Prevalence of Burnout Among Public Health Professionals: A Systematic Review

CONTEXT

Since the initial outbreak of COVID-19, health professionals-both clinical health care, as well as public health concentrations-have faced tremendous pressures. A growing body of literature indicates the pandemic has magnified already prevalent burnout rates among clinical health professionals and to what extent for public health professionals remains to be determined.

OBJECTIVE

This study purpose is to conduct a systematic review of literature examining burnout prevalence among public health professionals before and during the COVID-19 pandemic-nationally and internationally-with identification of potential risk factors.

DESIGN

We conducted a literature search in PubMed, EMBASE, PsycINFO, SocINDEX, and ClinicalKey since inception through April 4, 2023. Inclusion criteria included peer-reviewed, original research studies (qualitative or quantitative), in English, assessing prevalence of, or risk factors for, burnout in public health professionals. Two authors independently screened abstracts, titles, full report of studies and abstracted data related to burnout. This review was conducted using Joanna Briggs Institute Systematic Reviews guidelines and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines with narrative synthesis. Protocol for this review registered on PROSPERO (CRD42023424468).

RESULTS

Of 3327 health-related articles mentioning burnout, 15 met inclusion criteria (11 quantitative and 4 qualitative) with 10 in international settings and 5 in US majority of quantitative studies were from international settings and only 1 in United States. Seventy-eight percent of studies that included prevalence data, exhibited a burnout prevalence greater than 50% (with a range of 19%-81%). The pandemic likely heightened (13% increase) already elevated burnout prevalence. Major risk factors identified included overwork, lack of support, changing roles, and full-time employment status, though many risk factors had not been studied in the United States.

CONCLUSIONS

Burnout is prevalent among public health professionals, nationally and internationally, and likely heightened by the COVID-19 pandemic. More research is warranted assessing burnout among differing public health concentrations and interventions developed. Public health is an essential framework for protecting and promoting health nationally and internationally, and we need to ensure and support solidity of that framework.

Real-world hepatitis C prevalence and treatment uptake at opioid agonist therapy clinics in Ontario, Canada

Widespread screening for hepatitis C virus (HCV) is necessary for Canada to meet its HCV elimination goals by 2030. People who currently or previously injected drugs are at high risk for HCV. Opioid agonist therapy (OAT, such as methadone and buprenorphine) has been shown to help stabilize the lives of people who are opioid-dependent. The distribution of OAT in North America typically requires daily, weekly, or monthly clinic visits and presents an opportunity for engagement, screening and treatment for those at high-risk of HCV. In this study, HCV screening was conducted by staff at OAT clinics in Ontario from 2016 to 2020 and those with chronic infections were treated on-site with direct-acting antivirals. Point-of-care or dried blood spot (DBS) testing was used for antibodies, DBS or serum for HCV RNA and serum for HCV RNA at SVR12 (sustained virological response). Clinics screened 1954 people (mean age 40 years ±12, 63% male). Forty-five percent were antibody positive, of whom 64% were HCV RNA+. Eighty percent of those RNA+ set an appointment in which 99% attended. Ninety-six percent started treatment with 87% completing treatment. Sixty-eight percent of people who completed treatment submitted a sample for SVR12 testing of which 97% achieved a virological cure. Results suggest that HCV screening and treatment at OAT clinics is feasible, effective and warrants expansion. Data suggest strong treatment adherence due to high rates of SVR12 comparable with other OAT-based HCV treatment programs. The lack of SVR12 sampling could be addressed by either on-site phlebotomy or incentivizing SVR12 sampling.

Modeling intrinsic factors of inclusive engagement in citizen science: Insights from the participants' survey analysis of CSI-COP

Inclusive citizen science, an emerging field, has seen extensive research. Prior studies primarily concentrated on creating theoretical models and practical strategies for diversifying citizen science (CS) projects. These studies relied on ethical frameworks or post-project empirical observations. Few examined active participants' socio-demographic and behavioral data. Notably, none, to our knowledge, explored prospective citizen scientists' traits as intrinsic factors to enhance diversity and engagement in CS. This paper presents a new inclusive CS engagement model based on quantitative analysis of surveys administered to 540 participants of the dedicated free informal education MOOC (Massive Open Online Course) 'Your Right to Privacy Online' from eight countries in the EU funded project, CSI-COP (Citizen Scientists Investigating Cookies and App GDPR compliance). The surveys were filled out just after completing the training stage and before joining the project as active CSs. Out of the 540 participants who completed the surveys analyzed in this study, only 170 (32%) individuals actively participated as CSs in the project. Therefore, the study attempted to understand what characterizes these participants compared to those who decided to refrain from joining the project after the training stage. The study employed descriptive analysis and advanced statistical tests to explore the correlations among different research variables. The findings revealed several important relationships and predictors for becoming a citizen scientist based on the surveys analysis, such as age, gender, culture, education, Internet accessibility and apps usage, as well as the satisfaction with the MOOC, the mode of training and initial intentions for becoming a CS. These findings lead to the development of the empirical model for inclusive engagement in CS and enhance the understanding of the internal factors that influence individuals' intention and actual participation as CSs. The devised model offers valuable insights and key implications for future CS initiatives. It emphasizes the necessity of targeted recruitment strategies, focusing on underrepresented groups and overcoming accessibility barriers. Positive learning experiences, especially through MOOCs, are crucial; enhancing training programs and making educational materials accessible and culturally diverse can boost participant motivation. Acknowledging varying technological proficiency and providing necessary resources enhances active engagement. Addressing the intention-engagement gap is vital; understanding underlying factors and creating supportive environments can transform intentions into active involvement. Embracing cultural diversity through language-specific strategies ensures an inclusive environment for effective contributions.

Accuracy of portable ultrasound for obstetric biometry

OBJECTIVE

We assessed the accuracy of two portable ultrasound machines (PUM) in obtaining fetal biometry and estimating gestational age.

METHODS

We analyzed data from the Fetal Age Machine Learning Initiative, an observational study of pregnant women in the United States and Zambia. Each participant underwent assessment by an experienced sonographer using both a high-specification ultrasound machine (HSUM) and a PUM (either Butterfly iQ or Clarius C3) to measure fetal biometry and calculate estimated gestational age (EGA) at each visit. Through comparison of paired PUM-HSUM scans, we estimated agreement between individual biometry measurements and aggregate gestational age estimates by reporting mean difference, along with intraclass correlation coefficient (ICC) and Bland-Altman plots, adjusting for trend.

RESULTS

881 participants contributed 1386 paired PUM-HSUM ultrasound studies between April and December 2021. PUM studies included 991 Butterfly and 395 Clarius. Gestational age at scan ranged from 7 to 38 weeks. Compared to HSUM, the Butterfly PUM had a mean difference of -0.20 days (95%CI±0.40) in the 1st trimester and -0.68 days (95%CI±0.68) in the 2nd/3rd trimesters. Also compared to HSUM, the Clarius PUM had a mean difference of 0.47 days (95%CI±0.64) in the 1st trimester and -1.67 days (95%CI±0.43) in the 2nd/3rd trimesters. ICCs were 0.989 or greater throughout. Increasing gestational age was associated with increasing error and absolute error. Both PUM devices demonstrated a modest trend toward underestimation of EGA at advancing gestational ages in 2nd/3rd trimester scans, compared to HSUM.

CONCLUSION

Both the Butterfly iQ and Clarius C3 PUM devices were highly accurate in performing fetal biometry in a diverse population from the US and Zambia. This article is protected by copyright. All rights reserved.

Religiosity and type 2 diabetes self-management among Muslims residing in California

Type 2 diabetes (T2D) is a public health issue that needs to be addressed. In the U.S., 11.3% of the population have diabetes. It is estimated that 90-95% of all diabetes cases are T2D cases. One of the best methods to address T2D is self-management. Prior research found a relationship between religiosity and T2D self-management. The purpose of this study was to examine religiosity and T2D self-management. This was a cross-sectional and qualitative study, which included Muslim adults, who have T2D and live in California. We utilized snowballing to recruit participants and the saturation concept to determine the number of participants. Additionally, we used semi-structured design for the interviews and focus groups. We had 30 participants for the interviews (however, only 25 provided demographic data) and 28 for the combined focus groups. Zoom was used to conduct the interviews and two focus groups. The grounded theory was used to deduce themes from the interviews and focus groups. The main themes for religiosity and self-management are Allah sustains life, everything will be ok/hope, faith gives strength, and the role of self within the fate concept. The themes for self-efficacy are diabetes requires new life approach, stress, and Islamic religious practices promote self-management. The main theme for perceived seriousness is taking action and making changes. Our findings provide significant insight about the relationship between religiosity, perceived seriousness, fatalism, and self-efficacy and self-management of T2D. A recommendation based on this study is that providers and health educators should be aware of the different experiences Muslims with T2D face, and tailor recommendations and programs based on that.

Imaging characteristics of idiopathic scleroma: a retrospective case series and review of the literature

BACKGROUND

Idiopathic scleroma (previously coined solitary idiopathic choroiditis or focal scleral nodule) is an innocuous lesion affecting the sclera with intraocular manifestations. It is often the basis of many misdiagnoses such as amelanotic choroidal melanoma, osteoma or metastatic lesions. Patients are often asymptomatic and the course is benign. With increasing use of community based imaging, more of such cases are being identified. This paper is a retrospective case series investigating the multi-modal imaging findings of idiopathic scleroma.

METHODS

A retrospective analysis of prospectively collected data were analysed. Over the course of January 2008-January 2022, 44 patients diagnosed with idiopathic scleroma and imaged with wide-field colour fundus photography, fundus autofluorescence, ocular coherence tomography (OCT) and B-scan ultrasonography. Due to a poor image, only 43 images were included for OCT review. We also reviewed our patient's demographics, symptoms and baseline ophthalmic characteristics upon presentation.

RESULTS

The mean age was 52 years (range 32-79) and there was no predilection towards gender. All lesions were post equatorial with the most common location being inferotemporal (n = 16, 36%); 32 lesions (73%) were yellow on fundus photography. 82% (n = 36/44) of lesions exhibited hyperautoflourescence and 43 lesions (98%) showed hyperechogenicity on B-scan ultrasonography. 100% of lesions originated from the sclera with no lesions showing active inflammation. 20 (47%) lesions had associated blood vessels overlying them on OCT.

DISCUSSION

Idiopathic scleroma is a yellow, hyperautofluorescent, hyperechogeneic scleral lesion that has no signs of active inflammation. These characteristics help define them from other more sinister cause of amelanotic fundal lesions.

Factors Associated with Confidence in Using the Internet to Access Health Information: A Cross-Sectional Data Analysis (Preprint)

BACKGROUND

Confidence in health information access is a measure of the perceived ability to obtain health information. One's beliefs or perceived ability to access health information is particularly important in understanding trends in health care access. Previous literature has found that access to health information is lowest among society's most vulnerable population groups. These groups include older, less educated, and low-income populations. While health confidence has previously been used as a scale to measure health outcomes, additional research is needed describing the demographic factors associated with users' confidence in health information access. This may be a key component of health information seeking that affects beneficial health outcomes such as prevention and treatment.

OBJECTIVE

This study examines the demographic factors associated with the levels of confidence in using the internet to access health information for adults 18 years and older in the United States.

METHODS

Using a cross-sectional design, secondary data from the Health Information National Trends Survey (HINTS) 5, Cycle 3 (2019) were analyzed (N=5374). An ordinal regression stratified by internet use was used to determine the association between demographic characteristics and level of confidence in health information access.

RESULTS

When the internet is the primary source for health information, high school graduates (adjusted odds ratio [AOR] 0.58, 95% CI 0.37-0.89) compared to those with a college degree or more had significantly lower odds of being confident in obtaining health information. In addition, non-Hispanic Asian participants (AOR 0.44, 95% CI 0.24-0.82) compared to non-Hispanic White participants, male participants (AOR 0.72, 95% CI 0.54-0.97) compared to female participants, and those who made between US $20,000-$35,000 annually (AOR 0.55, 95% CI 0.31-0.98) compared to those who made US $75,000 or more annually had significantly lower odds of being confident in obtaining health information via the internet. Moreover, when the internet is the primary source for health information, those with health insurance had significantly higher odds of being confident in obtaining health information (AOR 2.91, 95% CI 1.58-5.34) compared to those who do not have health insurance. Lastly, a significant association was observed between confidence in health information access and primary health information source and frequency of visiting a health care provider.

CONCLUSIONS

Confidence in accessing health information can differ by individual demographics. Accessing health-related information from the internet has become increasingly more common and can provide insight into health information-seeking behaviors. Further exploration of these factors can inform the science of health education by providing deeper insight into improving access to health information for vulnerable populations.

Well-differentiated gastroenteropancreatic G3 NET: findings from a large single centre cohort

Neuroendocrine neoplasms are known to have heterogeneous biological behavior. G3 neuroendocrine tumours (NET G3) are characterized by well-differentiated morphology and Ki67 > 20%. The prognosis of this disease is understood to be intermediate between NET G2 and neuroendocrine carcinoma (NEC). Clinical management of NET G3 is challenging due to limited data to inform treatment strategies. We describe clinical characteristics, treatment, and outcomes in a large single centre cohort of patients with gastroenteropancreatic NET G3. Data was reviewed from 26 cases managed at Queen Elizabeth Hospital, Birmingham, UK, from 2012 to 2019. Most commonly the site of the primary tumour was unknown and majority of cases with identifiable primaries originated in the GI tract. Majority of cases demonstrated somatostatin receptor avidity. Median Ki67 was 30%, and most cases had stage IV disease at diagnosis. Treatment options included surgery, somatostatin analogs (SSA), and chemotherapy with either platinum-based or temozolomide-based regimens. Estimated progression free survival was 4 months following initiation of SSA and 3 months following initiation of chemotherapy. Disease control was observed following treatment in 5/11 patients treated with chemotherapy. Estimated median survival was 19 months; estimated 1 year survival was 60% and estimated 2 year survival was 13%. NET G3 is a heterogeneous group of tumours and patients which commonly have advanced disease at presentation. Prognosis is typically poor, though select cases may respond to treatment with SSA and/or chemotherapy. Further study is needed to compare efficacy of different treatment strategies for this disease.

Structural brain lesions in schizophrenia -magnetic resonance imaging on a mid field magnet

Objectives : The brain damage associated with schizophrenia has been established beyond doubt; however, what remains unexplored is the biological nature of transcultural variations. An important reason for this was the lack of mid and high field scanners in developing countries like India. Material and Methods : We undertook a pilot study using a 0.5 Tesla MRI scanner (General Electric Signa Contour) to explore identifiable structural brain lesions in ten randomly selected individuals with schizophrenia. Results: Nine of the ten participants in the series had structural brain changes. The most common findings were ventricular dilatation and prominent cerebral cortical sulci and cerebellar folia. Additionally non-focal white matter lesions were observed in three patients and small right hippocampus was noted in one participant. Conclusions : The study discusses that establishing structural brain lesions with mid field scanners is indeed feasible. The small study sample and heterogeneity of schizophrenia however made it difficult to establish any definite associations

75 Treatment Escalation Plan (TEP) Completion Rates in General Surgery

Background

TEPs ensure every patient has a ceiling of care formally documented, including a DNACPR decision. This pre-empts complications and provides guidance on how to appropriately manage acutely unwell patients. There is no national standard for TEPs. Our aim: to formally document the incidence of TEP completion in general surgery at a local District General Hospital.

Method

A multi-phase, cross-sectional study of 1. Inpatients on three general surgical wards, 2. TEP completion at post-take after a typical on-call cycle.

Results

15.4% of TEPs were completed, of which 75% had a DNARCPR form. For the two post-take ward rounds, 5% and 7.7% of admitted patients had a TEP. Elective surgical/Enhanced recovery patients (ERP) did not have a TEP. Findings were presented locally, and posters placed in the surgical offices. Cycle 2: 19.6% and 10% completion rate for ward and post-take patients, respectively.

Conclusions

TEPs are rarely completed. Minimal improvement in completion rate was noted at cycle 2. TEPs are more commonly completed for patients not for resuscitation. Future aims include editing the surgical clerking proforma and the elective surgery/ERP paperwork to encourage completion, improving patient care. Currently we are arranging similar audits across other NHS trusts to determine if this is a national problem.

Comparison of pulmonary vein sizing by transesophageal echocardiogram and by direct angiogram

Funding Acknowledgements

Type of funding sources: None.

Background

Pulmonary vein (PV) anatomy and sizing is important to know before performing PV isolation. This information is conventionally obtained by angiography or by CT scan.

Aim

We undertook this study to identify and measure the PVs during TEE studies and validate these against angiography.

Method

17 consecutive patients due to undergo PV isolation for paroxysmal atrial fibrillation were analysed. Using TEE, the PVs were visualised (Upper panel) as follows:  i) From the mid-esophageal four chamber view, the chamber probe was turned to the right at 110-130º for the bicaval view, where the RSPV was seen entering the left atrium adjacent to the SVC. ii) At 0º the SVC was imaged in its short axis, and the probe advanced till the interatrial septum was seen. The angle was changed to 30º to visualise the right inferior PV (RIPV). iii) From the two chamber view (70-90º), the probe was turned to the left and withdrawn to display the left superior PV (LSPV) entering the left atrium parallel to the appendage.iv) Keeping the LSPV in focus, the angle was changed to 135º and the probe advanced till the AV groove, where the left inferior PV (LIPV) was visualised. After transseptal puncture, each PV was cannulated. The PV angiograms were performed in several projections to obtain the best PV profile (lower panel). Using electronic callipers, each PV was measured within 1 cm of its entry into the left atrium, after having received all tributaries. Those PVs were considered for analysis which were measured by both TEE and angiography. The paired ‘T’ test was used to compare the PV diameters by TEE and angiography and the Bland Altman analysis was done to see the level of agreement.

Results

Of a total of 68 PVs, 62 could be adequately visualised by TEE and 50 by angiography. These 50 PVs were measured using both methods. The diameters of the PVs measured by TEE and angiography were not statistically different by the paired t test; LSPV14 ± 1.8 mm v/s 14.4 ± 2.1 mm; RSPV 13 ± 1.8 mm v/s 14.6 ± 3.5 mm; LIPV 11.9 ± 2.1 vs 13.2 ± 2.8 mm and RIPV 10.5 ± 2.7 vs 12.1 ± 2.9 mm. Bland Altman analysis showed most PV sizes estimated by TEE and angiography lay within limits of agreement.

Conclusions

A majority of PVs can be visualised by TEE using a defined protocol. TEE is a good technique to visualise and assess the size of PVs, avoiding the need for contrast medium and radiation.

Meaningful Use of Electronic Health Records and Ambulatory Healthcare Quality Measures

Introduction

Electronic Health Record (EHR) adoption rates for office-based physicians doubled between 2008 and 2015, from 42% to 89%, and more than 60% of all office-based physicians achieved meaningful use by 2016. The US government has paid billions of dollars in incentives to promote EHR meaningful use. Nonetheless, evidence linking EHR meaningful use to quality measures improvements is limited.

Objective

This study aims to examine the relationship between EHR meaningful use and capabilities among four quality measures in an ambulatory healthcare setting.

Study design

A cross-sectional study design of the 2015-2016 National Ambulatory Medical Care Survey dataset.

Methods

We used adjusted multivariate regression models to examine associations between (a) EHR meaningful use and (b) 10 EHR-computerized capabilities, with four quality measures (blood pressure screening, tobacco use screening, obesity screening, and obesity education).

Results

We analyzed 30,787 office visits, representing an annual estimate of 680 million national office visits. Results showed that 95% of visits were to offices meeting EHR meaningful use criteria. We found one positive association between EHR meaningful use and obesity screening (OR= 3.5, 95% CI [1.742-6.917]). We also found eight positive associations between EHR capabilities and three quality measures (screening for blood pressure and obesity, and obesity education). These associations included five EHR-computerized capabilities: “record patient problem list”, “view lab results”, “Reminders for interventions/screening”, “Order lab results” and “Recording clinical notes”. No EHR capability was associated with screening for tobacco use.

Conclusions

We looked at a handful of screening-oriented quality measures in ambulatory healthcare and found limited associations with EHR meaningful use but multiple positively significant associations with EHR capabilities. Although EHR meaningful use has become more commonly used, offering substantial administrative efficiency over paper records, current patterns of EHR meaningful use do not always appear to translate into a better quality of care in physician offices. However, quality measures used represent limited procedures for a handful of specific conditions and not the overall healthcare aspect.

Social network analysis of COVID-19 transmission in Karnataka, India

We used social network analysis (SNA) to study the novel coronavirus (COVID-19) outbreak in Karnataka, India, and to assess the potential of SNA as a tool for outbreak monitoring and control. We analysed contact tracing data of 1147 COVID-19 positive cases (mean age 34.91 years, 61.99% aged 11-40, 742 males), anonymised and made public by the Karnataka government. Software tools, Cytoscape and Gephi, were used to create SNA graphics and determine network attributes of nodes (cases) and edges (directed links from source to target patients). Outdegree was 1-47 for 199 (17.35%) nodes, and betweenness, 0.5-87 for 89 (7.76%) nodes. Men had higher mean outdegree and women, higher mean betweenness. Delhi was the exogenous source of 17.44% cases. Bangalore city had the highest caseload in the state (229, 20%), but comparatively low cluster formation. Thirty-four (2.96%) 'super-spreaders' (outdegree ⩾ 5) caused 60% of the transmissions. Real-time social network visualisation can allow healthcare administrators to flag evolving hotspots and pinpoint key actors in transmission. Prioritising these areas and individuals for rigorous containment could help minimise resource outlay and potentially achieve a significant reduction in COVID-19 transmission.

P636 A unique case of purulent pericarditis resulting in cardiac tamponade

Introduction and case report description

A 54-year-old male with no past cardiac disease was experiencing a productive cough, fevers, chills, and shortness of breath for 3 days in the community. His dyspnea worsened significantly, and he then presented to the emergency room. He admitted to using intravenous recreational drugs. His initial vital signs included a temperature of 38.2 degrees Celsius, a heart rate of 116 beats per minute, and a blood pressure of 88/42 mmHg. He had a positive pulses paradoxus with a decrease in systolic blood pressure of 14 mmHg on inspiration.

Description of the problem and procedures

This presentation was consistent with cardiac tamponade. He had an emergent echocardiogram showing a large pericardial effusion in the apical-four-chamber view (Image 1, A), including collapse of the right ventricle during diastole (Image 1, B, Green Arrow). There were also fibrin strands seen in a modified parasternal long axis view (Image 1, C, Blue Arrow). He had an emergency pericardiocentesis using real-time ultrasound guidance, which drained 400 mL of thick brown purulent fluid. A pigtail catheter was inserted to allow for continued drainage. Immediately afterwards, the patient’s blood pressure normalized, and his shortness of breath improved significantly.

Using the ultrasound, the physician also saw bilateral pleural effusions. The larger left pleural effusion was drained, and a pigtail catheter was inserted into the left pleural space. After confirming that there was no post-procedure left pneumothorax, the right pleural effusion was also drained.

An echocardiogram after the pericardiocentesis showed a significant decrease in the size of the pericardial effusion (Image 1, D).

The patient was started on broad-spectrum antibiotics, which was then narrowed after cultures from both the pericardial fluid and pleural fluid grew methicillin-susceptible Staphylococcus aureus.

Discussion

Cardiac tamponade results in increased compression of the cardiac chambers due to raised pericardial pressures. As it progresses, it can result in significant impairment in venous return, cardiac output, and blood pressure. This is a life-threatening condition if it is not promptly treated. In this case, the patient had a methicillin-susceptible Staphylococcus aureus empyema which spread contiguously into the pericardium and resulted in cardiac tamponade.

Conclusions and implications for clinical practice

This case highlights the clinical benefits of being proficient in performing a point-of-care ultrasound because a bedside echocardiogram by the physician immediately confirmed the diagnosis and allowed for safer drainage of the pericardial effusion using ultrasound guidance to decrease the chance of causing a perforation of the ventricle. Using ultrasound, the clinician was also able to promptly diagnose the pleural effusions and urgently drain them, which was necessary for achieving source control in order to fully treat the infection.

A review of skeletal dysplasia research in India

We aimed to review the contributions by Indian researchers to the subspecialty of skeletal dysplasias (SDs). Literature search using specific keywords in PubMed was performed to retrieve all the published literature on SDs as on July 6, 2017. All published literature on SDs wherein at least one author was from an Indian institute was included. Publications were grouped into different categories based on the major emphasis of the research paper. Five hundred and forty publications in English language were retrieved and categorized into five different groups. The publications were categorized as reports based on: (i) phenotypes (n = 437), (ii) mutations (n = 51), (iii) novel genes (n = 9), (iv) therapeutic interventions (n = 31), and (v) reviews (n = 12). Most of the publications were single-patient case reports describing the clinical and radiological features of the patients affected with SDs (n = 352). We enlisted all the significant Indian contributions. We have also highlighted the reports in which Indians have contributed to discovery of new genes and phenotypes. This review highlights the substantial Indian contributions to SD research, which is poised to reach even greater heights given the size and structure of our population, technological advances, and expanding national and international collaborations.

Bold leadership is needed for transforming health care

Health care in the United States is going through significant changes and is at the forefront of the political landscape. While the health care debate rages on, leaders need to forge ahead and continue to work towards population-based health care and investing in their communities in a fiscally conscious way. Many innovations are happening but more needs to be done, especially in upstream services improving the health of the community. Research shows that investing in social care services and community-based investments results in lower health care expenditures and better health outcomes. Efforts should be placed on exploring a blended medical/social model of care while considering blended funding sources wherein the community needs to be active participants in this explorative process.

Association of Covered California and Healthcare Access and Utilization among Latino Population

Background and Purpose: The Patient Protection and Affordable Care Act resulted in establishment of Covered California (Covered CA), a marketplace providing federally subsidized health insurance in California. This study explored whether obtaining Covered CA coverage improves healthcare access and utilization among Latinos, and whether acculturation plays a role in utilization of healthcare. Methods: 270 Latino adults in San Diego community completed a self-report survey. Results: Those with Covered CA were significantly more likely to have a main provider (p

Seven additional families with spondylocarpotarsal synostosis syndrome with novel biallelic deleterious variants in FLNB

The location and/or type of variants in FLNB result in a spectrum of osteochondrodysplasias ranging from mild forms, like spondylocarpotarsal synostosis syndrome and Larsen syndrome, to severe perinatal lethal forms, such as atelosteogenesis I and III and Boomerang dysplasia. Spondylocarpotarsal synostosis syndrome is characterized by disproportionate short stature, vertebral anomalies and fusion of carpal and tarsal bones. Biallelic loss-of-function variants in FLNB are known to cause spondylocarpotarsal synostosis syndrome and 9 families and 9 pathogenic variants have been reported so far. We report clinical features of 10 additional patients from 7 families with spondylocarpotarsal synostosis syndrome due to 7 novel deleterious variants in FLNB, thus expanding the clinical and molecular repertoire of spondylocarpotarsal synostosis syndrome. Our report validates key clinical (fused thoracic vertebrae and carpal and tarsal coalition) and molecular (truncating variants in FLNB) characteristics of this condition.

Alpha galactosidase A activity in Parkinson's disease

Glucocerebrosidase (GCase, deficient in Gaucher disease) enzymatic activity measured in dried blood spots of Parkinson's Disease (PD) cases is within healthy range but reduced compared to controls. It is not known whether activities of additional lysosomal enzymes are reduced in dried blood spots in PD. To test whether reduction in lysosomal enzymatic activity in PD is specific to GCase, we measured GCase, acid sphingomyelinase (deficient in Niemann-Pick disease types A and B), alpha galactosidase A (deficient in Fabry), acid alpha-glucosidase (deficient in Pompe) and galactosylceramidase (deficient in Krabbe) enzymatic activities in dried blood spots of PD patients (n = 648) and controls (n = 317) recruited from Columbia University. Full sequencing of glucocerebrosidase (GBA) and the LRRK2 G2019S mutation was performed. Enzymatic activities were compared between PD cases and controls using t-test and regression models adjusted for age, gender, and GBA and LRRK2 G2019S mutation status. Alpha galactosidase A activity was lower in PD cases compared to controls both when only non-carriers were included (excluding all GBA and LRRK2 G2019S carriers and PD cases with age-at-onset below 40) [2.85 μmol/l/h versus 3.12 μmol/l/h, p = 0.018; after controlling for batch effect, p = 0.006 (468 PD cases and 296 controls)], and when including the entire cohort (2.89 μmol/l/h versus 3.10 μmol/l/h, p = 0.040; after controlling for batch effect, p = 0.011). Because the alpha galactosidase A gene is X-linked, we stratified the analyses by sex. Among women who were non-carriers of GBA and LRRK2 G2019S mutations (PD, n = 155; control, n = 194), alpha galactosidase A activity was lower in PD compared to controls (2.77 μmol/l/h versus 3.10 μmol/l/h, p = 0.044; after controlling for a batch effect, p = 0.001). The enzymatic activity of acid sphingomyelinase, acid alpha-glucosidase and galactosylceramidase was not significantly different between PD and controls. In non-carriers, most lysosomal enzyme activities were correlated, with the strongest association in GCase, acid alpha-glucosidase, and alpha galactosidase A (Pearson correlation coefficient between 0.382 and 0.532). In a regression model with all five enzymes among non-carriers (adjusted for sex and age), higher alpha galactosidase A activity was associated with lower odds of PD status (OR = 0.54; 95% CI:0.31-0.95; p = 0.032). When LRRK2 G2019S PD carriers (n = 37) were compared to non-carriers with PD, carriers had higher GCase, acid sphingomyelinase and alpha galactosidase A activity. We conclude that alpha galactosidase A may have a potential independent role in PD, in addition to GCase.

Role of Central Corneal Thickness on Baseline Parameters and Progression of Visual Fields in Open Angle Glaucoma

Purpose

To evaluate the relationship of central corneal thickness (CCT) to baseline visual field parameters and visual field progression in patients with primary open-angle glaucoma (POAG).

Methods

Charts of consecutive patients with POAG were reviewed to obtain visual field data. Visual field was measured by standard threshold static perimetry. Variables analyzed included mean deviation (MD) and pattern standard deviation (PSD).

Results

A total of 121 eyes examined over 4 years were evaluated. A significant negative relationship between CCT and PSD (correlation coefficient: −0.02, p<0.05) was found. Analyses comparing CCT to change in PSD and MD (visual field progression) were statistically not significant.

Conclusions

Patients with thinner corneas initially present with a greater visual field defect, indicating that thin corneas may contribute to advanced glaucomatous damage at the time of diagnosis. However, CCT does not seem to be a significant risk factor for progression of the disease.

Neurenteric cyst of the conus medullaris

Background:

Neurenteric cysts (NECs) are rare developmental malformations of the central nervous system (CNS) which originate as benign congenital lesions. They originate from developmental foregut precursors, and are presumed to be the result of abnormal partitioning of the embryonic notochord plate. Such NECs predominantly arise in the cervical region in patients around 6 years of age or in their twenties or thirties. Notably, NECs of the conus medullaris are exceedingly rare, especially in patients of advanced age.

Case Description:

A 70-year-old male presented with bilateral upper thigh and leg pain of over 20 years duration. His pain worsened over the past 3 years, and he sought surgical management. Although his neurological exam was normal, the lumbar magnetic resonance imaging revealed an intradural, nonenhancing, thin-walled, cystic lesion at L1/conus medullaris. The lesion was successfully resected without any adverse sequelae.

Conclusions:

NECs are rare congenital legions that involve the spine. Here, an L1 intradural extramedullay neuroenteric cyst of the conus medullaris was resected without complications.

Post-prophylaxis Toxoplasma chorioretinitis following donor-recipient mismatched liver transplantation

Toxoplasmosis may be transferred by organ transplantation. The most common clinical presentation is with multisystem disease, although isolated ocular toxoplasmosis has been described. Many centers have suggested that universal use of co-trimoxazole prophylaxis obviates the need for specific Toxoplasma testing. We report a case of donor-acquired ocular toxoplasmosis after liver transplantation despite co-trimoxazole prophylaxis. The diagnosis was confirmed by Toxoplasma polymerase chain reaction assay in conjunction with seroconversion. The fact that the infection was donor acquired was confirmed by serological mismatch and the absence of sporozoite-specific antigen antibody in the recipient.

Second family provides further evidence for causation of Steel syndrome by biallelic mutations in COL27A1

Steel syndrome is a rare disorder of the skeleton characterized by facial dysmorphism, short stature, carpal coalition, dislocated radial heads, bilateral hip dislocation and vertical talus. Homozygous variants in COL27A1 were reported in an extending family from Puerto Rico. Here, we report a 5-year-old girl from a non-consanguineous family with facial dysmorphism, short stature, carpal coalition, dislocation of radial heads, bilateral hip dislocation, scoliosis and vertical talus. Exome sequencing identified 2 novel compound heterozygous variants c.521_528del (p.(Cys174Serfs*34)) and c.2119C>T (p.(Arg707*)) in COL27A1 in this child and the parents were heterozygous carriers. We hence report the second molecularly proven case of Steel syndrome and the first case to be reported among non-Puerto Rican population. Our report further validates the role of COL27A1 mutations in causation of Steel syndrome.
