Cervical Screening in North Sardinia (Italy): Genotype Distribution and Prevalence of HPV among Women with ASC-US Cytology.

The assessment of human papillomavirus (HPV) genotype dynamics could support the adoption of more tailored preventive actions against cervical cancer. The aim of the study was to describe the prevalence of HPV infection, HPV genotype distribution, and the epidemiological characteristics of women with ASC-US cytology since the introduction of HPV-DNA testing in Sardinia (Italy), (March 2016-December 2020). Specimens were tested by RT-PCR for 14 high-risk HPV genotypes. A total of 1186 patients were enrolled, with a median (IQR) age of 41 (38-48) years. Of these women, 48.1% were positive for at least one HPV genotype; 311 (26.2%) women were vaccinated with a median (IQR) age of 38 (30/47) years. The percentage of prevalence of HPV-16, -31, -66, -56, and -51 was 36.3%, 18.7%, 11.9%, 11.4% and 10.7%, respectively. The highest prevalence of infection was found in women aged <41 years, and single women. Moreover, women aged >41 years (OR: 0.51, 95% CI: 0.31-0.86; p-value: 0.01), having parity (OR: 0.57, 95% CI: 0.34-0.96, p-value: 0.04), and higher educational level (OR: 0.39, 95% CI: 0.18-0.87; p-value: 0.02) were associated with a lower CIN2+ risk. We did not find a significant difference in terms of prevalence of HPV-16 infection between vaccinated and non-vaccinated (18.3% vs. 17.1%; p-value < 0.001). Our results support the adoption of nonavalent HPV-vaccine to prevent the most prevalent infections caused by HPV-16 and -31 genotypes and underscore the need of surveillance to implement tailored vaccination programs and preventive strategies.

SARS-CoV-2 Epidemics in Retirement and Nursing Homes in Italy: A New Preparedness Assessment Model after the First Epidemic Wave.

The aim of the study is to evaluate the preparedness of retirement and nursing homes in the city of Sassari at the end of the first wave of the severe acute respiratory syndrome coronavirus 2 epidemic, first by investigating the risk perception of epidemic outbreaks by the facility managers and subsequently by carrying out a field assessment of these facilities. To perform the field assessment, a checklist developed by the CDC (Infection Prevention and Control Assessment Tool for Nursing Homes Preparing for COVID-19) and adapted to the Italian context was used. Fourteen facilities took part in the survey (87.5%). The application of good practices for each survey area was expressed as a percentage with the following median values: restriction policies (87.5%), staff training (53.8%), resident training (67.6%), availability of personal protective equipment (41.7%), infection control practices (73.5%) and communication (80%). Among the facilities, considerable variability was observed in these evaluation fields: only the restriction policies and communication activities were applied uniformly. A discrepancy was found between perceived risk and real danger in the facilities, requiring targeted communication actions. At present, it is necessary to promote a new approach based on the prediction of critical events, thereby providing the means to effectively address them.

Learning from the past in the COVID-19 era: rediscovery of quarantine, previous pandemics, origin of hospitals and national healthcare systems, and ethics in medicine.

After the dramatic coronavirus outbreak at the end of 2019 in Wuhan, Hubei province, China, on 11 March 2020, a pandemic was declared by the WHO. Most countries worldwide imposed a quarantine or lockdown to their citizens, in an attempt to prevent uncontrolled infection from spreading. Historically, quarantine is the 40-day period of forced isolation to prevent the spread of an infectious disease. In this educational paper, a historical overview from the sacred temples of ancient Greece-the cradle of medicine-to modern hospitals, along with the conceive of healthcare systems, is provided. A few foods for thought as to the conflict between ethics in medicine and shortage of personnel and financial resources in the coronavirus disease 2019 era are offered as well.

Atrial fibrillation in a preterm newborn with structurally normal heart.

Atrial fibrillation (AF) is a really uncommon arrhythmia in newborns. Here, we report the case of a 1-day-old infant who was recovered in Neonatal Intensive Care Unit for a twin-to-twin transfusion. The appearance of an unexpected AF was registered at his continuous electrocardiographic monitoring. Both chest X-ray and echocardiographic examination revealed the anomalous insertion of the tip of a central venous catheter (CVC) into the heart ('umbilical artery → inferior vena cava → right atrium → patent foramen ovale → left atrium'). AF ceased as soon as the CVC was extracted from the heart. The mechanical irritation of both atria caused by the malposition of the CVC might be the underlying mechanism responsible for the triggering of AF in this unique case report.

Metabolomics in necrotizing enterocolitis: the state of the art.

INTRODUCTION: Necrotizing enterocolitis (NEC) is a serious inflammation of the bowel that most often affects premature infants. The exact cause of NEC is still poorly understood but investigators believe that these different factors can play an important role: prematurity and immaturity of the intestine of the preterm newborns, differences in the intestinal bacterial colonization and an abnormal immune response. Since the early symptoms of NEC are often rather non-specific, the diagnosis of NEC can be difficult. Therefore, the search for diagnostic biomarkers for NEC remains warranted. This review focuses on the results of recent metabolomics investigations on NEC, providing important contributions to the understanding of the biochemical process characterizing this disease. Areas covered: Only a few metabolomics applications of NEC are reported in the literature. The metabolic pathway principally altered in NEC patients is suggested to be linked to the carbohydrates metabolism and the role of gluconate as a predictive marker for this pathology is investigated. Expert commentary: Biomarkers are crucial as a confident diagnostic tool to make NEC therapy more efficient. Although only a few metabolomics studies have been performed in NEC research, this technique proved to be helpful to understand the pathophysiological mechanisms of this disease.
