3% vs 24.3%, p = 0.19, and 25.9% vs 23.5%, p = 0.51). Multivariate regression analyses confirmed the positive association of ROSC with the TM alert system (odds ratio1.49, 95% confidence interval 1.02‑2.19, p = 0.04).

ATM alert system seems to improve the chain of survival; because TM responders reached patients early, AEDs were attached more often and more OHCA patients achieved ROSC. However, the introduction of aTM alert system was not associated with improved 3‑month or 1‑year survival in aregion with above-average survival rates.

We describe the case of a male patient who presented with severe hypercalcemia and a left-sided palpable parathyroid mass. Over the course of the next 18 years, the patient underwent neck exploration surgery on multiple occasions due to recurrent primary hyperparathyroidism and refractory hypercalcemia, complicated by nephrolithiasis and impairment of renal function, while bone mineral density was preserved. Histological findings and the natural course of the disease were consistent with parathyromatosis. Medical interventions with oral bisphosphonates or high-dose cinacalcet failed to control the patient's hypercalcemia. The combination of monthly denosumab and cinacalcet was, however, successful in maintaining the patient's serum calcium in the normal/upper-normal range over a 36-month period with no significant side effects. This is the first report of off-label denosumab use in combination with cinacalcet in the long-term management of parathyromatosis-related refractory hypercalcemia.Neoplastic cells acquire the ability to proliferate endlessly by maintaining telomeres via telomerase, or alternative lengthening of telomeres (ALT). The role of telomere maintenance in pituitary neuroendocrine tumors (PitNETs) has yet to be thoroughly investigated. We analyzed surgical samples of 24 adult recurrent PitNETs (including onset and relapses for 14 of them) and 12 pediatric primary PitNETs. The presence of ALT was assessed using telomere-specific fluorescence in situ hybridization, methylation of telomerase reverse transcriptase promoter (TERTp) by methylation-specific PCR, and ATRX expression by immunohistochemistry. Among the adult recurrent PitNETs, we identified 3/24 (12.5%) ALT-positive cases. ALT was present from the onset and maintained in subsequent relapses, suggesting that this mechanism occurs early in tumorigenesis and is stable during progression. ATRX loss was only seen in one ALT-positive case. Noteworthy, ALT was observed in 3 out of 5 aggressive PitNETs, including two aggressive corticotroph tumors, eventually leading to patient's death. ALT-negative tumors (87.5%) were classified according to their low (29.2%), medium (50%), and high (8.3%) telomere fluorescence intensity, with no significant differences emerging in their molecular, clinical, or pathological characteristics. TERTp methylation was found in 6/24 cases (25%), with a total concordance in methylation status between onset and recurrences, suggesting that this mechanism remains stable throughout disease progression. TERTp methylation did not influence telomere length. In the pediatric cohort of PitNETs, TERTp methylation was also observed in 4/12 cases (33.3%), but no case of ALT activation was observed. In conclusion, ALT is triggered at onset and maintained during tumor progression in a subset of adult PitNETs, suggesting that it could be used for clinical purposes, as a potential predictor of aggressive behavior.Previous studies have reported a relationship between postural orthostatic tachycardia syndrome (POTS) and positivity for serum autoantibodies against G-protein-coupled receptors (GPCRs). However, the role of these autoantibodies in POTS is unclear. The present retrospective study analyzed the autoimmune etiology of POTS in 24 patients using a head-up tilt test to assess for any correlation between the clinical features of POTS and serum levels of autoantibodies against diverse GPCRs. In total, ten assessment items, including autonomic function tests, were analyzed. Of these, persistent, gastrointestinal symptoms and disease severity showed a significant association with the serum level of anti-muscarinic acetylcholine receptor (mAChRs) antibodies (gastrointestinal symptoms, M1, M2, M5; disease severity, M1, M3, M4, M5) [P less then 0.05]), while no significant association was found between the clinical features and autoantibodies against adrenergic receptors (α1, α2, β1, β2), angiotensin receptor 1, or endothelin receptor A. The patients were further divided into two groups based on the presence or absence of persistent gastrointestinal symptoms and then were characterized by the ten assessment items and neuropsychological tests, including the Wechsler Adult Intelligence Scale score and Self-Rating Depression Scale score. The results demonstrated a clear difference between the two groups in terms of disease severity, age at onset (older or younger than 20 years), and processing speed index (P less then 0.05), which were highly consistent with the association between these clinical features and the levels of serum anti-mAChR antibodies, particularly the anti-M5 receptor antibody. These findings suggested that anti-mAChR antibodies may play an important role in a subgroup of POTS patients with persistent gastrointestinal symptoms.

Various strategies are utilised to reduce blood loss and allogenic blood transfusion for posterior instrumented correction of Adolescent Idiopathic Scoliosis (AIS). The aim of this study was to evaluate post-operative blood transfusion requirements to determine whether routine cross matching of blood is essential.

This is a prospective case series of 84 patients who underwent posterior correction of AIS between September 2016 and March 2018. We reviewed demographic, operative, radiological data and transfusion requirements. Results of transfusion requirements in 44 patients who underwent Ponte osteotomies (FM = 368; mean age 14.8years) were compared with 40 patients (FM = 931; mean age 14.4years) who did not and provided the control group. A transfusion trigger of 80mg/dl with clinical caveats was utilised. Cross matching and procurement costs of allogenic blood/unit were ascertained.

Five patients required postoperative blood transfusion on days 2 or 3. Anaesthetic time (p = 0.0003) and preoperative Cobb angle (p = 0.0166) were significant variables between both groups and post-operative Hb (p = 0.0084) and number of levels fused (p = 0.0312) being significant in patients requiring transfusion. Unutilised units on the day of the operation incurred £30,030 (£380/patient or £154/unit) in operational costs.

Our audit demonstrates that transfusion on the day of the operation was not required. We recommend that routine crossmatching is not essential for primary posterior correction for AIS with blood conservation techniques. Blood grouping with availability of urgent blood is sufficient at the onset of operation. This has financial implications and cost savings.

III.Intravitreal therapy for diabetic macular edema can, in susceptible patients, increase intraocular pressure (IOP). As uncontrolled IOP can potentially be sight threatening, monitoring is an essential component of patient management. It can be challenging for retina specialists to ensure that monitoring is rigorous enough to detect and resolve any potential problems at the earliest opportunity without it also being overburdensome for patients who have the lowest risk of developing an IOP rise. We have developed dynamic algorithms that (1) tailor the frequency and extent of monitoring according to individual susceptibility and current IOP and (2) assist retina specialists in deciding when they should consider a referral to a glaucoma specialist. One algorithm is for patients with a relatively low susceptibility to developing an IOP rise (those whose baseline IOP is  25 mmHg or any rise from baseline is ≥ 10 mmHg. Thereafter, the algorithm guides on the frequency and extent of monitoring required in each of these groups and, if IOP rises or falls during treatment, patients may move up or down the risk groups accordingly. A different algorithm is provided for patients who are more susceptible to developing an IOP rise (those with a baseline IOP of ≥ 22 mmHg or a prior history of an IOP event). These patients need monitoring more closely so this algorithm has only medium- or high-risk classifications. These algorithms update the previous monitoring guidance by Goñi et al. (Goñi et al. in Ophthalmol Ther 547-61, 2016).This study aimed to explore gray matter volume (GMV) changes in patients undergoing hemodialysis and assess the clinical risk factors associated with GMV changes and the relationship between GMV changes and neuropsychologic test results. Eighty-eight hemodialysis patients and 76 healthy controls (HCs) were recruited in this study. Fifty patients underwent follow-up examinations (follow-up duration 1.75 ± 0.55 years), including magnetic resonance imaging, blood biochemical, and neuropsychologic testing. see more Changes in GMV between the patients and HCs were assessed. Longitudinal GMV changes were also explored in the patients. The clinical risk factors associated with longitudinal GMV changes and the correlations between longitudinal GMV changes and neuropsychologic test results were analyzed in the patients. Patients undergoing hemodialysis had diffusely decreased GMV compared with HCs (with age, sex, and total intracranial volume [TIV] as covariates, P less then 0.001, voxel-wise threshold false discovery rate [FDR] corrected). Compared with patients at baseline, regional decreased GMV were found in patients at follow-up (with age and TIV as covariates, P less then 0.05, voxel-wise threshold FDR corrected). Increased serum urea concentrations, parathyroid hormone levels, and hemodialysis duration were independent risk factors for decreased GMV in patients undergoing hemodialysis (all P less then 0.05, FDR corrected). Patients undergoing hemodialysis had lower mini-mental state examination (MMSE) (27[26, 29]) and Montreal cognitive assessment (MoCA) (22[19.5, 24.0]) scores than those of the HCs (30[29, 30] and 28[26.9, 29]) (all P less then 0.05). The MMSE scores of the patients at follow-up (26[25, 28.5]) were lower than those of patients at baseline (28[25, 29.5]) (P=0.02). The decreased left caudate volumes were positively correlated with reduced MMSE scores in hemodialysis patients (rs=0.437, P=0.033). Patients undergoing hemodialysis had noticeable GM atrophy over time, related to cognitive impairments.

The aim of this study was to investigate the clinical characteristics of patients with diffuse renal uptake (DRU) of 2-deoxy-2-[F-18]fluoro-D-glucose (FDG), with particular focus on renal function.

We retrospectively analyzed 40 patients who showed DRU on FDG PET/CT and the same number of matched controls. The clinical features, imaging parameters (the mean SUVmax of the kidneys and the kidney size), and laboratory data including renal function parameters (Cr, the serum creatinine level; estimated glomerular filtration ratio (eGFR); Cr-ratio, Cr divided by the baseline; max-Cr-ratio, the maximum serum creatinine level within 30days divided by the baseline) and C-reactive protein (CRP) were compared between the two groups. In the DRU group, follow-up FDG PET/CT scans were additionally evaluated to determine the presence of DRU.

No significant differences were observed in the clinical features except for antibiotic administration, Cr, and eGFR. Significantly more patients underwent antibiotic administration within 30days in the DRU group (p = 0.
