Beyond HbA1c: Identifying Gaps in Glycemic Control Among Children and Young People with Type 1 Diabetes Using Continuous Glucose Monitoring

OBJECTIVES

To describe continuous glucose monitoring (CGM) derived glycemic variables, and study their association with HbA1c and socio-economic factors in young people with Type 1 diabetes mellitus (T1DM).

METHODS

Ninety-two participants [age 15.7 ± 5.0 y (mean ± SD), HbA1c 8.0 ± 1.5% (mean ± SD)] wore a professional CGM sensor for 14 d.

RESULTS

Median (IQR) time in range (TIR) was 41 (18)%. Participants spent 41 ± 20% of their day in hyperglycemia (>180 mg/dl), and 14 (13)% in hypoglycemia (<70 mg/dl). High glycemic variability (percent CV >36%) was seen in 92% participants. Older age at diagnosis was associated with higher TIR (β = 0.267, p = 0.01), lower time above range (TAR) (β = -0.352, p <0.001), but higher time below range (TBR) (β = 0.274, p = 0.006). The use of NPH vs. glargine basal insulin was associated with higher TBR (β = -0.262, p = 0.009) but lower TAR (β = 0.202, p = 0.041). HbA1c showed negative correlation with TIR (r = -0.449, p <0.001) and TBR (r = -0.466, p <0.001) and positive correlation with TAR (r = 0.580, p <0.001) and mean glucose (r = 0.589, p <0.001).

CONCLUSIONS

These data demonstrate wide gaps between the recommended vs. real world glycemic variables in patients with T1DM in this region on multiple daily insulin injections. CGM identifies glycemic variability and complements HbA1c in improving glycemic control.

Basic carbohydrate counting and glycemia in young people with type 1 diabetes in India: A randomized controlled trial

OBJECTIVES

The aim of this study was to evaluate the effect on glycemic control and acceptability of basic carbohydrate counting (BCC) in children and young adults with type 1 diabetes (T1DM).

METHODS

Ninety-two children and young adults (6-25 y of age) with T1DM were randomized to receive either routine nutrition education (RNE), which addressed food groups, glycemic index, and effects of food and exercise on glycemia, or learn BCC with personalized portion size education. A continuous glucose monitoring study and glycosylated hemoglobin (HbA1c) were performed at baseline and after 12 wk. The primary outcome was a change in time-in-range from baseline through 12 wk. A questionnaire on the acceptability of BCC was administered.

RESULTS

At 12 wk, there was no significant difference in change in time-in-range between the two groups (BCC group: 1.2 ± 12.2; RNE group: 1.9 ± 12.3; P = 0.786). No significant changes were observed in the percentage of time that blood glucose was >180 or >250 mg/dL; <70 or <54 mg/dL; glycemic variability, percentage of nights with hypoglycemia and HbA1c. In subgroup analysis, there was a significant decrease in HbA1c in the BCC group among participants with higher maternal education (-0.5 versus 0.2, P = 0.042). The total score on the acceptability questionnaire was higher in the BCC group (P = 0.022).

CONCLUSION

Among children and young adults in our region with T1DM, BCC provided flexibility in food choices and perception of greater ease of insulin adjustment. Although BCC was equivalent to RNE in terms of glycemic control, larger studies may reveal benefit in outcomes in certain subgroups.

Enhancement in the dielectric and magnetic properties of Ni2+-Cu2+ co-doped BaFe11Cu1-xNixO19 hexaferrites (0.0 ≤ x ≤ 1.0)

Herein, Ni2+-Cu2+ co-doped barium hexaferrites (BaFe11Cu1-xNixO19, 0.0 ≤ x≤ 1.0 with an interval of 0.25) were successfully synthesized using a co-precipitation method. The formation of a magnetoplumbite structure with the P63/mmc space group was confirmed by Rietveld refinement of the obtained X-ray diffraction patterns. Microstructural investigations revealed grains in the shape of hexagonal plates, while co-doping resulted in a variation in the grain sizes of the prepared samples. X-ray photoelectron spectroscopy was performed to determine the valence state of iron in the prepared hexaferrites. Impedance spectroscopy analysis revealed that dielectric permittivity initially decreased with an increase in the co-dopant content up to x = 0.5 and then increased by two orders of magnitude for x = 1.0. Alternatively, resistive properties showed microstructural resistance values in the range 105-108 Ω, with the highest value obtained for the sample with x = 0.5. Furthermore, magnetic measurements indicated that all the prepared samples exhibited ferrimagnetic behaviour. Saturation magnetization and magnetic anisotropy values were found to be the highest for the sample with x = 1.0, which also had the lowest coercivity among the prepared samples. Herein, the observed variations in the obtained results can be explained by the variations in grain sizes and the Fe2+/Fe3+ ratio associated with the preferential occupation of co-dopants at octahedral sites. Based on our findings, the BaFe11Ni1O19 (x = 1.0) composition appears to be the most promising choice as a microwave absorption material among the prepared samples owing to the coexistence of high dielectric permittivity (>103 at 107 Hz) and saturation magnetization (73 emu g-1).

Natural history of occult hernias in adults at a safety-net hospital

PURPOSE

Occult hernias, hernias seen on radiologic imaging but not felt on physical exam, are common. Despite their high prevalence, little is known about the natural history of this finding. Our aim was to determine and report on the natural history of patients with occult hernias including the impact on abdominal wall quality of life (AW-QOL), need for surgery, and risk of acute incarceration/strangulation.

METHODS

This was a prospective cohort study of patients who underwent a computed tomography (CT) abdomen/pelvis scan from 2016 to 2018. Primary outcome was change in AW-QOL using the modified Activities Assessment Scale (mAAS), a hernia-specific, validated survey (1 = poor, 100 = perfect). Secondary outcomes included elective and emergent hernia repairs.

RESULTS

A total of 131 (65.8%) patients with occult hernias completed follow-up with a median (IQR) of 15.4 (22.5) months. Nearly half of these patients (42.8%) experienced a decrease in their AW-QOL, 26.0% were unchanged, and 31.3% reported improvement. One-fourth of patients (27.5%) underwent abdominal surgery during the study period: 9.9% were abdominal procedures without hernia repair, 16.0% involved elective hernia repairs, and 1.5% were emergent hernia repairs. AW-QOL improved for patients who underwent hernia repair (+ 11.2 ± 39.7, p = 0.043) while those who did not undergo hernia repair experienced no change in AW-QOL (- 3.0 ± 35.1).

CONCLUSION

When untreated, patients with occult hernias on average experience no change in their AW-QOL. However, many patients experience improvement in AW-QOL after hernia repair. Additionally, occult hernias have a small but real risk of incarceration requiring emergent repair. Further research is needed to develop tailored treatment strategies.

Kenyan palliative care providers' and leaders' perceptions of palliative care research needs and support to facilitate rigorous research

BACKGROUND

Palliative care (PC) can reduce symptom distress and improve quality of life for patients and their families experiencing life-threatening illness. While the need for PC in Kenya is high, PC service delivery and research is limited. Qualitative research is needed to explore potential areas for PC research and support needed to enable that research. This insight is critical for informing a national PC research agenda and mobilizing limited resources for conducting rigorous PC research in Kenya.

OBJECTIVES

To explore perceptions of priority areas for PC research and support needed to facilitate rigorous research from the perspective of Kenyan PC providers and leaders.

METHODS

Focus groups (FGs) were conducted in November and December of 2018 using a semi-structured interview guide. FGs were audio-recorded, transcribed, and analyzed using a thematic content analysis approach.

RESULTS

Three FGs were conducted (n = 22 participants). Ten themes related to PC research emerged, including research on: 1) beliefs about death, disease, and treatment to inform PC; 2) awareness about PC, 3) integration of PC within the health system; 4) understanding caregiver experiences and needs; 5) community health volunteers (CHVs) and volunteer programs; 6) evaluation of costs and benefits of PC; 7) treatment approaches, including complementary and alternative medicine (CAM) and advanced diagnostics at end of life; 8) other suggestions for research, 9) populations in need of PC research; and 10) resources for enabling research.

CONCLUSIONS

Kenyan PC providers and leaders identified key areas requiring increased scientific inquiry and critical resources needed to enable this research. These findings can help to focus future PC research in Kenya and encourage funding agencies to prioritize the issues identified.

Fabrication of La3+ doped Ba1-x La x TiO3 ceramics with improved dielectric and ferroelectric properties using a composite-hydroxide-mediated method

Lanthanum (La³⁺) doped Ba_1-x La _x TiO₃ (x = 0.0, 0.0025, 0.005, 0.0075) ceramics were synthesized by the composite-hydroxide-mediated method. Rietveld refinement of the XRD patterns confirmed the formation of a perovskite crystal structure that transforms from tetragonal to pseudo-cubic with La³⁺ doping content (x). Scanning electron microscopy displayed a dense and homogeneous microstructure with reduced grain size on La³⁺ doping. The frequency and temperature-dependent dielectric measurements showed an improvement in the dielectric permittivity, a decrease in the ferroelectric-paraelectric transition temperature, and an increase in the dielectric diffusivity with increasing La³⁺ doping content. Complex impedance analysis indicated the semiconducting behavior with a positive temperature coefficient of resistance effect, which could be explained in terms of a charge compensation mechanism in the donor doped BaTiO₃. The ferroelectric hysteresis loops revealed that these ceramics are ferroelectric in nature, while an improvement in the energy storage density and energy storage efficiency was observed for the doped samples due to reduced grain size on La³⁺ doping. Here, the sample with x = 0.005 has a high dielectric permittivity, a low dielectric tangent loss, and the highest energy storage efficiency. This makes this composition interesting for energy storage applications.

Adults with concomitant atopic dermatitis and asthma have more frequent urgent health care utilization and less frequent scheduled follow-up visits than adults with atopic dermatitis or asthma only: A nationwide cohort study

BACKGROUND

Atopic dermatitis (AD) and asthma often co-occur in the same patient, and health care utilization is related to disease severity of these diseases.

OBJECTIVE

To investigate differences in healthcare utilization in adults with concomitant AD and asthma compared to patients with asthma or AD only.

METHODS

All Danish adults with a hospital-diagnosis of AD, asthma or concomitant AD and asthma recorded in national registries were included. Health care utilization data were obtained in 3-month intervals from two year prior to index date (the date of the first hospital diagnosis), and to five years after.

RESULTS

A total of 12,409 patients with AD were included (11,590 with AD only and 819 with concomitant AD and asthma), and 65,539 with asthma only. Adults with concomitant AD and asthma had higher risk of hospitalization for AD (OR 1.38, 95% CI (1.15-1.67), p=0.001) and asthma (OR 1.16, 95% CI (1.00-1.35), p=0.047) compared to patients with only AD and asthma, respectively. These patients also had fewer visits in outpatient clinics for AD (OR 0.10, 95% CI (0.08-0.12), p<0.001) and asthma (OR 0.34, 95% CI (0.29-0.39), P<0.001) compared to patients with only AD or asthma. Outpatient clinic visits for rhinitis were more frequent among patients with concomitant AD and asthma compared to patients with only AD or asthma.

CONCLUSION

Adults with concomitant AD and asthma had different patterns of healthcare utilization compared to adults with AD or asthma alone, suggesting that improvements in management and monitoring may reduce unscheduled health care visits, and lower healthcare costs.

P-738 Impact of limited reproductive health awareness on PCOS diagnosis timelines and the need for improved patient education

Study question

Does the lack of awareness of Polycystic ovary syndrome (PCOS) symptoms contribute to a delay in diagnosis?

Summary answer

Limited awareness regarding reproductive health symptoms can negatively impact help-seeking behaviour, delaying diagnostic timelines.

What is known already

PCOS is a common endocrine condition estimated to affect up to 20% of women worldwide. Frequently observed symptoms include oligomenorrhea or amenorrhea, clinical features of hyperandrogenism, metabolic dysfunction, infertility and poor mental health.

Despite its prevalence and the debilitating impact of symptoms on quality of life, it takes an average of two years and over three clinical consultations to diagnose. Delayed diagnosis may be influenced by a lack of standardised screening guidelines, poor understanding of how PCOS manifests in ethnic minorities and hesitancy from the general public to seek help for their reproductive health symptoms.

Study design, size, duration

A cross-sectional study investigating the barriers to diagnosis of PCOS.

Participants aged 18 or older with an existing or suspected diagnosis of PCOS were invited to complete an online survey across five days in January 2022.

The survey assessed general demographic information, the influence of symptoms on their daily life and their experiences with receiving a diagnosis.

Of the 200 responses, 143 responses were analysed and 99 were included in the results.

Participants/materials, setting, methods

Participants were aged between 18 - 45 and provided informed consent after reading a patient information leaflet detailing the background of the study.

75 (52.44%) participants were UK-based, while 68 (47.55%) were based abroad.

Ethical approval of all study-related documents was given by the Hertility Health Research Ethics Committee.

The online survey was presented on Typeform and disseminated via the social media platforms Instagram, Twitter and LinkedIn.

Descriptive statistics are presented.

Main results and the role of chance

Of the 143 participants, 99 (69.2%) reported a PCOS diagnosis. Anxiety (71.4%), irregular menstrual cycles (69.4%) and weight-related concerns (64.3%) were the most commonly reported symptoms.

Despite the majority reporting that their symptoms impacted daily life (80.8%), mental health (82.8%), and educational or work performance (70.7%), only 10.2% had sought medical help immediately while 75.5% waited for up to 2 years.

Not realising their symptoms required medical help (73.2%), lack of information regarding routes to care (18.3%) and stigma from family members (18.3%) were the most common reasons why medical help was not sought immediately.

Following clinical consultations, 54.7% of participants were not satisfied with the information provided to manage their diagnosis. Although mental health-related symptoms were most frequently reported (75.5%), only 4.8% reported that management strategies for mental health were referenced in their consultations.

Of the 93.2% of those looking for extra information online, only 52.3% used official websites such as the National Health Service (NHS) website. Many participants also chose to use social media sources such as Instagram and Tik Tok for information (52.3%) and support (59.3%).

Limitations, reasons for caution

Although there was a global uptake, the study needs to be carried out on a larger scale with an emphasis on minority ethnicities.

Recall bias could have also impacted findings as the participants were required to provide details on their entire diagnosis experience.

Wider implications of the findings

It is evident that limited awareness regarding reproductive health can delay the diagnosis of PCOS.

Due to unsatisfactory management by healthcare providers, patients heavily rely on unregulated channels such as social media to obtain reproductive health information, highlighting the need for better Sex and Fertility Education programs and improved accessibility.

Unusual semiconductor-metal-semiconductor transitions in magnetite Fe3O4 nanoparticles

Magnetite (Fe₃O₄) nanoparticles were successfully prepared by a co-precipitation method. Rietveld refinement on the X-ray diffraction pattern confirmed the development of a single-phase cubic spinel structure with space group Fd3̄m. However, ⁵⁷Fe Mössbauer spectroscopy suggested the presence of Fe³⁺ and Fe^2.5+ (mixed Fe³⁺ and Fe²⁺) ions at the tetrahedral and octahedral sites of the inverse spinel structure, respectively. Impedance spectroscopy measurements showed a discontinues variation in the temperature dependence of the sample's resistive behavior, indicating the appearance of semiconductor–metal–semiconductor like transitions between the temperature range of 293 and 373 K. A similar dual transition was also observed from the dielectric and conductivity measurements around the same temperature regions. The observed unusual transition is explained in term of the competitive effects among the hopping of localized/delocalized and short-range/long-range charge carriers present in the sample. Moreover, the prepared sample exhibits colossal dielectric permittivity (∼10⁶), reduced tangent loss (∼0.2) and moderate conductivity (>10⁻⁶ S cm⁻¹) values, making Fe₃O₄ nanoparticles a potential candidate for electromagnetic absorbing materials.

Herein, we report the existence of a novel semiconductor–metal–semiconductor type transition in Fe₃O₄ nanoparticles by employing impedance spectroscopy techniques.

Improving and Sustaining the Quality of Discharge Summaries

High quality discharge information communication has been linked to a reduction in the incidence of adverse events, decreasing the risk of prescription errors and lost follow up. In this paper we describe how our trust-wide quality improvement project, led by acute physicians, successfully improved discharge documentation. We demonstrate how we identified obstacles to continued success, and the interventions we implemented. We recommend how discharge summary quality can be optimised through training of junior doctors, recruitment of local champions, and use of novel methods to preserve engagement, such as gamification.

The interplay of saliva, erosion and attrition on enamel and dentine

Purpose

This investigation aimed to compare the protective role of saliva against erosion and attrition challenges.

Method

Polished enamel and dentine samples (n = 160) were prepared and randomly assigned to either the saliva or saliva-free group (n = 40 enamel and n = 40 dentine/group). Within each subgroup, they were allocated to four subgroups: negative control (deionized water exposure 10 min), erosion (0.3% citric acid 10 min), attrition (120 S of 300 g force), or combined erosion/attrition (0.3% citric acid 10 min then 120 S of 300 g force). Experimental cycles were repeated three times. Data analysis was performed using SPSS.

Results

The mean and standard deviation (SD) of step heights produced by the attrition and erosion/attrition groups in enamel in the saliva-free group were 5.6 µm (2.4) and 13.4 µm (2.8), respectively, while they were 2.4 µm (3.8) and 12.9 µm (3.5) in the saliva group, with no significant difference between the saliva and saliva-free groups. For dentine, the corresponding step heights were 25.2 µm (5.5) and 35.9 µm (7.9) for the saliva-free group, but 21.8 µm (5.3) and 27.3 µm (6.4) for the saliva group (p < 0.001).

Conclusion

There was a trend that saliva decreased wear, but this was only statistically significant for erosion/attrition dentine wear.

Development of laser induced breakdown spectroscopy technique to study irrigation water quality impact on nutrients and toxic elements distribution in cultivated soil

This study is focused mainly on impact of irrigation water quality in cultivated soil on distribution of essentials nutrients (Al, Mg, Ca, Fe, S, Si, Na, P, and K) and relatively toxic metals (As, Ba, Cr, Cu, Ti, Sn, Mn, Ni, and Zn) using an elegant Laser induced breakdown spectroscopy (LIBS) technique. A pulsed Nd:YAG laser operating at 1064 nm in conjunction with suitable detector was applied to record soil emission spectra. The abundance of these elements were evaluated via standard calibration curve Laser Induced Breakdown Spectroscopy (CC-LIBS) and calibration free Laser Induced Breakdown Spectroscopy (CF-LIBS) approaches. Quantitative analyses were accomplished under conjecture of local thermodynamic equilibrium (L.T.E) and optically thin plasma. The average electron temperatures were estimated by Boltzmann plot method for cultivated soil samples in 7800 to 9300 K range. The electron number density was ~ 1.11 × 1017 cm − 3 to 1.60 × 1017 cm − 3. Prior to application on soil samples, the experimental setup was optimized at the following parameters: pulsed energy = 60 mJpulse-1, sample to lens distance of 9.0 cm, and the gate delay of 3.5 μs. It is noteworthy that nutritional elements content of cultivated soils were found strongly dependent upon the irrigation water quality. The cultivated soil from industrial area was found rich of toxins while the cultivated land using tube well water contains toxins in least amount. Our LIBS findings were also validated by comparing its results with contents measured using a standard inductively coupled plasma optical emission spectroscopy (ICP-OES) method and both were found in excellent agreement. The present study could be highly beneficial for agricultural applications and for farmers to produce safe food products and higher crops yield.

Comorbid mental health issues in patients with pemphigus vulgaris and pemphigus foliaceus

The term 'pemphigus' refers to chronic autoimmune skin disorders that cause blistering erosions on the skin and oral mucosa. The two major clinical forms are pemphigus vulgaris and pemphigus foliaceus. Although rare, they confer a stark symptomatic burden upon patients that significantly impacts daily life. Comorbid mental health issues are not routinely screened for in patients with pemphigus, and current UK guidance provides no formal provision for the identification and treatment of psychological issues. This review is the first of its kind, to our knowledge, to systematically examine the available evidence on mental health issues in pemphigus. Published work suggests that the incidence of anxiety and depression is much higher in patients with pemphigus compared with both the general population and with patients having other chronic skin disorders. Disease severity appears to be closely linked to mental health, with worsening of pemphigus associated with deteriorations in psychological wellbeing. Corticosteroids, which are associated with depression in chronic use, are the current first-line therapy for pemphigus and have been identified as a potential confounder and independent risk factor for mental health comorbidity in pemphigus. Current evidence is unclear whether a bidirectional relationship exists between mental health and pemphigus severity, and more thorough research is required to develop understanding of this issue. In conclusion, we have identified a high incidence of mental health comorbidity in pemphigus, and recommend routine screening of patients with pemphigus for mental health issues and signposting toward mental health services as an initial measure to address this.

Immunotherapy and Systemic Therapy in Metastatic/Recurrent Endometrial and Cervical Cancers

Despite advances in the treatment of gynaecological malignancies, both recurrent endometrial and cervical cancers when not amenable to localised therapy (surgery or radiotherapy), remain incurable with limited prognosis and effective treatment options. Chemotherapy remains the standard of care for women with metastatic endometrial or cervical cancers. The addition of bevacizumab to first-line chemotherapy for metastatic cervical cancer patients represents a significant step forward in improving survival. More recently, immunotherapeutic strategies targeting the PD-1/-L1 pathway have shown clinical activity in both endometrial and cervical cancers. The increased understanding of the molecular biology of these cancers is shaping target-specific treatments. Here we summarise current treatment options and results from clinical trials of immunotherapy and other targeted therapies that have already changed, or have the potential to change, clinical practice in metastatic/recurrent endometrial and cervical cancer.

Development, Characterization, and Evaluation of SLN-Loaded Thermoresponsive Hydrogel System of Topotecan as Biological Macromolecule for Colorectal Delivery

BACKGROUND

Chemotherapeutic drugs cause severe toxicities if administered unprotected, without proper targeting, and controlled release. In this study, we developed topotecan- (TPT-) loaded solid lipid nanoparticles (SLNs) for their chemotherapeutic effect against colorectal cancer. The TPT-SLNs were further incorporated into a thermoresponsive hydrogel system (TRHS) (TPT-SLNs-TRHS) to ensure control release and reduce toxicity of the drug. Microemulsion technique and cold method were, respectively, used to develop TPT-SLNs and TPT-SLNs-TRHS. Particle size, polydispersive index (PDI), and incorporation efficiency (IE) of the TPT-SLNs were determined. Similarly, gelation time, gel strength, and bioadhesive force studies of the TPT-SLNs-TRHS were performed. Additionally, in vitro release and pharmacokinetic and antitumour evaluations of the formulation were done.

RESULTS

TPT-SLNs have uniformly distributed particles with mean size in nanorange (174 nm) and IE of ~90%. TPT-SLNs-TRHS demonstrated suitable gelation properties upon administration into the rat's rectum. Moreover, drug release was exhibited in a control manner over an extended period of time for the incorporated TPT. Pharmacokinetic studies showed enhanced bioavailability of the TPT with improved plasma concentration and AUC. Further, it showed significantly enhanced antitumour effect in tumour-bearing mice as compared to the test formulations.

CONCLUSION

It can be concluded that SLNs incorporated in TRHS could be a potential source of the antitumour drug delivery with better control of the drug release and no toxicity.

755 Elective Surgery in the COVID-19 Pandemic: Outcomes of 100 Consecutive Cases

Introduction

The COVID-19 pandemic halted elective surgical activity. Basildon University Hospital established an elective Green Zone for COVID-19 swab negative patients who isolated for 14 days. This study reviewed the outcomes of the first 100 patients.

Method

A single-centre study was performed. Demographic and perioperative electronic data were supplemented with telephone follow-up for the first 100 Green Zone patients and analysed in Microsoft Excel.

Results

One hundred Green Zone patients underwent surgery between 21/05/2020 and 16/06/2020. The median age was 55 (14-88) years. 52% were female. Their operations were performed by General Surgery (39%), Gynaecology (17%), Vascular Surgery (14%), Oral Surgery (12%), ENT (9%), Urology (8%), and Pain Management (1%).

Preoperatively, 100% had a negative SARS-CoV-2 swab and one had CT evidence of mild resolving COVID-19. Two patients had postoperative SARS-CoV-2 swabs, both negative. Median length of stay was 0 (0-7) days. 84% responded to telephone follow-up at a median 25 (13-54) postoperative days, 69% of whom were asymptomatic There were no 30-day major complications (>Clavien-Dindo IIIa) or 90-day mortality.

Conclusions

Elective surgery can be safe during the COVID-19 pandemic, with appropriate measures in place. This has significant implications in the context of an ever-expanding NHS waiting list during a pandemic of uncertain duration.

Thirty-day mortality following surgical management of hip fractures during the COVID-19 pandemic: findings from a prospective multi-centre UK study

PURPOSE

Thirty-day mortality of patients with hip fracture is well researched and predictive; validated scoring tools have been developed (Nottingham Hip Fracture Score, NHFS). COVID-19 has significantly greater mortality in the elderly and comorbid patients which includes hip fracture patients. Non-operative treatment is not appropriate due to significantly higher mortality, and therefore, these patients are often exposed to COVID-19 in the peri-operative period. What is unclear is the effect of concomitant COVID-19 infection in these patients.

METHODS

A multicentre prospective study across ten sites in the United Kingdom (responsible for 7% of hip fracture patients per annum in the UK). Demographic and background information were collected by independent chart review. Data on surgical factors included American Society of Anesthesiologists (ASA) score, time to theatre, Nottingham Hip fracture score (NHFS) and classification of fracture were also collected between 1st March 2020 and 30th April 2020 with a matched cohort from the same period in 2019.

RESULTS

Actual and expected 30-day mortality was found to be significantly higher than expected for 2020 COVID-19 positive patients (RR 3.00 95% CI 1.57-5.75, p < 0.001), with 30 observed deaths compared against the 10 expected from NHFS risk stratification.

CONCLUSION

COVID-19 infection appears to be an independent risk factor for increased mortality in hip fracture patients. Whilst non-operative management of these fractures is not suggested due to the documented increased risks and mortality, this study provides evidence to the emerging literature of the severity of COVID-19 infection in surgical patients and the potential impact of COVID-19 on elective surgical patients in the peri-operative period.

Synthesis of CuO-NPS by simple wet chemical method using various dicarboxylic acid salts as precursors: Spectral characterization and in-vitro biological evaluation

In this study, a simple chemical reduction method was employed to synthesize CuO-NPs.  Various dicarboxylic acids were converted into Cu(II) salt of dicarboxylic acid which were used as precursors. NPs were produced by reducing precursors with NaBH4. Characteristics of synthesized NPs were investigated by using important analytical techniques including Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), thermo gravimetric analysis (TGA) and scanning electron microscopy (SEM). Developed NPs were investigated for their antibacterial activity against a range of bacterial strains by employing agar well diffusion method. CuO-NPs exhibited good to moderate activity against E-Coli, B. Subtilis and poor activity against K. pneumonia and Methicillin-resistant Staphylococcus aureus (MRSA). It was found that amongst all experienced compounds sample 2 showed good activity with minimum inhibition concentration (MIC) 10 µg/mL (zone of inhibition: 22± 0.12 mm) while sample 3 showed poor activity with MIC 40 µg/mL (zone of inhibition: 8.0 ± 0.18 mm).                     KEY WORDS: CuO-NPs, Dicarboxylic acids, Sodium borohydride, Antibacterial study   Bull.

National Clinical Guidance for the Management of Cardiovascular Intervention in the COVID-19 Pandemic: From Bangladesh Society of Cardiovascular Interventions (BSCI)

Since the first recorded case of SARS-CoV-2 in Bangladesh on 8th March 2020, COVID-19 has spread widely through different regions of the country, resulting in a necessity to re-evaluate the delivery of cardiovascular services, particularly procedures pertaining to interventional cardiology in resource-limited settings. Given its robust capacity for human-to-human transmission and potential of being a nosocomial source of infection, the disease has specific implications on healthcare systems and health care professionals faced with performing essential cardiac procedures in patients with a suspected or confirmed diagnosis of COVID-19. The limited resources in terms of cardiac catheterization laboratories that can be designated to treat only COVID positive patients are further compounded by the additional challenges of unavailability of widespread rapid testing on-site at tertiary cardiac hospitals in Bangladesh. This document prepared for our nation by the Bangladesh Society of Cardiovascular Interventions (BSCI) is intended to serve as a clinical practice guideline for cardiovascular health care professionals, with a focus on modifying standard practice of care during the COVID-19 pandemic, in order to ensure continuation of adequate and timely treatment of cardiovascular emergencies avoiding hospital-based transmission of SARS-COV-2 among healthcare professionals and the patients. This is an evolving document based on currently available global data and is tailored to healthcare systems in Bangladesh with particular focus on, but not limited to, invasive cardiology facilities (cardiac catheterization, electrophysiology & pacing labs). This guideline is limited to the provision of cardiovascular care, and it is expected that specific targeted pharmaco-therapeutics against SARS-CoV-2 be prescribed as stipulated by the National Guidelines on Clinical Management of Corona virus Disease 2019 (COVID-19) published by the Director General of Health Services, Ministry of Health and Family Welfare of Bangladesh.

Total body skin examination increases squamous cell carcinoma detection: a retrospective cohort study

Squamous cell carcinomas (SCCs) have the potential for local tissue destruction and metastasis. The risk of complications increases if the lesion is not diagnosed and excised in a timely manner. Total body skin examination (TBSE) has been reported to increase melanoma detection; the objective of this study was to determine if it also increases SCC detection. Analysis of 469 SCCs diagnosed at a UK tertiary centre showed that 6.8% of these were detected incidentally and not from the index lesion that prompted referral. These incidentally detected SCCs tended to represent early disease, and therefore carried lower risk of complications. Our findings suggest that full skin checks may increase the number of SCCs detected, and at an earlier stage of disease. Therefore, we encourage the use of TBSE in all dermatology outpatient appointments, and make suggestions as to how to incorporate it into the limited time available in dermatology clinics.

Comparison of oil and fat supplementation on lactation performance of Nili Ravi buffaloes

The effects of feeding rumen-inert fat sources on production responses of lactating dairy cows have been well reported but less thoroughly described in lactating dairy buffalo. The objective of this study was to investigate the effect of oil and 2 different rumen-inert fat sources on dry matter intake, milk yield, milk composition, and milk fatty acid (FA) profile in Nili Ravi buffalo. Twelve multiparous mid-lactating Nili Ravi buffaloes received 4 treatments in a 4 × 4 Latin square design with a period length of 21 d. The treatments were (1) the basal diet without supplementation of oil or fats (CTRL), (2) the basal diet supplemented with canola oil (CO), (3) the basal diet supplemented with calcium salts of palm FA (Ca-FA), and (4) the basal diet supplemented with high palmitic acid (PA). Dry matter intake was decreased by 4.4% in the CO compared with Ca-FA and PA. Milk yield and milk fat yield were increased by 7.8 and 14.3%, respectively, in CO, Ca-FA, and PA compared with the CTRL. Milk fat content increased by 7.5%, whereas milk fat yield tended to increase with the supplementation of Ca-FA and PA compared with CO. No effect on milk yield and milk composition was observed in Ca-FA versus PA treatments. The yield of medium-chain FA was increased by Ca-FA and PA versus CO. The CO treatment increased the yield of long-chain FA compared with Ca-FA and PA treatments. Plasma glucose level was higher in CO, Ca-FA, and PA compared with the CTRL. In conclusion, feeding rumen-inert fats in the lactating buffalo diet proved to be a useful strategy to increase the 3.5% fat-corrected milk yield due to the higher milk fat content in this study.

Integrating Palliative Care in Cancer Care in Kenya

Background and context: Most Africa countries now recognize the pain and suffering of many patients and families who have no access to cure (where cure is possible), cannot afford treatment of cancer or other progressive chronic illnesses, are stigmatized or discriminated against because of their illness among many other dehumanizing issues. This project aims to ensure that all those in need of palliative care and pain relief have access close to their homes. Aim: This project aims to ensure that all those in need of palliative care and pain relief have access close to their homes. Strategy/Tactics: In the recent past Kenya Hospices and Palliative Care Association has extensively advocated for the integration of palliative care into the Kenya health services; thus, resulting in many health care professionals being trained in palliative care; integration of palliative care in public, private and mission health institutions and integration of palliative care in undergraduate medical and nursing curricula, as well as policy documents. Program/Policy process: The process of integrating palliative care in public hospitals involved advocacy at the national level as well as at the institutional level, training of health care professionals and setting up services within the hospitals that we worked with. Technical support was provided to each individual institution as needed. Outcomes: Palliative care units have been set up in over 25 government hospitals across the country. National Palliative Care Guidelines have been developed. A Diploma in Palliative Care for nurses has been initiated at the Kenya Medical Training College since 2012. Palliative care has been included in all the relevant health policies/strategies. Kenya Essential Medicines List includes Opioids. The Ministry of Health is supplying morphine powder for the country. More patients are now able to access quality palliative care. What was learned: National associations are challenged by an enormous need for services, education and training of health care professionals as well as educating the public and policy makers. The government has no budget for palliative care and most of the work is donor funded. Cultural beliefs are a big barrier to accessing PC. Only a small fraction of patients in need of opioids for pain medication are receiving opioids due to lack of awareness; reluctance of HPCs to prescribe. For many years PC in Kenya has been provided by a few hospices, thus making access very limited to many who are in need. Regional and national associations in Africa should work together with African Ministries of Health and other relevant stakeholders to ensure that there is greater access to palliative care for cancer patients. This encompasses addressing issues of accessibility, affordability, quality palliative care (PC) and a human's right approach to PC.

Determinants of low risk of asthma exacerbation during pregnancy

BACKGROUND

Assessment of asthma control every 4-6 weeks during pregnancy is recommended to reduce risk of exacerbation, and by that improve outcome.

OBJECTIVE

To identify determinants of pregnancies with low risk of asthma exacerbation.

METHODS

All pregnant women enrolled into the Management of Asthma during Pregnancy (MAP) programme at Hvidovre Hospital since 2007. Assessment of asthma control, adjustment of treatment, spirometry and measurement of exhaled nitric oxide (F_E NO) were performed, and baseline characteristics and exacerbation history were collected at enrolment. Determinants of low-exacerbation risk pregnancies were identified by logistic regression analysis (stepwise backward elimination).

RESULTS

In 1283 pregnancies, 107 exacerbations were observed. Multiple regression analysis revealed that no history of pre-pregnancy exacerbations (P < .001), no prescribed controller medication (P < .001), and clinically stable asthma at enrolment (P = .002) were significantly associated with low risk of exacerbation during pregnancy; with these combined characteristics, only two of 385 pregnancies were complicated by an exacerbation (OR 0.04, 95% CI 0.01-0.18, P < .001).

CONCLUSION AND CLINICAL RELEVANCE

Clinically stable asthma at enrolment, together with no history of previous exacerbations and no prescribed controller medication, is a determinant of low risk of an asthma exacerbation during pregnancy, which may guide clinicians in individualizing surveillance of asthma during pregnancy.

Mucocele of appendix with an elevated carcinoembryonic antigen: A case report

Mucocele of the appendix is an uncommon disease in which there is cystic dilatation of the appendix caused by mucus secretion and usually associated with benign or malignant causes. Preoperative diagnosis is difficult as the patient presents with non-specific clinical symptoms. We report a case of mucocele of the appendix with elevated serum carcinoembryonic antigen (CEA) - a condition sparsely reported in literature. Patient presented with pain in the right iliac fossa for 7 months. On exploration, a cystic mass of the appendix without perforation was found in right iliac fossa. There was no lymph nodes enlargement. Appendicectomy was performed with subsequent normalization of CEA level and histopathology confirmed the diagnosis of mucinous neoplasm of the appendix. Patient is feeling well after one year of follow up.
