Imaging Insights Suggesting a Sinister Cause of a Breast Mass in Adolescents: A Case of Rhabdomyosarcoma in a Teenager.

Background: Sarcomas of the breast are exceedingly rare, accounting for less than 1% of malignant breast tumors, with primary rhabdomyosarcomas being even rarer. Due to the scarcity of reported cases, the imaging characteristics of breast rhabdomyosarcoma are not well-defined, making diagnosis challenging, especially in adolescents. Case description: We present the case of a 17-year-old female diagnosed with embryonal rhabdomyosarcoma following a comprehensive workup for right breast masses. Initial imaging showed no distant metastasis, and the patient underwent a right mastectomy followed by adjuvant chemoradiotherapy. A few months post-treatment, she developed recurrent nodules in the chest wall. Further investigation confirmed the recurrence of embryonal rhabdomyosarcoma. Conclusions: This case underscores the importance of considering primary rhabdomyosarcoma as a differential diagnosis in adolescent breast lesions. Given its rare occurrence and potential imaging overlap with more common tumors like cystosarcoma phyllodes, awareness and careful evaluation are critical for accurate diagnosis and timely management. LEARNING POINTS: Critical imaging insights: The report provides valuable imaging characteristics that can help differentiate rhabdomyosarcoma from more common breast tumors like fibroadenoma and cystosarcoma phyllodes, resulting in more accurate and timely diagnosis.

Excess long-term risk of adverse outcomes in heart failure patients with high and low levels of NT-proBNP: A 7-year follow-up study (NorthStar Trial).

Background: This study investigated excess risk in patients with heart failure with reduced left ventricular ejection fraction (HFrEF) with or without elevated levels of NT-proBNP (N-terminal pro-brain natriuretic peptide). Methods: Patients with HFrEF from the NorthStar cohort (n = 1120) were matched on age, sex, and presence of AF (atrial fibrillation/flutter) to five controls without HFrEF from The Danish National Patient Registries. Patients were compared with controls before and after stratification according to baseline NT-proBNP levels, with cutoffs defined as

Facial Venous Tumour Thrombus from Submandibular Gland Mucoepidermoid Carcinoma: An Atypical Tumour Spread in Head and Neck Cancer.

Background: Tumour thrombus of the facial vein is an exceedingly rare complication arising from mucoepidermoid carcinoma of the salivary glands. Early detection is pivotal for appropriate management, as delays can lead to metastatic disease, worsening the prognosis. Case description: We present a case involving a 76-year-old male with a history of mucoepidermoid carcinoma of the right submandibular gland, previously treated with surgical resection and radiotherapy. The patient, a long-term worker in a rubber factory, presented with a painless, firm swelling in the right cheek, persisting for three months. Contrast-enhanced computed tomography (CECT) showed distended facial vein with enhancing thrombus confirmed by sonographic correlation demonstrating intralesional vascularity. Cannon ball pulmonary nodules were also noted. Radiological findings led to a core biopsy, confirming tumor thrombosis of the facial vein due to mucoepidermoid carcinoma. However, the patient declined a biopsy of the pulmonary nodules, and has been referred to oncology for further management. Conclusions: This case highlights the critical importance of considering venous tumour thrombus in patients with previous salivary gland malignancies presenting with new or persistent facial swellings. It emphasises the role of advanced imaging techniques in the early identification of this rare entity. Additionally, it stresses the need for healthcare providers to engage in thorough discussions with patients about the potential consequences of forgoing recommended treatments, reinforcing the need for vigilance in monitoring such patients. LEARNING POINTS: Tumours of head and neck may cause thrombosis of veins by direct invasion resulting in a tumour thrombus, or indirectly by exerting a mass effect and vein compression.These can be distinguished by contrast-enhanced computed tomography (CECT) or magnetic resonance imaging (MRI).Doppler ultrasound may show patchy neovascularisation in a tumour thrombus, which would be absent if thrombosis was caused by compression.

Radiofrequency as a method of localizing impalpable breast lesions.

BACKGROUND: The incidence of early stage breast cancer has risen as a result of increased detection of non-palpable tumors through the implementation of screening programs and greater public awareness. Performing breast-conserving surgery can be challenging due to the need for accurate localization of non-palpable breast lesions, particularly given the logistical difficulties associated with wire localization. After implementing a new technique for localizing non-palpable breast lesions (LOCalizerTM Radiofrequency identification TAG-Hologic®), a radiofrequency identification tag localization device manufactured by Hologic, Inc. in Marlborough, MA, was launched in 2017, our objective was to investigate its impact on surgical outcomes, whether there was an increase in re-excision rates for positive margins and whether the attainment of clear margins was dependent on the exact positioning of the RFID device. METHOD: A single-center single-arm interventional study, data were gathered both in a forward-looking manner for 1 year (prospectively) and by looking back at past records for 1 year (retrospectively) for a total period of two years. Individuals who were diagnosed with non-palpable breast lesions, as confirmed by histological analysis, or invasive breast cancer and who were scheduled to undergo breast-conserving surgery were eligible for inclusion in the study. The RFID (Radiofrequency Identification) method was used to localize the lesions prior to surgery. Either with a mammogram or ultrasound scan position of the Tag was recorded, including the distance of the lesion from the center of the lesion and the lesion depth from the skin in millimeters. The rate of re-excision was documented and examined in relation to the parameters mentioned above. RESULTS: Two hundred and twenty RFID Tags were inserted in two hundred and seventeen (three patient had bilateral tags insertion), patients aged between 30 and 85 had a localizer Tag inserted between Oct 2020 and Oct 2022. Three patients had non-palpable breast lesions in both breasts. Fourteen were inserted under stereotactic guidance and two hundred and six under ultrasound guidance. Ten patients subsequently had wire insertion also due to Tag position. Of 210 procedures, RFIF Tags within the lesion was seen in hundred and sixty patients (76.19 %). An additional 50 procedures were performed using the RFID Tag system, which were not directly related to the lesion but were deemed appropriate to proceed with. Out of a total of 220 procedures, positive margins were observed in 38 cases (17.27 %). Among these cases, eleven (28.94 %) involved the use of the RFID Tag system, not within the lesion but adjacent to it (within 15 mm surrounding the lesion). CONCLUSION: RFID is a good alternative to wire localization of non-palpable breast lesions. Re-excision rates are higher in patients with Tag outside the lesion compared to those with Tag within the lesion.

Temporal trends in infection-related hospitalizations among patients with heart failure: A Danish nationwide study from 1997 to 2017.

BACKGROUND: Despite improved survival, hospitalization is still common among patients with heart failure (HF). OBJECTIVE: This study aimed to examine temporal trends in infection-related hospitalization among HF patients and compare it to temporal trends in the risk of HF hospitalization and death. METHODS: Using Danish nationwide registers, we included all patients aged 18 to 100 years, with HF diagnosed between January 1, 1997 and December 31, 2017, resulting in a total population of 147.737 patients. The outcomes of interest were primarily infection-related hospitalization and HF hospitalization and secondarily all-cause mortality. The Aalen Johansen's estimator was used to estimate 5-year absolute risks for the primary outcomes. Additionally, cox analysis was used for adjusted analyses. RESULTS: The population had a median age of 74 [64, 82] years and 57.6 % were males. Patients with HF had a higher risk of infection over time 16.4 % (95% CI 16.0-16.8) in 1997 to 2001 vs 24.5% (95% CI 24.0-24.9) in 2012 to 2017. In contrast, they had a lower risk of HF hospitalization 26.5% (95% CI 26.1-27.0) in 1997 to 2001 vs 23.2% (95% CI 22.8-23.7) in 2012 to 2017. The risk of infection stratified by infection type showed similar trends for all infection types and marked the risk of pneumonia infection as the most significant in all subintervals. CONCLUSION: In the period from 1997 to 2017, we observed patients with HF had an increased risk of infection-related hospitalization, driven by pneumonia infections. In contrast, the risk of HF hospitalization decreased over time.

Temporal trends in mortality, heart failure hospitalisation, and stroke in heart failure patients with and without atrial fibrillation: a nationwide study from 1997-2018 on 152,059 patients.

AIMS: We aimed to investigate temporal trends in all-cause mortality, heart failure (HF) hospitalisation, and stroke from 1997 to 2018 in patients diagnosed with both HF and atrial fibrillation (AF). METHODS AND RESULTS: From Danish nationwide registers, we identified 152 059 patients with new-onset HF between 1997 and 2018. Patients were grouped according to year of new-onset HF and AF-status: Prevalent AF (n = 34 734), New-onset AF (n = 12 691), and No AF (n = 104 634). Median age decreased from 76 to 73 years between 1997 and 2018. The proportion of patients with prevalent or new-onset AF increased from 24.7% (n = 9256) to 35.8% (n = 14 970). Five-year risk of all-cause mortality went from 69.1% (CI: 67.9%-70.2%) to 51.3% (CI: 49.9%-52.7%), 62.3% (CI: 60.5%-64.4%) to 43.0% (CI: 40.5%-45.5%), and 61.9% (CI: 61.3%-62.4%) to 36.7% (CI: 35.9%-37.6%) for the Prevalent AF, New-onset AF and No AF-group, respectively. Minimal changes were observed in the risk of HF-hospitalisation. Five-year stroke risk decreased from 8.5% (CI: 7.8%-9.1%) to 5.0% (CI: 4.4%-5.5%) for the prevalent AF group, 8.2% (CI: 7.2%-9.2%) to 4.6% (CI: 3.7%-5.5%) for new-onset AF, and 6.3% (CI: 6.1%-6.6%) to 4.9% (CI: 4.6%-5.3%) for the No AF group. Simultaneously, anticoagulant therapy increased for patients with prevalent (from 42.7% to 93.1%) and new-onset AF (from 41.9% to 92.5%). CONCLUSION: From 1997 to 2018, we observed an increase in patients with HF and co-existing AF. Mortality decreased for all patients, regardless of AF-status. Anticoagulation therapy increased, and stroke risk for patients with AF was reduced to a similar level as patients without AF in 2013-2018.

Chest Wall Synovial Sarcoma: A Unique Encounter at the Breast Base.

Synovial sarcomas most commonly arise in the para-articular locations of the extremities, such as the upper limbs, thigh, knee, ankle, and foot. Thoracic synovial sarcomas are a rare entity that can arise in the chest wall, pleura, lung, heart, or mediastinum. We present a case of a 23-year-old female with a complaint of swelling of the left breast. Examination demonstrated an enlarged left breast and a hard-fixed swelling without overlying skin changes or nipple retraction. Ultrasound showed a well-defined, solid-appearing lesion deep in the left breast parenchyma, which was adherent to the underlying left chest wall musculature and seemed to be displacing the breast parenchyma anteriorly. Contrast-enhanced computed tomography (CECT) and magnetic resonance imaging (MRI) confirmed the lesion centered at the left pectoralis major and minor muscles, confirming the chest wall's origin. Histopathology findings favored monophasic synovial sarcoma.

Lost Connection: A Case Report of Interrupted Pituitary Stalk Syndrome.

Pituitary stalk interruption syndrome is a triad of thin (<1 mm) or complete absence of the pituitary stalk with either an aplastic or ectopic posterior lobe of the pituitary gland and a hypoplastic or absent anterior lobe of the pituitary. Patients present with growth retardation, short height, seizures, intellectual disability, and absence of sexual maturation at the expected time. Here, we presented a case of a 12-year-old male with stunted growth. Upon examination, there was reduced height, more than 3 standard deviations below the average for his chronological age. Laboratory results showed reduced levels of growth hormone and thyrotropin. Dual-energy X-ray absorptiometry revealed osteoporosis, while an X-ray of the wrist for bone age corresponded to seven years. MRI imaging confirmed the classical triad of findings for pituitary stalk interruption syndrome. Consequently, the patient was referred back to the endocrinology clinic for further management.

Age-specific mortality trends in heart failure over 25 years: a retrospective Danish nationwide cohort study.

BACKGROUND: Despite advances in heart failure care reducing mortality in clinical trials, it remains unclear whether real-life cohorts have had similar improvements in life expectancy across the age spectrum. We aimed to investigate how mortality trends changed in patients with heart failure over the past 25 years, stratified by age groups. METHODS: Using Danish nationwide registries, we identified patients with new-onset heart failure aged 18-95 years. The 5-year all-cause mortality risk and the absolute risk difference of mortality between patients with heart failure and age-matched and sex-matched heart failure-free controls were assessed using Kaplan-Meier estimates and multivariable Cox regression models. Mortality trends were analysed across five calendar periods (1996-2000, 2001-05, 2006-10, 2011-15, and 2016-20) and three age groups (<65 years, 65-79 years, and ≥80 years). FINDINGS: 194 997 patients with heart failure were included. Mortality significantly decreased from 1996-2000 (66% [95% CI 65·5-66·4]) to 2016-20 (43% [42·1-43·4]), with similar results shown in all age groups (<65 years: 35% [33·9-36·1] to 15% [14·6-16·3]; 65-79 years: 64% [63·1-64·5] to 39% [37·6-39·6]; and ≥80 years: 84% [83·1-84·3] to 73% [71·7-73·9]). Adjusted mortality rates supported these associations. The absolute risk difference declined notably in younger age groups (<65 years: 29·9% [28·8-31·0] to 12·7% [12·0-13·4] and 65-79 years: 41·1% [40·3-41·9] to 25·1% [24·4-25·8]), remaining relatively stable in those aged 80 years or older (30·6% [29·9-31·3] to 28% [27·2-28·8]). INTERPRETATION: Over 25 years, there has been a consistent decrease in mortality among patients with heart failure across age groups, albeit less prominently in patients aged 80 years or older. Further insight is needed to identify effective strategies for improving disease burden in older patients with heart failure. FUNDING: None.

Temporal Trends in the Initiation of Dialysis Among Patients With Heart Failure With or Without Diabetes: A Nationwide Study From 2002 to 2016.

BACKGROUND: The incidence and distribution of acute and chronic dialysis among patients with heart failure (HF), stratified by diabetes, remain uncertain. We hypothesized that with improved survival and rising comorbidities, the demand for dialysis would increase over time. METHODS AND RESULTS: Patients with incident HF, aged 18 to 100 years, between 2002 and 2016, were identified using Danish nationwide registers. Primary outcomes included acute and chronic dialysis initiation, HF-related hospitalization, and all-cause mortality. These outcomes were assessed in 2002 to 2006, 2007 to 2011, and 2012 to 2016, stratified by diabetes. We calculated incidence rates (IRs) per 1000 person-years and hazard ratios (HR) using multivariable Cox regression. Of 115 533 patients with HF, 2734 patients received acute dialysis and 1193 patients received chronic dialysis. The IR was 8.0 per 1000 and 3.5 per 1000 person-years for acute and chronic dialysis, respectively. Acute dialysis rates increased significantly among patients with diabetes over time, while no significant changes occurred in those without diabetes, chronic dialysis, HF-related hospitalization, or overall mortality. Diabetes was associated with significantly higher HRs of acute and chronic dialysis, respectively, compared with patients without diabetes (HR, 2.07 [95% CI, 1.80-2.39] and 2.93 [95% CI, 2.40-3.58] in 2002 to 2006; HR, 2.45 [95% CI, 2.14-2.80] and 2.86 [95% CI, 2.32-3.52] in 2007 to 2011; and 2.69 [95% CI, 2.33-3.10] and 3.30 [95% CI, 2.69-4.06] in 2012 to 2016). CONCLUSIONS: The IR of acute and chronic dialysis remained low compared with HF-related hospitalizations and mortality. Acute dialysis rates increased significantly over time, contrasting no significant trends in other outcomes. Diabetes exhibited over 2-fold increased rates of the outcomes. These findings emphasize the importance of continued monitoring and renal care in patients with HF, especially with diabetes, to optimize outcomes and prevent adverse events.

Relapse after cessation of weekly tocilizumab for giant cell arteritis: a multicentre service evaluation in England.

OBJECTIVES: The National Health Service in England funds 12 months of weekly subcutaneous tocilizumab (qwTCZ) for patients with relapsing or refractory giant cell arteritis (GCA). During the COVID-19 pandemic, some patients were allowed longer treatment. We sought to describe what happened to patients after cessation of qwTCZ. METHODS: Multicentre service evaluation of relapse after stopping qwTCZ for GCA. The log-rank test was used to identify significant differences in time to relapse. RESULTS: 336 GCA patients were analysed from 40 centres, treated with qwTCZ for a median (interquartile range, IQR) of 12 (12-17) months. At time of stopping qwTCZ, median (IQR) prednisolone dose was 2 (0-5) mg/day. By 6, 12 and 24 months after stopping qwTCZ, 21.4%, 35.4% and 48.6% respectively had relapsed, requiring an increase in prednisolone dose to a median (IQR) of 20 (10-40) mg/day. 33.6% of relapsers had a major relapse as defined by EULAR. Time to relapse was shorter in those that had previously also relapsed during qwTCZ treatment (P = 0.0017); in those not in remission at qwTCZ cessation (P = 0.0036); and in those with large vessel involvement on imaging (P = 0.0296). Age ≥65, gender, GCA-related sight loss, qwTCZ treatment duration, TCZ taper, prednisolone dosing, and conventional synthetic DMARD use were not associated with time to relapse. CONCLUSION: Up to half our patients with GCA relapsed after stopping qwTCZ, often requiring a substantial increase in prednisolone dose. One third of relapsers had a major relapse. Extended use of TCZ or repeat treatment for relapse should be considered for these patients.

Can Artificial Intelligence Beat Humans in Detecting Breast Malignancy on Mammograms?

BACKGROUND: The study was aimed at identifying how useful Computer-Aided Detection (CAD) could be in reducing false-negative reporting in mammography and early detection of breast cancer at an early stage as the best protection is early detection. MATERIALS AND METHODS: This retrospective study was conducted in a tertiary care setup of Atomic Energy Cancer Hospital, Nuclear Medicine, Oncology and Radiotherapy Institute (AECH-NORI), where 33 patients with suspicious findings on mammography and subsequent biopsy-proven malignancy were included. The findings of mammography including the lesion type, breast parenchymal density, and sensitivity of CAD detection, as well as the final biopsy results, were recorded. A second group of 40 normal screening mammograms was also included who had no symptoms, had Breast Imaging-Reporting and Data System category I(BI-RADS I) mammograms, and had no pathology identified on correlative sonomammography as well. RESULTS: A total of 35 masses, 11 pleomorphic clusters of microcalcification, five clustered foci of macrocalcification, and nine lesions with pleomorphic clusters of microcalcification and two with pleomorphic clusters of microcalcification only were included. The CAD system was able to identify 26 masses (74%), eight lesions with pleomorphic clusters of microcalcification (72%), five foci of macrocalcification (100%), six lesions with pleomorphic clusters of microcalcification (66%), and two pleomorphic clusters of microcalcification without formed mass (100%). The overall sensitivity of the CAD system was 75.8%. CAD was able to identify 13 out of 16 masses with invasive ductal carcinoma (81.3%), eight out of nine lesions proven as invasive ductal carcinoma with ductal carcinoma in situ (DCIS) (88.9%), two out of five masses with invasive lobular carcinoma (40%), four out of four masses with invasive mammary carcinoma (100%), and zero out of one lesion identified as medullary carcinoma (0%). There was 100% detection for pleomorphic clusters of microcalcification without formed mass with CAD marking two out of two mammograms. CONCLUSION: CAD performed better with combined lesions, accurately marked pleomorphic clusters of microcalcification, and identified small lesions in predominant fibrofatty parenchymal density but was not reliable in dense breast, areas of asymmetric increased density, summation artifacts, edematous breast parenchyma, and retroareolar lesions. It also performed poorly with ill-defined lesions of invasive lobular carcinoma. Human intelligence hence beats CAD for the diagnosis of breast malignancy in mammograms as per our experience.

Ferrous Illusion: A Unique Case of Welding Fume Particles Appearing as Metallic Artifacts in MRI.

A rare cause of metallic artifacts over the scalp on magnetic resonance imaging (MRI) is welding fume particles that contain paramagnetic iron oxide particles. These introduce distortion of the magnetic field homogeneity and result in susceptibility artifacts. They may erroneously be reported as a pathology such as calcified lesions; therefore, awareness among radiologists is required. We report a case of a 52-year-old male, an industrial inspector by profession, who presented to the neurology clinic with headaches for which an MRI of the brain without contrast was advised. There was no brain parenchymal signal abnormality; however, numerous small rounded altered signal foci were identified along the scalp, especially in the vertex region, which returned central hypointense and marginal hyperintense signal on all sequences. The imaging signals were suspicious for calcified scalp lesions, and the patient was recalled for clinical examination, which was unremarkable for cutaneous or subcutaneous abnormality on the scalp or elsewhere over the body. A detailed history was taken retrospectively, revealing that the patient had walked through a room where welding was being done before presenting for an MRI exam, without taking a shower. The various altered signal foci over the scalp on MRI based on their shape were hence identified as welding fume particles. These were fine enough not to be visible by the naked eye but determined by the MRI machine because of their magnetic susceptibility artifact. We aim to increase radiologists' awareness of such artifacts that may be seen in patients with occupational exposure to these particles to avoid misdiagnosis of other pathologies.

Initiation of SGLT2 inhibitors and GLP-1 receptor agonists according to level of frailty in people with type 2 diabetes and cardiovascular disease in Denmark: a cross-sectional, nationwide study.

BACKGROUND: Whether frailty influences the initiation of two cardioprotective diabetes drug therapies (ie, SGLT2 inhibitors and GLP-1 receptor agonists) in people with type 2 diabetes and cardiovascular disease is unknown. We aimed to assess rates of initiation of SGLT2 inhibitors and GLP-1 receptor agonists according to frailty in people with type 2 diabetes and cardiovascular disease. METHODS: For this cross-sectional, nationwide study, all people with type 2 diabetes and cardiovascular disease in Denmark between Jan 1, 2015, and Dec 31, 2021, from six Danish health-data registers were identified. People younger than 40 years, with end-stage renal disease, with registered contraindications to SGLT2 inhibitors or GLP-1 receptor agonists, or with previous use of either drug therapy were excluded. The Hospital Frailty Risk Score was used to categorise people as either non-frail, moderately frail, or severely frail. Cox proportional hazards models were used to analyse the association between frailty and initiation of an SGLT2 inhibitor or a GLP-1 receptor agonist. FINDINGS: Of 119 390 people with type 2 diabetes and cardiovascular disease, 103 790 were included. Median follow-up time was 4·5 years (IQR 2·7-6·1) and median age across the three frailty groups was 71 years (64-79). 65 959 (63·6%) of 103 790 people were male and 37 831 (36·5%) were female. At index date, 66 910 (64·5%) people were non-frail, 29 250 (28·2%) were moderately frail, and 7630 (7·4%) were severely frail. Frailty was associated with a significantly lower probability of initiating therapy with an SGLT2 inhibitor or a GLP-1 receptor agonist than in people who were non-frail (moderately frail hazard ratio 0·91, 95% CI 0·88-0·94, p<0·0001; severely frail 0·75, 0·70-0·80, p<0·0001). This association persisted after adjustment for age, sex, socioeconomic status, year of inclusion, duration of type 2 diabetes, duration of cardiovascular disease, polypharmacy, and comorbidity. INTERPRETATION: In people with type 2 diabetes and cardiovascular disease in Denmark, frailty was associated with a significantly lower probability of SGLT2-inhibitor or GLP-1 receptor-agonist initiation, despite their benefits. Formulating clear and updated guidelines on the use of SGLT2 inhibitors and GLP-1 receptor agonists in people who are frail with type 2 diabetes and cardiovascular disease should be a priority.

Initiation of Medical Therapy for Heart Failure Patients According to Kidney Function: A Danish Nationwide Study.

Background: Use of medical therapies for heart failure (HF) patients with moderate kidney dysfunction is low. We hypothesized that lack of initiation of HF therapy reflects the clinicians' reluctance in very elderly and frail patients more than kidney dysfunction itself. Methods: HF patients were identified from nationwide registers between 2014 and 2021. Information was obtained on eGFR, frailty status, and prescription of HF therapy. Patients were divided into three groups: normal kidney function (eGFR ≥ 60); moderate kidney dysfunction (GFR between 30 and 59); and severe kidney dysfunction (GFR < 30). Multivariate Cox models were used to study the association of eGFR, age, and frailty with use of HF therapy. Results: Of the 42,320 HF patients included those with lower eGFR were significantly older and frailer (median age 74.3 years and 37.8% frail). The crude initiation rate of all three drug classes decreased with decreasing eGFR in a stepwise fashion. After adjusting for age and frailty status, initiation of MRA decreased with decreasing kidney function (moderate kidney function HR 0.80(95% CI 0.77-0.84) and severe kidney function HR 0.24(0.21-0.27)). After adjusting for age and frailty status, initiation of RAS inhibitor and BB was not significantly lower for moderate kidney dysfunction (HR 0.97(0.93-1.02), and HR 1.06(0.97-1.16, respectively)). Initiation of RAS inhibitor was significantly lower for patients with severe kidney dysfunction, HR 0.45(0.41-0.50), but not for BB initiation HR 1.09(1.05-1.14). Conclusion: In a real-world HF cohort, patients with moderate and severe kidney dysfunction were associated with reduced use of MRA irrespective of age and frailty. Reduced use of RASi was associated with severe kidney dysfunction, whereas for patients with moderate kidney dysfunction, reduced use was mainly driven by aging and frailty. Reduced use of BB seemed to be primarily explained by aging and frailty.

Duodenal ulcer perforation and its consequences.

Duodenal ulcer perforation, a frequent surgical emergency, needs simple closure with indirect Graham's Omentopexy which is effective with excellent results in majority of cases despite patients' late presentation. The objective of the study was to determine the frequency of postoperative complications of perforated duodenal ulcer, conducted in the Surgery Department, Jinnah Postgraduate Medical Centre, Karachi, from March 20, 2018 to September 20, 2018. The study was a descriptive case series of 108 patients of both genders with perforated duodenal ulcer > 1 week old with ASA score I & II. Patients with trauma and comorbidities were excluded. The patients underwent laparotomy and peritoneal toilet, and after noting the site of perforation indirect Graham's Omentopexy was performed. Complications like duodenal fistula, peritonitis, and paralytic ileus, and patient's death within 10 days of surgery were noted. Age ranged from 18 to 50 years with mean age of 35.027±5.13 years, mean weight 71.120±12.77 kg, mean height 1.541 ±0.09 metres, mean BMI 29.975±4.99 kg/m2, and the mean duration of complaint was 4.194±1.30 weeks. Male predominance in 75 (69.4%) patients. Duodenal fistula was seen in 10 (9.3%) patients, peritonitis 12 (11.1%), paralytic ileus 14 (13%) and mortality was in 11 (10.2%) patients.

Discontinuation and reinitiation of SGLT-2 inhibitors and GLP-1R agonists in patients with type 2 diabetes: a nationwide study from 2013 to 2021.

Background: Small observational studies have observed poor persistency to sodium-glucose cotransporter-2 inhibitors (SGLT2-i) and glucacon-like-peptide-1-receptor agonists (GLP1-RA), contrary to what has been reported in clinical trials. Therefore, we investigated the risk of discontinuing SGLT2-is and GLP1-RAs in patients with type 2 diabetes (T2D) in a nationwide population. Methods: From Danish nationwide registers, all first-time users of SGLT2-is and GLP1-RAs from 2013 to 2021 were identified. Adherence over the first year of therapy, the five-year risk of discontinuing therapy for the first time and the subsequent one-year probability of reinitiating therapy, was assessed. The Aalen-Johansen estimator was used to account for censoring and competing risks and multivariable Cox regression models were used to identify covariates associated with discontinuation. Findings: A total of 77,745 first-time users of SGLT2-is (64% male, median age 64 [interquartile range 56-72]) and 56,037 first-time users of GLP1-RAs (56% male, median age 61 [53-70]) were included. The absolute five-year risk of discontinuing therapy was 56% (95% CI: 55-57) and 45% (45-46) for SGLT2-i- and GLP1-RA users, respectively, with a significantly decreased risk over the period studied. The subsequent one-year probability of reinitiating therapy was 24% (95% CI: 24-25) for initial SGLT2-i users and 26% (25-27) for GLP1-RA users. Interpretation: Approximately half of the users of SGLT2-is and GLP1-RAs discontinued therapy within five years, respectively. However, a large proportion of these patients reinitiated therapy during the following year. Further insight into the reasons for discontinuation and initiatives to reduce the time to reinitiation in eligible patients are warranted.

Biosynthesizing Cassia fistula Extract-Mediated Silver Nanoparticles for MCF-7 Cell Lines Anti-Cancer Assay.

The unique consequence of green synthesis is that the mediator plant is able to release chemicals that are efficacious as reducing as well as stabilizing agents. In this work, the fruit pulp and leaf essences of Cassia fistula have been used to manufacture silver nanoparticles through the green synthesis technique. The sculpturing of nanoparticles was accomplished by utilizing the reduction phenomenon that ensued due to the reaction between plant essences and the precursor solution. These biosynthesized silver nanoparticles were examined, where we used scanning electron microscopy, UV-vis spectroscopy, and X-ray diffraction techniques as means to analyze the structure, optical properties, and crystalline behavior, respectively. The absorption spectra for fruit and leaf extracts obtained from the UV-vis analyses peaked at 401 and 397 nm, and these peaks imply the appearance of optical energy gaps of 2.12 and 2.58 eV, accompanying spherical shapes of particles with diameters in the ranges of 12-20 and 50-80 nm, respectively. These silver nanoparticles together with the adopted green technique have a vast array of applications, specifically in the biomedical realm. In particular, they are being used to treat several diseases and are manifested as strong anti-tumor agents to medicate MCF-7 breast cancer cell lines in order to minimize the cell growth rate depending on their concentrations.

Heart Failure Following Anti-Inflammatory Medications in Patients With Type 2 Diabetes Mellitus.

BACKGROUND: Fluid retention and endothelial dysfunction have been related to use of nonsteroidal anti-inflammatory drugs (NSAIDs), and type 2 diabetes mellitus (T2DM) has been linked to both a decline in kidney function and subclinical cardiomyopathy. OBJECTIVES: The authors hypothesized that short-term use of NSAIDs could lead to subsequent development of incident heart failure (HF) in patients with T2DM. METHODS: Using nationwide Danish registers, we identified patients diagnosed with T2DM during 1998 to 2021 and included patients without previous HF, rheumatic disease, or use of NSAIDs 120 days before diagnosis. Associations between NSAIDs and first-time HF hospitalization were investigated using a case-crossover design with 28-day exposure windows, and ORs with 95% CIs were reported. RESULTS: Included were 331,189 patients with T2DM: 44.2% female, median age of 62 years (IQR: 52-71 years); 23,308 patients were hospitalized with HF during follow-up, and 16% of patients claimed at least 1 NSAID prescription within 1 year. Short-term use of NSAIDs was associated with increased risk of HF hospitalization (OR: 1.43; 95% CI: 1.27-1.63), most notably in subgroups with age ≥80 years (OR: 1.78; 95% CI: 1.39-2.28), elevated hemoglobin (Hb) A1c levels treated with 0 to 1 antidiabetic drug (OR: 1.68; 95% CI: 1.00-2.88), and without previous use of NSAIDs (OR: 2.71; 95% CI: 1.78-4.23). CONCLUSIONS: NSAIDs were widely used and were associated with an increased risk of first-time HF hospitalization in patients with T2DM. Patients with advanced age, elevated HbA1c levels, and new users of NSAID seemed more susceptible. These findings could guide physicians prescribing NSAIDs.

Dual biologic therapy for the treatment of rheumatic diseases and asthma: a case series.

Objective: Combination biological therapies are being considered increasingly for patients with multiple co-morbidities requiring biologics. There are limited data available on this approach, and concerns remain about the possible risk of adverse events, particularly infection. Methods: We present three patients on dual biologics for rheumatic disease and asthma. The biologic combinations used were etanercept and mepolizumab, infliximab and omalizumab, and etanercept and omalizumab. The time on combination biologic therapies ranged from 24 to 36 months. Patients were monitored for any serious adverse events. Results: All three patients were able to tolerate combined biologic therapies, with no serious adverse events. All three patients gained improvement in their rheumatic and asthma disease control, with reduction in disease activity scores and reduction in steroid usage. Conclusion: The decision to start dual biologic therapy should be considered carefully, on a case-by-case basis. The number of patients who are on combination biological therapy is small, and data are sparse. Real-world data are needed to examine the long-term benefits and risks of different forms of combination biologic therapies.
