Lipid clinic experience with bempedoic acid in three UK centres.

OBJECTIVE: Novel lipid-lowering therapies are being introduced. Few studies exist of the real-world effectiveness of adenosine-tri-phosphate citrate lyase inhibition with bempedoic acid. METHODS: This study audited bempedoic acid therapy in 216 consecutive patients from three hospital centres - a university hospital (n = 77) and two district general hospitals (n = 106 and 33). Cardiovascular disease (CVD) risk factors, prescription qualification criteria, efficacy and adverse effects were assessed. RESULTS: The population was aged 65.9 ± 11.0 years, 42% were male, 25% had type 2 diabetes, and 31% had familial hypercholesterolaemia. CVD was present in 19% and multibed vascular disease in 8%. Statin intolerance was reported in 92%. Bempedoic acid reduced total cholesterol by 1.58 ± 1.44 mmol/L (20%), LDL-C by 1.37 ± 1.31 mmol/L (27%), triglycerides by 0.22 mmol/L (2%) with an 0.06 mmol/L (1%) increase in HDL-C after 22 ± 9 months follow-up. An LDL-C <2.5 mmol/L was achieved in 40% and <2 mmol/L in 20%. Efficacy (r2 = .33) was predicted by baseline LDL-C (ß = .54; p <.001). No significant changes were seen in transaminases, creatinine, creatine kinase, urate or HbA1c. Treatment was discontinued by 33% of patients and occurred due to myalgia (43%), lack of efficacy (16%) and gastrointestinal adverse effects (15%). No cases of gout were observed. In a logistic regression only the number of previous drug classes not tolerated (ß = 1.60; p = .009) was a contributing factor to discontinuation. CONCLUSION: This audit suggests that bempedoic acid therapy is effective but that adverse effects and discontinuation are common. This suggests nocebo effects might be generalizable to all lipid-lowering drug therapies in susceptible individuals.

The Road towards Triple Agonists: Glucagon-Like Peptide 1, Glucose-Dependent Insulinotropic Polypeptide and Glucagon Receptor - An Update.

Obesity is the fifth leading risk factor for global deaths with numbers continuing to increase worldwide. In the last 20 years, the emergence of pharmacological treatments for obesity based on gastrointestinal hormones has transformed the therapeutic landscape. The successful development of glucagon-like peptide-1 (GLP-1) receptor agonists, followed by the synergistic combined effect of glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 receptor agonists achieved remarkable weight loss and glycemic control in those with the diseases of obesity and type 2 diabetes. The multiple cardiometabolic benefits include improving glycemic control, lipid profiles, blood pressure, inflammation, and hepatic steatosis. The 2023 phase 2 double-blind, randomized controlled trial evaluating a GLP-1/GIP/glucagon receptor triagonist (retatrutide) in patients with the disease of obesity reported 24.2% weight loss at 48 weeks with 12 mg retatrutide. This review evaluates the current available evidence for GLP-1 receptor agonists, dual GLP-1/GIP receptor co-agonists with a focus on GLP-1/GIP/glucagon receptor triagonists and discusses the potential future benefits and research directions.

Medical training in acute specialties: the acute care common stem training pathway.

In 2007, the acute care common stem pathway changed the delivery of acute specialty training. Acute care common stem is the core training programme for all emergency medicine trainees, 46% of anaesthetic trainees and a cohort of acute medicine trainees with more than 630 places nationally, the third highest of any core training programme. In their first 2 years of core training (CT1-2), trainees rotate through 6-month rotations in emergency medicine, acute medicine, anaesthetics and intensive care to gain core competencies in the assessment and management of acutely unwell patients, before completing 1 year (CT3) in their parent specialty. Acute care common stem trainees benefit from undertaking rotations in allied acute specialties, which is invaluable when treating complex and comorbid patients in an ageing population. Acute care common stem gives trainees core skills in management of acutely unwell patients, which can be built upon in higher specialty training.

Exploring UK medical school differences: the MedDifs study of selection, teaching, student and F1 perceptions, postgraduate outcomes and fitness to practise.

BACKGROUND: Medical schools differ, particularly in their teaching, but it is unclear whether such differences matter, although influential claims are often made. The Medical School Differences (MedDifs) study brings together a wide range of measures of UK medical schools, including postgraduate performance, fitness to practise issues, specialty choice, preparedness, satisfaction, teaching styles, entry criteria and institutional factors. METHOD: Aggregated data were collected for 50 measures across 29 UK medical schools. Data include institutional history (e.g. rate of production of hospital and GP specialists in the past), curricular influences (e.g. PBL schools, spend per student, staff-student ratio), selection measures (e.g. entry grades), teaching and assessment (e.g. traditional vs PBL, specialty teaching, self-regulated learning), student satisfaction, Foundation selection scores, Foundation satisfaction, postgraduate examination performance and fitness to practise (postgraduate progression, GMC sanctions). Six specialties (General Practice, Psychiatry, Anaesthetics, Obstetrics and Gynaecology, Internal Medicine, Surgery) were examined in more detail. RESULTS: Medical school differences are stable across time (median alpha = 0.835). The 50 measures were highly correlated, 395 (32.2%) of 1225 correlations being significant with p < 0.05, and 201 (16.4%) reached a Tukey-adjusted criterion of p < 0.0025. Problem-based learning (PBL) schools differ on many measures, including lower performance on postgraduate assessments. While these are in part explained by lower entry grades, a surprising finding is that schools such as PBL schools which reported greater student satisfaction with feedback also showed lower performance at postgraduate examinations. More medical school teaching of psychiatry, surgery and anaesthetics did not result in more specialist trainees. Schools that taught more general practice did have more graduates entering GP training, but those graduates performed less well in MRCGP examinations, the negative correlation resulting from numbers of GP trainees and exam outcomes being affected both by non-traditional teaching and by greater historical production of GPs. Postgraduate exam outcomes were also higher in schools with more self-regulated learning, but lower in larger medical schools. A path model for 29 measures found a complex causal nexus, most measures causing or being caused by other measures. Postgraduate exam performance was influenced by earlier attainment, at entry to Foundation and entry to medical school (the so-called academic backbone), and by self-regulated learning. Foundation measures of satisfaction, including preparedness, had no subsequent influence on outcomes. Fitness to practise issues were more frequent in schools producing more male graduates and more GPs. CONCLUSIONS: Medical schools differ in large numbers of ways that are causally interconnected. Differences between schools in postgraduate examination performance, training problems and GMC sanctions have important implications for the quality of patient care and patient safety.

The Analysis of Teaching of Medical Schools (AToMS) survey: an analysis of 47,258 timetabled teaching events in 25 UK medical schools relating to timing, duration, teaching formats, teaching content, and problem-based learning.

BACKGROUND: What subjects UK medical schools teach, what ways they teach subjects, and how much they teach those subjects is unclear. Whether teaching differences matter is a separate, important question. This study provides a detailed picture of timetabled undergraduate teaching activity at 25 UK medical schools, particularly in relation to problem-based learning (PBL). METHOD: The Analysis of Teaching of Medical Schools (AToMS) survey used detailed timetables provided by 25 schools with standard 5-year courses. Timetabled teaching events were coded in terms of course year, duration, teaching format, and teaching content. Ten schools used PBL. Teaching times from timetables were validated against two other studies that had assessed GP teaching and lecture, seminar, and tutorial times. RESULTS: A total of 47,258 timetabled teaching events in the academic year 2014/2015 were analysed, including SSCs (student-selected components) and elective studies. A typical UK medical student receives 3960 timetabled hours of teaching during their 5-year course. There was a clear difference between the initial 2 years which mostly contained basic medical science content and the later 3 years which mostly consisted of clinical teaching, although some clinical teaching occurs in the first 2 years. Medical schools differed in duration, format, and content of teaching. Two main factors underlay most of the variation between schools, Traditional vs PBL teaching and Structured vs Unstructured teaching. A curriculum map comparing medical schools was constructed using those factors. PBL schools differed on a number of measures, having more PBL teaching time, fewer lectures, more GP teaching, less surgery, less formal teaching of basic science, and more sessions with unspecified content. DISCUSSION: UK medical schools differ in both format and content of teaching. PBL and non-PBL schools clearly differ, albeit with substantial variation within groups, and overlap in the middle. The important question of whether differences in teaching matter in terms of outcomes is analysed in a companion study (MedDifs) which examines how teaching differences relate to university infrastructure, entry requirements, student perceptions, and outcomes in Foundation Programme and postgraduate training.

Internet Use for Social Interaction by People with Psychosis: A Systematic Review.

People with psychosis (PWP) have difficulties in establishing and maintaining social connections. An earlier systematic review on the use of online social networking (OSN) in psychosis found only 11 studies published before January 2014, but with promising findings. These studies showed no difference in OSN use between PWP and general population. Given the limited number of articles found and the rapid advances in OSN, we carried out an update review to assess evidence on how PWP use OSN. Several electronic databases were searched for the literature published between January 2014 and May 2018. Data from included studies were narratively synthesized. Thirteen additional studies examined the use of OSN in PWP in 2014-2018. Updated evidence confirms that PWP seem to use OSN at least as much as the general population, although only when not acutely unwell. PWP who are younger and have higher education level are more likely to use OSN. There was no evidence of worsening psychological symptoms due to OSN. Some studies showed patient-reported concerns about negative experiences and the inability to identify online social contacts. The use of OSN by PWP is a subject of increasing interest with a rapidly developing evidence base. The frequent use of OSN by PWP and the absence of evidence of symptom worsening are encouraging findings. This would justify the inclusion of OSN among the strategies to reduce social isolation in psychosis. Research methodologies should be improved by developing standardized measures to assess use and associated risks.

Traumatic cataract in patient with anterior megalophthalmos: Case report.

RATIONALE: Megalophthalmos anterior is a rare, bilateral, nonprogressive, hereditary, congenital disorder, characterized by the enlargement of all anterior segment structures of the eye, with megalocornea, iris atrophy, and zonular abnormalities commonly found. Usually almost asymptomatic in young patients, with most complaints concerning blurred vision due to the common corneal astigmatism, it might in time lead to several complications including premature cataract formation and pigmentary glaucoma. PATIENT CONCERNS: This review presents the case of a 47-year old patient referred to our clinic for traumatic cataract surgery, with striking bilateral megalocornea, somehow overlooked during previous ophthalmic examinations in his local outpatient clinic. DIAGNOSIS: We noticed markedly enlarged corneas and deepened anterior chambers of his both eyes, accompanied by intumescent, white cataract of the right eye, and incipient cortical cataract of the left eye. Best corrected visual acuity (BCVA) was counting fingers in the right eye and 20/25 in the left eye. Additional examination revealed multiple abnormalities of the anterior segment, leading to the diagnosis of anterior megalophthalmos. It is astounding the patient remained undiagnosed during previous examinations, with his megalocornea and remarkably deep anterior chamber so apparent. INTERVENTIONS AND OUTCOMES: We performed standard phacoemulsification procedure, with 3 piece posterior chamber intraocular lens (PCIOL) implantation into the lens capsule. The surgery was uneventful, with postoperative BCVA of 20/20 in the right eye, and no dislocation of the lens in 9-month observation period. LESSONS: Complicated cataract in patients with anterior megalophthalmos can be successfully treated with standard phacoemulsification procedure followed by the bag PCIOL implantation.Care needs to be taken during cataract surgery in these patients, as zonular abnormalities and lens enlargement are common, resulting in increased rate of intra- and postoperative complications. As patients with anterior megalophthalmos require a more careful follow-up.

Which peer teaching methods do medical students prefer?

BACKGROUND: The beneficial effects of peer teaching in medical education have been well-described in the literature. However, it is unclear whether students prefer to be taught by peers in small or large group settings. This study's aim was to identify differences in medical students' preferences and perceptions of small-group versus large-group peer teaching. METHODS: Questionnaires were administered to medical students in Year 3 and Year 4 (first 2 years of clinical training) at one institution in the United Kingdom to identify their experiences and perceptions of small-and large-group peer teaching. For this study, small-group peer teaching was defined as a tutorial, or similar, taught by peer tutor to a group of 5 students or less. Large-group peer teaching was defined as a lecture, or similar, taught by peer tutors to a group of more than 20 students. RESULTS: Seventy-three students (81% response rate) completed the questionnaires (54% males; median age of 23). Nearly 55% of respondents reported prior exposure to small-group peer teaching but a larger proportion of respondents (86%) had previously attended large-group peer teaching. Of all valid responses, 49% did not have a preference of peer teaching method while 47% preferred small-group peer teaching. The majority of Year 3 students preferred small-group peer teaching to no preference (62.5% vs 37.5%, Fisher's exact test; P = 0.035) whereas most Year 4 students did not report a particular preference. Likert-scale responses showed that the majority of students held negative perceptions about large-group peer teaching, in comparison with small-group peer teaching, with respect to (1) interactivity, (2) a comfortable environment to ask questions, and (3) feedback received. DISCUSSION: Most respondents in this study did not report a preference for small-versus large-group settings when taught by peers. More Year 3 respondents were likely to prefer small-group peer teaching as opposed to Year 4 respondents.

Different Impacts of Luminosity on Contrast Vision in Eyes with Transparent Optic Media and with Cataract Simulation.

OBJECTIVE: To evaluate the effect of luminous intensity on contrast vision under different ocular conditions. MATERIALS AND METHODS: Ninety eyes of 45 persons were included in this study as follows: 30 healthy eyes, 30 eyes with cataract simulation (using translucent glasses), and 30 myopic eyes. Contrast sensitivity was examined using 5 spatial frequencies (1.5, 3.0, 6.0, 12.0, and 18.0 cycles per degree) of sine wave contrast test optotypes for 4 light intensities (34, 68, 154, and 240 cd/m2). RESULTS: The mean linear contrast sensitivities averaged over the frequencies for each of the 4 light intensities were: healthy eyes: 59 ± 11, 72 ± 16, 79 ± 23, and 80 ± 19; myopic eyes: 52 ± 13, 67 ± 15, 73 ± 21, and 75 ± 18, and cataract simulation eyes: 15 ± 7, 21 ± 8.6, 28.7 ± 13, and 28.6 ± 13, respectively. The linear contrast sensitivities averaged over the light intensities for each of the 5 spatial frequencies were: healthy eyes: 78, 87, 117, 59, and 21; myopic eyes: 65, 84, 109, 54, and 29, and cataract simulation eyes: 37, 41, 28, 8, and 2. CONCLUSIONS: The light intensity level had a positive effect on the contrast sensitivity of the examined eyes, except for eyes with cataract simulation, where even the maximum light intensity did not improve the contrast vision. This indicates that patients with cataracts require increased contrast of text rather than brighter illumination to improve the quality of their vision.

Management of renin-angiotensin system blockade in patients with chronic kidney disease under specialist care. Retrospective cross-sectional study.

BACKGROUND: Reduction of blood pressure and proteinuria by blockade of the renin-angiotensin-aldosterone system (RAAS) has been the cornerstone of renoprotective intervention for patients with chronic kidney disease (CKD) for many years. AIMS: The aims were to check the use of angiotensin converting enzyme inhibitors (ACEIs) and/or angiotensin II receptor blockers (ARBs) in CKD patients. METHODS: This was a retrospective, cross-sectional study analysing data from medical records of patients who received specialist care in 1996, 2001, 2006, 2011 in the Outpatient Unit. RESULTS: The numbers of CKD subjects included in the four independent surveys were as follows: 190, 490, 1799, 1696. The usage of RAAS blocking agents overall increased significantly in subsequent years as follows: 25, 49, 63, 74%. Patients with proteinuria and cardiovascular complications and/or diabetes were receiving RAAS blocking agents more commonly than others. The use of ACEI and/ or ARB in stage 4-5 CKD increased in subsequent years. In 2011 dual RAAS blockade was used in 10% CKD patients overall and 19% patients presented proteinuria. CONCLUSION: The use of RAAS blocking agents were increasing in CKD patients under specialist care between 1996-2011. The quality of the management was gradually improved.

Treatment of hypertension in chronic kidney disease patients under specialized care: one-center cross-sectional analyses.

AIM: The study analyzed hypertension management and control rates among non-dialysis, non-transplanted hypertensive chronic kidney disease (CKD) patients under specialized care in Gdansk nephrology center in 1996-2011. PATIENTS AND METHODS: It was a retrospective, cross-sectional study analyzing data from medical records of 190, 490, 1799 and 1696 subjects with CKD, who received outpatient care in 1996, 2001, 2006 and 2011, and were included in four independent surveys, respectively. RESULTS: The average number of antihypertensive drugs per patient increased significantly (p < 0.01) as follows 1.74 ± 0.9 (1996), 2.08 ± 1.01 (2011), 2.5 ± 1.19 (2006) and 2.65 ± 1.18 (2011). The percentage of patients receiving diuretics, beta-blockers and drugs inhibiting renin-angiotensin-aldosterone increased significantly in subsequent years, while a frequency of therapy with calcium channel blockers decreased (p < 0.001). 16%, 30%, 42% and 54% of subjects had causal BP values < 140/90 mmHg (p < 0.001). When specific thresholds for CKD patients according to JNC recommendations were used, the control rate was worse but also showed significant improvement in the second, third and final surveys, i.e. 9%, 12%, 14% and 24% (p < 0.001). The subgroup analysis revealed that a better control rate was observed in following groups: < 65 years old; I-II stage of CKD; primary glomerulonephritis; without cardiovascular complications or diabetes. CONCLUSION: The study may show an improvement in the effectiveness of antihypertensive treatment in CKD patients under specialized care in Gdansk Nephrology Centre in 1996-2011.

Comparative description of males of two species of Achtheres von Nordmann, 1832 (Copepoda: Siphonostomatoida: Lernaeopodidae) infecting zander and European perch.

Achtheres percarum von Nordmann, 1832 and Achtheres sandrae Gadd, 1901 (Lernaeopodidae) are common parasitic copepods infecting fishes in Eurasia. The former is specific to perch, Perca fluviatilis L., while the latter, to zander, Sander lucioperca (L.). Until recently these copepods have been regarded a single species. The present study was intended to analyse details of male morphology and provide their complete descriptions with differential diagnosis. Males of A. percarum and A. sandrae were collected from perch and zander at Lake Dabie (north-western Poland). The males of A. sandrae are larger than those of A. percarum. They also differ in proportions of the first antenna, mandibular denticulation, structure of the first maxilla, and the armament of caudal ramus. The reported differences in male morphology constitute a conclusive confirmation of the separate identity of the two species.
