Short-term glucose variability as a determinant of the healing rate of diabetic foot ulcer: A retrospective study.

BACKGROUND: The aim of this study was to describe the clinical characteristics of people with diabetic foot ulcer (DFU) according to glucose variability (GV) and to investigate the relationship between GV and DFU outcome in a population with type 2 diabetes (T2D) and DFU. METHODS: This is a retrospective study of 300 individuals aged 64.3 years (181 males) treated for DFU in a tertiary-care center with a regular follow-up for 6 months. Laboratory measurements and clinical assessments were collected at baseline. According to the coefficient of variation (CV) cut-off (≥36%), people were divided into two groups (low and high GV). RESULTS: Compared with low GV group (n = 245), high GV group (n = 55) had significant longer duration of diabetes [low vs high GV, mean ± Standard Deviation (SD), 17.8 ± 11.8 vs 22.4 ± 10.8, P = 0.012], higher levels of glycated haemoglobin [median (IQR), 7.4 (6.6, 8.8) vs 8.2 (7.0, 9.6), P = 0.010] and urinary albumin excretion [25.2 (11.9, 77.0) vs 48.0 (23.2, 106.0), P = 0.031]. Moreover, 10 days self-monitoring of blood glucose-derived glycemic metrics were significantly different between groups. No differences among clinical features were found. The multiple logistic regression analysis identified CV and SD as negative predictors of healing. CONCLUSIONS: In a population of people with T2D and DFU treated in a tertiary-care center, individuals with high GV had a 3-fold higher risk of healing failure, as compared with those with low GV. CV and SD were related to poor healing within 6 months follow-up.

Application and accuracy of the EAPC/IASP diagnostic algorithm for neuropathic cancer pain and quantitative sensory testing profile in patients with pain due to cancer.

Introduction: Better diagnosis and treatment of neuropathic cancer pain (NcP) remains an unmet clinical need. The EAPC/IASP algorithm was specifically designed for NcP diagnosis; yet, to date, there is no information on its application and accuracy. Objectives: Our aim was to determine the accuracy of the EAPC/IASP algorithm compared with the Neuropathic Special Interest Group grading system (gold standard) and to describe patients' sensory profile with quantitative sensory testing (QST). Methods: This is a cross-sectional observational study conducted in a palliative care and pain outpatient clinic. Patients with cancer pain intensity ≥3 (numerical rating scale 0-10) were eligible. The palliative care physician applied the EAPC/IASP algorithm as a grading system to diagnose probable or definite NcP, and an independent investigator applied the gold standard and performed the QST. Sensitivity and specificity of the EAPC/IASP algorithm were measured in comparison with the gold standard results. Kruskal-Wallis and unequal variance independent-samples t tests were used to compare the QST parameters in patients with and without NcP. Results: Ninety-eight patients were enrolled from August 2020 to March 2023. Sensitivity and specificity for the EAPC/IASP algorithm were 85% (95% CI 70.2-94.3) and 98.3% (95% CI 90.8-100), respectively. Patients with NcP in contrast to patients without NcP showed cold hypoesthesia (P = 0.0032), warm hypoesthesia (P = 0.0018), pressure hyperalgesia (P = 0.02), and the presence of allodynia (P = 0.0001). Conclusion: The results indicate a good performance of the EAPC/IASP algorithm in diagnosing NcP and the QST discriminated well between patients with and without NcP.

A real-world study on the prevalence and risk factors of medication related osteonecrosis of the jaw in cancer patients with bone metastases treated with Denosumab.

AIM: Assessing the incidence of Medication Related Osteonecrosis of the Jaw (MRONJ) in cancer patients with bone metastases receiving Denosumab (Dmab) and identifying potential risk factors. METHODS: A retrospective observational study on consecutive cancer patients with bone metastases, who received at least one dose of Dmab and one follow-up visit. MRONJ crude cumulative incidence (CCI) was estimated considering death without MRONJ as competing event. Multiple regression models were used to study the association between MRONJ incidence and potential risk factors: age, cancer diagnosis, previous bisphosphonates, dental treatments before starting Dmab, extraction or other dental treatment during Dmab, chemotherapy, hormone therapy, and antiangiogenic (AA) agents concurrent use. RESULTS: On 780 patients included (median follow-up 17 months), 54% and 18% had, respectively, breast and prostate cancer. The mean number of Dmab administration was 12. Fifty-six patients developed MRONJ with a 24- and a 48-month crude cumulative incidence of 5.7% (95% Cl: 4.2%-7.8%) and 9.8% (95% CI: 7.6%-12.7%), respectively. Higher MRONJ incidence was significantly associated with middle aged group (>56 and ≤73), both at univariate and multivariate analysis (p = 0.029 and 0.0106). Dental treatments (Hazard Ratio [HR] = 3.67; p = 0.0001), dental extractions (HR = 23.40; p < 0.0001), and previous BP administration (HR = 2.62; p = 0.0024) were significantly associated with higher MRONJ incidence at multivariate Cox analysis. Although not statistically significant, MRONJ incidence was lower for patients receiving chemotherapy or hormone therapy and higher for those receiving AAs. CONCLUSIONS: The results confirm a clinically relevant incidence of Dmab-induced MRONJ. Dental treatments, especially extraction, during and before Dmab, constitute a serious risk factor. The role of AA concurrent administration deserves further investigations.

Mediterranean Diet and Thyroid: An Interesting Alliance.

The Mediterranean diet, recognized as being cultural heritage by UNESCO, is mostly plant-based and includes a high consumption of whole-grain, fruit, and vegetables with a moderate consumption of alcohol during meals. Thus, it provides a small amount of saturated fatty acids and a high quantity of antioxidants and fiber. For this reason, it has been considered to have an important role in preventing cardiovascular diseases, chronic kidney diseases, type 2 diabetes mellitus, and cancer, but its relationship with thyroid function and diseases is still under debate. The aim of this review was to search for the possible correlation between the Mediterranean diet and thyroid function, and to critically evaluate the pathophysiological link between selected food intake and thyroid disorders.

Outpatient palliative care referral system (PCRS) for patients with advanced cancer: an impact evaluation protocol.

INTRODUCTION: Early palliative care (PC) in the clinical pathway of advanced cancer patients improves symptom control, quality of life and has a positive impact on overall quality of care. At present, standardised criteria for appropriate referral for early PC in oncology care are lacking. The aim of this project is to develop a set of standardised referral criteria and procedures to implement appropriate early PC for advanced cancer patients (the palliative care referral system, PCRS) and test its impact on user perception of quality of care received, on patient quality of life and on the use of healthcare resources. SETTING: Selected oncology clinics and PC outpatient clinic. METHODS AND ANALYSIS: A scoping literature review and an expert consultation through a nominal group technique will be used to revise existing referral tools and to develop a new one, the PCRS. 25 patients will be enrolled in a pilot study to assess feasibility of the implementation of PCRS; 10 interviews with patients and healthcare professionals will be carried out to evaluate applicability.A pretest-post-test quasiexperimental study involving 150 patients before implementation of the PCRS and 150 patients after implementation will be carried out.Patient satisfaction with care received, quality of life and use of resources, and caregiver satisfaction with care will also be assessed to explore the impact of the intervention. ETHICS AND DISSEMINATION: Ethical approval for the study has been granted by the Institutional Review board of the Fondazione IRCCS Istituto Nazionale Tumori; approval reference INT201/19.Results will be disseminated through open access publications and through scientific communication presented at national and international conferences. TRIAL REGISTRATION NUMBER: NCT04936568.

Cancer pain: Results of a prospective study on prognostic indicators of pain intensity including pain syndromes assessment.

BACKGROUND: Pain is a prevalent symptom in patients with advanced cancer. Recognition of prognostic factors associated with pain intensity, could help provide better assessment, leading to better pain management. AIM: identifying prognostic factors which could guide improvements on cancer pain classification. DESIGN: a prospective observational study on chronic cancer pain, exploring the association between average mean pain intensity during a 28 days study follow-up and patients' clinical and pain-related characteristics, including pain syndromes. To evaluate these associations, a mixed model was built. SETTING/PARTICIPANTS: Patients attending a Palliative Care and Pain Outpatient Clinic from May 2015 to June 2019 were screened. Patients with moderate to severe cancer pain who were already receiving or needed treatment with third step WHO ladder opioids were enrolled in the study. Data from 342 patients with at least one follow-up visit were analyzed. RESULTS: Pain intensity decreased significantly for all patients during time (p < 0.001). Age, sex, emotional distress, pain duration and neuropathic pain presence evaluated by the Douleur Neuropathique 4 Questions (DN4) questionnaire were not significantly associated to pain intensity. Breakthrough/episodic pain was associated with higher pain intensity during follow-up (p < 0.001). The diagnosis of pain syndrome was overall significantly associated with mean pain intensity during follow-up (p = 0.016). Particularly, the concurrent presence of visceral and soft (p = 0.026) or soft and nervous tissue pain (p = 0.043) were significantly related to worse outcome, whereas pain due to only soft tissue damage with better outcome (p = 0.032). CONCLUSIONS: The recognition of specific pain syndromes may help to better classify cancer pain.

Telemedicine for outpatient palliative care during COVID-19 pandemics: a longitudinal study.

OBJECTIVES: During the COVID-19 pandemic, telemedicine (TM) emerged as an important mean to reduce risks of transmission, yet delivering the necessary care to patients. Our aim was to evaluate feasibility, characteristics and satisfaction for a TM service based on phone/video consultations for patients with cancer attending an outpatient palliative care clinic during COVID-19 pandemics. METHODS: A longitudinal observational study was conducted from April to December 2020. Consecutive patients were screened for video consultations feasibility. Either patients or their caregivers received video/phone consultations registering reason and intervention performed. Those contacted at least twice were eligible for experience of care assessment. RESULTS: Video consultations were feasible in 282 of 572 screened patients (49%, 95% CI 45% to 52%); 112 patients among the 572 had at least two phone/video consultations and 12 of them had one or more video consultations. Consultations were carried out with patients (56%), caregivers (30%) or both (14%). 63% of the consultations were requested by the patients/caregivers. Reasons for consultation included uncontrolled (66%) or new symptom onset (20%), therapy clarifications (37%) and updates on diagnostic tests (28%). Most interventions were therapy modifications (70%) and appointments' rescheduling (51%). 49 patients and 19 caregivers were interviewed, reporting good care experience (average of 1-5 satisfaction score of 3.9 and 4.2, respectively). The majority (83% and 84%) declared they would use TM after the pandemics. CONCLUSIONS: Although feasibility is still limited for some patients, TM can be a satisfactory alternative to in-person visits for palliative care patients in need of limiting access to the hospital.

Mediterranean diet in type 2 diabetes: An updated overview of pharmacological activities of cardiometabolic and reproductive outcomes.

Mediterranean diet represents an optimal "way of living" to pursue in order to preserve health and well-being. A large body of evidence indicates that the Mediterranean diet is effective in preventing diabetes and improving both glycemic control and cardiometabolic health in people with type 2 diabetes. Moreover, in the recent years a growing interest risen on the importance of dietary style choice in both male and female sexual and reproductive health. This review aims at providing an updated overview of the latest available evidence on the effects of Mediterranean diet on cardiovascular, metabolic, and reproductive health in the context of type 2 diabetes.

Clinical Predictors for Analgesic Response to Radiotherapy in Patients with Painful Bone Metastases.

BACKGROUND: Radiotherapy (RT) reduces pain in about 60% of patients with painful bone metastases, leaving many patients without clinical benefit. This study assesses predictors for RT effectiveness in patients with painful bone metastases. MATERIALS AND METHODS: We included adult patients receiving RT for painful bone metastases in a multicenter, multinational longitudinal observational study. Pain response within 8 weeks was defined as ≥2-point decrease on a 0-10 pain score scale, without increase in analgesics; or a decrease in analgesics of ≥25% without increase in pain score. Potential predictors were related to patient demographics, RT administration, pain characteristics, tumor characteristics, depression and inflammation (C-reactive protein [CRP]). Multivariate logistic regression analysis with multiple imputation of missing data were applied to identify predictors of RT response. RESULTS: Of 513 eligible patients, 460 patients (90 %) were included in the regression model. 224 patients (44%, 95% confidence interval (CI) 39%-48%) responded to RT. Better Karnofsky performance status (Odds ratio (OR) 1.39, CI 1.15-1.68), breast cancer (OR 2.54, CI 1.12-5.73), prostate cancer (OR 2.83, CI 1.27-6.33) and soft tissue expansion (OR 2.00, CI 1.23-3.25) predicted RT response. Corticosteroids were a negative predictor (OR 0.57, CI 0.37-0.88). Single and multiple fraction RT had similar response. The discriminative ability of the model was moderate; C-statistic 0.69. CONCLUSION: This study supports previous findings that better performance status and type of cancer diagnosis predicts analgesic RT response, and new data showing that soft tissue expansion predicts RT response and that corticosteroids is a negative predictor for RT response in patients with painful bone metastases.

Neuropathic pain: clinical classification and assessment in patients with pain due to cancer.

ABSTRACT: Neuropathic cancer pain (NcP) is associated with worse treatment responses and specific therapy indications, but a standardized clinical diagnosis of NcP is still lacking. This is a prospective observational study on outpatients with cancer, comparing different clinical approaches with NcP evaluation. A three-step assessment of NcP was performed using DN4 (cutoff of 4), palliative care physician Clinical Impression, including etiology and pain syndrome identification, and Retrospective Clinical Classification by a board of specialists with the IASP Neuropathic Pain Special Interest Group criteria. Neuropathic cancer pain classification was specifically referred to pain directly due to cancer. Three hundred fifty patients were assessed, and NcP prevalence was 20% (95% confidence interval [CI] 15.9%-24.6%), 36.9%, (95% CI 31.6%-42.1%), and 28.6% (95% CI 23.8%-33.9%) according to DN4, Clinical Impression, and Retrospective Clinical Classification, respectively. Cohen's kappa concordance coefficient between DN4 and Retrospective Clinical Classification was 0.57 (95% CI 0.47-0.67), indicating moderate concordance. Higher percentages of discordance were found for specific pain syndromes such as pain due to deep soft tissue infiltration and pain associated with tenesmus. Disagreement among clinicians accounted also for different NcP diagnoses and highlighted lack of homogeneous clinical criteria. Rigorous application of etiological and syndrome diagnosis to explain pain cause, associated with standardized diagnostic criteria and assessment of pain characteristics, that is also specific for the cancer pain condition could improve clinical classification of NcP.

Long-term diabetic complications as predictors of foot ulcers healing failure: A retrospective study in a tertiary-care center.

AIM: The aim of this study was to investigate the factors involved in healing failure in a population of patients with diabetic foot ulcers (DFU) after one year of follow-up. METHODS: One hundred and forty-four patients were treated for DFU in a tertiary-care center and had a regular follow-up for one year. Laboratory measurements and clinical assessments, including long-term diabetes complications and risk factors for DFU, were collected at baseline and patients were divided in two groups according to the outcome [Healed group (H, n = 91), and Not Healed group (NH, n = 53)]. RESULTS: Compared with H group, NH group had significant higher levels of urinary albumin excretion [H vs NH, median (IQR), 23.5 (10.1, 41.1) vs 26.4 (20.8, 141.1), P = 0.032] and significantly increased prevalence of diabetic kidney disease (DKD) (22% vs 40%, P = 0.038) and Charcot Arthropathy (3% vs 16%, P = 0.025). No differences among the other long-term complications of diabetes, risk factors for DFU or clinical features were found. The multiple logistic regression analysis identified DKD and Charcot Arthropathy as negative predictors of healing. CONCLUSIONS: In a population of people with type 2 diabetes with DFU treated in a tertiary-care center, DKD and Charcot Arthropathy were related to poor healing within one year-follow-up.

Effects of Mediterranean diet on semen parameters in healthy young adults: a randomized controlled trial.

BACKGROUND: Dietary regimens have so far been studied as possible determinants of semen quality and fertility. The aim of this study was to evaluate the effects of a Mediterranean diet, as compared with a low-fat diet, on seminal parameters of young healthy adults from southern Italy. METHODS: In a randomized controlled trial, 160 young adults aged 18-30 years were assigned to Mediterranean diet (N.=80) or a low-fat diet (N.=80). The primary outcome measures were changes in semen parameters after six months. RESULTS: Mean age of participants in the study was 24.7 years. There was no difference in baseline semen parameters of men randomized to Mediterranean diet or low-fat diet. After the entire follow-up, participants in both groups showed a significant increase in sperm concentration and sperm total count, with significant differences favoring the Mediterranean diet group (sperm concentration, 1.93 M/mL 95% CI [1.22 to 3.64], P=0.027; total sperm count 8.02 M 95% CI [1.51 to 15.45], P=0.035). No differences in other semen parameters were found between groups. CONCLUSIONS: In healthy young adults, the consumption of Mediterranean diet was associated with an improvement of both sperm concentration and total count, as compared with a low-fat diet.

EMPATHY: A New Tool for Identifying the Most Suitable Thyroxine Formulation in Hypothyroid Patients.

Background: Therapy of hypothyroidism is based on the administration of appropriate doses of levothyroxine (LT4). A failure to achieve the thyrotropin (TSH) target may be due to poor compliance with the LT4 therapy in about 60% of cases or to malabsorption in about 40% of cases. No tools are available for detecting malabsorption disorders before the choice of the most appropriate therapy. The aim of this study was to validate the Evaluation of Malabsorption in PATients with HYpothyroidism (EMPATHY) questionnaire and to demonstrate its usefulness in indicating the most appropriate therapy. Methods: EMPATHY consists of seven questions that allow the evaluation of several intolerances and allergies. Three hundred (100 males) newly diagnosed hypothyroid patients were enrolled and randomly assigned to complete an EMPATHY questionnaire (150 patients; group 1) or to a control group (150 patients; group 2). The choice of thyroxine formulation and dose for each group was made on the basis of the questionnaire answers or based on the history. Thyroid hormones and TSH were evaluated at enrollment and then every two months for six months; the number of the dose adjustments in the six months for each patient was recorded. Results: Of the 150 patients in each group, 21 (14%) in group 1 and 42 (28%) in group 2 (p = 0.005) needed more than two dose adjustments within six months. After six months of replacement therapy, six (4%) patients in group 1 and 17 (11%) in group 2 (p = 0.03) did not have appropriately controlled hypothyroidism (TSH ≥2.5 mIU/L). A significantly higher LT4 final dose was found in group 2 (148 ± 33 µg/day) than in group 1 (136 ± 28 µg/day; p = 0.003). Conclusions: Validation of EMPATHY provides endocrinologists with a useful tool in clinical practice, permitting a better personalization of LT4 replacement therapy, a more rapid attainment of the target TSH levels, and a decreased need for dose adjustments after initiating therapy.

Radiotherapy for oligometastatic cancer: a survey among radiation oncologists of Lombardy (AIRO-Lombardy), Italy.

AIMS: To evaluate the use of radiotherapy (RT) for oligometastatic cancer (OMC) among radiation oncologists in Lombardy, Italy. METHODS AND STUDY DESIGN: A survey with 12 items regarding data of 2016 was sent to all 34 Lombardy RT centers. The survey included six general items and six specific items regarding patient/disease/treatment characteristics. RESULTS: Thirteen centers answered the survey (38%). All centers responded to general items and 12 centers submitted patient/disease/treatment data. General items The majority of centers (8/13) consider OMC if metastases number is less than 5. The most commonly prescribed dose/fraction is 5-10 Gy (8/13) using schedules of 3-5 fractions (11/13). Patient data items A total of 15.681 patients were treated in 2016 with external beam RT in 12 responding centers, and 1.087 patients were treated for OMC (7%). Primary tumor included lung, prostate, breast, colorectal and other malignancies in 33%, 21%, 12%, 9% and 25% of all OMC patients, respectively. Brain, lymph node, lung, bone, liver and others were the most common treated sites (24%, 24%, 22%, 17%, 8% and 5%, respectively). One and more than one metastasis were treated in 75 and 25% of patients, respectively. The vast majority of patients (95%) were treated with image-guided intensity-modulated RT or stereotactic RT. CONCLUSIONS: Seven percent of all RT patients in Lombardy are treated for OMC. Extreme hypofractionation and high-precision RT are commonly employed. The initiative of multicenter and multidisciplinary collaboration has been undertaken in order to prepare the platform for prospective and/or observational studies in OMC.

Hypofractionated Whole-Breast Irradiation With or Without Boost in Elderly Patients: Clinical Evaluation of an Italian Experience.

PURPOSE: To examine local control, disease-free survival (DFS), and toxicity in elderly (≥ 65 years) breast cancer patients treated with hypofractionated radiotherapy (hypo-RT) with or without a boost to the tumor bed. PATIENTS AND METHODS: The study was conducted on 752 patients treated from April 2009 to February 2017. Patients received 42.4 Gy in 16 daily fractions (2.65 Gy per fraction). A boost was only administered in cases of grade 3 primary tumor and close or positive margins. Acute and late toxicity was prospectively assessed during and after hypo-RT, based on the Radiation Therapy Oncology Group scale. DFS and local recurrence-free survival were estimated by the Kaplan-Meier method for cumulative probability. Log-rank tests were used to identify differences by subtype. Cox proportional hazard models were used to investigate the impact of various factors on the risk of disease progression. RESULTS: Among the 752 patients treated, 41 (5.5%) experienced disease progression, including 7 (17.1%) exclusively local recurrences; 1 (2.4%) local and nodal recurrence; 1 (2.4%) local and nodal recurrence plus metastasis; 7 (17.1%) nodal recurrences plus metastases; and 25 (61%) exclusively distant metastases. The 5-year DFS, local recurrence-free survival, breast cancer-specific survival, and overall survival rates were 91.8% (95% confidence interval [CI], 88.6-94.2), 98.0% (95% CI, 96.1-99.1), 98.2% (95% CI, 96.5-99.1), and 87.5% (95% CI, 83.8-90.5), respectively. On univariate analysis, the administration of a boost, disease grade (grades 1 and 2 vs. 3), and molecular subtype (triple negative or human epidermal growth factor receptor 2 [HER2] positive, or luminal B vs. luminal A) significantly affected disease progression (P < .01). These findings were confirmed by multivariate analysis. CONCLUSION: Hypo-RT is effective and well tolerated in the elderly population, and the routine use of a boost for patients over 65 years is not justified. Further studies on the boost issue are strongly advocated.

Gender-differences in glycemic control and diabetes related factors in young adults with type 1 diabetes: results from the METRO study.

PURPOSE: To describe gender differences concerning glycemic control, cardiovascular risk factors, diabetic complications, concomitant pathologies, and circulating endothelial progenitor cells (EPCs), in a population of young adults with type 1 diabetes. METHODS: We collected data from 300 consecutively patients (168 males and 132 females), aged 18-30 years, among those admitted at Diabetes Unit of University of Campania "Luigi Vanvitelli" (Naples, Italy) from March 2012 to January 2017. Circulating levels of seven EPCs phenotypes were determined by flow cytometry. RESULTS: As compared to men, women with type 1 diabetes had a significantly higher HbA1c levels (%, 8.4 ± 1.3 vs. 8.1 ± 1.3, P = 0.020), body mass index (Kg/m2, 24.8 ± 4.2 vs. 23.9 ± 3.9, P = 0.034), HDL-cholesterol (mg/dL, 61.7 ± 13.7 vs. 54.7 ± 13.9, P < 0.001), and a lower count of both CD133+KDR+ and CD34+KDR+CD133+ EPCs (P = 0.022, P < 0.001, respectively). A higher proportion of women had overweight/obesity, and thyroiditis; smoking and sexual dysfunctions were more prevalent in men than in women. CONCLUSIONS: Young adults with type 1 diabetes present gender differences with regard to glycemic control, prevalence of some cardiovascular risk factors, sexual dysfunctions and circulating levels of EPCs, most often to the detriment of women.

Comparison of Treatment Outcome Between Invasive Lobular and Ductal Carcinomas in Patients Receiving Partial Breast Irradiation With Intraoperative Electrons.

PURPOSE: To investigate the local outcome of patients after accelerated partial breast irradiation with intraoperative electrons (IORT) for invasive lobular carcinoma (ILC) compared with invasive ductal carcinoma (IDC). METHODS AND MATERIALS: From 1999 to 2007, 2173 patients were treated with breast-conserving surgery and IORT (21 Gy/1 fraction) as the sole local treatment: 252 patients with ILC (11.6%) were compared with 1921 patients with IDC in terms of local control. RESULTS: Compared with the IDC subgroup, patients with ILC had a low-risk profile and were more hormone responsive. The 5- and 10-year in-breast tumor reappearance (IBTR) rates were 5.5% and 14.4%, respectively, for the IDC group and 7.5% and 21.8%, respectively, for the ILC group (log-rank P=.03). The excess risk of IBTR associated with ILC was particularly high for small tumors (≤1 cm: hazard ratio [HR], 2.24; 95% confidence interval [CI], 1.03-4.85), elderly patients (60-69 years: HR, 2.27; 95% CI, 1.11-4.63; ≥70 years: HR, 3.28; 95% CI, 1.08-10.0), low-grade tumors (grade 1: HR, 3.50; 95% CI, 1.05-11.7), and luminal A molecular subtype (HR, 3.18; 95% CI, 1.49-6.77). Among the ILC histologic variants, no difference between classic and nonclassic subgroups was observed, although the signet ring cell and solid variants had the worst local control. CONCLUSIONS: Despite a favorable tumor profile, accelerated partial breast irradiation with IORT led to a higher incidence of IBTRs in patients with ILC compared with those with IDC. Our institutional experience emphasized the importance of the size of the irradiation field, pointing to the use of larger collimators, even when dealing with small tumors, to improve local control.

Effect of a Mediterranean diet on endothelial progenitor cells and carotid intima-media thickness in type 2 diabetes: Follow-up of a randomized trial.

Background We assessed the long-term effects of a Mediterranean diet on circulating levels of endothelial progenitor cells (EPCs) and the carotid intima-media thickness (CIMT) in patients with type 2 diabetes. Design This was a parallel, two-arm, single-centre trial. Methods Two hundred and fifteen men and women with newly diagnosed type 2 diabetes were randomized to a Mediterranean diet ( n = 108) or a low-fat diet ( n = 107). The primary outcome measures were changes in the EPC count and the CIMT of the common carotid artery after the treatment period defined as the end of trial (EOT). Results At the EOT, both the CD34+KDR+ and CD34+KDR+CD133+ counts had increased with the Mediterranean diet compared with the low-fat diet ( p < 0.05 for both). At the EOT evaluation, there was a significant ( p = 0.024) difference of -0.025 mm in the CIMT favouring the Mediterranean diet. Compared with the low-fat diet, the rate of regression in the CIMT was higher in the Mediterranean diet group (51 vs. 26%), whereas the rate of progression was lower (25 vs. 50%) ( p = 0.032 for both). Changes in the CIMT were inversely correlated with the changes in EPC levels (CD34+KDR+, r = -0.24, p = 0.020; CD34+KDR+CD133+, r = -0.28, p = 0.014). At the EOT, changes in levels of HbA1c, HOMA, total cholesterol, high-density lipoprotein cholesterol and systolic blood pressure were significantly greater with the Mediterranean diet than with the low-fat diet. Conclusion Compared with a low-fat diet, a long-term trial with Mediterranean diet was associated with an increase in circulating EPCs levels and prevention of the progression of subclinical atherosclerosis in patients with newly diagnosed type 2 diabetes.

Effects of Mediterranean diet on sexual function in people with newly diagnosed type 2 diabetes: The MÈDITA trial.

AIMS: To assess the long-term effect of Mediterranean diet, as compared with low-fat diet, on sexual function in patients with newly diagnosed type 2 diabetes. METHODS: In a randomized clinical trial, with a total follow-up of 8.1years, 215 men and women with newly diagnosed type 2 diabetes were assigned to Mediterranean diet (n=108) or a low-fat diet (n=107). The primary outcome measures were changes of erectile function (IIEF) in diabetic men and of female sexual function (FSFI) in diabetic women. RESULTS: There was no difference in baseline sexual function in men (n=54 vs 52) or women (n=54 vs 55) randomized to Mediterranean diet or low-fat diet, respectively (P=0.287, P=0.815). Over the entire follow-up, the changes of the primary outcomes were significantly lower in the Mediterranean diet group compared with the low-fat group: IIEF and FSFI showed a significantly lesser decrease (1.22 and 1.18, respectively, P=0.024 and 0.019) with the Mediterranean diet. Baseline C-reactive protein levels predicted erectile dysfunction in men but not female sexual dysfunction in women. CONCLUSIONS: Among persons with newly diagnosed type 2 diabetes, a Mediterranean diet reduced the deterioration of sexual function over time in both sexes.

Contouring of the Pharyngeal Superior Constrictor Muscle (PSCM). A cooperative study of the Italian Association of Radiation Oncology (AIRO) Head and Neck Group.

BACKGROUND AND PURPOSE: Irradiation of the Pharyngeal Superior Constrictor Muscle (PSCM) seems to play a crucial role in radiation-related swallowing dysfunctions. Purpose of our study was to quantify operator-related variability in the contouring of PSCM on Computed Tomography (CT) scans and adherence with contours derived from MR images. MATERIALS AND METHODS: Three sets of treatment planning CT and their corresponding MR images were selected. Contouring of the PSCM was performed using both a literature-based method, derived from literature review, and an optimized method, derived from Magnetic Resonance (MR) images thus obtaining "literature-based" and "optimized" contours. Each operator contoured the PSCM on CT scans according to both methods for three times in three different days. Inter- and intra-operator variability and adherence to a contour obtained from MR images (named "MR-derived" contour) were analyzed. RESULTS: Thirty-four operators participated and 612 contours were obtained. Both intra- and inter-operator variability and adherence to the "MR-derived" contour were significantly different between the two methods (p⩽0.05). The "optimized" method showed a lower intra- and inter-operator variability and a higher adherence to the "MR-derived" contour. CONCLUSIONS: The "optimized" method ameliorates both operator-related variability and adherence with MR images.
