Background: Effective diabetic retinopathy screening (DRS) programmes are important in preventing vision impairment and blindness caused by diabetes. This study focuses on identifying the factors affecting attendance or non-adherence to DRS among children and young adults with diabetes mellitus (DM) in Bangladesh.

Methods: A mixed-methods approach was used, which included patients diagnosed with DM aged 12-26 years from Bangladesh who were registered at BIRDEM Women and Children hospital in Dhaka. Data collection occurred between July 2019 and July 2020, mainly through telephone and email due to restrictions imposed by the COVID-19 pandemic. Statistical analyses, including chi-squared tests, t-tests, and logistic regression, were used to assess the demographic and clinical factors influencing attendance at DRS.

Results: The study reported a high 88% attendance rate for DRS among children and young adults in Bangladesh. However, some barriers to attendance were identified. Children under 15 years of age showed a higher tendency to attend their last DRS appointment when compared to older age participants (16-26 years), P < 0.05. Male participants demonstrated a lower likelihood of attending their DRS appointments than females (OR 0.29, CI: 0.17 to 0.50), P < 0.001. Additionally, participants with higher HbA1c levels (mean 9.1%, IQR 2.5) attended their last DRS appointment compared to those with lower levels (mean 8.0%) (p < 0.05). The primary barriers leading to missed DRS appointments were distance to the hospital (15, 31.9%), financial limitations (19, 40.4%), and busy schedules (14, 29.8%).

Conclusions: Compliance with DRS was high in this setting especially among younger patients, females, and those with higher HbA1c levels, highlighting the effectiveness of current DRS initiatives in Bangladesh. Addressing barriers such as cost, service accessibility and transportation could improve attendance rates further, and strategies such as flexible scheduling, transport subsidies, telemedicine, and use of artificial intelligence may help overcome these challenges.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing health concern and the risk of its development is connected with the increasing prevalence of metabolic syndrome (MetS) which occurs as a result of some complex obesity-induced metabolic changes. It is a common chronic liver disease characterized by excessive fat accumulation in the liver, the tendency to progress to more severe forms, and a corresponding increase in morbidity and mortality. Thus, effectively addressing the rising burden of the disease requires a thorough understanding of its complex interrelationship with obesity and MetS.

Main body: MASLD results from complex interactions involving obesity, insulin resistance, and dyslipidaemia, leading to hepatic lipid accumulation, and is influenced by several genetic and environmental factors such as diet and gut microbiota dysbiosis. It has extensive metabolic and non-metabolic implications, including links to MetS components like hyperglycaemia, hypertension, and dyslipidaemia, and progresses to significant liver damage and other extra-hepatic risks like cardiovascular disease and certain cancers. Diagnosis often relies on imaging and histology, with non-invasive methods preferred over liver biopsies. Emerging biomarkers and OMIC technologies offer improved diagnostic capabilities but face practical challenges. Advancements in artificial intelligence (AI), lifestyle interventions, and pharmacological treatments show promise, with future efforts focusing on precision medicine and novel diagnostic tools to improve patient outcome.

Conclusion: Understanding the pathogenic mechanisms underlying the development of MASLD within the context of metabolic syndrome (MetS) is essential for identifying potential therapeutic targets. Advancements in non-invasive diagnostic tools and novel pharmacological treatments, hold promise for improving the management of MASLD. Future research should focus on precision medicine and innovative therapies to effectively address the disease and its consequences.

Background: Monacolin-K, the active component of red yeast rice (RYR), reduces cholesterol by inhibiting HMG-CoA reductase. Following safety concerns, the European Food Safety Authority (EFSA) recommended limiting Monacolin-K intake to less than 3 mg/day due to adverse effects at higher doses.

Case presentation: A study comparing Armolipid Plus^® and LopiGLIK^® found LopiGLIK^® more effective in lowering LDL cholesterol, possibly due to slightly higher dosages of Berberine and Monacolin-K. Despite reducing Monacolin-K content to 2.99 mg following EFSA guidelines, LopiGLIK^® maintained its cholesterol-lowering efficacy.

Conclusions: Taken together, our results indicate that other ingredients, such as Morus alba, may contribute to LopiGLIK^®'s enhanced effectiveness, challenging the notion that minor differences in Monacolin-K dosage account for the observed efficacy.

Background: Propylthiouracil is an antithyroid medication that is associated with ANCA positivity, often in the absence of clinically overt vasculitis. Propylthiouracil-induced ANCA-associated vasculitis (AAV) is characterized by multiple antigenicity and presents similarly to other forms of drug-induced vasculitis.

Case presentation: We report a case of a 49-year-old woman who developed propylthiouracil-induced AAV after 31 years of intermittent therapy. The patient presented with progressive respiratory and generalized symptoms. She was diagnosed with propylthiouracil-induced AAV with alveolar hemorrhage based on detection of ANCA and anti-MPO antibodies, exclusion of primary vasculitis, and symptom resolution following propylthiouracil withdrawal. The patient was treated with intravenous methylprednisolone, followed by oral prednisolone. Her symptoms resolved, and her laboratory and radiological tests improved within one week.

Conclusions: Research linking the duration of propylthiouracil use to the development of vasculitis is restricted by multiple methodological limitations. Maintaining a high index of clinical suspicion is a more reliable approach to detecting propylthiouracil-induced AAV than regular laboratory monitoring, given that patients with Graves' disease may show ANCA positivity in the absence of medication use. Therefore, clinicians should remain vigilant for the varied presentations of propylthiouracil-induced AAV. Moreover, further research is recommended to investigate the possible link between the duration of PTU use and the onset of clinically overt vasculitis.

Background: Type 2 diabetes mellitus (T2DM) is a multifaceted metabolic disorder. Over the past decade, the potential role of Growth Hormone (GH) and Insulin-like Growth Factor-1 (IGF-1) in the pathogenesis and progression of T2DM has garnered scientific interest. These hormones, while interrelated, exert differential effects on glucose homeostasis; GH elevates blood glucose levels, whereas IGF-1 sustains insulin secretion and augments insulin sensitivity.

Objective: The study aimed to investigate the impact of insulin resistance and glycaemic control on IGF-1 levels and to assess other risk factors influencing IGF-1 in T2DM.

Methods: A cross-sectional study was conducted at the National Diabetes Centre, Baghdad, Iraq, from May 2020 to May 2021. Sixty patients with T2DM were evaluated for fasting plasma glucose (FPG), GH, IGF-1, HbA1c, HOMA-IR, HOMA-B, and anthropometric measures following a comprehensive history and physical examination, focusing on any variables that could influence their metabolic profile. Patients with Type 1 diabetes mellitus, thyroid disease, pituitary disease, chronic kidney disease, hepatic disease, and pregnancy were excluded from the study.

Results: Patients with poorly controlled diabetes (HbA1c > 8) exhibited significantly elevated IGF-1 levels compared to those with HbA1c < 8 (166 vs. 134, P = 0.016). The mean IGF-1 was significantly lower in patients with insulin resistance (IR) compared to those without IR (143 vs. 192, P = 0.001), with a significant negative correlation with Body Mass Index (BMI) and a significant positive correlation with HbA1c and Quantitative Insulin Sensitivity Index (QUICKI). Elevated IGF-1 levels were observed with increasing age, duration of T2DM, higher HbA1c, higher QUICKI, and lower BMI. No significant difference was found in IGF-1 values with regards to HOMA-B, fasting insulin, and waist-hip ratio.

Conclusion: Patients with poorly controlled T2DM exhibit higher IGF-1 levels, while those with obesity and high insulin resistance demonstrate lower IGF-1 levels. Further prospective studies are warranted to evaluate the potential of using IGF-1 to reduce insulin resistance and improve metabolic and glycaemic measures in individuals with T2DM and obesity or insulin resistance.

Background: We present one of only seven reported cases of a catecholamine-secreting adrenal neuroblastoma in an adult. The case is used as a platform to discuss key biochemical, genomic and imaging considerations that are central to the successful, targeted management of catecholamine-secreting adrenal tumours.

Case presentation: A 63-year-old male was urgently reviewed at a tertiary hospital endocrinology outpatient clinic for a 12 cm right-sided adrenal incidentaloma. Plasma normetanephrine and 3-methoxytyramine levels were approximately 10 times the upper limit of normal at 9272 pmol/L (< 900) and 1023 pmol/L (< 110), respectively. The adrenal mass appeared to be inseparable from the liver on imaging, and thus was suspected to be an invasive malignant phaeochromocytoma. FDG positron emission tomography (PET)/CT demonstrated moderate to intense metabolic activity within the right adrenal mass. [68 Ga]Ga-DOTATATE (Ga-TATE) PET-CT demonstrated patchy, heterogenous somatostatin receptor (SSTR) expression in the adrenal lesion, at most Krenning 3 (intensity above liver). The patient underwent a right adrenalectomy and segment 6/7 liver resection. Histopathology revealed a 130 mm diameter neuroblastoma of the differentiating subtype with a low Mitosis-Karyorrhexis Index. There was lymphovascular invasion and tumour focally present at the resection margin, but no tumour in one periadrenal lymph node, and no tumour invasion in the adherent liver. Immunohistochemistry revealed ALK positivity (+ 3) and wild type ATRX. At nine months following adrenalectomy, the plasma normetanephrine level has reduced to 991 pmol/L (< 900). Post-operative GaTate PET/CT shows no definite abnormal SSTR-expressing lesions in the surgical bed or elsewhere. The patient has completed adjuvant radiotherapy and is a candidate for ALK-targeted therapy if required for recurrence in the future.

Conclusions: Neuroblastomas may be misdiagnosed as phaeochromocytomas given the ability to secrete catecholamines and similarities in radiological appearance. Differentiating neuroblastomas from phaeochromocytomas and paragangliomas (PPGL) is critical, but clinically difficult. Genomics are central for management; diagnosing ALK-positive neuroblastoma triggers consideration of ALK-targeted therapy, which is not relevant for PPGL. A critical eye is required for the accurate diagnosis and management of malignant adrenal incidentalomas.

Background: Osteomyelitis of the diabetic foot is a common and challenging complication affecting patients with diabetic foot ulcers and infections. The complexity of these infections lies in their polymicrobial nature, high rates of persistence and recurrence. This study examined the microbiological profile of diabetic foot osteomyelitis from a teaching hospital in Northwest England and their resistance patterns to understand its impact on infection persistence and to direct effective treatment.

Methods: A retrospective review of 105 patients who underwent surgical management for diabetic foot osteomyelitis between 2019 and 2024. We analysed three consecutive culture samples for each patient to assess for the microbiological profile and resistance patterns of these infections and to monitor infection recurrence and persistence rates.

Results: A total of 105 patients were identified. Infection eradication was noted in 42% of the cohort, infection persistence in 18%, and late infection recurrence in 40%. Polymicrobial growth was evident in 72% of our study sample. Gram-positive bacteria made up the majority of the bacterial isolates in all 3 culture samples, 74.81% in sample 1, 69.31% in sample 2, and 55.1% in sample 3. Staphylococcus aureus was the most prevalent gram-positive bacteria, at 52.38% in sample 1, 36.19% in sample 2, and 18.09% in sample 3, followed by Haemolytic Streptococcus, Enterococcus and Corynebacterium. The frequently identified gram-negative bacteria were Pseudomonas in sample 1 (7.61%), E. coli and Proteus in sample 2 (5,71%), Pseudomonas and Proteus in sample 3 (2.85%). Gram-positive bacteria were resistant to penicillin and macrolides with resistance of staphylococcus aureus to clarithromycin identified among all 3 culture samples. Gram-negative bacteria were most resistant to amoxicillin. Staphylococcus aureus was responsible for infection persistence in most of our cohort (12/19) 63.15%. Among those patients, Staphylococcus was resistant to clarithromycin in 6 of the cases. The 5-year mortality rate for our study sample was 32.38%.

Conclusion: This study highlights the prevalence of polymicrobial growth and multi-drug resistant pathogens in the scope of diabetic foot osteomyelitis. It highlights the predominance of Staphylococcus aureus and its resistant strains among patients affected by diabetic foot osteomyelitis in Greater Manchester.

Background: Diabetes mellitus (DM) is one of the most prevalent chronic diseases worldwide. Despite the existence of national strategies to prevent potential complications, DM-related morbidities and mortality continue to rise in Ethiopia. Although studies have been conducted regarding dietary practices among DM patients in the country, there is a lack of in-depth understanding of the situation.

Objective: To assess dietary practices and associated factors among adult DM patients at academic tertiary-level hospitals in central Ethiopia in 2024.

Methods: A concurrent mixed-methods study was conducted from January 01 to 30, 2024, involving 420 adult DM patients. Participants were selected using a simple random sampling technique for the quantitative study. A purposive sampling technique was used to select sixteen participants for qualitative analysis. For the quantitative study, a self-administered structured questionnaire was used to collect data, and in-depth interviews were conducted for the qualitative part. Multivariate binary logistic regressions were used to assess the explanatory variables associated with dietary practice. A thematic analysis was performed for qualitative data.

Result: Of 420 eligible participants, 406 (96.7%) participated in the study. The overall proportion of good dietary practices among participants was 172 (42.4%). Being female, residing in urban areas, having a family history of DM, and having good dietary knowledge were significantly associated with better dietary practices. From the qualitative analysis, two themes emerged "Living as before and not adhering to diabetic dietary recommendations" and "Barriers to adherence to effective eating practices."

Conclusions and recommendations: Less than half of adult DM patients had good dietary practices. Sex, geographic location, family history of DM, and level of knowledge of diabetic diet were associated with dietary practice. Intervention programs on awareness creation and training to improve the dietary practice by stakeholders were recommended.

Introduction: Sarcopenia is defined by low measures of muscle quantity, quality and reduced physical performance. It is associated with higher levels of frailty. Individuals with diabetes mellitus (DM) undergo sarcopenia at an accelerated rate resulting in structural changes potentially culminating in limb loss.

Aims: To review the evidence on methods of detecting and measuring sarcopenic changes on magnetic resonance imaging (MRI) in the foot in patients with diabetes.

Methods: A literature review was conducted in accordance with PRISMA guidelines. We searched Embase and Medline (via Ovid), CINAHL (via Ebsco Host), Web of Science and Scopus as well as the grey literature. The MeSH terms "sarcopenia" AND "diabetes mellitus" AND "magnetic resonance imaging" were employed in the primary search string.

Results: 874 studies were identified. 404 articles were excluded in the title and abstract screening. 33 studies were assessed for eligibility after abstract and title screening was completed by two reviewers. 7 studies evaluating sarcopenia in the foot were included in the final review.

Conclusion: Sarcopenic changes are evident on MRI of the foot in patients with diabetes and is profound in patients with diabetic neuropathy. The general extent and severity of sarcopenia seems to correlate with clinical scores to assess neuropathy and is implicated in the development of diabetic foot disease.

Background: Constipation, which affects 16% of adults worldwide, is a chronic health problem characterized by unsatisfactory frequency of bowel movements, causing pain, bloating or incomplete bowel movements. The study aims to assess the magnitude of chronic constipation and associated factors among T₂DM patients attending the endocrinology outpatient clinic at Hiwot Fana Comprehensive Specialized University Hospital from January 1 to May 30, 2023.

Methods: Hospital-based cross-sectional study design was carried out to assess the magnitude and associated factors of chronic constipation among T₂DM patients at Hiwot Fana Comprehensive Specialized University Hospital. Using a single population formula 300 T₂DM patients were enrolled in this study. The data was analyzed by using the Epi-Data 4.6 and SPSS version 25. Descriptive, bivariate, multivariate, and logistic regression were used. P < 0.05 was used to declare association.

Results: 300 T2DM patients participated in this survey. Of these 137 (45.7%) were male and 163 (54.3%) were female and the mean age was 58.57 ± 11.09 SD years, the range from 35 to 85 years. The prevalence of constipation was 73 (24.3%) (95% CI: 0.196-0.296). Education status above high school (AOR: 0.151.95% CI: 0.032-0.718), less than 7 h of sleep per day (AOR: 12.39.95% CI: 2.712-56.69), frequent depression (AOR: 6, 84, 95% CI: 2.639-17.743), parents with constipation (AOR: 6.843.95% CI: 2.639-17.743), daily water intake < 1300 ml (AOR: 4.760.95% CI: 1.146-19.773), TAG levels below 150 mg/dl (AOR: 0.050, 95% CI: 0.015-0.166), HbAlc between 6 and 7% (AOR: 0.013.95% CI: 0.001-0.132) ,HbAlc between 7.1 and 8% (AOR: 0.006, 95% CI: 0.001-0.067), and LDL levels were significantly associated with chronic constipation in T2DM patients.

Conclusions: The prevalence of chronic constipation was considerable in T2DM patients. Education level above high school, less than 7 h of sleep per day, frequent depression, parents with constipation, daily water intake < 1300 ml, TAG and HbAlc play a significant role in the development of chronic constipation in T2DM patients. T2DM patients can reduce the extent of constipation by treating the above problem in a timely and timely manner.
