Influenza vaccination coverage among medical residents: An Italian multicenter survey

Although influenza vaccination is recognized to be safe and effective, recent studies have confirmed that immunization coverage among health care workers remain generally low, especially among medical residents (MRs). Aim of the present multicenter study was to investigate attitudes and determinants associated with acceptance of influenza vaccination among Italian MRs. A survey was performed in 2012 on MRs attending post-graduate schools of 18 Italian Universities. Each participant was interviewed via an anonymous, self-administered, web-based questionnaire including questions on attitudes regarding influenza vaccination. A total of 2506 MRs were recruited in the survey and 299 (11.9%) of these stated they had accepted influenza vaccination in 2011-2012 season. Vaccinated MRs were older (P = 0.006), working in clinical settings (P = 0.048), and vaccinated in the 2 previous seasons (P < 0.001 in both seasons). Moreover, MRs who had recommended influenza vaccination to their patients were significantly more compliant with influenza vaccination uptake in 2011-2012 season (P < 0.001). "To avoid spreading influenza among patients" was recognized as the main reason for accepting vaccination by less than 15% of vaccinated MRs. Italian MRs seem to have a very low compliance with influenza vaccination and they seem to accept influenza vaccination as a habit that is unrelated to professional and ethical responsibility. Otherwise, residents who refuse vaccination in the previous seasons usually maintain their behaviors. Promoting correct attitudes and good practice in order to improve the influenza immunization rates of MRs could represent a decisive goal for increasing immunization coverage among health care workers of the future. © 2014 Landes Bioscience

Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy

IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P &lt; .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients

Agreement between anatomical M-mode and tissue Doppler imaging in the assessment of fetal atrioventricular annular plane displacement in uncomplicated pregnancies: A prospective longitudinal study

Aim: To evaluate the level of agreement between M-mode and pulsed-wave tissue Doppler imaging (PW-TDI) techniques in assessing fetal mitral annular plane systolic excursion (MAPSE), tricuspid annular plane systolic excursion (TAPSE) and septal annular plane systolic excursion (SAPSE) in a low-risk population. Methods: This prospective longitudinal study included healthy fetuses assessed from 18 to 40 weeks of gestation. Tricuspid annular plane systolic excursion, MAPSE and SAPSE were measured using anatomical M-mode and PW-TDI. The agreement between the two diagnostic tests was assessed using Bland–Altman analysis. Results: Fifty fetuses were included in the final analysis. Mean values of TASPE were higher than that of MAPSE. There was a progressive increase of TAPSE, MAPSE and SAPSE values with advancing gestation. For each parameter assessed, there was an overall good agreement between the measurements obtained with M-mode and PW-TDI techniques. However, the measurements made with M-mode were slightly higher than those obtained with PW-TDI (mean differences: 0.03, 0.05 and 0.03 cm for TAPSE, MAPSE and SAPSE, respectively). When stratifying the analyses by gestational age, the mean values of TAPSE, MAPSE and SAPSE measured with M-Mode were higher compared to those obtained with PW-TDI, although the mean differences between the two techniques tended to narrow with increasing gestation. Tricuspid annular plane systolic excursion, MAPSE and SAPSE measurements were all significantly, positively associated with gestational age (all P &lt; 0.001). Conclusion: Fetal atrioventricular annular plane displacement can be assessed with M-mode technique, or with PW-TDI as the velocity-time integral of the myocardial systolic waveform. Atrioventricular annular plane displacement values obtained with M-mode technique are slightly higher than those obtained with PW-TDI

Diagnostic accuracy of magnetic resonance imaging in detecting the severity of abnormal invasive placenta: a systematic review and meta-analysis

IntroductionAccurate prenatal diagnosis of abnormally invasive placenta (AIP) is fundamental because it significantly reduces maternal morbidities.Material and methodsMedline, Embase, CINAHL and the Cochrane databases were searched. The primary aim of the present review was to elucidate the diagnostic accuracy of prenatal magnetic resonance imaging (MRI) in recognizing the severity of AIP, defined as the depth and topography of invasion. The secondary aim was to ascertain the strength of association between each MRI sign and the depth of placental invasion and to test their individual predictive accuracy in detecting such invasion. Inclusion criteria were studies on women who had prenatal MRI for ultrasound suspicion or the presence of clinical risk factors for AIP. Estimates of sensitivity, specificity, positive and negative likelihood ratios and diagnostic odds ratio were calculated using the hierarchical summary receiver characteristics curve model, and individual data random-effect logistic regression was used to calculate OR.ResultsTwenty studies (1080 pregnancies undergoing MRI mainly for the ultrasound suspicion of AIP) were included. MRI showed a sensitivity of 94.4% [95% confidence interval (CI) 15.8-99.9], 100% (95% CI 75.3-100) and 86.5% (95% CI 74.2-94.4) for detection of placenta accreta, increta and percreta, respectively; the corresponding values for specificity were 98.8% (95% CI 70.7-100), 97.3% (95% CI 93.3-99.3), 96.8% (95% CI 93.5-98.7). MRI identified 100% of cases with S1 and 100% of those with S2 invasion confirmed at surgery. Among the different MRI signs, intra-placental dark bands showed the best sensitivity for the detection of placenta accreta, increta and percreta; as well as abnormal intra-placental vascularity, uterine bulging was associated with a higher risk of increta and percreta, exophitic mass and bladder tenting with placenta percreta.ConclusionPrenatal MRI has an excellent diagnostic accuracy in identifying the depth and the topography of placental invasion. However, these findings come mainly from studies in which MRI was performed as a secondary imaging tool in women already screened for AIP on ultrasound and might not reflect its actual diagnostic performance in detecting the severity of these disorders

Diagnostic accuracy of ultrasound in detecting the depth of invasion in women at risk of abnormally invasive placenta: A prospective longitudinal study

Introduction: The aim of this study was to assess the diagnostic accuracy of ultrasound in detecting the depth of abnormally invasive placenta in women at risk. Material and methods: Prospective longitudinal study including women with placenta previa and at least one prior cesarean delivery or uterine surgery. Depth of abnormally invasive placenta was defined as the degree of trophoblastic invasion through the myometrium and was assessed with histopathological analysis. The ultrasound signs explored were: loss of clear zone, placental lacunae, bladder wall interruption, uterovesical hypervascularity, and increased vascularity in the parametrial region. Results: In all, 210 women were included in the analysis. When using at least one sign, ultrasound had an overall sensitivity of 100% (95% CI 96.5-100) and overall specificity of 61.9 (95% CI 51.9-71.2) for all types of abnormally invasive placenta. Using two ultrasound signs increased the diagnostic accuracy in terms of specificity (100%, 95% CI 96.5-100) but did not affect sensitivity. When stratifying the analysis according to the depth of placental invasion, using at least one sign had a sensitivity of 100% (95% CI 93.7-100) and 100% (95% CI 92.6-100) for placenta accreta/increta and percreta, respectively. Using three ultrasound signs improved the detection rate for placenta percreta with a sensitivity of 100% (95% CI 92.6-100) and a specificity of 77.2% (95% CI 69.9-83.4). Conclusion: Ultrasound has a high diagnostic accuracy in detecting the depth of placental invasion when applied to a population with specific risk factors for anomalies such as placenta previa and prior cesarean delivery or uterine surgery

Agreement between anatomical M-mode and tissue Doppler imaging in the assessment of fetal atrioventricular annular plane displacement in uncomplicated pregnancies: A prospective longitudinal study

Aim To evaluate the level of agreement between M‐mode and pulsed‐wave tissue Doppler imaging (PW‐TDI) techniques in assessing fetal mitral annular plane systolic excursion (MAPSE), tricuspid annular plane systolic excursion (TAPSE) and septal annular plane systolic excursion (SAPSE) in a low‐risk population. Methods This prospective longitudinal study included healthy fetuses assessed from 18 to 40 weeks of gestation. Tricuspid annular plane systolic excursion, MAPSE and SAPSE were measured using anatomical M‐mode and PW‐TDI. The agreement between the two diagnostic tests was assessed using Bland–Altman analysis. Results Fifty fetuses were included in the final analysis. Mean values of TASPE were higher than that of MAPSE. There was a progressive increase of TAPSE, MAPSE and SAPSE values with advancing gestation. For each parameter assessed, there was an overall good agreement between the measurements obtained with M‐mode and PW‐TDI techniques. However, the measurements made with M‐mode were slightly higher than those obtained with PW‐TDI (mean differences: 0.03, 0.05 and 0.03 cm for TAPSE, MAPSE and SAPSE, respectively). When stratifying the analyses by gestational age, the mean values of TAPSE, MAPSE and SAPSE measured with M‐Mode were higher compared to those obtained with PW‐TDI, although the mean differences between the two techniques tended to narrow with increasing gestation. Tricuspid annular plane systolic excursion, MAPSE and SAPSE measurements were all significantly, positively associated with gestational age (all P < 0.001). Conclusion Fetal atrioventricular annular plane displacement can be assessed with M‐mode technique, or with PW‐TDI as the velocity‐time integral of the myocardial systolic waveform. Atrioventricular annular plane displacement values obtained with M‐mode technique are slightly higher than those obtained with PW‐TDI

Hospital admissions for orthostatic hypotension and syncope in later life : insights from the Malmö Preventive Project

OBJECTIVE(S):: We explored incidence, predictors, and long-term prognosis of hospital admissions attributed to reflex syncope and orthostatic hypotension. METHODS:: We analyzed a cohort of 32?628 individuals (68.2% men; age, 45.6?±?7.4 years) without prevalent cardiovascular disease over a follow-up period of 26.6?±?7.5 years. RESULTS:: One thousand and fourteen persons (3.1%, 1.2 per 1000 person-years) had at least 1 hospitalization for orthostatic hypotension (n?=?462, 1.42%) or syncope (n?=?632, 1.94%). Orthostatic hypotension-related hospitalizations were predicted by age [per 1-year increase, hazard ratio 1.14, 95% confidence interval (CI): 1.12–1.16], smoking (hazard ratio 1.35, 95% CI: 1.12–1.64), diabetes (hazard ratio 1.50, 95% CI: 1.00–2.25), baseline orthostatic hypotension (hazard ratio 1.45, 95% CI: 1.05–1.98), in particular, by SBP fall at least 30?mmHg (hazard ratio 3.93, 95% CI: 2.14–7.23), whereas syncope hospitalizations by age (per 1-year increase, hazard ratio 1.09, 95% CI: 1.07–1.11), smoking (hazard ratio 1.27, 95% CI: 1.08–1.49), and hypertension (hazard ratio 1.42, 95% CI: 1.20–1.69). Both syncope-hospitalized and orthostatic hypotension hospitalized patients had higher burden of hospital admissions for other reasons such as cardiovascular, pulmonary, renal disease, or diabetes. During the follow-up, 10?727 (32.9%) died, with 419 deaths preceded by syncope/orthostatic hypotension hospitalization. After adjustment for traditional risk factors, syncope-hospitalization predicted all-cause mortality (hazard ratio 1.16, 95% CI: 1.02–1.31), whereas orthostatic hypotension hospitalization predicted cardiovascular mortality (hazard ratio 1.13, 95% CI: 1.07–1.19). CONCLUSION:: Hospital admissions due to syncope and orthostatic hypotension occur in ≈3% of older individuals and increase with age and comorbidities. Admissions due to syncope are associated with prevalent hypertension, whereas those due to orthostatic hypotension overlap with diabetes and previously identified orthostatic hypotension. Syncope-related admissions predict higher all-cause mortality, whereas orthostatic hypotension-related admissions herald increased cardiovascular mortality

Hospital admissions for orthostatic hypotension and syncope in middle age: insights from the Malmo Preventive Project

Objective(s): We explored incidence, predictors, and long-term prognosis of hospital admissions attributed to reflex syncope and orthostatic hypotension. Methods: We analyzed a cohort of 32 628 individuals (68.2% men; age, 45.6 +/- 7.4 years) without prevalent cardiovascular disease over a follow-up period of 26.6 +/- 7.5 years. Results: One thousand and fourteen persons (3.1%, 1.2 per 1000 person-years) had at least 1 hospitalization for orthostatic hypotension (n = 462, 1.42%) or syncope (n = 632, 1.94%). Orthostatic hypotension-related hospitalizations were predicted by age [per 1-year increase, hazard ratio 1.14, 95% confidence interval (CI): 1.12-1.16], smoking (hazard ratio 1.35, 95% CI: 1.12-1.64), diabetes (hazard ratio 1.50, 95% CI: 1.00-2.25), baseline orthostatic hypotension (hazard ratio 1.45, 95% CI: 1.05-1.98), in particular, by SBP fall at least 30 mmHg (hazard ratio 3.93, 95% CI: 2.14-7.23), whereas syncope hospitalizations by age (per 1-year increase, hazard ratio 1.09, 95% CI: 1.07-1.11), smoking (hazard ratio 1.27, 95% CI: 1.08-1.49), and hypertension (hazard ratio 1.42, 95% CI: 1.20-1.69). Both syncope-hospitalized and orthostatic hypotension hospitalized patients had higher burden of hospital admissions for other reasons such as cardiovascular, pulmonary, renal disease, or diabetes. During the follow-up, 10 727 (32.9%) died, with 419 deaths preceded by syncope/orthostatic hypotension hospitalization. After adjustment for traditional risk factors, syncope-hospitalization predicted all-cause mortality (hazard ratio 1.16, 95% CI: 1.02-1.31), whereas orthostatic hypotension hospitalization predicted cardiovascular mortality (hazard ratio 1.13, 95% CI: 1.07-1.19). Conclusion: Hospital admissions due to syncope and orthostatic hypotension occur in [almost equal to]3% of older individuals and increase with age and comorbidities. Admissions due to syncope are associated with prevalent hypertension, whereas those due to orthostatic hypotension overlap with diabetes and previously identified orthostatic hypotension. Syncope-related admissions predict higher all-cause mortality, whereas orthostatic hypotension-related admissions herald increased cardiovascular mortality

Birthweight Discordance and Neonatal Morbidity in Twin Pregnancies: A Systematic Review and Meta-analysis

Introduction: The aim of this systematic review was to quantify the association between birthweight discordance and neonatal morbidity in twin pregnancies. Material and Methods: MEDLINE, Embase and Cinahl databases were searched. Studies reporting the occurrence of morbidity in twins affected compared with those not affected by birthweight discordance were included. The primary outcome was composite neonatal morbidity (including neurological, respiratory, infectious morbidities, abnormal acid-base status and necrotizing enterocolitis). The secondary outcomes were the individual morbidities. Sub-group analysis according to chorionicity, gestational age at birth and fetal weight (smaller vs larger twin) was also performed. Random-effect head-to-head meta-analyses were used to analyze the data. Results: Twenty studies (10 851 twin pregnancies) were included. The risk of composite morbidity was significantly higher in the pregnancies with birthweight discordance ≥15% (odds ratio [OR] 1.4, 95% confidence interval [CI] 1.0-1.9), ≥20% (OR 2.2, 95% CI 1.40-3.45), ≥25% (OR 2.5, 95% CI 1.8-3.6), and ≥30% (OR 3.4, 95% CI 2.2-3.2). In dichorionic twins, birthweight discordance ≥15% (OR 2.4, 95% CI 1.65-3.46), ≥20% (OR 2.2, 95% CI 1.3-3.8), ≥25% (OR 2.7, 95% CI 1.4-5.1) and ≥30% (OR 3.6, 95% CI 2.3-5.7) were all significantly associated with composite neonatal morbidity. Analysis of monochorionic twins was hampered by the very small number of included studies, which precluded adequate statistical power. Monochorionic twins with a birthweight discordance ≥20% were at significantly higher risk of composite neonatal morbidity (OR 2.2, 95% CI 1.1-4.9) compared with those presenting with lesser degree of discordance. When stratifying the analysis according to gestational age at birth and fetal size, twins with birthweight discordance ≥15%, 20%, 25% and 30% delivered at ≥34 weeks were at higher risk of neonatal morbidity compared with controls, but there was no difference in the risk of morbidity between the larger and the smaller twin in the discordant pair. Conclusions: Birthweight discordance is associated with neonatal morbidity in twin pregnancies. The strength of this association persists for dichorionic twins. It was not possible to extrapolate robust evidence on monochorionic twins due to the low power of the analysis due to the small number of included studies
