Sindrome della morte improvvisa del lattante (SIDS) in Sicilia: una valutazione dei principali determinanti di accudimento

Aim: to evaluate certain caring behaviors associated with the onset of sudden infant death syndrome (SIDS). Methods: a telephone questionnaire was administered between May and July 2017 to a sample of 1055 Sicilian mothers within 30 days of delivery. A multivariate logistic analysis was conducted considering outcome variables: the sleeping position of the children, exclusive breastfeeding and passive smoking. Results: 62% of the participants place their children in the supine position, 37.9% practice exclusive breastfeeding and 89.0% are not smokers. Being aged < 32 years, having a low level of education and limited economic resources are risk factors for the non-supine positioning of children during sleep. A low level of education, primiparity, non-participation to an antenatal course expose mothers to a greater risk of not practicing exclusive breastfeeding at one month. Postpartum smoking is positively associated with a low level of education. Conclusions: the assessment of the main caring behaviors towards newborns and infants is essential for an effective campaign for reducing the risk of SIDS

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 < .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

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Le sostanze di origine naturale e la loro applicazione nel comparto delle derrate alimentari

Gli insetti dannosi per le derrate conservate sono un problema globale in quanto costituiscono la causa della perdita di enormi quantità di alimenti in tutto il mondo. Infatti, a livello mondiale, circa il 10-30% dei cereali prodotti vengono persi ogni anno a causa dell’attacco degli insetti. Attualmente, il loro controllo si basa principalmente sull’uso di insetticidi di sintesi, che tuttavia risultano dannosi per l’ambiente e per la salute umana da cui l’urgente necessità di tecniche alternative eco-compatibili e sicure. Recentemente, sono stati condotti grandi sforzi da parte della ricerca per identificare e caratterizzare prodotti naturali ad attività insetticida da utilizzare contro le specie di insetti dannosi per le derrate. Questi, detti anche biopesticidi sono un ampio gruppo di prodotti che comprende sostanze vegetali (oli fissi ed essenziali, estratti non volatili e polveri vegetali), polveri inerti, feromoni e composti derivanti da microrganismi (funghi e batteri). In generale, la loro bassa tossicità, l’assenza di residui e la buona efficacia a basse concentrazioni rendono l'uso dei biopesticidi molto promettenti per la difesa delle derrate conservate anche se attualmente il costo relativamente elevato e la variabilità nell'efficacia li rendono un prodotto di nicchia nel mercato degli insetticidi. Infatti, malgrado la loro grande potenzialità e seppure siano state valutate nuove strategie di formulazione è improbabile che a breve i biopesticidi sostituiscano completamente gli agenti chimici nella protezione delle derrate
