Quantitative analysis of tiliroside and other flavonoid glycosides in Hippophae salicifolia D. Don leaves by HPLC-PDA

A new HPLC-PDA method was developed and validated for simultaneous determination of five phenolic compounds (trans-and cis- isomers of tiliroside, quercetin-3-O-β-D-glucoside, ellagic acid, kaempferol-3-O-β-D-glucoside and isorhamnetin-3-O-glucoside) in the leaves of Hippophae salicifolia D. Don. Of the five compounds, three (tiliroside, quercetin-3-O-β-D-glucoside and ellagic acid) were isolated and characterised by spectroscopy techniques. The developed HPLC method provided a selective, sensitive and rapid analysis with good linearity (r2> 0.999), accuracy and precision. Also, the leaves of H. salicifolia were extracted by three different extraction techniques viz. reflux, microwave and ultrasound. Methanolic extracts prepared by reflux method showed the highest content of all the five compounds.

'PartBreCon' study. A UK multicentre retrospective cohort study to assess outcomes following PARTial BREast reCONstruction with chest wall perforator flaps

BACKGROUND

Partial breast reconstruction with a pedicled chest wall perforator flap (CWPF) enables breast conservation in a higher tumour: breast volume ratio scenario. Since there is limited evidence, this retrospective cohort study aimed to ascertain immediate (30-days) and medium-term (follow-up duration) surgical outcomes.

METHODS

STROBE-compliant protocol ascertained CWPF outcomes between March 2011-March 2021. UK centres known to perform CWPF were invited to participate if they performed at least 10 cases. Data were retrospectively collected, including patient demographics, tumour and treatment characteristics, and surgical and oncological outcomes. Statistical analysis (R™) included multivariable logistic regression and sensitivity analysis.

RESULTS

Across 15 centres, 507 patients with median age (54 years, IQR; 48-62), body mass index (25.4 kg/m2, IQR; 22.5-29), tumour size (26 mm, IQR; 18-35), and specimen weight (62 g, IQR; 40-92) had following flap types: LiCAP (54.1%, n = 273), MiCAP/AiCAP (19.6%, n = 99), LiCAP + LTAP (19.8%, n = 100) and TDAP (2.2%, n = 11). 30-days complication rates were in 12%: haematoma (4.3%, n = 22), wound infection (4.3%, n = 22), delayed wound healing (2.8%, n = 14) and flap loss (0.6%, n = 3; 1 full) leading to readmissions (2.6%, n = 13) and re-operations (2.6%, n = 13). Positive margins (n = 88, 17.7%) led to 15.9% (n = 79) re-excisions, including 7.5% (n = 37) at the planned 2nd of 2-stage surgery and 1.8% (n = 9) mastectomy. At median 23 months (IQR; 11-39) follow-up, there were 1.2% (n = 6) symmetrisations; recurrences: local (1%), regional/nodal (0.6%) and distant (3.2%).

CONCLUSIONS

This large multicentre cohort study demonstrates acceptable complication and margin re-excision rates. CWPF extends the range of breast conservation techniques. Further studies are required for long-term oncological outcomes.

Validity of CHA2DS2-VASc score in patients with malignancies

Introduction

Anticoagulation for patients with atrial fibrillation/flutter (AF) after risk stratification based on CHA2DS2-VASc score (congestive heart failure, hypertension, age group, Diabetes Mellitus, prior stroke, transient ischemic attack or thromboembolism, prior heart attack, peripheral artery disease or aortic plaque and patient's gender) has been the gold standard practice to prevent cerebrovascular accidents (CVA).

Purpose

Since patients with malignancies are at increased risk of thrombophilia, we tried to study if cancer patients with atrial fibrillation are at increased risk for CVA beyond what should be expected based on their comorbidities.

Methods

We used the Nationwide Readmissions Database (NRD) database for the years 2016–2019. First, we extracted all cases with a diagnosis of atrial fibrillation/flutter. Exclusion criteria included patients younger than 18-year-old. We studied the comorbidities and calculated CHA2DS2-VASc score. Then, we compared the risk for admission with an acute CVA in patients with and without any diagnosis of malignancies (solid cancer, leukemia, lymphoma or metastatic disease). Patients with carcinoma in situ were considered non-cancer patients. Corrected logistic regression and Chi-square tests using survey procedures in SAS 8.1 were applied to accommodate for complex sampling (Rao-Scott design).

Results

We identified 1,748,619 weighted admissions with AF equally distributed across the years. 5% were patients with malignancies. The mean age was 74-year-old for cancer patients and 71-year-old for non-cancer patients with quite equal gender distribution (43–49% were female). Patients with a diagnosis of cancer has high inpatient mortality (13%). Every additional point in CHA2DS2-VASc score was associated with increased odds of admission with CVA. Having a diagnosis of cancer was not associated with increased odds of admission with CVA (odd ratio for 95% confidence interval 1.0 [0.95–1.1]). Patients with history of VTE (assuming they are on anticoagulation) or who are on chronic anticoagulation have lower risk of admission with acute CVA if they have AF.

Conclusions

Although malignancies is associated with hypercoagulable status including higher risk for stroke, deep venous thrombosis and pulmonary embolism, our cross-sectional study indicates that CHA2DS2-VASc score is still a reliable tool for risk stratification in patients with atrial fibrillation. More longitudinal studies are needed.

Ethnopharmacology and Phytochemistry of Selected Species of Boerhavia Occurring in India: A Review

Background:

The plant species belonging to the genus Boerhavia (Nyctaginaceae) have been used extensively in ethnomedicine and Ayurveda in India. Raktapunarnava and Shweta punarnava are two of the species which find mention in various Ayurvedic formulations. Other species of Boerhavia, though not found in Indian system of medicine, do hold importance in ethnomedicine systems in India and other countries.

Objective:

Boerhavia being a polymorphic genus, has been treated as a single genus encompassing species belonging to a morphologically related genus Commicarpus also. Owing to this taxonomic quandary with regard to merger or separation of the two genera by different workers, there are different reports of the number of species belonging to the genus. This has further resulted in flawed reporting of ethnomedicinal as well as ethnopharmacological studies. The present review focuses on resolving any confusion in taxonomic treatment, to highlight the ethnomedicinal uses supported by ethnopharmcological data and the phytochemistry of Boerhavia and Commicarpus species found in India.

Conclusion:

In India four species of Boerhavia and two species belong to Commicarpus have been reported to occur. The literature survey revealed that except B. diffusa, no other species of Boerhavia has been explored in detail. This presents an opportunity to undertake research on Boerhavia species and find new phytochemicals with promising therapeutic effects.

Hippophae salicifolia D. Don, a Fascinating Medicinal Plant: An Update on its Traditional Medicinal Uses, Ethnopharmacology and Phytochemistr

Abstract:

Hippophae salicifolia, belonging to family Elaegnaceae, is a thorny shrub, and shows actinorhizal habit. The species prefers a habitat of temperate regions in Europe and Asia. In India, it is distributed in the Himalayan region of Uttarakhand, Himachal Pradesh, Jammu and Kashmir, and the North-Eastern parts. The oil, fruits, leaves, and bark of Hippophae species have a pronounced use in ethnomedicines, nutritional food, cosmetics, nitrogen-fixing in soil, water conservation and as fuel source. The aim of this review is to provide updated, comprehensive, and classified information on the traditional uses, phytochemistry, pharmacological and toxicological research carried out on H. salicifolia. This will help researchers to explore its therapeutic potential and examine future research possibilities. The chemical composition of this shrub comprises minerals, vitamins, flavonoids, flavonoid glycosides, polyunsaturated fatty acids, sugars, carotenoids, and nucleobases. Pharmacological studies demonstrated that the extracts prepared from leaves, barks, and berries along with fixed oil of this species are useful as anti-oxidant, anti-inflammatory, anti-cancer, anti-diabetic, anti-depressant, anti-microbial, adaptogenic, and wound healing. The results of toxicity study of H. salicifolia extracts did not show any significant acute toxicity in experimental animals. Abundance of phenolic compounds, minerals, and fatty acids within the different parts of this plant prompted researchers to isolate and characterize the phytoconstituents which are responsible for its therapeutic uses.

INFLUENCE OF THE DURATION OF DIABETES AND VIBRATION PERCEPTION THRESHOLD ON THE SEVERITY OF ERECTILE DYSFUNCTION IN PATIENTS WITH TYPE 2 DIABETES MELLITUS

BACKGROUND

Erectile dysfunction(ED) in men is a frequent under-reported complication of diabetes mellitus, which is becoming significant health problem worldwide.

AIMS

The study aims to determine the prevalence and risk factors for development of ED in North Indian patients with type 2 diabetes mellitus.

METHODS

We used international index of erectile function (IIEF-5) for the assessment of ED in 796 patients with type 2 diabetes mellitus. We recorded the age, duration of diabetes, glycemic status, body mass index, diabetes medications, microvascular and macrovascular complications.

RESULTS

The mean age of patients in the study was 49.38 ± 9.52 years. The prevalence of ED in patients with type 2 diabetes mellitus was 79.4%. Logistic regression analysis revealed that age, body mass index, glycemic control, insulin therapy, retinopathy and nephropathy was not significantly associated with erectile dysfunction in patients with type 2 diabetes mellitus. Duration of diabetes (OR = 1.054, 95% CI 1.007 to 1.102, P=0.023) and vibration perception threshold (OR = 1.071, 95% CI 1.042 to 1.102, P=0.000) were identified as key risk factors for development of ED.

CONCLUSION

Duration of diabetes and peripheral neuropathy emerged as significant risk factors for development of severe erectile dysfunction.

An evaluation of remineralised MIH using CPP-ACP and fluoride varnish: An in-situ and in-vitro study

BACKGROUND

Molar incisor hypomineralization (MIH) affected teeth have enamel with altered mineral content like decreased calcium and phosphorus and increased carbon content leading to porous enamel and subsequent post-eruptive breakdown.

AIM

An in situ study was conducted to evaluate and compare the effects of a Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP)-based cream and fluoride varnish on the remineralization of MIH affected teeth.

METHODS

Enamel slabs were prepared from MIH affected teeth that had been extracted for various reasons and inserted in appliances of 30 participants who were undergoing interceptive orthodontic therapy. They were randomly divided into two groups using block randomization technique: Group A-daily single application of CPP-ACP cream (n = 15); Group B-professional application of fluoride varnishes every 3 months (n = 15). After 6 months of regular wear of the appliance, the enamel slabs were placed under Field Emission Scanning Microscope (FESEM) and Energy-Dispersive Spectroscopy (EDS) for evaluation of ultra structure and mineral content, respectively.

RESULTS

A significant increase in calcium and phosphorus content, and a decrease in carbon content was observed within the 6 months period, suggesting remineralization in both the groups. On comparing the Ca:P and Ca:C ratios, a significant increase in the Ca:C ratio was evident in the two groups. No significant difference was seen in the Ca:P ratio in the CPP-ACP group at six months. The inter-group comparison did not reveal any significant difference between the two groups either at baseline or at 6 months post-intervention.

CONCLUSION

Remineralization can be achieved in MIH affected teeth with the use of remineralizing agents.

Full coverage crowns for rehabilitation of MIH affected molars: 24 month randomized clinical trial

BACKGROUND

Teeth affected with severe molar incisor hypomineralization (MIH) require extensive restorations, which do not last for a long time and often require treatment in the form of onlays or full coverage restorations.

AIM

To evaluate and compare the clinical performance of zirconia, lithium disilicate, and cast metal crowns as full-coverage restorations on MIH-affected first permanent molars (FPMs).

METHODS

60 MIH affected FPMs requiring full-coverage crowns were identified in children aged 8-15 years and were randomly allocated to the three treatment groups according to the type of full coverage restoration received using block randomization technique. After an adequate removal of the MIH defect and restoration with composite resin, the tooth preparation was done followed by fabrication of crown and its cementation using resin cement. The intergroup comparison was done on the basis of USPHS criteria, gingival, plaque scores, patient and parents acceptance through a visual analog scale to decipher their clinical performance at 6, 12, 24 months.

RESULTS

After 24 months, the crowns showed similar clinical success in terms of the criterias used to compare their clinical performance. The retention, marginal adaptation, relief from hypersensitivity, proximal contact, gingival health with no statistically significant difference among the three groups.

CONCLUSION

Based on the observations, Lithium disilicate, Zirconia and full cast metal crowns showed similar clinical success in rehabilitation of First permanent molars with severe MIH over 24 months of evaluation. The clinical success is not influenced by the material of the restoration. However, prospective studies with a longer follow-up are required to reach a more definitive conclusion.

Label-free quantitative proteomics reveals molecular correlates of altered biomechanical properties in molar incisor hypomineralization (MIH): an in vitro study

PURPOSE

Molar-incisor hypomineralization (MIH) is a qualitative developmental defect of enamel that affects first permanent molars with or without affecting permanent incisors. We aimed to carry out a quantitative proteomics-based study to compare and evaluate proteins in sound and MIH-affected enamel.

MATERIALS AND METHODS

Ten blocks each of the MIH-affected enamel and sound enamel were processed and prepared for LC-MS/MS analysis. Label-free quantitation was carried out to evaluate the differentially expressed proteins in the two groups of samples.

RESULTS

A significant increase in the number of proteins in MIH-affected enamel (50.3 ± 29.6) was observed compared to the sound enamel (21.4 ± 3.2). While proteins like collagens, α1-anti-trypsin, kallikrein-4 (KLK4), matrix metalloprotease-20 (MMP-20), alpha-2-macroglobulin, and alpha-2-HS-glycoprotein were upregulated in sound enamel, there was over-expression of albumin, calcium-binding proteins, anti-thrombin III, and dentin sialophosphoprotein (DSPP), along with proteins implicated in stress response and inflammatory processes in MIH.

CONCLUSION

We propose that altered biomechanical properties of the enamel in MIH samples arise due to (i) down-regulation of proteins contributing to collagen biosynthesis and fibril formation; (ii) an overall imbalance in required levels of proteases (KLK4 and MMP-20) and anti-proteases (anti-thrombin-III which inhibits KLK-4), essential for optimal mineralization; (iii) very low levels of alpha-2-macroglobulin with important consequences in enamel mineralization and amelogenesis; and (iv) increased albumin in MIH, preventing proper growth of hydroxyapatite crystals. Increased inflammatory component was also seen in MIH; however, whether inflammation is a cause or consequence of the poor mineralization process needs to be assessed.

Salivary parameters and their correlation with neutrophil counts in children with acute lymphoblastic leukemia

BACKGROUND

Chemotherapy for Acute Lymphoblastic Leukemia (ALL) is known to render children immuno-deficient. A concomitant suppression of local defence mechanisms, such as saliva may further aggravate the adverse consequences of chemotherapy. The present study was conducted to evaluate alterations in salivary flow rate, pH and buffering capacity and to correlate these parameters with Absolute Neutrophil Counts (ANC).

METHODS

A cohort of 43 patients, aged 3-12 years were evaluated for the aforementioned parameters at baseline, post-induction and post-consolidation phases. Salivary collection was done and ANC was measured from routine haematological reports.

RESULTS

A decrease in the salivary parameters was observed at the end of Induction phase as compared to baseline, with a statistically significant decrease in unstimulated salivary flow rates (p < 0.01). Statistically significant positive correlations were found between ANC and salivary flow rate (p = 0.005), pH (p < 0.00) and buffering capacity (p < 0.00). On testing the significance of these correlations, all the values for these parameters were found to be statistically significant.

CONCLUSION

Salivary parameters showed derangements over the phases of chemotherapy, with maximum decrease at the end of induction phase. The positive correlations of salivary parameters with ANC of the subjects may be considered indicative of a concomitant immunological compromise in these children.

1191 The Use of CT Urography to Diagnose Upper Tract Urothelial Carcinomas (UTUC); Managing Surgical Resources During The COVID-19 Pandemic

Introduction

Upper tract urothelial carcinomas (UTUC) account for 5-10% of urothelial malignancies. Rapid diagnosis is essential as 60% are invasive at diagnosis and confer poor prognoses. European Association of Urology (EAU) guidelines recommend CT urography (CTU) for initial diagnosis and staging of UTUCs. Diagnostic ureteroscopy (URS) is used second line where diagnosis is unclear. The COVID-19 pandemic has limited theatre access and may delay diagnosis of suspected UTUC. Our aim was to evaluate specific CTU findings in predicting UTUC to aid prompt diagnosis and risk stratification in a tertiary centre.

Method

A retrospective analysis was performed on 122 patients who underwent CTU with diagnostic URS over two years from 2018-2019 for possible UTUC. Data including demographics, imaging and histology were collected from our electronic database.

Results

57 patients had confirmed UTUC, all had CT changes. CTU had an overall positive predictive value (PPV) of 45%. CT findings were divided into: hydronephrosis; filling defect/lesion; urothelial thickening; normal; or other. The PPV was highest for filling defects/lesions at 60%, hydronephrosis was 38%, urothelial thickening was 30%, and other was 33%. Of those with high-grade histology, 61% had evidence of filling defects/lesions and 24% had hydronephrosis.

Conclusions

A specific CTU finding of filling defect/lesion in combination with cytology can aid diagnosis and risk stratification of UTUC. This may enable us to reduce use of diagnostic URS, as well as associated risks of intravesical seeding, necessary in the COVID-19 pandemic. With other CTU findings of hydronephrosis or urothelial thickening, a diagnostic URS may be required.

1054 A Simple Intervention to Minimise the Incidence of The Forgotten Ureteric Stent: Updating the Surgical Discharge Summary

Introduction

Ureteric stents are routinely used in ureteric obstruction, however, have considerable morbidity with major complications, such as encrustation, obstruction, urosepsis, and renal failure if left in situ for longer than six months. Despite an electronic stent register, there are still multiple emergency admissions of complications from forgotten stents, as well as those presenting with significant stent symptoms. Often stents are inserted as an emergency procedure with minimal information given on their discharge summary. A discharge template was therefore introduced that could also serve as a patient information leaflet to help minimise the incidence of forgotten stents.

Method

A discharge template was designed based off the trust-endorsed and British Association of Urological Surgeons (BAUS) patient leaflet and distributed amongst the juniors. A total of 28 patients were interviewed via telephone questionnaires – 21 randomly selected pre-intervention and 7 post-intervention from a one-month scale either side of the intervention. The template included: information on stents, common stent symptoms, indications to seek healthcare advice, and contact details to use in the event they are lost to follow-up.

Results

Patients aware that stents should be changed within six months went from 52% to 100%. Awareness of stent symptoms and red-flag symptoms went from 52% to 91%, and 57% to 100% respectively. Those who felt they had sufficient information on the discharge letter to understand their stent increased from 52 to 89%.

Conclusions

Significant improvement in patient understanding of stents and therefore hopefully in appropriate health-seeking behaviour, patient rapport, safety, and improvement in stents removed within target.

Reducing mortality in mucormycosis of the head and neck in diabetic patients: A CARE case series

INTRODUCTION

Rhinocerebral mucormycosis is extremely fatal, with mortality rates ranging from 85-93% despite the best treatment in immunocompromised patients. We emphasize the importance of early diagnosis, repeated debridement, and aggressive antifungal treatment to reduce mortality.

CASE SUMMARY

We report six cases (five male and one female), with a mean age of 51 years who were diagnosed to have mucormycosis from 2017 to 2019. All patients were diabetic. Intracranial involvement and orbital involvement were found in four cases. Facial nerve palsy was seen in two cases, one without any apparent otological involvement. Aggressive serial debridement and amphotericin B was started. Posaconazole was added subsequently to the treatment in two cases. One patient succumbed to the disease five months after discharge. The other five patients are on regular follow-up for a mean duration of 14 months at the end of which two had residual disease which was under control.

DISCUSSION

Repeated surgical debridement with an early aggressive and combination antifungal therapy can result in good outcomes even in advanced mucormycosis. Concurrent management of the underlying pathology, monitoring of liver and kidney functions, and therapeutic drug monitoring are useful to ensure smooth and effective treatment.

Dilemma of diagnosing thoracic sarcoidosis in tuberculosis endemic regions: An imaging-based approach. Part 1

Sarcoidosis is a multi-systemic disorder of unknown etiology, although commonly believed to be immune-mediated. Histologically, it is characterized by noncaseating granuloma which contrasts against the caseating granuloma seen in tuberculosis (TB), an infectious disease that closely mimics sarcoidosis, both clinically as well as radiologically. In TB-endemic regions, the overlapping clinico-radiological manifestations create significant diagnostic dilemma, especially since the management options are markedly different in the two entities. Part 1 of this review aims to summarize the clinical, laboratory, and imaging features of sarcoidosis, encompassing both typical and atypical manifestations, in an attempt to distinguish between the two disease entities.

Dilemma of diagnosing thoracic sarcoidosis in tuberculosis-endemic regions: An imaging-based approach. Part 2

The second part of the review discusses the role of different existing imaging modalities in the evaluation of thoracic sarcoidosis, including chest radiograph, computed tomography, magnetic resonance imaging, endobronchial ultrasound, and positron emission tomography. While summarizing the advantages and pitfalls of each imaging modality, the authors propose imaging recommendations and an algorithm to be followed in the evaluation of clinically suspected case of sarcoidosis in tuberculosis-endemic regions.

Radiology of anal and lower rectal cancers

Lower rectal and anal cancers are distinct from neoplasms involving rest of the rectum. These are relatively difficult to manage owing to important relationships with the sphincter muscles. Involvement of the latter portends a poorer prognosis and increased chance of recurrence. Lymphatic drainage of these tumours is into the systemic circulation and the exact set of lymph nodes involved depends on the precise location of the tumour. The role of imaging includes assessment of local invasion, infiltration of adjacent pelvic organs, assessment of locoregional lymphatic spread and metastasis, post-chemoradiation restaging as well as post-treatment surveillance.

Screening for second malignancies in mycosis fungoides: non-Hodgkin lymphoma, Hodgkin lymphoma, lung cancer, bladder cancer and melanoma

BACKGROUND

Patients with mycosis fungoides (MF) are at increased risk of developing non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), lung cancer, bladder cancer and melanoma. The characteristics of patients developing these malignancies have not been specifically delineated. In addition, there are no established guidelines for screening MF patients for second malignancies.

MATERIALS/METHODS

We identified 742 patients with MF who developed second malignancies in the Surveillance Epidemiology and End Result-18 database.

RESULTS

The majority of second malignancy patients were white and male, mean age 55-67 years at diagnosis of MF, and mean age 61-72 years at diagnosis of second malignancy. The majority of patients diagnosed with second malignancies had early stage MF. MF patients with NHL, lung cancer, and bladder cancer tended to be diagnosed at earlier stages of the second malignancy than patients without MF and demonstrated better 5-year overall survival. There was no improvement in stage at diagnosis or survival for MF patients who were diagnosed with melanoma compared to patients without MF.

CONCLUSIONS

Improvements in survival in MF/NHL, MF/lung cancer and MF/bladder cancer patients may reflect differences in disease biology secondary to having MF or the importance of increased contact with the healthcare system. MF/melanoma data suggest that patients require regular pigmented-lesion-focused skin examinations. Tools for screening include regular lymph node examinations, pigmented-lesion-focused examinations and detailed review of systems questions. Smoking cessation counseling is key intervention in this population, as is ensuring that all age- and sex-specific cancer screenings are up-to-date (e.g. lung cancer screening, mammography, and colonoscopy). The utility of regular imaging for second malignancy screening and lab testing such as routine urinalysis requires additional study and expert consensus.

Experimental analysis of solar powered disinfection tunnel mist spray system for coronavirus prevention in public and remote places

There is a pressing need to accelerate the development of advanced technologies to prevent Coronavirus in large gatherings. The present system is an integration of tunnel disinfectant spray system and solar setup which utilises the solar energy to power a pump which pushes the required amount of chemical mixture into the nozzles of the spray system in order to eliminate any incoming virus or bacteria on the clothes of a particular person without wetting it. Data was gathered for a mall in New Delhi related to occupancy levels before and after lockdown. A 47% and 35% spike in energy and disinfectant mixture to pump was evaluated on weekends. A 70% reduction in operating cost was registered for solar based system in comparison to non-solar setup. Optimum conditions by considering efficiency and cost effectiveness evaluated are 8 number of nozzles, nozzle angle 55 degrees spray pressure 200 bar, and pressure 200 bar.

Reducing admission hypothermia in newborns at a tertiary care NICU of northern India: A quality improvement study

BACKGROUND

Hypothermia at admission to neonatal intensive care units (NICU) is associated with increased morbidity and mortality in newborns. A baseline study at a tertiary care hospital with all out-born babies showed admission hypothermia of 82%.

OBJECTIVE

To reduce admission hypothermia (moderate) in newborns at least by 50% in next 6 months.

METHODS

A quality improvement (QI) study was planned using WHO Point of Care Quality Improvement Model (POCQI), [17] using PDSA (Plan-Do-Study-Act) cycle approach from April 2018 to March 2019, and including 427 term and preterm babies. We educated the staff, reinforced the use of caps, cling wraps, warm linen, introduced Ziploc bags and ensured adequate use of transport incubator.

RESULTS

After 6 months, overall admission hypothermia decreased from 82% to 45%, moderate hypothermia reduced from 46% to <10% (P < 0.001) and severe hypothermia (3%) was completely eliminated. There was also significant reduction in incidence of Intraventricular hemorrhage (13% Vs 4.7%), Late onset neonatal sepsis (38% Vs 19%) and metabolic acidosis (43% Vs 28%). We were able to sustain this improvement for the next 6 months and is ongoing. The strongest predictor of hypothermia was newborns being in the phase before QI initiative was started (OR 2.36, 95% CI 1.47, 3.23).

CONCLUSION

This study is a cost effective approach in reducing admission hypothermia in NICU in a resource limited setting with all outborn babies, and further decreasing the morbidity associated with it. Hence, emphasizing the importance of maintaining euthermia, not only in delivery rooms, but also during transportation.

High burden of cardiometabolic risk factors in spouses of Indian women with hyperglycaemia in pregnancy

AIM

To evaluate the burden and association of cardiometabolic risk factors in the spouses of women with and without hyperglycaemia in pregnancy.

METHODS

Women with (n = 204) and without (n = 197) hyperglycaemia in pregnancy, along with their spouses, participated in this cross-sectional study. The hyperglycaemia in pregnancy group included women with gestational diabetes and diabetes in pregnancy. A detailed questionnaire was completed for all participants (men and women), documenting relevant personal and medical history, along with biochemical investigations (men).

RESULTS

A total of 401 couples were evaluated at the time point during the pregnancy of 24.7 ± 5.2 gestational weeks (mean ± sd). Dysglycaemia (prediabetes or diabetes), overweight/obesity (BMI ≥25 kg/m² ) and metabolic syndrome were detected in 120 (58.9%), 123 (60.3%) and 98 spouses (48.3%) of women with hyperglycaemia in pregnancy, respectively. In the fully adjusted model, an increased risk of dysglycaemia [odds ratio 1.43 (95% CI 0.95-2.17); P = 0.088], overweight/obesity [odds ratio 1.49 (95% CI 0.98-2.27); P = 0.064] and metabolic syndrome [odds ratio 2.00 (95% CI 1.30-3.07); P = 0.001] was seen in the spouses of women with hyperglycaemia in pregnancy. The prevalence of these metabolic conditions was higher in spouses of women with diabetes in pregnancy compared to spouses of women with gestational diabetes mellitus.

CONCLUSIONS

A high burden of cardiometabolic risk factors was observed in the spouses of women with hyperglycaemia in pregnancy. The opportunity provided by pregnancy could be used by the healthcare system not only to improve the health of the woman and her offspring, but also her spouse.

Cardiological society of India document on safety measure during echo evaluation of cardiovascular disease in the time of COVID-19

An echocardiographic investigation is one of the key modalities of diagnosis in cardiology. There has been a rising presence of cardiological comorbidities in patients positive for COVID-19. Hence, it is becoming extremely essential to look into the correct safety precautions, healthcare professionals must take while conducting an echo investigation. The decision matrix formulated for conducting an echocardiographic evaluation is based on presence or absence of cardiological comorbidity vis-à-vis positive, suspected or negative for COVID-19. The safety measures have been constructed keeping in mind the current safety precautions by WHO, CDC and MoHFW, India.

Mycosis fungoides: developments in incidence, treatment and survival

BACKGROUND

Prior studies have demonstrated improved disease-specific survival of mycosis fungoides (MF) patients over the last 50 years.

OBJECTIVE

To analyse patterns of survival and incidence from 1973 to 2016 and determine whether apparent improvements in MF-specific survival are due to lead-time bias rather than improvements in treatment.

METHODS

We performed an analysis of 10 155 patients diagnosed with MF from 1973 to 2016 in the United States cancer registries of SEER-18. We also performed a literature review of papers including stage data for unselected populations of MF patients prior to 2000.

RESULTS

Incidence of MF increased from 3.0 per million person-years in the 1970s to 5.9 in the 2010s. For all cohorts, non-Hodgkin lymphoma (including MF) was the leading cause of death. Survival analysis demonstrated marked improvement in disease-specific and overall survival from the 1970s to 2010s. Based on systematic review of the literature, 32%-73% of patients diagnosed prior to 2000 were diagnosed with early-stage disease, as opposed to 81% of patients in the SEER 2000-2016 cohort (P < 0.035 for all cohorts).

CONCLUSIONS

Although there have been improvements in MF-related survival over the last 50 years, these may reflect improvements in our ability to diagnose early-stage disease rather than improved treatment.

Lyme Disease: What the Neuroradiologist Needs to Know

Knowledge of Australian primary education providers towards dental avulsion injuries: a cross-sectional study

BACKGROUND/AIM

The aim of this study was to evaluate the knowledge of school professionals regarding the emergency management of dental avulsion.

METHODS

This cross-sectional study utilised a self-administered, pilot-tested questionnaire for school staff from primary schools. Descriptive statistics were used for the analysis - the prevalence and univariate associations between a categorical outcome and the variables under consideration, were evaluated using Pearson's Chi-squared test.

RESULTS

This survey yielded a response rate of 43.5% (n = 313). Approximately 60% of participants held valid first-aid certificates and 23% had received avulsion advice previously. Over 80% of participants expressed an unwillingness to replant an avulsed tooth, and over 90% believed that there should be greater awareness in this area. This unwillingness to replant was influenced by respondents' age (x2 = 8.13 df = 3, P = 0.043) and receiving advice previously (x2 = 13.15, df = 1, P < 0.001). Under-preparedness was related to years of experience (x2 = 15.03, df = 5, P = 0.010), first-aid training (x2 = 6.41, df = 1, P = 0.011) and receiving advice previously (x2 = 43.47, df = 1, P < 0.001). It was also evident that first-aid training positively influenced appropriate dental referral in the management pathway (x2 = 10.49, df = 1, P = 0.001).

CONCLUSION

This study suggests that there is an inadequate level of knowledge on the appropriate management of dental avulsion injuries amongst primary school professionals in Australia.

Use of Fluoridated Dentifrices among Children: Are We in the Right Direction?

Introduction Use of topical fluorides in dentifrices has always been an important tool in prevention of dental caries in young children. Due to the easy availability of various low and high fluoride dentifrices, the parents have no clear understanding about their correct age-appropriate use in children. This study was undertaken to evaluate and understand the trend and current practices among the end user.

Materials and Methods A total of 173 children aged 4 to 6 years were enrolled in the study from schools located in two different geographical areas of the Chandigarh city; group 1 (n = 90) from a peri-urban slum cluster: (Govt. Primary School, Indira Colony, Mani Majra, n = 51); Govt. Middle School, Mani Majra (n = 39); group 2 (n = 83) from an urban private city school (Ankur, Punjab University, Sector 14) using cluster sampling method. Two examiners using type IV examination examined all the children aged 4 to 6 years present using a preinstructed close-ended questionnaire. Data were analyzed using SPSS Software Version 25 (SPSS Inc., Chicago, IL, United States).

Results The data regarding the knowledge of fluoride in pastes showed that 85% of the children were using high fluoride pastes, 10% were using nonfluoride pastes, and 5% were using low fluoride pastes. In group 1, none of the users were aware about the benefits/risk of using fluoride toothpastes and only 22% were aware in group 2. Only 27% of children in group 1 dispensed the correct amount of dentifrice for this age group i.e., a pea head size versus 67% in group 2; a half brush length was dispensed by 61.5% in group 1 and 28% in group 2, and just a smudge by 11.5% in group 1 and 5% in group 2. Forty one percent children in both the groups had a history of having intentionally consumed the toothpaste. The toothpaste was dispensed to the child by parent in 89% of cases in group 2 and only 50% in group 1 and 88% parents claimed to always supervise the child while tooth brushing versus only 53% in group 1. Majority of the respondents’, i.e., 97% in group 1 and 63% in group 2 had never been explained about the correct method of use of fluoride paste in children.

Conclusion Knowledge about fluoridated toothpastes is low among the population. The children in peri-urban slums areas are exposed to the high fluoride pastes from very early in life and there is no other toothpaste which is brought home except for those which are commonly used among the members. In the city schools; however, a small percentage of population uses low fluoride pastes in children, possibly due to a greater awareness and access to information, but has no clear idea about their limitations and benefits of age-appropriate use. Till appropriate guidelines are available for the country, a safe practice to follow is tailoring individual need based protocol. The children in peri-urban slums areas need to be educated more on the health practices and importance of use of fluoride dentifrices and the children in the city schools need to be guided more on the age appropriate use of high and low fluoride dentifrices.

Efficacy of electromotive drug administration in delivering botulinum toxin a in children with neuropathic detrusor overactivity-outcomes of a pilot study

BACKGROUND

Intravesical botulinum toxin A (BtA) injection is well established in managing paediatric neuropathic detrusor overactivity (NDO). Electromotive drug administration (EMDA) is a less invasive method, which can be performed in the clinic, using pulsed electrical current for drug delivery via a urethral catheter. Few small studies report good outcomes following BtA via EMDA (BtA/EMDA) into bladders of children with NDO.

OBJECTIVE

The objective of this study is to assess the efficacy of BtA/EMDA in children with NDO, reduced bladder capacity and compliance.

METHODS

Twelve children with NDO on baseline urodynamic study were prospectively included. Pre-BtA/EMDA and post-BtA/EMDA results compared the following four parameters: maximal cystometric capacity, bladder compliance, maximal detrusor pressure (pDetmax) during detrusor overactivity and pDetmax at capacity. The Wilcoxon matched-pairs signed-rank test using Graphpad Prism 8 was used for analysis. Secondary outcomes include adverse effects and symptomatic improvement.

RESULTS

Fourteen episodes of BtA/EMDA were performed. Five patients received 3.3 IU/kg of Botox®, and five received 10 IU/kg (maximum 300 IU). Four patients received 10 IU/kg of Dysport®. Two patients in the Dysport®/EMDA group also received Botox®/EMDA more than six months previously. Thirteen of 14 post-EMDA results were completed and included in the paired analysis. No statistically significant improvements in any cystometric parameters were demonstrated. Eight patients subsequently had intravesical BtA injections with significant improvements in both cystometric parameters and symptoms. Two patients subsequently transitioned to adult services; one was commenced on mirabegron, and one has undergone ileocystoplasty with Mitrofanoff appendicovesicostomy.

DISCUSSION

Despite some evidence to support BtA/EMDA in children with NDO, the authors were unable to replicate previously published positive cystometric and symptomatic outcomes. In addition, BtA/EMDA performed poorly when compared with conventional intravesical BtA injections. This implies failure of EMDA to deliver BtA correctly to the target tissue. The large size of the BtA molecule or the abnormal bladder wall in NDO could account for the negative results. Thorough preparation and consultation was undertaken before this study with BtA/EMDA, and it is discouraging that the authors were unable to reproduce the positive results of other groups.

CONCLUSIONS

Although safe and acceptable to most patients, the authors cannot recommend the use of BtA/EMDA for NDO in children at present.

P4632Impact of intracardiac thrombosis in patients with acute myocardial infarction: insights from nationwide inpatient sample in the United States

Background

Intracardiac thrombosis (ICT) is a complication of Acute myocardial infarction (AMI).

Hypothesis

Our aim was to evaluate the impact of ICT on mortality, thromboembolism, length of stay in patients with AMI.

Methods

Data was collected from the Nationwide Inpatient Sample (NIS) for the year 2016, where patients with a primary diagnosis of ICT as a complication of AMI (ICD10-CM code I23.6) were included. Comparisons were made between patients with ICT post-AMI (ICD10-CM code I23.6) vs those with AMI (ICD10-CM I21.0).

Results

Of a total of 200930 cases of AMI, 488 (0.5%) had ICT. The patients with ICT had an increased length of stay (LOS) (8.5±9.8 vs 5.7±7.4 days; p<0.001), increased ischemic stroke (10.6% vs 2.9%; p<0.001), and cardiogenic shock (15% vs 7%; p<0.001). There was no difference in mortality between the groups.
