BACKGROUND:This study compared the outcomes between intensive and nonintensive insulin regimens and assessed the predictive factors for failing to achieve the glycated hemoglobin (A1C) goals in type-2-diabetes-mellitus (T2DM) patients requiring insulin therapy.METHODS:A single-center, retrospective assessment of the medical records of 125 T2DM patients undergoing intensive (46 patients) and nonintensive insulin therapy (79 patients) were conducted.RESULTS:No significant differences were found when the intensive and nonintensive insulin therapy groups were compared in terms of the percentage decreases of glucose and A1C levels. The mean A1C levels of the nonintensive and intensive groups declined from 11.15% and 11.30% to 7.97% and 8.06%, respectively.CONCLUSIONS:Both intensive and nonintensive insulin therapies improved the baseline glycemic parameters but being overweight or obese and/or being reluctant to dietary recommendations led to treatment failures regardless of the insulin regimen.
BACKGROUND Predicting a multiple gland disease (MGD) in primary hyperparathyroidism (pHPT) remains challenging. This study aimed to evaluate predictive factors for MGD. METHODS A retrospective chart review was performed of 1211 patients with histologically confirmed parathyroid adenoma or hyperplasia between 2007-2016. Localization diagnostics, laboratory parameters, and the weight of the resected parathyroid glands were evaluated concerning their predictive value of a multiple-gland disease. RESULTS A number of 1111 (91.7%) had a single-gland disease (SGD), and 100 (8.3%) a multiple-gland disease (MGD). US and MIBI scans were comparable for either negative or positive adenoma localization and suspected MGD. While the PTH level was similar, the calcium level was higher in SGD (2.8 mmol/L versus 2.76 mmol/L, P=0.034). MGD had a significantly lower gland weight (0.78 g versus 0.31 g; P<0.001). A gland weight of 0.418 grams was a predictive factor for MGD with a sensitivity of 72% and a specificity of 66%. CONCLUSIONS Only the weight of the resected parathyroid adenoma was meaningful in predicting MGD. A cut-off value of 0.418 g can differentiate SGD from MGD.
BACKGROUND:Twenty-twenty-five percent of patients with differentiated thyroid cancer (DTC) can have elevated thyroglobulin antibodies (TgAb). The study aimed to find any prognostic significance of elevated TgAb during follow-up. METHODS:Ten-year retrospective study from a tertiary center including 79 patients with raised TgAb after total/staged thyroidectomy for DTC. We identified patients with stable (7.6%), increasing (15%) and decreasing levels of TgAb (77.2%); groups 1, 2 and 3 respectively. During follow-up we analyzed TgAb in subcategories by TgAb trend (>50% rise, <50% rise, >50% decline, <50% decline, positive to negative/normalization, negative to positive and stable levels), gender, age, surgery, autoimmune disease, histology, RAI uptake, distant metastases, and recurrence. RESULTS:The incidence of raised TgAb levels was 33.2%, with female predominance. No connection was identified regarding other parameters. 11.4% had distant metastases. The highest mean maximum levels of TgAb was in group 2 (1918.75 IU/mL) and the lowest in group 3 (412.70 IU/mL). The recurrence rate changed significantly between the 3 groups: 50% in group 1, 75% in group 2, and 25% in group 3 (P=0.002). Recurrence rates decreased to 15% in the subcategory where TgAb became negative/normal from positive (P=0.0001). In patients with a negative to positive TgAb level trend or >50% rise, recurrence rates were 100% (P=0.041) and 70% (P=0.012) respectively. CONCLUSIONS:Patients with increasing TgAb levels during follow-up have a higher rate of recurrence, distinctly for those with negative to positive trend and >50% rise in TgAb. These patients need closer follow-up, and TgAb may be used as a dynamic follow-up marker.
Diabetes technology has proliferated extensively over the past few decades with vast ameliorations in glucose monitoring and in insulin delivery systems. From a treatment based on daily insulin injections, we have moved to increasingly advanced technologies. Despite such advancements which have allowed better glycemic control, decreased diabetes-related complications, and improved the quality of life among diabetic patients, it has left many individuals unsatisfied with the current rate of commercial artificial pancreas development, stemming the need for further research into novel technologies. Accordingly, the Juvenile Diabetes Research Foundation has marked three generations for the development of an artificial pancreas comprising historical landmarks and future prospects which aim to produce an advanced technological system that attempts to mimic the endogenous pancreas, eliminating the need for user input. This review presents a synopsis of the development and evolution of insulin pumps, starting with the earliest technologies available such as continuous subcutaneous insulin infusion and continuous glucose monitoring as separate components, to currently available integrated advanced closed-loop hybrid systems and possible future technologies. The aim of the review is to provide insight of the advantages and limitations of past and currently available insulin pumps with the hope of driving research into novel technologies that attempt to mimic endogenous pancreatic function as closely as possible.
BACKGROUND:Incorrect or harmful lifestyle during youth may impact negatively gonadal function later in life. To reduce the development of risky behaviors a series of health prevention and intervention campaigns have been conducted in Italy. The present study is part of a Sicily Region (Italy) health surveillance program that was carried out on a sample of late adolescents.METHODS:Between March 2022 to December 2022, we enrolled 718 adolescents (15-26 years old) attending the last two years of high school (278 males and 440 females) in the districts of Syracuse, Ragusa, Catania, and Agrigento (Sicily, Italy). All adolescents were invited to complete a questionnaire that explored their lifestyles and the student's knowledge of sexually transmitted diseases (STDs) and the main andrological diseases.RESULTS:Our analysis revealed that 43% of students smoke cigarettes, with a similar gender distribution; one-third of the students use illicit drugs, with a higher prevalence of males than females. More than two-thirds of youngsters reported drinking alcohol with a statistically significant difference between genders. 68.2% of students do not have sexual difficulties and males have a greater tendency to sexual promiscuity than females and only about half of them use condoms. 92% of students surf the Internet every day; boys tend to visit pornographic sites more often than girls.CONCLUSIONS:This survey revealed statistically significant differences between the two genders in terms of lifestyle and sexual habits. In particular, the survey shows that the prevalence of risky behaviour is still extremely high among late adolescents and young adults and that much still needs to be done in terms of prevention and information. Adequate prevention campaigns, to be proposed in the early years of adolescence, should be initiated in order to provide youngsters with adequate preparation in terms of healthy lifestyle habits.
INTRODUCTION: Nesfatin-1 is a satiety peptide secreted by central, peripheral nervous system and some peripheral tissues. This meta-analysis was conducted to explore the associations with diagnostic accuracy of circulatory nesfatin-1 in polycystic ovary syndrome (PCOS).EVIDENCE ACQUISITION: Relevant studies were retrieved by online database and manual searching. The standardized mean differences (SMDs) with 95% confidence intervals (CIs) were obtained by a random-effects meta-analysis. The subgroup analysis based on the Body Mass Index (BMI), fasting insulin (F-INS), and the homeostasis model assessment-estimated insulin resistance (HOMA-IR) was conducted. Meta-analysis of correlations and meta-regression were performed for the associations of nesfatin-1 with metabolic and hormonal covariates. The diagnostic test accuracy (DTA) meta-analysis was conducted for the utility of nesfatin-1 in PCOS. The publication bias was tested with Egger's and Begg's regression tests.EVIDENCE SYNTHESIS: The combined effect size including a total of 14 studies showed a significantly higher nesfatin-1 level in PCOS as compared to controls (SMD=0.93, Z=2.17, P=0.03). The nesfatin-1 was found to be significantly higher in a subgroup of studies with mean BMI>25 kg/m2 (SMD=1.35, Z=2.06, P=0.04), F-INS <13 mIU/mL (SMD=2.74, Z=3.59, P=0.0003), and HOMA-IR >2.7 (SMD=1.58, Z=2.65, P=0.008). The DTA meta-analysis produced a pooled diagnostic odds ratio of 19.58 and area under curve were of 0.888 for nesfatin-1 in PCOS.CONCLUSIONS: The results indicate a multifactorial involvement such as endocrine and metabolic alterations in the form of BMI, insulin and HOMA-IR status with the higher nesfatin-1 levels in PCOS. The promising results of DTA meta-analysis warrants further research into the clinical and prognostic utility of nesfatin-1 in PCOS.
BACKGROUND:The aim of this study was to analyze the prevalence of primary and secondary hyperparathyroidism in patients with primary aldosteronism (PA), and its implication on cardiovascular and metabolic outcomes.METHODS:A retrospective study of patients with PA (exposed cohort, N.=44) and all hypertensive (EH) patients with adrenal lesions without PA nor other adrenal hypersecretion (non-exposed cohort, N.=41) on follow-up at our center between 2016 and 2020.RESULTS:The mean age of patients with PA and EH was 55.1±14.13 and 66.3±10.93 (P<0.001), and 50% of PA and 39.0% of EH were women (P=0.309). At diagnosis, the prevalence of primary hyperparathyroidism in PA was of 18.2%, and all were normocalcemic hyperparathyroidism cases. Globally, no differences were found in the prevalence of primary hyperparathyroidism compared to EH (18.2% vs. 29.3%, P=0.229), but hypercalcemic primary hyperparathyroidism was significantly more prevalent in EH patients than in PA (22.0% vs. 0%, P=0.001). There were 47.7% (N.=21) cases of secondary hyperparathyroidism in patients with PA (4 due to chronic kidney disease (CKD) and vitamin D deficiency, and 17 due to vitamin D deficiency alone). The cardiometabolic profile of patients with PA and hyperparathyroidism (N.=29) was similar to of those patients without hyperparathyroidism (N.=15) at diagnosis and after a median follow-up of 3.6 years (interquartile range 1.1-5.9).CONCLUSIONS:Although primary and secondary hyperparathyroidism are common in patients with PA, their prevalence was similar than the observed in EH patients. Primary hyperparathyroidism is usually mild in PA, appearing as normocalcemic forms. No negative implications of the hyperparathyroidism in the cardiometabolic profile of PA were observed.
BACKGROUND: The Pituitary Tumors Centers of Excellence (PTCOE) concept was established to provide a multimodal approach with careful management of comorbidities. Acromegaly, one of the main concerns of PTCOE per se, leads to increased mortality rates of which cardiovascular disease is an important cause. Increased skin autofluorescence (SAF) was shown to be associated with carotid intima-media thickness (CIMT), a well-established marker of atherosclerosis, and consequently cardiovascular complications. This study aimed to evaluate SAF and CIMT in association with anthropometric, clinical, and biochemical parameters in acromegaly patients and healthy controls.METHODS: The study group included 138 acromegaly patients and 127 healthy controls from the Department of Endocrinology and Metabolism Disease, Marmara University Medical School. Growth hormone, insulin-like growth factor I, lipids, glucose, insulin levels were assessed. Advanced glycation end products (AGEs) were measured by the auto-fluorescence reader. CIMT was measured from the common carotid artery wall on B-mode ultrasound.RESULTS: CIMT and SAF levels were significantly higher in the acromegaly group than the control group. There was a positive correlation between SAF and CIMT both in the total cohort and acromegaly patients. The presence of acromegaly, age, and SAF were the determining factors of CIMT in the whole study cohort.CONCLUSIONS: Our study is the first to examine the relationship between SAF and CIMT in acromegaly patients. We found higher CIMT and enhanced SAF in the acromegaly group compared to the control group with a significant positive correlation in between. The presence of acromegaly was related to increased SAF levels and CIMT. SAF was associated with CIMT in acromegaly patients. Implementation of CIMT and SAF evaluation in this clinical setting may improve cardiovascular complications, particularly in the PTCOE.
BACKGROUND:Ovarian senescence is associated with increased cardiovascular risk. We aimed to evaluate the association between menopausal symptoms and cardiometabolic risk factors in a cohort of apparently healthy middle-aged women. METHODS:The cohort included 2793 peri- and postmenopausal women not on menopausal hormone therapy. Demographic/anthropometric and biochemical/hormonal data were assessed. The severity of menopausal symptoms was evaluated by the Greene Climacteric Scale (GCS). RESULTS:GCS-Total Score was associated with BMI (b=0.12, 95% CI: 0.04 to 0.20), T2DM (b=2.10, 95% CI: 0.06 to 4.15), and late-postmenopause (b=-1.24, 95% CI: -2.17 to -0.33). GCS-psychological score was associated with BMI (b=0.06, 95% CI: 0.00 to 0.11). GCS-Physical Score was associated with BMI (b=0.06, 95% CI: 0.03 to 0.09), central obesity (b=0.18, 95% CI: 0.02 to 0.34), and postmenopause (early-/late-postmenopause vs. perimenopause, b=-0.36, 95% CI: -0.59 to -0.13 and b=-0.65, 95% CI: -0.97 to -0.34, respectively). All GCS-scores were negatively associated with age. GCS-Sexual Score was associated with early-postmenopause (incidence rate ratio (IRR)=1.53, 95% CI: 1.21 to 1.94), central obesity (IRR=1.18, 95% CI: 1.00 to 1.39), smoking, diastolic blood pressure, age. Cox-regression analysis showed that incident T2DM was positively associated with increasing age, BMI, daily alcohol consumption, moderate-to-severe vasomotor symptoms (VMS, OR=1.045, 95% CI: 1.011 to 1.079), and negatively with moderate-to-strenuous physical activity. These associations persisted in lean but not in obese women. CONCLUSIONS:The severity of menopausal symptoms is associated with T2DM, obesity, and smoking in a cohort of peri-/postmenopausal women. VMS were associated with incident T2DM, especially in lean women. These associations must be considered in implementing primary and secondary prevention strategies.
BACKGROUND The aim of this study is to investigate the use of once-weekly semaglutide in a real population of patients with type 2 diabetes mellitus (T2DM) over 70 years in two Spanish hospitals. METHODS An observational, retrospective, and multicenter clinical study was designed. It included 60 patients with T2DM, with a mean age of 76.5 years, 63.3% women, and a mean of 15.5 years of evolution of T2DM, all managed in the outpatient clinical setting. The primary endpoint was the change in HbA1c from baseline to the end of the study. The secondary endpoints included changes in body weight and the proportion of patients achieving HbA1c <7.0% and body weight loss >5%. RESULTS After 12 months of follow-up, the reductions in HbA1c were -0.61±0.9% (P<0.0001) in the total cohort. Body weight reductions were -8.2±5.3 kg (P<0.0001). Overall, 67% reached the objective of an HbA1c level of <7%, and 73% achieved a weight loss of ≥5%. CONCLUSIONS In routine clinical practice in Spain, the use of semaglutide once a week was associated with statistically significant and clinically relevant improvements in HbA1c and body weight in adults aged over 70 years with T2DM, without notable adverse effects, which supports real-world use.
BACKGROUND:The aim of this retrospective study was the elaboration of a new diagnostic model that integrate cytological reports (2017 Bethesda System for Reporting Thyroid Cytopathology) with ultrasonographic features (based on ACR TI-RADS score) to achieve a more accurate definition of indeterminate thyroid nodule malignancy risk. METHODS:Ninety patients submitted to thyroidectomy were divided in three classes: low malignancy risk (AUS/FLUS with TI-RADS 2/TI-RADS 3 and FN/SFN with TI-RADS 2), intermediate malignancy risk (AUS/FLUS with TI-RADS 4/TI-RADS 5 and FN/SFN with TI-RADS 3/TI-RADS 4), and high malignancy risk (FN/SFN with TI-RADS 5). RESULTS:The surgical approach should be recommended in high-risk patients (81.82% of malignancies), carefully evaluated in intermediate risk (25.42%), whereas a conservative approach can be adopted in low-risk patients (0.00%). CONCLUSIONS:The integration of these two multiparametric systems in a Cyto-US score has proven to be a feasible and reliable aid to achieve a more accurate definition of malignancy risk.
BACKGROUND: The vast majority of erectile dysfunction (ED) treatments are currently symptomatic and do not influence disease progression. Regenerative medicine may potentially reverse or stop the progression of complicated ED by restoring erectile capacity. We aimed to evaluate potential safety and effectiveness and the clinical correlates of platelet function before platelet-rich plasma (PRP) injection in men with vascular ED unresponsive to phosphodiesterase-5 inhibitors (PDE-5is).METHODS: A number of 150 patients with vascular ED were enrolled in an open-label, single arm, multicenter, prospective, interventional, non-randomized study. After 1-month pharmacological washout from PDE-5is, the 5-item International Index of Erectile Function (IIEF-5) questionnaire was administered and dynamic penile duplex ultrasound (d-PDU) was performed. Patients then underwent intracavernous PRP injection. One month after treatment, IIEF-5 and d-PDU were evaluated. Primary aim of the study was to assess efficacy and safety of PRP treatment by evaluating the proportion of patients achieving minimal clinically important differences (MCID) in the IIEF-5 questionnaire. Secondary endpoint was to determine whether MPV could correlate with improvement in d-PDU parameters.RESULTS: Most patients (80%) had a significant improvement in ED symptoms (IIEF-5 Score: 12±2.6 vs. 19±3.0; P<0.0001) and in PSV (32±3.5 cm/s vs. 42±7.6 cm/s; P<0.0001) after d-PDU evaluation. The ROC curve analysis showed a significant accuracy (72.1%, CI: 64.0-80.2, P≤0.0001) for MPV in identifying men clinically responding to PRP with favorable MCID≥5 at 1 month follow-up. The MPV<8.95 fL was identified as the best predictor of success rate with a sensitivity of 90% and a specificity of 54.1%.CONCLUSIONS: This study provides the first evidence that PRP could represent an effective and safe option for patients poorly responding to PDE-5is. MPV higher than 8.95 fL may identify patients with poor response to treatment that might benefit of successive re-challenge with PRP.
BACKGROUND:Given the lack of a previous study assessing understandability and considering there is only one study assessing the readability and quality of online information related to thyroid nodules, we aimed to assess the readability, understandability, and quality of online patient education materials on thyroid nodules. METHODS:Materials were identified through an online search performed by inputting the term "thyroid nodule" into Google. A total of 150 websites were identified, 59 met the inclusion criteria. Websites were classified as academic and hospital (N.=29), physician and clinic (N.=7), organization (N.=12), and health information websites (N.=11). The readability was evaluated using an online system performing a group of validated readability tests. The Patient Education Materials Assessment Tool (PEMAT) was utilized to assess the understandability. The quality was evaluated through the Journal of the American Medical Association (JAMA) benchmark criteria. RESULTS:Among all websites, the mean reading grade level was 11.25±1.88 (range, 8-16), well above the recommended sixth grade reading level (P<0.001). The mean PEMAT Score was 57.4±14.5% (range, 31-88%). For all groups of types of websites, the understandability score was below 70%. There was no statistical difference between the groups for the average reading grade level or the PEMAT score (P=0.379 and P=0.26, respectively). The average JAMA benchmark score was 1.86±1.38 (range 0-4), health information-based websites scored the highest (P=0.007). CONCLUSIONS:Online resources on thyroid nodules are written at grade levels above the recommended reading level. Most resources scored poorly using the PEMAT and varied in quality. Future work should focus on developing understandable, high-quality, and grade-level appropriate materials.
BACKGROUND Acromegaly (ACRO) is a chronic rare disease caused by a pathological increase in growth hormone (GH) secretion. In ACRO an increased prevalence of psychiatric disorders has been demonstrated, in particular depressive disorders, associated to a significant deterioration of the quality of life, independently from disease control. In addition, anger feelings, often detected in subjects affected by chronic disease, have not yet been investigated, in pituitary patients. Aim of the study was to evaluate in ACRO patients with a controlled disease, compared to patients suffering for non-functioning pituitary adenoma (NFPA) 1) prevalence of depressive and anxiety disorders, and 2) expression and control of anger feelings. The second purpose was to evaluate the correlation between psychiatric disorders, anger feelings and the "activity of disease," that is active ACRO that needs medical treatment versus cured ACRO. METHODS This is a cross-sectional, observational study, which included 53 patients enrolled at the Neuroendocrinology Outpatient Clinic of "Città della Salute e della Scienza di Torino". Of the 53 enrolled patients (24 male and 29 female), 34 had ACRO, while 19 had NFPA, as control group. All subjects went through the following self-administered, validated psychological tools: SF-36 (Short-Form 36 Item); STAXI - 2; BDI-II (Beck Depression Inventory -II); STAI (State-Trait Anxiety Inventory). Only in ACRO group, patients completed PASQ (Patient-Assessed Acromegaly Symptom Questionnaire) and ACROQoL (Acromegaly Quality of Life Questionnaire) questionnaires. In addition 45 patients underwent the International Neuropsychiatric Short Interview to assess the presence of a psychiatric disorder. For each patient, anthropometric, clinical and biochemical information was collected. RESULTS A higher frequency of psychiatric anxiety and mood disorders (not reported in the medical history) was observed in patients with controlled ACRO. In the SF-36 questionnaire, a lower score was found in the "emotional well-being" items in ACRO compared to NFPA, particularly in those with cured ACRO. Cured acromegalic patients had a worse score in "emotional well-being," "energy/fatigue" and "general health" items. Finally, subjects in ACRO group obtained a lower score in the ability to control anger and a higher score in the physical expression of it, demonstrating a tendency to more aggressive behaviors. CONCLUSIONS This study showed that psychiatric illness is often hidden in patient suffering from ACRO, despite normal IGF-I levels. Recovery from the disease do not necessarily improve QoL scores, in fact in cured patients the quality of life can be even worse.
BACKGROUND:We aimed to determine the cis-expression Quantitative Trait Loci (cis-eQTL) and trans-eQTL of differentially expressed genes (DEGs) in insulin resistance (IR) related pathways.METHODS:The expression profile data for insulin sensitivity (IS) and IR in the adipose tissue of patients with type 2 diabetes mellitus (T2DM) were acquired from the Gene Expression Omnibus databases. Then, the Gene set enrichment analysis (GSEA) and Gene set variation analysis (GSVA) methods were performed to identify the significant enrichment of potential Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways between IS and IR groups, and the Wilcoxon rank sum test was carried out to identify the DEGs related to KEGG pathways. Finally, the cis-eQTLs and trans-eQTLs that can affect the expression of DEGs were screened from the eQTLGen database.RESULTS:The GSEA and GSVA analysis indicated that the mTOR signaling pathway, insulin signaling pathway and T2DM had a strong correlation with the pathological process of T2DM. Furthermore, six genes (ACACA, GYS2, PCK1, PRKAR1A, SLC2A4, and VEGFA) were found to be significantly differentially expressed in IR-related pathways. Finally, we have identified a total of 1073 cis-eQTLs and 24 trans-eQTLs.CONCLUSIONS:We screened out six genes that were significantly differentially expressed in IR-related pathways, including ACACA, GYS2, PCK1, PRKAR1A, SLC2A4, and VEGFA. Moreover, we discovered that these six genes were affected by 1073 cis-eQTLs and 24 trans-eQTLs.
