Pharmacist intervention in cardiovascular disease prevention: lipid modifying treatment optimisation in type 2 diabetes within hastings primary care network

Introduction

Cardiovascular disease (CVD) leads to 1 in 4 premature deaths with higher likelihood in the most deprived population1. Consistent data demonstrated efficacy of statins in CVD prevention and mortality reduction through modifying lipid profile1,2. NICE:CG181 recommends high-intensity statin, namely atorvastatin 20mg daily in type 2 diabetes (T2DM) with high risk of developing CVD1, whilst the European Society of Cardiology suggests LDL-C target below 1.4mmol/L, the lower the better 2. In contrast, 30% of patients in Hastings Primary Care Network (PCN) are prescribed sub-optimal statin therapy3 with scope to promote medicine optimisation through modification of CVD risk factor in one of the England’s most deprived areas.

Aim

Lowering patient’s CVD risk through optimising statin therapy and improving practice’s compliance with NICE:CG181.

Methods

NHS Health Research Authority Decision tool was followed, ethics approval was not required. Statin prescribing data were obtained through OpenPrescribing database. This pilot study focused on the prescribing of simvastatin at one surgery within the PCN where patients were identified using the surgery medical information system with the inclusion clinical codes of: “T2DM”, “QRISK2>10%”, “latest LDL-C>1.4mmol/L” and “current simvastatin 10/20/40mg prescription”. Systematic review of patient medical records was followed, including medical history, latest lipid profile and liver function, allergies, history of statin intolerance, previous lipid therapy and frailty status determined using the electronic frailty index, Rockwood score and medical notes. Patients with heterozygous familial hypercholesterolaemia diagnosis, confirmed statin intolerance and moderately-to-severely frail were excluded. Patients were contacted to exercise shared decision-making. Once intervention agreed, prescription was initiated for prescriber authorisation. Blood test 3 months post-intervention monitored for liver function and lipid profile.

Results

Search in February 2022 identified 44 patients with 39 suitable for intervention after exclusion. Thirty-six contactable patients were all switched to high-intensity statin. Thirty-four were switched to atorvastatin 20 mg whilst two with prior atorvastatin intolerance were switched to rosuvastatin 10 mg. At baseline, 32 patients (88%) had cholesterol profile done within a year as per NICE:CG181. Three-month post-intervention blood tests were completed for 21, with 15 pending; 33% (7/21) had a reduction of LDL-C.

In February 2022, 28.9% of the practice’s statin prescriptions were of low and medium intensity and was reduced to 25.6% post intervention.

Discussion/Conclusion

All contactable patients had statin therapy optimised after exercising shared decision-making with improvement of prescribing compliance to NICE:CG181 demonstrated in this practice. Findings were inconclusive whether the intensification of statin therapy demonstrated cholesterol lowering effect in this cohort. Study limitations due to small sample size, currency of baseline profile at time of intervention and patient compliance not measured. Raised LDL-C observed could have been influenced by lifestyle changes such as poor diet and lack of exercise1. The limitations of this study will be reviewed for future roll out across Hastings PCN. Further exploration of therapy compliance, lifestyle education and the barriers to regular blood test would facilitate such medicine optimisation intervention. In conclusion, patients prescribed with sub-optimal lipid therapy should be reviewed and managed through healthy lifestyle recommendations and aggressive pharmacological intervention.

Apply Molecular Method To Diagnosis A Very Rare Bone Primary Myoepithelial Tumor: A Case Report

Introduction/Objective

A 38-year-old female without a history of trauma and malignancy presented with left knee pain and swelling for two weeks. MRI and PET scan find a left knee mass arising from the bone along the medial metaphysis of the distal femur. She underwent femur resection, and the specimen was sent for pathology evaluation.

Methods

Grossly, the cut surface of the sample revealed a 4.5 x 2 cm area of hemorrhagic softening of the bone with adjacent soft tissue nodules. Microscopically, the tumor showed biphasic or multiphase morphologic features, prominently presented with areas showing well-differentiated epithelial features and other areas with spindling and sheets of tumor cells. Areas suspicious for a vascular invasion were seen at the periphery of the soft tissue extension of the tumor. Immunohistochemistry stains showed the tumor cells are positive for vimentin, AE1/3, EMA, CK7, CK19, GATA3, and BRST2; and are negative for S100, HMB45, GFAP, Calponin, CDX2, PAX8, WT1, P63, CD34, and ER. The molecular test showed positive for the ESWR1 gene but negative for SYT gene translocation.

Results

A diagnosis of primary myoepithelial carcinoma of bone extension into surrounding soft tissue was made.

Conclusion

The most challenging differential diagnosis for this case is metastatic breast cancer. Many of the positive epithelial stains distinctly highlight the epithelial featured geographic areas sparing the background spindled stroma. The positive staining of GATA3 and BRST2, two commonly used breast linage markers, is unusual and not known in myoepithelial carcinoma. In light of the EWSR1 positive and SYT FISH negative results, combined with the morphologic features, locations as well as negative PET scan against its breast origins. Although many myoepithelial markers, such as S100, Calponin, P63, and GFAP were negative, make this case very unique. The molecular diagnosis is the mainstay for this final diagnosis.

Interpersonal sensitivity in the at-risk mental state for psychosis in Karachi, Pakistan

Introduction

Interpersonal sensitivity can be explained as a personality trait in which there is an excessive and expanded awareness of the behavior and emotions of others. Individuals having high interpersonal sensitivity are sensitive to interpersonal relationships and self-deficiencies in comparison to others. Studies report that high interpersonal sensitivity can cause low self-esteem and feelings of insecurity.

Objectives

The objective of this study was to examine the level of interpersonal sensitivity in individuals with an at-risk mental state (ARMS) for psychosis compared to the individuals not at risk for psychosis.

Methods

A total sample of 50 individuals was recruited from Bahria University, Karwan-e-Hayat and Karachi Psychiatric Hospital: 25 with ARMS for psychosis and 25 participants who were not ARMS, according to scores on Schizophrenia Proneness Inventory-Adult (SPI-A). All of the participants then responded to self-report questionnaire on Interpersonal Sensitivity Measure.

Results

Results showed that the group with ARMS had a significantly higher interpersonal sensitivity on average (112.5) as compared to healthy individuals (91.8). Results show significant difference in both of the groups (t = –5.049; P < .0001) indicating that interpersonal sensitivity in people with ARMS was relatively high compared to those who were not at risk.

Conclusion

This study suggests that being ‘hypersensitive’ to interpersonal interactions is a psychological feature of the potentially prodromal phase of psychosis. Addressing difficulties in interpersonal relationships and offering early psychotherapeutic interventions can be beneficial, not only in averting serious illness, but preventing loss to individual and national productivity.

The Bag-1 inhibitor, Thio-2, reverses an atypical 3D morphology driven by Bag-1L overexpression in a MCF-10A model of ductal carcinoma in situ

Mammary MCF-10A cells seeded on reconstituted basement membrane form spherical structures with a hollow central lumen, termed acini, which are a physiologically relevant model of mammary morphogenesis. Bcl-2-associated athanogene 1 (Bag-1) is a multifunctional protein overexpressed in breast cancer and ductal carcinoma in situ. When present in the nucleus Bag-1 is predictive of clinical outcome in breast cancer. Bag-1 exists as three main isoforms, which are produced by alternative translation initiation from a single mRNA. The long isoform of Bag-1, Bag-1L, contains a nuclear localisation sequence not present in the other isoforms. When present in the nucleus Bag-1L, but not the other Bag-1 isoforms, can interact with and modulate the activities of estrogen-, androgen- and vitamin D-receptors. Overexpression of Bag-1 mRNA in MCF-10A is known to produce acini with luminal filling reminiscent of ductal carcinoma in situ. As this mRNA predominantly overexpresses the short isoform of Bag-1, Bag-1S, we set out to examine whether the nuclear Bag-1L isoform is sufficient to drive premalignant change by developing a Bag-1L-overexpressing MCF-10A model. Two clones differentially overexpressing Bag-1L were grown in two-dimensional (2D) and three-dimensional (3D) cultures and compared with an established model of HER2-driven transformation. In 2D cultures, Bag-1L overexpression reduced proliferation but did not affect growth factor responsiveness or clonogenicity. Acini formed by Bag-1L-overexpressing cells exhibited reduced luminal clearing when compared with controls. An abnormal branching morphology was also observed which correlated with the level of Bag-1L overexpression, suggesting further malignant change. Treatment with Thio-2, a small-molecule inhibitor of Bag-1, reduced the level of branching. In summary, 3D cultures of MCF-10A mammary epithelial cells overexpressing Bag-1L demonstrate a premalignant phenotype with features of ductal carcinoma in situ. Using this model to test the small-molecule Bag-1 inhibitor, Thio-2, reveals its potential to reverse the atypical branched morphology of acini that characterizes this premalignant change.

Anatomically accurate hard priors for transrectal electrical impedance tomography (TREIT) of the prostate

Current prostate biopsy procedures entail sampling tissues at template-based locations that are not patient specific. Ultrasound (US)-coupled transrectal electrical impedance tomography (TREIT), featuring an endorectal US probe retrofitted with electrodes, has been developed for prostate imaging. This multi-modal imaging system aims to identify suspicious tumor regions based on their electrical properties and ultimately provide additional patient-specific locations where to take biopsy samples. Unfortunately, the open-domain geometry associated with TREIT results in a severely ill-posed problem due to the small number of measurements and unbounded imaging domain. Furthermore, reconstructing contrasts within the prostate volume is challenging because the conductivity differences between the prostate and surrounding tissues are much larger than the conductivity differences between benign and malignant tissues within the prostate. To help overcome these problems, anatomically accurate hard priors can be employed to limit estimation of the electrical property distribution to within the prostate volume; however, this requires the availability of structural information. Here, a method that extracts the prostate surface from US images and incorporates this surface into the image reconstruction algorithm has been developed to enable estimation of electrical parameters within the prostate volume. In this paper, the performance of this algorithm is evaluated against a more traditional EIT algorithm that does not use anatomically accurate structural information, in the context of numerical simulations and phantom experiments. The developed anatomically accurate hard-prior algorithm demonstrably identifies contrasts within the prostate volume while an algorithm that does not rely on anatomically accurate structural information is unable to localize these contrasts. While inclusions are identified in the correct locations, they are found to be smaller in size than the actual object due to the rapid decay in sensitivity at increasing distances from the probe surface. Despite this, identifying the size of the inclusion accurately may not be essential for biopsy guidance in a clinical setting; instead, knowledge of the general vicinity of a cancerous lesion may be sufficient for suggesting and guiding clinicians to extract additional biopsy cores.

Plasmapheresis in the treatment of hypertriglyceridemia-induced pancreatitis: A community hospital's experience

BACKGROUND

Hyperlipidemic pancreatitis is a potentially fatal complication of hypertriglyceridemia (HTG). The current mainstay of treatment for the hypertriglyceridemia associated with pancreatitis includes heparin, insulin and lipid lowering agents. Experiences with plasmapheresis are limited. Here, we report our experience using plasmapheresis in the treatment of four patients with acute severe HTG-induced pancreatitis.

METHODS

Four patients with acute severe HTG-induced pancreatitis due to severe primary hyperlipidemia exacerbated by secondary factors were studied. In addition to the standard treatment (insulin or heparin infusion), antibiotics and lipid lowering agents, two were treated within the first 48 hours, and two with early (<24 hours) plasmapheresis with 5% albumin.

RESULTS

All four patients had a significant improvement in their triglyceride levels using plasmapheresis with an average reduction in TG levels of 70.4% per treatment and 89.3% with the first treatment. However, there was no clear relation between the use of plasmapheresis and either improvement in APACHE II scores, length of stay in either the ICU or overall hospital length of stay or in the prevention of complications secondary to severe pancreatitis, including in the two patients who received plasmapheresis in the first 24 hours.

CONCLUSION

Our report showed that plasmapheresis was successful in lowering TG levels. However, in the absence of a comparison with standard treatment (heparin or insulin infusion and lipid lowering agents) the effect of plasmapheresis on lowering the morbidity and length of stay of patients with HTG-induced acute severe pancreatitis is uncertain and warrants further investigation into its efficacy.

Near patient blood ketone measurements and their utility in predicting diabetic ketoacidosis

AIM

To assess the utility of near patient blood ketone measurements in predicting diabetic ketoacidosis (DKA) among a group of hyperglycaemic unwell patients presenting to a hospital emergency department.

METHODS

Near patient blood beta-hydroxybutyrate (beta-OHB) testing has recently been introduced as a new tool in our hospital Accident and Emergency department (A&E) for patients with a finger-prick glucose of > 11 mmol/l. We reviewed the records of the first 50 patients to have a beta-OHB measurement to establish if they developed DKA or received treatment with intravenous insulin within 48 h of presentation. We then compared the diagnostic power of beta-OHB measurements with other clinical, physiological and biochemical markers of DKA.

RESULTS

Nine patients had DKA, eight had a compensated metabolic acidosis secondary to raised serum ketones, and 33 had no evidence of DKA during the following 48 h. The median (range) beta-OHB levels in each group were 6.0 (3.1-6.0) mmol/l, 3.4 (1.2-5.7) mmol/l, and 0.1 (0.0-1.2) mmol/l, respectively. A beta-OHB level of > or = 3.0 mmol/l had a sensitivity of 100% and specificity of 88% for DKA. All those with beta-OHB level > 3.0 mmol/l required treatment with intravenous insulin.

CONCLUSION

Measuring beta-OHB when a hyperglycaemic patient is identified could offer a simple method of identifying at an early stage those patients at highest risk of DKA (beta-OHB > 3.0 mmol/l), and redirecting the search for a diagnosis in others (beta-OHB < 1.0 mmol/l).

Coding errors: a comparative analysis of hospital and prospectively collected departmental data

OBJECTIVES

To assess the accuracy of a hospital coding database at a busy tertiary referral urological unit.

METHODS

Prospectively collected departmental coding data for all urological patients attending the Churchill Hospital, Oxford between 1 May 1999 and 30 April 2000 were compared with the coding data entered by hospital coding clerks on the Oxford Radcliffe NHS Trust database.

RESULTS

There were significant discrepancies between the number of patients on the hospital and the departmental database (639 vs 1109). There were gross procedural coding errors in 74 cases.

CONCLUSION

Hospital-coded data in this study were incomplete and inaccurate. This has important implications when considering the validity of hospital-trust databases when used as a source for medical research, clinical audit and as a representation of a consultants' clinical workload.
