Patient tracking during treatment of children with cancer in India - An exploratory study

BACKGROUND

Abandonment of treatment, a major cause of treatment failure in low- and middle-income countries like India, is particularly high during the diagnostic and initial phase of treatment. Tracking of patients during this risk period may reduce treatment abandonment rates and increase quality of care.

AIM

The primary aim was to pilot the use and check the acceptability of a tool for tracking children with cancer in New Delhi during the initial part of their treatment. Secondary aim was to estimate abandonment rates among these patients.

METHODS

This prospective study was carried out in two centers of North India in New Delhi and enrolled children less than 18 years diagnosed with cancer at these centers and who had registered with Cankids for social support. Parent support group (PSG) workers maintained contact with the child's family at least once a week for the first 12 weeks. Details of each contact and subsequent action were recorded in a customized book (called "You are not alone" or YANA Book). Descriptive analysis of these contacts was done in Microsoft Excel and presented in frequencies and percentages. The five-point Likert scale was used to check the acceptability of the tool among the PSG workers.

RESULTS

Seven PSG workers enrolled and tracked 81 patients (73% male with a median age of 6 years). During the 12-week study period, 986 contacts were attempted and three (3.7%) patients had abandoned their treatment. All PSG workers strongly agreed that the YANA book was simple to understand and use, decreased their workload, and helped provide better assistance to patients.

CONCLUSION

The tool for patient tracking was well accepted by the PSG workers and considered easy to use. We now plan to implement our model as a routine service at all the partnering hospitals in India.

Summary of 3rd Sino-German symposium on fundamentals of advanced nuclear safety technology

The 3rd "Sino-German Symposium on Fundamentals of Advanced Nuclear Safety Technology (SG-FANS)" took place in Xi’an, China, in 2019. Common fields of interests have been identified on both Chinese and German side, such as code benchmarking, common access to experimental facilities and joint experimental data base for nuclear safety analyses.

Effect of postprandial triglycerides on DDT/ppDDE levels in subjects with varying degree of glucose intolerance

BACKGROUND

Organochlorine pesticides such as DDT as well as postprandial hypertriglyceridemia have been linked with insulin resistance and diabetes mellitus. The cardiometabolic risk of PPhTg could also be due to its potential to increase the serum levels of this highly lipophilic pesticide. We studied the effect of postprandial triglyceride responses to a standard oral fat challenge on the levels of DDT and its metabolites in subjects with varying degree of glucose intolerance METHODS: A standard fat challenge was performed in 60 subjects who were categorized as NGT, prediabetes, and NDDM based on an earlier OGTT. Fasting and postprandial levels of serum triglycerides, plasma DDT and its metabolites were estimated and compared in the 3 groups and their association with each other, and measures of glycemia and insulin resistance were also determined.

RESULTS

Peak Tg and TgAUC levels were significantly higher in NDDM group as compared to NGT and PD groups. TgAUC showed positive correlation with fasting plasma glucose (r=0.33, p=0.01), postprandial plasma glucose (r=0.39, p=0.002) and HOMA IR(r=0.63, p=0.001). ppDDE levels were found to be significantly higher in NDDM subjects compared with NGT group. ppDDE-AUC was significantly higher in the NDDM group compared with the other two study groups. Mean ppDDE levels also showed strong positive correlation with peak Tg (r=0.295 p=0.022), TgAUC (r=0.303 p=0.018), iPPTgAUC(r=0.57 p≤0.001) and iPPpeakTg(r=0.51 p≤0.001) as well as with FPG (r=0.269 p=0.038) PPPG (r=0.424 p=0.001) and HbA1c (r=0.321 p=0.012).

CONCLUSION

The findings of this study support the concept that the cardiometabolic risk associated with PPhTg may at least in part be related to the associated increase in serum levels of lipophilic OCPs like DDT.

SARS-CoV-2 Detection in Gingival Crevicular Fluid

Understanding the pathophysiology of the coronavirus disease 2019 (COVID-19) infection remains a significant challenge of our times. The gingival crevicular fluid being representative of systemic status and having a proven track record of detecting viruses and biomarkers forms a logical basis for evaluating the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The study aimed to assess gingival crevicular fluid (GCF) for evidence of SARS-CoV-2 in 33 patients who were deemed to be COVID-19 positive upon nasopharyngeal sampling. An attempt was also made to comparatively evaluate it with saliva in terms of its sensitivity, as a diagnostic fluid for SARS-CoV-2. GCF and saliva samples were collected from 33 COVID-19-confirmed patients. Total RNA was extracted using NucliSENS easyMAG (bioMérieux) and eluted in the elution buffer. Envelope gene (E gene) of SARS-CoV-2 and human RNase P gene as internal control were detected in GCF samples by using the TRUPCR SARS-CoV-2 RT qPCR kit V-2.0 (I) in an Applied Biosystems 7500 real-time machine. A significant majority of both asymptomatic and mildly symptomatic patients exhibited the presence of the novel coronavirus in their GCF samples. Considering the presence of SARS-CoV-2 RNA in the nasopharyngeal swab sampling as gold standard, the sensitivity of GCF and saliva, respectively, was 63.64% (confidence interval [CI], 45.1% to 79.60%) and 64.52% (CI, 45.37% to 80.77%). GCF was found to be comparable to saliva in terms of its sensitivity to detect SARS-CoV-2. Saliva samples tested positive in 3 of the 12 patients whose GCF tested negative, and likewise GCF tested positive for 2 of the 11 patients whose saliva tested negative on real-time reverse transcription polymerase chain reaction. The results establish GCF as a possible mode of transmission of SARS-CoV-2, which is the first such report in the literature, and also provide the first quantifiable evidence pointing toward a link between the COVID-19 infection and oral health.

The Mars 2020 Perseverance Rover Mast Camera Zoom (Mastcam-Z) Multispectral, Stereoscopic Imaging Investigation

Mastcam-Z is a multispectral, stereoscopic imaging investigation on the Mars 2020 mission's Perseverance rover. Mastcam-Z consists of a pair of focusable, 4:1 zoomable cameras that provide broadband red/green/blue and narrowband 400-1000 nm color imaging with fields of view from 25.6° × 19.2° (26 mm focal length at 283 μrad/pixel) to 6.2° × 4.6° (110 mm focal length at 67.4 μrad/pixel). The cameras can resolve (≥ 5 pixels) ∼0.7 mm features at 2 m and ∼3.3 cm features at 100 m distance. Mastcam-Z shares significant heritage with the Mastcam instruments on the Mars Science Laboratory Curiosity rover. Each Mastcam-Z camera consists of zoom, focus, and filter wheel mechanisms and a 1648 × 1214 pixel charge-coupled device detector and electronics. The two Mastcam-Z cameras are mounted with a 24.4 cm stereo baseline and 2.3° total toe-in on a camera plate ∼2 m above the surface on the rover's Remote Sensing Mast, which provides azimuth and elevation actuation. A separate digital electronics assembly inside the rover provides power, data processing and storage, and the interface to the rover computer. Primary and secondary Mastcam-Z calibration targets mounted on the rover top deck enable tactical reflectance calibration. Mastcam-Z multispectral, stereo, and panoramic images will be used to provide detailed morphology, topography, and geologic context along the rover's traverse; constrain mineralogic, photometric, and physical properties of surface materials; monitor and characterize atmospheric and astronomical phenomena; and document the rover's sample extraction and caching locations. Mastcam-Z images will also provide key engineering information to support sample selection and other rover driving and tool/instrument operations decisions.

Practical consensus recommendations on ovarian suppression in early breast cancer (adjuvant)

Substantial survival benefits exist for patients with early-stage breast cancer who undergo treatment with single-modality ovarian suppression, but its value is uncertain. Expert oncologist discussed to determine whether additional benefits exist with ovarian suppression plus multiple adjuvant therapy which provides a new treatment option that reduces the risk of recurrence in early breast cancer. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at this practical consensus recommendations for the benefit of community oncologists.

Practical consensus recommendations on management of HR + ve early breast cancer with specific reference to genomic profiling

Breast cancer is a heterogeneous disease and patients are managed clinically based on ER, PR, HER2 expression, and key risk factors. The use of gene expression assays for early stage disease is already common practice. These tests have found a place in risk stratifying the heterogeneous group of stage I–II breast cancers for recurrence, for predicting chemotherapy response, and for predicting breast cancer-related mortality. Most guidelines for hormone receptor (HR)–positive early breast cancer recommend addition of adjuvant chemotherapy for most women, leading to overtreatment, which causes considerable morbidity and cost. Expert oncologist discussed about strategies of gene expression assays and aid in chemotherapy recommendations for treatment of HR + ve EBC and the expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at this practical consensus recommendations for the benefit of community oncologists.

Practical consensus recommendations regarding the management of hormone receptor positive early breast cancer in elderly women

Breast cancer is a leading cause of death among women, and its incidence increases with age. Currently the treatment of breast cancer in older patients is almost identical to their younger counterparts. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations for the benefit of community oncologists regarding the management of early breast cancer specifically in elderly women.

Practical consensus recommendations on duration of adjuvant hormonal therapy in breast cancer

Optimization of adjuvant systemic therapy in women with early-stage hormone receptor-positive breast cancer includes the consideration of chemotherapy and duration of hormone therapy. Adjuvant hormonal therapy significantly improves long-term survival of breast cancer patients with hormone receptor-positive disease. Despite the proven clinical efficacy of tamoxifen and aromatase inhibitors, many breast cancer survivors either fail to take the correct dosage at the prescribed frequency (adherence) or discontinue therapy (persistence). Expert oncologist discussed on the duration of adjuvant hormonal therapy for improvement of OS and quality of life of breast cancer patients by providing reduction in recurrence and mortality. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at this practical consensus recommendations for the benefit of community oncologists.

Evidence for a Diagenetic Origin of Vera Rubin Ridge, Gale Crater, Mars: Summary and Synthesis of Curiosity's Exploration Campaign

This paper provides an overview of the Curiosity rover's exploration at Vera Rubin ridge (VRR) and summarizes the science results. VRR is a distinct geomorphic feature on lower Aeolis Mons (informally known as Mount Sharp) that was identified in orbital data based on its distinct texture, topographic expression, and association with a hematite spectral signature. Curiosity conducted extensive remote sensing observations, acquired data on dozens of contact science targets, and drilled three outcrop samples from the ridge, as well as one outcrop sample immediately below the ridge. Our observations indicate that strata composing VRR were deposited in a predominantly lacustrine setting and are part of the Murray formation. The rocks within the ridge are chemically in family with underlying Murray formation strata. Red hematite is dispersed throughout much of the VRR bedrock, and this is the source of the orbital spectral detection. Gray hematite is also present in isolated, gray-colored patches concentrated toward the upper elevations of VRR, and these gray patches also contain small, dark Fe-rich nodules. We propose that VRR formed when diagenetic event(s) preferentially hardened rocks, which were subsequently eroded into a ridge by wind. Diagenesis also led to enhanced crystallization and/or cementation that deepened the ferric-related spectral absorptions on the ridge, which helped make them readily distinguishable from orbit. Results add to existing evidence of protracted aqueous environments at Gale crater and give new insight into how diagenesis shaped Mars' rock record.

Complication rate among people with diabetes at low risk of foot ulceration in Fife, UK: an analysis of routinely collected data

AIMS

To estimate the rate at which people with diabetes and a low risk of foot ulceration change diabetic foot ulceration risk status over time, and to estimate the rate of ulceration, amputation and death among this population.

METHODS

We conducted an observational study of 10 421 people with diabetes attending foot screening in an outpatient setting in NHS Fife, UK, using routinely collected data from a national diabetes register, NHS SCI Diabetes. We estimated the proportion of people who changed risk status and the cumulative incidence of ulceration, amputation and death, respectively, among people with diabetes at low risk of diabetic foot ulceration at 2-year follow-up.

RESULTS

At 2-year follow-up, 5.1% (95% CI 4.7, 5.6) of people with diabetes classified as low risk at their first visit had progressed to moderate risk. The cumulative incidence of ulceration, amputation and death was 0.4% (95% CI 0.3, 0.6), 0.1% (95% CI 0.1, 0.2) and 3.4% (95% CI 3.1, 3.8), respectively.

CONCLUSIONS

At 2-year follow-up, 5% of people at low risk of diabetic foot ulceration changed clinical risk status and <1% of people experienced foot ulceration or amputation. These findings provide information which will help to inform the current debate regarding optimal foot screening intervals.

Structure of an affinity-matured inhibitory recombinant fab against urokinase plasminogen activator reveals basis of potency and specificity

Affinity maturation of U33, a recombinant Fab inhibitor of uPA, was used to improve the affinity and the inhibitory effect compared to the parental Fab. Arginine scanning of the six CDR loops of U33 was done to identify initial binding determinants since uPA prefers arginine in its primary substrate binding pocket. Two CDR loops were selected to create an engineered affinity maturation library of U33 that was diversified around ArgL91 (CDR L3) and ArgH52 (CDR H2). Biopanning of the randomized U33 library under stringent conditions resulted in eight Fabs with improved binding properties. One of the most potent inhibitors, AB2, exhibited a 13-fold decrease in IC50 when compared to U33 largely due to a decrease in its off rate. To identify contributions of interfacial residues that might undergo structural rearrangement upon interface formation we used X-ray footprinting and mass spectrometry (XFMS). Four residues showed a pronounced decrease in solvent accessibility, and their clustering suggests that AB2 targets the active site and also engages residues in an adjacent pocket unique to human uPA. The 2.9 Å resolution crystal structure of AB2-bound to uPA shows a binding mode in which the CDR L1 loop inserts into the active site cleft and acts as a determinant of inhibition. The selectivity determinant of this binding mode is unlike previously identified inhibitory Fabs against uPA related serine proteases, MTSP-1, HGFA and FXIa. CDRs H2 and L3 loops aid in interface formation and provide critical salt-bridges to remodel loops surrounding the active site of uPA providing specificity and further evidence that antibodies can be potent and selective inhibitors of proteolytic enzymes.

Endoscopic management of pleural effusion caused by a pancreatic pleural fistula

Pancreatic-pleural fistula (PPF) is a rare sequela of pancreatitis. High degree of clinical suspicion is required to diagnose a PPF. Confirmation is done by high amylase content in pleural fluid analysis. Here, we present two cases with varied presentation of PPF. A 43-year-old man presented with acute on chronic pancreatitis with bilateral (predominantly right) pleural effusion. Another 57-year-old man, previously diagnosed with chronic calcific pancreatitis, presented with left pleural effusion. Both cases were effectively managed with endoscopic pancreatic duct stenting.

Survival Disparities of Diffuse Large B-Cell Lymphoma in a Community-Based Inner-City Cancer Center

BACKGROUND

Diffuse large B-cell lymphoma (DLBCL) comprises approximately 30% of all non-Hodgkin lymphomas. Multiple studies have demonstrated race-based disparities in survival among patients with DLBCL across all stages of disease, in the era both before and after rituximab. The etiology for the racial disparities in survival among patients with DLBCL is still unknown. Moreover, the Revised International Prognostic Index (R-IPI), a tool that predicts the DLBCL patients' outcome, has not yet been validated in African Americans (AA).

PATIENTS AND METHODS

We conducted a cohort study of patients diagnosed with DLBCL from January 1, 2007, to December 31, 2017, from our tumor registry in a single community-based inner-city cancer center. We abstracted demographic, clinical, histopathologic, treatment, and R-IPI variables. A total of 181 patients (47.5%) with biopsy-proven DLBCL were included in the retrospective analysis. The median age was 65 years, 47% were men, 41% were AA, and 44% were white.

RESULTS

The AA group had a younger median age, higher lactate dehydrogenase levels, higher frequency of B symptoms, and higher HIV infection than the non-AA group. The AA group had significantly decreased median overall survival than the non-AA group (15.7 months; 95% confidence interval, 10.3 to 23.9, vs. 93.6 months; 95% confidence interval, 61.5 to 142.6, respectively; P < .001). The survival disparities persisted after excluding patients with HIV and who did not receive chemotherapy. In addition, AA race predicts a reduced survival by univariate and multivariate analysis.

CONCLUSION

AA with DLBCL may have a poorer prognosis than the non-AA population. Further studies should investigate the biology of DLBCL in the AA population.

Anticoagulation for mechanical aortic valve replacement: an international survey

Introduction

Mechanical valves are preferred over biologic valves in younger patients because they are more durable but require long-term anticoagulation which increases the risk of bleeding. For patients with a mechanical aortic valve, the ACCP guidelines recommend a target INR of 2.5 (range 2.0–3.0) for all patients, whereas the ACC/AHA and ESC guidelines recommend a higher target for selected patients with additional risk factors for thromboembolism (TE). Data supporting the guideline recommendations are largely historical and of low quality.

Purpose

We surveyed physicians who manage anticoagulation for patient with mechanical heart valves to determine their usual practice, perceptions regarding guideline recommendations, and interest in participating in a randomized controlled trial (RCT) comparing lower with higher INR targets in patients with a mechanical aortic valve.

Methods

A 33-question web-based survey was sent to 75 cardiologists, cardiac surgeons and thrombosis specialists at centres in Canada and internationally (western Europe, South America, and the United States) who participated in previous anticoagulation trials led by investigators at McMaster University.

Results

Of the 55 respondents (73.3% response rate), 77.8% worked in academic teaching hospitals. Respondents had been in practice for a mean of 23.6 years; 40.9% followed AHA/ACC guidelines, 34.1% followed the ACCP guidelines and 22.7% followed the ESC guidelines. In patients with a mechanical aortic valve and no additional TE risk factors, 80% of respondents targeted an INR of 2.5 (range 2.0–3.0); among patients with additional TE risk factors, 48% targeted an INR of 2.5 (range 2.0–3.0) and 44% targeted an INR of 3.0 (range 2.5–3.5). With respect to guidelines: 57.1% of respondents agreed or strongly agreed that that the evidence for the guidelines was contemporary, 53.1% agreed or strongly agreed that the evidence was derived from patients with modern bi-leaflet mechanical valves, and 57.2% of respondents agreed or strongly agreed that the evidence was not of high quality. A majority of respondents (65.9%) reported that they would accept an increase in TE risk to reduce the risk of a major bleeding event; 86.4% are willing to randomize patients with a mechanical aortic valve to a target INR of 2.0 (range 1.5–2.5) if they had no risk factors for TE and 36.4% would randomize patients to a target INR of 2.0 with additional risk factors for TE.

Conclusions

Clinicians who participated in the survey followed different guidelines and employed different INR targets for patients with a mechanical aortic valve. A majority of respondents would be willing to randomize these patients to lower INR targets.

Antiplatelet therapy prescription patterns for acute coronary syndrome: a decade analysed

Background/Introduction

Guidelines recommend dual antiplatelet therapy (DAPT) with acetylsalicylic acid (ASA) and ticagrelor following acute coronary syndrome (ACS) regardless of management strategy. Despite this, prescription practices lag and appropriate DAPT is not utilized.

Purpose

We aimed to trend differences in P2Y12 inhibitor prescriptions between ACS patients managed with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). As well, we wanted to analyze the impact practice-changing trial publications, national guideline updates, and publicly funded drug coverage plans may have on prescription patterns.

Methods

From national databases, we obtained data for ACS patients in the province of Ontario, Canada between 2008 and 2018. Using an interrupted-time series with data aggregated monthly, we evaluated types of P2Y12 inhibitor prescribed at hospital discharge and changes to antiplatelet prescription patterns following publication of Ticagrelor versus Clopidogrel in Patients with Acute Coronary Syndrome (PLATO), Canadian Cardiovascular Society (CCS) antiplatelet therapy guidelines, and ticagrelor coverage by a publicly funded medication plan.

Results

We included 114,142 ACS patients; 49% underwent PCI and 8% required CABG. Between October 2008 and March 2018, the proportion of patients discharged on P2Y12 inhibitors increased from 73.4% to 87% (p&lt;0.0001) for PCI patients and 11.4% to 31.4% (p&lt;0.0001) for CABG patients. PLATO publication was associated with a 1.3% (p=0.002) monthly decline in clopidogrel prescriptions amongst PCI patients. The 2010 CCS antiplatelet therapy guidelines were associated with a 0.7% (p&lt;0.0001) monthly decline in clopidogrel prescriptions amongst PCI patients. The approval of ticagrelor by publicly funded medication plan was associated with an increase in ticagrelor prescriptions within the first month (24.5%; p&lt;0.0001) and a continued monthly increase (0.4%; p&lt;0.0001) in PCI patients. The approval was also associated with an increase in monthly ticagrelor prescriptions (0.2%; p&lt;0.0001) amongst CABG patients. The 2012 CCS antiplatelet therapy guidelines were associated with a decline in clopidogrel prescriptions within the first month (6.1%; p=0.003) and a monthly increase in ticagrelor prescriptions (0.3%; p=0.05) amongst PCI patients.

Conclusion

Drug coverage by a publicly funded medication plan and guideline updates had significant impact on P2Y12 inhibitor prescription practices. Despite improvements, P2Y12 inhibitor prescriptions for CABG patients are far behind PCI patients. Further research is necessary to address barriers to appropriate antiplatelet therapy in the ACS population.

Which long line do we use in very low birth weight neonates; umbilical venous catheter or peripherally inserted central catheter?

BACKGROUND

Umbilical venous catheters (UVC) and peripherally inserted central catheters (PICC) are commonly used in preterms. UVC is cheap, easy to insert but has shorter dwell time. UVC is replaced after 7 days due to the risk of complications. This is associated with increased cost, work, and risk of nosocomial infections. The aim of this study was to determine the antenatal and postnatal factors that predict the need for a central line for more than 7 days, thus helping select between UVC or PICC on day 1 of life in babies ≤1500 grams.

METHODS

We retrospectively collected antenatal and postnatal data of VLBW neonates over a period of 1 year who needed CL during their NICU stay. We then divided them into two cohorts. Group 1: CL ≤7 days. Group 2: CL > 7 days.

RESULTS

Sepsis and catheter complications were lower with use of a single CL or duration being ≤7 days. Birth weight, incomplete/no antenatal steroids, need for resuscitation, low Apgar's, RDS, hs-PDA, and initiation of feeds beyond 24 hours of birth were significant. The score was devised based on factors found significant that had an acceptable AUC of 0.767 on ROC analysis with a score of 1 or above having 74.8% sensitivity and 67.7% specificity for prediction of need for CL > 7 days.

CONCLUSIONS

Birth weight ≤1000 grams, incomplete steroids and need for resuscitation at birth were predictive of the need of CL beyond seven days, on day one of life.

Evolving Paradigms in the Management and Outcomes of Sarcomatoid Renal Cell Carcinoma in the Era of Immune Checkpoint Inhibitors

Renal cell carcinoma (RCC) is a common cancer that affects a significant number of patients every year around the world. The presence of sarcomatoid features in these tumors is considered a poor prognostic feature. Patients with RCC with sarcomatoid features had significantly worse outcomes when treated with sunitinib, the previous first-line standard of care therapy when compared to patients without such features. Multiple immune checkpoint inhibitors have recently been approved for the treatment of RCC. In this article, we review the literature available on the outcomes of patients with sarcomatoid RCC treated with immune checkpoint inhibitors.

Case Report: IgG multiple myeloma and chronic myeloid leukemia in a single patient

A 58-year-old man presented with recurrence of chronic myeloid leukemia (CML) after complete molecular remission in the setting of non-compliance with imatinib. He was restarted on imatinib and was also noted to have IgG kappa monoclonal gammopathy of undetermined significance (MGUS). The patient re-achieved molecular remission after resumption of imatinib, but his MGUS progressed to smoldering myeloma and he was eventually diagnosed with multiple myeloma (MM) and initiated on treatment for MM with thalidomide, bortezomib and dexamethasone. He has responded well to treatment of the myeloma and continues concurrent maintenance imatinib treatment for CML and is being evaluated for bone marrow transplant. The association of two concurrent hematological malignancies, CML and MM, is very rare and has been infrequently reported in literature. The pathophysiology of this has not yet been fully understood. This case report reviews the various theories to explain this and discusses the potential challenges of simultaneous treatment of MM and CML.

"I can guess the month … but beyond that, I can't tell" an exploratory qualitative study of health care provider perspectives on gestational age estimation in Rajasthan, India

BACKGROUND

Accurately estimating gestational age is essential to the provision of time-sensitive maternal and neonatal interventions, including lifesaving measures for imminent preterm birth and trimester-specific health messaging.

METHODS

We explored healthcare provider perspectives on gestational age estimation in the state of Rajasthan, India, including the methods they use (last menstrual period [LMP] dating, ultrasound, or fundal height measurement); barriers to making accurate estimates; how gestational age estimates are documented and used for clinical decision-making; and what could help improve the accuracy and use of these estimates. We interviewed 20 frontline healthcare providers and 10 key informants. Thematic network analysis guided our coding and synthesis of findings.

RESULTS

Health care providers reported that they determined gestational age using some combination of LMP, fundal height, and ultrasound. Their description of their practices showed a lack of standard protocol, varying levels of confidence in their capacity to make accurate estimates, and differing strategies for managing inconsistencies between estimates derived from different methods. Many frontline healthcare providers valued gestational age estimation more to help women prepare for childbirth than as a tool for clinical decision making. Feedback on accuracy was rare. The providers sampled could not offer ultrasound directly, and instead could only refer women to ultrasound at higher level facilities, and usually only in the second or third trimesters because of late antenatal care-seeking. Low recall among pregnant women limited the accuracy of LMP. Fundal height was heavily relied upon, despite its lack of precision.

CONCLUSION

The accuracy of gestational age estimates is influenced by factors at four levels: 1. health system (protocols to guide frontline workers, interventions that make use of gestational age, work environment, and equipment); 2. healthcare provider (technical understanding of and capacity to apply the gestational age estimation methods, communication and rapport with clients, and value assessment of gestational age); 3. client (time of first antenatal care, migration status, language, education, cognitive approach to recalling dates, and experience with biomedical services); and, 4. the inherent limitations and ease of application of the methods themselves.

Assessing inequities in community health worker’s interaction and its impact in Uttar Pradesh, India

Given the high Neo-natal mortality in the state of Uttar Pradesh, India, an emphasis has been given to community health workers (CHW). CHW provides behavior push to pregnant women for utilizing health services, through the strategies of household contact and messaging. However, the disparity in health outcomes and interaction of CHW is profoundly affected by socio-economic determinants; still, the evidence is limited. This study aims to explore socio-economic inequities in quantity and quality of contacts by the CHW and its differential effect on health service utilization.

Multistage sampling design identified live births in the last 12 months across the 25 highest-risk districts of Uttar Pradesh(n = 3703). Regression models described the relation between household demographics and CHW contact & specific messaging and interactions of demographics and CHW contact & messaging in predicting health service utilization ( &gt; = 4 antenatal care (ANC) visits, Institutional delivery and 100 iron folic acid (IFA) consumption).

No differential likelihood in contact of CHW and specific messaging is found. Further, association of CHW contacts and specific messaging with health outcomes were significantly affected by socio-economic determinants.2 or more contacts along with specific messaging increased the odds of 4+ ANC to a higher degree among illiterate women compared to literate women(AOR:3.39, 95% CI:2.28-5.04 vs AOR:1.44, 95% CI:1.09-1.92). Similarly, the odds of facility delivery increased to a higher degree among lower wealth women compared to higher wealth women (AOR:3.41, 95% CI:2.47-4.71 vs. AOR:1.53, 95% CI: 1.09-2.15).

Specific messaging, along with CHW contacts, have a higher magnitude of effects on the marginalized population. This study provides evidence for adjusting implementation strategies based on socio-economic determinants to achieve equitable health service utilization. However, further research on training of CHW on heterogeneous interaction is recommended

Key messages

There exists differential effects of quantity and quality of contact by community health workers on health service utilization across the different socio-economic strata. Implementation agencies in the LMIC can reduce health inequity by shifting from coverage-oriented target approach towards more prioritized and focused interaction across socio-economic groups.

Assessing Contact, Coverage, and Quality of continuum of care in Uttar Pradesh, India

Background

Given the high neonatal mortality in LMIC, strategies suggest a continuum of care (COC) as an effective framework to ensure timely and appropriate service provision throughout the MNCH continuum. However, the measurement approaches traditionally focus on assessing continuum of care from the lenses of time-based coverage and missing out on the quality of coverage and service delivery. This paper aims to assess the continuum of care based on these three parameters and the factors affecting its achievement.

Methods

Multistage sampling design identified live births and stillbirths in the last calendar year (March 2018-February 2019) across the 50 districts of Uttar Pradesh(n = 16646).COC was assessed on three measurements 1) Contact: Any contact with the health system across the continuum, 2)Coverage: Adequate contacts of the health system through outreach services and clinical care, and 3)Quality: receiving adequate services along with these contacts. Further, a multilevel regression model was used to estimate the factors associated with the continuum of care.

Results

64% (60.04-67.65) of the women and child received health system contact across the continuum while only 2.1% (1.57-2.78) and 2.8% (2.33-3.44) women and children achieved coverage and quality based COC, respectively. Achievement of COC coverage and COC quality is highly affected by the service delivery platform, with women at outreach platform being more likely to achieve adequate coverage while women at facilities are more likely to achieve quality services across ANC, delivery, and PNC.

Conclusions

Achievement of both coverage and quality based COC remains low in Uttar Pradesh, India. Even those who achieve contact(s) failed to receive quality services along with these contacts with health systems. Efforts should be focused on building quality service at the outreach and non-outreach platforms across the continuum of care for reducing the risk of neonatal mortality.

Key messages

Owing to the lack of an integrated approach for service delivery across outreach, clinical care and community care, continuum of care remains broken for most of the mothers and children. For targeting coverage and quality of COC, focus should be on improving the quality of service provision across the outreach platforms which are already in reach of the women.

Incidental early diagnosis of biphasic pulmonary blastoma in a patient with history of stage IV lung adenocarcinoma

Biphasic pulmonary blastoma is a rare but lethal type of lung malignancy with characteristic histology of both epithelial and mesenchymal components. Previously reported cases have been limited to presentation at advanced stages, suggesting that the clinical course of the disease is usually aggressive. Here, we report a case of incidental diagnosis of biphasic pulmonary blastoma by imaging surveillance in a patient previously treated for adenocarcinoma of the lung. The patient was diagnosed with stage 1 disease and underwent successful resection. Next‐generation sequencing (NGS) revealed a high mutation burden, a finding not previously reported in a patient with biphasic pulmonary blastoma.
