Background
The Heart Rhythm Society (HRS) and European Heart Rhythm Association (EHRA) consensus states complete extraction is recommended for all patients with definite cardiac implantable electronic device (CIED) infection. Although complete removal of hardware is the best way to manage infections, lead extraction is a complex procedure with significant risk. As age and complexity of patients increase so too does extraction risk. In very high risk cases conservative management is cited, though little is known on outcomes.
Purpose
We are a high volume tertiary centre which serves a population of 2 million. 2 experienced operators perform 65 extraction procedures per year for the past 10 years. We report our experience of device reburial as initial management of CIED pre-erosion and erosion in cases deemed too high risk for extraction.
Method
We retrospectively reviewed all reburial procedures undertaken over 9 years. Patient and lead factors influencing decisions were assessed. Information on number of leads, dwell time, prior procedure, infective status and comorbidity was collated. The outcomes included morbidity, defined by repeat procedure (revision and/or extraction) and mortality.
Results
86 patients underwent 96 procedures from March 2013 until August 2020. All patients undergoing device reburial were included. 55.8% of patients were male, mean age was 73. 21 patients died, 7 of these deaths occurred within 12 months of the index reburial procedure. The mean follow up period was 39 months (range 5–90). 65.1% of patients had a procedure (de novo implant, upgrade or replacement) within 12 months prior to revision.
We reviewed patients in 2 subgroups based on revision indication – erosion and pre-erosion. Erosion was defined as externalised lead/device. Pre-erosion was defined as superficial device with skin tethering but no exposure. The former is a definite indication for lead extraction, the latter a relative indication. All in the pre-erosion group were systemically well with no infection evident. One patient with erosion had a positive blood culture.
The mean age in the erosion group was 85 years with a Clinical Frailty Score (CFS) 4.98 and lead dwell time 17.87 years compared to age 68 years, CFS 3.98 and dwell time 8.14 years in the pre-erosion group. Patients in this cohort with an eroded device were deemed too high risk to undergo transvenous lead extraction.
A higher proportion of patients presenting with erosion died within 12 months of the index reburial procedure (16.67% vs 4.84%). 21% with an eroded device and 11% with a pre-eroding device undergoing reburial as first line management required future extraction.
Conclusion
Our 9 year data suggests less invasive intervention is a valid option in high risk groups such as older age, frailty, long lead dwell time, with an acceptable incidence of reintervention and/or extraction. This data can help guide informed consent in the future.

Background
Heart failure (HF) is associated with significant morbidity and mortality. (1) Cardiac Implantable Electronic Devices (CIED) generated Heart Failure Risk Score (HFRS) alerts may guide management in this complex cohort and help direct resources to appropriate patients. (2)
Aim
To develop and evaluate an integrated, multidisciplinary approach to HF management for patients with CIED by sharing HFRS alerts directly with the HF teams.
Methods
We undertook a prospective, single centre cohort study of patients who generated high risk HFRS alerts. These alerts were shared with community HF teams responsible for routine care of patient, prompting patient contact and appropriate intervention by the team. Impact of the pathway was evaluated by review of outcomes including hospitalisation and clinical intervention within 4- 6 weeks of the alert and mortality during the follow up period. Ongoing education was provided to help teams deal with alerts. A validated user questionnaire was completed by the stake holders to obtain user feedback.
Results
365 "High risk" alerts were noted in 188 patients in a 2 year period (November 2018 - November 2020). The mean number of alerts per patients was 1.9 and 44 (23%) of patients had >3 "high risk" alerts in the follow up period. Having three or more alerts significantly increased the risk of hospitalisation for heart failure (HR 2.5, CI 1.1–5.6 p = 0.03) but not mortality (HR 2.1 CI 0.6-7.2 p = 0.23). Overall 75 (39%) of patients were hospitalised in the 4-6 week period of the alert – 53 (28%) of these were unplanned of which 24(13%) were for decompensated HF. A further 24(13%) had planned admissions for care to improve therapy (AV node ablation, device and lead replacement) and reduce morbidity (LA appendage occlude, IV Iron therapy). 33(18%) of patients died in the follow up period. 15(8%) received therapy from the device. 18(10%) of patient underwent deactivation of ICD therapy.
Contact was established in 176 (94%) of patients, and alerts actioned appropriately. 55 patients reported being asymptomatic, and in 45 the trends were improving so no further clinical action was taken. 76 patients had an onward referral made for further management including; 32 to a Cardiologist, 20 to primary care, 13 referrals to community HF teams and 11 referrals to palliative care. 23 patients had medications changes instituted. The feedback on the pathway was positive.
Conclusions
An integrated approach to HF for patients with CIEDs in situ can facilitate timely risk stratification and intervention in this cohort of patients and potentially reduce unplanned health care utilisation. Intervention in these patients is not limited to HF alone and provides the opportunity for holistic management of this complex cohort Abstract Figure.

Int J Emerg Med 2021; 14:32. [PMID: 34011284 PMCID: PMC8132346 DOI: 10.1186/s12245-021-00347-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 04/12/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The chief or presenting complaint is the reason for seeking health care, often in the patient's own words. In limited resource settings, a diagnosis-based approach to quantifying burden of disease is not possible, partly due to limited availability of an established lexicon or coding system. Our group worked with colleagues from the African Federation of Emergency Medicine building on the existing literature to create a pilot symptom list representing an attempt to standardize undifferentiated chief complaints in emergency and acute care settings. An ideal list for any setting is one that strikes a balance between ease of use and length, while covering the vast majority of diseases with enough detail to permit epidemiologic surveillance and make informed decisions about resource needs. METHODS This study was incorporated as a part of a larger prospective observational study on human immunodeficiency virus testing in Emergency Departments in South Africa. The pilot symptom list was used for chief complaint coding in three Emergency Departments. Data was collected on 3357 patients using paper case report forms. Chief complaint terms were reviewed by two study team members to determine the frequency of concordance between the coded chief complaint term and the selected symptom(s) from the pilot symptom list. RESULTS Overall, 3537 patients' chief complaints were reviewed, of which 640 were identified as 'potential mismatches.' When considering the 191 confirmed mismatches (29.8%), the Delphi process identified 6 (3.1%) false mismatches and 185 (96.9%) true mismatches. Significant chief-complaint clustering was identified with 9 sets of complaints frequently selected together for the same patient. "Pain" was used 2076 times for 58.7% of all patients. A combination of user feedback and expert-panel modified Delphi analysis of mismatched complaints and clustered complaints resulted in several substantial changes to the pilot symptom list. CONCLUSIONS This study presented a systematic methodology for calibrating a chief complaint list for the local context. Our revised list removed/reworded symptoms that frequently clustered together or were misinterpreted by health professionals. Recommendations for additions, modifications, and/or deletions from the pilot chief complaint list we believe will improve the functionality of the list in low resource environments.

Abstract
It is shown how serial block-face electron microscopy (SBEM) of insulin-secreting β-cells in wild-type mouse pancreatic islets of Langerhans can be used to determine maturation times of secretory granules. Although SBEM captures the β-cell structure at a snapshot in time, the observed ultrastructure can be considered representative of a dynamic equilibrium state of the cells since the pancreatic islets are maintained in culture in approximate homeostasis. It was found that 7.2 ± 1.2% (±st. dev.) of the β-cell volume is composed of secretory granule dense-cores exhibiting angular shapes surrounded by wide (typically ≳100 nm) electron-lucent halos. These organelles are identified as mature granules that store insulin for regulated release through the plasma membrane, with a release time of 96 ± 12 h, as previously obtained from pulsed 35S-radiolabeling of cysteine and methionine. Analysis of β-cell 3D volumes reveals a subpopulation of secretory organelles without electron-lucent halos, identified as immature secretory granules. Another subpopulation of secretory granules is found with thin (typically ≲30 nm) electron-lucent halos, which are attributed to immature granules that are transforming from proinsulin to insulin by action of prohormone convertases. From the volume ratio of proinsulin in the immature granules to insulin in the mature granules, we estimate that the newly formed immature granules remain in morphologically-defined immature states for an average time of 135 ± 14 min, and the immature transforming granules for an average time of 130 ± 17 min.

Abstract
Commonly used lactose assays [enzymatic spectrophotometric absorbance (EZA) and HPLC] for dairy ingredients are relatively expensive and time consuming. A blood glucose meter (BGM)-based method has successfully been documented as a rapid lactose assay in milk. However, the BGM-based method has not been evaluated in dairy ingredients. The objective of this study was to evaluate the BGM-based lactose analysis method in whey-derived (WD) and skim milk-derived (SMD) ingredients. The study was carried out in 4 phases. In phase 1, the effect of pH and lactose concentrations on the BGM reading was investigated using a factorial design with 2 factors: pH (6.02-7.50) and lactose (0.2 or 0.4%). We found that BGM readings were significantly affected by lower pH values at both lactose levels. In phase 2, the effect of total solids and ingredient type was investigated using a factorial design with 2 factors: ingredient type (WD or SMD) and total solids (0-8%). It was observed that the BGM reading was significantly affected by ingredient type and total solids. Phase 3 involved developing a linear relationship between the BGM reading and the EZA reference method to ascertain the accuracy of the proposed BGM method. Different ingredient types (WD or SMD) and non-lactose solids (0.5-27%) model ingredient dilutions prepared over a range of lactose contents (0.08-0.62%) were measured using the BGM and EZA methods. The average absolute percentage bias difference between the BGM method and EZA reference method results for these model dilutions was found to be between 2.2 and 7.3%. In phase 4, 15 samples procured from commercial sources ranging from 0.01 to 81.9% lactose were evaluated using the BGM method and EZA reference method. The average absolute percentage bias difference for lactose results between the 2 methods ranged from 3.6 to 5.0% and 5.3 to 9.7% for well-performing and poorly performing meters, respectively. Overall, the BGM method is a promising tool for rapid and low-cost analysis of lactose in both high-lactose and low-lactose dairy ingredients.

Abstract
Background:Periodontitis (PD) has long been linked with Rheumatoid arthritis (RA) [1]. Epigenetic modifications are being recently explored to explain such associations, DNA methylation being one such important mechanism.Objectives:To study the effect chronic generalized periodontitis on systemic methylation of TLR4 genes in comparison to only RA and RA with PD patients.Methods:Twenty-three RA patients, among which 11 patients had chronic generalized PD, 20 patients with only PD and 15 healthy individuals recruited. DNA was isolated from PBMCs of the participants blood, then were first bisulphite converted and then methylation specific PCR were performed using primers for methylated and um-methylated promoters of TLR4. The DNA amplifications were checked in horizontal gel electrophoresis. The methylation signatures were verified by DNA sequencing (Sanger) of the amplified products.Results:The anti-CCP, DAS-CRP and HAQ DI were higher in patients with both RA and PD (220±40, 5.7±0.2, 1.5±0.1 respectively, p<0.05). Control samples had shown amplification bands for methylated primers of TLR4 but not for un-methylated primers of TLR4. However, only RA, only PD and RA with PD samples, had shown amplification for un-methylated primers and not for methylated primers. These results together with DNA sequencing indicated that 4 CpG sites in the promoter ofTLR4 genes were hypo-methylated in the PBMCs of patients whereas those remain methylated in healthy individuals.Conclusion:The observations indicated that though PD is a localised disease of the gingiva there is a systemic involvement of TLR mediated pathways in them which is similar to those in RA. However, further validation in larger cohort and down-stream signalling molecules needs to be studied.References:[1]Ceccarelli F, Saccucci M, Di Carlo G, Lucchetti R, Pilloni A, Pranno N, Luzzi V, Valesini G, Polimeni A.

Foldscope as a primary diagnostic tool for oral and urinary tract infections and its effectiveness in oral health education. J Microsc 2020; 279:39-51. [PMID: 32286690 DOI: 10.1111/jmi.12896] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2020] [Revised: 03/28/2020] [Accepted: 04/08/2020] [Indexed: 11/28/2022]
Abstract
Due to its speed, accuracy and cost-effectiveness, microscopy has become an integral part of clinical examination for disease diagnosis. However, modern microscopes are very costly and require skilled personnel for their operation and maintenance, and specimen processing and analysis is labour-intensive. Further, lack of such expensive diagnostic tools in remote areas is a serious concern. Affordable point-of-care diagnostic tools are the most useful for timely disease diagnosis and management. The Foldscope is an affordable origami-based microscopy device composed of a series of paper clippings, which, upon assembly, can hold a specimen slide for observation, and this specimen can be viewed via a mobile phone camera attached to it. The present study evaluated the use of the Foldscope in the clinical diagnosis of oral and urinary tract infections and evaluated its efficacy as a motivational tool for improving oral health among school children in India. We qualitatively compared the Foldscope to a clinical microscope by examining five different types of clinical samples. Of the different types of clinical samples, the Foldscope was effective in detecting infection in dental plaque samples and urine samples. Thus, we further analysed 31 dental plaque samples of patients aged 3-13 years and 25 urine samples of patients aged 11-62 years. We also evaluated the use of the Foldscope as an educational tool for motivating oral hygiene among 80 school children aged 12 years and found that students in the Foldscope intervention group had better measures of oral hygiene than did students in the nonintervention group. In summary, our study indicated that the Foldscope is useful in detecting urinary tract infections and kidney stones in urine samples and is a useful motivational tool for oral health education among school-aged children. Furthermore, it may also be useful in oral health monitoring in resource poor settings. LAY DESCRIPTION: Poor and remote population often suffers due to lack of capacity to buy products or avail services which are expensive. In such a society people are not able to afford even the basic detection of diseases. Foldscope may come to rescue here! Foldscope is a paper-based, use-and-throw, affordable microscope. This study explores the use of Foldscope in clinics and diseases diagnosis using patient samples. Preliminary detection of disease associated symptoms in dental and urinary infections and digital record keeping via storage in mobile phone memory and hospital OPD records for monitoring patient's health are some of the advantages of Foldscope for clinical use in resource poor settings. It identifies that Foldscope not only can be used by students or teachers for educational purposes but it can also pave a path for promotion of dental hygiene among young children. The study also suggests that further improvement in design or resolution of Foldscope will broaden the scope of its application, in future.

Abstract
Single Nucleotide Polymorphism (SNP) is one of the important molecular markers widely used in animal breeding program for improvement of any desirable genetic traits. Considering this, the present study was carried out to identify, annotate and analyze the SNPs related to four important traits of buffalo viz. milk volume, age at first calving, post-partum cyclicity and feed conversion efficiency. We identified 246,495, 168,202, 74,136 and 194,747 genome-wide SNPs related to mentioned traits, respectively using ddRAD sequencing technique based on 85 samples of Murrah Buffaloes. Distribution of these SNPs were highest (61.69%) and lowest (1.78%) in intron and exon regions, respectively. Under coding regions, the SNPs for the four traits were further classified as synonymous (4697) and non-synonymous (3827). Moreover, Gene Ontology (GO) terms of identified genes assigned to various traits. These characterized SNPs will enhance the knowledge of cellular mechanism for enhancing productivity of water buffalo through molecular breeding.
