports on syphilis with epileptic seizures. The meta-analysis included 1252 patients with syphilis. The pooled estimate of proportion of prevalence (95% confidence interval) was 0.1384 (0.0955-0.2005), and the proportion and heterogeneity showed different degrees of change among three subgroups. The systematic review included 46 cases of syphilis with epileptic seizures. Thirty two (80%) patients had motor seizures, among whom 20 (62.5%) had tonic-clonic seizures. In addition, 30 (75%) patients had impaired awareness and 18 (45%) had status seizures. Twenty five (62.5%) patients were 35-55 years of age, and 77.5% of the included patients were men. Thirty seven (97.4%) patients were seizure-free after anti-syphilis treatment.

LIMITATIONS: Research in this field has been conducted for a relatively short period and publication bias may exist. Furthermore, some patients with syphilis and epileptic seizures may not have received a clear diagnosis.

CONCLUSION: The proportion of prevalence was 0.1384. Most of the included patients were 35-55 years of age and had impaired awareness and motor seizures. Many patients with syphilis and epileptic seizure showed full recovery or the development of minor neurological sequelae, and nearly all patients were seizure-free after timely anti-syphilis treatment.

Development of a novel loop-mediated isothermal amplification assay for rapid detection of Mycobacterium leprae in clinical samples

Indian J Dermatol Venereol Leprol. 2021 [SEASON];87(4):491-497. doi: 10.25259/IJDVL_248_19.

ABSTRACT

BACKGROUND: Sensitive and definitive diagnostic tests are required for timely treatment of leprosy and to control its transmission.

AIM: In the present study, we report the development of loop-mediated isothermal amplification assay using six primers targeting the RLEP gene sequence uniquely present in Mycobacterium leprae.

METHODS: Tissue punch samples (n = 50) and slit aspirates (n = 50) from confirmed cases of leprosy (M. leprae positive by quantitative polymerase chain reaction), reporting at the Department of Dermatology, Safdarjung Hospital, New Delhi, were analyzed using newly developed closed tube loop-mediated isothermal amplification assay. The sensitivity and specificity; positive predictive value, negative predictive value and accuracy were calculated using MedCalc statistical software.

RESULTS: The loop-mediated isothermal amplification assay specifically amplified M. leprae genomic DNA with an analytical sensitivity of 100 fg. About 47 Out of the 50 quantitative polymerase chain reactions confirmed M. leprae positive tissue samples, 47 were positive by loop-mediated isothermal amplification assay (sensitivity 94%; 95% confidence interval 83.5%-98.8%) while only 31/50 were positive by histopathology (sensitivity 62%; 95% confidence interval 47.2%-75.4%) . Using slit aspirate samples of these 50 patients, 42 were positive by both quantitative polymerase chain reaction and loop-mediated isothermal amplification assay (sensitivity 84%; 95% confidence interval 70.9%-92.8%) while only 23/50 (sensitivity 46%; 95% confidence interval 31.8%-60.7%) were positive by microscopy.

LIMITATIONS: In the present study, the leprosy patient cohort was not uniform, as it comprised a lower number of paucibacillary cases (22%) compared to multibacillary (78%) cases.

CONCLUSION: Loop-mediated isothermal amplification assay established here provides a rapid and accurate diagnostic test for leprosy in terms of sensitivity and specificity. The assay is simple to perform in comparison with other molecular techniques (polymerase chain reaction/quantitative polymerase chain reaction) and has potential for field applicability.

Evaluation of internal and external hexagon connections in immediately loaded full-arch rehabilitations: A within-person randomized split-mouth controlled trial with a 3-year follow-up

Clin Implant Dent Relat Res. 2021 Jul 4. doi: 10.1111/cid.13029. Online ahead of print.

ABSTRACT

BACKGROUND: Although full-arch immediately loaded rehabilitations are widely used nowadays, little information is available on which implant/abutment connection is the most suitable in this type of treatment.

PURPOSE: The aim of the present multicentric split-mouth clinical trial was to compare the clinical outcomes of two different implant-abutment connections applied in full-arch immediate loading rehabilitations: external hexagon connection (EHC) versus internal hexagon connection (IHC).

MATERIALS AND METHODS: Twenty patients were rehabilitated with immediately loaded fixed full-arch rehabilitations. All the implants presented the same macro- and micro-topography but different implant/abutment connection. IHC were used in one randomly selected side of the jaw and EHC in the other side. Outcome measures were implant survival rate, peri-implant marginal bone loss (MBL), plaque index (PI), probing depth (PD), and bleeding on probing (BoP) evaluated at 3, 6, 12, and 36-month post-loading. Any technical and biological complication was recorded. Kaplan-Meier procedure and linear mixed model were used to perform statistical analysis.

RESULTS: Forty-three EHC and 40 IHC implants were inserted. No patients dropped out and two implants failed in the first 6 months. The CSR was 97.7% for EHC and 97.5% for IHC implants. No statistically significant differences were found among the two groups for any of the parameters at any time point. At the 36-month follow-up visit a slight difference was found in MBL with a mean value of 1.7 mm in the EHC and of 1.9 mm in the IHC group (p = 0.355). No biologic complications were identified. Seven loosed abutment screws were identified in the entire follow-up period, two in the EHC, and five in the IHC group without a statistically significant difference (p = 0.394).

CONCLUSIONS: After 36 months in function, both internal and external hexagon connections provided good clinical outcomes and were not associated with any significant difference.

PPAR-γ-induced Changes in Visceral Fat and Adiponectin Levels are Associated with Improvement of Steatohepatitis in Patients with NASH

Liver Int. 2021 Jul 5. doi: 10.1111/liv.15005. Online ahead of print.

ABSTRACT

BACKGROUND&AIMS: PPAR-γ agonists decrease hepatic/visceral fat (VF) and improve necroinflammation despite subcutaneous (SC) fat weight-gain. Understanding the impact of changes in VF, VF-to-SC distribution (VF/SC) and adiponectin levels in relation to histological improvement after weight-loss or pioglitazone is relevant as novel PPAR-γ agonists are being developed for treating NASH.

METHODS: Fifty-five patients with NASH received a -500 kcal/day hypocaloric diet and were randomized (double-blind) to pioglitazone (45 mg/d) or placebo for 6-months. Before and after treatment patients underwent a liver biopsy and measurement of hepatic/peripheral glucose fluxes, hepatic/adipose tissue-IR and, in thirty-five patients, hepatic and VF/SC-fat was measured by magnetic resonance spectroscopy/imaging. Data were examined by multivariable statistical analyses combined with machine-learning techniques (PLS-DA).

RESULTS: Both pioglitazone (despite weight-gain) and placebo (if weight-loss) reduced steatosis but only pioglitazone ameliorated necroinflammation. Using machine-learning PLS-DA showed that the treatment differences induced by a PPAR-γ agonist vs. placebo on metabolic variables and liver histology could be best explained by the increase in adiponectin and a decrease in VF/SC, and to a lesser degree, improvement in OGTT-glucose concentrations and ALT. Decrease in steatosis and disease activity score (ballooning plus lobular inflammation) kept a close relationship with an increase in adiponectin (r=-0.71 and r=-0.44, p< 0.007, respectively) and reduction in VF/SC (r=0.41 and r=0.37, p<0.03, respectively).

CONCLUSIONS: Reduction in VF and improved VF/SC-distribution, combined with an increase in adiponectin, mediate the histological benefits of PPAR-γ action, highlighting the central role of fat metabolism and its distribution on steatohepatitis disease activity in patients with NASH.
