Η διερεύνηση και αξιολόγηση των διατροφικών προτύπων αποτελεί πλέον το επίκεντρο της επιδημιολογίας της διατροφής. Τα τελευταία χρόνια, τα διατροφικά πρότυπα έχουν συσχετιστεί με πολλαπλούς δείκτες υγείας και νοσήματα και κυρίως με τα καρδιαγγειακά νοσήματα. Συγκεκριμένα, τα διατροφικά πρότυπα που προκύπτουν από την εκ των υστέρων (a posteriori)μέθοδο έχουν συσχετιστεί τόσο θετικά όσο και αρνητικά με τα καρδιαγγειακά νοσήματα. Η αξιολόγηση της σχέσης των διατροφικών προτύπων με τα καρδιαγγειακά νοσήματα στον ελληνικό πληθυσμό παραμένει ασαφής. Σκοπός: Η διερεύνηση των υποκείμενων διατροφικών προτύπων σε ένα εθνικά αντιπροσωπευτικό δείγμα ενηλίκων στην Ελλάδα και η αξιολόγηση της σχέσης τους με δημογραφικά χαρακτηριστικά, παράγοντες τρόπου ζωής, καρδιαγγειακά νοσήματα και παράγοντες κινδύνου. Μεθοδολογία: Η έρευνα στην οποία βασίστηκε η ανάλυση είναι η Πανελλαδική Μελέτη Διατροφής και Υγείας (ΠΑ.ΜΕ.Δ.Υ.), μία συγχρονική μελέτη με εθνικά αντιπροσωπευτικό δείγμα ανεξαρτήτου φύλου και ηλικιακής ομάδας. Στην ανάλυση συμπεριλήφθησαν μόνο οι ενήλικοι (≥20 ετών) συμμετέχοντες της μελέτης (N=3,552, 41.2% άνδρες; 43.7 ετών, SD: 18.1). Για την ανίχνευση και τον προσδιορισμό των διατροφικών προτύπων εφαρμόστηκε η ανάλυση κυρίων συνιστωσών (Principal Component Analysis, PCA), χρησιμοποιώντας διατροφικά δεδομένα που είχαν συλλεχθεί μέσω 24ώρης ανάκλησης. Ο χαρακτηρισμός των διατροφικών προτύπων βάσει δημογραφικών χαρακτηριστικών και τρόπου ζωής των συμμετεχόντων πραγματοποιήθηκε με ανάλυση διακύμανσης (Analysis of Variance, ANOVA) και τον έλεγχο ανεξαρτησίας χ2. Η παρουσία καρδιαγγειακών νοσημάτων και παραγόντων κινδύνου, όπως η δυσλιπιδαιμία (υψηλά επίπεδα χοληστερόλης ή/και τριγλυκεριδίων) και η υπέρταση, δηλώθηκε από τους ίδιους τους συμμετέχοντες, ενώ η κατηγοριοποίηση έγινε βάσει της Διεθνούς Στατιστικής Ταξινόμησης Νόσων και Συναφών Προβλημάτων Υγείας (Δέκατη Αναθεώρηση) του Παγκόσμιου Οργανισμού Υγείας. Ο λόγος σχετικών πιθανοτήτων (odds ratio) για τα καρδιαγγειακά νοσήματα ανά διατροφικό πρότυπο10 υπολογιστήκε με τη μέθοδο της πολλαπλής λογιστικής παλινδρόμησης (multivariable logistic regression analysis). Αποτελέσματα: Τρία κύρια διατροφικά πρότυπα ανιχνεύθηκαν στον πληθυσμό της μελέτης, τα οποία εξηγούσαν τo 16.5% της διακύμανσης: ένα Παραδοσιακό, ένα Δυτικού τύπου και ένα Συνετό πρότυπο. Το Παραδοσιακό πρότυπο είχε σημαντική θετική συσχέτιση με το ελαιόλαδο, τα μη αμυλούχα λαχανικά και το τυρί. Το Δυτικού τύπου πρότυπο είχε σημαντική θετική συσχέτιση με τα κατεργασμένα δημητριακά, το επεξεργασμένο κρέας και τα ζωικά λίπη. Το Συνετό διατροφικό πρότυπο είχε σημαντική θετική συσχέτιση με τα φρούτα, τα δημητριακά ολικής άλεσης και το γιαούρτι και σημαντική αρνητική συσχέτιση με τρόφιμα τύπου fast-food. Ένα τέταρτο πρότυπο, που ονομάστηκε Βασισμένο σε Σνακ διατροφικό πρότυπο, ανιχνεύθηκε μόνο στις γυναίκες και είχε σημαντική θετική συσχέτιση με τα γλυκά, τα αλμυρά σνακ και τους ξηρούς καρπούς. Τα διατροφικά πρότυπα συσχετίστηκαν με κοινωνικο-οικονομικά χαρακτηριστικά, όπως το επίπεδο εκπαίδευσης, καθώς και με παράγοντες τρόπου ζωής, όπως το κάπνισμα. Η υψηλή προσκόλληση στο Συνετό πρότυπο συσχετίστηκε θετικά με την πρόσληψη πρωτεΐνης και ακόρεστου λίπους και αρνητικά με την πρόσληψη ενέργειας και κορεσμένου λίπους (P≤0.05 για όλα). Αντιθέτως, τα άλλα δύο πρότυπα είχαν θετική συσχέτιση με την πρόσληψη ενέργειας, ολικού και κορεσμένου λίπους. Το Παραδοσιακό πρότυπο συσχετίστηκε επιπλέον με υψηλότερη πρόσληψη μονοακόρεστου λίπους, ενώ το Δυτικού τύπου πρότυπο με υψηλότερη πρόσληψη αλκοόλ (P≤0.001 για όλα). Η προσαρμοσμένη για φύλο και ηλικία λογιστικής παλινδρόμηση, έδειξε αρνητική συσχέτιση μεταξύ του Παραδοσιακού προτύπου και της πιθανότητας παρουσίας καρδιαγγειακών νοσημάτων (OR: 0.53; 95% CI: 0.31-0.92) και θετική συσχέτιση μεταξύ του Δυτικού τύπου προτύπου και της πιθανότητας παρουσίας δυσλιπιδαιμίας (1.49; 1.08-2.05. Το Συνετό πρότυπο διατροφής δεν συσχετίστηκε σημαντικά με την πιθανότητα παρουσίας καμίας από τις υπό μελέτη εκβάσεις.Συμπεράσματα: Δεδομένα από την πρώτη εθνικά αντιπροσωπευτική μελέτη στην Ελλάδα, έδειξαν σημαντικές συσχετίσεις μεταξύ των διατροφικών προτύπων και της παρουσίας καρδιαγγειακών νοσημάτων στον ενήλικο πληθυσμό της χώρας. Τα αποτελέσματα αυτά είναι ιδιαίτερης σημασίας11 για την κατανόηση των διατροφικών συνηθειών στην Ελλάδα και τον σχεδιασμό στοχευμένων πολιτικών δημόσιας υγείας για την προαγωγή της υγιούς διατροφικής συμπεριφοράς.

Background The World Health Organization (WHO) has pointed out that urban taxi drivers and their passengers are at higher risk of transmitting coronavirus disease 19 (COVID-19) due to frequent contact among many people. Facemask wearing is one of the preventive measures recommended to control the transmission of the virus. A lack of evidence of the proportion of facemask wearing among taxi drivers and associated factors in Ethiopia, including Dessie City and Kombolcha Town, hinders the design of targeted interventions to advocate for facemask use. This study was designed to address this gap. Methods A cross-sectional study was conducted among 417 taxi drivers in Dessie City and Kombolcha Town from July to August, 2020. The study participants were selected using a simple random sampling technique after proportionally allocating the sample size from the total number of taxi drivers working in Dessie City and Kombolcha Town. The data were collected by trained data collectors using a structured questionnaire and an on-the-spot observational checklist. The collected data were checked, coded and entered to EpiData version 4.6 and exported to Statistical Package for Social Sciences (SPSS) version 25.0 for data cleaning and analysis. Bivariate (Crude Odds Ratio [COR]) and multivariable (Adjusted Odds Ratio [AOR]) logistic regression analyses were employed using 95% CI (confidence interval). From bivariate logistic regression analysis, variables with p-value < 0.250 were retained into multivariable logistic regression analysis. Then, from the multivariable analysis, variables with p-value < 0.050 were declared as factors significantly associated with facemask wearing among taxi drivers in Dessie City and Kombolcha Town. Main findings The proportion of taxi drivers who wore a facemask was 54.68% [95%CI: 50.10–59.7%]. The majority (58.3%) of drivers were using cloth facemasks, followed by N95 facemasks (24.5%) and surgical facemasks (17.3%). Out of the total 417 taxi drivers, more than two-thirds (69.8%) of them had a good knowledge about COVID-19 and 67.6% of taxi drivers had a positive attitude towards taking precautions against transmission of COVID-19. Three-fourths (74.1%) of the taxi drivers believed that wearing a facemask could prevent COVID-19. More than half (52.5%) felt discomfort when wearing a facemask. Almost three-fourths (72.2%) of taxi drivers felt that the presence of local government pressure helped them to wear a facemask. We found that marital status [AOR = 3.14, 95%CI: 1.97–5.01], fear of the disease [AOR = 2.1, 95%CI: 1.28–3.47], belief in the effectiveness of a facemask [AOR = 5.6, 95%CI: 3.1–10.16] and feeling government pressure [AOR = 3.6, 95%CI: 2.16–6.13] were factors significantly associated with wearing a facemask. Conclusion We found that the proportion of facemask wearers among taxi drivers was relatively low in Dessie City and Kombolcha Town. In order to increase that number, government bodies should work aggressively to encourage more taxi drivers to wear a facemask. We also recommend that government and non-government organizations work very closely together to implement strategies that promote facemask use, including increasing the availability of inexpensive facemasks, and monitoring and controlling facemask use.

Abstract Background Limited data are available on practical predictors of successful de-cannulation among the patients who undergo tracheostomies. We evaluated factors associated with failed de-cannulations to develop a prediction model that could be easily be used at the time of weaning from MV. Methods In a retrospective cohort of 346 tracheostomised patients managed by a standardized de-cannulation program, multivariable logistic regression analysis identified variables that were independently associated with failed de-cannulation. Based on the logistic regression analysis, the new predictive scoring system for successful de-cannulation, referred to as the DECAN score, was developed and then internally validated. Results The model included age > 67 years, body mass index < 22 kg/m2, underlying malignancy, non-respiratory causes of mechanical ventilation (MV), presence of neurologic disease, vasopressor requirement, and presence of post-tracheostomy pneumonia, presence of delirium. The DECAN score was associated with good calibration (goodness-of-fit, 0.6477) and discrimination outcomes (area under the receiver operating characteristic curve 0.890, 95% CI 0.853–0.921). The optimal cut-off point for the DECAN score for the prediction of the successful de-cannulation was ≤ 5 points, and was associated with the specificities of 84.6% (95% CI 77.7–90.0) and sensitivities of 80.2% (95% CI 73.9–85.5). Conclusions The DECAN score for tracheostomised patients who are successfully weaned from prolonged MV can be computed at the time of weaning to assess the probability of de-cannulation based on readily available variables.

Low Renin Hypertension

Abstract Background: Medical treatment with mineralocorticoid receptor antagonists (MRAs) is preferred for patients with primary aldosteronism (PA) who are not surgical candidates. Adequate mineralocorticoid receptor blockade, as suggested by renin elevation above suppression levels, has been associated with lower rates of cardiovascular and renal complications as compared with PA with sustained renin suppression. Objectives: To assess the timeline and rates of achieving target renin levels in patients with PA and low renin hypertension treated with MRAs. Patients and Methods: We conducted a retrospective cohort study of adult patients with hypertension who were treated with MRAs in an academic center between 2003-2019. Of these, we included patients who had suppressed renin at baseline, and repeated renin measurement(s) during MRAs therapy. Renin suppression was defined as plasma renin activity (PRA) 1.0 ng/mL/h or direct renin concentration (DRC) 8.0 pg/mL. We excluded patients with adrenal cancer, end-stage renal disease, exogenous glucocorticoids, and critically ill. Mann-Whitney test, Wilcoxon signed rank test, Chi-Square test and multiple logistic regression analysis were employed, as appropriate. Results: So far, 89 patients (45 men), median age 56 (range, 19-84), have been included. Of these, 46% had confirmed PA; 25% had positive PA screening, but no confirmatory tests; and 29% had other forms of low-renin hypertension. On average, patients were on 2.9 1.6 antihypertensive agents; 62% of patients were prescribed beta blockers, and 38% were on K+ supplements. Overall, renin (PRA in 69 cases, and DRC in 20 cases) increased after MRA treatment (from 0.40 [0.10, 0.60] ng/mL/h to 1.10 [0.60, 2.23] ng/mL/h; and from 2.1 [2.1, 3.7] pg/mL to 5.7 [2.9, 16.7] pg/mL, respectively, p&lt;0.0001 for both). The cumulative proportions of patients in whom renin reached target levels during MRA treatment were: 25% at 2 weeks; 38.9% at 1 month; 34.2% at 3 months; 39.5% at 6 months; and 47.2% at 1 year. Age, sex, race, blood pressure, use of beta blockers, renal function, serum K+ and aldosterone concentrations were similar between patients with target vs. suppressed renin. Multiple logistic regression analysis suggested that after adjusting for age and sex, higher MRA dose and higher BMI were associated with higher likelihood of achieving target renin during MRA therapy (odds ratio (95%CI): 1.021 (1.001-1.041) and 1.097 (1.008-1.193), respectively, p&lt;0.05 for both); conversely, beta blockers use tended to be less often associated with target renin (odds ratio, 0.37 (0.13-1.008), p=0.052). Conclusion: Although raising renin above suppression levels is important for reducing the cardiovascular risk associated with PA, this goal is achieved in less than half of patients, even after one year of treatment with MRAs, in an academic setting. Strategies for optimizing PA treatment are critically needed.

We aimed to evaluate the association between the presence of histologic chorioamnionitis (HC) and development of pulmonary hypertension (PH) during neonatal intensive care unit (NICU) stay. Data of preterm infants born at 32 weeks of gestation or less were reviewed. The development of PH and other respiratory outcomes were compared according to the presence of HC. Potential risk factors associated with the development of PH during NICU stay were used for multivariable logistic regression analysis. A total of 188 infants were enrolled: 72 in the HC group and 116 in the no HC group. The HC group infants were born at a significantly shorter gestational age and lower birthweight, with a greater proportion presenting preterm premature rupture of membrane (pPROM) > 18 h before delivery. More infants in the HC group developed pneumothorax ( P = 0.008), and moderate and severe bronchopulmonary dysplasia (BPD; P = 0.001 and P = 0.006, respectively). PH in the HC group was significantly more frequent compared to the no HC group (25.0% versus 8.6%, P = 0.002). Based on a multivariable logistic regression analysis, birthweight ( P = 0.009, odds ratio [OR] = 0.997, 95% confidence interval [CI] = 0.995–0.999), the presence of HC ( P = 0.047, OR = 2.799, 95% CI = 1.014–7.731), and duration of invasive mechanical ventilation (MV) > 14 days ( P = 0.015, OR = 8.036, 95% CI = 1.051–43.030) were significant factors. The presence of HC and prolonged invasive MV in infants with lower birthweight possibly synergistically act against preterm pulmonary outcomes and leads to the development of PH. Verification of this result and further investigation to establish effective strategies to prevent or ameliorate these adverse outcomes are needed.

Background: We have previously shown that multiple prior percutaneous coronary intervention (PCI) procedures adversely affect outcome after subsequent coronary artery bypass grafting (CABG). We were now interested to investigate this effect on a multicentric basis. Methods: Eight cardiac surgical centers from the German Federal State of North-Rhine-Westphalia provided outcome data of 37140 consecutive patients having undergone isolated first-time CABG between 01/2000 and 12/2005. Twenty-two patient characteristics and outcome variables, which are part of a collection of data claimed by the national medical quality-control commission, were retrieved from the individual databases. Three groups of patients were analyzed for overall in-hospital mortality and major adverse cardiac events (MACE): Patients without a previous PCI procedure, patients with 1 previous PCI procedure and patients with ≥2 previous PCI procedures before surgery. Unadjusted univariable and risk-adjusted multivariable logistic regression analysis were applied. Computed propensity-score matching was performed based on 15 patient major risk factors to correct for and minimize selection bias. Results: A total of 10.3% of patients had 1 previous PCI procedure, and 3.7% of patients had ≥2 previous PCI procedures. Risk-adjusted multivariable logistic regression analysis of ≥2 previous PCI significantly correlated with in-hospital mortality (odds ratio [OR], 2.0; confidence interval [CI], 1.4–3.0; P <0.0005) and MACE (OR, 1.5; CI, 1.2–1.9; P <0.0013). After propensity score matching, conditional logistic regression analysis confirmed the results of adjusted analysis. A history of ≥2 previous PCI procedures was significantly associated with in-hospital mortality (OR, 1.9; CI, 1.3–2.7; P =0.0016) and MACE (OR, 1.5; CI, 1.2–1.9; P =0.0019). Conclusions: This large multicentric trial supports earlier results of our single-center analysis, multiple previous PCI procedures significantly increased the event of in-hospital mortality and MACE after subsequent CABG.

Atherosclerotic Stenosis

Background: In acute ischemic stroke (AIS) patients due to intracranial atherosclerosis-related occlusions (ICAS-O), despite successful reperfusion with mechanical thrombectomy (MT), unexpected early reocclusion sometimes occurs and worsens clinical outcome. We investigated prevalence, outcomes, and predictors of early reocclusion within 48 hours of MT in AIS due to ICAS-O. Methods: In 557 consecutive AIS patients who underwent MT from January, 2016 to March, 2019 in two stroke centers, 71 patients due to ICAS-O were retrospectively evaluated. We divided them into two groups: patients with early reocclusion and those without. Clinical and angiographical findings and outcomes were compared between the 2 groups. Multivariable logistic regression analysis was used to investigate predictors of early reocclusion after MT. Results: Of 71 patients (aged 72 ± 10 years; 23 women; median NIHSS score, 15), early reocclusion was observed in 11 (15%). The first procedure for recanalization was stent retriever in 25 patients (35%), Penumbra system in 25 patients (35%), and balloon angioplasty in 21 patients (30%). Of these, 63 patients (88%) received rescue therapy (balloon angioplasty, 50; intracranial stenting, 13). In the early reocclusion group, more number of intraprocedural reocclusion (median [IQR], 3 [2-3] vs. 1 [0-1], p < 0.001), a higher rate of remaining stenosis on the final angiography (67.6 ± 5.9% vs 57.3 ± 15.9%, p = 0.044), and a higher rate of procedure-related adverse events (27% vs 5%, p = 0.043) were observed compared to the other group. On logistic regression analysis, a total number of intraprocedural reocclusion was independently associated with early reocclusion (odds ratio, 31.4; 95% confidence interval, 2.6-375.2). Early reocclusion was related to a low rate of favorable outcome at 90 days (modified Rankin Scale ≤ 2, 9% vs 54%, p = 0.007). Conclusions: In AIS patients due to ICAS-O, early reocclusion within 48 hours was not rare and associated with unfavorable outcome. Patients with repeated intraprocedural reocclusion are at high risk for early reocclusion; they might need follow-up angiographical assessment and intensive antithrombotic treatment.

Abstract We aimed to assess the role of computerized tomography attenuation values (Hounsfield unit—HU) for differentiating pyonephrosis from hydronephrosis and for predicting postoperative infectious complications in patients with obstructive uropathy. We analysed data from 122 patients who underwent nephrostomy tube or ureteral catheter placement for obstructive uropathy. A radiologist drew the region of interest for quantitative measurement of the HU values in the hydronephrotic region of the affected kidney. Descriptive statistics and logistic regression models tested the predictive value of HU determination in differentiating pyonephrosis from hydronephrosis and in predicting postoperative sepsis. A HU cut-off value of 6.3 could diagnose the presence of pyonephrosis with 71.6% sensitivity and 71.5% specificity (AUC 0.76; 95%CI: 0.66–0.85). At multivariable logistic regression analysis HU ≥ 6.3 (p ≤ 0.001) was independently associated with pyonephrosis. Patients who developed sepsis had higher HU values (p ≤ 0.001) than those without sepsis. A HU cut-off value of 7.3 could diagnose the presence of sepsis with 76.5% sensitivity and 74.3% specificity (AUC 0.79; 95%CI: 0.71–0.90). At multivariable logistic regression analysis, HU ≥ 7.3 (p ≤ 0.001) was independently associated with sepsis, after accounting for clinical and laboratory parameters. Measuring HU values of the fluid of the dilated collecting system may be useful to differentiate pyonephrosis from hydronephrosis and to predict septic complications in patients with obstructive uropathy.

Abstract Background: Perceived discrimination has been linked to psychotic experiences (PEs). However, as yet, information is lacking on the relationship between different forms of discrimination and PEs. This study examined this association in the English general population. Methods: Nationally representative, cross-sectional data were analyzed from 7363 adults aged 16 and above that came from the Adult Psychiatric Morbidity Survey, 2007. Self-reported information was obtained on six forms of discrimination (ethnicity, sex, religious beliefs, age, physical health problems/disability, sexual orientation), while PEs were assessed with the Psychosis Screening Questionnaire (PSQ). Multivariable logistic regression analysis was used to assess associations. Results: In a fully adjusted logistic regression analysis, any discrimination was significantly associated with PEs (odds ratio [OR]: 2.47, 95% confidence interval [CI]: 1.75–3.48). All individual forms of discrimination were significantly associated with PEs except sexual orientation. Multiple forms of discrimination were associated with higher odds for PEs in a monotonic fashion with those experiencing ≥ 3 forms of discrimination having over 5 times higher odds for any PE. In addition, experiencing any discrimination was associated with significantly increased odds for all individual forms of PE with ORs ranging from 2.16 (95%CI: 1.40–3.35) for strange experience to 3.36 (95%CI: 1.47–7.76) for auditory hallucination. Conclusion: Different forms of discrimination are associated with PEs in the general population. As discrimination is common at the societal level, this highlights the importance of public policy and evidence-based interventions to reduce discrimination and improve population mental health.

Background. The maternity continuum of care is the continuity of maternal healthcare services that a woman uses, which includes antenatal care (ANC 4+), skill birth attendant (SBA), and postnatal care (PNC) within 48 hours of delivery. It is one of the essential strategies for reducing maternal and newborn mortality. This study aimed to assess the factors associated with the completion of a continuum of maternal healthcare services among mothers who gave birth in the past five years. Methods. A community-based cross-sectional study was conducted from May 01 to June 29, 2019, among 565 randomly selected mothers who gave birth in five years before the study in primary healthcare project implementation districts of north Gondar zone, Amhara National Regional State, Ethiopia. Bivariable and multivariable logistic regression analysis were computed, and in the multivariable logistic regression analysis, adjusted odds ratio (AOR) with 95% confidence interval (CI) and a p value of less than 0.05 were used to identify the associated factors with completion of the continuum of maternal healthcare services. Results. The study revealed that the overall completion of the continuum of maternal healthcare services was 21.60% (95% CI: 18.20, 24.90). Women who were able to read and write (AOR: 2.70, 95% CI: 1.22, 6.04), using car/motorcycle as a means of transportation to get the health facility (AOR: 5.59, 95% CI: 2.29, 9.50), travel time less than an hour to get the health facility (AOR: 4.98, 95% CI: 2.97, 8.38), being satisfied with the service delivery (AOR: 1.89, 95% CI: 1.15, 3.11), and getting health education on maternal healthcare services in the last 6 months (AOR: 2.77, 95% CI: 1.52, 5.05) were factors associated with the completion of the continuum of maternal healthcare services. Conclusions. The completion of the continuum of maternal healthcare services was relatively low, indicating that women were not getting the likely health benefit from the present health services. Therefore, interventions should focus on increasing women’s awareness, improving the availability of services at nearby health facilities, and improving service delivery by considering women’s preferences and needs to increase their satisfaction are essential to increase the completion of maternal healthcare services.
